+== How to build IoTivity projects ==
+
+IoTivity includes a series of projects. You can find all these projects here:
+ https://gerrit.iotivity.org/gerrit/#/admin/projects/
+
+You can build IoTivity project on Linux / Windows / MAC OSX for various OS(
+Linux, Tizen, Android, Arduino, Windows, MAC OSX, IOS ...).
+The output of the build is in:
+ <top directory of the project>/out/<target_os>/<target_arch>/<build_type>/
+e.g.
+ oic-resource/out/android/armeabi-v7a/release/.
+
+This document takes 'iotivity' project as example, the way to build other
+projects is almost the same.
+
+=== IoTivity project build tool scons ===
+
+Scons is a cross-platform build tool, its usage is quite similar to GNU make.
+To build a project, you just require to run following command at the directory
+where a SConstruct file exists(SConstruct is the entrance of scons build, it's
+equivalent to Makefile of 'make') :
+ $ scons [options] [target]
+
+In additional, usually the scons build script of a project provides useful help
+information(include build options). To see the help information:
+ $ scons [options] -h
+
+Note: If no value is specified for an option, the default value will be used.
+The change of options value may impact the output.
+
+
+=== Prerequites ===
+
+* 1. Scons
+
+Please refer to the following page to install scons:
+ http://www.scons.org/doc/production/HTML/scons-user.html#chap-build-install
+(Note: on Windows, install Python 2.x before installing scons)
+
+* 2. IDE/SDK Prerequites
+To build for some OS (Android / Arduino / IOS ...), an IDE/SDK may be required,
+please go to the relative page to download and install the required IDE/SDK.
+
+Android:
+To build for Android, Andorid NDK and SDK are required.
+ Android NDK: http://developer.android.com/tools/sdk/ndk/index.html
+ Android SDK: http://developer.android.com/sdk/index.html
+(Note: as in some IoTivity projects, C++11 features are used, recommend Android
+ NDK >= r10, according to our test result r10c is the best one currently)
+
+Arduino:
+To build for Arduino, Arduino IDE is required.
+ Arduino IDE: http://arduino.cc/en/Main/Software
+ (Note: recommend install Arduino IDE >=1.5.7)
+
+Arduino builds are dependent on latest Time library. Download it from here:
+ http://www.pjrc.com/teensy/td_libs_Time.html
+and extract to <arduino_ide_root>/libraries/
+
+(Note: If you are using Arduino IDE 1.5.8 BETA on Windows, it may pop up some
+dll isn't found. please copy relative dll from the IDE directory to
+C:\Windows\SysWOW64. IDE 1.5.7 doesn't have this issue. Other version IDE isn't
+tested.)
+
+Apple:
+To build for Mac OSX or IOS, Xcode is required.
+ Xcode: https://developer.apple.com/xcode/downloads/
+
+Java:
+To build the Java code, JDK is required.
+ JDK: http://www.oracle.com/technetwork/java/javase/downloads/index.html
+(If the project doesn't include Java code or you wouldn't like build the
+Java codes, this isn't required)
+
+(Note: for convenience, suggest add the IDE/SDK path in environment variable,
+so you don't need to add it in command line each time. The build script will
+guide you to do that.)
+
+* 3. External libraries
+For Android and IOS build, most of the external libraries are provided as
+binary in oic-utilities project (https://oic-review.01.org/gerrit/oic-utilities).
+Please download it in the same directory as other IoTivity projects. If it's
+in different directory, an additional option (OIC_UITLS) will be required. The
+build command should be:
+ $ scons OIC_UITLS=<path to oic-utilities> [other options] [target]
+
+(Note: for convenience, you can also add it in environment variable. So you
+don't need to add this option in command line each time.)
+ e.g.:
+ $ export OIC_UITLS=<path to oic-utilities project>
+
+
+=== Build IoTivity project on Linux(Ubuntu) ===
+
+Generally, it's required to specify the target OS and target ARCH, that's to say
+tell Scons which OS and which ARCH you'd like build this project for. By default,
+the target OS and ARCH is the same as the host.
+
+Some more options may be required, please care the 'error' notification when build.
+For help about how to set an option, please run:
+ $ scons TARGET_OS=xxx TARGET_ARCH=yyy [XXX=zzz ...] -h
+
+1. Build IoTivity project for Linux
+ $ cd <top directory of the project>
+ $ sudo apt-get install libboost-dev libboost-program-options-dev libexpat1-dev
+ $ scons
+
+2. Build IoTivity project for Android
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=android TARGET_ARCH=xxx
+(xxx can be x86, armeabi, armeabi-v7a, armeabi-v7a-hard. To see all of its
+allowed value, please execute command 'scons TARGET_OS=android -Q -h')
+
+Note: Currently as x86_64/arm64_v8a external library binaries aren't provided,
+you may meet link problem if build executable binary which depends on external
+library for x86_64/arm64_v8a.
+
+3. Build IoTivity project for Arduino
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=arduino TARGET_ARCH=xxx BOARD=yyy
+(xxx can be avr, arm; yyy is the name of the board, to get its allowed value
+run: scons TARGET_OS=arduino TARGET_ARCH=xxx -h. You may see a option 'CPU' in
+the output of above command line, that's due to some boards have different
+processors, to specify the processor, add 'CPU=zzz' in the command line. If no
+'CPU' option exists, that means the board only support one kind of processor,
+it's unnecessary to specify it)
+
+4. Build Iotivity project for Tizen
+ $ cd <top directory of the project>
+ $ gbs build -A xxx --packaging-dir tools/tizen/
+(xxx can be i586 or armv7l, we provide the spec file required by gbs tool at
+toools/tizen directory. gbs is default build tool for Tizen platfrom, we can
+refer the following wiki to setup Tizen development environment:
+https://source.tizen.org/documentation/developer-guide/getting-started-guide)
+
+=== Build IoTivity project on Windows ===
+
+1. Build IoTivity project for Android(It's the same as on Ubuntu)
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=android TARGET_ARCH=xxx
+(xxx can be x86, armeabi, armeabi-v7a, armeabi-v7a-hard ...)
+
+2. Build IoTivity project for Arduino(It's the same as on Ubuntu)
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=arduino TARGET_ARCH=xxx BOARD=yyy
+(xxx can be avr, arm; yyy is the name of the board, to get its allowed value
+run: scons TARGET_OS=arduino TARGET_ARCH=xxx -h. You may see a option 'CPU' in
+the output of above command line, that's due to some boards have different
+processor, to specify the processor, add 'CPU=zzz' in the command line. If no
+'CPU' option exists, that means the board only support one kind of processor,
+it's unnecessary to specify it)
+
+
+Note: Currently most IoTivity project doesn't support Windows, so you can't set
+TARGET_OS to 'windows' except the project support Windows.
+
+That's to say if the project doesn't support Windows, run:
+ $ scons TARGET_OS=windows ....
+or run on Windows
+ $ scons
+may always fail.
+
+
+=== Build IoTivity project on Mac OSX ===
+
+1. Build IoTivity project for Mac OSX
+ $ cd <top directory of the project>
+ $ scons SYS_VERSION=yyy
+(yyy is the OSX version, e.g. 10.9)
+
+2. Build IoTivity project for Android(It's the same as on Ubuntu)
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=android TARGET_ARCH=xxx
+(xxx can be x86, armeabi, armeabi-v7a, armeabi-v7a-hard)
+
+3. Build IoTivity project for IOS
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=ios TARGET_ARCH=xxx SYS_VERSION=yyy
+(xxx can be i386, x86_64, armv7, armv7s, arm64, yyy is IOS version, e.g. 7.0)
+
+Note:
+1) for convenience, a script (auto_build.sh) is provided to run possible build
+at once. Following is the usage:
+
+To build:
+ $ auto_build.sh <path-to-android-ndk> <path-to-arduino-home>
+To clean:
+ $ auto_build.sh -c
+
+2) For Arduino build, the Time library should >=1.3. The old can only be built
+with Arduino IDE 1.0.x

+OICMiddle was written to
+* be part of a demonstration of OIC Yocto capability,
+* act as an example of resource callbacks using class methods,
+* provide a simple promiscuous resource editor for examining OIC systems, and
+* act as a starting code base for further exploration of OIC capabilities.
+
+As a demonstration, it runs on an Minnowboard running a Yocto-built OS, acting
+as a gateway between an Android device (acting as an OIC client) and an
+Edison board (acting as an OIC server) with sensors and actuators.
+
+As an example of resource callbacks, it shows a method of using class methods
+as callbacks, a critical capability not shown in any of the examples in
+iotivity/resource/examples.
+
+As a promiscuous resource editor, it can find, get, put and observe any
+resource using a simple command-line interface using the system console.
+
+As a code base, the command-line editor can be the basis for adding additional
+editing capabilities, like the additions of various filters.
+
+Running OICMiddle with no arguments on a console shows the various capabilities
+it offers. The most important are:
+ -client. Act as an OIC client.
+ -console. Accept command lines from console input to drive the OIC client.
+ -server. Advertise resources found by the OIC client as OIC resources.
+
+The -server capabilites might be the basis for a gateway.
+
+Typing 'help' (or invalid commands) to the console gives a console usage
+message. The important ones are:
+ find Find all resources. Also performed automatically at startup.
+ show Show the found resources and an assigned index.
+ get Get the value(s) of the resource with the given index.
+ put Put one or more resource values for the given index.

+== NOTICE - Transition to SCONS ==
+===============================================================================
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+===============================================================================
+== Rich Stack & Lite Stack ==
+===============================================================================
+
+The OIC-RESOURCE repository (referred as "<oic-resource>") contains two SDKs
+with underlying code (i.e. "stack"). The two SDKs are referred to as "Rich SDK"
+(or "C++ SDK") and "Lite SDK" (or "C SDK"). The associated stacks are referred
+to as "Rich Stack" (or "C++ Stack") and "Lite Stack" (or "C Stack"),
+respectively. The Rich Stack-SDK pair requires that the Lite Stack-SDK pair is
+built under it.
+
+For a list of artifact locations for all possible build processes in the
+OIC-RESOURCE repository, please refer to:
+<oic-resource>/artifact_output_locations.txt.
+
+===============================================================================
+
+The Rich Stack is intended ONLY for Linux Ubuntu 12.04 operating system.
+To build Rich Stack, please follow these requirements:
+- GCC compiler version is 4.6
+- Pre-install the "gnu-libc" libraries package.
+- You have pre-built the Lite Stack for Linux Ubuntu 12.04.
+- You have installed and pre-built Boost 1.54.
+- To compile Rich Unit Tests, you must have Google Test 1.7.0 and must also
+ create/append "local.properties" file at <oic-resource>/csdk/ with the
+ following specified:
+
+ GTEST_DIR=<gtest-1.7.0>
+
+The Lite Stack is intended ONLY for Linux Ubuntu 12.04, Arduino ATMega 2560 with
+Arduino Framework 1.0.5, and Arduino Due with Arduino Framework 1.5.7.
+Tip: Use Cutecom in Ubuntu 12.04 to view logs from Arduino ATMega 2560 and
+Arduino Due.
+
+To build Lite Stack, please follow these requirements for Linux Ubuntu 12.04:
+- GCC compiler version is 4.6
+- Pre-install the "gnu-libc" libraries package.
+
+To build Lite Stack, please follow these requirements for Arduino ATMega 2560:
+- Arduino Framework 1.0.5 is installed. (Newer versions of the Arduino
+ Framework for Arduino ATMega 2560 have not been tested.)
+- AVR-GCC compiler version is 4.5.3 (Distributed with Arduino 1.0.5, no further
+ action necessary if framework was obtained from
+ http://arduino.cc/en/Main/OldSoftwareReleases. Note: Frameworks obtained from
+ apt-get have had different compiler versions.)
+- Unzip the Time Library from here to your Arduino Directory Structure:
+ http://playground.arduino.cc/code/time
+- Apply patch "arduino-1.0.5_linux.patch" at
+ <oic-resource>/tools/arduino/patches to your Arduino Directory Structure at
+ location <Arduino 1.0.5>.
+- Create/Append "local.properties" file at location
+ <oic-resource>/resource/csdk/ with the following specified:
+
+ ARDUINO_DIR := <arduino-1.0.5>
+ ARDUINO_TOOLS_DIR := $(ARDUINO_DIR)/hardware/tools/avr/bin
+
+To build Lite Stack, please follow these requirements for Arduino Due:
+- Arduino Framework 1.5.7 is installed. (Newer versions of the Arduino
+ Framework for Arduino Due have not been tested.)
+- AVR-GCC compiler version is 4.8.3 (Distributed with Arduino 1.5.7, no further
+ action necessary if framework was obtained from
+ http://arduino.cc/en/Main/OldSoftwareReleases. Note: Frameworks obtained from
+ apt-get have had different compiler versions.)
+- Unzip the Time Library from here to your Arduino Directory Structure:
+ http://www.pjrc.com/teensy/td_libs_Time.html
+- Apply patch "arduino-1.5.7_linux.patch" at
+ <oic-resource>/tools/arduino/patches to your Arduino Directory Structure at
+ location <Arduino 1.5.7>.
+- Create/Append "local.properties" file at location
+ <oic-resource>/resource/csdk/ with the following specified:
+
+ ARDUINO_DIR := <arduino-1.5.7>
+ ARDUINO_TOOLS_DIR := $(ARDUINO_DIR)/hardware/tools/avr/bin
+
+Note: If you are building Unit Tests for Linux, building for Arduino Mega, and
+building for Arduino Due you may find it useful to set the "local.properties"
+file to look like this:
+
+GTEST_DIR=<gtest-1.7.0>
+
+ifeq ($(PLATFORM), arduinomega)
+ #Location of arduino sdk for Arduino Mega
+ ARDUINO_DIR := <arduino-1.0.5>
+ ARDUINO_TOOLS_DIR := $(ARDUINO_DIR)/hardware/tools/avr/bin
+else
+ #Location of arduino sdk for Arduino Due
+ ARDUINO_DIR := <arduino-1.5.7>
+ ARDUINO_TOOLS_DIR := $(ARDUINO_DIR)/hardware/tools/gcc-arm-none-eabi-4.8.3-2014q1/bin

+ NOTICE - Transition to SCONS
+-------------------------------------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+-------------------------------------------------------------------------------
+**Linux**
+-------------------------------------------------------------------------------
+To make octbstack.a in release mode:
+
+ make
+
+To make octbstack.a in debug mode:
+
+ make BUILD=debug
+
+-------------------------------------------------------------------------------
+**Arduino**
+-------------------------------------------------------------------------------
+Touch (i.e. create) file named "local.properties" at this directory level with
+the following definition(s):
+
+ ARDUINO_DIR = <PATH_TO_ARDUINO_INSTALL_DIR>/arduino-1.0.5
+ ARDUINO_TOOLS_DIR = <PATH_TO_ARDUINO_TOOLS> (location of avr-g++ and other avr tools)
+
+To make octbstack.a in release mode:
+ make PLATFORM=arduinomega (For Arduino Due, use <arduinodue>)
+
+To make octbstack.a in debug mode:

+
+Dependencies:
+ 1) Patch the Wiznet Ethernet library with the patch available at :
+ oic-utilities/tb/arduino_linux_ethernet_socket_cpp.patch
+ 2) Arduino builds are dependent on latest Time library. Download it from here:
+ http://www.pjrc.com/teensy/td_libs_Time.html
+ 3) Arduino Due has been tested with Arduino 1.5.7 framework.
+ 4) For Arduino Due, binary tools are located in:
+ /hardware/tools/gcc-arm-none-eabi-4.8.3-2014q1/bin
+ 5) For Arduino WiFi, update the WiFi shield with the firmware patches provided
+ by Intel.
+-------------------------------------------------------------------------------
+**Clean-Up**
+-------------------------------------------------------------------------------
+To clean only stack modules:
+
+ make clean
+
+To clean stack modules and libcoap (i.e. networking) modules & its
+dependencies:

+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

+libcoap: A C implementation of IETF Core Application protocol
+
+Copyright (C) 2010--2013 by Olaf Bergmann <bergmann@tzi.org>
+
+ABOUT LIBCOAP
+
+libcoap is a C implementation of a lightweight application-protocol
+for devices that are constrained their resources such as computing
+power, RF range, memory, bandwith, or network packet sizes. This
+protocol, CoAP, is developed in the IETF working group "Constrained
+RESTful Environments (core)", see <http://6lowapp.net>.
+
+PACKAGE CONTENTS
+
+This directory contains a protocol parser and basic networking
+functions for platform with support for malloc() and BSD-style
+sockets. The examples directory contains a client and a server to
+demonstrate the use of this library.
+
+LICENSE INFORMATION

+\`configure' configures libcoap 4.1.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]

+ * the hash function as it applies to the key domain).
+ *
+ * With the items distributed into more buckets, the chain length
+ * (item count) in each bucket is reduced. Thus by expanding buckets
+ * the hash keeps a bound on the chain length. This bounded chain

+ * The calculation of tbl->ideal_chain_maxlen below deserves some

+ * In fractions this is just n/b (n=number of items,b=new num buckets).
+ * Since the ideal chain length is an integer, we want to calculate

+ * hash, so to calculate ceil(n/b) with integers we could write
+ *
+ * ceil(n/b) = (n/b) + ((n%b)?1:0)
+ *
+ * and in fact a previous version of this hash did just that.
+ * But now we have improved things a bit by recognizing that b is
+ * always a power of two. We keep its base 2 log handy (call it lb),

+// NOTICE - Transition to SCONS
+//----------------------------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+//----------------------------------------------------------------------
+
+#1. build "connectivity" project
+ - execute make command in "connectivity/build/" folder.
+
+#2. build "example" for linux
+ - execute make command in "connectivity/samples/linux/" folder.
+
+#3. execute sample program
+ - you should link the "connectivity_abstraction" library.
+ ex. LD_LIBRARY_PATH=../../../build/out ./sample_main
+
+#4 execute sample.sh in "connectivity/samples/linux/" folder
+ ex. $./sample.sh (This will make a clean build and execute application)

+
+ * resource.c (coap_print_link): This function now takes an offset
+ where printing starts. This is used for generating blocks on the
+ fly.
+
+ * net.c (wellknown_response): Added support for Block2 options
+ when generating a response for .well-known/core.
+
+ * block.h (coap_opt_block_num): Fixed handling of zero-length
+ options. COAP_OPT_BLOCK_LAST now returns NULL when the option
+ value's length is zero.
+
+2014-01-07 Olaf Bergmann <bergmann@tzi.org>
+
+ * resource.c (coap_print_link): Output partial resource
+ descriptions. The function now provides a sliding window over the
+ textual representation of the resource. Output starts at the given
+ offset and ends at the buffer's upper bound. The meaning of the
+ return value has changed to allow distinguishing whether or not
+ the resource description has been truncated at the buffer's upper
+ bound.
+ (print_wellknown): Support for the new coap_print_link(). An
+ additional parameter now is used to provide the offset into the
+ resource description. The meaning of the return value has been
+ adjusted accordingly.

+
+ * configure.in: merged with LWIP port from chrysn
+ <https://git.gitorious.org/coap-lwip/coap-lwip.git>. This
+ introduces new compiler flags WITH_POSIX and WITH_LWIP to
+ distinguish target platforms.

+ directive. #warning is now only used for gcc only (close sf bug #15)
+
+ * net.c (wellknown_response): applied patch from chrysn to
+ fix bug in generation of .well-known/core representation
+
+2013-01-21 Olaf Bergmann <bergmann@tzi.org>
+
+ * option.h: renamed option field in coap_opt_iterator_t to
+ next_option to detect erroneous use in old code
+
+2013-01-18 Olaf Bergmann <bergmann@tzi.org>
+
+ * configure.in: new option --with-tests to enable unit tests
+
+ * tests/testdriver.c: unit tests for parser functions
+
+ * pdu.c (coap_pdu_parse): new PDU parser for Klaus-encoding
+ according to coap-13
+
+ * net.c (coap_read): call coap_pdu_parse() to check PDU integrity
+
+ * option.c: Klaus-encoding for coap-13, including new option
+ iterator interface
+
+2012-11-20 Olaf Bergmann <bergmann@tzi.org>
+
+ * net.c (next_option_safe): made option parsing more robust in
+ presence of option jumps
+
+ * pdu.h: new option codes from draft-ietf-core-coap-12
+
+ * option.c (coap_opt_setlength): new function to set option length
+
+ * uri.c (make_decoded_option): use coap_opt_setlength() instead of
+ obsolete macro COAP_OPT_SETLENGTH.
+
+2012-11-19 Olaf Bergmann <bergmann@tzi.org>
+
+ * uri.c (make_decoded_option): use coap_opt_encode() instead of writing
+
+2012-11-03 Olaf Bergmann <bergmann@tzi.org>
+
+ * net.c (coap_read): read new option encoding
+
+2012-11-01 Olaf Bergmann <bergmann@tzi.org>

+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

+libcoap: A C implementation of IETF Core Application protocol
+
+Copyright (C) 2010--2013 by Olaf Bergmann <bergmann@tzi.org>
+
+ABOUT LIBCOAP
+
+libcoap is a C implementation of a lightweight application-protocol
+for devices that are constrained their resources such as computing
+power, RF range, memory, bandwith, or network packet sizes. This
+protocol, CoAP, is developed in the IETF working group "Constrained
+RESTful Environments (core)", see <http://6lowapp.net>.
+
+PACKAGE CONTENTS
+
+This directory contains a protocol parser and basic networking
+functions for platform with support for malloc() and BSD-style
+sockets. The examples directory contains a client and a server to
+demonstrate the use of this library.
+
+LICENSE INFORMATION
+
+This library is published as open-source software without any warranty
+of any kind. Use is permitted under the terms of the GNU General
+Public License (GPL), Version 2 or higher, OR the revised BSD
+license. Please refer to LICENSE.GPL oder LICENSE.BSD for further
+details.
+
+NOTICE - TRANSITION TO SCONS
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+

+\`configure' configures libcoap 4.1.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ * the hash function as it applies to the key domain).
+ *
+ * With the items distributed into more buckets, the chain length
+ * (item count) in each bucket is reduced. Thus by expanding buckets
+ * the hash keeps a bound on the chain length. This bounded chain
+ * length is the essence of how a hash provides constant time lookup.
+ *
+ * The calculation of tbl->ideal_chain_maxlen below deserves some
+ * explanation. First, keep in mind that we're calculating the ideal
+ * maximum chain length based on the *new* (doubled) bucket count.
+ * In fractions this is just n/b (n=number of items,b=new num buckets).
+ * Since the ideal chain length is an integer, we want to calculate
+ * ceil(n/b). We don't depend on floating point arithmetic in this
+ * hash, so to calculate ceil(n/b) with integers we could write
+ *
+ * ceil(n/b) = (n/b) + ((n%b)?1:0)
+ *
+ * and in fact a previous version of this hash did just that.
+ * But now we have improved things a bit by recognizing that b is
+ * always a power of two. We keep its base 2 log handy (call it lb),
+ * so now we can write this with a bit shift and logical AND:
+ *
+ * ceil(n/b) = (n>>lb) + ( (n & (b-1)) ? 1:0)

+Build notes
+
+//-------------------------------------------------
+// NOTICE - Transition to SCONS
+//-------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+//-------------------------------------------------
+// Linux
+//-------------------------------------------------
+To enable logging, ensure that
+ -D TB_LOG
+is set in the compiler flags
+
+//-------------------------------------------------
+// Android
+//-------------------------------------------------
+To enable logging for Android, TB_LOG should be defined in the ./jni/Android.mk file as
+
+LOCAL_CFLAGS := -DTB_LOG
+
+//-------------------------------------------------
+// Arduino
+//-------------------------------------------------
+To enable the logger for Arduino, TB_LOG should be defined in
+Properties|C/C++ Build|Settings|Tool Settings|AVR Compiler|Symbols
+and
+Properties|C/C++ Build|Settings|Tool Settings|AVR C++ Compiler|Symbols
+
+Note: when building for Arduino, force the compiler to use avr-g++ to build logger.c. Or rename logger.c to logger.cpp.
+
+Note: when building for Arduino, several warnings are generated when trying to place strings in
+PROGMEM
+"warning: only initialized variables can be placed into program memory area"
+This appears to be a known gcc bug - https://gcc.gnu.org/bugzilla/show_bug.cgi?id=34734

+// NOTICE - Transition to SCONS
+//---------------------------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+//---------------------------------------------------------------------
+
+loggertests.cpp contain several logger tests that can be used in an Android JNI app.
+
+androidloggertestoutput.txt is a file capture from running loggertests.cpp in an Android JNI app.
+
+Note: to enable the logger for Android, TB_LOG should be defined in the ./jni/Android.mk file as
+
+LOCAL_CFLAGS := -DTB_LOG

+ArduinoLoggerTest.cpp contains several logger tests and can be used in an
+Arduino sketch.
+
+On Arduino, the logger outputs to the serial port using Serial.print.
+
+Run a serial terminal program such as CuteCom at 115200,8,N,1 to view the
+log outputs.
+
+arduinologgertestoutput.txt contains the output captured after running ArduinoLoggerTest.cpp
+
+Note: to enable the logger for Arduino, TB_LOG should be defined in
+Properties|C/C++ Build|Settings|Tool Settings|AVR Compiler|Symbols
+and
+Properties|C/C++ Build|Settings|Tool Settings|AVR C++ Compiler|Symbols
+
+Note: when building for Arduino, force the compiler to use avr-g++ to build logger.c. Or rename logger.c to logger.cpp.
+
+Note: when building for Arduino, several warnings are generated when trying to place strings in
+PROGMEM
+"warning: only initialized variables can be placed into program memory area"
+This appears to be a known gcc bug - https://gcc.gnu.org/bugzilla/show_bug.cgi?id=34734

+# NOTICE - Transition to SCONS
+#==============================================================================
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+#==============================================================================
+# Build instructions for Linux
+#==============================================================================
+
+In ./occoap directory
+clean ==> make clean
+build ==> make
+
+#==============================================================================
+# Unit test instructions for Linux
+#==============================================================================
+
+After building (make), run
+./occoap/bin/debug/occoaptest

+ NOTICE - Transition to SCONS
+-------------------------------------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+-------------------------------------------------------------------------------
+
+To compile for Linux or Android, include ocsocket.c and ocsocket.h in your project.
+Look at the Makefile in ocsocket/test/linux and ocsocket/test/android for compilation dependencies.
+
+To compile for Arduino, include ocsocket_arduino.cpp and ocsocket.h in your project.
+Look at the Makefile in ocsocket/test/arduino for compilation dependencies.
+Note: Patch your Arduino Ethernet Shield library for arduino/libraries/Ethernet/utility/socket.cpp
+to fix recvfrom issue.
+
+Place appropriate local.properties file under test directory to provide local path for \
+GTEST libraries/header files to compile tests.
+
+#Sample local.properties file
+GTEST_LINUX_DIR = /home/gtest-1.7.0
+GTEST_ANDROID_DIR = /home/gtest-1.7.0_android/gtest-1.7.0
+ARDUINO_DIR = /usr/share/arduino

+//-------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+//-------------------------------------------------
+// Linux
+//-------------------------------------------------
+To build, run
+make
+
+To enable logging, ensure that
+-D TB_LOG
+is set in the compiler flags
+
+//-------------------------------------------------
+// Android
+//-------------------------------------------------
+To enable logging for Android, TB_LOG should be defined in the ./jni/Android.mk file as
+
+LOCAL_CFLAGS := -DTB_LOG
+
+//-------------------------------------------------
+// Arduino
+//-------------------------------------------------
+To enable the logger for Arduino, TB_LOG should be defined in
+Properties|C/C++ Build|Settings|Tool Settings|AVR Compiler|Symbols
+and
+Properties|C/C++ Build|Settings|Tool Settings|AVR C++ Compiler|Symbols
+
+Note: when building for Arduino, force the compiler to use avr-g++ to build logger.c. Or rename logger.c to logger.cpp.
+
+Note: when building for Arduino, several warnings are generated when trying to place strings in
+PROGMEM
+"warning: only initialized variables can be placed into program memory area"
+This appears to be a known gcc bug - https://gcc.gnu.org/bugzilla/show_bug.cgi?id=34734

+// NOTICE - Transition to SCONS
+//---------------------------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+

+
+stacktests.cpp is a unit test of the APIs in ocstack.c.
+It uses Google Test for the unit tests. Note that
+the unit tests are only to test the functionality of
+ocstack.c. It is not a system or end-to-end test.
+
+Unit Test Requirements:
+
+1. Install Google Test on a Linux build machine
+2. Create a file called "local.properties" in the
+ root/csdk/stack/test. local.properties is used
+ by the makefile and specifies the path to the
+ Google Test directory on the build machine.
+ Since local.properties is specific to each build
+ system, do not add local.properties to the code repo.
+
+ local.properties should contain GTEST_DIR.
+ For example:
+
+
+ GTEST_DIR := /home/johndoe/utils/gtest-1.7.0
+
+3. The unit test assumes that the "eth0" interface is
+ available. If not, the unit tests will FAIL.
+4. To run the unit test, first build the C OCStack.
+ At the time of this writing this was done by running
+
+ root/csdk/make deepclean
+ root/csdk/make BUILD=release *default
+ root/csdk/make BUILD=debug
+
+5. Next, build the ocstack
+ root/csdk/stack/test/make clean
+ root/csdk/stack/test/make BUILD=release *default
+ root/csdk/stack/test/make BUILD=debug
+
+6. Run the unit test by
+ root/csdk/stack/test/release/stacktests
+ root/csdk/stack/test/debug/stacktests

+// NOTICE - Transition to SCONS
+//---------------------------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+//---------------------------------------------------------------------
+
+ArduinoStackTest.cpp contains several logger tests and can be used in an
+Arduino sketch.
+
+On Arduino, the logger outputs to the serial port using Serial.print.
+
+Run a serial terminal program such as CuteCom at 115200,8,N,1 to view the
+log outputs.
+
+Note: to enable the logger for Arduino, TB_LOG should be defined in
+Properties|C/C++ Build|Settings|Tool Settings|AVR Compiler|Symbols
+and
+Properties|C/C++ Build|Settings|Tool Settings|AVR C++ Compiler|Symbols
+
+Copy logger.c/h, occoap.c/h, and ocstack.c/h, and ocstackinternal.h to the Arduino project
+Note: when building for Arduino, force the compiler to use avr-g++ to build logger.c, stack.c, and occoap.c
+
+Note: when building for Arduino, several warnings are generated when trying to place strings in
+PROGMEM
+"warning: only initialized variables can be placed into program memory area"
+This appears to be a known gcc bug - https://gcc.gnu.org/bugzilla/show_bug.cgi?id=34734

+@section WhoAreWe Who are we?
+
+\li We want to connect the next 25 billion devices for the Internet of Things.
+
+\li We want to provide secure and reliable device discovery and connectivity across multiple OSs and platforms.
+
+\li There are multiple proposals and forums driving different approaches... but no single solution addresses the majority of key requirements.
+
+\li We need industry consolidation around a common, interoperable approach.
+
+\li We need a broad industry consortium of companies to create a scalable solution.
+
+
+@section WhyAreWeDoingThis Why are we doing this?
+
+\li We are defining the specification, certification & branding to deliver reliable interoperability - a connectivity framework that abstracts complexity
+
+\li This standard will be an open specification that anyone can implement and is easy for developers to use
+
+\li It will include IP protection & branding for certified devices (via compliance testing) and service-level interoperability
+
+\li There will also be an Open Source implementation of the standard
+
+\li This Open Source implementation will be designed to enable application developers and device manufacturers to deliver interoperable products across Android, iOS, Windows, Linux, Tizen, and more.
+
+@section WhoNeedsThis Who needs this?
+
+\li Consumers, Enterprise, Industrial, Automotive, Health, etc. who want smart devices to easily interconnect and communicate with appliances, embedded devices, etc.

+\li Developers of operating systems, platforms, and applications who want their products to interoperate seamlessly across many brands and ecosystems.
+
+\li End users who want consistent levels of security and identity across smart devices down to the smallest connected appliance
+
+@section HowWillWeDeliverIt How will we deliver it?
+
+\li Our goal is to define a comprehensive communications framework to enable emerging applications in all key vertical markets.
+
+\li The framework must enable multiple new modes of communication, such as Peer-to-Peer, Mesh & Bridging, Reporting & Control, etc.
+
+\li The framework should include a consistent implementation of identity, authentication and security across the modes of User ID, Enterprise / Industrial ID & Credentials.
+
+\li It should include a sense of proximity for the Internet of Things and Wearable devices and include support for Onboarding and Provisioning.
+
+\li And the framework must support a "building block" architecture and provide an Open Source implementation

+\li A handler to process requests from the stack, and\r
+\li A URI path to register the resource. \r
+The URI path should be rooted (in other words, start with a slash). The stack will construct the fully qualified URI by adding the URI authority to the provided URI path. For example, given a service running on port 5683 in a device at IP address 192.168.1.1, if the application registers a resource with a URI path "/light/1", the resulting fully qualified URI is "oc://192.168.1.1:5683/light/1", which uniquely identifies the resource's location (IP address port and path).\r
+@note Only one resource can be registered at a given URI.\r
+ \r

+\r
+@section Register_Resource_SD Sequence Diagram\r
+The following call sequence diagram outlines the operations performed in the stack when a resource is registered:\r
+\r
+@image HTML seq_register_resource.png\r
+\r
+<b>Step 1</b>:\r
+Assuming the application has created a valid OCPlatform object, the application registers a new resource with the stack by calling OCPlatform::registerResource(...).\r
+\r
+In this example, the call would take the form:\r
+\r
+ platform.registerResource(&handle, "/light/1", "light", "oc.mi.def", handler, OC_DISCOVERABLE)\r
+\r
+The handle is a reference to the resource that is used on other APIs. The URI path ("/light/1") is where on this server that the resource can be located. The URI path is unique; this call will fail if the application attempts to register another resource using an existing URI. The resource type ("light") and interface ("oc.mi.def") are properties of the resource used in the discovery process. The handler is a function called from the stack to process requests. The flags control how the stack should handle the resource. The OC_DISCOVERABLE flag indicates that the resource should be reported if a client performs a resource discovery on this server.\r
+\r
+<b>Step 2</b>:\r
+\r
+The OCPlatform::registerResource(...) method delegates the call to the appropriate instance of the stack (in-process or out-of-process via IPC).\r
+\r
+<b>Step 3</b>:\r
+The internal registerResource(...) method constructs a C++ entity handler and registers it with the C SDK using OCCreateResource(...).\r
+\r
+In this example, the call would take the form:\r
+\r
+ OCCreateResource(&handle, "light", "oc.mi.def", "/light/1", handler, OC_ DISCOVERABLE)\r
+\r
+Many of these parameters are passed through to the C SDK directly. However, the entity handler is a proxy function for the handler passed from OCPlatform::registerResource(...).\r

+@page Guide_Find_Resource Finding A Resource\r
+\r
+This operation returns all resources of given type on the network service. This operation is sent via multicast to all services. However, the filter limits the responders to just those that support the resource type in the query. Currently only exact matches are supported.\r
+\r
+@image HTML seq_find_resource_2.png\r
+\r
+@section Find_Resource_SD Sequence Diagram\r
+\r
+The following sequence diagram illustrates the resource discovery process over the network when using CoAP. The mechanism is different for Bluetooth, SSDP/HTTP, etc. In the case of CoAP, a 'get' request is sent via multicast to all IoTivity devices. Each device processes the query and responds if the request filter is satisfied. \r
+\r
+In the following example, the client requests all of the light resources with a resource type (rt). Both lights respond to the request, but the fan does not.\r
+\r
+@image HTML seq_find_resource_3.png\r
+\r
+\r
+The following sequence diagram describes the call sequence for discovery from the client side.\r
+@image HTML seq_find_resource.png\r
+\r
+Notes:\r
+\li Assuming that the client has a properly initialized OCPlatform object, a C++ SDK client can discover resources by calling OCPlatform::findResources(...).\r
+\r
+In this example, the call would take the form:\r
+\r
+ platform.findResources("", "/oc/core?rt=alpha.light", findHandler)\r
+\r
+The first parameter is the URI authority (target host), which, when empty, indicates that this is for all nodes. The second parameter ("/oc/core?rt=alpha.light") is the URI path and URI query. The URI path ("/oc/core") indicates the resource and the URI query ("rt=alpha.light") is the filter.\r
+\r
+\li The SDK call findResources(...) internally delegates the call directly to the in-process or to the out-of process stack via IPC based on the stack configuration.\r
+\li Within the stack, findResource(...) calls the C API function OCDoResource(...). In this example, the call is OCDoResource(&handle, OC_REST_GET, "/oc/core?rt=alpha.light", 0, 0, OC_NON_CONFIRMABLE, ...)\r
+\li OCDoResource determines which transport is needed to dispatch the request and delegates the call. In the case of CoAP, the following calls are made:\r
+ - Calls OCDoCoapResource(OC_REST_GET, OC_NON_CONFIRMABLE, token, "/oc/core?rt=alpha.light", 0). The token in this example is a nonce that ties a CoAP response back to the CoAP request. Internally, this method creates the CoAP PDU for dispatching.\r
+ - Calls coap_send(context, host, pdu), which is a wrapper for the implementation below.\r
+ - Calls coap_send_impl(context, host, packet), which dispatches the packet to the socket and does the appropriate CoAP bookkeeping.\r
+ - Calls OCSend(socket, buffer, size...), which is a wrapper for the socket implementation as the functions for dispatching a UDP packet can vary in the embedded systems.\r
+\li Servers that offer the resource on the network will reply to the query. The message pump that is evoked from the OCProcess(...) function in the C SDK receives these response packets and dispatches them to the callback associated with the original request based on the CoAP message ID. These responses will come back at the timing defined by their servers. The client stack has timeouts for these responses that are listed in the appendices.\r
+\li As previously mentioned, the stack matches the response to the original request using the message ID and send the results to the callback associated with the request. At this level, the raw payload is presented in JSON format. It is the responsibility of the callback passed to OCDoResource(...) to parse this result.\r
+\li The C++ SDK provides a callback to OCDoResource(...) that will parse the results, construct collections of OCResource objects from the response, and pass them to a C++ client using the handler passed to the platform.findResource(...) method. The handler will be called once for each resource server that responds to the query.\r
+\r
+Notes:\r
+\li Some of the API call parameters have been omitted for brevity.\r
+\li The findResource() method can be used in the following ways:\r
+ - Find all resources on the network that match the provided criteria\r
+ - Query a specific (single) server for the resources that it provides matching the provided criteria\r
+\li The findResource() method may be used multiple times to find a resource\r
+\li The findResource() callback is called from the message pump thread in multithreaded environments\r
+\li Blocking in the findResource() callback will block other stack processing including servicing the network I/O which can cause delays and missed packets.\r
+\r
+<b>Detailed server call sequence diagram</b>\r
+The following sequence diagram illustrates the call sequence for discovery from the server side. \r
+\r
+@note When the request is sent to all nodes, all nodes will run through this sequence.\r
+\r
+@image HTML seq_find_resource_4.png\r
+\r
+Notes:\r
+\li The discovery request under CoAP is handled like any other resource GET request. The request can be received via unicast or multicast, but the response, if any, is always sent via unicast.\r
+\li The stack dispatches the request to an entity handler that is defined by the stack.\r
+\li The handler for "/oc/core", processes the URI query, if any, and builds a list of resources that match the criteria and returns the result in JSON to the network transport.\r
+\li In the case of CoAP, if the request is made to all nodes (multicast) and the resource list is empty, no response is sent to the clients. If the request is directed (unicast) or the resource list has results, the response is sent unicast back the client.\r

+3. Send PUT request to remote device\r
+4. The OCProcess() service function (server-side message pump) reads the packet from the socket and dispatches the request to the entity handler for the provided URI.\r
+5. The entity handler, which was provided by an upper layer when the resource was registered, parses the representation and in the case of the C++ API passes the results to the upper layer handler. In a C only environment, the results would also be processed in the entity handler.\r
+6. The upper layer entity handler written by the app developer/vendor is invoked, and response is formed accordingly.\r
+7. The upper layer entity handler returns success or failure with a response.\r
+8. Returns success or failure to lower layer for transmission to client.\r
+9. Returns success or failure to lower layer for transmission to client.\r
+10. Returns success or failure to lower layer for transmission to client.\r

+\r
+Steps:\r
+1. The client application calls resource.get(...) to retrieve a representation from the resources.\r
+2. The call is marshalled to the stack which is either running in-process or out-of-process (daemon).\r
+3. The C API is called to dispatch the request. The call may look like the following:\r
+OCDoResource(OC_REST_GET, "//192.168.1.11/light/1, 0, 0, OC_CONFIRMABLE, callback); \r
+4. Where CoAP is used as a transport, the lower stack will send a GET request to the target server.\r
+5. On the server side, the OCProcess() function (message pump) receives and parses the request from the socket, then dispatches it to the correct entity handler based on the URI of the request.\r
+6. Where the C++ API is used, the C++ entity handler parses the payload and marshals it to the client application depending on if the server stack is running in-process or out-of-process (daemon).\r
+7. The C++ SDK passes it up the C++ handler associated with the OCResource.\r
+8. The handler returns the result code and representation to the SDK.\r
+9. The SDK marshals the result code and representation to the C++ entity handler.\r
+10. The entity handler returns the result code and representation to the CoAP protocol.\r
+11. The CoAP protocol transports the results to the client device.\r
+12. The results are returned the OCDoResource callback.\r

+@page Guide_Observe Observing resource state [Observe]\r
+\r
+This operation fetches and registers as an observer for the value of a simple resource. In this example, we fetch the state of the light resource. For more implementation details, see "Observing Resources in CoAP" listed in the referenced documents. (https://datatracker.ietf.org/doc/draft-ietf-core-observe/?include_text=1)\r
+\r
+The handling of observation registration is application specific. It should not be assumed that a resource is observable, or a resource can handle any specific number of observers. If the server responds with a success (2.xx) code, the registration is considered successful.\r
+\r
+Notifications from the server to the client may be confirmable or non-confirmable. If the client returns a RST message, the observation registration should be dropped immediately. If the client fails to acknowledge a number of confirmable requests, the server should assume that the client has abandoned the observation and drop the registration.\r
+\r
+If the observed resource is removed, the server sends a NOTFOUND status to all observers.\r
+\r
+If an observed resource fails to notify a client before the max-age of a resource value update, the client should attempt to re-register the observation.\r
+\r
+\r
+@section Observe_SD Sequence Diagram\r
+@image HTML seq_observe.png\r
+\r
+Steps:\r
+1. The client application calls resource.observe(...) to retrieve a representation from the resources.\r
+2. The call is marshalled to the stack which is either running in-process or out-of-process (daemon).\r
+3. The C API is called to dispatch the request. The call may look like this:\r
+OCDoResource(OC_REST_GET | OC_REST_OBSERVE, "//192.168.1.11/light/1, 0, 0, OC_CONFIRMABLE, callback);\r
+4. Where CoAP is used as a transport, the lower stack will send a GET request to the target server. The primary difference between a GET request and an observe request is that the observe request contains an observe option indicating that, in addition to querying this resource, the client wishes to get notifications if/when the resource state changes.\r
+5. On the server side, the OCProcess() function (message pump) receives and parses the request from the socket, then dispatches it to the correct entity handler based on the URI of the request. The request to the entity handler will indicate that the request is both a query and subscription request. The entity handler MAY take note of this, but it is not responsible to tracking the observers. The stack tracks the observers of record.\r
+6. Where the C++ API is used the C++ entity handler parses the payload and marshals it to the client application depending on if the server stack is running in-process or out-of-process (daemon).\r
+7. The C++ SDK passes it up the C++ handler associated with the OCResource.\r
+8. The handler returns the result code and representation to the SDK.\r
+9. The SDK marshals the result code and representation to the C++ entity handler.\r
+10. The entity handler returns the result code and representation to the CoAP protocol.\r
+11. The CoAP protocol transport the results to the client device.\r
+12. The results are returned to the OCDoResource callback.\r
+13. The results are returned to the C++ client application's asyncResultCallback.\r
+14. If the entity handler has registered observers, it will periodically be called with the observe flag set so that it may sample or poll underlying hardware to determine if the state has changes.\r
+15. When the application has deemed that the resource state has changed either via polling (entity handler observe) or via external signal, the application should call OCNotifyObservers(). This tells the stack the observers need updating.\r
+16. For each observer of a changed resource, the entity handler is called to generate a representation that is transmitted to the observing clients. \r
+17. Where CoAP is used as a transport, a packet with content is sent to the devices that have observing clients. The packets may be confirmable or non-confirmable based on application needs.\r
+18. The client-side OCProcess function (message pump) receives the message and matches it to the original request based on the CoAP token ID and dispatches the appropriate \r
+C API callback.\r
+19. The C API callback passes the final results to the C++ client application's asyncResultCallback.\r
+20. When the C++ client no longer desires to receive notifications from the server, it calls observation cancellation method cancelObserve(). \r
+21. The C++ cancellation method calls the OCCancel() function from the C API.\r
+22. OCCancel() finds the observation that is associated with the operation and sends an observe deregistration request to the server.\r

+\r
+\r
+This document covers the architecture and basic operations of the Iotivity Resource API stack, including sample coverage of protocol, flows, APIs and some use cases. It is intended to provide context for the developers using IoTivity APIs and provide a high level architectural overview.\r
+\r
+@section Stack_Blocks Stack Blocks\r
+\r
+The Resource API stack consists of several thin layers of software. In unconstrained environments such as Android*, iOS*, or Microsoft* Windows*, the stack provides APIs in C and C++ which allow developers to talk to both constrained and unconstrained devices via IP networks, with potential support for additional network protocols and wireless technologies. In the first release, the key technologies for connectivity include UDP/IP and the Constrained Application Protocol (CoAP).
+\r

+\r
+@section Terminology Terminology\r
+\r
+<b>Device</b>\r
+A constrained device that has the Thin Block stack installed which enabled one or more services for other Thin Block or Unified Block devices to consume.\r
+\r
+<b>Resource</b>\r
+A resource is a component in a server that can be viewed and controlled by another Thin Block or Unified Block device. There are different resource types, for example a temperature sensor, a light controller etc.\r
+\r
+Resources can be arranged in a hierarchal manner to form a tree of resources. This generic method of structure enables one to model many different topologies of resources.\r
+\r
+@li Example: A light controller could be a resource.\r
+@li Example: A light array could be a set of resources organized in a flat (non-hierarchical) manner.\r
+@li Example: A garage door opener could be a resource; it could host two resources - light and lock.\r
+\r
+A more detailed description of resources and management of resources along with code snippets is provided later in this document.\r
+\r
+<b>Operations</b>\r
+Operations are actions that a Thin Block or Unified Block can perform on attributes associated with a particular resource. Resource attributes can have different operations on it based on the nature of the resource type. Fundamentally, these are GET and PUT operations. Additionally, attributes can also be declared to be observable to enable remote devices to subscribe to changes.\r
+\r
+@li Example: One of the child resources on the garage door opener is the light control; it has a GET operation that allows a device to get the current light state (on / off).\r
+\r
+@section Functionally Functionally\r
+\r
+The initial release of IoTivity includes functionally for:\r
+ @li @ref Guide_Register_Resource "Resource registration"\r
+ @li @ref Guide_Find_Resource "Resource discovery"\r
+ @li Device discovery with filtering\r
+ @li Property attributes (@ref Guide_GET "get"/ @ref Guide_PUT "set"/ @ref Guide_Observe "observe")\r
+ @li Resource tree (resources having sub-resources)\r
+ @li Presence notification service defined as a virtual resource (not detailed in this document)\r
+\r
+@section External_References External References \r
+\r
+The following references may provide guidance to this document.\r
+ @note In some places, the IoTivity design may differ from the CoRE specifications. In these cases, please consider the CoRE specifications as informative but not definitive on the Iotivity design and architecture.\r

+\r
+@section Protocol Protocol Message Format(s)\r
+\r
+The OIC protocol (abbreviated to OC in code) is a REST-like interface similar to HTTP and CoAP. However, it is a one level up abstraction of the those protocols to allow the addition of additional transports including Bluetooth Classic, Bluetooth Smart (BLE), Zigbee or others in the future. To that end, every attempt has been made to keep CoAP and HTTP specific aspects from being expressed directly in the OIC protocol. The following sections describe how specific transports are used to support the OIC protocol and abstractions.\r
+\r
+@subsection Protocol_CoAP Constrained Application Protocol (CoAP)\r
+\r
+Constrained Application Protocol is one of the IoTivity supported transports. It is designed to be used in very simple devices and is particularly targeted for small, low power devices like sensors, switches, etc. The protocol is modeled after HTTP and provides easy translation between HTTP and CoAP. It is UDP-based (instead of TCP), providing support for multicast.\r
+\r
+CoAP is now a standard (RFC7252) as defined by the Internet Engineering Task Force (IETF) Constrained RESTful environments (CoRE) Working Group. Additional RFCs and drafts cover higher order behaviors.\r
+\r
+<b>Message format</b>\r
+The following table contains a brief overview of the contents of a CoAP packet. Use it as a cheat sheet for the following discussion. For details on the Constrain Resource Protocol, see http://datatracker.ietf.org/doc/rfc7252/?include_text=1.\r

+<b>Short-hand notation</b>\r
+\r
+The following two tables provide examples of request and response packets with explanations on the meaning of the short-hand notation used through the description of the queries and replies.\r
+\r
+@note Acknowledgements can come back separate from content. For the purposes of understanding the semantics of the query and responses, we will assume that all responses come back immediately. In production, requests can be acknowledged and the contents sent back at a later time. In addition, retry logic, de-duplication, congestion control and other features of the CoAP protocol libraries are neglected here.\r
+\r
+<b>Request example</b>\r
+\r
+In this example, the request is to the CoRE "core" resource in the well-known namespace. It provides a simple example of a multicast request to a compound URI with a query section.\r

+
+OCICUC is a light framework for rapidly building OIC test/demo/example applications. It provides pre-built
+entry points and handling for things like command line parameters and modularlizes resources, so that
+adding new features or building a new test application is a lightweight undertaking.
+
+.
+├── client.cpp - a multi-resource client, similar to simpleclient
+├── demo_client.hpp - client code, shared between client and multiprocess programs
+├── driver.cpp - ocicuc base driver program
+├── exec.hpp - header for binding with the driver
+├── light_resource.cpp - example resource
+├── light_resource.hpp - example resource
+├── monoprocess.cpp - client and server in a single process
+├── server.cpp - a multi-resource server, similar to simpleserver
+├── small_example.cpp - a near-minimal example program
+├── utility.cpp - utility functions for the demo programs
+└── utility.hpp - utility functions
+
+You can extend the existing programs to add new resource types, etc.. Refer to the help screen for each program
+for further details. For instance, to start a server with 5 resources and then test it with a separate client,
+you could run:
+
+ ./server --nres=5
+
+...and, in another shell:
+
+ ./client --nres=5
+
+To build a new program that hooks into the ocicuc driver program, you just need to define the functions in "exec.hpp",
+for example:
+
+namespace Intel { namespace OCDemo {
+
+int exec(const boost::program_options::variables_map& vm);
+
+auto make_description()
+ -> boost::program_options::options_description;
+
+}} // namespace Intel::OCDemo
+
+You can see an example of a skeleton program in small_example.cpp.
+
+To run a program with default parameters, use "--", for example:
+
+./monoprocess --
+
+Have fun!

+ //! An output archive designed to save data to JSON
+ /*! This archive uses RapidJSON to build serialie data to JSON.
+
+ JSON archives provides a human readable output but at decreased
+ performance (both in time and space) compared to binary archives.
+
+ JSON benefits greatly from name-value pairs, which if present, will
+ name the nodes in the output. If these are not present, each level
+ of the output will be given an automatically generated delimited name.
+
+ The precision of the output archive controls the number of decimals output
+ for floating point numbers and should be sufficiently large (i.e. at least 20)

+ //! An input archive designed to load data from JSON
+ /*! This archive uses RapidJSON to read in a JSON archive.
+
+ Input JSON should have been produced by the JSONOutputArchive. Data can
+ only be added to dynamically sized containers (marked by JSON arrays) -
+ the input archive will determine their size by looking at the number of child nodes.
+ Only JSON originating from a JSONOutputArchive is officially supported, but data
+ from other sources may work if properly formatted.
+
+ The JSONInputArchive does not require that nodes are loaded in the same
+ order they were saved by JSONOutputArchive. Using name value pairs (NVPs),
+ it is possible to load in an out of order fashion or otherwise skip/select
+ specific nodes to load.
+
+ The default behavior of the input archive is to read sequentially starting
+ with the first node and exploring its children. When a given NVP does
+ not match the read in name for a node, the archive will search for that
+ node at the current level and load it if it exists. After loading an out of
+ order node, the archive will then proceed back to loading sequentially from
+ its new position.
+
+ Consider this simple example where loading of some data is skipped:
+
+ @code{cpp}
+ // imagine the input file has someData(1-9) saved in order at the top level node
+ ar( someData1, someData2, someData3 ); // XML loads in the order it sees in the file
+ ar( cereal::make_nvp( "hello", someData6 ) ); // NVP given does not
+ // match expected NVP name, so we search
+ // for the given NVP and load that value
+ ar( someData7, someData8, someData9 ); // with no NVP given, loading resumes at its
+ // current location, proceeding sequentially

+ NOTICE - Transition to SCONS
+-------------------------------------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+-------------------------------------------------------------------------------
+
+To run the oc_logger C sample app, first build liboctbstack.a
+
+cd <root>/csdk
+
+To enable logging
+make BUILD=debug
+else
+make BUILD=release
+
+Next, build the oc_logger C sample app
+
+cd <root>/oc_logger/samples/linux
+
+To enable logging
+make BUILD=debug
+else
+make BUILD=release
+
+The logger sample has two options, default logging or
+a custom logger that can be supplied by the user application
+
+To run the application with the default logger, run
+
+./debug/test_logging -c 0
+
+To run the application using a built in custom console logger, run
+
+./debug/test_logging -c 1
+

+4. In simpleserver.cpp, inside main, \r
+\r
+PlatformConfig cfg;\r
+cfg.ipAddress = "134.134.161.33";\r
+\r
+Modify the above IP address to the IP address of the machine where this server is running. \r
+\r
+Similarly, in simpleclient.cpp, inside main, modify the IP address to the IP address of the machine where the client is running. \r
+\r
+The server and client can run in same machine or in different machines.\r
+\r
+5. To run simpleServer do \91./simpleServer\92 and to run simpleClient do \91./simpleClient\92.\r

+Release notes
+****************************************************************************
+Release date: Dec 6th, 2014.
+OS: Ubuntu 12.0.4 and above

+NOTE: Boost is not distributed but should be installed in the Ubuntu machine.
+*****************************************************************************
+
+Release commit number: de31af
+
+What is new?
+
+Features:
+---------
+
+Slow Response:
+--------------
+This release includes slow response feature which allows a resource entity handler to provide
+a 'slow response' to a client request. If a request is received but the server cannot response
+immediately (example, response data is not available), then the server can response at a later
+time. The same API is used for both immediate and slow response.
+
+GET/PUT request on the batch interface of a collection resource using the default collection
+entity handler will result in each pointed resource’s entity handler being invoked, after which:
+a) if all pointed resources of the collection are local and not-slow, an aggregated
+response will be sent
+b) if collection includes slow local resource(s), an aggregated response is sent only after
+the slowest resource’s entity handler responds with a payload. If one or more slow resource
+entity handlers do not respond, no response is sent to the request, i.e. there is no timeout
+mechanism in current release
+
+Samples demonstrating slow response:
+simpleserver and simpleclient in C++
+ocserverslow and occlientslow in C
+
+Security:
+----------
+1. OCStack is compiled with security only if a valid libtinydtls.a is available
+under oic-resource/resource/csdk/tinydtls directory.
+2. This release provides an API to set device identity and PSK credentials.
+3. Security is NOT supported for Arduino platform.
+
+JSON serialization using Cereal libray
+--------------------------------------
+This release includes modifications which consists of using
+open source library cereal to perform JSON serialization
+and de-serialization in C++ layer. (NOTE: previously we were
+using boost::property tree for JSON parsing)
+
+NOTE: For a nested (array of array of array..) JSON value, we limit to 3-level deep nesting.
+Refer AttributeValue.h for more details.
+
+------------
+API changes:
+------------
+
+--------------------------------------------
+Class OCPlatform (Header file: OCPlatform.h)
+--------------------------------------------
+
+*****************
+sendResponse API
+*****************
+
+This new API allows the application entity handler to send response to a request.
+This API is used in sending a response immediately (if available) or in cases of
+slow response. Due to this change, signature of application entity handler has
+been modified. This introduces changes in application entity handler code.
+Please see below.
+All C++ samples demonstrate the use of sendResponse API.
+
+--------------------------------------------
+Header file: OCApi.h
+--------------------------------------------
+
+typedef std::function<OCEntityHandlerResult(
+ const std::shared_ptr<OCResourceRequest>)> EntityHandler;
+
+Signature of application entity handler has changed. New signature consists only of
+one parameter which is OCResourceRequest pointer. Response is formed and sent via
+sendResponse API. All C++ samples are updated to showcase this modification.
+
+----------------------------------------------------------
+Class OCResourceRequest (Header file: OCResourceRequest.h)
+----------------------------------------------------------
+
+********************

+********************
+
+This new API allows the application entity handler to retrieve request handle
+from the incoming request.
+All C++ samples demonstrate the use of getRequestHandle API.
+
+*********************

+*********************
+
+This new API allows the application entity handler to retrieve resource handle

+
+-------------------------------------------------------------
+Class OCResourceResponse (Header file: OCResourceResponse.h)
+-------------------------------------------------------------
+
+********************

+********************
+
+This new API allows the application entity handler to set request handle in
+the response.
+All C++ samples demonstrate the use of setRequestHandle API.
+
+*********************
+setResourceHandle API
+*********************
+
+This new API allows the application entity handler to set resource handle in

+the response.
+All C++ samples demonstrate the use of setResponseResult API.
+
+-------------------------------------------------------------
+Header file: OCStack.h
+-------------------------------------------------------------
+
+***************************
+OCDoResponse API
+***************************
+
+This new C API allows the application entity handler to send response to a request.
+This API is used in sending a response immediately (if available) or in cases of
+slow response.
+
+-------------------------------------------------------------
+Header file: OCSecurity.h
+-------------------------------------------------------------
+
+***************************
+OCSetDtlsPskCredentials API
+***************************
+
+This new API allows to set DTLS PSK credentials.
+
+------------
+Notes:
+------------
+
+Known issues:
+-------------
+1. When observation is used, server shutdown causes an error (segmentation fault).
+
+Active discovery-
+1. In case of unicast presence with rt, only one rt is permitted per IP address for
+subscribePresence. If multiple subscriptions are done, only first subscribePresence’s rt is used.
+2. For multicast presence, server shutdown (ungraceful) scenario is not notified to the client,
+but graceful shutdowns are notified.
+3. IOT 85
+
+Issues Fixed:
+-------------
+1. IOT 65 (Stopping presence subscription gets infinite callback to handlePresence)
+2. IOT 79 (3 Presence Notifications when a resource is created on the server)
+
+General notes:
+--------------
+Maximum length of URI supported is 64 bytes (sent from the client)
+Maximum length of query supported is 64 bytes (sent from the client)
+Maximum length of request from client and response from server for Arduino is is 256 bytes
+Maximum length of request from client and response from server for non-Ardunio is is 1024 bytes
+
+OIC base supports Arduino WiFi shield.
+This support has been tested with Arduino Mega 2560 and with Arduino 1.0.5 WiFi library.
+Please refer to oic-resource/csdk/README file for building OIC base with WiFi support.
+
+-------------
+How to build:
+-------------
+
+REFER https://oic-review.01.org/gerrit for more details on getting oic-resource repo.
+If the code is not cloned:
+Clone the oic-resource repo using this command: git clone oic:oic-resource
+
+NOTE: If the repo is already cloned, use 'git pull' inside oic-resource folder to get the
+latest code.
+
+In repo oic-resource, root folder consists of 'resource' folder. Inside OIC folder there
+is a Makefile.
+
+Inside oic-resource directory, use 'make'to build the entire OIC code. This would build the C++ SDK,
+core(i.e base) and samples.
+
+Use 'make BUILD=debug' to build the entire OIC code in debug mode. This would build the C++ SDK,
+core(i.e base) and samples.

+Existing subscribePresence API has been overloaded with a resource type parameter.
+Client can now subscribe presence with interested resource type.
+This release also supports multicast presence subscription.
+
+Available subscription options are:
+
+Unicast presence subscription without resource type.
+Multicast presence subscription without resource type.
+Unicast presence subscription with resource type.
+Multicast presence subscription with resource type.
+
+------------
+Other Notes:
+------------
+
+Maximum length of URI supported is 64 bytes (sent from the client)
+Maximum length of query supported is 64 bytes (sent from the client)
+Maximum length of request and response from server for Ardunio is is 256 bytes
+Maximum length of request and response from server for non-Ardunio is is 1024 bytes
+
+OIC base supports Arduino WiFi shield.
+This support has been tested with Arduino Mega 2560 and with Arduino 1.0.5 WiFi library.
+Please refer to oic-resource/csdk/README file for building OIC base with WiFi support.
+
+Security:
+1. OCStack is compiled with security only if a valid libtinydtls.a is available
+under oic-resource/resource/csdk/tinydtls directory.
+2. Currently, security credentials for resource and client are hard-coded in the stack source files.
+3. Currently, tinyDTLS does not support establishing new associations with existing parameters.
+Due to this limitation, if the client application is re-started and attempts to create a new DTLS
+session with an existing server, tinyDTLS server rejects the request.
+4. Security is NOT supported for Arduino platform.
+
+Known issues:
+
+1. When observation is used, server shutdown causes an error.
+
+Active discovery-
+1. In case of unicast presence with rt, only one rt is permitted per IP address for
+subscribePresence. If multiple subscriptions are done, only first subscribePresence’s rt is used.
+2. For multicast presence, server shutdown (ungraceful) scenario is not notified to the client,
+but graceful shutdowns are notified.

+
+What is new?
+
+--------------------------------------------
+Class OCPlatform (Header file: OCPlatform.h)
+--------------------------------------------
+
+OCPlatform has new set of overloaded APIs for QoS support
+- findResource
+- notifyAllObservers
+- notifyListOfObservers
+
+These overloaded APIs allow app developers to specify QoS level. Please see 'Other notes' section for
+details in QoS.
+
+--------------------------------------------
+Class OCResource (Header file: OCResource.h)
+--------------------------------------------
+
+OCResource has new set of overloaded APIs for QoS support
+- get
+- put
+- post
+- observe
+- cancelObserve
+- deleteResource
+
+These overloaded APIs allow app developers to specify QoS level. Please see 'Other notes' section for
+details in QoS.
+
+*****************
+deleteResource API
+*****************
+
+This new API allows the client to perform Delete operations on a resource.
+
+NOTE: This applies to client side functionality.
+
+*****************
+setHeaderOptions API
+*****************
+
+This new API allows the client to set header options.
+
+NOTE: Once headers options are set, it will be applicable to GET, PUT and observe request.
+NOTE: This applies to client side functionality.
+
+*****************
+unsetHeaderOptions API
+*****************
+
+This new API allows the client to unset header options.
+NOTE: This applies to client side functionality.
+
+--------------------------------------------
+Class OCHeaderOption (Header file: OCHeaderOption.h)
+--------------------------------------------
+OCHeaderOption class allows to create instances which comprises optionID
+and optionData as members. These are used in setting Header options.
+After creating instances of OCHeaderOptions, setHeaderOptions API
+(in OCResource.h) can be used to set header Options.
+NOTE: HeaderOptionID is an unsigned integer value which MUST be within
+range of 2048 to 3000 inclusive of lower and upper bound.
+HeaderOptions instance creation fails if above condition is not satisfied.
+
+Refer 'Other Notes' section for more details on Header options.

+
+Bug fixes:
+IOT-58
+
+QoS
+-QoSlevels support LowQoS, MidQoS, HighQoS and NaQoS.
+-LowQoS and MidQoS are translated to non-conifirmable in CoAP.
+-HighQoS translated to confirmable in CoAP.
+-NaQoS allows the base to choose appropriate QoS level. It defaults to LowQoS.
+-In observe notifications, it uses the same QoS level the observer used in the observe registration request.
+
+On graceful server shutdown:
+-Client-observers will now be notified when the resource they are observing is being deleted.
+-Also applies for presence notifications.
+
+Header options support:
+- This support provides the client to send custom header options to server and vice-versa.
+- Server handles the header options received from the clients in the entity handler.
+- Header options sent from the server are received in get, put, post, delete, observe callbacks.
+- Sample shown in fridge samples.
+
+Entity handler modification:
+-Returns OCEntityHandlerResult instead of void.
+-OCEntityHandlerResult return types are OC_EH_RESOURCE_CREATED and OC_EH_RESOURCE_DELETED.
+
+Exception handling:
+-This release includes enhancements in exception handling.

+OIC base now supports Arduino WiFi shield.
+This support has been tested with Arduino Mega 2560 and with Arduino 1.0.5 WiFi library.
+Please refer to oic-resource/csdk/README file for building OIC base with WiFi support.
+
+As part of this release, clean up items included are:
+Removal of header files, source files, folders which are not used as part of build. OCLib
+More typedefs for clarity and readability.
+More comments in sample files.
+
+Bug fixes:
+IOT-25
+IOT-31
+IOT-45
+IOT-48
+Minor bugs fixed
+Memory leak issues fixed
+
+Presence notifications:
+OCStartPresence and OCStopPresence are updated so that if can be called when server comes online and offline respectively.
+Notifications will now be sent when a resource is modified or deleted.
+Now notifications to the app are sent only when there is a change in nonce.
+
+Observe notifications:
+When using OCNotifyListOfObservers, the memory for obsIdList and notificationJSONPayload is managed by the entity handler invoking the API.
+The maximum size of the notification is 1015 bytes for non-Arduino platforms and 247 bytes for Arduino platforms.
+
+Server sample (oic-resource/examples/simpleserver.cpp) has been updated to showcase invoking either notifyAllObservers or notifyListOfObservers.
+Once the samples are built (see 'How to build' section below), if notifyAllObservers needs to be used, the app can be run as
+'./simpleserver 0"
+Note: './simpleserver' without any input parameter will also invoke notifyAllObservers.
+
+If notifyListOfObservers needs to be used, the app can be run as
+'./simpleserver 1'
+
+Improvements:
+OCRepresentation provides simpler interface to setValue and getValue from the apps. Apps do not need to use AttributeMap in OCRepresentation.
+OCRepresentation now supports serialization/deserilization for primitive (numbers, booleans and strings), so app need not directly have to
+deal with strings.
+
+Known issues:
+More than one presence notification is sent out when a new resource is created instead of one notification (IOT-49)
+When OCNotifyListOfObservers is invoked with a list of observer IDs and if any of observer ID does not exist in the base, flow continues processing
+other observe IDs.

+*****************
+OCSetDefaultDeviceEntityHandler API
+*****************
+
+This new API allows the server side app developer to provide a default device entity handler.
+If server receives a request in which the resource URI does not match any of the existing
+resource URIs, base will invoke this default entity handler. It is app developer's responsibility
+to handle the implementation of default device entity handler accordingly.
+If the default device entity handler is not configured and the URI in the request does not match
+any of the existing resource URIs, server will return OC_STACK_NO_RESOURCE.
+
+NOTE: This applies to server side functionality only.
+
+------------
+Other Notes:
+------------
+
+Security model is still open.
+APIs have OCStackResult as return type. This is will indicate success or failure for the API operation.
+
+Maximum length of URI supported is 64 bytes (sent from the client)
+Maximum length of query supported is 64 bytes (sent from the client)
+Maximum length of request and response from server for Ardunio is is 256 bytes
+Maximum length of request and response from server for non-Ardunio is is 1024 bytes
+
+OIC base now supports Arduino WiFi shield.
+This support has been tested with Arduino Mega 2560 and with Arduino 1.0.5 WiFi library.
+Please refer to oic-resource/csdk/README file for building OIC base with WiFi support.
+
+Bug fixes:
+IOT-36
+Minor bugs fixed
+
+Known issues:
+1. POST operation does not create new resources
+2. Header options from client to server and vice-versa is not available.
+3. Setting CON/NON-CON option is possible only during initialization configuration.
+-------------
+How to build:
+-------------
+
+REFER https://oic-review.01.org/gerrit for more details on getting oic-resource repo.
+If the code is not cloned:
+Clone the oic-resource repo using this command: git clone oic:oic-resource
+Clone the oic-utilities repo using this command: git clone oic:oic-utilities
+
+NOTE: If the repo is already cloned, use 'git pull' inside oic-resource folder to get the latest code.
+
+In repo oic-core, root folder ccf-opensource consists of 'OIC' folder. Inside OIC folder there is a Makefile.
+
+Before building, make sure to have contents from oic-utilities repo at the folder level where oic-resource is.
+
+Inside oic-resource directory, use 'make'to build the entire OIC code. This would build the C++ SDK, core(i.e base) and samples.
+
+Use 'make BUILD=debug' to build the entire OIC code in debug mode. This would build the C++ SDK, core(i.e base) and samples. All the executables for debug build
+are in 'oic-resource/debug'.
+
+--------
+Samples:
+--------
+
+New Samples added:
+oic-resource/examples/garageclient.cpp
+oic-resource/examples/garageserver.cpp
+
+Garage samples provide usage of OCRepresentation, get/set attribute values
+
+oic-resource/examples/fridgeclient.cpp
+oic-resource/examples/fridgeserver.cpp
+
+Fridge samples provide usage of constructResourceObject API, std bind (for mapping request and responses) and default
+device entity handler
+
+After building the code in oic-resource, executables for samples are in directory named 'oic-resource/samples/release'.
+After building the code in oic-resource, executables are in directory named 'oic-resource/release'.
+A sample for hosting a resource on a server and a sample for client for discovering resources are provided in the following paths:
+
+Server sample location: oic-resource/examples/simpleserver.cpp
+Client sample location: oic-resource/examples/simpleclient.cpp
+Server and client mode (mode type both) location: oic-resource/examples/simpleclientserver.cpp
+
+Sample with basic presence feature for server side: oic-resource/examples/presenceserver.cpp
+Sample with basic presence feature for client side: oic-resource/examples/presenceclient.cpp

+// NOTICE - Transition to SCONS
+//---------------------------------------------------------------------
+
+The IoTivity build system is transitioning to SCONS. Although the
+makefiles are still available (until v1.0) and some developers are
+still using them, they are currently no longer supported. To learn more
+about building using SCONS see Readme.scons.txt in the repository root
+directory. The build steps used in continuous integration can be found
+in auto_build.sh which is also in the the repository root directory.
+
+//---------------------------------------------------------------------
+
+tests.cpp contains unittests for C++ APIs. It uses Google Test for the unit
+tests. Note that the unit tests are only to test the functionality of OCApi.h.
+It is not a system or end-to-end test.
+
+Unit Test Requirements:
+
+1. To run the unit test, first build the unit tests with the following command
+ from <oic-resource>:
+
+ make -f buildScript.mk linux_ub_unittests
+
+2. Run the unit test by issuing the following command from <oic-resource>:
+
+ ./unittests/tests

+== How to write IoTivity build script ==
+
+IoTivity projects are built with Scons. Scons is a cross-platform build tool,
+it's quite similar to 'make'. 'SConstruct' is the entrance of scons build, it's
+equivalent to 'Makefile' to 'make'.
+
+This document only a brief reference. Detail about how to write scons script,
+please refer to:
+ http://www.scons.org/doc/production/HTML/scons-user.html#
+
+== Background: How to control source code compiling ==
+
+Environment is a base conception of Scons. An environment is a collection of
+values that can affect how a program is built.
+
+e.g. There is a C file named hello.c, enter the following into a file named
+SConstruct:
+ env = Environment()
+ env.Program('H', 'hello.c')
+
+When run Scons in console, following will be executed:
+cc -o hello.o -c hello.c
+cc -o H hello.o
+
+If you would like keep debug information in the binary, '-g' flag should be added
+when build the source code. To do this, append a C compiler flags as following:
+ env = Environment()
+ env.AppendUnique(CFLAGS = ['-g'])
+ env.Program('H', 'hello.c')
+
+When run Scons, following will be executed:
+cc -o hello.o -c -g hello.c
+cc -o H hello.o
+
+In above example, 'CFLAGS' is changed. Following list the frequently used keys:
+
+CFLAGS: General options that are passed to the C compiler
+CCFLAGS: General options that are passed to the C & C++ compiler
+CXXFLAGS: General options that are passed to the C++ compiler
+CPPPATH: The directories that the preprocessor will search for include headers.
+CPPDEFINES: Platform independent specification of C preprocessor definitions.
+
+Note: CPPPATH and CPPDEFINES is common for all compiler. But others are
+compiler specific, when change the key value, it may requried to specify the
+target platform(actually the compiler).
+
+e.g.
+ env.AppendUnique(CPPPATH = ['.', 'include'])
+ env.AppendUnique(CPPDEFINES = ['NDEBUG', 'VER_TEST'])
+Above two lines are fine for all target platform. but below line:
+ env.AppenUnique(CXXFLAGS = ['-g'])
+is only fine for gcc compiler, as '-g' is a gcc flag, other compiler may don't
+understand it. so it may should be:
+ if target_os not in ['windows', 'winrt']:
+ env.AppenUnique(CXXFLAGS = ['-g'])
+
+Still take the hello.c as example. Assume hello.h is in ./include/ directory,
+#include "hello.h"
+int main(int argc, char** argv)
+{
+#ifdef LANG_FR
+ printf("Bonjour\n");
+#else
+ printf("Hello\n");
+#endif
+}
+
+The Scons configure file should as following:
+ env = Environment()
+ env.AppendUnique(CFLAGS = ['-g'])
+ env.AppendUnique(CPPPATH = ['include'])
+ env.AppendUnique(CPPDEFINES = ['LANG_FR'])
+ env.Program('H', 'hello.c')
+
+When run Scons, following will be executed:
+cc -o hello.o -c -g -Iinclude -DLANG_FR hello.c
+cc -o H hello.o
+
+=== Get extra information ===
+
+In above example, 'target_os' is used. How to get it?
+
+User can build IoTivity project on Linux / Windows / MAC OSX for various
+targets(Linux, Tizen, Android, Arduino, Windows, MAC OSX, IOS ...). Most
+platform specific configures have been done in the common scripts which are in
+build_common. The common scripts prepare an environment named 'env' with
+target platform specific configuration.
+
+When write IoTivity project build script, you can get this environment as
+following:
+ Import('env')
+
+You can use 'env' directly after import it. You can also clone a new environment
+and update its keys.
+
+ new_env1 = Clone('env')
+ new_env2 = Clone('env')
+ new_env1.AppendUnqiue(xxx = [...])
+ new_env2.AppendUnqiue(xxx = [...])
+
+The 'env' environment contains platform specific configuration, besides, there is
+some common information. You can get the information with following line:
+ env.get('XXX')
+or
+ env['XXX']
+
+XXX is the information name, below are the extra information added by IoTivity
+common scrirpts:
+BUILD_DIR: the path of the build directory, all output are in this directory
+SRC_DIR: the path of the top directory of the source code
+OIC_UTILS: the path of oic-utilities project
+RELEASE: build type, boolean. True - release build, False - debug build
+TARGET_OS: the name of the target OS. The possible value depends on the host
+ platform. Bellow is the list of host and possible target OS. (darwin means
+ MAC OSX)
+ linux: linux / android / arduino / tizen
+(the line means on Linux, you can build the project for Linux/Android/Arduino/Tizen)
+ windows: windows / winrt / android / arduino
+ darwin: darwin / ios / android / arduino
+
+TARGET_ARCH: the target CPU arch. Its possible value depend on the target OS.
+ Bellow list the target OS and allowed CPU architecture.
+ linux: x86 / x86_64 / arm / arm64
+(above line means if the target OS is Linux, the CPU arch can be x86/x86_64/arm/arm64)
+ android: x86 / x86_64 / armeabi / armeabi-v7a / armeabi-v7a-hard / arm64-v8a
+ windows: x86 / amd64 / arm
+ winrt: arm
+ darwin: i386 / x86_64
+ ios: i386 / x86_64 / armv7 / armv7s / arm64,
+ arduino: avr / arm
+
+=== Extra functions ===
+
+For convenience, in the common scripts, some extra functions are added.
+
+PrintTargets(): print all targets in the help information.
+AppendTarget(target): add 'target' into targets list, when use PrintTargets,
+ the 'target' will be print.
+InstallTarget(files, name): it takes the same action as AppendTarget, besides,
+ it installs the 'files' to BUILD_DIR.
+
+Following functions are only for Arduino:
+ImportLib(lib): Arduino IDE includes many libraries. By default, no library is
+compiled. If your project use some libraries, you can import the library by
+this function. 'lib' is the name of the library to import. The 'include' path
+will be auto added to the environment and the library will be built and linked
+into the final binary.
+
+CreateBin('bin', src): For Arduino, after build the program, it's required to
+be converted into specific format (e.g .hex). This function will genearate the
+required .hex (and .eep if target arch is avr) file.
+
+UploadHelp(): For different board, the upload command line is different, this
+function print the recommended upload command line. You can see the recommended
+upload command line in the help information(the output of command "scons
+[options] -h")
+
+==== Scripts Hierarchy ====
+
+Scons provides a function 'SConscript(scripts, [exports, variant_dir, duplicate])'
+It tells scons to execute one or more subsidiary configuration files(A script,
+usually named SConscript). Take below project hierarchy as example to show how
+to organize the scripts.
+
+ prj
+ |-------prj_1
+ | |--------sub_prj_11
+ | |--------sub_prj_..
+ | |--------sub_prj_1n
+ |-------prj_2
+ |
+ | ... ...
+ |
+ |-------prj_n
+
+As above project hierarchy, in 'SConstruct' file in the 'prj' directory, there
+should include some lines like these:
+
+#Please change this part according to the organization of your projects.
+#Note: To make the output is in build_dir, the path of the scripts should
+#be relevant to build_dir
+SConscript(build_dir + 'prj_1/SConscript')
+SConscript(build_dir + 'prj_2/SConscript')
+... ...
+SConscript(build_dir + 'prj_n/SConscript')
+
+
+It's the same, in the 'prj_1/SConscript', there should include lines like
+these:
+SConscript('sub_prj_11/SConscript')
+... ...
+SConscript('sub_prj_1n/SConscript')
+
+The path is relevant to 'prj_1/SConscript'. You can also use the full path
+build_dir + 'prj_1/sub_prj_1x/SConscript', but it's not recommended.
+
+Above just to show a recommended way to manage subsidiary scripts. You don't
+need restrictly follow it.
+
+==== The content of a typical script ====
+
+After run the scripts in build_common (usally it's done at the beginning of
+SConstruct), an global environment 'env' is exported, 'env' has include the
+default configuration of the target OS and arch. 'env' is used in all projects,
+should avoid to change its keys. To avoid change 'env', usually clone 'env' and
+update it accroding to the requirement of cuurent sub project. Then specify the
+target(usually binary) to build.
+
+Below is an example:
+ # import the global enviroment 'env'
+ Import('env')
+
+ # Clone a new enviroment from 'env'
+ new_env = env.Clone()
+
+ # Update the new enviroment, usally include add header file paths,
+ # library path, libs to link and other compiler flags. This part is
+ # optional. If not present, the default configuration will be used
+ new_env.AppeneUnique(xxx = [ .... ])
+
+ # Specify the target(application, library, object or others) to build
+ ts = new_env.Program('progam_name', [source_list])
+
+ # Install the target (optional)
+ # If it's an important library or daemon to be published
+ new_env.InstallTarget(ts, 'target_name')
+or
+ # If is't examples or test program or others will not be published
+ new_env.Alias('target_name', ts)
+ new_env.AppendTarget('target_name')
+
+==== Tips ====
+1. library order: if A lib use B lib, both A and B are linked to target T, the
+ when specify libraries, A should in front of B, otherwise there may be link
+ error.
+2. On android:
+ (1)'pthread' is in libc. So don't use '-lpthread' for android
+ (2)By default 'rtti' and 'exception' is disabled, to enable it, you need
+ add flags '-frtti' and '-fexceptions'
+ (3)If STL is used, need link 'gnustl_static' library

+Readme file for Arduino Time Library
+
+Time is a library that provides timekeeping functionality for Arduino.
+
+The code is derived from the Playground DateTime library but is updated
+to provide an API that is more flexable and easier to use.
+
+A primary goal was to enable date and time functionality that can be used with
+a variety of external time sources with minimum differences required in sketch logic.
+
+Example sketches illustrate how similar sketch code can be used with: a Real Time Clock,
+internet NTP time service, GPS time data, and Serial time messages from a computer
+for time synchronization.
+
+The functions available in the library include:
+
+hour(); // the hour now (0-23)
+minute(); // the minute now (0-59)
+second(); // the second now (0-59)
+day(); // the day now (1-31)
+weekday(); // day of the week, Sunday is day 0
+month(); // the month now (1-12)
+year(); // the full four digit year: (2009, 2010 etc)
+
+there are also functions to return the hour in 12 hour format
+hourFormat12(); // the hour now in 12 hour format
+isAM(); // returns true if time now is AM
+isPM(); // returns true if time now is PM
+
+now(); // returns the current time as seconds since Jan 1 1970
+
+The time and date functions can take an optional parameter for the time. This prevents
+errors if the time rolls over between elements. For example, if a new minute begins
+between getting the minute and second, the values will be inconsistent. Using the
+following functions eliminates this probglem
+ time_t t = now(); // store the current time in time variable t
+ hour(t); // returns the hour for the given time t
+ minute(t); // returns the minute for the given time t
+ second(t); // returns the second for the given time t
+ day(t); // the day for the given time t
+ weekday(t); // day of the week for the given time t
+ month(t); // the month for the given time t
+ year(t); // the year for the given time t
+
+
+Functions for managing the timer services are:
+setTime(t); // set the system time to the give time t
+setTime(hr,min,sec,day,mnth,yr); // alternative to above, yr is 2 or 4 digit yr (2010 or 10 sets year to 2010)
+adjustTime(adjustment); // adjust system time by adding the adjustment value
+
+timeStatus(); // indicates if time has been set and recently synchronized
+ // returns one of the following enumerations:
+ timeNotSet // the time has never been set, the clock started at Jan 1 1970
+ timeNeedsSync // the time had been set but a sync attempt did not succeed
+ timeSet // the time is set and is synced
+Time and Date values are not valid if the status is timeNotSet. Otherwise values can be used but
+the returned time may have drifted if the status is timeNeedsSync.
+
+setSyncProvider(getTimeFunction); // set the external time provider
+setSyncInterval(interval); // set the number of seconds between re-sync
+
+
+There are many convenience macros in the time.h file for time constants and conversion of time units.
+
+To use the library, copy the download to the Library directory.
+
+The Time directory contains the Time library and some example sketches
+illustrating how the library can be used with various time sources:
+
+- TimeSerial.pde shows Arduino as a clock without external hardware.
+ It is synchronized by time messages sent over the serial port.
+ A companion Processing sketch will automatically provide these messages
+ if it is running and connected to the Arduino serial port.
+
+- TimeSerialDateStrings.pde adds day and month name strings to the sketch above
+ Short (3 character) and long strings are available to print the days of
+ the week and names of the months.
+
+- TimeRTC uses a DS1307 real time clock to provide time synchronization.
+ A basic RTC library named DS1307RTC is included in the download.
+ To run this sketch the DS1307RTC library must be installed.
+
+- TimeRTCSet is similar to the above and adds the ability to set the Real Time Clock
+
+- TimeRTCLog demonstrates how to calculate the difference between times.
+ It is a vary simple logger application that monitors events on digtial pins
+ and prints (to the serial port) the time of an event and the time period since the previous event.
+
+- TimeNTP uses the Arduino Ethernet shield to access time using the internet NTP time service.
+ The NTP protocol uses UDP and the UdpBytewise library is required, see:
+ http://bitbucket.org/bjoern/arduino_osc/src/14667490521f/libraries/Ethernet/
+
+- TimeGPS gets time from a GPS
+ This requires the TinyGPS library from Mikal Hart:
+ http://arduiniana.org/libraries/TinyGPS
+
+Differences between this code and the playground DateTime library
+although the Time library is based on the DateTime codebase, the API has changed.
+Changes in the Time library API:
+- time elements are functions returning int (they are variables in DateTime)
+- Years start from 1970
+- days of the week and months start from 1 (they start from 0 in DateTime)
+- DateStrings do not require a seperate library
+- time elements can be accessed non-atomically (in DateTime they are always atomic)
+- function added to automatically sync time with extrnal source
+- localTime and maketime parameters changed, localTime renamed to breakTime
+
+Technical notes:
+
+Internal system time is based on the standard Unix time_t.
+The value is the number of seconds since Jan 1 1970.
+System time begins at zero when the sketch starts.
+
+The internal time can be automatically synchronized at regular intervals to an external time source.
+This is enabled by calling the setSyncProvider(provider) function - the provider argument is
+the address of a function that returns the current time as a time_t.
+See the sketches in the examples directory for usage.
+
+The default interval for re-syncing the time is 5 minutes but can be changed by calling the
+setSyncInterval( interval) method to set the number of seconds between re-sync attempts.
+
+The Time library defines a structure for holding time elements that is a compact version of the C tm structure.
+All the members of the Arduino tm structure are bytes and the year is offset from 1970.
+Convenience macros provide conversion to and from the Arduino format.
+
+Low level functions to convert between system time and individual time elements are provided:
+ breakTime( time, &tm); // break time_t into elements stored in tm struct
+ makeTime( &tm); // return time_t from elements stored in tm struct
+
+The DS1307RTC library included in the download provides an example of how a time provider
+can use the low level functions to interface with the Time library.

+Followings should be done befor building Arudno applications
+
+1. Applications on arduino conform the Iotivity Base released on 22-Aug-2014.
+ (Ver. 22th Aug(oic-resource: commit: cdeeed62bd9b11beb2cdd340168e766088c18dac [cdeeed6]))
+
+ For successful execution, you have to copy the file, local.properties, into the following pathes:
+ - oic-resource/csdk/
+ - oic-resource/csdk/libcoap-4.1.1
+
+
+2. Time.c, Time.h should be copied in your machine and they should be refered in the Makefile as followings
+
+ Makefile path: / oic-resource / csdk / libcoap-4.1.1 / makefile
+
+ path to be modified:
+
+ - INCD_ARD_TIME = -I$(ARDUINO_DIR)/libraries/Time ---> for Time.h
+ - SDIR_ARD_TIME = $(ARDUINO_DIR)/libraries/Time ---> for Time.c

+C-Pluff (0.1.3) alpha
+
+ * Fixed a bug in Windows multi-threading support. Mutex was not
+ actually locked in cpi_lock_mutex.
+ * Fixed a bug in libltdl support. libltdl was not being initialized.
+ * Made cpfile example application compatible with Windows.
+ * Added Windows packaging using cross-compilation on Debian.
+ * Added Microsoft Visual C build environment for examples.
+ * Small improvements to installation documentation and packaging.
+ * Support Expat 1.95.1 and GnuWin32 version of libintl.
+ * Tools: Delegate binding of gettext domain to the library.
+ * Moved documentation sources out from C source directories.
+
+ -- Johannes Lehtinen <johannes.lehtinen@iki.fi> Fri, 6 Apr 2007 15:36:30 +0300
+
+C-Pluff (0.1.2) alpha
+
+ * Removed a flawed check of whether dynamically resolved symbols are
+ in use when a plug-in is being stopped.
+ * Fixed a bug in libcpluff: When stopping plug-in dependency chains,
+ first call stop function of every plug-in in the chain and then call
+ destroy functions. This makes it possible to do safe two-phase cleanup.
+ Previously the destroy function of a plug-in was called immediately
+ after the stop function of the corresponding plug-in.
+ * Make plug-in dependency loop log message an informational message
+ and not a warning.
+ * Minor documentation changes and corrections.
+ * Build, install and distribute internationalization support files.
+ * Link with libintl if internationalization support needs it.
+ * Unified message string structure and wording.
+ * Include finnish translation (to test internationalization).
+ * Fixed some installation/packaging problems.
+ * Install documentation as part of installation.
+ * Install example source code as part of installation.
+ * Include optional stand-alone build system for example code.
+ * Respect DESTDIR during installation.
+
+ -- Johannes Lehtinen <johannes.lehtinen@iki.fi> Wed, 28 Mar 2007 10:24:31 +0300
+
+C-Pluff (0.1.1) alpha
+
+ * More complete documentation.
+ * Added an example of extensible application (cpfile).
+ * Fixed bug in cpluff-loader: Use empty string for the first argument
+ instead of NULL pointer.
+ * Fixed bug in cp_get_extensions_info: Overwrote memory when
+ returning extensions for a specific extension point.
+ * Fixed bug in plug-in uninstallation: Accessed freed memory when
+ uninstalling a plug-in.
+ * Do not warn about unknown attributes of an extension element
+ because they might be extension point specific data.
+ * Build reference documentation in build directory.
+ * Added a test for inter-plugin symbol usage.

+INSTALLING C-PLUFF
+==================
+
+These are instructions for building and installing the C-Pluff framework
+implementation using the source code distribution. Precompiled binaries
+are available for some platforms at the download page
+
+ http://www.c-pluff.org/download
+
+For help on building C-Pluff based applications, see the examples in the
+examples directory.
+
+
+Prerequisites
+-------------
+
+To build C-Pluff, you need to have following prerequisites installed:
+
+ - a C library supporting POSIX dlopen
+ (for example, GNU C library)
+ or
+ GNU Libtool libltdl library
+ (http://www.gnu.org/software/libtool/)
+
+ - Expat XML Parser library for C
+ (http://expat.sourceforge.net/)
+
+Following components are optional and are used if they are installed:
+
+ - GNU gettext libintl library for localization
+ (http://www.gnu.org/software/gettext/gettext.html)
+
+ - GNU Readline Library for enhanced command line
+ (http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html)
+
+
+Building
+--------
+
+To build C-Pluff, follow the usual autotools procedure:
+
+ Building in the source directory:
+ ./configure
+ make
+
+ Building in a separate build directory:
+ cd BUILD_DIR
+ SOURCE_DIR/configure
+ make
+
+You can specify the installation prefix (for example, /usr or /usr/local)
+when running the configure script.
+
+ ./configure --prefix=/usr
+
+The default installation prefix is /usr/local. More help on available
+configuration options is available using the --help option.
+
+ ./configure --help
+
+
+Installation
+------------
+
+You can install the library, header files, utilities, documentation and
+examples by making target install:
+
+ make install
+
+If installing to system directories you have to do this as root.
+
+Additionally, you can specify a directory to be used in place of the
+root directory during installation. This is typically used to create
+binary packages.
+
+ make DESTDIR=/tmp/installation install
+
+
+Known good build platforms
+--------------------------
+
+C-Pluff is known to compile cleanly on following combinations:
+
+ - Native Linux build
+ - GCC 4.1.2
+ - GNU C library 2.3.6
+ - Expat 1.95.8
+
+ - Cross compilation for Windows on Linux
+ - MinGW Runtime 3.9
+ - MinGW binutils 2.16.91
+ - MinGW 3.4.5
+ - Expat 2.0.0 (or 1.95.8 or 1.95.1)
+ - GNU Libtool libltdl 1.5.22
+ - GNU Gettext 0.16.1 (or 0.14.4)

+KNOWN ISSUES
+============
+
+
+cpfile does not rezognize directories when compiled with MinGW
+--------------------------------------------------------------
+
+(Thu, 5 Apr 2007 06:58:32 +0300)
+
+MinGW cross-compiled version of cpfile example application does not
+recognize special files (directories) although the support is in place.
+Reason for the problem is not known. The related source code is in
+examples/cpfile/plugins/special/special.c. The following test code
+works fine when cross-compiled with MinGW.
+
+- clip -
+#include <sys/types.h>
+#include <sys/stat.h>
+#include <unistd.h>
+#include <stdio.h>
+#include <windows.h>
+
+int main(int argc, char *argv[]) {
+ int i;
+
+ for (i = 1; i < argc; i++) {
+ struct stat s;
+
+ printf("%s: ", argv[i]);
+ if (stat(argv[i], &s)) {
+ fflush(stdout);
+ perror("stat failed");
+ } else {
+ if (S_ISDIR(s.st_mode)) {
+ fputs("is directory\n", stdout);
+ } else {
+ fputs("is not directory\n", stdout);
+ }
+ }
+ }
+ return 0;

+ interprets characters like ' ', '\t', '\\', '"' (but not '<' and '>') in a

+ - Space and tab are interpreted as delimiters. They are not treated as
+ delimiters if they are surrounded by double quotes: "...".
+ - Unescaped double quotes are removed from the input. Their only effect is
+ that within double quotes, space and tab are treated like normal
+ characters.
+ - Backslashes not followed by double quotes are not special.
+ - But 2*n+1 backslashes followed by a double quote become
+ n backslashes followed by a double quote (n >= 0):
+ \" -> "
+ \\\" -> \"

+
+ <h2 id="overview">Overview</h2>
+ <p>
+ C-Pluff is a plug-in framework for C programs.
+ It has been strongly inspired by the Java plug-in framework in
+ <a href="http://www.eclipse.org/">Eclipse</a>. C-Pluff focuses on
+ providing core services for plug-in interaction and plug-in
+ management. It aims to be platform neutral and supports dynamic
+ changes to plug-in configuration without stopping the whole
+ application or framework. It does not yet provide special facilities
+ for distribution such as signed plug-in packages or remote plug-in
+ repositories but it is possible to build such features on top of the
+ current framework.
+ </p>
+ <p>
+ The current C-Pluff implementation and documentation is very much
+ work in progress so it should be considered early alpha stage software.
+ I will be updating the documentation and source distribution on this
+ site as I proceed with documentation and implementation.
+ If you are interested in C-Pluff, take a look at
+ <a href="reference/c-api/index.html">reference documentation</a>,
+ join <a href="http://www.c-pluff.org/lists">mailing lists</a> or
+ <a href="http://www.c-pluff.org/download">download it</a>. You can also send
+ feedback, ideas and thoughts about such platform directly to the
+ <a href="mailto:johannes.lehtinen@iki.fi">author</a>.
+ </p>
+
+ <h2 id="structure">Architecture</h2>
+ <p>
+ The plug-in architecture supported by C-Pluff is presented in the
+ following figure. There is a thin main program controlling the plug-in
+ framework. The main program is responsible for initializing and setting
+ up the plug-in environment. Most of the application logic is contained in
+ plug-ins which are independent components and can be developed and
+ distributed separately. Plug-ins integrate with each other by providing
+ extension points and extensions. An extension point is a point into which
+ other plug-ins can attach extensions. An extension can be just
+ information, expressed in XML format, or the plug-in may also provide
+ program logic as part of the plug-in runtime library. The framework
+ provides services for accessing extensions and for managing plug-in
+ dependencies.

Most of the application logic is contained in plug-ins which are independent components and can be developed and distributed separately.

+Extensions</a></h2>
+The idea behind extension points and extensions is that the extensibility is not limited only to few fixed plug-in types supported by the core application. Although the core plug-ins typically define the extension points for the core application logic, it is possible for any plug-in to specify additional extension points.<p>
+For example, let us assume that we are developing an extensible text editor. One extension point defined by core editor plug-in could be auto-completion extension point. A plug-in providing basic Java source code support could provide an extension for auto-completing Java code. Now, while this extension could do basic auto-completion of plain Java code, it is customary that Java source code also includes embedded documentation, such as JavaDoc comments and tags, or annotations, such as XDoclet tags, as part of doc comments. Instead of trying to support all known tags and their semantics, the plug-in providing basic Java support could define another extension point for additional plug-ins that know how to perform auto-completion of different kind of tags in doc comments. This way the extensibility of the application is not limited to the extension points defined by the core application but the plug-ins can incrementally increase the extensibility of the application. <hr size="1">

+<h1><a class="anchor" name="cMainProgram">Main program</a></h1><h2><a class="anchor" name="cMainProgramOverview">
+Overview</a></h2>
+The main program is the part of executable that is located outside the plug-in framework. The main program is responsible for setting up the plug-in framework and for loading the desired set of <a class="el" href="plugin.html">plug-ins</a>. The main program should preferably be very thin, a mere plug-in loader, because it can not fully participate in plug-in interaction. C-Pluff distribution provides a plug-in loader, cpluff-loader, which can be used as a generic main program for arbitrary plug-in collections.<h2><a class="anchor" name="cMainProgramResponsibilities">
+Responsibilities</a></h2>
+The main program has several responsibilities:<p>
+<ul>
+<li><a class="el" href="cMainProgram.html#cMainProgramInitFramework">initializing the plug-in framework</a></li><li><a class="el" href="cMainProgram.html#cMainProgramCreateContext">creating a plug-in context</a></li><li><a class="el" href="cMainProgram.html#cMainProgramLoad">loading plug-ins</a></li><li><a class="el" href="cMainProgram.html#cMainProgramExec">controlling plug-in execution</a></li><li><a class="el" href="cMainProgram.html#cMainProgramChange">changing plug-in configuration</a> (opt.)</li><li><a class="el" href="cMainProgram.html#cMainProgramDestroyFramework">destroying the plug-in framework</a></li></ul>
+<h3><a class="anchor" name="cMainProgramInitFramework">
+Initializing the plug-in framework</a></h3>
+Plug-in framework, or the C-Pluff library, must be initialized before its services can be used. Initialization is not a thread-safe operation and should generally be done by the main program before any additional plug-in framework accessing threads are started. Initialization is done by calling <a class="el" href="group__cFuncsInit.html#gc72ffd50777c3e898dae661c67b04ba9">cp_init</a>. Additionally, the main program can use <a class="el" href="group__cFuncsInit.html#gc794f61edbd896327fabddad2b3d2fd5">cp_set_fatal_error_handler</a> to register a function that is called when a fatal error occurs. A fatal error is one that prevents the framework from continuing operation. For example, errors in operating system locking operations and a NULL pointer being passed as an argument which is expected to have a non-NULL value are fatal erors.<p>
+Here is an example of possible initialization code.<p>

+Creating a plug-in context</a></h3>
+A plug-in context represents the co-operation environment of a set of plug-ins from the perspective of a particular participating plug-in or the perspective of the main program. From main program perspective, a plug-in context is a container for a set of plug-ins. A plug-in can interact with other plug-ins in the same container.<p>
+An extensible application can have more than one plug-in container but usually one container should suffice. Due to the nature of C programs, plug-ins deployed to different containers are not very well insulated from each other. For example, global variables provided by a plug-in in one container are visible to all plug-ins in all containers. Also, by placing all plug-ins in the same container they can more efficiently share common base components which themselves might provide extensibility.<p>
+A main program creates a plug-in context, to be used as a container for plugins, using <a class="el" href="group__cFuncsContext.html#g7d239c4fc07cf7d3095a20900444ad62">cp_create_context</a>.<p>

+Loading plug-ins</a></h3>
+An extensible application is made of plug-ins that can be added and removed dynamically. The plug-ins are loaded by the main program using the services provided by the framework. The framework provides couple of alternative ways of loading plug-ins.<p>
+As a lowest level operation, the main program can load individual plug-ins from known locations using <a class="el" href="group__cFuncsPlugin.html#gcb92588ad3b48dab5e9487698f6ef437">cp_load_plugin_descriptor</a> and <a class="el" href="group__cFuncsPlugin.html#gc862fd9be2bad2e0dfaafa6216ad34d4">cp_install_plugin</a>.

Plug-in collections can be registered with a plug-in context using <a class="el" href="group__cFuncsContext.html#g998d8350e64a129101f9da687ff5713b">cp_register_pcollection</a>. Plug-ins of the collection can then be scanned and loaded using <a class="el" href="group__cFuncsPlugin.html#ga9603cd8d153b0ce192ac7b6e56779af">cp_scan_plugins</a>. Here is example code loading plug-ins from a plug-in collection.<p>

+Controlling plug-in execution</a></h3>
+The main program controls plug-in execution by starting and stopping plug-ins and by executing run functions registered by plug-ins. Additionally, the main program can pass startup arguments to plug-ins.<p>
+When plug-ins are installed they are not yet activated and their runtime library is not even loaded at that point. The main program typically activates plug-ins by starting a main plug-in responsible for user interface or core application logic. This plug-in then implicitly causes other plug-ins to be activated via dependencies and by dynamically resolving symbols provided by other plug-ins. Plug-ins recursively activate each other until all initially needed plug-ins have been started. Some plug-ins might be activated at a later time when their functionality is needed, for example due to user action.<p>
+If a plug-in needs to perform background operations, that is operations executed outside the invocation of plug-in provided interface functions, then it can either start a new thread or it can register a run function. A run function is a function that is typically executed as part of the main loop by the main program.<p>
+The following example code shows how a main program might initialize plug-in startup arguments using <a class="el" href="group__cFuncsPluginExec.html#g9233fa8a46e408044030d2d767f1fda4">cp_set_context_args</a>, start the core plug-in using <a class="el" href="group__cFuncsPlugin.html#g2456b7740351c2530376ffb3a5ab7d92">cp_start_plugin</a> and then execute plug-in run functions using <a class="el" href="group__cFuncsPluginExec.html#g4668727a5b1c9f0531f6d5dc77fa9f9f">cp_run_plugins</a>.<p>

+</pre></div><h3><a class="anchor" name="cMainProgramChange">
+Changing plug-in configuration</a></h3>
+C-Pluff has been designed to allow dynamic changes to the plug-in configuration, that is plug-ins being added or removed without shutting down the application or the framework. It is the responsibility of the main program to manage such changes if the application is to support dynamic configuration changes.<p>
+Adding plug-ins is straightforward because there is no need to consider dependencies of active plug-ins. For example, if one uses plug-in collections as introduced above then new plug-ins can be deployed under the plug-in collection directory while the application is running and the main program can load them incrementally by calling <a class="el" href="group__cFuncsPlugin.html#ga9603cd8d153b0ce192ac7b6e56779af">cp_scan_plugins</a> again. This call might be activated by some user interface element, for example a plug-in manager component which just downloaded and installed new plug-ins as requested by the user. The flags <a class="el" href="group__cScanFlags.html#gb5996fbc57c7ec3bb538bc80a3ebfc40">CP_SP_STOP_ALL_ON_INSTALL</a> and <a class="el" href="group__cScanFlags.html#g7ca04507561932ae293e81c3636768b7">CP_SP_RESTART_ACTIVE</a> orred together can be used to cause all active plug-ins to be restarted if they do not otherwise notice the extensions provided by new plug-ins.<p>
+Upgrading plug-ins is almost as straightforward because the C-Pluff framework manages plug-in dependencies (assuming the plug-ins have declared their dependencies properly). The new version of a plug-in can be deployed under the plug-in collection directory in a new subdirectory parallel to the old version while the application is running. The main program can then call <a class="el" href="group__cFuncsPlugin.html#ga9603cd8d153b0ce192ac7b6e56779af">cp_scan_plugins</a> with <a class="el" href="group__cScanFlags.html#g1d4b72334d60f1401e6616da54e4d6f1">CP_SP_UPGRADE</a> and <a class="el" href="group__cScanFlags.html#g7ca04507561932ae293e81c3636768b7">CP_SP_RESTART_ACTIVE</a> orred together. This will stop the old version of the upgraded plug-in (implicitly stopping all plug-ins that depend on it), unload the plug-in from the framework, install the new version of the plug-in and finally restart plug-ins that were active before the operation. The old version of the plug-in can now be removed from the plug-in collection. Again, <a class="el" href="group__cScanFlags.html#g72cdcd1181d60fd3caf5d0e0dd59c33c">CP_SP_STOP_ALL_ON_UPGRADE</a> can be added to restart all active plug-ins.<p>
+Deleting plug-ins must be done by first stopping and unloading the plug-in to be deleted using <a class="el" href="group__cFuncsPlugin.html#g2249552dc67bb7893f81babee4a27454">cp_uninstall_plugin</a>. The the plug-in can be removed from the plug-in collection.<h3><a class="anchor" name="cMainProgramDestroyFramework">
+Destroying the plug-in framework</a></h3>
+The plug-in framework can be destroyed and all resources released by calling <a class="el" href="group__cFuncsInit.html#g8dfbe51a3b7f23368a4ddf0d9987180e">cp_destroy</a> as many times as <a class="el" href="group__cFuncsInit.html#gc72ffd50777c3e898dae661c67b04ba9">cp_init</a> has been called. This is not a thread-safe operation and should generally be done by the main program just before application exits. The destroy function stops and unloads all plug-ins and destroys all plug-in contexts before destroying the core framework.<p>
+Individual plug-in contexts can be destroyed by calling <a class="el" href="group__cFuncsContext.html#g754ff895992fab0aae81a09c727e5868">cp_destroy_context</a>. The destroy function stops and unloads all plug-ins before destroying the context itself. <hr size="1">

+<h1>Graph Legend</h1>This page explains how to interpret the graphs that are generated by doxygen.<p>
+Consider the following example: <div class="fragment"><pre class="fragment"><span class="comment">/*! Invisible class because of truncation */</span>
+<span class="keyword">class </span>Invisible { };
+<span class="comment"></span>
+<span class="comment">/*! Truncated class, inheritance relation is hidden */</span>

+<span class="keyword">class </span>Undocumented { };
+<span class="comment"></span>
+<span class="comment">/*! Class that is inherited using public inheritance */</span>
+<span class="keyword">class </span>PublicBase : <span class="keyword">public</span> Truncated { };
+<span class="comment"></span>
+<span class="comment">/*! A template class */</span>
+<span class="keyword">template</span><<span class="keyword">class</span> T> <span class="keyword">class </span>Templ { };

+};
+</pre></div> If the <code>MAX_DOT_GRAPH_HEIGHT</code> tag in the configuration file is set to 240 this will result in the following graph:<p>
+<center><div align="center">
+<img src="graph_legend.png" alt="graph_legend.png">
+</div>
+</center> <p>
+The boxes in the above graph have the following meaning: <ul>
+<li>
+A filled black box represents the struct or class for which the graph is generated. </li>
+<li>
+A box with a black border denotes a documented struct or class. </li>
+<li>
+A box with a grey border denotes an undocumented struct or class. </li>
+<li>
+A box with a red border denotes a documented struct or class forwhich not all inheritance/containment relations are shown. A graph is truncated if it does not fit within the specified boundaries. </li>
+</ul>
+The arrows have the following meaning: <ul>
+<li>
+A dark blue arrow is used to visualize a public inheritance relation between two classes. </li>
+<li>
+A dark green arrow is used for protected inheritance. </li>
+<li>
+A dark red arrow is used for private inheritance. </li>
+<li>
+A purple dashed arrow is used if a class is contained or used by another class. The arrow is labeled with the variable(s) through which the pointed class or struct is accessible. </li>
+<li>
+A yellow dashed arrow denotes a relation between a template instance and the template class it was instantiated from. The arrow is labeled with the template parameters of the instance. </li>

+</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
+These functions are used to manage plug-in contexts from the main program perspective.
+<p>
+They are not intended to be used by a plug-in runtime. From the main program perspective a plug-in context is a container for installed plug-ins. There can be several plug-in context instances if there are several independent sets of plug-ins. However, different plug-in contexts are not very isolated from each other in practice because the global symbols exported by a plug-in runtime in one context are visible to all plug-ins in all context instances.

A run function should do a finite chunk of work and then return telling whether there is more work to be done. A run function is automatically unregistered when the plug-in is stopped. Run functions make it possible for plug-ins to control the flow of execution or they can be used as a coarse way of task switching if there is no multi-threading support.<p>
+The C-Pluff distribution includes a generic main program, cpluff-loader, which only acts as a plug-in loader. It loads and starts up the specified plug-ins, passing any additional startup arguments to them and then just calls run functions of the plug-ins. This makes it is possible to put all the application specific logic in plug-ins. Application does not necessarily need a main program of its own.<p>
+It is also safe, from framework perspective, to call these functions from multiple threads. Run functions may then be executed in parallel threads.

+The target element or attribute is specified by a base element and a relative path from the base element to the target element or attributes. The path includes element names separated by slash '/'. Two dots ".." can be used to designate a parent element. The path may end with '@' followed by an attribute name to select an attribute. Returns NULL if the specified element or attribute does not exist or does not have a value. If there are several subelements with the same name, this function chooses the first one when traversing the tree.<p>

+Resolves a symbol provided by the specified plug-in.
+<p>
+The plug-in is started automatically if it is not already active. The symbol may be context specific or global. The framework first looks for a context specific symbol and then falls back to resolving a global symbol exported by the plug-in runtime library. The symbol can be released using <a class="el" href="group__cFuncsSymbols.html#g150629125a61ac9fa4e2095b0d9c7e57">cp_release_symbol</a> when it is not needed anymore. Pointers obtained from this function must not be passed on to other plug-ins or the main program.<p>
+When a plug-in runtime calls this function the plug-in framework creates a dynamic dependency from the symbol using plug-in to the symbol defining plug-in. The symbol using plug-in is stopped automatically if the symbol defining plug-in is about to be stopped. If the symbol using plug-in does not explicitly release the symbol then it is automatically released after a call to the stop function. It is not safe to refer to a dynamically resolved symbol in the stop function except to release it using <a class="el" href="group__cFuncsSymbols.html#g150629125a61ac9fa4e2095b0d9c7e57">cp_release_symbol</a>.<p>
+When the main program calls this function it is the responsibility of the main program to always release the symbol before the symbol defining plug-in is stopped. It is a fatal error if the symbol is not released before the symbol defining plug-in is stopped.<p>

+A plug-in context represents the co-operation environment of a set of plug-ins from the perspective of a particular participating plug-in or the perspective of the main program.
+<p>
+It is used as an opaque handle to the shared resources but the framework also uses the context to identify the plug-in or the main program invoking framework functions. Therefore a plug-in should not generally expose its context instance to other plug-ins or the main program and neither should the main program expose its context instance to plug-ins. The main program creates plug-in contexts using <a class="el" href="group__cFuncsContext.html#g7d239c4fc07cf7d3095a20900444ad62">cp_create_context</a> and plug-ins receive their plug-in contexts via <a class="el" href="structcp__plugin__runtime__t.html#f193bb8481e4b6aeab275fa5908a9af9">cp_plugin_runtime_t::create</a>.

+</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
+Macros for controlling inter-module symbol visibility and linkage.
+<p>
+These macros have platform specific values. <a class="el" href="group__symbolVisibility.html#ga2e3768d73167e12c2330e4b96bcbd70">CP_EXPORT</a>, <a class="el" href="group__symbolVisibility.html#gb44eb8224723b45a1c909177bdd7bc32">CP_IMPORT</a> and <a class="el" href="group__symbolVisibility.html#gf58571664980e1a0d2b0bee413296492">CP_HIDDEN</a> can be reused by plug-in implementations for better portability. The complexity is mostly due to Windows DLL exports and imports.<p>
+<a class="anchor" name="symbolVisibilityExample"></a> Each module should usually define its own macro to declare API symbols with <a class="el" href="group__symbolVisibility.html#ga2e3768d73167e12c2330e4b96bcbd70">CP_EXPORT</a> and <a class="el" href="group__symbolVisibility.html#gb44eb8224723b45a1c909177bdd7bc32">CP_IMPORT</a> as necessary. For example, a mobule could define a macro <code>MY_API</code> in the API header file as follows.<p>
+<div class="fragment"><pre class="fragment"><span class="preprocessor"> #ifndef MY_API</span>
+<span class="preprocessor"></span><span class="preprocessor"> # define MY_API CP_IMPORT</span>
+<span class="preprocessor"> #endif</span>
+</pre></div><p>
+By default the API symbols would then be marked for import which is correct when client modules are including the API header file. When compiling the module itself the option <code>-DMY_API=CP_EXPORT</code> would be passed to the compiler to override the API header file and to mark the API symbols for export. The overriding definition could also be included in module source files or in an internal header file before including the API header file.

+Declares a symbol hidden from other modules.
+<p>
+This macro should be placed at the start of the symbol declaration to hide the symbol from other modules (if supported by the platform). This macro is not intended to be used with symbols declared as "static" which are already internal to the object file. Some platforms do not support hiding of symbols and therefore unique prefixes should be used for global symbols internal to the module even when they are declared using this macro.

+<h1>C-Pluff C API Documentation</h1>
+<p>
+<h3 align="center">0.1.3 </h3>This is reference documentation for the <a href="http://www.c-pluff.org/">C-Pluff</a> C API. C-Pluff is a plug-in framework for C programs. It has been strongly inspired by the Java plug-in framework in <a href="http://www.eclipse.org/">Eclipse</a>. C-Pluff focuses on providing core services for plug-in interaction and plug-in management. It aims to be platform neutral and supports dynamic changes to plug-in configuration without stopping the whole application or framework. It does not yet provide special facilities for distribution such as signed plug-in packages or remote plug-in repositories but it is possible to build such features on top of the current framework.<p>

+Overview</a></h2>
+Plug-in is the core element of an extensible application. The extensions and also the main application logic are implemented as plug-ins. Plug-ins can be developed, distributed and deployed independently, subject to inter-plugin dependencies. Deploying a new plug-in does not require recompilation or relinking if the operating system platform supports required dynamic linking facilities.<h2><a class="anchor" name="pluginStructure">
+Structure</a></h2>
+A plug-in includes the following structural elements.<p>
+<ul>
+<li><a class="el" href="plugin.html#pluginDescriptor">Plug-in descriptor</a></li><li><a class="el" href="plugin.html#pluginRuntime">Plug-in runtime library</a></li><li><a class="el" href="plugin.html#pluginData">Static plug-in data</a></li></ul>
+<h3><a class="anchor" name="pluginDescriptor">
+Plug-in descriptor</a></h3>
+A plug-in descriptor is an XML document describing a plug-in. It includes information about the contents of the plug-in, the features provided by the plug-in, plug-in version information and static dependencies of the plug-in. Most of the elements are optional. Most of the descriptor information described here is available to software via <a class="el" href="structcp__plugin__info__t.html">cp_plugin_info_t</a> structure. The plug-in descriptor must be located in the plug-in directory as <code>plugin.xml</code>.<p>
+The formal declaration of plug-in descriptor is available as XML Schema Definition in <code>plugin.xsd</code> located in the top level source directory. Currently there is no namespace associated with the plug-in descriptor. Here is an example of a plug-in descriptor. Click element name to jump into documentation for that element.<p>

+A descriptor can also be much simpler, depending on the plug-in. Here is an example of a minimal descriptor (of a useless plug-in).<p>
+<div class="fragment"> <pre class="fragment">
+ <<a href="#pluginDescPlugin" class="code">plugin</a> id=<span class="charliteral">"org.c-pluff.useless"</span>/></pre> </div><h4><a class="anchor" name="pluginDescPlugin">
+plugin</a></h4>
+This is the top level element of the plug-in descriptor. It can have following attributes.<p>
+<ul>
+<li><em>id:</em> A mandatory unique identifier for the plug-in. Plug-in identifiers should preferably be generated using a reversed DNS domain name as prefix to prevent identifier conflicts.</li><li><em>name:</em> An optional human-readable name for the plug-in.</li><li><em>version:</em> An optional version number for the plug-in. Version numbers are used for checking compatibility when resolving versioned plug-in dependencies. See also information about plug-in versions.</li><li><em>provider-name</em>: The name of the plug-in provider or author. Optional.</li></ul>
+<p>
+This element can contain following elements.<p>
+<ul>
+<li><a class="el" href="plugin.html#pluginDescPluginBWC">backwards-compatibility</a>: Optional information about backwards compatibility of this plug-in version.</li><li><a class="el" href="plugin.html#pluginDescPluginRequires">requires</a>: Information about static plug-in dependencies. Can be omitted if the plug-in does not have static dependencies.</li><li><a class="el" href="plugin.html#pluginDescPluginRuntime">runtime</a>: Information about the plug-in runtime library. Can be omitted if the plug-in does not have a runtime library but only data.</li><li><a class="el" href="plugin.html#pluginDescPluginEP">extension-point</a>: Information about extension points provided by the plug-in. This element is repeated if there are multiple extension points and omitted if there are none.</li><li><a class="el" href="plugin.html#pluginDescPluginE">extension</a>: Information about extensions provided by the plug-in. This element is repeated if there are multiple extensions and omitted if there are none.</li></ul>
+<h4><a class="anchor" name="pluginDescPluginBWC">
+backwards-compatibility</a></h4>
+This element includes optional information about the backwards compatibility of this plug-in version. It can have following attributes.<p>
+<ul>
+<li><em>abi:</em> Backwards compatibility of the application binary interface (ABI) of the plug-in. ABI includes any public symbols exported by the plug-in, data structures associated with exported symbols and any extension points provided by the plug-in. The ABI of the current plug-in version is backwards compatible with any plug-in version from the version specified here to the current version. This information is used when resolving versioned plug-in dependencies. See also information about plug-in versions.</li><li><em>api:</em> Backwards compatibility of the application programming interface (API) of the plug-in. API compatibility means that source code developed against one version of the plug-in also compiles against another version of the plug-in. This information is not used by framework but it can be used by a developer developing dependent plug-ins.</li></ul>
+<p>
+These apply to plug-ins that provide header files and runtime libraries. For example, a plug-in might export global functions to other plug-ins or it might provide an extension point where an extension installed by other plug-in must conform to data structures defined by the plug-in. Both attributes are optional.<h4><a class="anchor" name="pluginDescPluginRequires">
+requires</a></h4>
+This element includes information about static plug-in dependencies. It can be omitted if there are no dependencies. It can contain following elements.<p>
+<ul>
+<li><a class="el" href="plugin.html#pluginDescPluginReqCP">c-pluff</a>: An optional version dependency on the C-Pluff implementation.</li><li><a class="el" href="plugin.html#pluginDescPluginReqImport">import</a>: Declares a static dependency on other plug-in. This element is repeated if there are multiple dependencies and omitted if there are none.</li></ul>
+<h4><a class="anchor" name="pluginDescPluginReqCP">
+c-pluff</a></h4>
+This element declares a version dependency on the C-Pluff implementation. It can be used to ensure that the plug-in is not loaded by incompatible C-Pluff version. It has the following attribute.<p>
+<ul>
+<li><em>version:</em> The required version of the C-Pluff implementation. This is used when resolving the plug-in. It is checked that the used C-Pluff implementation is backwards compatible with the version specified here when it comes to the application binary interface (ABI) of C-Pluff.</li></ul>
+<h4><a class="anchor" name="pluginDescPluginReqImport">
+import</a></h4>
+This element declares a static dependency on other plug-in. It must be used when a plug-in uses global symbols or data from other plug-in or when a plug-in uses an extension point defined by other plug-in or whenever some other plug-in needs to be there for the plug-in to work. The framework takes care of resolving and starting the dependencies whenever the plug-in is resolved or started.<p>
+This element can have following attributes.<p>
+<ul>
+<li><em>plugin:</em> The identifier of the imported plug-in.</li><li><em>version:</em> An optional version dependency on the imported plug-in. The plug-in can be resolved only if the version of the imported plug-in is backwards compatible with the version specified here when it comes to the application binary interface (ABI) of the imported plug-in.</li><li><em>optional:</em> Is the import optional or not ("true" or "false"). Default is false, a mandatory import. An optional import behaves just like the mandatory import as long as the imported plug-in is present. However, if it is not present then the import is ignored. Optional import can be used if the plug-in works in limited capacity even without the specified plug-in.</li></ul>
+<h4><a class="anchor" name="pluginDescPluginRuntime">
+runtime</a></h4>
+This element contains information about the plug-in runtime library. It is omitted if the plug-in does not have a runtime library but contains only data. It can have following attributes.<p>
+<ul>
+<li><em>library:</em> The name of the plug-in runtime library in the plug-in directory. A platform specific extension (for example, ".so" or ".dll") is added to the value specified here when loading the library.</li><li><em>funcs:</em> The functions to be used to create an instance of the plug-in runtime. This attribute is optional. It is needed if the plug-in has a start or stop function. The value specified here is a name of an exported symbol which contains a pointer to <a class="el" href="structcp__plugin__runtime__t.html">cp_plugin_runtime_t</a> structure.</li></ul>
+<h4><a class="anchor" name="pluginDescPluginEP">
+extension-point</a></h4>
+This element defines an extension point provided by the plug-in. It can have following attributes.<p>
+<ul>
+<li><em>id:</em> The local identifier of the extension point. The value specified here is prefixed with the identifier of the plug-in and dot to construct the global identifier of the extension point.</li><li><em>name:</em> An optional human-readable name describing the use of the extension point.</li><li><em>schema:</em> An optional path to the extension point XML schema in the plug-in directory. This information is not currently used by the framework. But it can be used by a developer to determine what information should be provided by extensions attached to this extension point.</li></ul>
+<h4><a class="anchor" name="pluginDescPluginE">
+extension</a></h4>
+This element defines an extension installed into a specified extension point provided by the defining plug-in or some other plug-in. It can have following attributes.<p>
+<ul>
+<li><em>point:</em> The global identifier of the associated extension point.</li><li><em>id:</em> An optional local identifier for the extension. The value specified here is prefixed with the identifier of the plug-in and dot to construct the global identifier for the extension.</li><li><em>name:</em> An optional human-readable name describing the extension.</li></ul>
+<p>
+The extension element can contain XML elements specific to the associated extension point (conforming to the schema defined by the extension point).<h3><a class="anchor" name="pluginRuntime">
+Plug-in runtime library</a></h3>
+A plug-in runtime library is an optional plug-in element. Plug-ins only supplying static data in form of XML data and files do not need a runtime library. However, a typical plug-in does provide program logic as well.<p>
+The plug-in runtime library includes all program logic and program data provided by the plug-in. It is simply a shared library, or a dynamically linked library, which is linked in to the application when the plug-in is started. When plug-in is unloaded, the runtime library is unloaded as well. The framework has been designed to manage dependencies so that unloading of the runtime library does not cause problems, provided that plug-ins behave properly.<p>
+A plug-in can expose functionality to other plug-ins either as exported global symbols that are directly resolved by other plug-ins or by supplying extensions. When other plug-ins are directly using exported symbols the plug-in acts just like any standard shared library. Nothing special there. The more interesting case is exposing functionality as extensions. Because the extension is registered at a specific extension point, the logic in other plug-ins can use the extension and the associated program logic even if they are not aware of the existence of the extension supplying plug-in.<p>
+The extension points accepting program logic as extensions define a way to specify the name of the symbol pointing to the supplied logic. This is typically an attribute of an XML element contained in the extension definition. The plug-in supplying the extension can then export the program logic as a global symbol with arbitrary name and then place the name of the symbol in extension data. Alternatively, the plug-in can define a virtual symbol at runtime using <a class="el" href="group__cFuncsSymbols.html#g9d128b52c0ffe2d4215026fe59f9abeb">cp_define_symbol</a>. Other plug-ins that are using extensions registered at the extension point can then resolve the named symbol using <a class="el" href="group__cFuncsSymbols.html#g8bc3b7fcf4f4ed414837f5a3998d46b7">cp_resolve_symbol</a> at runtime. The framework automatically creates a dependency from the symbol using plug-in to the symbol supplying plug-in to prevent failures in case the symbol supplying plug-in is stopped or unloaded.<h3><a class="anchor" name="pluginData">
+Static plug-in data</a></h3>
+Plug-in can supply static data to other plug-ins using at least two different mechanisms. A plug-in can easily provide static XML data as part of extension elements. Additionally, a plug-in directory can contain files that may be accessed by other plug-ins. Currently the platform does not provide assistance in accessing data files provided by other plug-ins. However, a plug-in can locate the plug-in directory and thus any included data files by using plug-in path available in <a class="el" href="structcp__plugin__info__t.html">cp_plugin_info_t</a> structure of the data providing plug-in. <hr size="1">

+Container for plug-in runtime information.
+<p>
+A plug-in runtime defines a static instance of this structure to pass information to the plug-in framework. The plug-in framework then uses the information to create and control plug-in instances. The symbol pointing to the runtime information instance is named by the <em>funcs</em> attribute of the <em>runtime</em> element in a plug-in descriptor.<p>
+The following graph displays how these functions are used to control the state of the plug-in instance.<p>

+INSTALLING C-PLUFF EXAMPLES
+===========================
+
+This directory includes examples of extensible applications based on
+C-Pluff. You can build the examples as part of the C-Pluff source tree at
+the same time as building the C-Pluff implementation or as a stand-alone
+build using an already installed C-Pluff instance.
+
+These are generic build and installation instructions. For more
+information on an individual example, see README.txt in the corresponding
+subdirectory.
+
+
+Building as part of the C-Pluff source tree
+-------------------------------------------
+
+This build method can be used if you are building the C-Pluff
+implementation and the examples at the same time using the supplied GNU
+autotools based build environment. If this is not the case, skip to the
+next section.
+
+Configure C-Pluff as usual using the configure script in the top level
+source directory. To build and install the examples make targets
+"examples" and "examples-install", respectively, in the top level source
+directory. This will build and install the C-Pluff implementation together
+with the example applications.
+
+Notice that example applications will be installed into the same prefix
+as the C-Pluff implementation.
+
+
+Building in stand-alone mode using GNU autotools
+------------------------------------------------
+
+This build method more correctly reflects the way real independent
+applications would be built. It is assumed that you already have an
+installed C-Pluff instance and you wish to configure, build and install
+the example applications separately using GNU autotools. If you wish to
+use Windows specific tools, skip to next section.
+
+If you don't have write access to the example source directory (because
+it is part of the installed C-Pluff documentation), make a personal copy
+of the source directory.
+
+ cp -r INSTALLED_SOURCE MY_SOURCE
+
+To use this build method, you must have some GNU tools installed because
+the C-Pluff source distribution does not ship intermediate build system
+files for examples. You will need these tools anyway if you are about to
+develop applications using a build system similar to these examples. The
+version numbers in parentheses are known working versions.
+
+ - GNU Autoconf (2.61)
+ - GNU Automake (1.10)
+ - GNU libtool (1.5.22)
+
+To bootstrap the build system, run the autogen.sh script in the source
+directory. It will invoke the above mentioned GNU tools to generate
+intermediate build system files.
+
+ ./autogen.sh
+
+Alternatively, if you want to get more familiar with the process, you can
+browse through the script and execute the necessary commands manually.
+
+Now you should have a build system in place and you can configure and
+build the examples using the standard autotools procedure.
+
+ Building in the source directory:
+ ./configure
+ make
+
+ Building in a separate build directory:
+ cd BUILD_DIR
+ SOURCE_DIR/configure
+ make
+
+When configuring, you can use the --prefix option to choose another
+installation prefix for the examples (the default is /usr/local).
+
+If C-Pluff has been installed into a location that is not included in the
+standard include or library path then you have to specify some additional
+environment variables to the configure script. Assuming that C-Pluff was
+installed into /usr/local (the default), you would have to set following
+environment variables before calling configure.
+
+ CPPFLAGS="-I/usr/local/include"
+ LDFLAGS="-L/usr/local/lib"
+ CPLUFF_LOADER="/usr/local/bin/cpluff-loader"
+
+Finally, install the example applications.
+
+ make install
+
+
+Building in stand-alone mode using Microsoft Visual C
+-----------------------------------------------------
+
+This build method is specific to Microsoft Visual C. It is provided
+separately because of complexity involved in setting up more generic GNU
+tools on Windows platform. Be warned that this build method is not being
+tested as often as the GNU autotools based build method. Please report
+any problems to the C-Pluff users mailing list.
+
+The included build environment and these instructions were initially
+tested with Microsoft Visual C++ 2005 Express Edition. The build
+environment relies only on command line tools. It is assumed that the
+given commands will be entered into command prompt.
+
+As the first step, you have to set up correct paths in common.nmake using
+Notepad or some other text editor. If you are building example source that
+has been extracted from cpluff-VER.zip (or cpluff-VER-only.zip) Windows
+distribution then the default settings should be fine. Examples will be
+installed to the same path as the C-Pluff implementation by default.
+
+Before trying to use the Visual C command line tools, you have to set up
+required environment variables by executing vcvarsall.bat in the Visual C
+installation directory. Alter the path in the following example as
+necessary for your installation.
+
+ C:\"Program Files"\"Microsoft Visual Studio 8"\VC\vcvarsall
+
+The C-Pluff Windows distribution includes a precompiled C-Pluff runtime
+library as DLL. Additionally, on Windows platform you will also need a
+corresponding import library to be able to compile software that uses a
+DLL. For some reason import libraries generated by different Windows
+compilers (MinGW, Visual C, Borland C, etc.) are generally incompatible.
+The C-Pluff Windows distribution only includes an import library for MinGW
+(libcpluff.dll.a) so you have to generate one for Visual C.
+
+This can be done using the Microsoft Library Manager, or lib.exe, and the
+export definitions provided in libcpluff.def. Execute the following
+command in the library directory containing libcpluff.def.
+
+ lib /machine:I386 /name:libcpluff-0.dll /def:libcpluff.def /out:libcpluff.lib
+
+This should generate libcpluff.lib, an import library for Visual C.
+
+Now you should be ready to build the examples. Build the examples by
+making target "all" in Makefile.nmake in the examples directory using
+nmake.
+
+ nmake /f Makefile.nmake all
+
+This compiles the examples but does not yet install them. To install
+required files to the installation directory make target "install" in
+Makefile.nmake in the examples directory using nmake.
+
+ nmake /f Makefile.nmake install

+C-PLUFF FILE COMMAND EXAMPLE
+============================
+
+Overview
+--------
+
+On UNIX systems the file(1) utility can be used to determine file type and
+to get information about contents of a file. Here are couple of examples
+of file usage in a Linux environment.
+
+ $ file /sbin/init
+ /sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
+ for GNU/Linux 2.4.1, dynamically linked (uses shared libs), for
+ GNU/Linux 2.4.1, stripped
+
+ $ file COPYRIGHT.txt
+ COPYRIGHT.txt: ASCII English text
+
+This example shows how a simplistic file clone could be implemented as an
+extensible application based on C-Pluff. We will call the resulting
+utility cpfile. It can recognize some special files and some file types
+based on file extension. But it could be further extended to recognize
+files based on their content by deploying a suitable plug-in. Notice that
+the focus here was on creating a straightforward example rather than an
+efficient one.
+
+
+Architecture
+------------
+
+This example uses the generic plug-in loader, cpluff-loader, as the main
+program. The executable cpfile installed into the bin directory is just
+a shell script invoking the cpluff-loader. All program logic is included
+in plug-ins.
+
+The included plug-ins are:
+
+ org.c-pluff.examples.cpfile.core
+
+ This plug-in is the one initially started via cpluff-loader. It
+ contains the core application logic and provides an extension point
+ for file classifiers. The plug-in itself does not include any file
+ classifiers. Instead it uses file classifiers registered as
+ extensions by other plug-ins and then tries them one at a time in
+ order of decreasing priority until a matching classification is
+ found or no more classifiers are left.
+
+ org.c-pluff.examples.cpfile.special
+
+ This plug-in provides a file classifier which uses lstat(2) on the
+ file to be classified to see if it is a special file such as a
+ directory or a symbolic link. It also checks for the existence of
+ the file.
+
+ org.c-pluff.examples.cpfile.extension
+
+ This plug-in provides a file classifier which checks the file name
+ for known extensions. The plug-in provides an extension point for
+ file extensions. The file extensions registered as extensions are
+ then matched against the file name. The plug-in itself includes an
+ extension for text files.
+
+ org.c-pluff.examples.cpfile.cext
+
+ This plug-in does not include a runtime library at all. Instead, it
+ just registers some file types and file extensions related to
+ C program source files.
+
+Having build and installed the example, you can experiment with different
+plug-in configurations by adding and removing plug-ins into cpfile/plugins
+directory in the library directory. The core plug-in must be always
+included for the application to work as intended.
+
+You can create a new plug-in for the example by creating a new
+subdirectory in the plugins source directory and adding it to SUBDIRS
+variable in Makefile.am in the plugins source directory.
+
+
+Example runs
+------------
+
+Here are couple of examples of using the resulting cpfile application.
+
+ $ cpfile /tmp/testdir
+ C-Pluff Loader, version 0.1.0
+ C-Pluff Library, version 0.1.0 for i686-pc-linux-gnu
+ /tmp/testdir: directory
+
+ $ cpfile /tmp/test.foo
+ C-Pluff Loader, version 0.1.0
+ C-Pluff Library, version 0.1.0 for i686-pc-linux-gnu
+ /tmp/test.foo: unknown file type
+
+ $ cpfile /tmp/test.c
+ C-Pluff Loader, version 0.1.0
+ C-Pluff Library, version 0.1.0 for i686-pc-linux-gnu
+ /tmp/test.c: C source file
+
+ $ cpfile /tmp/test.nonexisting
+ C-Pluff Loader, version 0.1.0
+ C-Pluff Library, version 0.1.0 for i686-pc-linux-gnu
+ /tmp/test.nonexisting: stat failed: No such file or directory
+
+You can make cpfile more quiet by giving it -q option, or more verbose by
+giving it -v option (repeated for more verbosity up to -vvv). Actually,
+these options are processed by cpluff-loader which configures logging
+accordingly.
+
+ $ cpfile -q /tmp/test.c
+ /tmp/test.c: C source file
+
+ $ cpfile -vv /tmp/test.c
+ C-Pluff Loader, version 0.1.0

+ * and the hash_isfull() function returns true.
+ * 5. The high mark is a population threshold, measured as a number of nodes,
+ * which, if exceeded, will trigger a table expansion. Only dynamic hash
+ * tables are subject to this expansion.

+ * will shrink beneath a certain absolute minimum number of nodes.

+ * 8. Pointer to the table's hashing function, set once at creation or
+ * initialization time.
+ * 9. The current hash table mask. If the size of the hash table is 2^N,

+/**
+ * @page architecture Plug-in architecture
+ *
+ * @section architectureOverview Overview
+ *
+ * The plug-in architecture supported by C-Pluff is presented in the
+ * following figure. There is a thin main program controlling the plug-in
+ * framework. The main program is responsible for initializing and setting
+ * up the plug-in environment. Most of the application logic is contained in
+ * plug-ins which are independent components and can be developed and
+ * distributed separately. Plug-ins integrate with each other by providing
+ * extension points and extensions. An extension point is a point into which
+ * other plug-ins can attach extensions. An extension can be just
+ * information, expressed in XML format, or the plug-in may also provide
+ * program logic as part of the plug-in runtime library. The framework
+ * provides services for accessing extensions and for managing plug-in
+ * dependencies.
+ *
+ * @image html architecture.png "C-Pluff plug-in architecture"
+ *
+ * @section architectureExtensions Extensions
+ *
+ * The idea behind extension points and extensions is that the extensibility
+ * is not limited only to few fixed plug-in types supported by the
+ * core application. Although the core plug-ins typically define the extension
+ * points for the core application logic, it is possible for any plug-in
+ * to specify additional extension points.
+ *
+ * For example, let us assume that we are developing an extensible text
+ * editor. One extension point defined by core editor plug-in could be
+ * auto-completion extension point. A plug-in providing basic Java source code
+ * support could provide an extension for auto-completing Java code.
+ * Now, while this extension could do basic auto-completion of plain Java code,
+ * it is customary that Java source code also includes embedded documentation,
+ * such as JavaDoc comments and tags, or annotations, such as XDoclet tags, as
+ * part of doc comments. Instead of trying to support all known tags and their
+ * semantics, the plug-in providing basic Java support could define another
+ * extension point for additional plug-ins that know how to perform
+ * auto-completion of different kind of tags in doc comments.
+ * This way the extensibility of the application is not limited to the
+ * extension points defined by the core application but the plug-ins can
+ * incrementally increase the extensibility of the application.

+/**
+ * @mainpage
+ *
+ * This is reference documentation for the
+ * <a href="http://www.c-pluff.org/">C-Pluff</a> C API.
+ * C-Pluff is a plug-in framework for C programs.
+ * It has been strongly inspired by the Java plug-in framework in
+ * <a href="http://www.eclipse.org/">Eclipse</a>. C-Pluff focuses on
+ * providing core services for plug-in interaction and plug-in
+ * management. It aims to be platform neutral and supports dynamic changes to
+ * plug-in configuration without stopping the whole application or framework.
+ * It does not yet provide special facilities for distribution such as
+ * signed plug-in packages or remote plug-in repositories but it is
+ * possible to build such features on top of the current framework.
+ *
+ * Here are links to main topics.
+ *
+ * - @ref architecture "Plug-in architecture"
+ * - @ref cMainProgram "Main program"
+ * - @ref plugin "Plug-in"
+ *
+ * - <a class="el" href="modules.html">API elements</a>
+ * - <a class="el" href="files.html">Header files</a>
+ *
+ * For a "quick start guide" in developing C-Pluff based applications,
+ * see the example in the examples directory of the source distribution.
+ *
+ * The latest version of the framework implementation
+ * and documentation is available at
+ * <a href="http://www.c-pluff.org/">C-Pluff web site</a>.
+ *
+ * This documentation has been generated from the C-Pluff source code

+/**
+ * @page cMainProgram Main program
+ *
+ * @section cMainProgramOverview Overview
+ *
+ * The main program is the part of executable that is located outside the
+ * plug-in framework. The main program is responsible for setting up
+ * the plug-in framework and for loading the desired set of
+ * @ref plugin "plug-ins". The main program should preferably be very
+ * thin, a mere plug-in loader, because it can not fully participate in plug-in
+ * interaction. C-Pluff distribution provides a plug-in loader,
+ * @ref cpluff-loader, which can be used as a generic main program for
+ * arbitrary plug-in collections.
+ *
+ * @section cMainProgramResponsibilities Responsibilities
+ *
+ * The main program has several responsibilities:
+ *
+ * - @ref cMainProgramInitFramework "initializing the plug-in framework"
+ * - @ref cMainProgramCreateContext "creating a plug-in context"
+ * - @ref cMainProgramLoad "loading plug-ins"
+ * - @ref cMainProgramExec "controlling plug-in execution"
+ * - @ref cMainProgramChange "changing plug-in configuration" (opt.)
+ * - @ref cMainProgramDestroyFramework "destroying the plug-in framework"
+ *
+ * @subsection cMainProgramInitFramework Initializing the plug-in framework
+ *
+ * Plug-in framework, or the C-Pluff library, must be initialized before its
+ * services can be used.
+ * Initialization is not a thread-safe operation and should generally be
+ * done by the main program before any additional plug-in framework accessing
+ * threads are started. Initialization is done by calling ::cp_init.
+ * Additionally, the main program can use ::cp_set_fatal_error_handler to register
+ * a function that is called when a fatal error occurs. A fatal error is one
+ * that prevents the framework from continuing operation. For example,
+ * errors in operating system locking operations and a NULL pointer being
+ * passed as an argument which is expected to have a non-NULL value are fatal
+ * erors.
+ *
+ * Here is an example of possible initialization code.
+ *
+ * @code
+ * #include <locale.h>
+ * #include <cpluff.h>
+ *
+ * void handle_fatal_error(const char *msg) {
+ *
+ * // ... log error, flush logs, send bug report, etc. ...
+ *
+ * fprintf(stderr, "A fatal error occurred: %s\n", msg);
+ * abort();
+ * }
+ *
+ * void initialize(void) {
+ * cp_status_t status;
+ *
+ * setlocale(LC_ALL, "");
+ * cp_set_fatal_error_handler(handle_fatal_error);
+ * status = cp_init();
+ * if (status != CP_OK) {
+ * // ... handle initialization failure ...
+ * }
+ * }
+ * @endcode
+ *
+ * @subsection cMainProgramCreateContext Creating a plug-in context
+ *
+ * A plug-in context represents the co-operation environment of a set of
+ * plug-ins from the perspective of a particular participating plug-in or
+ * the perspective of the main program. From main program perspective, a
+ * plug-in context is a container for a set of plug-ins. A plug-in can interact
+ * with other plug-ins in the same container.
+ *
+ * An extensible application can have more than one plug-in container but
+ * usually one container should suffice. Due to the nature of C programs,
+ * plug-ins deployed to different containers are not very well insulated from
+ * each other. For example, global variables provided by a plug-in in one
+ * container are visible to all plug-ins in all containers. Also, by placing
+ * all plug-ins in the same container they can more efficiently share common
+ * base components which themselves might provide extensibility.
+ *
+ * A main program creates a plug-in context, to be used as a container for
+ * plugins, using ::cp_create_context.
+ *
+ * @code
+ * #include <cpluff.h>
+ *
+ * cp_context_t *ctx;
+ *
+ * void create_context(void) {
+ * cp_status_t status;
+ *
+ * ctx = cp_create_context(&status);
+ * if (ctx == NULL) {
+ * // ... handle initialization failure ...
+ * }
+ * }
+ * @endcode
+ *
+ * @subsection cMainProgramLoad Loading plug-ins
+ *
+ * An extensible application is made of plug-ins that can be added and removed
+ * dynamically. The plug-ins are loaded by the main program using the services
+ * provided by the framework. The framework provides couple of alternative
+ * ways of loading plug-ins.
+ *
+ * As a lowest level operation, the main program can
+ * load individual plug-ins from known locations using
+ * ::cp_load_plugin_descriptor and ::cp_install_plugin. Here is example code
+ * that loads a set of plug-ins from file system locations listed in a file.
+ *
+ * @code
+ * #include <stdio.h>
+ * #include <cpluff.h>
+ *
+ * extern cp_context_t *ctx;
+ * static const char pluginListFile[] = "/etc/example/plugins.list";
+ *
+ * void load_plugins(void) {
+ * char plugindir[128];
+ * FILE *lf;
+ *
+ * // Open plug-in list file
+ * lf = fopen(pluginListFile, "r");
+ * if (lf == NULL) {
+ * // ... handle loading failure ...
+ * }
+ *
+ * // Load each listed plug-in
+ * while (fgets(plugindir, 128, lf) != NULL) {
+ * cp_plugin_info_t *plugininfo;
+ * cp_status_t status;
+ * int i;
+ *
+ * // Remove possible trailing newline from plug-in location
+ * for (i = 0; plugindir[i + 1] != '\0'; i++);
+ * if (plugindir[i] == '\n') {
+ * plugindir[i] = '\0';
+ * }
+ *
+ * // Load plug-in descriptor
+ * plugininfo = cp_load_plugin_descriptor(ctx, plugindir, &status);
+ * if (pinfo == NULL) {
+ * // ... handle loading failure ...
+ * }
+ *
+ * // Install plug-in descriptor
+ * status = cp_install_plugin(ctx, plugininfo);
+ * if (status != CP_OK) {
+ * // ... handle loading failure ...
+ * }
+ *
+ * // Release plug-in descriptor information
+ * cp_release_info(ctx, plugininfo);
+ * }
+ *
+ * // Close plug-in list file
+ * fclose(lf);
+ * }
+ * @endcode
+ *
+ * Alternatively, the main program can register and load plug-in collections.
+ * A plug-in collection is a file system directory which includes individual
+ * plug-ins in subdirectories, one plug-in in each subdirectory. Plug-in
+ * collections can be registered with a plug-in context using
+ * ::cp_register_pcollection. Plug-ins of the collection can then be scanned
+ * and loaded using ::cp_scan_plugins. Here is example code loading plug-ins
+ * from a plug-in collection.
+ *
+ * @code
+ * #include <cpluff.h>
+ *
+ * extern cp_context_t *ctx;
+ * static const char pluginCollectionDir[] = "/etc/example/plugins";
+ *
+ * void load_plugins(void) {
+ * cp_status_t status;
+ *
+ * status = cp_register_pcollection(ctx, pluginCollectionDir);
+ * if (status != CP_OK) {
+ * // ... handle loading failure ...
+ * }
+ * status = cp_scan_plugins(ctx, 0);
+ * if (status != CP_OK) {
+ * // ... handle loading failure ...
+ * // (notice that some plug-ins might have been loaded)
+ * }
+ * }
+ * @endcode
+ *
+ * @subsection cMainProgramExec Controlling plug-in execution
+ *
+ * The main program controls plug-in execution by starting and stopping
+ * plug-ins and by executing run functions registered by plug-ins.
+ * Additionally, the main program can pass startup arguments to plug-ins.
+ *
+ * When plug-ins are installed they are not yet activated and their
+ * runtime library is not even loaded at that point. The main program
+ * typically activates plug-ins by starting a main plug-in
+ * responsible for user interface or core application logic. This plug-in
+ * then implicitly causes other plug-ins to be activated via dependencies and
+ * by dynamically resolving symbols provided by other plug-ins. Plug-ins
+ * recursively activate each other until all initially needed plug-ins have
+ * been started. Some plug-ins might be activated at a later time when their
+ * functionality is needed, for example due to user action.
+ *
+ * If a plug-in needs to perform background operations, that is operations
+ * executed outside the invocation of plug-in provided interface functions,
+ * then it can either start a new thread or it can register a run function.
+ * A run function is a function that is typically executed as part of the
+ * main loop by the main program.
+ *
+ * The following example code shows how a main program might initialize
+ * plug-in startup arguments using ::cp_set_context_args, start the core
+ * plug-in using ::cp_start_plugin and then execute plug-in run functions
+ * using ::cp_run_plugins.
+ *
+ * @code
+ * #include <cpluff.h>
+ *
+ * extern cp_context_t *ctx;
+ * static const char corePluginId[] = "org.example.core";
+ *
+ * void run_plugins(char *argv[]) {
+ * cp_status_t status;
+ *
+ * // Set plug-in startup arguments
+ * cp_set_context_args(ctx, argv);
+ *
+ * // Start the core plug-in, possibly activating other plug-ins as well
+ * status = cp_start_plugin(ctx, corePluginId);
+ * if (status != CP_OK) {
+ * // ... handle startup failure ...
+ * }
+ *
+ * // Execute plug-ins until there is no more work to be done
+ * cp_run_plugins(ctx);
+ * }
+ *
+ * int main(int argc, char *argv[]) {
+ * // ... do initialization and load plug-ins ...
+ *
+ * run_plugins(argv);
+ *
+ * // ... do destruction ...
+ * }
+ * @endcode
+ *
+ * Alternatively, if the main program has some operations it must perform
+ * as part of the main loop, the call to ::cp_run_plugins can be replaced
+ * by code using ::cp_run_plugins_step like in the following example.
+ *
+ * @code
+ * void mainloop(void) {
+ * int finished = 0;
+ *
+ * while (!finished) {
+ * // ... do main program specific operations ...
+ *
+ * finished = !cp_run_plugins_step(ctx);
+ * }
+ * }
+ * @endcode
+ *
+ * @subsection cMainProgramChange Changing plug-in configuration
+ *
+ * C-Pluff has been designed to allow dynamic changes to the plug-in
+ * configuration, that is plug-ins being added or removed without shutting
+ * down the application or the framework. It is the responsibility of the
+ * main program to manage such changes if the application is to support
+ * dynamic configuration changes.
+ *
+ * Adding plug-ins is straightforward because there is no need to
+ * consider dependencies of active plug-ins. For example, if one uses
+ * plug-in collections as introduced above then new plug-ins can be
+ * deployed under the plug-in collection directory while the application is
+ * running and the main program can load them incrementally by calling
+ * ::cp_scan_plugins again. This call might be activated by some user interface
+ * element, for example a plug-in manager component which just downloaded and
+ * installed new plug-ins as requested by the user. The flags
+ * #CP_SP_STOP_ALL_ON_INSTALL and #CP_SP_RESTART_ACTIVE
+ * orred together can be used to cause all active plug-ins to be restarted
+ * if they do not otherwise notice the extensions provided by new plug-ins.
+ *
+ * Upgrading plug-ins is almost as straightforward because the C-Pluff
+ * framework manages plug-in dependencies (assuming the plug-ins have
+ * declared their dependencies properly). The new version of a plug-in
+ * can be deployed under the plug-in collection directory in a
+ * new subdirectory parallel to the old version while the application is
+ * running. The main program can then call ::cp_scan_plugins with
+ * #CP_SP_UPGRADE and #CP_SP_RESTART_ACTIVE orred together. This will stop
+ * the old version of the upgraded plug-in (implicitly stopping all plug-ins
+ * that depend on it), unload the plug-in from the framework, install the
+ * new version of the plug-in and finally restart plug-ins that were
+ * active before the operation. The old version of the plug-in can now
+ * be removed from the plug-in collection. Again, #CP_SP_STOP_ALL_ON_UPGRADE
+ * can be added to restart all active plug-ins.
+ *
+ * Deleting plug-ins must be done by first stopping and unloading the
+ * plug-in to be deleted using ::cp_uninstall_plugin. The the plug-in can
+ * be removed from the plug-in collection.
+ *
+ * @subsection cMainProgramDestroyFramework Destroying the plug-in framework
+ *
+ * The plug-in framework can be destroyed and all resources released by
+ * calling ::cp_destroy as many times as ::cp_init has been called. This
+ * is not a thread-safe operation and should generally be done by the main
+ * program just before application exits. The destroy function
+ * stops and unloads all plug-ins and destroys all plug-in contexts before
+ * destroying the core framework.
+ *
+ * Individual plug-in contexts can be destroyed by calling
+ * ::cp_destroy_context. The destroy function stops and unloads all plug-ins
+ * before destroying the context itself.

+/**
+ * @page plugin Plug-in
+ *
+ * @section pluginOverview Overview
+ *
+ * Plug-in is the core element of an extensible application. The extensions and
+ * also the main application logic are implemented as plug-ins. Plug-ins can
+ * be developed, distributed and deployed independently, subject to
+ * inter-plugin dependencies. Deploying a new plug-in does not require
+ * recompilation or relinking if the operating system platform supports
+ * required dynamic linking facilities.
+ *
+ * @section pluginStructure Structure
+ *
+ * A plug-in includes the following structural elements.
+ *
+ * - @ref pluginDescriptor "Plug-in descriptor"
+ * - @ref pluginRuntime "Plug-in runtime library"
+ * - @ref pluginData "Static plug-in data"
+ *
+ * @subsection pluginDescriptor Plug-in descriptor
+ *
+ * A plug-in descriptor is an XML document describing a plug-in. It includes
+ * information about the contents of the plug-in, the features provided by
+ * the plug-in, plug-in version information and static dependencies of the
+ * plug-in. Most of the elements are optional. Most of the descriptor
+ * information described here is available to software via
+ * @ref cp_plugin_info_t structure. The plug-in descriptor must be located
+ * in the plug-in directory as @c plugin.xml.
+ *
+ * The formal declaration of plug-in descriptor is available as
+ * XML Schema Definition in @c plugin.xsd located in the top level source
+ * directory. Currently there is no namespace associated with the plug-in
+ * descriptor. Here is an example of a plug-in descriptor. Click element name
+ * to jump into documentation for that element.

+ * A descriptor can also be much simpler, depending on the plug-in.
+ * Here is an example of a minimal descriptor (of a useless plug-in).
+ *
+ * <div class="fragment">
+ * <pre class="fragment">
+ * <<a class="code" href="#pluginDescPlugin">plugin</a> id=<span class="charliteral">"org.c-pluff.useless"</span>/></pre>
+ * </div>
+ *
+ * @subsubsection pluginDescPlugin plugin
+ *
+ * This is the top level element of the plug-in descriptor. It can have
+ * following attributes.
+ *
+ * - @a id: A mandatory unique identifier for the plug-in. Plug-in identifiers
+ * should preferably be generated using a reversed DNS domain name as
+ * prefix to prevent identifier conflicts.
+ * - @a name: An optional human-readable name for the plug-in.
+ * - @a version: An optional version number for the plug-in. Version numbers
+ * are used for checking compatibility when resolving versioned plug-in
+ * dependencies. See also information about
+ * @ref pluginVersions "plug-in versions".
+ * - @a provider-name: The name of the plug-in provider or author. Optional.
+ *
+ * This element can contain following elements.
+ *
+ * - @ref pluginDescPluginBWC "backwards-compatibility": Optional information about backwards
+ * compatibility of this plug-in version.
+ * - @ref pluginDescPluginRequires "requires": Information about static plug-in dependencies. Can be omitted
+ * if the plug-in does not have static dependencies.
+ * - @ref pluginDescPluginRuntime "runtime": Information about the plug-in runtime library. Can be omitted
+ * if the plug-in does not have a runtime library but only data.
+ * - @ref pluginDescPluginEP "extension-point": Information about extension points provided by the
+ * plug-in. This element is repeated if there are multiple extension points
+ * and omitted if there are none.
+ * - @ref pluginDescPluginE "extension": Information about extensions provided by the plug-in.
+ * This element is repeated if there are multiple extensions and omitted
+ * if there are none.
+ *
+ * @subsubsection pluginDescPluginBWC backwards-compatibility
+ *
+ * This element includes optional information about the backwards compatibility
+ * of this plug-in version. It can have following attributes.
+ *
+ * - @a abi: Backwards compatibility of the application binary interface (ABI)
+ * of the plug-in. ABI includes any public symbols exported by the plug-in,
+ * data structures associated with exported symbols and any extension points
+ * provided by the plug-in. The ABI of the current plug-in version is
+ * backwards compatible with any plug-in version from the version specified
+ * here to the current version. This information is used when resolving
+ * versioned plug-in dependencies. See also information about
+ * @ref pluginVersions "plug-in versions".
+ * - @a api: Backwards compatibility of the application programming interface
+ * (API) of the plug-in. API compatibility means that source code developed
+ * against one version of the plug-in also compiles against another version
+ * of the plug-in. This information is not used by framework but it can be
+ * used by a developer developing dependent plug-ins.
+ *
+ * These apply to plug-ins that provide header files and runtime libraries.
+ * For example, a plug-in might export global functions to other plug-ins or it
+ * might provide an extension point where an extension installed by other
+ * plug-in must conform to data structures defined by the plug-in.
+ * Both attributes are optional.
+ *
+ * @subsubsection pluginDescPluginRequires requires
+ *
+ * This element includes information about static plug-in dependencies.
+ * It can be omitted if there are no dependencies. It can contain following
+ * elements.
+ *
+ * - @ref pluginDescPluginReqCP "c-pluff": An optional version dependency
+ * on the C-Pluff implementation.
+ * - @ref pluginDescPluginReqImport "import": Declares a static dependency
+ * on other plug-in. This element is repeated if there are multiple
+ * dependencies and omitted if there are none.
+ *
+ * @subsubsection pluginDescPluginReqCP c-pluff
+ *
+ * This element declares a version dependency on the C-Pluff
+ * implementation. It can be used to ensure that the plug-in is not loaded by
+ * incompatible C-Pluff version. It has the following attribute.
+ *
+ * - @a version: The required version of the C-Pluff implementation.
+ * This is used when resolving the plug-in. It is checked that the used
+ * C-Pluff implementation is backwards compatible with the version specified
+ * here when it comes to the application binary interface (ABI) of C-Pluff.
+ *
+ * @subsubsection pluginDescPluginReqImport import
+ *
+ * This element declares a static dependency on other plug-in. It must be
+ * used when a plug-in uses global symbols or data from other plug-in or when
+ * a plug-in uses an extension point defined by other plug-in or whenever some
+ * other plug-in needs to be there for the plug-in to work. The framework takes
+ * care of resolving and starting the dependencies whenever the plug-in is
+ * resolved or started.
+ *
+ * This element can have following attributes.
+ *
+ * - @a plugin: The identifier of the imported plug-in.
+ * - @a version: An optional version dependency on the imported plug-in.
+ * The plug-in can be resolved only if the version of the imported plug-in
+ * is backwards compatible with the version specified here when it comes
+ * to the application binary interface (ABI) of the imported plug-in.
+ * - @a optional: Is the import optional or not ("true" or "false"). Default is
+ * false, a mandatory import.
+ * An optional import behaves just like the mandatory import as long as the
+ * imported plug-in is present. However, if it is not present then the
+ * import is ignored. Optional import can be used if the plug-in works
+ * in limited capacity even without the specified plug-in.
+ *
+ * @subsubsection pluginDescPluginRuntime runtime
+ *
+ * This element contains information about the plug-in runtime library. It is
+ * omitted if the plug-in does not have a runtime library but contains only
+ * data. It can have following attributes.
+ *
+ * - @a library: The name of the plug-in runtime library in the plug-in
+ * directory. A platform specific extension (for example, ".so" or ".dll")
+ * is added to the value specified here when loading the library.
+ * - @a funcs: The functions to be used to create an instance of the plug-in
+ * runtime. This attribute is optional. It is needed if the plug-in has
+ * a start or stop function. The value specified here is a name of an
+ * exported symbol which contains a pointer to @ref cp_plugin_runtime_t
+ * structure.
+ *
+ * @subsubsection pluginDescPluginEP extension-point
+ *
+ * This element defines an extension point provided by the plug-in.
+ * It can have following attributes.
+ *
+ * - @a id: The local identifier of the extension point. The value specified
+ * here is prefixed with the identifier of the plug-in and dot to construct
+ * the global identifier of the extension point.
+ * - @a name: An optional human-readable name describing the use of the
+ * extension point.
+ * - @a schema: An optional path to the extension point XML schema in
+ * the plug-in directory. This information is not currently used by the
+ * framework. But it can be used by a developer to determine what information
+ * should be provided by extensions attached to this extension point.
+ *
+ * @subsubsection pluginDescPluginE extension
+ *
+ * This element defines an extension installed into a specified extension
+ * point provided by the defining plug-in or some other plug-in.
+ * It can have following attributes.
+ *
+ * - @a point: The global identifier of the associated extension point.
+ * - @a id: An optional local identifier for the extension. The value specified
+ * here is prefixed with the identifier of the plug-in and dot to construct
+ * the global identifier for the extension.
+ * - @a name: An optional human-readable name describing the extension.
+ *
+ * The extension element can contain XML elements specific to the associated
+ * extension point (conforming to the schema defined by the extension point).
+ *
+ * @subsection pluginRuntime Plug-in runtime library
+ *
+ * A plug-in runtime library is an optional plug-in element. Plug-ins only
+ * supplying static data in form of XML data and files do not need a runtime
+ * library. However, a typical plug-in does provide program logic as well.
+ *
+ * The plug-in runtime library includes all program logic and program
+ * data provided by the plug-in. It is simply a shared library, or a
+ * dynamically linked library, which is linked in to the application when
+ * the plug-in is started. When plug-in is unloaded, the runtime library is
+ * unloaded as well. The framework has been designed to manage dependencies
+ * so that unloading of the runtime library does not cause problems, provided
+ * that plug-ins behave properly.
+ *
+ * A plug-in can expose functionality to other plug-ins either as exported
+ * global symbols that are directly resolved by other plug-ins or by supplying
+ * extensions. When other plug-ins are directly using exported symbols the
+ * plug-in acts just like any standard shared library. Nothing special there.
+ * The more interesting case is exposing functionality as extensions. Because
+ * the extension is registered at a specific extension point, the logic in
+ * other plug-ins can use the extension and the associated program logic even
+ * if they are not aware of the existence of the extension supplying plug-in.
+ *
+ * The extension points accepting program logic as extensions define a way
+ * to specify the name of the symbol pointing to the supplied logic. This is
+ * typically an attribute of an XML element contained in the extension
+ * definition. The plug-in supplying the extension can then export the program
+ * logic as a global symbol with arbitrary name and then place the name of the
+ * symbol in extension data. Alternatively, the plug-in can define a virtual
+ * symbol at runtime using ::cp_define_symbol. Other plug-ins that are using
+ * extensions registered at the extension point can then resolve the named
+ * symbol using ::cp_resolve_symbol at runtime. The framework automatically
+ * creates a dependency from the symbol using plug-in to the symbol supplying
+ * plug-in to prevent failures in case the symbol supplying plug-in is stopped
+ * or unloaded.
+ *
+ * @subsection pluginData Static plug-in data
+ *
+ * Plug-in can supply static data to other plug-ins using at least two
+ * different mechanisms. A plug-in can easily provide static XML data as part
+ * of extension elements. Additionally, a plug-in directory can contain
+ * files that may be accessed by other plug-ins. Currently the platform does
+ * not provide assistance in accessing data files provided by other plug-ins.
+ * However, a plug-in can locate the plug-in directory and thus any included
+ * data files by using plug-in path available in @ref cp_plugin_info_t
+ * structure of the data providing plug-in.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl default (if it is not specified or empty) is 'no-libtool'.
+dnl INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl depending on --{enable,disable}-{shared,static} and on the presence of
+dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl implementations (in libc or libintl) without the ngettext() function
+dnl will be ignored. If NEEDSYMBOL is specified and is
+dnl 'need-formatstring-macros', then GNU gettext implementations that don't
+dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries. If empty,
+dnl the value `$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl and used.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl Catalog format: none
+dnl Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+ // Memory pool
+
+ //! This class is used by the parser to create new nodes and attributes, without overheads of dynamic memory allocation.
+ //! In most cases, you will not need to use this class directly.
+ //! However, if you need to create nodes manually or modify names/values of nodes,
+ //! you are encouraged to use memory_pool of relevant xml_document to allocate the memory.
+ //! Not only is this faster than allocating them by using <code>new</code> operator,
+ //! but also their lifetime will be tied to the lifetime of document,
+ //! possibly simplyfing memory management.
+ //! <br><br>
+ //! Call allocate_node() or allocate_attribute() functions to obtain new nodes or attributes from the pool.
+ //! You can also call allocate_string() function to allocate strings.
+ //! Such strings can then be used as names or values of nodes without worrying about their lifetime.
+ //! Note that there is no <code>free()</code> function -- all allocations are freed at once when clear() function is called,
+ //! or when the pool is destroyed.
+ //! <br><br>
+ //! It is also possible to create a standalone memory_pool, and use it
+ //! to allocate nodes, whose lifetime will not be tied to any document.
+ //! <br><br>
+ //! Pool maintains <code>RAPIDXML_STATIC_POOL_SIZE</code> bytes of statically allocated memory.
+ //! Until static memory is exhausted, no dynamic memory allocations are done.
+ //! When static memory is exhausted, pool allocates additional blocks of memory of size <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> each,
+ //! by using global <code>new[]</code> and <code>delete[]</code> operators.
+ //! This behaviour can be changed by setting custom allocation routines.
+ //! Use set_allocator() function to set them.
+ //! <br><br>
+ //! Allocations for nodes, attributes and strings are aligned at <code>RAPIDXML_ALIGNMENT</code> bytes.
+ //! This value defaults to the size of pointer on target architecture.
+ //! <br><br>
+ //! To obtain absolutely top performance from the parser,
+ //! it is important that all nodes are allocated from a single, contiguous block of memory.
+ //! Otherwise, cache misses when jumping between two (or more) disjoint blocks of memory can slow down parsing quite considerably.
+ //! If required, you can tweak <code>RAPIDXML_STATIC_POOL_SIZE</code>, <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> and <code>RAPIDXML_ALIGNMENT</code>

+WITH_BRIDGE:=yes

+# Comment out to remove persistent database support from the broker. This

+WITH_PERSISTENCE:=yes

+ * taken place. An attempt will be made to write the network data, but if the
+ * socket is not available for writing at that time then the packet will not be
+ * sent. To ensure the packet is sent, call mosquitto_loop() (which must also
+ * be called to process incoming network data).
+ * This is especially important when disconnecting a client that has a will. If
+ * the broker does not receive the DISCONNECT command, it will assume that the
+ * client has disconnected unexpectedly and send the will.

+
+ This is the main class for use communicating with an MQTT broker.
+
+ General usage flow:
+
+ * Use connect()/connect_async() to connect to a broker
+ * Call loop() frequently to maintain network traffic flow with the broker
+ * Or use loop_start() to set a thread running to call loop() for you.
+ * Or use loop_forever() to handle calling loop() for you in a blocking
+ * function.
+ * Use subscribe() to subscribe to a topic and receive messages
+ * Use publish() to send messages
+ * Use disconnect() to disconnect from the broker
+
+ Data returned from the broker is made available with the use of callback
+ functions as described below.
+
+ Callbacks
+ =========
+
+ A number of callback functions are available to receive data back from the
+ broker. To use a callback, define a function and then assign it to the
+ client:
+
+ def on_connect(mosq, userdata, rc):
+ print("Connection returned " + str(rc))
+
+ client.on_connect = on_connect
+
+ All of the callbacks as described below have a "mosq" and an "userdata"
+ argument. "mosq" is the Mosquitto instance that is calling the callback.
+ "userdata" is user data of any type and can be set when creating a new
+ client instance or with user_data_set(userdata).
+
+ The callbacks:
+
+ on_connect(mosq, userdata, rc): called when the broker responds to our
+ connection request. The value of rc determines success or not:
+ 0: Connection successful
+ 1: Connection refused - incorrect protocol version
+ 2: Connection refused - invalid client identifier
+ 3: Connection refused - server unavailable
+ 4: Connection refused - bad username or password
+ 5: Connection refused - not authorised
+ 6-255: Currently unused.
+
+ on_disconnect(mosq, userdata, rc): called when the client disconnects from
+ the broker. The rc parameter indicates the disconnection state. If
+ MOSQ_ERR_SUCCESS (0), the callback was called in response to a
+ disconnect() call. If any other value the disconnection was unexpected,
+ such as might be caused by a network error.
+
+ on_message(mosq, userdata, message): called when a message has been
+ received on a topic that the client subscribes to. The message variable
+ is a MosquittoMessage that describes all of the message parameters.
+
+ on_publish(mosq, userdata, mid): called when a message that was to be sent
+ using the publish() call has completed transmission to the broker. For
+ messages with QoS levels 1 and 2, this means that the appropriate
+ handshakes have completed. For QoS 0, this simply means that the message
+ has left the client. The mid variable matches the mid variable returned
+ from the corresponding publish() call, to allow outgoing messages to be
+ tracked. This callback is important because even if the publish() call
+ returns success, it does not always mean that the message has been sent.
+
+ on_subscribe(mosq, userdata, mid, granted_qos): called when the broker
+ responds to a subscribe request. The mid variable matches the mid
+ variable returned from the corresponding subscribe() call. The
+ granted_qos variable is a list of integers that give the QoS level the
+ broker has granted for each of the different subscription requests.
+
+ on_unsubscribe(mosq, userdata, mid): called when the broker responds to an
+ unsubscribe request. The mid variable matches the mid variable returned
+ from the corresponding unsubscribe() call.
+
+ on_log(mosq, userdata, level, buf): called when the client has log
+ information. Define to allow debugging. The level variable gives the
+ severity of the message and will be one of MOSQ_LOG_INFO,
+ MOSQ_LOG_NOTICE, MOSQ_LOG_WARNING, MOSQ_LOG_ERR, and MOSQ_LOG_DEBUG. The
+ message itself is in buf.

+ broker. If client_id is zero length or None, then one will be randomly
+ generated. In this case, clean_session must be True. If this is not the
+ case a ValueError will be raised.
+
+ clean_session is a boolean that determines the client type. If True,
+ the broker will remove all information about this client when it
+ disconnects. If False, the client is a persistent client and
+ subscription information and queued messages will be retained when the
+ client disconnects.
+ Note that a client will never discard its own outgoing messages on
+ disconnect. Calling connect() or reconnect() will cause the messages to
+ be resent. Use reinitialise() to reset a client to its original state.

+ * The following functions that deal with network operations will return
+ * MOSQ_ERR_SUCCESS on success, but this does not mean that the operation has
+ * taken place. An attempt will be made to write the network data, but if the
+ * socket is not available for writing at that time then the packet will not be
+ * sent. To ensure the packet is sent, call mosquitto_loop() (which must also
+ * be called to process incoming network data).
+ * This is especially important when disconnecting a client that has a will. If
+ * the broker does not receive the DISCONNECT command, it will assume that the
+ * client has disconnected unexpectedly and send the will.

+
+ This is the main class for use communicating with an MQTT broker.
+
+ General usage flow:
+
+ * Use connect()/connect_async() to connect to a broker
+ * Call loop() frequently to maintain network traffic flow with the broker
+ * Or use loop_start() to set a thread running to call loop() for you.
+ * Or use loop_forever() to handle calling loop() for you in a blocking
+ * function.
+ * Use subscribe() to subscribe to a topic and receive messages
+ * Use publish() to send messages
+ * Use disconnect() to disconnect from the broker
+
+ Data returned from the broker is made available with the use of callback
+ functions as described below.
+
+ Callbacks
+ =========
+
+ A number of callback functions are available to receive data back from the
+ broker. To use a callback, define a function and then assign it to the
+ client:
+
+ def on_connect(mosq, userdata, rc):
+ print("Connection returned " + str(rc))
+
+ client.on_connect = on_connect
+
+ All of the callbacks as described below have a "mosq" and an "userdata"
+ argument. "mosq" is the Mosquitto instance that is calling the callback.
+ "userdata" is user data of any type and can be set when creating a new
+ client instance or with user_data_set(userdata).
+
+ The callbacks:
+
+ on_connect(mosq, userdata, rc): called when the broker responds to our
+ connection request. The value of rc determines success or not:
+ 0: Connection successful
+ 1: Connection refused - incorrect protocol version
+ 2: Connection refused - invalid client identifier
+ 3: Connection refused - server unavailable
+ 4: Connection refused - bad username or password
+ 5: Connection refused - not authorised
+ 6-255: Currently unused.
+
+ on_disconnect(mosq, userdata, rc): called when the client disconnects from
+ the broker. The rc parameter indicates the disconnection state. If
+ MOSQ_ERR_SUCCESS (0), the callback was called in response to a
+ disconnect() call. If any other value the disconnection was unexpected,
+ such as might be caused by a network error.
+
+ on_message(mosq, userdata, message): called when a message has been
+ received on a topic that the client subscribes to. The message variable
+ is a MosquittoMessage that describes all of the message parameters.
+
+ on_publish(mosq, userdata, mid): called when a message that was to be sent
+ using the publish() call has completed transmission to the broker. For
+ messages with QoS levels 1 and 2, this means that the appropriate
+ handshakes have completed. For QoS 0, this simply means that the message
+ has left the client. The mid variable matches the mid variable returned
+ from the corresponding publish() call, to allow outgoing messages to be
+ tracked. This callback is important because even if the publish() call
+ returns success, it does not always mean that the message has been sent.
+
+ on_subscribe(mosq, userdata, mid, granted_qos): called when the broker
+ responds to a subscribe request. The mid variable matches the mid
+ variable returned from the corresponding subscribe() call. The
+ granted_qos variable is a list of integers that give the QoS level the
+ broker has granted for each of the different subscription requests.
+
+ on_unsubscribe(mosq, userdata, mid): called when the broker responds to an
+ unsubscribe request. The mid variable matches the mid variable returned
+ from the corresponding unsubscribe() call.
+
+ on_log(mosq, userdata, level, buf): called when the client has log
+ information. Define to allow debugging. The level variable gives the
+ severity of the message and will be one of MOSQ_LOG_INFO,
+ MOSQ_LOG_NOTICE, MOSQ_LOG_WARNING, MOSQ_LOG_ERR, and MOSQ_LOG_DEBUG. The
+ message itself is in buf.

+ broker. If client_id is zero length or None, then one will be randomly
+ generated. In this case, clean_session must be True. If this is not the
+ case a ValueError will be raised.
+
+ clean_session is a boolean that determines the client type. If True,
+ the broker will remove all information about this client when it
+ disconnects. If False, the client is a persistent client and
+ subscription information and queued messages will be retained when the
+ client disconnects.
+ Note that a client will never discard its own outgoing messages on
+ disconnect. Calling connect() or reconnect() will cause the messages to

+
+This guide will help you setup your developing environment for Protocol plug-in Manager and Protocol plug-ins in Ubuntu.
+
+1. Preparings
+Before starting, following tools should be installed.
+
+Automake
+Automake is a tool for automatically generating Makefile.in files compiliant with the GNU Coding Standards. This tool is used for compiling C-Pluff open source which used in Plug-in Manager.
+$ sudo apt-get install automake
+
+Libtool
+GNU libtool is a generic library support script. This tool is used for compiling C-Pluff open source which used in Plug-in Manager.
+ $ sudo apt-get install libtool
+
+gettext
+GNU `gettext' utilities are a set of tools that provides a framework to help other GNU packages produce multi-lingual messages. This tool is used for compiling C-Pluff open source which used in Plug-in Manager.
+ $ sudo apt-get install gettext
+
+Expat
+Expat is a stream-oriented XML parser library. This library is used for compiling C-Pluff open source which used in Plug-in Manager.
+ $ sudo apt-get install expat
+
+Building and Using Protocol Plug-in Manager
+
+Once the source code is downloaded into a specific folder, oic in this context, you may follow the steps to build and execute Protocol Plug-in Manager.
+The path for Protocol Plugin is as following;
+
+~/oic/oic-resource/service/protocol-plugin $_
+
+
+The Protocol Plug-in directory includes following sub directories;
+
+/plugin-manager Directory for Plug-in Manager
+/plugins Directory for Reference Plugins
+/lib Directory for Common Library
+/sample-app Directory for Iotivity Sample Application
+/doc Directory for Developers Document
+/build Directory for Building and Binary Release
+
+
+If you build by scons skip 2,3.
+
+2. Compiling C-Pluff library
+Before building Protocol-Plugin Manager, C-Pluff library should be compiled as follows.
+
+~/service/protocol-plugin/lib/cpluff$ aclocal
+~/service/protocol-plugin/lib/cpluff$ autoconf
+~/service/protocol-plugin/lib/cpluff$ autoheader
+~/service/protocol-plugin/lib/cpluff$ automake
+~/service/protocol-plugin/lib/cpluff$ ./configure
+~/service/protocol-plugin/lib/cpluff$ make
+
+
+3. Run make
+By running make in the protocol-plugin path, protocol-plugin manager, all plugins and sample applications will be created.
+
+NOTE: To build plugins in 64-bit Ubuntu Linux, OCLib.a and libcoap.a library should be re-compiled with ?fPIC option.
+
+~/service/protocol-plugin/build/linux$make
+
+
+4. Using Plugins
+This version of protocol plug-in source code has following functionality.
+
+1) Provides plug-in manager which can start and stop plug-in library.
+2) Provides plug-in library which can communicate with MQTT protocol Fan and Light.
+3) Locate shared plug-in library and XML file in a specific folder.
+
+So, to test a plug-in, follow below steps.
+
+1) Copy libpmimple.so from {Top_Dir}/out/linux/x86/release to sample-app folder.
+2) Provides OIC Sample Client which can get info about Fan and Light with configuration file(pluginmanager.xml).
+3) Copy the pluginmanager.xml from ~/service/protocol-plugin/sample-app/linux/mqtt/ to sample-app folder.
+4) Modifty the pluginmanager.xml
+5) Before starting sample app need as below command.
+ $export LD_LIBRARY_PATH={Top_Dir}/out/linux/x86/release/:$LD_LIBRARY_PATH
+6) Start the plug-in from plug-in manager sample.
+ ex)~service/protocol-plugin/sample-app/linux/mqtt$./mqttclient
+ (Need mqtt broker working in the local system(127.0.0.1) for test.)

+===============================================================================
+== How to Build SoftSensorManager ==
+===============================================================================
+
+Once the source code is downloaded in your local specific folder, you may follow
+the steps to build and execute Soft Sensor Manager and its applications.
+In this context, we assume that the code was downloaded into 'oic' folder.
+
+
+=======================================
+1. Download source code
+=======================================
+
+Once you download the codes, please make sure that the downloaded code structure is as follows;
+
+oic/resource
+oic/service
+oic/utilities
+
+
+The path for Soft Sensor Manager is as following;
+
+oic/service/soft-sensor-manager
+
+The SoftSensorManager directory includes following sub directories;
+
+Directories Description
+oic/service/soft-sensor-manager/build : There are makefiles for different platform; Linux, Tizen, and Arduino.
+oic/service/soft-sensor-manager/doc : SSM developer's guide and Getting started documents
+oic/service/soft-sensor-manager/SampleApp : There are two types of sample applications; application for UI, and application for physical sensors.
+ For UI application, there are SSMTesterApp in /linux, and /Tizen.
+ For physical sensors,
+ 1) Temperature and Humidity sensors, THSensorApp, in \linux and \arduino.
+ In the two directories, in \linux and \arduino , there are two TemperaterHumiditySensor applications,
+ THSensorApp and THSensorApp1, and they are for DiscomfortSoftSensor which aggregates
+ two TemperaterHumiditySensors to calculate current discomfort index in the given room.
+ 2) Trackee_Thing for IndoorTrajectorySensor in \linux and \arduino
+
+oic/service/soft-sensor-manager/SDK : The SDK APIs for applications is located.
+oic/service/soft-sensor-manager/SSMCore : The SSM service codes
+oic/service/soft-sensor-manager/SoftSensorPlugin : The source codes for soft sensors can be located in this folder.
+ Examples of soft sensors are DiscomfortIndexSensor and IndoorTrajectorySensor.
+
+
+=======================================
+2. Refer readme files in each build
+ directory for each module.
+=======================================
+There are readme files in the build directories for each module (e.g. \SDK, \ SSMCore, \SampleApp).
+Please refer the files for specific setup.
+
+
+=======================================
+3. Run make
+=======================================
+
+3.1 Run make for SoftSensorManager & App in Ubuntu.
+
+3.1.1 Before running make for SoftSensorManager & App in Ubuntu, resource should be built in advance.
+ Please refer to ¡®Build the IoTivity project for Linux¡¯ in previous section
+
+3.1.2 If you type "make" at ¡°soft-sensor-manager/build/linux¡±, all packages will be pushed to "/soft-sensor-manager/build/linux/release".
+ You can also found other packages in the folder
+
++--------------------------------------------------------------+
+| ~/oic/service/soft-sensor-manager/build/linux$ make |
++--------------------------------------------------------------+
+
+3.2 Run make for App in Arduino
+
+3.2.1 If you want to build for Arduino, download Arduino IDE (Arduino 1.0.6) from following url.
+ Extract ¡®arduino-1.0.6-linux32.tgz¡¯ and change folder name from ¡®arduino-1.0.6¡¯ to ¡®arduino¡¯ and then move to "/usr/share/".
+ url: http://arduino.cc/en/Main/Software
+
++--------------------------------------------------------------------+
+| $ mv arduino-1.0.6 arduino |
+| $ sudo cp -Rdp ./arduino /usr/share/ |
++--------------------------------------------------------------------+
+
+3.2.2 Download Time library (Time.zip, Click ¡°The download¡±) from following url.
+ Unzip Time.zip and move them to /usr/share/arduino/libraries.
+ url: http://playground.arduino.cc/Code/Time
+
++--------------------------------------------------------------------+
+| $ sudo cp -Rdp ./Time /usr/share/arduino/libraries/ |
++--------------------------------------------------------------------+
+
+3.2.3 Create file named ¡®local.properties¡¯ in ¡°/oic/resource/csdk/¡± with the following definitions.
+
++------------------------------------------------------------------------------------+
+| < local.properties > |
+| ARDUINO_DIR = /usr/share/arduino |
+| ARDUINO_TOOLS_DIR = $(ARDUINO_DIR)/hardware/tools/avr/bin |
++------------------------------------------------------------------------------------+
+ If you have a problem with compiling ¡®resource¡¯ when you compile arduino application,
+ you may need to check 'local.properties' which is written in the readme file, '/oic/resource/csdk/README'.
+
+3.2.4 Before running make for application, you need to build resource with arduino platform first.
+ Please refer to below example.
+
++------------------------------------------------------------------------------------------+
+| ~/oic/resource/csdk$ make PLATFORM=arduinomega ARDUINOWIFI=1 |
++------------------------------------------------------------------------------------------+
+ PLATFORM : arduinomega or arduinodue.
+ ARDUINOWIFI : 0 (Ethernet), 1(Wifi)
+
+3.2.5 Now, you are ready to build sample arduino application.
+ To build all sample applications for arduino, just do as below.
+
++------------------------------------------------------------------------------------------------+
+|~/oic/service/soft-sensor-manager/ build/Arduino$ make PLATFORM=arduinomega ARDUINOWIFI=1 |
++------------------------------------------------------------------------------------------------+
+
+ If you want to build each sample application separately, go to build directory for sample application.
+ Belowing is example for THSensor App.
+
++-------------------------------------------------------------------------------------------------------------------+
+|~/oic/service/soft-sensor-manager/SampleApp/arduino/THSensorApp/build$ make PLATFORM=arduinomega ARDUINOWIFI=1 |
++-------------------------------------------------------------------------------------------------------------------+
+
+3.2.6. To build and deploy the binary into the target hardware board, Aruino in this case, you need 'install' option.
+ Please refer to below example for THSensorApp;
+
++--------------------------------------------------------------------------------------------------------------------------+
+|~/oic/service/soft-sensor-manager/SampleApp/arduino/THSensorApp/build$ make install PLATFORM=arduinomega ARDUINOWIFI=1 |
++--------------------------------------------------------------------------------------------------------------------------+
+ Before ¡®make install¡¯, you need to check the file located at "/oic/service/soft-sensor-manager/SampleApp/arduino/THSensorApp/build/Makefile".
+ Line 26, ARDUINO_PORT is the serial port path, which has to be aligned on your system.
+
+
+=======================================
+4. Execute THSensorApp and SSMTesterApp
+=======================================
+
+If you want to check how soft-sensor-manager is working, you can run simple applications - THSensorApp and SSMTesterApp
+
+4.1 To initiate THSensorApp, please enter as following;
+
++------------------------------------------------------------------------+
+|~/oic/service/soft-sensor-manager/build/linux/release$ ./THSensorApp |
+|~/oic/service/soft-sensor-manager/build/linux/release$ ./THSensorApp1 |
++------------------------------------------------------------------------+
+
+4.2 To initiate SSMTesterApp, please enter as following;
+
++--------------------------------------------------------------------------+
+|~/oic/service/soft-sensor-manager/build/linux/release$ ./SSMTesterApp |
++--------------------------------------------------------------------------+
+
+Note that the sequence of process initiations should be followed due to the process dependencies.
+
+
+=======================================
+5. Build with SCons
+=======================================
+
+If you want to use Scons to build soft-sensor-manager, build the source code and execute sample applications as following steps.
+
+5.1 After downloading the source codes, type "scons" at project root directory "oic/"
+
++---------------------------------------+
+|~/oic$ scons |
++---------------------------------------+
+
+5.2 To execute Soft Sensor Manager and its applications, some shared libraries must be exported.
+
+5.2.1 Go to "oic/out/<target_os>/<target_arch>/release", and check if there are following .so files
+ liboc.so
+ liboctbstack.so
+ liboc_logger.so
+
+5.2.2 To export the shared libraries, please enter as following;
+
++---------------------------------------------------------------------------------------------------------------------------+
+|~/oic/out/<target_os>/<target_arch>/release$ export LD_LIBRARY_PATH=~/oic/out/<target_os>/<target_arch>/release |
++---------------------------------------------------------------------------------------------------------------------------+
+
+5.3 Generated outputs from building soft-sensor-manager will be in "oic/out/<target_os>/<target_arch>/release/service/soft-sensor-manager".
+
+5.4 To initiate THSensorApp, please enter as following;
+
++------------------------------------------------------------------------------------------+
+|~/oic/out/<target_os>/<target_arch>/release/service/soft-sensor-manager$ ./THSensorApp |
+|~/oic/out/<target_os>/<target_arch>/release/service/soft-sensor-manager$ ./THSensorApp1 |
++------------------------------------------------------------------------------------------+
+
+5.5 To initiate SSMTesterApp, please enter as following;
+
++--------------------------------------------------------------------------------------------+
+|~/oic/out/<target_os>/<target_arch>/release/service/soft-sensor-manager$ ./SSMTesterApp |

+ // Memory pool
+
+ //! This class is used by the parser to create new nodes and attributes, without overheads of dynamic memory allocation.
+ //! In most cases, you will not need to use this class directly.
+ //! However, if you need to create nodes manually or modify names/values of nodes,
+ //! you are encouraged to use memory_pool of relevant xml_document to allocate the memory.
+ //! Not only is this faster than allocating them by using <code>new</code> operator,
+ //! but also their lifetime will be tied to the lifetime of document,
+ //! possibly simplyfing memory management.
+ //! <br><br>
+ //! Call allocate_node() or allocate_attribute() functions to obtain new nodes or attributes from the pool.
+ //! You can also call allocate_string() function to allocate strings.
+ //! Such strings can then be used as names or values of nodes without worrying about their lifetime.
+ //! Note that there is no <code>free()</code> function -- all allocations are freed at once when clear() function is called,
+ //! or when the pool is destroyed.
+ //! <br><br>
+ //! It is also possible to create a standalone memory_pool, and use it
+ //! to allocate nodes, whose lifetime will not be tied to any document.
+ //! <br><br>
+ //! Pool maintains <code>RAPIDXML_STATIC_POOL_SIZE</code> bytes of statically allocated memory.
+ //! Until static memory is exhausted, no dynamic memory allocations are done.
+ //! When static memory is exhausted, pool allocates additional blocks of memory of size <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> each,
+ //! by using global <code>new[]</code> and <code>delete[]</code> operators.
+ //! This behaviour can be changed by setting custom allocation routines.
+ //! Use set_allocator() function to set them.
+ //! <br><br>
+ //! Allocations for nodes, attributes and strings are aligned at <code>RAPIDXML_ALIGNMENT</code> bytes.
+ //! This value defaults to the size of pointer on target architecture.
+ //! <br><br>
+ //! To obtain absolutely top performance from the parser,
+ //! it is important that all nodes are allocated from a single, contiguous block of memory.
+ //! Otherwise, cache misses when jumping between two (or more) disjoint blocks of memory can slow down parsing quite considerably.
+ //! If required, you can tweak <code>RAPIDXML_STATIC_POOL_SIZE</code>, <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> and <code>RAPIDXML_ALIGNMENT</code>

+** The SQLITE_IOCAP_ATOMIC property means that all writes of

+** CAPI3REF: Standard File Control Opcodes
+**
+** These integer constants are opcodes for the xFileControl method
+** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
+** interface.
+**
+** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging. This
+** opcode causes the xFileControl method to write the current state of
+** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
+** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
+** into an integer that the pArg argument points to. This capability
+** is used during testing and only needs to be supported when SQLITE_TEST
+** is defined.
+** <ul>
+** <li>[[SQLITE_FCNTL_SIZE_HINT]]
+** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
+** layer a hint of how large the database file will grow to be during the
+** current transaction. This hint is not guaranteed to be accurate but it
+** is often close. The underlying VFS might choose to preallocate database
+** file space based on this hint in order to help writes to the database
+** file run faster.
+**
+** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
+** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
+** extends and truncates the database file in chunks of a size specified
+** by the user. The fourth argument to [sqlite3_file_control()] should
+** point to an integer (type int) containing the new chunk-size to use
+** for the nominated database. Allocating database file space in large
+** chunks (say 1MB at a time), may reduce file-system fragmentation and
+** improve performance on some systems.
+**
+** <li>[[SQLITE_FCNTL_FILE_POINTER]]
+** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with a particular database
+** connection. See the [sqlite3_file_control()] documentation for
+** additional information.
+**
+** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
+** ^(The [SQLITE_FCNTL_SYNC_OMITTED] opcode is generated internally by
+** SQLite and sent to all VFSes in place of a call to the xSync method
+** when the database connection has [PRAGMA synchronous] set to OFF.)^
+** Some specialized VFSes need this signal in order to operate correctly
+** when [PRAGMA synchronous | PRAGMA synchronous=OFF] is set, but most
+** VFSes do not need this signal and should silently ignore this opcode.
+** Applications should not call [sqlite3_file_control()] with this
+** opcode as doing so may disrupt the operation of the specialized VFSes
+** that do require it.
+**
+** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
+** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
+** retry counts and intervals for certain disk I/O operations for the
+** windows [VFS] in order to provide robustness in the presence of
+** anti-virus programs. By default, the windows VFS will retry file read,
+** file write, and file delete operations up to 10 times, with a delay
+** of 25 milliseconds before the first retry and with the delay increasing
+** by an additional 25 milliseconds with each subsequent retry. This
+** opcode allows these two values (10 retries and 25 milliseconds of delay)
+** to be adjusted. The values are changed for all database connections
+** within the same process. The argument is a pointer to an array of two
+** integers where the first integer i the new retry count and the second
+** integer is the delay. If either integer is negative, then the setting
+** is not changed but instead the prior value of that setting is written
+** into the array entry, allowing the current retry settings to be
+** interrogated. The zDbName parameter is ignored.
+**
+** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
+** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
+** persistent [WAL | Write Ahead Log] setting. By default, the auxiliary
+** write ahead log and shared memory files used for transaction control
+** are automatically deleted when the latest connection to the database
+** closes. Setting persistent WAL mode causes those files to persist after
+** close. Persisting the files is useful when other processes that do not
+** have write permission on the directory containing the database file want
+** to read the database file, as the WAL and shared memory files must exist
+** in order for the database to be readable. The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
+** WAL mode. If the integer is -1, then it is overwritten with the current
+** WAL persistence setting.
+**
+** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
+** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
+** persistent "powersafe-overwrite" or "PSOW" setting. The PSOW setting
+** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
+** xDeviceCharacteristics methods. The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
+** mode. If the integer is -1, then it is overwritten with the current
+** zero-damage mode setting.
+**
+** <li>[[SQLITE_FCNTL_OVERWRITE]]
+** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
+** a write transaction to indicate that, unless it is rolled back for some
+** reason, the entire database file will be overwritten by the current
+** transaction. This is used by VACUUM operations.
+**
+** <li>[[SQLITE_FCNTL_VFSNAME]]
+** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
+** all [VFSes] in the VFS stack. The names are of all VFS shims and the
+** final bottom-level VFS are written into memory obtained from
+** [sqlite3_malloc()] and the result is stored in the char* variable
+** that the fourth parameter of [sqlite3_file_control()] points to.
+** The caller is responsible for freeing the memory when done. As with
+** all file-control actions, there is no guarantee that this will actually
+** do anything. Callers should initialize the char* variable to a NULL
+** pointer in case this file-control is not implemented. This file-control
+** is intended for diagnostic use only.
+**
+** <li>[[SQLITE_FCNTL_PRAGMA]]
+** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA]
+** file control is sent to the open [sqlite3_file] object corresponding
+** to the database file to which the pragma statement refers. ^The argument
+** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
+** pointers to strings (char**) in which the second element of the array
+** is the name of the pragma and the third element is the argument to the
+** pragma or NULL if the pragma has no argument. ^The handler for an
+** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
+** of the char** argument point to a string obtained from [sqlite3_mprintf()]
+** or the equivalent and that string will become the result of the pragma or
+** the error message if the pragma fails. ^If the
+** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal
+** [PRAGMA] processing continues. ^If the [SQLITE_FCNTL_PRAGMA]
+** file control returns [SQLITE_OK], then the parser assumes that the
+** VFS has handled the PRAGMA itself and the parser generates a no-op
+** prepared statement. ^If the [SQLITE_FCNTL_PRAGMA] file control returns
+** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
+** that the VFS encountered an error while handling the [PRAGMA] and the
+** compilation of the PRAGMA fails with an error. ^The [SQLITE_FCNTL_PRAGMA]
+** file control occurs at the beginning of pragma statement analysis and so
+** it is able to override built-in [PRAGMA] statements.
+**
+** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
+** ^The [SQLITE_FCNTL_BUSYHANDLER]
+** file-control may be invoked by SQLite on the database file handle
+** shortly after it is opened in order to provide a custom VFS with access
+** to the connections busy-handler callback. The argument is of type (void **)
+** - an array of two (void *) values. The first (void *) actually points
+** to a function of type (int (*)(void *)). In order to invoke the connections
+** busy-handler, this function should be invoked with the second (void *) in
+** the array as the only argument. If it returns non-zero, then the operation
+** should be retried. If it returns zero, the custom VFS should abandon the
+** current operation.
+**
+** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
+** ^Application can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
+** to have SQLite generate a
+** temporary filename using the same algorithm that is followed to generate
+** temporary filenames for TEMP tables and other internal uses. The
+** argument should be a char** which will be filled with the filename
+** written into memory obtained from [sqlite3_malloc()]. The caller should
+** invoke [sqlite3_free()] on the result to avoid a memory leak.
+**
+** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
+** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
+** maximum number of bytes that will be used for memory-mapped I/O.
+** The argument is a pointer to a value of type sqlite3_int64 that
+** is an advisory maximum number of bytes in the file to memory map. The
+** pointer is overwritten with the old value. The limit is not changed if
+** the value originally pointed to is negative, and so the current limit
+** can be queried by passing in a pointer to a negative number. This
+** file-control is used internally to implement [PRAGMA mmap_size].

+typedef struct sqlite3_mutex sqlite3_mutex;
+
+/*
+** CAPI3REF: OS Interface Object
+**
+** An instance of the sqlite3_vfs object defines the interface between
+** the SQLite core and the underlying operating system. The "vfs"
+** in the name of the object stands for "virtual file system". See
+** the [VFS | VFS documentation] for further information.
+**
+** The value of the iVersion field is initially 1 but may be larger in
+** future versions of SQLite. Additional fields may be appended to this
+** object when the iVersion value is increased. Note that the structure
+** of the sqlite3_vfs object changes in the transaction between
+** SQLite version 3.5.9 and 3.6.0 and yet the iVersion field was not
+** modified.
+**
+** The szOsFile field is the size of the subclassed [sqlite3_file]
+** structure used by this VFS. mxPathname is the maximum length of
+** a pathname in this VFS.
+**
+** Registered sqlite3_vfs objects are kept on a linked list formed by
+** the pNext pointer. The [sqlite3_vfs_register()]
+** and [sqlite3_vfs_unregister()] interfaces manage this list
+** in a thread-safe way. The [sqlite3_vfs_find()] interface
+** searches the list. Neither the application code nor the VFS
+** implementation should use the pNext pointer.
+**
+** The pNext field is the only field in the sqlite3_vfs
+** structure that SQLite will ever modify. SQLite will only access
+** or modify this field while holding a particular static mutex.
+** The application should never modify anything within the sqlite3_vfs
+** object once the object has been registered.
+**
+** The zName field holds the name of the VFS module. The name must
+** be unique across all VFS modules.
+**
+** [[sqlite3_vfs.xOpen]]
+** ^SQLite guarantees that the zFilename parameter to xOpen
+** is either a NULL pointer or string obtained
+** from xFullPathname() with an optional suffix added.
+** ^If a suffix is added to the zFilename parameter, it will
+** consist of a single "-" character followed by no more than
+** 11 alphanumeric and/or "-" characters.
+** ^SQLite further guarantees that
+** the string will be valid and unchanged until xClose() is
+** called. Because of the previous sentence,
+** the [sqlite3_file] can safely store a pointer to the
+** filename if it needs to remember the filename for some reason.
+** If the zFilename parameter to xOpen is a NULL pointer then xOpen
+** must invent its own temporary name for the file. ^Whenever the
+** xFilename parameter is NULL it will also be the case that the
+** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
+**
+** The flags argument to xOpen() includes all bits set in
+** the flags argument to [sqlite3_open_v2()]. Or if [sqlite3_open()]
+** or [sqlite3_open16()] is used, then flags includes at least
+** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
+** If xOpen() opens a file read-only then it sets *pOutFlags to
+** include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be set.
+**
+** ^(SQLite will also add one of the following flags to the xOpen()
+** call, depending on the object being opened:
+**
+** <ul>
+** <li> [SQLITE_OPEN_MAIN_DB]
+** <li> [SQLITE_OPEN_MAIN_JOURNAL]
+** <li> [SQLITE_OPEN_TEMP_DB]
+** <li> [SQLITE_OPEN_TEMP_JOURNAL]
+** <li> [SQLITE_OPEN_TRANSIENT_DB]
+** <li> [SQLITE_OPEN_SUBJOURNAL]
+** <li> [SQLITE_OPEN_MASTER_JOURNAL]
+** <li> [SQLITE_OPEN_WAL]
+** </ul>)^
+**
+** The file I/O implementation can use the object type flags to
+** change the way it deals with files. For example, an application
+** that does not care about crash recovery or rollback might make
+** the open of a journal file a no-op. Writes to this journal would
+** also be no-ops, and any attempt to read the journal would return
+** SQLITE_IOERR. Or the implementation might recognize that a database
+** file will be doing page-aligned sector reads and writes in a random
+** order and set up its I/O subsystem accordingly.
+**
+** SQLite might also add one of the following flags to the xOpen method:
+**
+** <ul>
+** <li> [SQLITE_OPEN_DELETEONCLOSE]
+** <li> [SQLITE_OPEN_EXCLUSIVE]
+** </ul>
+**
+** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
+** deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE]
+** will be set for TEMP databases and their journals, transient
+** databases, and subjournals.
+**
+** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
+** with the [SQLITE_OPEN_CREATE] flag, which are both directly
+** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
+** API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
+** SQLITE_OPEN_CREATE, is used to indicate that file should always
+** be created, and that it is an error if it already exists.
+** It is <i>not</i> used to indicate the file should be opened
+** for exclusive access.
+**
+** ^At least szOsFile bytes of memory are allocated by SQLite
+** to hold the [sqlite3_file] structure passed as the third
+** argument to xOpen. The xOpen method does not have to
+** allocate the structure; it should just fill it in. Note that
+** the xOpen method must set the sqlite3_file.pMethods to either
+** a valid [sqlite3_io_methods] object or to NULL. xOpen must do
+** this even if the open fails. SQLite expects that the sqlite3_file.pMethods
+** element will be valid after xOpen returns regardless of the success
+** or failure of the xOpen call.
+**
+** [[sqlite3_vfs.xAccess]]
+** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
+** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
+** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
+** to test whether a file is at least readable. The file can be a
+** directory.
+**
+** ^SQLite will always allocate at least mxPathname+1 bytes for the
+** output buffer xFullPathname. The exact size of the output buffer
+** is also passed as a parameter to both methods. If the output buffer
+** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
+** handled as a fatal error by SQLite, vfs implementations should endeavor
+** to prevent this by setting mxPathname to a sufficiently large value.
+**
+** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
+** interfaces are not strictly a part of the filesystem, but they are
+** included in the VFS structure for completeness.
+** The xRandomness() function attempts to return nBytes bytes
+** of good-quality randomness into zOut. The return value is
+** the actual number of bytes of randomness obtained.
+** The xSleep() method causes the calling thread to sleep for at
+** least the number of microseconds given. ^The xCurrentTime()
+** method returns a Julian Day Number for the current date and time as
+** a floating point value.
+** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
+** Day Number multiplied by 86400000 (the number of milliseconds in
+** a 24-hour day).
+** ^SQLite will use the xCurrentTimeInt64() method to get the current
+** date and time if that method is available (if iVersion is 2 or
+** greater and the function pointer is not NULL) and will fall back
+** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
+**
+** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
+** are not used by the SQLite core. These optional interfaces are provided
+** by some VFSes to facilitate testing of the VFS code. By overriding
+** system calls with functions under its control, a test program can
+** simulate faults and error conditions that would otherwise be difficult
+** or impossible to induce. The set of system calls that can be overridden
+** varies from one VFS to another, and from one version of the same VFS to the
+** next. Applications that use these interfaces must be prepared for any
+** or all of these interfaces to be NULL or for their behavior to change
+** from one release to the next. Applications must not attempt to access
+** any of these methods if the iVersion of the VFS is less than 3.

+** single thread. All open [database connections] must be closed and all
+** other SQLite resources must be deallocated prior to invoking
+** sqlite3_shutdown().
+**
+** Among other things, ^sqlite3_initialize() will invoke
+** sqlite3_os_init(). Similarly, ^sqlite3_shutdown()
+** will invoke sqlite3_os_end().
+**
+** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
+** ^If for some reason, sqlite3_initialize() is unable to initialize
+** the library (perhaps it is unable to allocate a needed resource such
+** as a mutex) it returns an [error code] other than [SQLITE_OK].
+**
+** ^The sqlite3_initialize() routine is called internally by many other
+** SQLite interfaces so that an application usually does not need to
+** invoke sqlite3_initialize() directly. For example, [sqlite3_open()]
+** calls sqlite3_initialize() so the SQLite library will be automatically
+** initialized when [sqlite3_open()] is called if it has not be initialized
+** already. ^However, if SQLite is compiled with the [SQLITE_OMIT_AUTOINIT]
+** compile-time option, then the automatic calls to sqlite3_initialize()
+** are omitted and the application must call sqlite3_initialize() directly
+** prior to using any other SQLite interface. For maximum portability,
+** it is recommended that applications always invoke sqlite3_initialize()
+** directly prior to using any other SQLite interface. Future releases
+** of SQLite may require this. In other words, the behavior exhibited
+** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
+** default behavior in some future release of SQLite.
+**
+** The sqlite3_os_init() routine does operating-system specific
+** initialization of the SQLite library. The sqlite3_os_end()
+** routine undoes the effect of sqlite3_os_init(). Typical tasks
+** performed by these routines include allocation or deallocation
+** of static resources, initialization of global variables,
+** setting up a default [sqlite3_vfs] module, or setting up
+** a default configuration using [sqlite3_config()].
+**
+** The application should never invoke either sqlite3_os_init()
+** or sqlite3_os_end() directly. The application should only invoke
+** sqlite3_initialize() and sqlite3_shutdown(). The sqlite3_os_init()
+** interface is called automatically by sqlite3_initialize() and

+** An instance of this object defines the interface between SQLite
+** and low-level memory allocation routines.
+**
+** This object is used in only one place in the SQLite interface.
+** A pointer to an instance of this object is the argument to
+** [sqlite3_config()] when the configuration option is
+** [SQLITE_CONFIG_MALLOC] or [SQLITE_CONFIG_GETMALLOC].
+** By creating an instance of this object
+** and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
+** during configuration, an application can specify an alternative
+** memory allocation subsystem for SQLite to use for all of its
+** dynamic memory needs.
+**
+** Note that SQLite comes with several [built-in memory allocators]
+** that are perfectly adequate for the overwhelming majority of applications
+** and that this object is only useful to a tiny minority of applications
+** with specialized memory allocation requirements. This object is
+** also used during testing of SQLite in order to specify an alternative
+** memory allocator that simulates memory out-of-memory conditions in
+** order to verify that SQLite recovers gracefully from such
+** conditions.
+**
+** The xMalloc, xRealloc, and xFree methods must work like the
+** malloc(), realloc() and free() functions from the standard C library.
+** ^SQLite guarantees that the second argument to
+** xRealloc is always a value returned by a prior call to xRoundup.
+**
+** xSize should return the allocated size of a memory allocation
+** previously obtained from xMalloc or xRealloc. The allocated size
+** is always at least as big as the requested size but may be larger.
+**
+** The xRoundup method returns what would be the allocated size of
+** a memory allocation given a particular requested size. Most memory
+** allocators round up memory allocations at least to the next multiple
+** of 8. Some allocators round up to a larger multiple or to a power of 2.
+** Every memory allocation request coming in through [sqlite3_malloc()]
+** or [sqlite3_realloc()] first calls xRoundup. If xRoundup returns 0,
+** that causes the corresponding memory allocation to fail.
+**
+** The xInit method initializes the memory allocator. (For example,
+** it might allocate any require mutexes or initialize internal data
+** structures. The xShutdown method is invoked (indirectly) by
+** [sqlite3_shutdown()] and should deallocate any resources acquired
+** by xInit. The pAppData pointer is used as the only parameter to
+** xInit and xShutdown.
+**
+** SQLite holds the [SQLITE_MUTEX_STATIC_MASTER] mutex when it invokes
+** the xInit method, so the xInit method need not be threadsafe. The
+** xShutdown method is only called from [sqlite3_shutdown()] so it does
+** not need to be threadsafe either. For all other methods, SQLite
+** holds the [SQLITE_MUTEX_STATIC_MEM] mutex as long as the
+** [SQLITE_CONFIG_MEMSTATUS] configuration option is turned on (which
+** it is by default) and so the methods are automatically serialized.
+** However, if [SQLITE_CONFIG_MEMSTATUS] is disabled, then the other
+** methods must be threadsafe or else make their own arrangements for
+** serialization.
+**
+** SQLite will never invoke xInit() more than once without an intervening

+** CAPI3REF: Convenience Routines For Running Queries
+**
+** This is a legacy interface that is preserved for backwards compatibility.
+** Use of this interface is not recommended.
+**
+** Definition: A <b>result table</b> is memory data structure created by the
+** [sqlite3_get_table()] interface. A result table records the
+** complete query results from one or more queries.
+**
+** The table conceptually has a number of rows and columns. But
+** these numbers are not part of the result table itself. These
+** numbers are obtained separately. Let N be the number of rows
+** and M be the number of columns.
+**
+** A result table is an array of pointers to zero-terminated UTF-8 strings.
+** There are (N+1)*M elements in the array. The first M pointers point
+** to zero-terminated strings that contain the names of the columns.
+** The remaining entries all point to query results. NULL values result
+** in NULL pointers. All other values are in their UTF-8 zero-terminated
+** string representation as returned by [sqlite3_column_text()].
+**
+** A result table might consist of one or more memory allocations.
+** It is not safe to pass a result table directly to [sqlite3_free()].
+** A result table should be deallocated using [sqlite3_free_table()].
+**
+** ^(As an example of the result table format, suppose a query result
+** is as follows:
+**
+** <blockquote><pre>
+** Name | Age
+** -----------------------
+** Alice | 43
+** Bob | 28
+** Cindy | 21
+** </pre></blockquote>
+**
+** There are two column (M==2) and three rows (N==3). Thus the
+** result table has 8 entries. Suppose the result table is stored
+** in an array names azResult. Then azResult holds this content:
+**
+** <blockquote><pre>
+** azResult[0] = "Name";
+** azResult[1] = "Age";
+** azResult[2] = "Alice";
+** azResult[3] = "43";
+** azResult[4] = "Bob";
+** azResult[5] = "28";
+** azResult[6] = "Cindy";
+** azResult[7] = "21";
+** </pre></blockquote>)^
+**
+** ^The sqlite3_get_table() function evaluates one or more
+** semicolon-separated SQL statements in the zero-terminated UTF-8
+** string of its 2nd parameter and returns a result table to the
+** pointer given in its 3rd parameter.
+**
+** After the application has finished with the result from sqlite3_get_table(),
+** it must pass the result table pointer to sqlite3_free_table() in order to
+** release the memory that was malloced. Because of the way the
+** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
+** function must not try to call [sqlite3_free()] directly. Only
+** [sqlite3_free_table()] is able to release the memory properly and safely.
+**
+** The sqlite3_get_table() interface is implemented as a wrapper around

+**
+** ^(The sqlite3_snprintf() routine is similar to "snprintf()" from
+** the standard C library. The result is written into the
+** buffer supplied as the second parameter whose size is given by
+** the first parameter. Note that the order of the
+** first two parameters is reversed from snprintf().)^ This is an
+** historical accident that cannot be fixed without breaking
+** backwards compatibility. ^(Note also that sqlite3_snprintf()
+** returns a pointer to its buffer instead of the number of
+** characters actually written into the buffer.)^ We admit that
+** the number of characters written would be a more useful return
+** value but we cannot change the implementation of sqlite3_snprintf()
+** now without breaking compatibility.
+**
+** ^As long as the buffer size is greater than zero, sqlite3_snprintf()
+** guarantees that the buffer is always zero-terminated. ^The first
+** parameter "n" is the total size of the buffer, including space for
+** the zero terminator. So the longest string that can be completely
+** written will be n-1 characters.
+**
+** ^The sqlite3_vsnprintf() routine is a varargs version of sqlite3_snprintf().
+**
+** These routines all implement some additional formatting
+** options that are useful for constructing SQL statements.
+** All of the usual printf() formatting options apply. In addition, there
+** is are "%q", "%Q", and "%z" options.
+**
+** ^(The %q option works like %s in that it substitutes a nul-terminated
+** string from the argument list. But %q also doubles every '\'' character.
+** %q is designed for use inside a string literal.)^ By doubling each '\''
+** character it escapes that character and allows it to be inserted into
+** the string.
+**
+** For example, assume the string variable zText contains text as follows:
+**
+** <blockquote><pre>
+** char *zText = "It's a happy day!";
+** </pre></blockquote>
+**
+** One can use this text in an SQL statement as follows:
+**
+** <blockquote><pre>
+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
+** sqlite3_exec(db, zSQL, 0, 0, 0);
+** sqlite3_free(zSQL);
+** </pre></blockquote>
+**
+** Because the %q format string is used, the '\'' character in zText
+** is escaped and the SQL generated is as follows:
+**
+** <blockquote><pre>
+** INSERT INTO table1 VALUES('It''s a happy day!')
+** </pre></blockquote>
+**
+** This is correct. Had we used %s instead of %q, the generated SQL
+** would have looked like this:
+**
+** <blockquote><pre>
+** INSERT INTO table1 VALUES('It's a happy day!');
+** </pre></blockquote>
+**
+** This second example is an SQL syntax error. As a general rule you should
+** always use %q instead of %s when inserting text into a string literal.
+**
+** ^(The %Q option works like %q except it also adds single quotes around
+** the outside of the total string. Additionally, if the parameter in the
+** argument list is a NULL pointer, %Q substitutes the text "NULL" (without
+** single quotes).)^ So, for example, one could say:
+**
+** <blockquote><pre>
+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText);
+** sqlite3_exec(db, zSQL, 0, 0, 0);
+** sqlite3_free(zSQL);
+** </pre></blockquote>
+**
+** The code above will render a correct SQL statement in the zSQL
+** variable even if the zText variable is a NULL pointer.
+**
+** ^(The "%z" formatting option works like "%s" but with the
+** addition that after the string has been read and copied into
+** the result, [sqlite3_free()] is called on the input string.)^

+** CAPI3REF: Compile-Time Authorization Callbacks

+** ^The authorizer callback is invoked as SQL statements are being compiled
+** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
+** [sqlite3_prepare16()] and [sqlite3_prepare16_v2()]. ^At various
+** points during the compilation process, as logic is being created
+** to perform various actions, the authorizer callback is invoked to
+** see if those actions are allowed. ^The authorizer callback should
+** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
+** specific action but allow the SQL statement to continue to be
+** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
+** rejected with an error. ^If the authorizer callback returns
+** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
+** then the [sqlite3_prepare_v2()] or equivalent call that triggered
+** the authorizer will fail with an error message.
+**
+** When the callback returns [SQLITE_OK], that means the operation
+** requested is ok. ^When the callback returns [SQLITE_DENY], the
+** [sqlite3_prepare_v2()] or equivalent call that triggered the
+** authorizer will fail with an error message explaining that
+** access is denied.
+**
+** ^The first parameter to the authorizer callback is a copy of the third
+** parameter to the sqlite3_set_authorizer() interface. ^The second parameter
+** to the callback is an integer [SQLITE_COPY | action code] that specifies
+** the particular action to be authorized. ^The third through sixth parameters
+** to the callback are zero-terminated strings that contain additional
+** details about the action to be authorized.
+**
+** ^If the action code is [SQLITE_READ]
+** and the callback returns [SQLITE_IGNORE] then the
+** [prepared statement] statement is constructed to substitute
+** a NULL value in place of the table column that would have
+** been read if [SQLITE_OK] had been returned. The [SQLITE_IGNORE]
+** return can be used to deny an untrusted user access to individual
+** columns of a table.
+** ^If the action code is [SQLITE_DELETE] and the callback returns
+** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
+** [truncate optimization] is disabled and all rows are deleted individually.
+**
+** An authorizer is used when [sqlite3_prepare | preparing]
+** SQL statements from an untrusted source, to ensure that the SQL statements
+** do not try to access data they are not allowed to see, or that they do not
+** try to execute malicious statements that damage the database. For
+** example, an application may allow a user to enter arbitrary
+** SQL queries for evaluation by a database. But the application does
+** not want the user to be able to make arbitrary changes to the
+** database. An authorizer could then be put in place while the
+** user-entered SQL is being [sqlite3_prepare | prepared] that
+** disallows everything except [SELECT] statements.
+**
+** Applications that need to process SQL from untrusted sources
+** might also consider lowering resource limits using [sqlite3_limit()]
+** and limiting database size using the [max_page_count] [PRAGMA]
+** in addition to using an authorizer.
+**
+** ^(Only a single authorizer can be in place on a database connection
+** at a time. Each call to sqlite3_set_authorizer overrides the
+** previous call.)^ ^Disable the authorizer by installing a NULL callback.
+** The authorizer is disabled by default.
+**
+** The authorizer callback must not do anything that will modify
+** the database connection that invoked the authorizer callback.
+** Note that [sqlite3_prepare_v2()] and [sqlite3_step()] both modify their
+** database connections for the meaning of "modify" in this paragraph.
+**
+** ^When [sqlite3_prepare_v2()] is used to prepare a statement, the
+** statement might be re-prepared during [sqlite3_step()] due to a
+** schema change. Hence, the application should ensure that the
+** correct authorizer callback remains in place during the [sqlite3_step()].
+**
+** ^Note that the authorizer callback is invoked only during
+** [sqlite3_prepare()] or its variants. Authorization is not
+** performed during statement evaluation in [sqlite3_step()], unless

+** [[URI filenames in sqlite3_open()]] <h3>URI Filenames</h3>
+**
+** ^If [URI filename] interpretation is enabled, and the filename argument

+** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
+** set in the fourth argument to sqlite3_open_v2(), or if it has
+** been enabled globally using the [SQLITE_CONFIG_URI] option with the
+** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
+** As of SQLite version 3.7.7, URI filename interpretation is turned off
+** by default, but future releases of SQLite might enable URI filename
+** interpretation by default. See "[URI filenames]" for additional
+** information.
+**
+** URI filenames are parsed according to RFC 3986. ^If the URI contains an
+** authority, then it must be either an empty string or the string
+** "localhost". ^If the authority is not an empty string or "localhost", an
+** error is returned to the caller. ^The fragment component of a URI, if
+** present, is ignored.
+**
+** ^SQLite uses the path component of the URI as the name of the disk file
+** which contains the database. ^If the path begins with a '/' character,
+** then it is interpreted as an absolute path. ^If the path does not begin
+** with a '/' (meaning that the authority section is omitted from the URI)
+** then the path is interpreted as a relative path.
+** ^On windows, the first component of an absolute path
+** is a drive specification (e.g. "C:").
+**
+** [[core URI query parameters]]
+** The query component of a URI may contain parameters that are interpreted
+** either by SQLite itself, or by a [VFS | custom VFS implementation].
+** SQLite interprets the following three query parameters:
+**
+** <ul>
+** <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
+** a VFS object that provides the operating system interface that should
+** be used to access the database file on disk. ^If this option is set to
+** an empty string the default VFS object is used. ^Specifying an unknown
+** VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
+** present, then the VFS specified by the option takes precedence over
+** the value passed as the fourth parameter to sqlite3_open_v2().
+**
+** <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw",
+** "rwc", or "memory". Attempting to set it to any other value is
+** an error)^.
+** ^If "ro" is specified, then the database is opened for read-only
+** access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the
+** third argument to sqlite3_open_v2(). ^If the mode option is set to
+** "rw", then the database is opened for read-write (but not create)
+** access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had
+** been set. ^Value "rwc" is equivalent to setting both
+** SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE. ^If the mode option is
+** set to "memory" then a pure [in-memory database] that never reads
+** or writes from disk is used. ^It is an error to specify a value for
+** the mode parameter that is less restrictive than that specified by
+** the flags passed in the third parameter to sqlite3_open_v2().
+**
+** <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
+** "private". ^Setting it to "shared" is equivalent to setting the
+** SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
+** sqlite3_open_v2(). ^Setting the cache parameter to "private" is
+** equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
+** ^If sqlite3_open_v2() is used and the "cache" parameter is present in
+** a URI filename, its value overrides any behavior requested by setting
+** SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
+** </ul>
+**
+** ^Specifying an unknown parameter in the query component of a URI is not an
+** error. Future versions of SQLite might understand additional query
+** parameters. See "[query parameters with special meaning to SQLite]" for
+** additional information.

+** CAPI3REF: Compiling An SQL Statement
+** KEYWORDS: {SQL statement compiler}
+**
+** To execute an SQL query, it must first be compiled into a byte-code
+** program using one of these routines.
+**
+** The first argument, "db", is a [database connection] obtained from a
+** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
+** [sqlite3_open16()]. The database connection must not have been closed.
+**
+** The second argument, "zSql", is the statement to be compiled, encoded
+** as either UTF-8 or UTF-16. The sqlite3_prepare() and sqlite3_prepare_v2()
+** interfaces use UTF-8, and sqlite3_prepare16() and sqlite3_prepare16_v2()
+** use UTF-16.
+**
+** ^If the nByte argument is less than zero, then zSql is read up to the
+** first zero terminator. ^If nByte is non-negative, then it is the maximum
+** number of bytes read from zSql. ^When nByte is non-negative, the
+** zSql string ends at either the first '\000' or '\u0000' character or
+** the nByte-th byte, whichever comes first. If the caller knows
+** that the supplied string is nul-terminated, then there is a small
+** performance advantage to be gained by passing an nByte parameter that
+** is equal to the number of bytes in the input string <i>including</i>
+** the nul-terminator bytes as this saves SQLite from having to
+** make a copy of the input string.
+**
+** ^If pzTail is not NULL then *pzTail is made to point to the first byte
+** past the end of the first SQL statement in zSql. These routines only
+** compile the first statement in zSql, so *pzTail is left pointing to
+** what remains uncompiled.
+**
+** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
+** executed using [sqlite3_step()]. ^If there is an error, *ppStmt is set
+** to NULL. ^If the input text contains no SQL (if the input is an empty
+** string or a comment) then *ppStmt is set to NULL.
+** The calling procedure is responsible for deleting the compiled
+** SQL statement using [sqlite3_finalize()] after it has finished with it.
+** ppStmt may not be NULL.
+**
+** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
+** otherwise an [error code] is returned.
+**
+** The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are
+** recommended for all new programs. The two older interfaces are retained
+** for backwards compatibility, but their use is discouraged.
+** ^In the "v2" interfaces, the prepared statement
+** that is returned (the [sqlite3_stmt] object) contains a copy of the
+** original SQL text. This causes the [sqlite3_step()] interface to
+** behave differently in three ways:
+**
+** <ol>
+** <li>
+** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
+** always used to do, [sqlite3_step()] will automatically recompile the SQL
+** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
+** retries will occur before sqlite3_step() gives up and returns an error.
+** </li>
+**
+** <li>
+** ^When an error occurs, [sqlite3_step()] will return one of the detailed
+** [error codes] or [extended error codes]. ^The legacy behavior was that
+** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
+** and the application would have to make a second call to [sqlite3_reset()]
+** in order to find the underlying cause of the problem. With the "v2" prepare
+** interfaces, the underlying reason for the error is returned immediately.
+** </li>
+**
+** <li>
+** ^If the specific value bound to [parameter | host parameter] in the
+** WHERE clause might influence the choice of query plan for a statement,
+** then the statement will be automatically recompiled, as if there had been
+** a schema change, on the first [sqlite3_step()] call following any change
+** to the [sqlite3_bind_text | bindings] of that [parameter].
+** ^The specific value of WHERE-clause [parameter] might influence the
+** choice of query plan if the parameter is the left-hand side of a [LIKE]

+** and the [SQLITE_ENABLE_STAT3] compile-time option is enabled.

+** must be called one or more times to evaluate the statement.
+**
+** The details of the behavior of the sqlite3_step() interface depend
+** on whether the statement was prepared using the newer "v2" interface
+** [sqlite3_prepare_v2()] and [sqlite3_prepare16_v2()] or the older legacy
+** interface [sqlite3_prepare()] and [sqlite3_prepare16()]. The use of the
+** new "v2" interface is recommended for new applications but the legacy
+** interface will continue to be supported.
+**
+** ^In the legacy interface, the return value will be either [SQLITE_BUSY],
+** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
+** ^With the "v2" interface, any of the other [result codes] or
+** [extended result codes] might be returned as well.
+**
+** ^[SQLITE_BUSY] means that the database engine was unable to acquire the
+** database locks it needs to do its job. ^If the statement is a [COMMIT]
+** or occurs outside of an explicit transaction, then you can retry the
+** statement. If the statement is not a [COMMIT] and occurs within an
+** explicit transaction then you should rollback the transaction before
+** continuing.
+**
+** ^[SQLITE_DONE] means that the statement has finished executing
+** successfully. sqlite3_step() should not be called again on this virtual
+** machine without first calling [sqlite3_reset()] to reset the virtual
+** machine back to its initial state.
+**
+** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
+** is returned each time a new row of data is ready for processing by the
+** caller. The values may be accessed using the [column access functions].
+** sqlite3_step() is called again to retrieve the next row of data.
+**
+** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
+** violation) has occurred. sqlite3_step() should not be called again on
+** the VM. More information may be found by calling [sqlite3_errmsg()].
+** ^With the legacy interface, a more specific error code (for example,
+** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
+** can be obtained by calling [sqlite3_reset()] on the
+** [prepared statement]. ^In the "v2" interface,
+** the more specific error code is returned directly by sqlite3_step().
+**
+** [SQLITE_MISUSE] means that the this routine was called inappropriately.
+** Perhaps it was called on a [prepared statement] that has
+** already been [sqlite3_finalize | finalized] or on one that had
+** previously returned [SQLITE_ERROR] or [SQLITE_DONE]. Or it could
+** be the case that the same database connection is being used by two or
+** more threads at the same moment in time.
+**
+** For all versions of SQLite up to and including 3.6.23.1, a call to
+** [sqlite3_reset()] was required after sqlite3_step() returned anything
+** other than [SQLITE_ROW] before any subsequent invocation of
+** sqlite3_step(). Failure to reset the prepared statement using
+** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
+** sqlite3_step(). But after version 3.6.23.1, sqlite3_step() began
+** calling [sqlite3_reset()] automatically in this circumstance rather
+** than returning [SQLITE_MISUSE]. This is not considered a compatibility
+** break because any application that ever receives an SQLITE_MISUSE error
+** is broken by definition. The [SQLITE_OMIT_AUTORESET] compile-time option
+** can be used to restore the legacy behavior.
+**
+** <b>Goofy Interface Alert:</b> In the legacy interface, the sqlite3_step()
+** API always returns a generic error code, [SQLITE_ERROR], following any
+** error other than [SQLITE_BUSY] and [SQLITE_MISUSE]. You must call
+** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
+** specific [error codes] that better describes the error.
+** We admit that this is a goofy design. The problem has been fixed
+** with the "v2" interface. If you prepare all of your SQL statements
+** using either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] instead
+** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()] interfaces,

+**
+** Note that when type conversions occur, pointers returned by prior
+** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or

+** to UTF-16.</li>
+** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
+** sqlite3_column_text() is called. The content must be converted
+** to UTF-8.</li>
+** </ul>
+**
+** ^Conversions between UTF-16be and UTF-16le are always done in place and do
+** not invalidate a prior pointer, though of course the content of the buffer
+** that the prior pointer references will have been modified. Other kinds
+** of conversion are done in place when it is possible, but sometimes they
+** are not possible and in those cases prior pointers are invalidated.
+**
+** The safest and easiest to remember policy is to invoke these routines
+** in one of the following ways:
+**
+** <ul>
+** <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
+** <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
+** <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
+** </ul>
+**
+** In other words, you should call sqlite3_column_text(),
+** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
+** into the desired format, then invoke sqlite3_column_bytes() or

+**
+** ^The sixth, seventh and eighth parameters, xFunc, xStep and xFinal, are

+**
+** ^(If the ninth parameter to sqlite3_create_function_v2() is not NULL,

+** to [sqlite3_create_function()] and [sqlite3_create_function16()]
+** define callbacks that implement the SQL functions and aggregates.
+** The 3rd parameter to these callbacks is an array of pointers to

+**
+** ^These routines work just like the corresponding [column access functions]
+** except that these routines take a single [protected sqlite3_value] object
+** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.

+** [SQLITE_CONFIG_MUTEX] option of the sqlite3_config() function
+** before calling sqlite3_initialize() or any other public sqlite3_
+** function that calls sqlite3_initialize().)^
+**
+** ^The sqlite3_mutex_alloc() routine allocates a new
+** mutex and returns a pointer to it. ^If it returns NULL
+** that means that a mutex could not be allocated. ^SQLite
+** will unwind its stack and return an error. ^(The argument

+**
+** <ul>

+** </ul>)^
+**
+** ^The first two constants (SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE)
+** cause sqlite3_mutex_alloc() to create
+** a new mutex. ^The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
+** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
+** The mutex implementation does not need to make a distinction
+** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
+** not want to. ^SQLite will only request a recursive mutex in
+** cases where it really needs one. ^If a faster non-recursive mutex
+** implementation is available on the host platform, the mutex subsystem
+** might return such a mutex in response to SQLITE_MUTEX_FAST.
+**
+** ^The other allowed parameters to sqlite3_mutex_alloc() (anything other
+** than SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE) each return
+** a pointer to a static preexisting mutex. ^Six static mutexes are
+** used by the current version of SQLite. Future versions of SQLite
+** may add additional static mutexes. Static mutexes are for internal
+** use by SQLite only. Applications that use SQLite mutexes should
+** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
+** SQLITE_MUTEX_RECURSIVE.
+**
+** ^Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
+** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
+** returns a different mutex on every call. ^But for the static
+** mutex types, the same mutex is returned on every call that has
+** the same type number.
+**
+** ^The sqlite3_mutex_free() routine deallocates a previously
+** allocated dynamic mutex. ^SQLite is careful to deallocate every
+** dynamic mutex that it allocates. The dynamic mutexes must not be in
+** use when they are deallocated. Attempting to deallocate a static
+** mutex results in undefined behavior. ^SQLite never deallocates
+** a static mutex.
+**
+** ^The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
+** to enter a mutex. ^If another thread is already within the mutex,
+** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
+** SQLITE_BUSY. ^The sqlite3_mutex_try() interface returns [SQLITE_OK]
+** upon successful entry. ^(Mutexes created using
+** SQLITE_MUTEX_RECURSIVE can be entered multiple times by the same thread.
+** In such cases the,
+** mutex must be exited an equal number of times before another thread
+** can enter.)^ ^(If the same thread tries to enter any other
+** kind of mutex more than once, the behavior is undefined.
+** SQLite will never exhibit
+** such behavior in its own use of mutexes.)^
+**
+** ^(Some systems (for example, Windows 95) do not support the operation
+** implemented by sqlite3_mutex_try(). On those systems, sqlite3_mutex_try()
+** will always return SQLITE_BUSY. The SQLite core only ever uses
+** sqlite3_mutex_try() as an optimization so this is acceptable behavior.)^
+**
+** ^The sqlite3_mutex_leave() routine exits a mutex that was
+** previously entered by the same thread. ^(The behavior
+** is undefined if the mutex is not currently entered by the
+** calling thread or is not currently allocated. SQLite will

+**
+** Usually, the default mutex implementations provided by SQLite are
+** sufficient, however the user has the option of substituting a custom
+** implementation for specialized deployments or systems for which SQLite
+** does not provide a suitable implementation. In this case, the user
+** creates and populates an instance of this structure to pass
+** to sqlite3_config() along with the [SQLITE_CONFIG_MUTEX] option.
+** Additionally, an instance of this structure can be used as an
+** output variable when querying the system for the current mutex
+** implementation, using the [SQLITE_CONFIG_GETMUTEX] option.
+**
+** ^The xMutexInit method defined by this structure is invoked as
+** part of system initialization by the sqlite3_initialize() function.
+** ^The xMutexInit routine is called by SQLite exactly once for each
+** effective call to [sqlite3_initialize()].
+**
+** ^The xMutexEnd method defined by this structure is invoked as
+** part of system shutdown by the sqlite3_shutdown() function. The
+** implementation of this method is expected to release all outstanding
+** resources obtained by the mutex methods implementation, especially
+** those obtained by the xMutexInit method. ^The xMutexEnd()
+** interface is invoked exactly once for each call to [sqlite3_shutdown()].
+**
+** ^(The remaining seven methods defined by this structure (xMutexAlloc,
+** xMutexFree, xMutexEnter, xMutexTry, xMutexLeave, xMutexHeld and
+** xMutexNotheld) implement the following interfaces (respectively):
+**
+** <ul>

+**
+** The only difference is that the public sqlite3_XXX functions enumerated

+** of a valid mutex handle. The implementations of the methods defined
+** by this structure are not required to handle this case, the results
+** of passing a NULL pointer instead of a valid mutex handle are undefined
+** (i.e. it is acceptable to provide an implementation that segfaults if
+** it is passed a NULL pointer).
+**
+** The xMutexInit() method must be threadsafe. ^It must be harmless to

+** allocation for a static mutex. ^However xMutexAlloc() may use SQLite
+** memory allocation for a fast or recursive mutex.
+**
+** ^SQLite will invoke the xMutexEnd() method when [sqlite3_shutdown()] is

+**
+** ^(The [sqlite3_config]([SQLITE_CONFIG_PCACHE2], ...) interface can
+** register an alternative page cache implementation by passing in an
+** instance of the sqlite3_pcache_methods2 structure.)^
+** In many applications, most of the heap memory allocated by
+** SQLite is used for the page cache.
+** By implementing a
+** custom page cache using this API, an application can better control
+** the amount of memory consumed by SQLite, the way in which
+** that memory is allocated and released, and the policies used to
+** determine exactly which parts of a database file are cached and for
+** how long.
+**
+** The alternative page cache mechanism is an
+** extreme measure that is only needed by the most demanding applications.
+** The built-in page cache is recommended for most uses.
+**
+** ^(The contents of the sqlite3_pcache_methods2 structure are copied to an
+** internal buffer by SQLite within the call to [sqlite3_config]. Hence
+** the application may discard the parameter after the call to
+** [sqlite3_config()] returns.)^
+**
+** [[the xInit() page cache method]]
+** ^(The xInit() method is called once for each effective
+** call to [sqlite3_initialize()])^
+** (usually only once during the lifetime of the process). ^(The xInit()
+** method is passed a copy of the sqlite3_pcache_methods2.pArg value.)^
+** The intent of the xInit() method is to set up global data structures
+** required by the custom page cache implementation.
+** ^(If the xInit() method is NULL, then the
+** built-in default page cache is used instead of the application defined
+** page cache.)^
+**
+** [[the xShutdown() page cache method]]
+** ^The xShutdown() method is called by [sqlite3_shutdown()].
+** It can be used to clean up
+** any outstanding resources before process shutdown, if required.
+** ^The xShutdown() method may be NULL.
+**
+** ^SQLite automatically serializes calls to the xInit method,
+** so the xInit method need not be threadsafe. ^The
+** xShutdown method is only called from [sqlite3_shutdown()] so it does
+** not need to be threadsafe either. All other methods must be threadsafe
+** in multithreaded applications.
+**
+** ^SQLite will never invoke xInit() more than once without an intervening
+** call to xShutdown().
+**
+** [[the xCreate() page cache methods]]
+** ^SQLite invokes the xCreate() method to construct a new cache instance.
+** SQLite will typically create one cache instance for each open database file,
+** though this is not guaranteed. ^The
+** first parameter, szPage, is the size in bytes of the pages that must
+** be allocated by the cache. ^szPage will always a power of two. ^The
+** second parameter szExtra is a number of bytes of extra storage
+** associated with each page cache entry. ^The szExtra parameter will
+** a number less than 250. SQLite will use the
+** extra szExtra bytes on each page to store metadata about the underlying
+** database page on disk. The value passed into szExtra depends
+** on the SQLite version, the target platform, and how SQLite was compiled.
+** ^The third argument to xCreate(), bPurgeable, is true if the cache being
+** created will be used to cache database pages of a file stored on disk, or
+** false if it is used for an in-memory database. The cache implementation
+** does not have to do anything special based with the value of bPurgeable;
+** it is purely advisory. ^On a cache where bPurgeable is false, SQLite will
+** never invoke xUnpin() except to deliberately delete a page.
+** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
+** false will always have the "discard" flag set to true.
+** ^Hence, a cache created with bPurgeable false will
+** never contain any unpinned pages.
+**
+** [[the xCachesize() page cache method]]
+** ^(The xCachesize() method may be called at any time by SQLite to set the
+** suggested maximum cache-size (number of pages stored by) the cache
+** instance passed as the first argument. This is the value configured using
+** the SQLite "[PRAGMA cache_size]" command.)^ As with the bPurgeable
+** parameter, the implementation is not required to do anything with this
+** value; it is advisory only.
+**
+** [[the xPagecount() page cache methods]]
+** The xPagecount() method must return the number of pages currently
+** stored in the cache, both pinned and unpinned.
+**
+** [[the xFetch() page cache methods]]
+** The xFetch() method locates a page in the cache and returns a pointer to
+** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
+** The pBuf element of the returned sqlite3_pcache_page object will be a
+** pointer to a buffer of szPage bytes used to store the content of a
+** single database page. The pExtra element of sqlite3_pcache_page will be
+** a pointer to the szExtra bytes of extra storage that SQLite has requested
+** for each entry in the page cache.
+**
+** The page to be fetched is determined by the key. ^The minimum key value
+** is 1. After it has been retrieved using xFetch, the page is considered
+** to be "pinned".
+**
+** If the requested page is already in the page cache, then the page cache
+** implementation must return a pointer to the page buffer with its content
+** intact. If the requested page is not already in the cache, then the
+** cache implementation should use the value of the createFlag
+** parameter to help it determined what action to take:
+**
+** <table border=1 width=85% align=center>
+** <tr><th> createFlag <th> Behavior when page is not already in cache
+** <tr><td> 0 <td> Do not allocate a new page. Return NULL.
+** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
+** Otherwise return NULL.
+** <tr><td> 2 <td> Make every effort to allocate a new page. Only return
+** NULL if allocating a new page is effectively impossible.
+** </table>
+**
+** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1. SQLite
+** will only use a createFlag of 2 after a prior call with a createFlag of 1
+** failed.)^ In between the to xFetch() calls, SQLite may
+** attempt to unpin one or more cache pages by spilling the content of
+** pinned pages to disk and synching the operating system disk cache.
+**
+** [[the xUnpin() page cache method]]
+** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
+** as its second argument. If the third parameter, discard, is non-zero,
+** then the page must be evicted from the cache.
+** ^If the discard parameter is
+** zero, then the page may be discarded or retained at the discretion of
+** page cache implementation. ^The page cache implementation
+** may choose to evict unpinned pages at any time.
+**
+** The cache must not perform any reference counting. A single
+** call to xUnpin() unpins the page regardless of the number of prior calls
+** to xFetch().
+**
+** [[the xRekey() page cache methods]]
+** The xRekey() method is used to change the key value associated with the
+** page passed as the second argument. If the cache
+** previously contains an entry associated with newKey, it must be
+** discarded. ^Any prior cache entry associated with newKey is guaranteed not
+** to be pinned.
+**
+** When SQLite calls the xTruncate() method, the cache must discard all
+** existing cache entries with page numbers (keys) greater than or equal
+** to the value of the iLimit parameter passed to xTruncate(). If any
+** of these pages are pinned, they are implicitly unpinned, meaning that
+** they can be safely discarded.
+**
+** [[the xDestroy() page cache method]]
+** ^The xDestroy() method is used to delete a cache allocated by xCreate().
+** All resources associated with the specified cache should be freed. ^After
+** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
+** handle invalid, and will not use it with any other sqlite3_pcache_methods2
+** functions.
+**
+** [[the xShrink() page cache method]]
+** ^SQLite invokes the xShrink() method when it wants the page cache to
+** free up as much of heap memory as possible. The page cache implementation
+** is not obligated to free any memory, but well-behaved implementations should
+** do their best.

+** and the second is the number of entries in the array.
+**
+** When a blocking connections transaction is concluded, there may be
+** more than one blocked connection that has registered for an unlock-notify
+** callback. ^If two or more such blocked connections have specified the
+** same callback function, then instead of invoking the callback function
+** multiple times, it is invoked once with the set of void* context pointers
+** specified by the blocked connections bundled together into an array.
+** This gives the application an opportunity to prioritize any actions
+** related to the set of unblocked database connections.
+**
+** <b>Deadlock Detection</b>
+**
+** Assuming that after registering for an unlock-notify callback a
+** database waits for the callback to be issued before taking any further
+** action (a reasonable assumption), then using this API may cause the
+** application to deadlock. For example, if connection X is waiting for
+** connection Y's transaction to be concluded, and similarly connection
+** Y is waiting on connection X's transaction, then neither connection
+** will proceed and the system may remain deadlocked indefinitely.
+**
+** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
+** detection. ^If a given call to sqlite3_unlock_notify() would put the
+** system in a deadlocked state, then SQLITE_LOCKED is returned and no
+** unlock-notify callback is registered. The system is said to be in
+** a deadlocked state if connection A has registered for an unlock-notify
+** callback on the conclusion of connection B's transaction, and connection
+** B has itself registered for an unlock-notify callback when connection
+** A's transaction is concluded. ^Indirect deadlock is also detected, so
+** the system is also considered to be deadlocked if connection B has
+** registered for an unlock-notify callback on the conclusion of connection
+** C's transaction, where connection C is waiting on connection A. ^Any
+** number of levels of indirection are allowed.
+**
+** <b>The "DROP TABLE" Exception</b>
+**
+** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost
+** always appropriate to call sqlite3_unlock_notify(). There is however,
+** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
+** SQLite checks if there are any currently executing SELECT statements
+** that belong to the same connection. If there are, SQLITE_LOCKED is
+** returned. In this case there is no "blocking connection", so invoking
+** sqlite3_unlock_notify() results in the unlock-notify callback being
+** invoked immediately. If the application then re-attempts the "DROP TABLE"
+** or "DROP INDEX" query, an infinite loop might be the result.
+**
+** One way around this problem is to check the extended error code returned
+** by an sqlite3_step() call. ^(If there is a blocking connection, then the
+** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
+** the special "DROP TABLE/INDEX" case, the extended error code is just
+** SQLITE_LOCKED.)^

+**
+** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
+** those functions are not available. So we use only LockFile() and
+** UnlockFile().
+**
+** LockFile() prevents not just writing but also reading by other processes.
+** A SHARED_LOCK is obtained by locking a single randomly-chosen
+** byte out of a specific range of bytes. The lock byte is obtained at
+** random so two separate readers can probably access the file at the
+** same time, unless they are unlucky and choose the same lock byte.
+** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range.
+** There can only be one writer. A RESERVED_LOCK is obtained by locking
+** a single byte of the file that is designated as the reserved lock byte.
+** A PENDING_LOCK is obtained by locking a designated byte different from
+** the RESERVED_LOCK byte.
+**
+** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
+** which means we can use reader/writer locks. When reader/writer locks
+** are used, the lock is placed on the same range of bytes that is used
+** for probabilistic locking in Win95/98/ME. Hence, the locking scheme
+** will support two or more Win95 readers or two or more WinNT readers.
+** But a single Win95 reader will lock out all WinNT readers and a single
+** WinNT reader will lock out all other Win95 readers.
+**
+** The following #defines specify the range of bytes used for locking.
+** SHARED_SIZE is the number of bytes available in the pool from which
+** a random byte is selected for a shared lock. The pool of bytes for
+** shared locks begins at SHARED_FIRST.
+**
+** The same locking strategy and
+** byte ranges are used for Unix. This leaves open the possiblity of having
+** clients on win95, winNT, and unix all talking to the same shared file
+** and all locking correctly. To do so would require that samba (or whatever
+** tool is being used for file sharing) implements locks correctly between
+** windows and unix. I'm guessing that isn't likely to happen, but by
+** using the same locking range we are at least open to the possibility.
+**
+** Locking in windows is manditory. For this reason, we cannot store
+** actual data in the bytes used for locking. The pager never allocates
+** the pages involved in locking therefore. SHARED_SIZE is selected so
+** that all locks will fit on a single page even at the minimum page size.
+** PENDING_BYTE defines the beginning of the locks. By default PENDING_BYTE
+** is set high so that we don't have to allocate an unused page except
+** for very large databases. But one should test the page skipping logic
+** by setting PENDING_BYTE low and running the entire regression suite.
+**
+** Changing the value of PENDING_BYTE results in a subtly incompatible
+** file format. Depending on how it is changed, you might not notice
+** the incompatibility right away, even running a full regression test.
+** The default location of PENDING_BYTE is the first byte past the

+** If the database schema is shared, then there is one instance of this
+** structure for each database connection (sqlite3*) that uses the shared
+** schema. This is because each database connection requires its own unique
+** instance of the sqlite3_vtab* handle used to access the virtual table
+** implementation. sqlite3_vtab* handles can not be shared between
+** database connections, even when the rest of the in-memory database
+** schema is shared, as the implementation often stores the database
+** connection handle passed to it via the xConnect() or xCreate() method
+** during initialization internally. This database connection handle may
+** then be used by the virtual table implementation to access real tables
+** within the database. So that they appear as part of the callers
+** transaction, these accesses need to be made via the same database
+** connection as that used to execute SQL operations on the virtual table.
+**
+** All VTable objects that correspond to a single table in a shared
+** database schema are initially stored in a linked-list pointed to by
+** the Table.pVTable member variable of the corresponding Table object.
+** When an sqlite3_prepare() operation is required to access the virtual
+** table, it searches the list for the VTable that corresponds to the
+** database connection doing the preparing so as to use the correct
+** sqlite3_vtab* handle in the compiled query.
+**
+** When an in-memory Table object is deleted (for example when the
+** schema is being reloaded for some reason), the VTable objects are not
+** deleted and the sqlite3_vtab* handles are not xDisconnect()ed
+** immediately. Instead, they are moved from the Table.pVTable list to
+** another linked list headed by the sqlite3.pDisconnect member of the
+** corresponding sqlite3 structure. They are then deleted/xDisconnected
+** next time a statement is prepared using said sqlite3*. This is done
+** to avoid deadlock issues involving multiple sqlite3.mutex mutexes.
+** Refer to comments above function sqlite3VtabUnlockList() for an
+** explanation as to why it is safe to add an entry to an sqlite3.pDisconnect
+** list without holding the corresponding sqlite3.mutex mutex.

+** 1970-01-01 00:00:00 is JD 2440587.5
+** 2000-01-01 00:00:00 is JD 2451544.5
+**
+** This implemention requires years to be expressed as a 4-digit number
+** which means that only dates between 0000-01-01 and 9999-12-31 can
+** be represented, even though julian day numbers allow a much wider
+** range of dates.
+**
+** The Gregorian calendar system is used for all dates and times,
+** even those that predate the Gregorian calendar. Historians usually
+** use the Julian calendar for dates prior to 1582-10-15 and for some
+** dates afterwards, depending on locale. Beware of this difference.
+**
+** The conversion algorithms are implemented based on descriptions

+** This file contains the C functions that implement a memory

+**
+** This version of the memory allocation subsystem omits all

+** before calling sqlite3_initialize() from which allocations
+** are made and returned by the xMalloc() and xRealloc()
+** implementations. Once sqlite3_initialize() has been called,
+** the amount of memory available to SQLite is fixed and cannot
+** be changed.
+**
+** This version of the memory allocation subsystem is included
+** in the build only if SQLITE_ENABLE_MEMSYS3 is defined.

+** This version of the memory allocator is only built into the library
+** SQLITE_ENABLE_MEMSYS3 is defined. Defining this symbol does not

+** it is available. The mempool allocator is activated by calling
+** sqlite3_config().

+** A memory allocation (also called a "chunk") consists of two or
+** more blocks where each block is 8 bytes. The first 8 bytes are
+** a header that is not returned to the user.
+**
+** A chunk is two or more blocks that is either checked out or
+** free. The first block has format u.hdr. u.hdr.size4x is 4 times the
+** size of the allocation in blocks if the allocation is free.
+** The u.hdr.size4x&1 bit is true if the chunk is checked out and
+** false if the chunk is on the freelist. The u.hdr.size4x&2 bit
+** is true if the previous chunk is checked out and false if the
+** previous chunk is free. The u.hdr.prevSize field is the size of
+** the previous chunk in blocks if the previous chunk is on the
+** freelist. If the previous chunk is checked out, then
+** u.hdr.prevSize can be part of the data for that chunk and should
+** not be read or written.
+**
+** We often identify a chunk by its index in mem3.aPool[]. When
+** this is done, the chunk index refers to the second block of
+** the chunk. In this way, the first chunk has an index of 1.
+** A chunk index of 0 means "no such chunk" and is the equivalent
+** of a NULL pointer.
+**
+** The second block of free chunks is of the form u.list. The
+** two fields form a double-linked list of chunks of related sizes.
+** Pointers to the head of the list are stored in mem3.aiSmall[]
+** for smaller chunks and mem3.aiHash[] for larger chunks.
+**
+** The second block of a chunk is user data if the chunk is checked
+** out. If a chunk is checked out, the user data may extend into
+** the u.hdr.prevSize value of the following chunk.

+** This file contains the C functions that implement a memory
+** allocation subsystem for use by SQLite.
+**
+** This version of the memory allocation subsystem omits all
+** use of malloc(). The application gives SQLite a block of memory
+** before calling sqlite3_initialize() from which allocations
+** are made and returned by the xMalloc() and xRealloc()
+** implementations. Once sqlite3_initialize() has been called,
+** the amount of memory available to SQLite is fixed and cannot
+** be changed.
+**
+** This version of the memory allocation subsystem is included
+** in the build only if SQLITE_ENABLE_MEMSYS5 is defined.
+**
+** This memory allocator uses the following algorithm:
+**
+** 1. All memory allocations sizes are rounded up to a power of 2.
+**
+** 2. If two adjacent free blocks are the halves of a larger block,
+** then the two blocks are coalesed into the single larger block.
+**
+** 3. New memory is allocated from the first available free block.
+**
+** This algorithm is described in: J. M. Robson. "Bounds for Some Functions
+** Concerning Dynamic Storage Allocation". Journal of the Association for
+** Computing Machinery, Volume 21, Number 8, July 1974, pages 491-499.
+**
+** Let n be the size of the largest allocation divided by the minimum
+** allocation size (after rounding all sizes up to a power of 2.) Let M
+** be the maximum amount of memory ever outstanding at one time. Let
+** N be the total amount of memory available for allocation. Robson
+** proved that this memory allocator will never breakdown due to
+** fragmentation as long as the following constraint holds:
+**
+** N >= M*(1 + log2(n)/2) - n + 1
+**
+** The sqlite3_status() logic tracks the maximum values of n and M so
+** that an application can, at any time, verify this constraint.

+** The sqlite3_mutex_alloc() routine allocates a new

+** will unwind its stack and return an error. The argument
+** to sqlite3_mutex_alloc() is one of these integer constants:
+**
+** <ul>
+** <li> SQLITE_MUTEX_FAST
+** <li> SQLITE_MUTEX_RECURSIVE
+** <li> SQLITE_MUTEX_STATIC_MASTER

+** <li> SQLITE_MUTEX_STATIC_LRU
+** <li> SQLITE_MUTEX_STATIC_PMEM
+** </ul>
+**
+** The first two constants cause sqlite3_mutex_alloc() to create
+** a new mutex. The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
+** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
+** The mutex implementation does not need to make a distinction
+** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
+** not want to. But SQLite will only request a recursive mutex in
+** cases where it really needs one. If a faster non-recursive mutex
+** implementation is available on the host platform, the mutex subsystem
+** might return such a mutex in response to SQLITE_MUTEX_FAST.
+**
+** The other allowed parameters to sqlite3_mutex_alloc() each return
+** a pointer to a static preexisting mutex. Six static mutexes are
+** used by the current version of SQLite. Future versions of SQLite
+** may add additional static mutexes. Static mutexes are for internal
+** use by SQLite only. Applications that use SQLite mutexes should
+** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
+** SQLITE_MUTEX_RECURSIVE.
+**
+** Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
+** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
+** returns a different mutex on every call. But for the static

+** KEEP THE STRUCTURE OF THIS FILE INTACT. New code should be placed
+** in the correct division and should be clearly labeled.
+**
+** The layout of divisions is as follows:
+**
+** * General-purpose declarations and utility functions.
+** * Unique file ID logic used by VxWorks.
+** * Various locking primitive implementations (all except proxy locking):
+** + for Posix Advisory Locks
+** + for no-op locks
+** + for dot-file locks
+** + for flock() locking
+** + for named semaphore locks (VxWorks only)
+** + for AFP filesystem locks (MacOSX only)
+** * sqlite3_file methods not associated with locking.
+** * Definitions of sqlite3_io_methods objects for all locking
+** methods plus "finder" functions for each locking method.
+** * sqlite3_vfs method implementations.
+** * Locking primitives for the proxy uber-locking-method. (MacOSX only)

+** POSIX advisory locks are broken by design. ANSI STD 1003.1 (1996)
+** section 6.5.2.2 lines 483 through 490 specify that when a process
+** sets or clears a lock, that operation overrides any prior locks set
+** by the same process. It does not explicitly say so, but this implies
+** that it overrides locks set by the same process using a different
+** file descriptor. Consider this test case:
+**
+** int fd1 = open("./file1", O_RDWR|O_CREAT, 0644);
+** int fd2 = open("./file2", O_RDWR|O_CREAT, 0644);
+**
+** Suppose ./file1 and ./file2 are really the same file (because
+** one is a hard or symbolic link to the other) then if you set
+** an exclusive lock on fd1, then try to get an exclusive lock
+** on fd2, it works. I would have expected the second lock to
+** fail since there was already a lock on the file due to fd1.
+** But not so. Since both locks came from the same process, the
+** second overrides the first, even though they were on different
+** file descriptors opened on different file names.
+**
+** This means that we cannot use POSIX locks to synchronize file access
+** among competing threads of the same process. POSIX locks will work fine
+** to synchronize access for threads in separate processes, but not
+** threads within the same process.
+**
+** To work around the problem, SQLite has to manage file locks internally
+** on its own. Whenever a new database is opened, we have to find the
+** specific inode of the database file (the inode is determined by the
+** st_dev and st_ino fields of the stat structure that fstat() fills in)
+** and check for locks already existing on that inode. When locks are
+** created or removed, we have to look at our own internal record of the
+** locks to see if another thread has previously set a lock on that same
+** inode.
+**
+** (Aside: The use of inode numbers as unique IDs does not work on VxWorks.
+** For VxWorks, we have to use the alternative unique ID system based on
+** canonical filename and implemented in the previous division.)
+**
+** The sqlite3_file structure for POSIX is no longer just an integer file
+** descriptor. It is now a structure that holds the integer file
+** descriptor and a pointer to a structure that describes the internal
+** locks on the corresponding inode. There is one locking structure
+** per inode, so if the same inode is opened twice, both unixFile structures
+** point to the same locking structure. The locking structure keeps
+** a reference count (so we will know when to delete it) and a "cnt"
+** field that tells us its internal lock status. cnt==0 means the
+** file is unlocked. cnt==-1 means the file has an exclusive lock.
+** cnt>0 means there are cnt shared locks on the file.
+**
+** Any attempt to lock or unlock a file first checks the locking
+** structure. The fcntl() system call is only invoked to set a
+** POSIX lock if the internal lock structure transitions between
+** a locked and an unlocked state.
+**
+** But wait: there are yet more problems with POSIX advisory locks.
+**
+** If you close a file descriptor that points to a file that has locks,
+** all locks on that file that are owned by the current process are
+** released. To work around this problem, each unixInodeInfo object
+** maintains a count of the number of pending locks on tha inode.
+** When an attempt is made to close an unixFile, if there are
+** other unixFile open on the same inode that are holding locks, the call
+** to close() the file descriptor is deferred until all of the locks clear.
+** The unixInodeInfo structure keeps a list of file descriptors that need to
+** be closed and that list is walked (and cleared) when the last lock
+** clears.
+**
+** Yet another problem: LinuxThreads do not play well with posix locks.
+**
+** Many older versions of linux use the LinuxThreads library which is
+** not posix compliant. Under LinuxThreads, a lock created by thread
+** A cannot be modified or overridden by a different thread B.
+** Only thread A can modify the lock. Locking behavior is correct
+** if the appliation uses the newer Native Posix Thread Library (NPTL)
+** on linux - with NPTL a lock created by thread A can override locks
+** in thread B. But there is no way to know at compile-time which
+** threading library is being used. So there is no way to know at
+** compile-time whether or not thread A can override locks on thread B.
+** One has to do a run-time check to discover the behavior of the
+** current process.
+**
+** SQLite used to support LinuxThreads. But support for LinuxThreads
+** was dropped beginning with version 3.7.0. SQLite will still work with
+** LinuxThreads provided that (1) there is no more than one connection
+** per database file in the same process and (2) database connections
+** do not move across threads.

+/******************************************************************************
+************************** Begin Proxy Locking ********************************
+**
+** Proxy locking is a "uber-locking-method" in this sense: It uses the
+** other locking methods on secondary lock files. Proxy locking is a
+** meta-layer over top of the primitive locking implemented above. For
+** this reason, the division that implements of proxy locking is deferred
+** until late in the file (here) after all of the other I/O methods have
+** been defined - so that the primitive locking methods are available
+** as services to help with the implementation of proxy locking.
+**
+****
+**
+** The default locking schemes in SQLite use byte-range locks on the
+** database file to coordinate safe, concurrent access by multiple readers
+** and writers [http://sqlite.org/lockingv3.html]. The five file locking
+** states (UNLOCKED, PENDING, SHARED, RESERVED, EXCLUSIVE) are implemented
+** as POSIX read & write locks over fixed set of locations (via fsctl),
+** on AFP and SMB only exclusive byte-range locks are available via fsctl
+** with _IOWR('z', 23, struct ByteRangeLockPB2) to track the same 5 states.
+** To simulate a F_RDLCK on the shared range, on AFP a randomly selected
+** address in the shared range is taken for a SHARED lock, the entire
+** shared range is taken for an EXCLUSIVE lock):
+**
+** PENDING_BYTE 0x40000000
+** RESERVED_BYTE 0x40000001
+** SHARED_RANGE 0x40000002 -> 0x40000200
+**
+** This works well on the local file system, but shows a nearly 100x
+** slowdown in read performance on AFP because the AFP client disables
+** the read cache when byte-range locks are present. Enabling the read
+** cache exposes a cache coherency problem that is present on all OS X
+** supported network file systems. NFS and AFP both observe the
+** close-to-open semantics for ensuring cache coherency
+** [http://nfs.sourceforge.net/#faq_a8], which does not effectively
+** address the requirements for concurrent database access by multiple
+** readers and writers
+** [http://www.nabble.com/SQLite-on-NFS-cache-coherency-td15655701.html].
+**
+** To address the performance and cache coherency issues, proxy file locking
+** changes the way database access is controlled by limiting access to a
+** single host at a time and moving file locks off of the database file
+** and onto a proxy file on the local file system.
+**
+**
+** Using proxy locks
+** -----------------
+**
+** C APIs
+**
+** sqlite3_file_control(db, dbname, SQLITE_SET_LOCKPROXYFILE,
+** <proxy_path> | ":auto:");
+** sqlite3_file_control(db, dbname, SQLITE_GET_LOCKPROXYFILE, &<proxy_path>);
+**
+**
+** SQL pragmas
+**
+** PRAGMA [database.]lock_proxy_file=<proxy_path> | :auto:
+** PRAGMA [database.]lock_proxy_file
+**
+** Specifying ":auto:" means that if there is a conch file with a matching
+** host ID in it, the proxy path in the conch file will be used, otherwise
+** a proxy path based on the user's temp dir
+** (via confstr(_CS_DARWIN_USER_TEMP_DIR,...)) will be used and the
+** actual proxy file name is generated from the name and path of the
+** database file. For example:
+**
+** For database path "/Users/me/foo.db"
+** The lock path will be "<tmpdir>/sqliteplocks/_Users_me_foo.db:auto:")
+**
+** Once a lock proxy is configured for a database connection, it can not
+** be removed, however it may be switched to a different proxy path via
+** the above APIs (assuming the conch file is not being held by another
+** connection or process).
+**
+**
+** How proxy locking works
+** -----------------------
+**
+** Proxy file locking relies primarily on two new supporting files:
+**
+** * conch file to limit access to the database file to a single host
+** at a time
+**
+** * proxy file to act as a proxy for the advisory locks normally
+** taken on the database
+**
+** The conch file - to use a proxy file, sqlite must first "hold the conch"
+** by taking an sqlite-style shared lock on the conch file, reading the
+** contents and comparing the host's unique host ID (see below) and lock
+** proxy path against the values stored in the conch. The conch file is
+** stored in the same directory as the database file and the file name
+** is patterned after the database file name as ".<databasename>-conch".
+** If the conch file does not exist, or it's contents do not match the
+** host ID and/or proxy path, then the lock is escalated to an exclusive
+** lock and the conch file contents is updated with the host ID and proxy
+** path and the lock is downgraded to a shared lock again. If the conch
+** is held by another process (with a shared lock), the exclusive lock
+** will fail and SQLITE_BUSY is returned.
+**
+** The proxy file - a single-byte file used for all advisory file locks
+** normally taken on the database file. This allows for safe sharing
+** of the database file for multiple readers and writers on the same
+** host (the conch ensures that they all use the same local lock file).
+**
+** Requesting the lock proxy does not immediately take the conch, it is
+** only taken when the first request to lock database file is made.
+** This matches the semantics of the traditional locking behavior, where
+** opening a connection to a database file does not take a lock on it.
+** The shared lock and an open file descriptor are maintained until
+** the connection to the database is closed.
+**
+** The proxy file and the lock file are never deleted so they only need
+** to be created the first time they are used.
+**
+** Configuration options
+** ---------------------
+**
+** SQLITE_PREFER_PROXY_LOCKING
+**
+** Database files accessed on non-local file systems are
+** automatically configured for proxy locking, lock files are
+** named automatically using the same logic as
+** PRAGMA lock_proxy_file=":auto:"
+**
+** SQLITE_PROXY_DEBUG
+**
+** Enables the logging of error messages during host id file
+** retrieval and creation
+**
+** LOCKPROXYDIR
+**
+** Overrides the default directory used for lock proxy files that
+** are named automatically via the ":auto:" setting
+**
+** SQLITE_DEFAULT_PROXYDIR_PERMISSIONS
+**
+** Permissions to use when creating a directory for storing the
+** lock proxy files, only used when LOCKPROXYDIR is not set.
+**
+**
+** As mentioned above, when compiled with SQLITE_PREFER_PROXY_LOCKING,
+** setting the environment variable SQLITE_FORCE_PROXY_LOCKING to 1 will
+** force proxy locking to be used for every database file opened, and 0
+** will force automatic proxy locking to be disabled for all database
+** files (explicity calling the SQLITE_SET_LOCKPROXYFILE pragma or
+** sqlite_file_control API is not affected by SQLITE_FORCE_PROXY_LOCKING).

+** A bitmap is used to record which pages of a database file have been

+** property. Usually only a few pages are meet either condition.
+** So the bitmap is usually sparse and has low cardinality.
+** But sometimes (for example when during a DROP of a large table) most
+** or all of the pages in a database can get journalled. In those cases,
+** the bitmap becomes dense with high cardinality. The algorithm needs
+** to handle both cases well.
+**
+** The size of the bitmap is fixed when the object is created.
+**
+** All bits are clear when the bitmap is created. Individual bits
+** may be set or cleared one at a time.
+**
+** Test operations are about 100 times more common that set operations.
+** Clear operations are exceedingly rare. There are usually between
+** 5 and 500 set operations per Bitvec object, though the number of sets can
+** sometimes grow into tens of thousands or larger. The size of the
+** Bitvec object is the number of pages in the database file at the

+*************************************************************************
+**
+** This module implements an object we call a "RowSet".
+**
+** The RowSet object is a collection of rowids. Rowids
+** are inserted into the RowSet in an arbitrary order. Inserts
+** can be intermixed with tests to see if a given rowid has been
+** previously inserted into the RowSet.
+**
+** After all inserts are finished, it is possible to extract the
+** elements of the RowSet in sorted order. Once this extraction
+** process has started, no new elements may be inserted.
+**
+** Hence, the primitive operations for a RowSet are:
+**
+** CREATE
+** INSERT
+** TEST
+** SMALLEST
+** DESTROY
+**
+** The CREATE and DESTROY primitives are the constructor and destructor,
+** obviously. The INSERT primitive adds a new element to the RowSet.
+** TEST checks to see if an element is already in the RowSet. SMALLEST
+** extracts the least value from the RowSet.
+**
+** The INSERT primitive might allocate additional memory. Memory is
+** allocated in chunks so most INSERTs do no allocation. There is an
+** upper bound on the size of allocated memory. No memory is freed
+** until DESTROY.
+**
+** The TEST primitive includes a "batch" number. The TEST primitive
+** will only see elements that were inserted before the last change
+** in the batch number. In other words, if an INSERT occurs between
+** two TESTs where the TESTs have the same batch nubmer, then the
+** value added by the INSERT will not be visible to the second TEST.
+** The initial batch number is zero, so if the very first TEST contains
+** a non-zero batch number, it will see all prior INSERTs.
+**
+** No INSERTs may occurs after a SMALLEST. An assertion will fail if
+** that is attempted.
+**
+** The cost of an INSERT is roughly constant. (Sometime new memory
+** has to be allocated on an INSERT.) The cost of a TEST with a new
+** batch number is O(NlogN) where N is the number of elements in the RowSet.
+** The cost of a TEST using the same batch number is O(logN). The cost
+** of the first SMALLEST is O(NlogN). Second and subsequent SMALLEST
+** primitives are constant time. The cost of DESTROY is O(N).
+**
+** There is an added cost of O(N) when switching between TEST and
+** SMALLEST primitives.

+/******************* NOTES ON THE DESIGN OF THE PAGER ************************
+**
+** This comment block describes invariants that hold when using a rollback
+** journal. These invariants do not apply for journal_mode=WAL,
+** journal_mode=MEMORY, or journal_mode=OFF.
+**
+** Within this comment block, a page is deemed to have been synced
+** automatically as soon as it is written when PRAGMA synchronous=OFF.
+** Otherwise, the page is not synced until the xSync method of the VFS
+** is called successfully on the file containing the page.
+**
+** Definition: A page of the database file is said to be "overwriteable" if
+** one or more of the following are true about the page:
+**
+** (a) The original content of the page as it was at the beginning of
+** the transaction has been written into the rollback journal and
+** synced.
+**
+** (b) The page was a freelist leaf page at the start of the transaction.
+**
+** (c) The page number is greater than the largest page that existed in
+** the database file at the start of the transaction.
+**
+** (1) A page of the database file is never overwritten unless one of the
+** following are true:
+**
+** (a) The page and all other pages on the same sector are overwriteable.
+**
+** (b) The atomic page write optimization is enabled, and the entire
+** transaction other than the update of the transaction sequence
+** number consists of a single page change.
+**
+** (2) The content of a page written into the rollback journal exactly matches
+** both the content in the database when the rollback journal was written
+** and the content in the database at the beginning of the current
+** transaction.
+**
+** (3) Writes to the database file are an integer multiple of the page size
+** in length and are aligned on a page boundary.
+**
+** (4) Reads from the database file are either aligned on a page boundary and
+** an integer multiple of the page size in length or are taken from the
+** first 100 bytes of the database file.
+**
+** (5) All writes to the database file are synced prior to the rollback journal
+** being deleted, truncated, or zeroed.
+**
+** (6) If a master journal file is used, then all writes to the database file
+** are synced prior to the master journal being deleted.
+**
+** Definition: Two databases (or the same database at two points it time)
+** are said to be "logically equivalent" if they give the same answer to
+** all queries. Note in particular the content of freelist leaf
+** pages can be changed arbitarily without effecting the logical equivalence
+** of the database.
+**
+** (7) At any time, if any subset, including the empty set and the total set,
+** of the unsynced changes to a rollback journal are removed and the
+** journal is rolled back, the resulting database file will be logical
+** equivalent to the database file at the beginning of the transaction.
+**
+** (8) When a transaction is rolled back, the xTruncate method of the VFS
+** is called to restore the database file to the same size it was at
+** the beginning of the transaction. (In some VFSes, the xTruncate
+** method is a no-op, but that does not change the fact the SQLite will
+** invoke it.)
+**
+** (9) Whenever the database file is modified, at least one bit in the range
+** of bytes from 24 through 39 inclusive will be changed prior to releasing
+** the EXCLUSIVE lock, thus signaling other connections on the same
+** database to flush their caches.
+**
+** (10) The pattern of bits in bytes 24 through 39 shall not repeat in less
+** than one billion transactions.
+**
+** (11) A database file is well-formed at the beginning and at the conclusion
+** of every transaction.
+**
+** (12) An EXCLUSIVE lock is held on the database file when writing to
+** the database file.
+**
+** (13) A SHARED lock is held on the database file while reading any
+** content out of the database file.

+** * No read or write transaction is active.
+** * Any lock, or no lock at all, may be held on the database file.
+** * The dbSize, dbOrigSize and dbFileSize variables may not be trusted.
+**
+** READER:
+**
+** In this state all the requirements for reading the database in
+** rollback (non-WAL) mode are met. Unless the pager is (or recently
+** was) in exclusive-locking mode, a user-level read transaction is
+** open. The database size is known in this state.
+**
+** A connection running with locking_mode=normal enters this state when
+** it opens a read-transaction on the database and returns to state
+** OPEN after the read-transaction is completed. However a connection
+** running in locking_mode=exclusive (including temp databases) remains in
+** this state even after the read-transaction is closed. The only way
+** a locking_mode=exclusive connection can transition from READER to OPEN
+** is via the ERROR state (see below).
+**
+** * A read transaction may be active (but a write-transaction cannot).
+** * A SHARED or greater lock is held on the database file.
+** * The dbSize variable may be trusted (even if a user-level read
+** transaction is not active). The dbOrigSize and dbFileSize variables
+** may not be trusted at this point.
+** * If the database is a WAL database, then the WAL connection is open.
+** * Even if a read-transaction is not open, it is guaranteed that
+** there is no hot-journal in the file-system.
+**
+** WRITER_LOCKED:
+**
+** The pager moves to this state from READER when a write-transaction
+** is first opened on the database. In WRITER_LOCKED state, all locks
+** required to start a write-transaction are held, but no actual
+** modifications to the cache or database have taken place.
+**
+** In rollback mode, a RESERVED or (if the transaction was opened with
+** BEGIN EXCLUSIVE) EXCLUSIVE lock is obtained on the database file when
+** moving to this state, but the journal file is not written to or opened
+** to in this state. If the transaction is committed or rolled back while
+** in WRITER_LOCKED state, all that is required is to unlock the database
+** file.
+**
+** IN WAL mode, WalBeginWriteTransaction() is called to lock the log file.
+** If the connection is running with locking_mode=exclusive, an attempt
+** is made to obtain an EXCLUSIVE lock on the database file.
+**
+** * A write transaction is active.
+** * If the connection is open in rollback-mode, a RESERVED or greater
+** lock is held on the database file.
+** * If the connection is open in WAL-mode, a WAL write transaction
+** is open (i.e. sqlite3WalBeginWriteTransaction() has been successfully
+** called).
+** * The dbSize, dbOrigSize and dbFileSize variables are all valid.
+** * The contents of the pager cache have not been modified.
+** * The journal file may or may not be open.
+** * Nothing (not even the first header) has been written to the journal.
+**
+** WRITER_CACHEMOD:
+**
+** A pager moves from WRITER_LOCKED state to this state when a page is
+** first modified by the upper layer. In rollback mode the journal file
+** is opened (if it is not already open) and a header written to the
+** start of it. The database file on disk has not been modified.
+**
+** * A write transaction is active.
+** * A RESERVED or greater lock is held on the database file.
+** * The journal file is open and the first header has been written
+** to it, but the header has not been synced to disk.
+** * The contents of the page cache have been modified.
+**
+** WRITER_DBMOD:
+**
+** The pager transitions from WRITER_CACHEMOD into WRITER_DBMOD state
+** when it modifies the contents of the database file. WAL connections
+** never enter this state (since they do not modify the database file,
+** just the log file).
+**
+** * A write transaction is active.
+** * An EXCLUSIVE or greater lock is held on the database file.
+** * The journal file is open and the first header has been written
+** and synced to disk.
+** * The contents of the page cache have been modified (and possibly
+** written to disk).
+**
+** WRITER_FINISHED:
+**
+** It is not possible for a WAL connection to enter this state.
+**
+** A rollback-mode pager changes to WRITER_FINISHED state from WRITER_DBMOD
+** state after the entire transaction has been successfully written into the
+** database file. In this state the transaction may be committed simply
+** by finalizing the journal file. Once in WRITER_FINISHED state, it is
+** not possible to modify the database further. At this point, the upper
+** layer must either commit or rollback the transaction.
+**
+** * A write transaction is active.
+** * An EXCLUSIVE or greater lock is held on the database file.
+** * All writing and syncing of journal and database data has finished.
+** If no error occurred, all that remains is to finalize the journal to
+** commit the transaction. If an error did occur, the caller will need
+** to rollback the transaction.
+**
+** ERROR:
+**
+** The ERROR state is entered when an IO or disk-full error (including
+** SQLITE_IOERR_NOMEM) occurs at a point in the code that makes it
+** difficult to be sure that the in-memory pager state (cache contents,
+** db size etc.) are consistent with the contents of the file-system.
+**
+** Temporary pager files may enter the ERROR state, but in-memory pagers
+** cannot.
+**
+** For example, if an IO error occurs while performing a rollback,
+** the contents of the page-cache may be left in an inconsistent state.
+** At this point it would be dangerous to change back to READER state
+** (as usually happens after a rollback). Any subsequent readers might
+** report database corruption (due to the inconsistent cache), and if
+** they upgrade to writers, they may inadvertently corrupt the database
+** file. To avoid this hazard, the pager switches into the ERROR state
+** instead of READER following such an error.
+**
+** Once it has entered the ERROR state, any attempt to use the pager
+** to read or write data returns an error. Eventually, once all
+** outstanding transactions have been abandoned, the pager is able to
+** transition back to OPEN state, discarding the contents of the
+** page-cache and any other in-memory state at the same time. Everything
+** is reloaded from disk (and, if necessary, hot-journal rollback peformed)
+** when a read-transaction is next opened on the pager (transitioning
+** the pager into READER state). At that point the system has recovered
+** from the error.
+**
+** Specifically, the pager jumps into the ERROR state if:
+**
+** 1. An error occurs while attempting a rollback. This happens in
+** function sqlite3PagerRollback().
+**
+** 2. An error occurs while attempting to finalize a journal file
+** following a commit in function sqlite3PagerCommitPhaseTwo().
+**
+** 3. An error occurs while attempting to write to the journal or
+** database file in function pagerStress() in order to free up
+** memory.
+**
+** In other cases, the error is returned to the b-tree layer. The b-tree
+** layer then attempts a rollback operation. If the error condition
+** persists, the pager enters the ERROR state via condition (1) above.
+**
+** Condition (3) is necessary because it can be triggered by a read-only
+** statement executed within a transaction. In this case, if the error
+** code were simply returned to the user, the b-tree layer would not
+** automatically attempt a rollback, as it assumes that an error in a
+** read-only statement cannot leave the pager in an internally inconsistent
+** state.
+**
+** * The Pager.errCode variable is set to something other than SQLITE_OK.
+** * There are one or more outstanding references to pages (after the
+** last reference is dropped the pager should move back to OPEN state).
+** * The pager is not an in-memory pager.
+**
+**
+** Notes:
+**
+** * A pager is never in WRITER_DBMOD or WRITER_FINISHED state if the
+** connection is open in WAL mode. A WAL connection is always in one
+** of the first four states.
+**
+** * Normally, a connection open in exclusive mode is never in PAGER_OPEN
+** state. There are two exceptions: immediately after exclusive-mode has
+** been turned on (and before any read or write transactions are
+** executed), and when the pager is leaving the "error state".
+**
+** * See also: assert_pager_state().

+** The Pager.eLock variable is almost always set to one of the
+** following locking-states, according to the lock currently held on
+** the database file: NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
+** This variable is kept up to date as locks are taken and released by
+** the pagerLockDb() and pagerUnlockDb() wrappers.
+**
+** If the VFS xLock() or xUnlock() returns an error other than SQLITE_BUSY
+** (i.e. one of the SQLITE_IOERR subtypes), it is not clear whether or not
+** the operation was successful. In these circumstances pagerLockDb() and
+** pagerUnlockDb() take a conservative approach - eLock is always updated
+** when unlocking the file, and only updated when locking the file if the
+** VFS call is successful. This way, the Pager.eLock variable may be set
+** to a less exclusive (lower) value than the lock that is actually held
+** at the system level, but it is never set to a more exclusive value.
+**
+** This is usually safe. If an xUnlock fails or appears to fail, there may
+** be a few redundant xLock() calls or a lock may be held for longer than
+** required, but nothing really goes wrong.
+**
+** The exception is when the database file is unlocked as the pager moves
+** from ERROR to OPEN state. At this point there may be a hot-journal file
+** in the file-system that needs to be rolled back (as part of a OPEN->SHARED
+** transition, by the same pager or any other). If the call to xUnlock()
+** fails at this point and the pager is left holding an EXCLUSIVE lock, this
+** can confuse the call to xCheckReservedLock() call made later as part
+** of hot-journal detection.
+**
+** xCheckReservedLock() is defined as returning true "if there is a RESERVED
+** lock held by this process or any others". So xCheckReservedLock may
+** return true because the caller itself is holding an EXCLUSIVE lock (but
+** doesn't know it because of a previous error in xUnlock). If this happens
+** a hot-journal may be mistaken for a journal being created by an active
+** transaction in another process, causing SQLite to read from the database
+** without rolling it back.
+**
+** To work around this, if a call to xUnlock() fails when unlocking the
+** database in the ERROR state, Pager.eLock is set to UNKNOWN_LOCK. It
+** is only changed back to a real locking state after a successful call
+** to xLock(EXCLUSIVE). Also, the code to do the OPEN->SHARED state transition
+** omits the check for a hot-journal if Pager.eLock is set to UNKNOWN_LOCK
+** lock. Instead, it assumes a hot-journal exists and obtains an EXCLUSIVE
+** lock on the database file before attempting to roll it back. See function
+** PagerSharedLock() for more detail.
+**
+** Pager.eLock may only be set to UNKNOWN_LOCK when the pager is in
+** PAGER_OPEN state.

+** A open page cache is an instance of struct Pager. A description of
+** some of the more important member variables follows:
+**
+** eState
+**
+** The current 'state' of the pager object. See the comment and state
+** diagram above for a description of the pager state.
+**
+** eLock
+**
+** For a real on-disk database, the current lock held on the database file -
+** NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
+**
+** For a temporary or in-memory database (neither of which require any
+** locks), this variable is always set to EXCLUSIVE_LOCK. Since such
+** databases always have Pager.exclusiveMode==1, this tricks the pager
+** logic into thinking that it already has all the locks it will ever
+** need (and no reason to release them).
+**
+** In some (obscure) circumstances, this variable may also be set to
+** UNKNOWN_LOCK. See the comment above the #define of UNKNOWN_LOCK for
+** details.
+**
+** changeCountDone
+**
+** This boolean variable is used to make sure that the change-counter
+** (the 4-byte header field at byte offset 24 of the database file) is
+** not updated more often than necessary.
+**
+** It is set to true when the change-counter field is updated, which
+** can only happen if an exclusive lock is held on the database file.
+** It is cleared (set to false) whenever an exclusive lock is
+** relinquished on the database file. Each time a transaction is committed,
+** The changeCountDone flag is inspected. If it is true, the work of
+** updating the change-counter is omitted for the current transaction.
+**
+** This mechanism means that when running in exclusive mode, a connection
+** need only update the change-counter once, for the first transaction
+** committed.
+**
+** setMaster
+**
+** When PagerCommitPhaseOne() is called to commit a transaction, it may
+** (or may not) specify a master-journal name to be written into the
+** journal file before it is synced to disk.
+**
+** Whether or not a journal file contains a master-journal pointer affects
+** the way in which the journal file is finalized after the transaction is
+** committed or rolled back when running in "journal_mode=PERSIST" mode.
+** If a journal file does not contain a master-journal pointer, it is
+** finalized by overwriting the first journal header with zeroes. If
+** it does contain a master-journal pointer the journal file is finalized
+** by truncating it to zero bytes, just as if the connection were
+** running in "journal_mode=truncate" mode.
+**
+** Journal files that contain master journal pointers cannot be finalized
+** simply by overwriting the first journal-header with zeroes, as the
+** master journal pointer could interfere with hot-journal rollback of any
+** subsequently interrupted transaction that reuses the journal file.
+**
+** The flag is cleared as soon as the journal file is finalized (either
+** by PagerCommitPhaseTwo or PagerRollback). If an IO error prevents the
+** journal file from being successfully finalized, the setMaster flag
+** is cleared anyway (and the pager will move to ERROR state).
+**
+** doNotSpill, doNotSyncSpill
+**
+** These two boolean variables control the behavior of cache-spills
+** (calls made by the pcache module to the pagerStress() routine to
+** write cached data to the file-system in order to free up memory).
+**
+** When doNotSpill is non-zero, writing to the database from pagerStress()
+** is disabled altogether. This is done in a very obscure case that
+** comes up during savepoint rollback that requires the pcache module
+** to allocate a new page to prevent the journal file from being written
+** while it is being traversed by code in pager_playback().
+**
+** If doNotSyncSpill is non-zero, writing to the database from pagerStress()
+** is permitted, but syncing the journal file is not. This flag is set
+** by sqlite3PagerWrite() when the file-system sector-size is larger than
+** the database page-size in order to prevent a journal sync from happening
+** in between the journalling of two pages on the same sector.
+**
+** subjInMemory
+**
+** This is a boolean variable. If true, then any required sub-journal
+** is opened as an in-memory journal file. If false, then in-memory
+** sub-journals are only used for in-memory pager files.
+**
+** This variable is updated by the upper layer each time a new
+** write-transaction is opened.
+**
+** dbSize, dbOrigSize, dbFileSize
+**
+** Variable dbSize is set to the number of pages in the database file.
+** It is valid in PAGER_READER and higher states (all states except for
+** OPEN and ERROR).
+**
+** dbSize is set based on the size of the database file, which may be
+** larger than the size of the database (the value stored at offset
+** 28 of the database header by the btree). If the size of the file
+** is not an integer multiple of the page-size, the value stored in
+** dbSize is rounded down (i.e. a 5KB file with 2K page-size has dbSize==2).
+** Except, any file that is greater than 0 bytes in size is considered
+** to have at least one page. (i.e. a 1KB file with 2K page-size leads
+** to dbSize==1).
+**
+** During a write-transaction, if pages with page-numbers greater than
+** dbSize are modified in the cache, dbSize is updated accordingly.
+** Similarly, if the database is truncated using PagerTruncateImage(),
+** dbSize is updated.
+**
+** Variables dbOrigSize and dbFileSize are valid in states
+** PAGER_WRITER_LOCKED and higher. dbOrigSize is a copy of the dbSize
+** variable at the start of the transaction. It is used during rollback,
+** and to determine whether or not pages need to be journalled before
+** being modified.
+**
+** Throughout a write-transaction, dbFileSize contains the size of
+** the file on disk in pages. It is set to a copy of dbSize when the
+** write-transaction is first opened, and updated when VFS calls are made
+** to write or truncate the database file on disk.
+**
+** The only reason the dbFileSize variable is required is to suppress
+** unnecessary calls to xTruncate() after committing a transaction. If,
+** when a transaction is committed, the dbFileSize variable indicates
+** that the database file is larger than the database image (Pager.dbSize),
+** pager_truncate() is called. The pager_truncate() call uses xFilesize()
+** to measure the database file on disk, and then truncates it if required.
+** dbFileSize is not used when rolling back a transaction. In this case
+** pager_truncate() is called unconditionally (which means there may be
+** a call to xFilesize() that is not strictly required). In either case,
+** pager_truncate() may cause the file to become smaller or larger.
+**
+** dbHintSize
+**
+** The dbHintSize variable is used to limit the number of calls made to
+** the VFS xFileControl(FCNTL_SIZE_HINT) method.
+**
+** dbHintSize is set to a copy of the dbSize variable when a
+** write-transaction is opened (at the same time as dbFileSize and
+** dbOrigSize). If the xFileControl(FCNTL_SIZE_HINT) method is called,
+** dbHintSize is increased to the number of pages that correspond to the
+** size-hint passed to the method call. See pager_write_pagelist() for
+** details.
+**
+** errCode
+**
+** The Pager.errCode variable is only ever used in PAGER_ERROR state. It
+** is set to zero in all other states. In PAGER_ERROR state, Pager.errCode
+** is always set to SQLITE_FULL, SQLITE_IOERR or one of the SQLITE_IOERR_XXX
+** sub-codes.

+** syncs). If we assume that writing a
+** single disk sector is atomic, then this mode provides

+** was written back into the database. But no sync operations occur for

+** WRITE-AHEAD LOG (WAL) FILE FORMAT
+**
+** A WAL file consists of a header followed by zero or more "frames".
+** Each frame records the revised content of a single page from the
+** database file. All changes to the database are recorded by writing
+** frames into the WAL. Transactions commit when a frame is written that
+** contains a commit marker. A single WAL can and usually does record
+** multiple transactions. Periodically, the content of the WAL is
+** transferred back into the database file in an operation called a
+** "checkpoint".
+**
+** A single WAL file can be used multiple times. In other words, the
+** WAL can fill up with frames and then be checkpointed and then new
+** frames can overwrite the old ones. A WAL always grows from beginning
+** toward the end. Checksums and counters attached to each frame are
+** used to determine which frames within the WAL are valid and which
+** are leftovers from prior checkpoints.
+**
+** The WAL header is 32 bytes in size and consists of the following eight
+** big-endian 32-bit unsigned integer values:
+**
+** 0: Magic number. 0x377f0682 or 0x377f0683
+** 4: File format version. Currently 3007000
+** 8: Database page size. Example: 1024
+** 12: Checkpoint sequence number
+** 16: Salt-1, random integer incremented with each checkpoint
+** 20: Salt-2, a different random integer changing with each ckpt
+** 24: Checksum-1 (first part of checksum for first 24 bytes of header).
+** 28: Checksum-2 (second part of checksum for first 24 bytes of header).
+**
+** Immediately following the wal-header are zero or more frames. Each
+** frame consists of a 24-byte frame-header followed by a <page-size> bytes
+** of page data. The frame-header is six big-endian 32-bit unsigned
+** integer values, as follows:
+**
+** 0: Page number.
+** 4: For commit records, the size of the database image in pages
+** after the commit. For all other records, zero.
+** 8: Salt-1 (copied from the header)
+** 12: Salt-2 (copied from the header)
+** 16: Checksum-1.
+** 20: Checksum-2.
+**
+** A frame is considered valid if and only if the following conditions are
+** true:
+**
+** (1) The salt-1 and salt-2 values in the frame-header match
+** salt values in the wal-header
+**
+** (2) The checksum values in the final 8 bytes of the frame-header
+** exactly match the checksum computed consecutively on the
+** WAL header and the first 8 bytes and the content of all frames
+** up to and including the current frame.
+**
+** The checksum is computed using 32-bit big-endian integers if the
+** magic number in the first 4 bytes of the WAL is 0x377f0683 and it
+** is computed using little-endian if the magic number is 0x377f0682.
+** The checksum values are always stored in the frame header in a
+** big-endian format regardless of which byte order is used to compute
+** the checksum. The checksum is computed by interpreting the input as
+** an even number of unsigned 32-bit integers: x[0] through x[N]. The
+** algorithm used for the checksum is as follows:
+**
+** for i from 0 to n-1 step 2:
+** s0 += x[i] + s1;
+** s1 += x[i+1] + s0;
+** endfor
+**
+** Note that s0 and s1 are both weighted checksums using fibonacci weights
+** in reverse order (the largest fibonacci weight occurs on the first element
+** of the sequence being summed.) The s1 value spans all 32-bit
+** terms of the sequence whereas s0 omits the final term.
+**
+** On a checkpoint, the WAL is first VFS.xSync-ed, then valid content of the
+** WAL is transferred into the database, then the database is VFS.xSync-ed.
+** The VFS.xSync operations serve as write barriers - all writes launched
+** before the xSync must complete before any write that launches after the
+** xSync begins.
+**
+** After each checkpoint, the salt-1 value is incremented and the salt-2
+** value is randomized. This prevents old and new frames in the WAL from
+** being considered valid at the same time and being checkpointing together
+** following a crash.
+**
+** READER ALGORITHM
+**
+** To read a page from the database (call it page number P), a reader
+** first checks the WAL to see if it contains page P. If so, then the
+** last valid instance of page P that is a followed by a commit frame
+** or is a commit frame itself becomes the value read. If the WAL
+** contains no copies of page P that are valid and which are a commit
+** frame or are followed by a commit frame, then page P is read from
+** the database file.
+**
+** To start a read transaction, the reader records the index of the last
+** valid frame in the WAL. The reader uses this recorded "mxFrame" value
+** for all subsequent read operations. New transactions can be appended
+** to the WAL, but as long as the reader uses its original mxFrame value
+** and ignores the newly appended content, it will see a consistent snapshot
+** of the database from a single point in time. This technique allows
+** multiple concurrent readers to view different versions of the database
+** content simultaneously.
+**
+** The reader algorithm in the previous paragraphs works correctly, but
+** because frames for page P can appear anywhere within the WAL, the
+** reader has to scan the entire WAL looking for page P frames. If the
+** WAL is large (multiple megabytes is typical) that scan can be slow,
+** and read performance suffers. To overcome this problem, a separate
+** data structure called the wal-index is maintained to expedite the
+** search for frames of a particular page.
+**
+** WAL-INDEX FORMAT
+**
+** Conceptually, the wal-index is shared memory, though VFS implementations
+** might choose to implement the wal-index using a mmapped file. Because
+** the wal-index is shared memory, SQLite does not support journal_mode=WAL
+** on a network filesystem. All users of the database must be able to
+** share memory.
+**
+** The wal-index is transient. After a crash, the wal-index can (and should
+** be) reconstructed from the original WAL file. In fact, the VFS is required
+** to either truncate or zero the header of the wal-index when the last
+** connection to it closes. Because the wal-index is transient, it can
+** use an architecture-specific format; it does not have to be cross-platform.
+** Hence, unlike the database and WAL file formats which store all values
+** as big endian, the wal-index can store multi-byte values in the native
+** byte order of the host computer.
+**
+** The purpose of the wal-index is to answer this question quickly: Given
+** a page number P and a maximum frame index M, return the index of the
+** last frame in the wal before frame M for page P in the WAL, or return
+** NULL if there are no frames for page P in the WAL prior to M.
+**
+** The wal-index consists of a header region, followed by an one or
+** more index blocks.
+**
+** The wal-index header contains the total number of frames within the WAL
+** in the mxFrame field.
+**
+** Each index block except for the first contains information on
+** HASHTABLE_NPAGE frames. The first index block contains information on
+** HASHTABLE_NPAGE_ONE frames. The values of HASHTABLE_NPAGE_ONE and
+** HASHTABLE_NPAGE are selected so that together the wal-index header and
+** first index block are the same size as all other index blocks in the
+** wal-index.
+**
+** Each index block contains two sections, a page-mapping that contains the
+** database page number associated with each wal frame, and a hash-table
+** that allows readers to query an index block for a specific page number.
+** The page-mapping is an array of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE
+** for the first index block) 32-bit page numbers. The first entry in the
+** first index-block contains the database page number corresponding to the
+** first frame in the WAL file. The first entry in the second index block
+** in the WAL file corresponds to the (HASHTABLE_NPAGE_ONE+1)th frame in
+** the log, and so on.
+**
+** The last index block in a wal-index usually contains less than the full
+** complement of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE) page-numbers,
+** depending on the contents of the WAL file. This does not change the
+** allocated size of the page-mapping array - the page-mapping array merely
+** contains unused entries.
+**
+** Even without using the hash table, the last frame for page P
+** can be found by scanning the page-mapping sections of each index block
+** starting with the last index block and moving toward the first, and
+** within each index block, starting at the end and moving toward the
+** beginning. The first entry that equals P corresponds to the frame
+** holding the content for that page.
+**
+** The hash table consists of HASHTABLE_NSLOT 16-bit unsigned integers.
+** HASHTABLE_NSLOT = 2*HASHTABLE_NPAGE, and there is one entry in the
+** hash table for each page number in the mapping section, so the hash
+** table is never more than half full. The expected number of collisions
+** prior to finding a match is 1. Each entry of the hash table is an
+** 1-based index of an entry in the mapping section of the same
+** index block. Let K be the 1-based index of the largest entry in
+** the mapping section. (For index blocks other than the last, K will
+** always be exactly HASHTABLE_NPAGE (4096) and for the last index block
+** K will be (mxFrame%HASHTABLE_NPAGE).) Unused slots of the hash table
+** contain a value of 0.
+**
+** To look for page P in the hash table, first compute a hash iKey on
+** P as follows:
+**
+** iKey = (P * 383) % HASHTABLE_NSLOT
+**
+** Then start scanning entries of the hash table, starting with iKey
+** (wrapping around to the beginning when the end of the hash table is
+** reached) until an unused hash slot is found. Let the first unused slot
+** be at index iUnused. (iUnused might be less than iKey if there was
+** wrap-around.) Because the hash table is never more than half full,
+** the search is guaranteed to eventually hit an unused entry. Let
+** iMax be the value between iKey and iUnused, closest to iUnused,
+** where aHash[iMax]==P. If there is no iMax entry (if there exists
+** no hash slot such that aHash[i]==p) then page P is not in the
+** current index block. Otherwise the iMax-th mapping entry of the
+** current index block corresponds to the last entry that references
+** page P.
+**
+** A hash search begins with the last index block and moves toward the
+** first index block, looking for entries corresponding to page P. On
+** average, only two or three slots in each index block need to be
+** examined in order to either find the last entry for page P, or to
+** establish that no such entry exists in the block. Each index block
+** holds over 4000 entries. So two or three index blocks are sufficient
+** to cover a typical 10 megabyte WAL file, assuming 1K pages. 8 or 10
+** comparisons (on average) suffice to either locate a frame in the
+** WAL or to establish that the frame does not exist in the WAL. This
+** is much faster than scanning the entire 10MB WAL.
+**
+** Note that entries are added in order of increasing K. Hence, one
+** reader might be using some value K0 and a second reader that started
+** at a later time (after additional transactions were added to the WAL
+** and to the wal-index) might be using a different value K1, where K1>K0.
+** Both readers can use the same hash table and mapping section to get
+** the correct result. There may be entries in the hash table with
+** K>K0 but to the first reader, those entries will appear to be unused
+** slots in the hash table and so the first reader will get an answer as
+** if no values greater than K0 had ever been inserted into the hash table
+** in the first place - which is what reader one wants. Meanwhile, the
+** second reader using K1 will see additional values that were inserted
+** later, which is exactly what reader two wants.
+**
+** When a rollback occurs, the value of K is decreased. Hash table entries
+** that correspond to frames greater than the new K value are removed
+** from the hash table at this point.

+**
+** There is one entry in aReadMark[] for each reader lock. If a reader

+** a special case; its value is never used and it exists as a place-holder
+** to avoid having to offset aReadMark[] indexs by one. Readers holding

+** The value of aReadMark[K] may only be changed by a thread that

+** For a detailed discussion of BTrees, refer to
+**
+** Donald E. Knuth, THE ART OF COMPUTER PROGRAMMING, Volume 3:
+** "Sorting And Searching", pages 473-480. Addison-Wesley
+** Publishing Company, Reading, Massachusetts.
+**
+** The basic idea is that each page of the file contains N database
+** entries and N+1 pointers to subpages.
+**
+** ----------------------------------------------------------------
+** | Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N-1) | Ptr(N) |
+** ----------------------------------------------------------------
+**
+** All of the keys on the page that Ptr(0) points to have values less
+** than Key(0). All of the keys on page Ptr(1) and its subpages have
+** values greater than Key(0) and less than Key(1). All of the keys
+** on Ptr(N) and its subpages have values greater than Key(N-1). And
+** so forth.
+**
+** Finding a particular key requires reading O(log(M)) pages from the
+** disk where M is the number of entries in the tree.
+**
+** In this implementation, a single file can hold one or more separate
+** BTrees. Each BTree is identified by the index of its root page. The
+** key and data for any entry are combined to form the "payload". A
+** fixed amount of payload can be carried directly on the database
+** page. If the payload is larger than the preset amount then surplus
+** bytes are stored on overflow pages. The payload for an entry
+** and the preceding pointer are combined to form a "Cell". Each
+** page has a small header which contains the Ptr(N) pointer and other
+** information such as the size of key and data.
+**
+** FORMAT DETAILS
+**
+** The file is divided into pages. The first page is called page 1,
+** the second is page 2, and so forth. A page number of zero indicates
+** "no such page". The page size can be any power of 2 between 512 and 65536.
+** Each page can be either a btree page, a freelist page, an overflow
+** page, or a pointer-map page.
+**
+** The first page is always a btree page. The first 100 bytes of the first
+** page contain a special header (the "file header") that describes the file.
+** The format of the file header is as follows:
+**
+** OFFSET SIZE DESCRIPTION
+** 0 16 Header string: "SQLite format 3\000"
+** 16 2 Page size in bytes.
+** 18 1 File format write version
+** 19 1 File format read version
+** 20 1 Bytes of unused space at the end of each page
+** 21 1 Max embedded payload fraction
+** 22 1 Min embedded payload fraction
+** 23 1 Min leaf payload fraction
+** 24 4 File change counter
+** 28 4 Reserved for future use
+** 32 4 First freelist page
+** 36 4 Number of freelist pages in the file
+** 40 60 15 4-byte meta values passed to higher layers
+**
+** 40 4 Schema cookie
+** 44 4 File format of schema layer
+** 48 4 Size of page cache
+** 52 4 Largest root-page (auto/incr_vacuum)
+** 56 4 1=UTF-8 2=UTF16le 3=UTF16be
+** 60 4 User version
+** 64 4 Incremental vacuum mode
+** 68 4 unused
+** 72 4 unused
+** 76 4 unused
+**
+** All of the integer values are big-endian (most significant byte first).
+**
+** The file change counter is incremented when the database is changed
+** This counter allows other processes to know when the file has changed
+** and thus when they need to flush their cache.
+**
+** The max embedded payload fraction is the amount of the total usable
+** space in a page that can be consumed by a single cell for standard
+** B-tree (non-LEAFDATA) tables. A value of 255 means 100%. The default
+** is to limit the maximum cell size so that at least 4 cells will fit
+** on one page. Thus the default max embedded payload fraction is 64.
+**
+** If the payload for a cell is larger than the max payload, then extra
+** payload is spilled to overflow pages. Once an overflow page is allocated,
+** as many bytes as possible are moved into the overflow pages without letting
+** the cell size drop below the min embedded payload fraction.
+**
+** The min leaf payload fraction is like the min embedded payload fraction
+** except that it applies to leaf nodes in a LEAFDATA tree. The maximum
+** payload fraction for a LEAFDATA tree is always 100% (or 255) and it
+** not specified in the header.
+**
+** Each btree pages is divided into three sections: The header, the
+** cell pointer array, and the cell content area. Page 1 also has a 100-byte
+** file header that occurs before the page header.
+**
+** |----------------|
+** | file header | 100 bytes. Page 1 only.
+** |----------------|
+** | page header | 8 bytes for leaves. 12 bytes for interior nodes
+** |----------------|
+** | cell pointer | | 2 bytes per cell. Sorted order.
+** | array | | Grows downward
+** | | v
+** |----------------|
+** | unallocated |
+** | space |
+** |----------------| ^ Grows upwards
+** | cell content | | Arbitrary order interspersed with freeblocks.
+** | area | | and free space fragments.
+** |----------------|
+**
+** The page headers looks like this:
+**
+** OFFSET SIZE DESCRIPTION
+** 0 1 Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf
+** 1 2 byte offset to the first freeblock
+** 3 2 number of cells on this page
+** 5 2 first byte of the cell content area
+** 7 1 number of fragmented free bytes
+** 8 4 Right child (the Ptr(N) value). Omitted on leaves.
+**
+** The flags define the format of this btree page. The leaf flag means that
+** this page has no children. The zerodata flag means that this page carries
+** only keys and no data. The intkey flag means that the key is a integer
+** which is stored in the key size entry of the cell header rather than in
+** the payload area.
+**
+** The cell pointer array begins on the first byte after the page header.
+** The cell pointer array contains zero or more 2-byte numbers which are
+** offsets from the beginning of the page to the cell content in the cell
+** content area. The cell pointers occur in sorted order. The system strives
+** to keep free space after the last cell pointer so that new cells can
+** be easily added without having to defragment the page.
+**
+** Cell content is stored at the very end of the page and grows toward the
+** beginning of the page.
+**
+** Unused space within the cell content area is collected into a linked list of
+** freeblocks. Each freeblock is at least 4 bytes in size. The byte offset
+** to the first freeblock is given in the header. Freeblocks occur in
+** increasing order. Because a freeblock must be at least 4 bytes in size,
+** any group of 3 or fewer unused bytes in the cell content area cannot
+** exist on the freeblock chain. A group of 3 or fewer free bytes is called
+** a fragment. The total number of bytes in all fragments is recorded.
+** in the page header at offset 7.
+**
+** SIZE DESCRIPTION
+** 2 Byte offset of the next freeblock
+** 2 Bytes in this freeblock
+**
+** Cells are of variable length. Cells are stored in the cell content area at
+** the end of the page. Pointers to the cells are in the cell pointer array
+** that immediately follows the page header. Cells is not necessarily
+** contiguous or in order, but cell pointers are contiguous and in order.
+**
+** Cell content makes use of variable length integers. A variable
+** length integer is 1 to 9 bytes where the lower 7 bits of each
+** byte are used. The integer consists of all bytes that have bit 8 set and
+** the first byte with bit 8 clear. The most significant byte of the integer
+** appears first. A variable-length integer may not be more than 9 bytes long.
+** As a special case, all 8 bytes of the 9th byte are used as data. This
+** allows a 64-bit integer to be encoded in 9 bytes.
+**
+** 0x00 becomes 0x00000000
+** 0x7f becomes 0x0000007f
+** 0x81 0x00 becomes 0x00000080
+** 0x82 0x00 becomes 0x00000100
+** 0x80 0x7f becomes 0x0000007f
+** 0x8a 0x91 0xd1 0xac 0x78 becomes 0x12345678
+** 0x81 0x81 0x81 0x81 0x01 becomes 0x10204081
+**
+** Variable length integers are used for rowids and to hold the number of
+** bytes of key and data in a btree cell.
+**
+** The content of a cell looks like this:
+**
+** SIZE DESCRIPTION
+** 4 Page number of the left child. Omitted if leaf flag is set.
+** var Number of bytes of data. Omitted if the zerodata flag is set.
+** var Number of bytes of key. Or the key itself if intkey flag is set.
+** * Payload
+** 4 First page of the overflow chain. Omitted if no overflow
+**
+** Overflow pages form a linked list. Each page except the last is completely
+** filled with data (pagesize - 4 bytes). The last page can have as little
+** as 1 byte of data.
+**
+** SIZE DESCRIPTION
+** 4 Page number of next overflow page
+** * Data
+**
+** Freelist pages come in two subtypes: trunk pages and leaf pages. The
+** file header points to the first in a linked list of trunk page. Each trunk
+** page points to multiple leaf pages. The content of a leaf page is
+** unspecified. A trunk page looks like this:
+**
+** SIZE DESCRIPTION
+** 4 Page number of next trunk page
+** 4 Number of leaf pointers on this page
+** * zero or more pages numbers of leaves

+** free-list leaf pages:
+**
+** 1) When all data is deleted from a page and the page becomes
+** a free-list leaf page, the page is not written to the database
+** (as free-list leaf pages contain no meaningful data). Sometimes
+** such a page is not even journalled (as it will not be modified,
+** why bother journalling it?).
+**
+** 2) When a free-list leaf page is reused, its content is not read
+** from the database or written to the journal file (why should it
+** be, if it is not at all meaningful?).
+**
+** By themselves, these optimizations work fine and provide a handy
+** performance boost to bulk delete or insert operations. However, if
+** a page is moved to the free-list and then reused within the same
+** transaction, a problem comes up. If the page is not journalled when
+** it is moved to the free-list and it is also not journalled when it
+** is extracted from the free-list and reused, then the original data
+** may be lost. In the event of a rollback, it may not be possible
+** to restore the database to its original configuration.
+**
+** The solution is the BtShared.pHasContent bitvec. Whenever a page is
+** moved to become a free-list leaf page, the corresponding bit is
+** set in the bitvec. Whenever a leaf page is extracted from the free-list,

+** What follows is a massive switch statement where each case implements a

+** the switch statement will break with convention and be flush-left. Another
+** big comment (similar to this one) will mark the point in the code where
+** we transition back to normal indentation.
+**
+** The formatting of each case is important. The makefile for SQLite
+** generates two C files "opcodes.h" and "opcodes.c" by scanning this
+** file looking for lines that begin with "case OP_". The opcodes.h files
+** will be filled with #defines that give unique integer values to each
+** opcode and the opcodes.c file is filled with an array of strings where
+** each string is the symbolic name for the corresponding opcode. If the
+** case statement is followed by a comment of the form "/# same as ... #/"
+** that comment is used to determine the particular value of the opcode.
+**
+** Other keywords in the comment that follows each case are used to
+** construct the OPFLG_INITIALIZER value that initializes opcodeProperty[].
+** Keywords include: in1, in2, in3, out2_prerelease, out2, out3. See
+** the mkopcodeh.awk script for additional information.
+**
+** Documentation about VDBE opcodes is generated by scanning this file

+** NOTES ON DATA STRUCTURE USED FOR N-WAY MERGES:
+**
+** As keys are added to the sorter, they are written to disk in a series
+** of sorted packed-memory-arrays (PMAs). The size of each PMA is roughly
+** the same as the cache-size allowed for temporary databases. In order
+** to allow the caller to extract keys from the sorter in sorted order,
+** all PMAs currently stored on disk must be merged together. This comment
+** describes the data structure used to do so. The structure supports
+** merging any number of arrays in a single pass with no redundant comparison
+** operations.
+**
+** The aIter[] array contains an iterator for each of the PMAs being merged.
+** An aIter[] iterator either points to a valid key or else is at EOF. For
+** the purposes of the paragraphs below, we assume that the array is actually
+** N elements in size, where N is the smallest power of 2 greater to or equal
+** to the number of iterators being merged. The extra aIter[] elements are
+** treated as if they are empty (always at EOF).
+**
+** The aTree[] array is also N elements in size. The value of N is stored in
+** the VdbeSorter.nTree variable.
+**
+** The final (N/2) elements of aTree[] contain the results of comparing
+** pairs of iterator keys together. Element i contains the result of
+** comparing aIter[2*i-N] and aIter[2*i-N+1]. Whichever key is smaller, the
+** aTree element is set to the index of it.
+**
+** For the purposes of this comparison, EOF is considered greater than any
+** other key value. If the keys are equal (only possible with two EOF
+** values), it doesn't matter which index is stored.
+**
+** The (N/4) elements of aTree[] that preceed the final (N/2) described
+** above contains the index of the smallest of each block of 4 iterators.
+** And so on. So that aTree[1] contains the index of the iterator that
+** currently points to the smallest key value. aTree[0] is unused.
+**
+** Example:
+**
+** aIter[0] -> Banana
+** aIter[1] -> Feijoa
+** aIter[2] -> Elderberry
+** aIter[3] -> Currant
+** aIter[4] -> Grapefruit
+** aIter[5] -> Apple
+** aIter[6] -> Durian
+** aIter[7] -> EOF
+**
+** aTree[] = { X, 5 0, 5 0, 3, 5, 6 }
+**
+** The current element is "Apple" (the value of the key indicated by
+** iterator 5). When the Next() operation is invoked, iterator 5 will
+** be advanced to the next key in its segment. Say the next key is
+** "Eggplant":
+**
+** aIter[5] -> Eggplant
+**
+** The contents of aTree[] are updated first by comparing the new iterator
+** 5 key to the current key of iterator 4 (still "Grapefruit"). The iterator
+** 5 value is still smaller, so aTree[6] is set to 5. And so on up the tree.
+** The value of iterator 6 - "Durian" - is now smaller than that of iterator
+** 5, so aTree[3] is set to 6. Key 0 is smaller than key 6 (Banana<Durian),
+** so the value written into element 1 of the array is 0. As follows:
+**
+** aTree[] = { X, 0 0, 6 0, 3, 5, 6 }
+**
+** In other words, each time we advance to the next sorter element, log2(N)
+** key comparison operations are required, where N is the number of segments
+** being merged (rounded up to the next power of 2).

+** SELECT a+b, c+d FROM t1 ORDER BY (a+b) COLLATE nocase;

+** This routine walks an expression tree and resolves references to

+** are seen.
+**
+** To resolve table columns references we look for nodes (or subtrees) of the
+** form X.Y.Z or Y.Z or just Z where
+**
+** X: The name of a database. Ex: "main" or "temp" or
+** the symbolic name assigned to an ATTACH-ed database.
+**
+** Y: The name of a table in a FROM clause. Or in a trigger
+** one of the special names "old" or "new".
+**
+** Z: The name of a column in table Y.
+**
+** The node at the root of the subtree is modified as follows:
+**
+** Expr.op Changed to TK_COLUMN
+** Expr.pTab Points to the Table object for X.Y
+** Expr.iColumn The column index in X.Y. -1 for the rowid.
+** Expr.iTable The VDBE cursor number for X.Y
+**
+**
+** To resolve result-set references, look for expression nodes of the
+** form Z (with no X and Y prefix) where the Z matches the right-hand
+** size of an AS clause in the result-set of a SELECT. The Z expression
+** is replaced by a copy of the left-hand side of the result-set expression.
+** Table-name and function resolution occurs on the substituted expression
+** tree. For example, in:
+**
+** SELECT a+b AS x, c+d AS y FROM t1 ORDER BY x;
+**
+** The "x" term of the order by is replaced by "a+b" to render:
+**
+** SELECT a+b AS x, c+d AS y FROM t1 ORDER BY a+b;
+**
+** Function calls are checked to make sure that the function is
+** defined and that the correct number of arguments are specified.
+** If the function is an aggregate function, then the NC_HasAgg flag is
+** set and the opcode is changed from TK_FUNCTION to TK_AGG_FUNCTION.
+** If an expression contains aggregate functions then the EP_Agg
+** property on the expression is set.

+** An error message is left in pParse if anything is amiss. The number

+** This function is used by the implementation of the IN (...) operator.

+**
+** The job of this routine is to find or create a b-tree object that can
+** be used either to test for membership in the RHS set or to iterate through
+** all members of the RHS set, skipping duplicates.
+**
+** A cursor is opened on the b-tree object that the RHS of the IN operator
+** and pX->iTable is set to the index of that cursor.
+**
+** The returned value of this function indicates the b-tree type, as follows:
+**
+** IN_INDEX_ROWID - The cursor was opened on a database table.
+** IN_INDEX_INDEX_ASC - The cursor was opened on an ascending index.
+** IN_INDEX_INDEX_DESC - The cursor was opened on a descending index.
+** IN_INDEX_EPH - The cursor was opened on a specially created and
+** populated epheremal table.
+**
+** An existing b-tree might be used if the RHS expression pX is a simple
+** subquery such as:
+**
+** SELECT <column> FROM <table>
+**
+** If the RHS of the IN operator is a list or a more complex subquery, then
+** an ephemeral table might need to be generated from the RHS and then
+** pX->iTable made to point to the ephermeral table instead of an
+** existing table.
+**
+** If the prNotFound parameter is 0, then the b-tree will be used to iterate
+** through the set members, skipping any duplicates. In this case an
+** epheremal table must be used unless the selected <column> is guaranteed
+** to be unique - either because it is an INTEGER PRIMARY KEY or it
+** has a UNIQUE constraint or UNIQUE index.
+**
+** If the prNotFound parameter is not 0, then the b-tree will be used
+** for fast set membership tests. In this case an epheremal table must
+** be used unless <column> is an INTEGER PRIMARY KEY or an index can
+** be found with <column> as its left-most column.
+**
+** When the b-tree is being used for membership tests, the calling function
+** needs to know whether or not the structure contains an SQL NULL
+** value in order to correctly evaluate expressions like "X IN (Y, Z)".
+** If there is any chance that the (...) might contain a NULL value at
+** runtime, then a register is allocated and the register number written
+** to *prNotFound. If there is no chance that the (...) contains a
+** NULL value, then *prNotFound is left unchanged.
+**
+** If a register is allocated and its location stored in *prNotFound, then
+** its initial value is NULL. If the (...) does not remain constant
+** for the duration of the query (i.e. the SELECT within the (...)
+** is a correlated subquery) then the value of the allocated register is
+** reset to NULL each time the subquery is rerun. This allows the
+** caller to use vdbe code equivalent to the following:
+**
+** if( register==NULL ){
+** has_null = <test if data structure contains null>
+** register = 1
+** }
+**
+** in order to avoid running the <test if data structure contains null>

+*************************************************************************
+** This file contains code associated with the ANALYZE command.
+**
+** The ANALYZE command gather statistics about the content of tables
+** and indices. These statistics are made available to the query planner
+** to help it make better decisions about how to perform queries.
+**
+** The following system tables are or have been supported:
+**
+** CREATE TABLE sqlite_stat1(tbl, idx, stat);
+** CREATE TABLE sqlite_stat2(tbl, idx, sampleno, sample);
+** CREATE TABLE sqlite_stat3(tbl, idx, nEq, nLt, nDLt, sample);
+**
+** Additional tables might be added in future releases of SQLite.
+** The sqlite_stat2 table is not created or used unless the SQLite version
+** is between 3.6.18 and 3.7.8, inclusive, and unless SQLite is compiled
+** with SQLITE_ENABLE_STAT2. The sqlite_stat2 table is deprecated.
+** The sqlite_stat2 table is superceded by sqlite_stat3, which is only
+** created and used by SQLite versions 3.7.9 and later and with
+** SQLITE_ENABLE_STAT3 defined. The fucntionality of sqlite_stat3
+** is a superset of sqlite_stat2.
+**
+** Format of sqlite_stat1:
+**
+** There is normally one row per index, with the index identified by the
+** name in the idx column. The tbl column is the name of the table to
+** which the index belongs. In each such row, the stat column will be
+** a string consisting of a list of integers. The first integer in this
+** list is the number of rows in the index and in the table. The second
+** integer is the average number of rows in the index that have the same
+** value in the first column of the index. The third integer is the average
+** number of rows in the index that have the same value for the first two
+** columns. The N-th integer (for N>1) is the average number of rows in
+** the index which have the same value for the first N-1 columns. For
+** a K-column index, there will be K+1 integers in the stat column. If
+** the index is unique, then the last integer will be 1.
+**
+** The list of integers in the stat column can optionally be followed
+** by the keyword "unordered". The "unordered" keyword, if it is present,
+** must be separated from the last integer by a single space. If the
+** "unordered" keyword is present, then the query planner assumes that
+** the index is unordered and will not use the index for a range query.
+**
+** If the sqlite_stat1.idx column is NULL, then the sqlite_stat1.stat
+** column contains a single integer which is the (estimated) number of
+** rows in the table identified by sqlite_stat1.tbl.
+**
+** Format of sqlite_stat2:
+**
+** The sqlite_stat2 is only created and is only used if SQLite is compiled
+** with SQLITE_ENABLE_STAT2 and if the SQLite version number is between
+** 3.6.18 and 3.7.8. The "stat2" table contains additional information
+** about the distribution of keys within an index. The index is identified by
+** the "idx" column and the "tbl" column is the name of the table to which
+** the index belongs. There are usually 10 rows in the sqlite_stat2
+** table for each index.
+**
+** The sqlite_stat2 entries for an index that have sampleno between 0 and 9
+** inclusive are samples of the left-most key value in the index taken at
+** evenly spaced points along the index. Let the number of samples be S
+** (10 in the standard build) and let C be the number of rows in the index.
+** Then the sampled rows are given by:
+**
+** rownumber = (i*C*2 + C)/(S*2)
+**
+** For i between 0 and S-1. Conceptually, the index space is divided into
+** S uniform buckets and the samples are the middle row from each bucket.
+**
+** The format for sqlite_stat2 is recorded here for legacy reference. This
+** version of SQLite does not support sqlite_stat2. It neither reads nor
+** writes the sqlite_stat2 table. This version of SQLite only supports
+** sqlite_stat3.
+**
+** Format for sqlite_stat3:
+**
+** The sqlite_stat3 is an enhancement to sqlite_stat2. A new name is
+** used to avoid compatibility problems.
+**
+** The format of the sqlite_stat3 table is similar to the format of
+** the sqlite_stat2 table. There are multiple entries for each index.
+** The idx column names the index and the tbl column is the table of the
+** index. If the idx and tbl columns are the same, then the sample is
+** of the INTEGER PRIMARY KEY. The sample column is a value taken from
+** the left-most column of the index. The nEq column is the approximate
+** number of entires in the index whose left-most column exactly matches
+** the sample. nLt is the approximate number of entires whose left-most
+** column is less than the sample. The nDLt column is the approximate
+** number of distinct left-most entries in the index that are less than
+** the sample.
+**
+** Future versions of SQLite might change to store a string containing
+** multiple integers values in the nDLt column of sqlite_stat3. The first
+** integer will be the number of prior index entires that are distinct in
+** the left-most column. The second integer will be the number of prior index
+** entries that are distinct in the first two columns. The third integer
+** will be the number of prior index entries that are distinct in the first
+** three columns. And so forth. With that extension, the nDLt field is
+** similar in function to the sqlite_stat1.stat field.
+**
+** There can be an arbitrary number of sqlite_stat3 entries per index.
+** The ANALYZE command will typically generate sqlite_stat3 tables
+** that contain between 10 and 40 samples which are distributed across
+** the key space, though not uniformly, and which include samples with
+** largest possible nEq values.

+** Deferred and Immediate FKs
+** --------------------------
+**
+** Foreign keys in SQLite come in two flavours: deferred and immediate.
+** If an immediate foreign key constraint is violated,
+** SQLITE_CONSTRAINT_FOREIGNKEY is returned and the current
+** statement transaction rolled back. If a
+** deferred foreign key constraint is violated, no action is taken
+** immediately. However if the application attempts to commit the
+** transaction before fixing the constraint violation, the attempt fails.
+**
+** Deferred constraints are implemented using a simple counter associated
+** with the database handle. The counter is set to zero each time a
+** database transaction is opened. Each time a statement is executed
+** that causes a foreign key violation, the counter is incremented. Each
+** time a statement is executed that removes an existing violation from
+** the database, the counter is decremented. When the transaction is
+** committed, the commit fails if the current value of the counter is
+** greater than zero. This scheme has two big drawbacks:
+**
+** * When a commit fails due to a deferred foreign key constraint,
+** there is no way to tell which foreign constraint is not satisfied,
+** or which row it is not satisfied for.
+**
+** * If the database contains foreign key violations when the
+** transaction is opened, this may cause the mechanism to malfunction.
+**
+** Despite these problems, this approach is adopted as it seems simpler
+** than the alternatives.
+**
+** INSERT operations:
+**
+** I.1) For each FK for which the table is the child table, search
+** the parent table for a match. If none is found increment the
+** constraint counter.
+**
+** I.2) For each FK for which the table is the parent table,
+** search the child table for rows that correspond to the new
+** row in the parent table. Decrement the counter for each row
+** found (as the constraint is now satisfied).
+**
+** DELETE operations:
+**
+** D.1) For each FK for which the table is the child table,
+** search the parent table for a row that corresponds to the
+** deleted row in the child table. If such a row is not found,
+** decrement the counter.
+**
+** D.2) For each FK for which the table is the parent table, search
+** the child table for rows that correspond to the deleted row
+** in the parent table. For each found increment the counter.
+**
+** UPDATE operations:
+**
+** An UPDATE command requires that all 4 steps above are taken, but only
+** for FK constraints for which the affected columns are actually
+** modified (values must be compared at runtime).
+**
+** Note that I.1 and D.1 are very similar operations, as are I.2 and D.2.
+** This simplifies the implementation a bit.
+**
+** For the purposes of immediate FK constraints, the OR REPLACE conflict
+** resolution is considered to delete rows before the new row is inserted.
+** If a delete caused by OR REPLACE violates an FK constraint, an exception
+** is thrown, even if the FK constraint would be satisfied after the new
+** row is inserted.
+**
+** Immediate constraints are usually handled similarly. The only difference
+** is that the counter used is stored as part of each individual statement
+** object (struct Vdbe). If, after the statement has run, its immediate
+** constraint counter is greater than zero,
+** it returns SQLITE_CONSTRAINT_FOREIGNKEY
+** and the statement transaction is rolled back. An exception is an INSERT
+** statement that inserts a single row only (no triggers). In this case,
+** instead of using a counter, an exception is thrown immediately if the
+** INSERT violates a foreign key constraint. This is necessary as such
+** an INSERT does not open a statement transaction.
+**
+** TODO: How should dropping a table be handled? How should renaming a
+** table be handled?
+**
+**
+** Query API Notes
+** ---------------
+**
+** Before coding an UPDATE or DELETE row operation, the code-generator
+** for those two operations needs to know whether or not the operation
+** requires any FK processing and, if so, which columns of the original
+** row are required by the FK processing VDBE code (i.e. if FKs were
+** implemented using triggers, which of the old.* columns would be
+** accessed). No information is required by the code-generator before
+** coding an INSERT operation. The functions used by the UPDATE/DELETE
+** generation code to query for this information are:
+**
+** sqlite3FkRequired() - Test to see if FK processing is required.
+** sqlite3FkOldmask() - Query for the set of required old.* columns.
+**
+**
+** Externally accessible module functions
+** --------------------------------------
+**
+** sqlite3FkCheck() - Check for foreign key violations.
+** sqlite3FkActions() - Code triggers for ON UPDATE/ON DELETE actions.
+** sqlite3FkDelete() - Delete an FKey structure.
+*/
+
+/*
+** VDBE Calling Convention
+** -----------------------
+**
+** Example:
+**
+** For the following INSERT statement:
+**
+** CREATE TABLE t1(a, b INTEGER PRIMARY KEY, c);
+** INSERT INTO t1 VALUES(1, 2, 3.1);
+**
+** Register (x): 2 (type integer)
+** Register (x+1): 1 (type integer)
+** Register (x+2): NULL (type NULL)
+** Register (x+3): 3.1 (type real)
+*/
+
+/*
+** A foreign key constraint requires that the key columns in the parent
+** table are collectively subject to a UNIQUE or PRIMARY KEY constraint.
+** Given that pParent is the parent table for foreign key constraint pFKey,
+** search the schema for a unique index on the parent key columns.
+**
+** If successful, zero is returned. If the parent key is an INTEGER PRIMARY
+** KEY column, then output variable *ppIdx is set to NULL. Otherwise, *ppIdx
+** is set to point to the unique index.
+**
+** If the parent key consists of a single column (the foreign key constraint
+** is not a composite foreign key), output variable *paiCol is set to NULL.
+** Otherwise, it is set to point to an allocated array of size N, where
+** N is the number of columns in the parent key. The first element of the
+** array is the index of the child table column that is mapped by the FK
+** constraint to the parent table column stored in the left-most column
+** of index *ppIdx. The second element of the array is the index of the
+** child table column that corresponds to the second left-most column of
+** *ppIdx, and so on.
+**
+** If the required index cannot be found, either because:
+**
+** 1) The named parent key columns do not exist, or
+**
+** 2) The named parent key columns do exist, but are not subject to a
+** UNIQUE or PRIMARY KEY constraint, or
+**
+** 3) No parent key columns were provided explicitly as part of the
+** foreign key definition, and the parent table does not have a
+** PRIMARY KEY, or
+**
+** 4) No parent key columns were provided explicitly as part of the
+** foreign key definition, and the PRIMARY KEY of the parent table
+** consists of a a different number of columns to the child key in
+** the child table.
+**
+** then non-zero is returned, and a "foreign key mismatch" error loaded
+** into pParse. If an OOM error occurs, non-zero is returned and the
+** pParse->db->mallocFailed flag is set.

+**
+** open write cursor to <table> and its indices
+** puts VALUES clause expressions onto the stack
+** write the resulting record into <table>
+** cleanup
+**
+** The three remaining templates assume the statement is of the form

+** INSERT INTO <table> SELECT ...
+**
+** If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
+** in other words if the SELECT pulls all columns from a single table
+** and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
+** if <table2> and <table1> are distinct tables but have identical
+** schemas, including all the same indices, then a special optimization
+** is invoked that copies raw records from <table2> over to <table1>.
+** See the xferOptimization() function for the implementation of this
+** template. This is the 2nd template.
+**
+** open a write cursor to <table>
+** open read cursor on <table2>
+** transfer all records in <table2> over to <table>
+** close cursors
+** foreach index on <table>
+** open a write cursor on the <table> index
+** open a read cursor on the corresponding <table2> index
+** transfer all records from the read to the write cursors
+** close cursors
+** end foreach
+**
+** The 3rd template is for when the second template does not apply
+** and the SELECT clause does not read from <table> at any time.
+** The generated code follows this template:
+**
+** EOF <- 0
+** X <- A
+** goto B
+** A: setup for the SELECT
+** loop over the rows in the SELECT
+** load values into registers R..R+n
+** yield X
+** end loop
+** cleanup after the SELECT
+** EOF <- 1
+** yield X
+** goto A
+** B: open write cursor to <table> and its indices
+** C: yield X
+** if EOF goto D
+** insert the select result into <table> from R..R+n
+** goto C
+** D: cleanup
+**
+** The 4th template is used if the insert statement takes its
+** values from a SELECT but the data is being inserted into a table
+** that is also read as part of the SELECT. In the third form,
+** we have to use a intermediate table to store the results of
+** the select. The template is like this:
+**
+** EOF <- 0
+** X <- A
+** goto B
+** A: setup for the SELECT
+** loop over the tables in the SELECT
+** load value into register R..R+n
+** yield X
+** end loop
+** cleanup after the SELECT
+** EOF <- 1
+** yield X
+** halt-error
+** B: open temp table
+** L: yield X
+** if EOF goto M
+** insert row from R..R+n into temp table
+** goto L
+** M: open write cursor to <table> and its indices

+** the address of a register containing the rowid before the update takes
+** place. isUpdate is true for UPDATEs and false for INSERTs. If isUpdate
+** is false, indicating an INSERT statement, then a non-zero rowidChng
+** indicates that the rowid was explicitly specified as part of the
+** INSERT statement. If rowidChng is false, it means that the rowid is
+** computed automatically in an insert or that the rowid value is not
+** modified by an update.
+**
+** The code generated by this routine store new index entries into

+** attached to the table.
+**
+** This routine also generates code to check constraints. NOT NULL,
+** CHECK, and UNIQUE constraints are all checked. If a constraint fails,
+** then the appropriate action is performed. There are five possible
+** actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
+**
+** Constraint type Action What Happens
+** --------------- ---------- ----------------------------------------
+** any ROLLBACK The current transaction is rolled back and
+** sqlite3_exec() returns immediately with a
+** return code of SQLITE_CONSTRAINT.
+**
+** any ABORT Back out changes from the current command
+** only (do not do a complete rollback) then
+** cause sqlite3_exec() to return immediately
+** with SQLITE_CONSTRAINT.
+**
+** any FAIL Sqlite3_exec() returns immediately with a
+** return code of SQLITE_CONSTRAINT. The
+** transaction is not rolled back and any
+** prior changes are retained.
+**
+** any IGNORE The record number and data is popped from
+** the stack and there is an immediate jump
+** to label ignoreDest.
+**
+** NOT NULL REPLACE The NULL value is replace by the default
+** value for that column. If the default value
+** is NULL, the action is the same as ABORT.
+**
+** UNIQUE REPLACE The other row that conflicts with the row
+** being inserted is removed.
+**
+** CHECK REPLACE Illegal. The results in an exception.
+**
+** Which action to take is determined by the overrideError parameter.
+** Or if overrideError==OE_Default, then the pParse->onError parameter
+** is used. Or if pParse->onError==OE_Default then the onError value
+** for the constraint is used.
+**
+** The calling routine must open a read/write cursor for pTab with

+** read/write cursors with cursor number baseCur+i for the i-th cursor.

+** Alternative compound select code generator for cases when there
+** is an ORDER BY clause.
+**
+** We assume a query of the following form:
+**
+** <selectA> <operator> <selectB> ORDER BY <orderbylist>
+**
+** <operator> is one of UNION ALL, UNION, EXCEPT, or INTERSECT. The idea
+** is to code both <selectA> and <selectB> with the ORDER BY clause as
+** co-routines. Then run the co-routines in parallel and merge the results
+** into the output. In addition to the two coroutines (called selectA and
+** selectB) there are 7 subroutines:
+**
+** outA: Move the output of the selectA coroutine into the output
+** of the compound query.
+**
+** outB: Move the output of the selectB coroutine into the output
+** of the compound query. (Only generated for UNION and
+** UNION ALL. EXCEPT and INSERTSECT never output a row that
+** appears only in B.)
+**
+** AltB: Called when there is data from both coroutines and A<B.
+**
+** AeqB: Called when there is data from both coroutines and A==B.
+**
+** AgtB: Called when there is data from both coroutines and A>B.
+**
+** EofA: Called when data is exhausted from selectA.
+**
+** EofB: Called when data is exhausted from selectB.
+**
+** The implementation of the latter five subroutines depend on which
+** <operator> is used:
+**
+**
+** UNION ALL UNION EXCEPT INTERSECT
+** ------------- ----------------- -------------- -----------------
+** AltB: outA, nextA outA, nextA outA, nextA nextA
+**
+** AeqB: outA, nextA nextA nextA outA, nextA
+**
+** AgtB: outB, nextB outB, nextB nextB nextB
+**
+** EofA: outB, nextB outB, nextB halt halt
+**
+** EofB: outA, nextA outA, nextA outA, nextA halt
+**
+** In the AltB, AeqB, and AgtB subroutines, an EOF on A following nextA
+** causes an immediate jump to EofA and an EOF on B following nextB causes
+** an immediate jump to EofB. Within EofA and EofB, and EOF on entry or
+** following nextX causes a jump to the end of the select processing.
+**
+** Duplicate removal in the UNION, EXCEPT, and INTERSECT cases is handled
+** within the output subroutine. The regPrev register set holds the previously
+** output value. A comparison is made against this value and the output
+** is skipped if the next results would be the same as the previous.
+**
+** The implementation plan is to implement the two coroutines and seven
+** subroutines first, then put the control logic at the bottom. Like this:
+**
+** goto Init
+** coA: coroutine for left query (A)
+** coB: coroutine for right query (B)
+** outA: output one row of A
+** outB: output one row of B (UNION and UNION ALL only)
+** EofA: ...
+** EofB: ...
+** AltB: ...
+** AeqB: ...
+** AgtB: ...
+** Init: initialize coroutine registers
+** yield coA
+** if eof(A) goto EofA
+** yield coB
+** if eof(B) goto EofB
+** Cmpr: Compare A, B
+** Jump AltB, AeqB, AgtB
+** End: ...
+**
+** We call AltB, AeqB, AgtB, EofA, and EofB "subroutines" but they are not
+** actually called using Gosub and they do not Return. EofA and EofB loop
+** until all data is exhausted then jump to the "end" labe. AltB, AeqB,
+** and AgtB jump to either L2 or to one of EofA or EofB.

+** This routine attempts to flatten subqueries as a performance optimization.

+**
+** To understand the concept of flattening, consider the following

+** SELECT a FROM (SELECT x+y AS a FROM t1 WHERE z<100) WHERE a>5
+**
+** The default way of implementing this query is to execute the

+** passes over the data. Furthermore, because the temporary table
+** has no indices, the WHERE clause on the outer query cannot be

+**
+** This routine attempts to rewrite queries such as the above into
+** a single flat select, like this:
+**
+** SELECT x+y AS a FROM t1 WHERE z<100 AND a>5
+**
+** The code generated for this simpification gives the same result
+** but only has to scan the data once. And because indices might
+** exist on the table t1, a complete scan of the data might be
+** avoided.
+**
+** Flattening is only attempted if all of the following are true:
+**
+** (1) The subquery and the outer query do not both use aggregates.
+**
+** (2) The subquery is not an aggregate or the outer query is not a join.
+**
+** (3) The subquery is not the right operand of a left outer join
+** (Originally ticket #306. Strengthened by ticket #3300)
+**
+** (4) The subquery is not DISTINCT.
+**
+** (**) At one point restrictions (4) and (5) defined a subset of DISTINCT
+** sub-queries that were excluded from this optimization. Restriction
+** (4) has since been expanded to exclude all DISTINCT subqueries.
+**
+** (6) The subquery does not use aggregates or the outer query is not
+** DISTINCT.
+**
+** (7) The subquery has a FROM clause. TODO: For subqueries without
+** A FROM clause, consider adding a FROM close with the special
+** table sqlite_once that consists of a single row containing a
+** single NULL.
+**
+** (8) The subquery does not use LIMIT or the outer query is not a join.
+**
+** (9) The subquery does not use LIMIT or the outer query does not use
+** aggregates.
+**
+** (10) The subquery does not use aggregates or the outer query does not
+** use LIMIT.
+**
+** (11) The subquery and the outer query do not both have ORDER BY clauses.
+**
+** (**) Not implemented. Subsumed into restriction (3). Was previously
+** a separate restriction deriving from ticket #350.
+**
+** (13) The subquery and outer query do not both use LIMIT.
+**
+** (14) The subquery does not use OFFSET.
+**
+** (15) The outer query is not part of a compound select or the
+** subquery does not have a LIMIT clause.
+** (See ticket #2339 and ticket [02a8e81d44]).
+**
+** (16) The outer query is not an aggregate or the subquery does
+** not contain ORDER BY. (Ticket #2942) This used to not matter
+** until we introduced the group_concat() function.
+**
+** (17) The sub-query is not a compound select, or it is a UNION ALL
+** compound clause made up entirely of non-aggregate queries, and
+** the parent query:
+**
+** * is not itself part of a compound select,
+** * is not an aggregate or DISTINCT query, and
+** * is not a join
+**
+** The parent and sub-query may contain WHERE clauses. Subject to
+** rules (11), (13) and (14), they may also contain ORDER BY,
+** LIMIT and OFFSET clauses. The subquery cannot use any compound
+** operator other than UNION ALL because all the other compound
+** operators have an implied DISTINCT which is disallowed by
+** restriction (4).
+**
+** Also, each component of the sub-query must return the same number
+** of result columns. This is actually a requirement for any compound
+** SELECT statement, but all the code here does is make sure that no
+** such (illegal) sub-query is flattened. The caller will detect the
+** syntax error and return a detailed message.
+**
+** (18) If the sub-query is a compound select, then all terms of the
+** ORDER by clause of the parent must be simple references to
+** columns of the sub-query.
+**
+** (19) The subquery does not use LIMIT or the outer query does not
+** have a WHERE clause.
+**
+** (20) If the sub-query is a compound select, then it must not use
+** an ORDER BY clause. Ticket #3773. We could relax this constraint
+** somewhat by saying that the terms of the ORDER BY clause must
+** appear as unmodified result columns in the outer query. But we
+** have other optimizations in mind to deal with that case.
+**
+** (21) The subquery does not use LIMIT or the outer query is not
+** DISTINCT. (See ticket [752e1646fc]).
+**
+** In this routine, the "p" parameter is a pointer to the outer query.
+** The subquery is p->pSrc->a[iFrom]. isAgg is true if the outer query
+** uses aggregates and subqueryIsAgg is true if the subquery uses aggregates.
+**
+** If flattening is not attempted, this routine is a no-op and returns 0.
+** If flattening is attempted this routine returns 1.
+**
+** All of the expression analysis must occur on both the outer query and
+** the subquery before this routine runs.

+** The query generator uses an array of instances of this structure to

+** clause subexpression is separated from the others by AND operators,
+** usually, or sometimes subexpressions separated by OR.
+**
+** All WhereTerms are collected into a single WhereClause structure.
+** The following identity holds:
+**
+** WhereTerm.pWC->a[WhereTerm.idx] == WhereTerm
+**
+** When a term is of the form:
+**
+** X <op> <expr>
+**
+** where X is a column name and <op> is one of certain operators,
+** then WhereTerm.leftCursor and WhereTerm.u.leftColumn record the
+** cursor number and column number for X. WhereTerm.eOperator records
+** the <op> using a bitmask encoding defined by WO_xxx below. The
+** use of a bitmask encoding for the operator allows us to search
+** quickly for terms that match any of several different operators.
+**
+** A WhereTerm might also be two or more subterms connected by OR:
+**
+** (t1.X <op> <expr>) OR (t1.Y <op> <expr>) OR ....
+**
+** In this second case, wtFlag as the TERM_ORINFO set and eOperator==WO_OR
+** and the WhereTerm.u.pOrInfo field points to auxiliary information that
+** is collected about the
+**
+** If a term in the WHERE clause does not match either of the two previous
+** categories, then eOperator==0. The WhereTerm.pExpr field is still set
+** to the original subexpression content and wtFlags is set up appropriately
+** but no other fields in the WhereTerm object are meaningful.
+**
+** When eOperator!=0, prereqRight and prereqAll record sets of cursor numbers,
+** but they do so indirectly. A single WhereMaskSet structure translates
+** cursor number into bits and the translated bit is stored in the prereq
+** fields. The translation is used in order to maximize the number of
+** bits that will fit in a Bitmask. The VDBE cursor numbers might be
+** spread out over the non-negative integers. For example, the cursor
+** numbers might be 3, 8, 9, 10, 20, 23, 41, and 45. The WhereMaskSet
+** translates these sparse cursor numbers into consecutive integers
+** beginning with 0 in order to make the best possible use of the available
+** bits in the Bitmask. So, in the example above, the cursor numbers
+** would be mapped into integers 0 through 7.
+**
+** The number of terms in a join is limited by the number of bits
+** in prereqRight and prereqAll. The default is 64 bits, hence SQLite

+** Analyze a term that consists of two or more OR-connected
+** subterms. So in:
+**
+** ... WHERE (a=5) AND (b=7 OR c=9 OR d=13) AND (d=13)
+** ^^^^^^^^^^^^^^^^^^^^
+**
+** This routine analyzes terms such as the middle term in the above example.
+** A WhereOrTerm object is computed and attached to the term under
+** analysis, regardless of the outcome of the analysis. Hence:
+**
+** WhereTerm.wtFlags |= TERM_ORINFO
+** WhereTerm.u.pOrInfo = a dynamically allocated WhereOrTerm object
+**
+** The term being analyzed must have two or more of OR-connected subterms.
+** A single subterm might be a set of AND-connected sub-subterms.
+** Examples of terms under analysis:
+**
+** (A) t1.x=t2.y OR t1.x=t2.z OR t1.y=15 OR t1.z=t3.a+5
+** (B) x=expr1 OR expr2=x OR x=expr3
+** (C) t1.x=t2.y OR (t1.x=t2.z AND t1.y=15)
+** (D) x=expr1 OR (y>11 AND y<22 AND z LIKE '*hello*')
+** (E) (p.a=1 AND q.b=2 AND r.c=3) OR (p.x=4 AND q.y=5 AND r.z=6)
+**
+** CASE 1:
+**
+** If all subterms are of the form T.C=expr for some single column of C and
+** a single table T (as shown in example B above) then create a new virtual
+** term that is an equivalent IN expression. In other words, if the term
+** being analyzed is:
+**
+** x = expr1 OR expr2 = x OR x = expr3
+**
+** then create a new virtual term like this:
+**
+** x IN (expr1,expr2,expr3)
+**
+** CASE 2:
+**
+** If all subterms are indexable by a single table T, then set
+**
+** WhereTerm.eOperator = WO_OR
+** WhereTerm.u.pOrInfo->indexable |= the cursor number for table T
+**
+** A subterm is "indexable" if it is of the form
+** "T.C <op> <expr>" where C is any column of table T and
+** <op> is one of "=", "<", "<=", ">", ">=", "IS NULL", or "IN".
+** A subterm is also indexable if it is an AND of two or more
+** subsubterms at least one of which is indexable. Indexable AND
+** subterms have their eOperator set to WO_AND and they have
+** u.pAndInfo set to a dynamically allocated WhereAndTerm object.
+**
+** From another point of view, "indexable" means that the subterm could
+** potentially be used with an index if an appropriate index exists.
+** This analysis does not consider whether or not the index exists; that
+** is something the bestIndex() routine will determine. This analysis
+** only looks at whether subterms appropriate for indexing exist.
+**
+** All examples A through E above all satisfy case 2. But if a term
+** also statisfies case 1 (such as B) we know that the optimizer will
+** always prefer case 1, so in that case we pretend that case 2 is not
+** satisfied.
+**
+** It might be the case that multiple tables are indexable. For example,
+** (E) above is indexable on tables P, Q, and R.
+**
+** Terms that satisfy case 2 are candidates for lookup by using
+** separate indices to find rowids for each subterm and composing
+** the union of all rowids using a RowSet object. This is similar
+** to "bitmap indices" in other database engines.
+**
+** OTHERWISE:
+**
+** If neither case 1 nor case 2 apply, then leave the eOperator set to
+** zero. This term is not useful for search.

+** This function is used to estimate the number of rows that will be visited

+** bound, a lower bound, or both. The WHERE clause terms that set the upper
+** and lower bounds are represented by pLower and pUpper respectively. For
+** example, assuming that index p is on t1(a):
+**
+** ... FROM t1 WHERE a > ? AND a < ? ...
+** |_____| |_____|
+** | |
+** pLower pUpper
+**
+** If either of the upper or lower bound is not present, then NULL is passed in
+** place of the corresponding WhereTerm.
+**
+** The nEq parameter is passed the index of the index column subject to the
+** range constraint. Or, equivalently, the number of equality constraints
+** optimized by the proposed index scan. For example, assuming index p is
+** on t1(a, b), and the SQL query is:
+**
+** ... FROM t1 WHERE a = ? AND b > ? AND b < ? ...
+**
+** then nEq should be passed the value 1 (as the range restricted column,
+** b, is the second left-most column of the index). Or, if the query is:
+**
+** ... FROM t1 WHERE a > ? AND a < ? ...
+**
+** then nEq should be passed 0.
+**
+** The returned value is an integer divisor to reduce the estimated
+** search space. A return value of 1 means that range constraints are
+** no help at all. A return value of 2 means range constraints are
+** expected to reduce the search space by half. And so forth...

+** In the absence of sqlite_stat3 ANALYZE data, each range inequality

+** Suppose the WHERE clause is this: a==5 AND b IN (1,2,3) AND c>5 AND c<10
+** The index has as many as three equality constraints, but in this
+** example, the third "c" value is an inequality. So only two
+** constraints are coded. This routine will generate code to evaluate
+** a==5 and b IN (1,2,3). The current values for a and b will be stored
+** in consecutive registers and the index of the first register is returned.
+**
+** In the example above nEq==2. But this subroutine works for any value
+** of nEq including 0. If nEq==0, this routine is nearly a no-op.
+** The only thing it does is allocate the pLevel->iMem memory cell and
+** compute the affinity string.
+**
+** This routine always allocates at least one memory cell and returns
+** the index of that memory cell. The code that
+** calls this routine will use that memory cell to store the termination
+** key value of the loop. If one or more IN operators appear, then
+** this routine allocates an additional nEq memory cells for internal
+** use.
+**
+** Before returning, *pzAff is set to point to a buffer containing a
+** copy of the column affinity string of the index allocated using
+** sqlite3DbMalloc(). Except, entries in the copy of the string associated
+** with equality constraints that use NONE affinity are set to
+** SQLITE_AFF_NONE. This is to deal with SQL such as the following:
+**
+** CREATE TABLE t1(a TEXT PRIMARY KEY, b);
+** SELECT ... FROM t1 AS t2, t1 WHERE t1.a = t2.b;
+**
+** In the example above, the index on t1(a) has TEXT affinity. But since
+** the right hand side of the equality constraint (t2.b) has NONE affinity,
+** no conversion should be attempted before using a t2.b value as part of
+** a key to search the index. Hence the first byte in the returned affinity
+** string in this example would be set to SQLITE_AFF_NONE.

+** should invoke sqlite3WhereEnd() with the return value of this function
+** in order to complete the WHERE clause processing.
+**
+** If an error occurs, this routine returns NULL.
+**
+** The basic idea is to do a nested loop, one loop for each table in
+** the FROM clause of a select. (INSERT and UPDATE statements are the
+** same as a SELECT with only a single table in the FROM clause.) For
+** example, if the SQL is this:
+**
+** SELECT * FROM t1, t2, t3 WHERE ...;
+**
+** Then the code generated is conceptually like the following:
+**
+** foreach row1 in t1 do \ Code generated
+** foreach row2 in t2 do |-- by sqlite3WhereBegin()
+** foreach row3 in t3 do /
+** ...
+** end \ Code generated
+** end |-- by sqlite3WhereEnd()
+** end /
+**
+** Note that the loops might not be nested in the order in which they
+** appear in the FROM clause if a different order is better able to make
+** use of indices. Note also that when the IN operator appears in
+** the WHERE clause, it might result in additional nested loops for
+** scanning through all values on the right-hand side of the IN.
+**
+** There are Btree cursors associated with each table. t1 uses cursor
+** number pTabList->a[0].iCursor. t2 uses the cursor pTabList->a[1].iCursor.
+** And so forth. This routine generates code to open those VDBE cursors
+** and sqlite3WhereEnd() generates the code to close them.
+**
+** The code that sqlite3WhereBegin() generates leaves the cursors named
+** in pTabList pointing at their appropriate entries. The [...] code
+** can use OP_Column and OP_Rowid opcodes on these cursors to extract
+** data from the various tables of the loop.
+**
+** If the WHERE clause is empty, the foreach loops must each scan their
+** entire tables. Thus a three-way join is an O(N^3) operation. But if
+** the tables have indices and there are terms in the WHERE clause that
+** refer to those indices, a complete table scan can be avoided and the
+** code will run much faster. Most of the work of this routine is checking
+** to see if there are indices that can be used to speed up the loop.
+**
+** Terms of the WHERE clause are also used to limit which rows actually
+** make it to the "..." in the middle of the loop. After each "foreach",
+** terms of the WHERE clause that use only terms in that loop and outer
+** loops are evaluated and if false a jump is made around all subsequent
+** inner loops (or around the "..." if the test occurs within the inner-
+** most loop)
+**
+** OUTER JOINS
+**
+** An outer join of tables t1 and t2 is conceptally coded as follows:
+**
+** foreach row1 in t1 do
+** flag = 0
+** foreach row2 in t2 do
+** start:
+** ...
+** flag = 1
+** end
+** if flag==0 then
+** move the row2 cursor to a null row
+** goto start
+** fi
+** end
+**
+** ORDER BY CLAUSE PROCESSING
+**
+** pOrderBy is a pointer to the ORDER BY clause of a SELECT statement,
+** if there is one. If there is no ORDER BY clause or if this routine
+** is called from an UPDATE or DELETE statement, then pOrderBy is NULL.
+**
+** If an index can be used so that the natural output order of the table
+** scan is correct for the ORDER BY clause, then that index is used and
+** the returned WhereInfo.nOBSat field is set to pOrderBy->nExpr. This
+** is an optimization that prevents an unnecessary sort of the result set
+** if an index appropriate for the ORDER BY clause already exists.
+**
+** If the where clause loops cannot be arranged to provide the correct
+** output order, then WhereInfo.nOBSat is 0.

+** (in which case SQLITE_CORE is not defined), or
+**
+** * The FTS3 module is being built into the core of

+*/
+
+/* The full-text index is stored in a series of b+tree (-like)
+** structures called segments which map terms to doclists. The
+** structures are like b+trees in layout, but are constructed from the
+** bottom up in optimal fashion and are not updatable. Since trees
+** are built from the bottom up, things will be described from the
+** bottom up.
+**
+**
+**** Varints ****
+** The basic unit of encoding is a variable-length integer called a
+** varint. We encode variable-length integers in little-endian order
+** using seven bits * per byte as follows:
+**
+** KEY:
+** A = 0xxxxxxx 7 bits of data and one flag bit
+** B = 1xxxxxxx 7 bits of data and one flag bit
+**
+** 7 bits - A
+** 14 bits - BA
+** 21 bits - BBA
+** and so on.
+**
+** This is similar in concept to how sqlite encodes "varints" but
+** the encoding is not the same. SQLite varints are big-endian
+** are are limited to 9 bytes in length whereas FTS3 varints are
+** little-endian and can be up to 10 bytes in length (in theory).
+**
+** Example encodings:
+**
+** 1: 0x01
+** 127: 0x7f
+** 128: 0x81 0x00
+**
+**
+**** Document lists ****
+** A doclist (document list) holds a docid-sorted list of hits for a
+** given term. Doclists hold docids and associated token positions.
+** A docid is the unique integer identifier for a single document.
+** A position is the index of a word within the document. The first
+** word of the document has a position of 0.
+**
+** FTS3 used to optionally store character offsets using a compile-time
+** option. But that functionality is no longer supported.
+**
+** A doclist is stored like this:
+**
+** array {
+** varint docid; (delta from previous doclist)
+** array { (position list for column 0)
+** varint position; (2 more than the delta from previous position)
+** }
+** array {
+** varint POS_COLUMN; (marks start of position list for new column)
+** varint column; (index of new column)
+** array {
+** varint position; (2 more than the delta from previous position)
+** }
+** }
+** varint POS_END; (marks end of positions for this document.
+** }
+**
+** Here, array { X } means zero or more occurrences of X, adjacent in
+** memory. A "position" is an index of a token in the token stream
+** generated by the tokenizer. Note that POS_END and POS_COLUMN occur
+** in the same logical place as the position element, and act as sentinals
+** ending a position list array. POS_END is 0. POS_COLUMN is 1.
+** The positions numbers are not stored literally but rather as two more
+** than the difference from the prior position, or the just the position plus
+** 2 for the first position. Example:
+**
+** label: A B C D E F G H I J K
+** value: 123 5 9 1 1 14 35 0 234 72 0
+**
+** The 123 value is the first docid. For column zero in this document
+** there are two matches at positions 3 and 10 (5-2 and 9-2+3). The 1
+** at D signals the start of a new column; the 1 at E indicates that the
+** new column is column number 1. There are two positions at 12 and 45
+** (14-2 and 35-2+12). The 0 at H indicate the end-of-document. The
+** 234 at I is the delta to next docid (357). It has one position 70
+** (72-2) and then terminates with the 0 at K.
+**
+** A "position-list" is the list of positions for multiple columns for
+** a single docid. A "column-list" is the set of positions for a single
+** column. Hence, a position-list consists of one or more column-lists,
+** a document record consists of a docid followed by a position-list and
+** a doclist consists of one or more document records.
+**
+** A bare doclist omits the position information, becoming an
+** array of varint-encoded docids.
+**
+**** Segment leaf nodes ****
+** Segment leaf nodes store terms and doclists, ordered by term. Leaf
+** nodes are written using LeafWriter, and read using LeafReader (to
+** iterate through a single leaf node's data) and LeavesReader (to
+** iterate through a segment's entire leaf layer). Leaf nodes have
+** the format:
+**
+** varint iHeight; (height from leaf level, always 0)
+** varint nTerm; (length of first term)
+** char pTerm[nTerm]; (content of first term)
+** varint nDoclist; (length of term's associated doclist)
+** char pDoclist[nDoclist]; (content of doclist)
+** array {
+** (further terms are delta-encoded)
+** varint nPrefix; (length of prefix shared with previous term)
+** varint nSuffix; (length of unshared suffix)
+** char pTermSuffix[nSuffix];(unshared suffix of next term)
+** varint nDoclist; (length of term's associated doclist)
+** char pDoclist[nDoclist]; (content of doclist)
+** }
+**
+** Here, array { X } means zero or more occurrences of X, adjacent in
+** memory.
+**
+** Leaf nodes are broken into blocks which are stored contiguously in
+** the %_segments table in sorted order. This means that when the end
+** of a node is reached, the next term is in the node with the next
+** greater node id.
+**
+** New data is spilled to a new leaf node when the current node
+** exceeds LEAF_MAX bytes (default 2048). New data which itself is
+** larger than STANDALONE_MIN (default 1024) is placed in a standalone
+** node (a leaf node with a single term and doclist). The goal of
+** these settings is to pack together groups of small doclists while
+** making it efficient to directly access large doclists. The
+** assumption is that large doclists represent terms which are more
+** likely to be query targets.
+**
+** TODO(shess) It may be useful for blocking decisions to be more
+** dynamic. For instance, it may make more sense to have a 2.5k leaf
+** node rather than splitting into 2k and .5k nodes. My intuition is
+** that this might extend through 2x or 4x the pagesize.
+**
+**
+**** Segment interior nodes ****
+** Segment interior nodes store blockids for subtree nodes and terms
+** to describe what data is stored by the each subtree. Interior
+** nodes are written using InteriorWriter, and read using
+** InteriorReader. InteriorWriters are created as needed when
+** SegmentWriter creates new leaf nodes, or when an interior node
+** itself grows too big and must be split. The format of interior
+** nodes:
+**
+** varint iHeight; (height from leaf level, always >0)
+** varint iBlockid; (block id of node's leftmost subtree)
+** optional {
+** varint nTerm; (length of first term)
+** char pTerm[nTerm]; (content of first term)
+** array {
+** (further terms are delta-encoded)
+** varint nPrefix; (length of shared prefix with previous term)
+** varint nSuffix; (length of unshared suffix)
+** char pTermSuffix[nSuffix]; (unshared suffix of next term)
+** }
+** }
+**
+** Here, optional { X } means an optional element, while array { X }
+** means zero or more occurrences of X, adjacent in memory.
+**
+** An interior node encodes n terms separating n+1 subtrees. The
+** subtree blocks are contiguous, so only the first subtree's blockid
+** is encoded. The subtree at iBlockid will contain all terms less
+** than the first term encoded (or all terms if no term is encoded).
+** Otherwise, for terms greater than or equal to pTerm[i] but less
+** than pTerm[i+1], the subtree for that term will be rooted at
+** iBlockid+i. Interior nodes only store enough term data to
+** distinguish adjacent children (if the rightmost term of the left
+** child is "something", and the leftmost term of the right child is
+** "wicked", only "w" is stored).
+**
+** New data is spilled to a new interior node at the same height when
+** the current node exceeds INTERIOR_MAX bytes (default 2048).
+** INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing
+** interior nodes and making the tree too skinny. The interior nodes
+** at a given height are naturally tracked by interior nodes at
+** height+1, and so on.
+**
+**
+**** Segment directory ****
+** The segment directory in table %_segdir stores meta-information for
+** merging and deleting segments, and also the root node of the
+** segment's tree.
+**
+** The root node is the top node of the segment's tree after encoding
+** the entire segment, restricted to ROOT_MAX bytes (default 1024).
+** This could be either a leaf node or an interior node. If the top
+** node requires more than ROOT_MAX bytes, it is flushed to %_segments
+** and a new root interior node is generated (which should always fit
+** within ROOT_MAX because it only needs space for 2 varints, the
+** height and the blockid of the previous root).
+**
+** The meta-information in the segment directory is:
+** level - segment level (see below)
+** idx - index within level
+** - (level,idx uniquely identify a segment)
+** start_block - first leaf node
+** leaves_end_block - last leaf node
+** end_block - last block (including interior nodes)
+** root - contents of root node
+**
+** If the root node is a leaf node, then start_block,
+** leaves_end_block, and end_block are all 0.
+**
+**
+**** Segment merging ****
+** To amortize update costs, segments are grouped into levels and
+** merged in batches. Each increase in level represents exponentially
+** more documents.
+**
+** New documents (actually, document updates) are tokenized and
+** written individually (using LeafWriter) to a level 0 segment, with
+** incrementing idx. When idx reaches MERGE_COUNT (default 16), all
+** level 0 segments are merged into a single level 1 segment. Level 1
+** is populated like level 0, and eventually MERGE_COUNT level 1
+** segments are merged to a single level 2 segment (representing
+** MERGE_COUNT^2 updates), and so on.
+**
+** A segment merge traverses all segments at a given level in
+** parallel, performing a straightforward sorted merge. Since segment
+** leaf nodes are written in to the %_segments table in order, this
+** merge traverses the underlying sqlite disk structures efficiently.
+** After the merge, all segment blocks from the merged level are
+** deleted.
+**
+** MERGE_COUNT controls how often we merge segments. 16 seems to be
+** somewhat of a sweet spot for insertion performance. 32 and 64 show
+** very similar performance numbers to 16 on insertion, though they're
+** a tiny bit slower (perhaps due to more overhead in merge-time
+** sorting). 8 is about 20% slower than 16, 4 about 50% slower than
+** 16, 2 about 66% slower than 16.
+**
+** At query time, high MERGE_COUNT increases the number of segments
+** which need to be scanned and merged. For instance, with 100k docs
+** inserted:
+**
+** MERGE_COUNT segments
+** 16 25
+** 8 12
+** 4 10
+** 2 6
+**
+** This appears to have only a moderate impact on queries for very
+** frequent terms (which are somewhat dominated by segment merge
+** costs), and infrequent and non-existent terms still seem to be fast
+** even with many segments.
+**
+** TODO(shess) That said, it would be nice to have a better query-side
+** argument for MERGE_COUNT of 16. Also, it is possible/likely that
+** optimizations to things like doclist merging will swing the sweet
+** spot around.
+**
+**
+**
+**** Handling of deletions and updates ****
+** Since we're using a segmented structure, with no docid-oriented
+** index into the term index, we clearly cannot simply update the term
+** index when a document is deleted or updated. For deletions, we
+** write an empty doclist (varint(docid) varint(POS_END)), for updates
+** we simply write the new doclist. Segment merges overwrite older
+** data for a particular docid with newer data, so deletes or updates
+** will eventually overtake the earlier data and knock it out. The
+** query logic likewise merges doclists so that newer data knocks out
+** older data.

+** for the phrase for the visited row:

+** 1. Deferred tokens are not taken into account. If a phrase consists

+** the db. In this case the position-list is not populated at all.
+**
+** Or, if a phrase contains one or more deferred tokens and one or
+** more non-deferred tokens, then the expression is advanced to the
+** next possible match, considering only non-deferred tokens. In other
+** words, if the phrase is "A B C", and "B" is deferred, the expression
+** is advanced to the next row that contains an instance of "A * C",
+** where "*" may match any single token. The position list in this case
+** is populated as for "A * C" before returning.
+**
+** 2. NEAR is treated as AND. If the expression is "x NEAR y", it is
+** advanced to point to the next row that matches "x AND y".
+**
+** See fts3EvalTestDeferredAndNear() for details on testing if a row is
+** really a match, taking into account deferred tokens and NEAR operators.

+
+/*
+** By default, this module parses the legacy syntax that has been
+** traditionally used by fts3. Or, if SQLITE_ENABLE_FTS3_PARENTHESIS
+** is defined, then it uses the new syntax. The differences between
+** the new and the old syntaxes are:
+**
+** a) The new syntax supports parenthesis. The old does not.
+**
+** b) The new syntax supports the AND and NOT operators. The old does not.
+**
+** c) The old syntax supports the "-" token qualifier. This is not
+** supported by the new syntax (it is replaced by the NOT operator).
+**
+** d) When using the old syntax, the OR operator has a greater precedence
+** than an implicit AND. When using the new, both implicity and explicit
+** AND operators have a higher precedence than OR.
+**
+** If compiled with SQLITE_TEST defined, then this module exports the
+** symbol "int sqlite3_fts3_enable_parentheses". Setting this variable
+** to zero causes the module to use the old syntax. If it is set to
+** non-zero the new syntax is activated. This is so both syntaxes can
+** be tested using a single build of testfixture.
+**
+** The following describes the syntax supported by the fts3 MATCH
+** operator in a similar format to that used by the lemon parser
+** generator. This module does not use actually lemon, it uses a
+** custom parser.
+**
+** query ::= andexpr (OR andexpr)*.
+**
+** andexpr ::= notexpr (AND? notexpr)*.
+**
+** notexpr ::= nearexpr (NOT nearexpr|-TOKEN)*.
+** notexpr ::= LP query RP.
+**
+** nearexpr ::= phrase (NEAR distance_opt nearexpr)*.
+**
+** distance_opt ::= .
+** distance_opt ::= / INTEGER.
+**
+** phrase ::= TOKEN.
+** phrase ::= COLUMN:TOKEN.
+** phrase ::= "TOKEN TOKEN TOKEN...".

+** Database Format of R-Tree Tables
+** --------------------------------
+**
+** The data structure for a single virtual r-tree table is stored in three
+** native SQLite tables declared as follows. In each case, the '%' character
+** in the table name is replaced with the user-supplied name of the r-tree
+** table.
+**
+** CREATE TABLE %_node(nodeno INTEGER PRIMARY KEY, data BLOB)
+** CREATE TABLE %_parent(nodeno INTEGER PRIMARY KEY, parentnode INTEGER)
+** CREATE TABLE %_rowid(rowid INTEGER PRIMARY KEY, nodeno INTEGER)
+**
+** The data for each node of the r-tree structure is stored in the %_node
+** table. For each node that is not the root node of the r-tree, there is
+** an entry in the %_parent table associating the node with its parent.
+** And for each row of data in the table, there is an entry in the %_rowid
+** table that maps from the entries rowid to the id of the node that it
+** is stored on.
+**
+** The root node of an r-tree always exists, even if the r-tree table is
+** empty. The nodeno of the root node is always 1. All other nodes in the
+** table must be the same size as the root node. The content of each node
+** is formatted as follows:
+**
+** 1. If the node is the root node (node 1), then the first 2 bytes
+** of the node contain the tree depth as a big-endian integer.
+** For non-root nodes, the first 2 bytes are left unused.
+**
+** 2. The next 2 bytes contain the number of entries currently
+** stored in the node.
+**
+** 3. The remainder of the node contains the node entries. Each entry
+** consists of a single 8-byte integer followed by an even number
+** of 4-byte coordinates. For leaf nodes the integer is the rowid
+** of a record. For internal nodes it is the node number of a
+** child page.

+** PENDING, or EXCLUSIVE lock on the file. It returns true
+** if such a lock exists and false otherwise.
+**
+** The xFileControl() method is a generic interface that allows custom
+** VFS implementations to directly control an open file using the

+** point to a structure that may contain arguments or space in which to
+** write return values. Potential uses for xFileControl() might be
+** functions to enable blocking locks with timeouts, to change the
+** locking strategy (for example to use dot-file locks), to inquire

+**
+** These integer constants are opcodes for the xFileControl method
+** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
+** interface.
+**
+** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging. This
+** opcode causes the xFileControl method to write the current state of
+** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
+** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
+** into an integer that the pArg argument points to. This capability
+** is used during testing and only needs to be supported when SQLITE_TEST
+** is defined.
+** <ul>
+** <li>[[SQLITE_FCNTL_SIZE_HINT]]
+** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
+** layer a hint of how large the database file will grow to be during the
+** current transaction. This hint is not guaranteed to be accurate but it
+** is often close. The underlying VFS might choose to preallocate database
+** file space based on this hint in order to help writes to the database
+** file run faster.
+**
+** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
+** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
+** extends and truncates the database file in chunks of a size specified
+** by the user. The fourth argument to [sqlite3_file_control()] should
+** point to an integer (type int) containing the new chunk-size to use
+** for the nominated database. Allocating database file space in large
+** chunks (say 1MB at a time), may reduce file-system fragmentation and
+** improve performance on some systems.
+**
+** <li>[[SQLITE_FCNTL_FILE_POINTER]]
+** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with a particular database
+** connection. See the [sqlite3_file_control()] documentation for
+** additional information.
+**
+** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
+** ^(The [SQLITE_FCNTL_SYNC_OMITTED] opcode is generated internally by
+** SQLite and sent to all VFSes in place of a call to the xSync method
+** when the database connection has [PRAGMA synchronous] set to OFF.)^
+** Some specialized VFSes need this signal in order to operate correctly
+** when [PRAGMA synchronous | PRAGMA synchronous=OFF] is set, but most
+** VFSes do not need this signal and should silently ignore this opcode.
+** Applications should not call [sqlite3_file_control()] with this
+** opcode as doing so may disrupt the operation of the specialized VFSes
+** that do require it.
+**
+** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
+** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
+** retry counts and intervals for certain disk I/O operations for the
+** windows [VFS] in order to provide robustness in the presence of
+** anti-virus programs. By default, the windows VFS will retry file read,
+** file write, and file delete operations up to 10 times, with a delay
+** of 25 milliseconds before the first retry and with the delay increasing
+** by an additional 25 milliseconds with each subsequent retry. This
+** opcode allows these two values (10 retries and 25 milliseconds of delay)
+** to be adjusted. The values are changed for all database connections
+** within the same process. The argument is a pointer to an array of two
+** integers where the first integer i the new retry count and the second
+** integer is the delay. If either integer is negative, then the setting
+** is not changed but instead the prior value of that setting is written
+** into the array entry, allowing the current retry settings to be
+** interrogated. The zDbName parameter is ignored.
+**
+** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
+** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
+** persistent [WAL | Write Ahead Log] setting. By default, the auxiliary
+** write ahead log and shared memory files used for transaction control
+** are automatically deleted when the latest connection to the database
+** closes. Setting persistent WAL mode causes those files to persist after
+** close. Persisting the files is useful when other processes that do not
+** have write permission on the directory containing the database file want
+** to read the database file, as the WAL and shared memory files must exist
+** in order for the database to be readable. The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
+** WAL mode. If the integer is -1, then it is overwritten with the current
+** WAL persistence setting.
+**
+** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
+** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
+** persistent "powersafe-overwrite" or "PSOW" setting. The PSOW setting
+** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
+** xDeviceCharacteristics methods. The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
+** mode. If the integer is -1, then it is overwritten with the current
+** zero-damage mode setting.
+**
+** <li>[[SQLITE_FCNTL_OVERWRITE]]
+** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
+** a write transaction to indicate that, unless it is rolled back for some
+** reason, the entire database file will be overwritten by the current
+** transaction. This is used by VACUUM operations.
+**
+** <li>[[SQLITE_FCNTL_VFSNAME]]
+** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
+** all [VFSes] in the VFS stack. The names are of all VFS shims and the
+** final bottom-level VFS are written into memory obtained from
+** [sqlite3_malloc()] and the result is stored in the char* variable
+** that the fourth parameter of [sqlite3_file_control()] points to.
+** The caller is responsible for freeing the memory when done. As with
+** all file-control actions, there is no guarantee that this will actually
+** do anything. Callers should initialize the char* variable to a NULL
+** pointer in case this file-control is not implemented. This file-control
+** is intended for diagnostic use only.
+**
+** <li>[[SQLITE_FCNTL_PRAGMA]]
+** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA]
+** file control is sent to the open [sqlite3_file] object corresponding
+** to the database file to which the pragma statement refers. ^The argument
+** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
+** pointers to strings (char**) in which the second element of the array
+** is the name of the pragma and the third element is the argument to the
+** pragma or NULL if the pragma has no argument. ^The handler for an
+** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
+** of the char** argument point to a string obtained from [sqlite3_mprintf()]
+** or the equivalent and that string will become the result of the pragma or
+** the error message if the pragma fails. ^If the
+** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal
+** [PRAGMA] processing continues. ^If the [SQLITE_FCNTL_PRAGMA]
+** file control returns [SQLITE_OK], then the parser assumes that the
+** VFS has handled the PRAGMA itself and the parser generates a no-op
+** prepared statement. ^If the [SQLITE_FCNTL_PRAGMA] file control returns
+** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
+** that the VFS encountered an error while handling the [PRAGMA] and the
+** compilation of the PRAGMA fails with an error. ^The [SQLITE_FCNTL_PRAGMA]
+** file control occurs at the beginning of pragma statement analysis and so
+** it is able to override built-in [PRAGMA] statements.
+**
+** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
+** ^The [SQLITE_FCNTL_BUSYHANDLER]
+** file-control may be invoked by SQLite on the database file handle
+** shortly after it is opened in order to provide a custom VFS with access
+** to the connections busy-handler callback. The argument is of type (void **)
+** - an array of two (void *) values. The first (void *) actually points
+** to a function of type (int (*)(void *)). In order to invoke the connections
+** busy-handler, this function should be invoked with the second (void *) in
+** the array as the only argument. If it returns non-zero, then the operation
+** should be retried. If it returns zero, the custom VFS should abandon the
+** current operation.
+**
+** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
+** ^Application can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
+** to have SQLite generate a
+** temporary filename using the same algorithm that is followed to generate
+** temporary filenames for TEMP tables and other internal uses. The
+** argument should be a char** which will be filled with the filename
+** written into memory obtained from [sqlite3_malloc()]. The caller should
+** invoke [sqlite3_free()] on the result to avoid a memory leak.
+**
+** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
+** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
+** maximum number of bytes that will be used for memory-mapped I/O.
+** The argument is a pointer to a value of type sqlite3_int64 that
+** is an advisory maximum number of bytes in the file to memory map. The
+** pointer is overwritten with the old value. The limit is not changed if
+** the value originally pointed to is negative, and so the current limit
+** can be queried by passing in a pointer to a negative number. This
+** file-control is used internally to implement [PRAGMA mmap_size].

+*/
+typedef struct sqlite3_mutex sqlite3_mutex;
+
+/*
+** CAPI3REF: OS Interface Object
+**
+** An instance of the sqlite3_vfs object defines the interface between
+** the SQLite core and the underlying operating system. The "vfs"
+** in the name of the object stands for "virtual file system". See
+** the [VFS | VFS documentation] for further information.
+**
+** The value of the iVersion field is initially 1 but may be larger in
+** future versions of SQLite. Additional fields may be appended to this
+** object when the iVersion value is increased. Note that the structure
+** of the sqlite3_vfs object changes in the transaction between
+** SQLite version 3.5.9 and 3.6.0 and yet the iVersion field was not
+** modified.
+**
+** The szOsFile field is the size of the subclassed [sqlite3_file]
+** structure used by this VFS. mxPathname is the maximum length of
+** a pathname in this VFS.
+**
+** Registered sqlite3_vfs objects are kept on a linked list formed by
+** the pNext pointer. The [sqlite3_vfs_register()]
+** and [sqlite3_vfs_unregister()] interfaces manage this list
+** in a thread-safe way. The [sqlite3_vfs_find()] interface
+** searches the list. Neither the application code nor the VFS
+** implementation should use the pNext pointer.
+**
+** The pNext field is the only field in the sqlite3_vfs
+** structure that SQLite will ever modify. SQLite will only access
+** or modify this field while holding a particular static mutex.
+** The application should never modify anything within the sqlite3_vfs
+** object once the object has been registered.
+**
+** The zName field holds the name of the VFS module. The name must
+** be unique across all VFS modules.
+**
+** [[sqlite3_vfs.xOpen]]
+** ^SQLite guarantees that the zFilename parameter to xOpen
+** is either a NULL pointer or string obtained
+** from xFullPathname() with an optional suffix added.
+** ^If a suffix is added to the zFilename parameter, it will
+** consist of a single "-" character followed by no more than
+** 11 alphanumeric and/or "-" characters.
+** ^SQLite further guarantees that
+** the string will be valid and unchanged until xClose() is
+** called. Because of the previous sentence,
+** the [sqlite3_file] can safely store a pointer to the
+** filename if it needs to remember the filename for some reason.
+** If the zFilename parameter to xOpen is a NULL pointer then xOpen
+** must invent its own temporary name for the file. ^Whenever the
+** xFilename parameter is NULL it will also be the case that the
+** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
+**
+** The flags argument to xOpen() includes all bits set in
+** the flags argument to [sqlite3_open_v2()]. Or if [sqlite3_open()]
+** or [sqlite3_open16()] is used, then flags includes at least
+** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
+** If xOpen() opens a file read-only then it sets *pOutFlags to
+** include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be set.
+**
+** ^(SQLite will also add one of the following flags to the xOpen()
+** call, depending on the object being opened:
+**
+** <ul>
+** <li> [SQLITE_OPEN_MAIN_DB]
+** <li> [SQLITE_OPEN_MAIN_JOURNAL]
+** <li> [SQLITE_OPEN_TEMP_DB]
+** <li> [SQLITE_OPEN_TEMP_JOURNAL]
+** <li> [SQLITE_OPEN_TRANSIENT_DB]
+** <li> [SQLITE_OPEN_SUBJOURNAL]
+** <li> [SQLITE_OPEN_MASTER_JOURNAL]
+** <li> [SQLITE_OPEN_WAL]
+** </ul>)^
+**
+** The file I/O implementation can use the object type flags to
+** change the way it deals with files. For example, an application
+** that does not care about crash recovery or rollback might make
+** the open of a journal file a no-op. Writes to this journal would
+** also be no-ops, and any attempt to read the journal would return
+** SQLITE_IOERR. Or the implementation might recognize that a database
+** file will be doing page-aligned sector reads and writes in a random
+** order and set up its I/O subsystem accordingly.
+**
+** SQLite might also add one of the following flags to the xOpen method:
+**
+** <ul>
+** <li> [SQLITE_OPEN_DELETEONCLOSE]
+** <li> [SQLITE_OPEN_EXCLUSIVE]
+** </ul>
+**
+** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
+** deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE]
+** will be set for TEMP databases and their journals, transient
+** databases, and subjournals.
+**
+** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
+** with the [SQLITE_OPEN_CREATE] flag, which are both directly
+** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
+** API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
+** SQLITE_OPEN_CREATE, is used to indicate that file should always
+** be created, and that it is an error if it already exists.
+** It is <i>not</i> used to indicate the file should be opened
+** for exclusive access.
+**
+** ^At least szOsFile bytes of memory are allocated by SQLite
+** to hold the [sqlite3_file] structure passed as the third
+** argument to xOpen. The xOpen method does not have to
+** allocate the structure; it should just fill it in. Note that
+** the xOpen method must set the sqlite3_file.pMethods to either
+** a valid [sqlite3_io_methods] object or to NULL. xOpen must do
+** this even if the open fails. SQLite expects that the sqlite3_file.pMethods
+** element will be valid after xOpen returns regardless of the success
+** or failure of the xOpen call.
+**
+** [[sqlite3_vfs.xAccess]]
+** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
+** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
+** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
+** to test whether a file is at least readable. The file can be a
+** directory.
+**
+** ^SQLite will always allocate at least mxPathname+1 bytes for the
+** output buffer xFullPathname. The exact size of the output buffer
+** is also passed as a parameter to both methods. If the output buffer
+** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
+** handled as a fatal error by SQLite, vfs implementations should endeavor
+** to prevent this by setting mxPathname to a sufficiently large value.
+**
+** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
+** interfaces are not strictly a part of the filesystem, but they are
+** included in the VFS structure for completeness.
+** The xRandomness() function attempts to return nBytes bytes
+** of good-quality randomness into zOut. The return value is
+** the actual number of bytes of randomness obtained.
+** The xSleep() method causes the calling thread to sleep for at
+** least the number of microseconds given. ^The xCurrentTime()
+** method returns a Julian Day Number for the current date and time as
+** a floating point value.
+** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
+** Day Number multiplied by 86400000 (the number of milliseconds in
+** a 24-hour day).
+** ^SQLite will use the xCurrentTimeInt64() method to get the current
+** date and time if that method is available (if iVersion is 2 or
+** greater and the function pointer is not NULL) and will fall back
+** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
+**
+** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
+** are not used by the SQLite core. These optional interfaces are provided
+** by some VFSes to facilitate testing of the VFS code. By overriding
+** system calls with functions under its control, a test program can
+** simulate faults and error conditions that would otherwise be difficult
+** or impossible to induce. The set of system calls that can be overridden
+** varies from one VFS to another, and from one version of the same VFS to the
+** next. Applications that use these interfaces must be prepared for any
+** or all of these interfaces to be NULL or for their behavior to change
+** from one release to the next. Applications must not attempt to access
+** any of these methods if the iVersion of the VFS is less than 3.

+**
+** Among other things, ^sqlite3_initialize() will invoke

+** ^If for some reason, sqlite3_initialize() is unable to initialize

+** as a mutex) it returns an [error code] other than [SQLITE_OK].
+**
+** ^The sqlite3_initialize() routine is called internally by many other
+** SQLite interfaces so that an application usually does not need to
+** invoke sqlite3_initialize() directly. For example, [sqlite3_open()]
+** calls sqlite3_initialize() so the SQLite library will be automatically

+** prior to using any other SQLite interface. For maximum portability,
+** it is recommended that applications always invoke sqlite3_initialize()
+** directly prior to using any other SQLite interface. Future releases
+** of SQLite may require this. In other words, the behavior exhibited
+** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
+** default behavior in some future release of SQLite.
+**
+** The sqlite3_os_init() routine does operating-system specific

+** The xRoundup method returns what would be the allocated size of
+** a memory allocation given a particular requested size. Most memory
+** allocators round up memory allocations at least to the next multiple
+** of 8. Some allocators round up to a larger multiple or to a power of 2.
+** Every memory allocation request coming in through [sqlite3_malloc()]
+** or [sqlite3_realloc()] first calls xRoundup. If xRoundup returns 0,
+** that causes the corresponding memory allocation to fail.
+**
+** The xInit method initializes the memory allocator. (For example,
+** it might allocate any require mutexes or initialize internal data
+** structures. The xShutdown method is invoked (indirectly) by
+** [sqlite3_shutdown()] and should deallocate any resources acquired
+** by xInit. The pAppData pointer is used as the only parameter to
+** xInit and xShutdown.
+**
+** SQLite holds the [SQLITE_MUTEX_STATIC_MASTER] mutex when it invokes
+** the xInit method, so the xInit method need not be threadsafe. The

+** holds the [SQLITE_MUTEX_STATIC_MEM] mutex as long as the

+** it is by default) and so the methods are automatically serialized.
+** However, if [SQLITE_CONFIG_MEMSTATUS] is disabled, then the other
+** methods must be threadsafe or else make their own arrangements for
+** serialization.

+** CAPI3REF: Convenience Routines For Running Queries
+**
+** This is a legacy interface that is preserved for backwards compatibility.
+** Use of this interface is not recommended.
+**
+** Definition: A <b>result table</b> is memory data structure created by the
+** [sqlite3_get_table()] interface. A result table records the
+** complete query results from one or more queries.
+**
+** The table conceptually has a number of rows and columns. But
+** these numbers are not part of the result table itself. These
+** numbers are obtained separately. Let N be the number of rows
+** and M be the number of columns.
+**
+** A result table is an array of pointers to zero-terminated UTF-8 strings.
+** There are (N+1)*M elements in the array. The first M pointers point
+** to zero-terminated strings that contain the names of the columns.
+** The remaining entries all point to query results. NULL values result
+** in NULL pointers. All other values are in their UTF-8 zero-terminated
+** string representation as returned by [sqlite3_column_text()].
+**
+** A result table might consist of one or more memory allocations.
+** It is not safe to pass a result table directly to [sqlite3_free()].
+** A result table should be deallocated using [sqlite3_free_table()].
+**
+** ^(As an example of the result table format, suppose a query result
+** is as follows:
+**
+** <blockquote><pre>
+** Name | Age
+** -----------------------
+** Alice | 43
+** Bob | 28
+** Cindy | 21
+** </pre></blockquote>
+**
+** There are two column (M==2) and three rows (N==3). Thus the
+** result table has 8 entries. Suppose the result table is stored
+** in an array names azResult. Then azResult holds this content:
+**
+** <blockquote><pre>
+** azResult[0] = "Name";
+** azResult[1] = "Age";
+** azResult[2] = "Alice";
+** azResult[3] = "43";
+** azResult[4] = "Bob";
+** azResult[5] = "28";
+** azResult[6] = "Cindy";
+** azResult[7] = "21";
+** </pre></blockquote>)^
+**
+** ^The sqlite3_get_table() function evaluates one or more
+** semicolon-separated SQL statements in the zero-terminated UTF-8
+** string of its 2nd parameter and returns a result table to the
+** pointer given in its 3rd parameter.
+**
+** After the application has finished with the result from sqlite3_get_table(),
+** it must pass the result table pointer to sqlite3_free_table() in order to
+** release the memory that was malloced. Because of the way the
+** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
+** function must not try to call [sqlite3_free()] directly. Only
+** [sqlite3_free_table()] is able to release the memory properly and safely.
+**
+** The sqlite3_get_table() interface is implemented as a wrapper around

+** NULL pointer if [sqlite3_malloc()] is unable to allocate enough
+** memory to hold the resulting string.
+**
+** ^(The sqlite3_snprintf() routine is similar to "snprintf()" from
+** the standard C library. The result is written into the
+** buffer supplied as the second parameter whose size is given by
+** the first parameter. Note that the order of the
+** first two parameters is reversed from snprintf().)^ This is an
+** historical accident that cannot be fixed without breaking
+** backwards compatibility. ^(Note also that sqlite3_snprintf()
+** returns a pointer to its buffer instead of the number of
+** characters actually written into the buffer.)^ We admit that
+** the number of characters written would be a more useful return
+** value but we cannot change the implementation of sqlite3_snprintf()
+** now without breaking compatibility.
+**
+** ^As long as the buffer size is greater than zero, sqlite3_snprintf()
+** guarantees that the buffer is always zero-terminated. ^The first
+** parameter "n" is the total size of the buffer, including space for
+** the zero terminator. So the longest string that can be completely
+** written will be n-1 characters.
+**
+** ^The sqlite3_vsnprintf() routine is a varargs version of sqlite3_snprintf().
+**
+** These routines all implement some additional formatting
+** options that are useful for constructing SQL statements.
+** All of the usual printf() formatting options apply. In addition, there
+** is are "%q", "%Q", and "%z" options.
+**
+** ^(The %q option works like %s in that it substitutes a nul-terminated
+** string from the argument list. But %q also doubles every '\'' character.
+** %q is designed for use inside a string literal.)^ By doubling each '\''
+** character it escapes that character and allows it to be inserted into
+** the string.
+**
+** For example, assume the string variable zText contains text as follows:
+**
+** <blockquote><pre>
+** char *zText = "It's a happy day!";
+** </pre></blockquote>
+**
+** One can use this text in an SQL statement as follows:
+**
+** <blockquote><pre>
+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
+** sqlite3_exec(db, zSQL, 0, 0, 0);
+** sqlite3_free(zSQL);
+** </pre></blockquote>
+**
+** Because the %q format string is used, the '\'' character in zText
+** is escaped and the SQL generated is as follows:
+**
+** <blockquote><pre>
+** INSERT INTO table1 VALUES('It''s a happy day!')
+** </pre></blockquote>
+**
+** This is correct. Had we used %s instead of %q, the generated SQL
+** would have looked like this:
+**
+** <blockquote><pre>
+** INSERT INTO table1 VALUES('It's a happy day!');
+** </pre></blockquote>
+**
+** This second example is an SQL syntax error. As a general rule you should
+** always use %q instead of %s when inserting text into a string literal.
+**
+** ^(The %Q option works like %q except it also adds single quotes around
+** the outside of the total string. Additionally, if the parameter in the
+** argument list is a NULL pointer, %Q substitutes the text "NULL" (without
+** single quotes).)^ So, for example, one could say:
+**
+** <blockquote><pre>
+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText);
+** sqlite3_exec(db, zSQL, 0, 0, 0);
+** sqlite3_free(zSQL);
+** </pre></blockquote>
+**
+** The code above will render a correct SQL statement in the zSQL
+** variable even if the zText variable is a NULL pointer.
+**
+** ^(The "%z" formatting option works like "%s" but with the
+** addition that after the string has been read and copied into
+** the result, [sqlite3_free()] is called on the input string.)^

+** [SQLITE_OPEN_READONLY | SQLITE_OPEN_* bits]
+** then the behavior is undefined.
+**
+** ^If the [SQLITE_OPEN_NOMUTEX] flag is set, then the database connection
+** opens in the multi-thread [threading mode] as long as the single-thread
+** mode has not been set at compile-time or start-time. ^If the
+** [SQLITE_OPEN_FULLMUTEX] flag is set then the database connection opens
+** in the serialized [threading mode] unless single-thread was
+** previously selected at compile-time or start-time.
+** ^The [SQLITE_OPEN_SHAREDCACHE] flag causes the database connection to be
+** eligible to use [shared cache mode], regardless of whether or not shared
+** cache is enabled using [sqlite3_enable_shared_cache()]. ^The
+** [SQLITE_OPEN_PRIVATECACHE] flag causes the database connection to not

+**
+** ^The fourth parameter to sqlite3_open_v2() is the name of the
+** [sqlite3_vfs] object that defines the operating system interface that

+** a NULL pointer then the default [sqlite3_vfs] object is used.
+**
+** ^If the filename is ":memory:", then a private, temporary in-memory database
+** is created for the connection. ^This in-memory database will vanish when
+** the database connection is closed. Future versions of SQLite might
+** make use of additional special filenames that begin with the ":" character.
+** It is recommended that when a database filename actually does begin with
+** a ":" character you should prefix the filename with a pathname such as
+** "./" to avoid ambiguity.
+**
+** ^If the filename is an empty string, then a private, temporary
+** on-disk database will be created. ^This private database will be
+** automatically deleted as soon as the database connection is closed.
+**
+** [[URI filenames in sqlite3_open()]] <h3>URI Filenames</h3>
+**
+** ^If [URI filename] interpretation is enabled, and the filename argument
+** begins with "file:", then the filename is interpreted as a URI. ^URI
+** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
+** set in the fourth argument to sqlite3_open_v2(), or if it has
+** been enabled globally using the [SQLITE_CONFIG_URI] option with the
+** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
+** As of SQLite version 3.7.7, URI filename interpretation is turned off
+** by default, but future releases of SQLite might enable URI filename
+** interpretation by default. See "[URI filenames]" for additional
+** information.
+**
+** URI filenames are parsed according to RFC 3986. ^If the URI contains an
+** authority, then it must be either an empty string or the string
+** "localhost". ^If the authority is not an empty string or "localhost", an
+** error is returned to the caller. ^The fragment component of a URI, if
+** present, is ignored.
+**
+** ^SQLite uses the path component of the URI as the name of the disk file
+** which contains the database. ^If the path begins with a '/' character,
+** then it is interpreted as an absolute path. ^If the path does not begin
+** with a '/' (meaning that the authority section is omitted from the URI)
+** then the path is interpreted as a relative path.
+** ^On windows, the first component of an absolute path
+** is a drive specification (e.g. "C:").
+**
+** [[core URI query parameters]]
+** The query component of a URI may contain parameters that are interpreted
+** either by SQLite itself, or by a [VFS | custom VFS implementation].
+** SQLite interprets the following three query parameters:
+**
+** <ul>
+** <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
+** a VFS object that provides the operating system interface that should
+** be used to access the database file on disk. ^If this option is set to
+** an empty string the default VFS object is used. ^Specifying an unknown
+** VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
+** present, then the VFS specified by the option takes precedence over
+** the value passed as the fourth parameter to sqlite3_open_v2().
+**
+** <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw",
+** "rwc", or "memory". Attempting to set it to any other value is
+** an error)^.
+** ^If "ro" is specified, then the database is opened for read-only
+** access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the
+** third argument to sqlite3_open_v2(). ^If the mode option is set to
+** "rw", then the database is opened for read-write (but not create)
+** access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had
+** been set. ^Value "rwc" is equivalent to setting both
+** SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE. ^If the mode option is
+** set to "memory" then a pure [in-memory database] that never reads
+** or writes from disk is used. ^It is an error to specify a value for
+** the mode parameter that is less restrictive than that specified by
+** the flags passed in the third parameter to sqlite3_open_v2().
+**
+** <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
+** "private". ^Setting it to "shared" is equivalent to setting the
+** SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
+** sqlite3_open_v2(). ^Setting the cache parameter to "private" is
+** equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
+** ^If sqlite3_open_v2() is used and the "cache" parameter is present in
+** a URI filename, its value overrides any behavior requested by setting
+** SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
+** </ul>
+**
+** ^Specifying an unknown parameter in the query component of a URI is not an
+** error. Future versions of SQLite might understand additional query
+** parameters. See "[query parameters with special meaning to SQLite]" for
+** additional information.

+** CAPI3REF: Compiling An SQL Statement
+** KEYWORDS: {SQL statement compiler}
+**
+** To execute an SQL query, it must first be compiled into a byte-code
+** program using one of these routines.
+**
+** The first argument, "db", is a [database connection] obtained from a
+** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
+** [sqlite3_open16()]. The database connection must not have been closed.
+**
+** The second argument, "zSql", is the statement to be compiled, encoded
+** as either UTF-8 or UTF-16. The sqlite3_prepare() and sqlite3_prepare_v2()
+** interfaces use UTF-8, and sqlite3_prepare16() and sqlite3_prepare16_v2()
+** use UTF-16.
+**
+** ^If the nByte argument is less than zero, then zSql is read up to the
+** first zero terminator. ^If nByte is non-negative, then it is the maximum
+** number of bytes read from zSql. ^When nByte is non-negative, the
+** zSql string ends at either the first '\000' or '\u0000' character or
+** the nByte-th byte, whichever comes first. If the caller knows
+** that the supplied string is nul-terminated, then there is a small
+** performance advantage to be gained by passing an nByte parameter that
+** is equal to the number of bytes in the input string <i>including</i>
+** the nul-terminator bytes as this saves SQLite from having to
+** make a copy of the input string.
+**
+** ^If pzTail is not NULL then *pzTail is made to point to the first byte
+** past the end of the first SQL statement in zSql. These routines only
+** compile the first statement in zSql, so *pzTail is left pointing to
+** what remains uncompiled.
+**
+** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
+** executed using [sqlite3_step()]. ^If there is an error, *ppStmt is set
+** to NULL. ^If the input text contains no SQL (if the input is an empty
+** string or a comment) then *ppStmt is set to NULL.
+** The calling procedure is responsible for deleting the compiled
+** SQL statement using [sqlite3_finalize()] after it has finished with it.
+** ppStmt may not be NULL.
+**
+** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
+** otherwise an [error code] is returned.
+**
+** The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are
+** recommended for all new programs. The two older interfaces are retained
+** for backwards compatibility, but their use is discouraged.
+** ^In the "v2" interfaces, the prepared statement
+** that is returned (the [sqlite3_stmt] object) contains a copy of the
+** original SQL text. This causes the [sqlite3_step()] interface to
+** behave differently in three ways:
+**
+** <ol>
+** <li>
+** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
+** always used to do, [sqlite3_step()] will automatically recompile the SQL
+** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
+** retries will occur before sqlite3_step() gives up and returns an error.
+** </li>
+**
+** <li>
+** ^When an error occurs, [sqlite3_step()] will return one of the detailed
+** [error codes] or [extended error codes]. ^The legacy behavior was that
+** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
+** and the application would have to make a second call to [sqlite3_reset()]
+** in order to find the underlying cause of the problem. With the "v2" prepare
+** interfaces, the underlying reason for the error is returned immediately.
+** </li>
+**
+** <li>
+** ^If the specific value bound to [parameter | host parameter] in the
+** WHERE clause might influence the choice of query plan for a statement,
+** then the statement will be automatically recompiled, as if there had been
+** a schema change, on the first [sqlite3_step()] call following any change
+** to the [sqlite3_bind_text | bindings] of that [parameter].
+** ^The specific value of WHERE-clause [parameter] might influence the
+** choice of query plan if the parameter is the left-hand side of a [LIKE]
+** or [GLOB] operator or if the parameter is compared to an indexed column
+** and the [SQLITE_ENABLE_STAT3] compile-time option is enabled.

+** ^The third argument is the value to bind to the parameter.

+** interfaces [sqlite3_prepare()] or [sqlite3_prepare16()], this function
+** must be called one or more times to evaluate the statement.
+**
+** The details of the behavior of the sqlite3_step() interface depend
+** on whether the statement was prepared using the newer "v2" interface
+** [sqlite3_prepare_v2()] and [sqlite3_prepare16_v2()] or the older legacy
+** interface [sqlite3_prepare()] and [sqlite3_prepare16()]. The use of the
+** new "v2" interface is recommended for new applications but the legacy
+** interface will continue to be supported.
+**
+** ^In the legacy interface, the return value will be either [SQLITE_BUSY],
+** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
+** ^With the "v2" interface, any of the other [result codes] or
+** [extended result codes] might be returned as well.
+**
+** ^[SQLITE_BUSY] means that the database engine was unable to acquire the
+** database locks it needs to do its job. ^If the statement is a [COMMIT]
+** or occurs outside of an explicit transaction, then you can retry the
+** statement. If the statement is not a [COMMIT] and occurs within an
+** explicit transaction then you should rollback the transaction before
+** continuing.
+**
+** ^[SQLITE_DONE] means that the statement has finished executing
+** successfully. sqlite3_step() should not be called again on this virtual
+** machine without first calling [sqlite3_reset()] to reset the virtual
+** machine back to its initial state.
+**
+** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
+** is returned each time a new row of data is ready for processing by the
+** caller. The values may be accessed using the [column access functions].
+** sqlite3_step() is called again to retrieve the next row of data.
+**
+** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
+** violation) has occurred. sqlite3_step() should not be called again on
+** the VM. More information may be found by calling [sqlite3_errmsg()].
+** ^With the legacy interface, a more specific error code (for example,
+** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
+** can be obtained by calling [sqlite3_reset()] on the
+** [prepared statement]. ^In the "v2" interface,
+** the more specific error code is returned directly by sqlite3_step().
+**
+** [SQLITE_MISUSE] means that the this routine was called inappropriately.
+** Perhaps it was called on a [prepared statement] that has
+** already been [sqlite3_finalize | finalized] or on one that had
+** previously returned [SQLITE_ERROR] or [SQLITE_DONE]. Or it could
+** be the case that the same database connection is being used by two or
+** more threads at the same moment in time.
+**
+** For all versions of SQLite up to and including 3.6.23.1, a call to
+** [sqlite3_reset()] was required after sqlite3_step() returned anything
+** other than [SQLITE_ROW] before any subsequent invocation of
+** sqlite3_step(). Failure to reset the prepared statement using
+** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
+** sqlite3_step(). But after version 3.6.23.1, sqlite3_step() began
+** calling [sqlite3_reset()] automatically in this circumstance rather
+** than returning [SQLITE_MISUSE]. This is not considered a compatibility
+** break because any application that ever receives an SQLITE_MISUSE error
+** is broken by definition. The [SQLITE_OMIT_AUTORESET] compile-time option
+** can be used to restore the legacy behavior.
+**
+** <b>Goofy Interface Alert:</b> In the legacy interface, the sqlite3_step()
+** API always returns a generic error code, [SQLITE_ERROR], following any
+** error other than [SQLITE_BUSY] and [SQLITE_MISUSE]. You must call
+** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
+** specific [error codes] that better describes the error.
+** We admit that this is a goofy design. The problem has been fixed
+** with the "v2" interface. If you prepare all of your SQL statements
+** using either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] instead
+** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()] interfaces,
+** then the more specific [error codes] are returned directly
+** by sqlite3_step(). The use of the "v2" interface is recommended.

+** The table above makes reference to standard C library functions atoi()
+** and atof(). SQLite does not really use these functions. It has its
+** own equivalent internal routines. The atoi() and atof() names are
+** used in the table for brevity and because they are familiar to most
+** C programmers.
+**
+** Note that when type conversions occur, pointers returned by prior
+** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
+** sqlite3_column_text16() may be invalidated.
+** Type conversions and pointer invalidations might occur
+** in the following cases:
+**
+** <ul>
+** <li> The initial content is a BLOB and sqlite3_column_text() or
+** sqlite3_column_text16() is called. A zero-terminator might
+** need to be added to the string.</li>
+** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
+** sqlite3_column_text16() is called. The content must be converted
+** to UTF-16.</li>
+** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
+** sqlite3_column_text() is called. The content must be converted
+** to UTF-8.</li>
+** </ul>
+**
+** ^Conversions between UTF-16be and UTF-16le are always done in place and do
+** not invalidate a prior pointer, though of course the content of the buffer
+** that the prior pointer references will have been modified. Other kinds
+** of conversion are done in place when it is possible, but sometimes they
+** are not possible and in those cases prior pointers are invalidated.
+**
+** The safest and easiest to remember policy is to invoke these routines
+** in one of the following ways:
+**
+** <ul>
+** <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
+** <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
+** <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
+** </ul>
+**
+** In other words, you should call sqlite3_column_text(),
+** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
+** into the desired format, then invoke sqlite3_column_bytes() or
+** sqlite3_column_bytes16() to find the size of the result. Do not mix calls
+** to sqlite3_column_text() or sqlite3_column_blob() with calls to
+** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
+** with calls to sqlite3_column_bytes().
+**
+** ^The pointers returned are valid until a type conversion occurs as

+** UTF-16 little endian, or UTF-16 big endian, respectively.
+** ^SQLite takes the text result from the application from

+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is non-negative, then as many bytes (not characters) of the text
+** pointed to by the 2nd parameter are taken as the application-defined

+** in the string at a byte offset that is less than the value of the 3rd

+** finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces or to

+** a number less than 250. SQLite will use the
+** extra szExtra bytes on each page to store metadata about the underlying
+** database page on disk. The value passed into szExtra depends
+** on the SQLite version, the target platform, and how SQLite was compiled.
+** ^The third argument to xCreate(), bPurgeable, is true if the cache being
+** created will be used to cache database pages of a file stored on disk, or
+** false if it is used for an in-memory database. The cache implementation
+** does not have to do anything special based with the value of bPurgeable;
+** it is purely advisory. ^On a cache where bPurgeable is false, SQLite will
+** never invoke xUnpin() except to deliberately delete a page.
+** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
+** false will always have the "discard" flag set to true.
+** ^Hence, a cache created with bPurgeable false will
+** never contain any unpinned pages.
+**
+** [[the xCachesize() page cache method]]
+** ^(The xCachesize() method may be called at any time by SQLite to set the
+** suggested maximum cache-size (number of pages stored by) the cache
+** instance passed as the first argument. This is the value configured using
+** the SQLite "[PRAGMA cache_size]" command.)^ As with the bPurgeable
+** parameter, the implementation is not required to do anything with this
+** value; it is advisory only.
+**
+** [[the xPagecount() page cache methods]]
+** The xPagecount() method must return the number of pages currently
+** stored in the cache, both pinned and unpinned.
+**
+** [[the xFetch() page cache methods]]
+** The xFetch() method locates a page in the cache and returns a pointer to
+** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
+** The pBuf element of the returned sqlite3_pcache_page object will be a
+** pointer to a buffer of szPage bytes used to store the content of a
+** single database page. The pExtra element of sqlite3_pcache_page will be
+** a pointer to the szExtra bytes of extra storage that SQLite has requested
+** for each entry in the page cache.
+**
+** The page to be fetched is determined by the key. ^The minimum key value
+** is 1. After it has been retrieved using xFetch, the page is considered
+** to be "pinned".
+**
+** If the requested page is already in the page cache, then the page cache
+** implementation must return a pointer to the page buffer with its content
+** intact. If the requested page is not already in the cache, then the
+** cache implementation should use the value of the createFlag
+** parameter to help it determined what action to take:
+**
+** <table border=1 width=85% align=center>
+** <tr><th> createFlag <th> Behavior when page is not already in cache
+** <tr><td> 0 <td> Do not allocate a new page. Return NULL.
+** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
+** Otherwise return NULL.
+** <tr><td> 2 <td> Make every effort to allocate a new page. Only return
+** NULL if allocating a new page is effectively impossible.
+** </table>
+**
+** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1. SQLite
+** will only use a createFlag of 2 after a prior call with a createFlag of 1
+** failed.)^ In between the to xFetch() calls, SQLite may
+** attempt to unpin one or more cache pages by spilling the content of
+** pinned pages to disk and synching the operating system disk cache.
+**
+** [[the xUnpin() page cache method]]
+** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
+** as its second argument. If the third parameter, discard, is non-zero,
+** then the page must be evicted from the cache.
+** ^If the discard parameter is
+** zero, then the page may be discarded or retained at the discretion of
+** page cache implementation. ^The page cache implementation
+** may choose to evict unpinned pages at any time.
+**
+** The cache must not perform any reference counting. A single
+** call to xUnpin() unpins the page regardless of the number of prior calls
+** to xFetch().
+**
+** [[the xRekey() page cache methods]]
+** The xRekey() method is used to change the key value associated with the
+** page passed as the second argument. If the cache
+** previously contains an entry associated with newKey, it must be
+** discarded. ^Any prior cache entry associated with newKey is guaranteed not
+** to be pinned.
+**
+** When SQLite calls the xTruncate() method, the cache must discard all
+** existing cache entries with page numbers (keys) greater than or equal
+** to the value of the iLimit parameter passed to xTruncate(). If any
+** of these pages are pinned, they are implicitly unpinned, meaning that
+** they can be safely discarded.
+**
+** [[the xDestroy() page cache method]]
+** ^The xDestroy() method is used to delete a cache allocated by xCreate().
+** All resources associated with the specified cache should be freed. ^After
+** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
+** handle invalid, and will not use it with any other sqlite3_pcache_methods2
+** functions.
+**
+** [[the xShrink() page cache method]]
+** ^SQLite invokes the xShrink() method when it wants the page cache to
+** free up as much of heap memory as possible. The page cache implementation
+** is not obligated to free any memory, but well-behaved implementations should
+** do their best.

+** individual tables within the shared-cache cannot be obtained. See
+** [SQLite Shared-Cache Mode] for a description of shared-cache locking.
+** ^This API may be used to register a callback that SQLite will invoke
+** when the connection currently holding the required lock relinquishes it.
+** ^This API is only available if the library was compiled with the
+** [SQLITE_ENABLE_UNLOCK_NOTIFY] C-preprocessor symbol defined.
+**
+** See Also: [Using the SQLite Unlock Notification Feature].
+**
+** ^Shared-cache locks are released when a database connection concludes
+** its current transaction, either by committing it or rolling it back.
+**
+** ^When a connection (known as the blocked connection) fails to obtain a
+** shared-cache lock and SQLITE_LOCKED is returned to the caller, the
+** identity of the database connection (the blocking connection) that
+** has locked the required resource is stored internally. ^After an
+** application receives an SQLITE_LOCKED error, it may call the
+** sqlite3_unlock_notify() method with the blocked connection handle as
+** the first argument to register for a callback that will be invoked
+** when the blocking connections current transaction is concluded. ^The
+** callback is invoked from within the [sqlite3_step] or [sqlite3_close]
+** call that concludes the blocking connections transaction.
+**
+** ^(If sqlite3_unlock_notify() is called in a multi-threaded application,
+** there is a chance that the blocking connection will have already
+** concluded its transaction by the time sqlite3_unlock_notify() is invoked.
+** If this happens, then the specified callback is invoked immediately,
+** from within the call to sqlite3_unlock_notify().)^
+**
+** ^If the blocked connection is attempting to obtain a write-lock on a
+** shared-cache table, and more than one other connection currently holds
+** a read-lock on the same table, then SQLite arbitrarily selects one of
+** the other connections to use as the blocking connection.
+**
+** ^(There may be at most one unlock-notify callback registered by a
+** blocked connection. If sqlite3_unlock_notify() is called when the
+** blocked connection already has a registered unlock-notify callback,
+** then the new callback replaces the old.)^ ^If sqlite3_unlock_notify() is
+** called with a NULL pointer as its second argument, then any existing
+** unlock-notify callback is canceled. ^The blocked connections
+** unlock-notify callback may also be canceled by closing the blocked
+** connection using [sqlite3_close()].
+**
+** The unlock-notify callback is not reentrant. If an application invokes
+** any sqlite3_xxx API functions from within an unlock-notify callback, a
+** crash or deadlock may be the result.
+**
+** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always
+** returns SQLITE_OK.
+**
+** <b>Callback Invocation Details</b>
+**
+** When an unlock-notify callback is registered, the application provides a
+** single void* pointer that is passed to the callback when it is invoked.
+** However, the signature of the callback function allows SQLite to pass
+** it an array of void* context pointers. The first argument passed to
+** an unlock-notify callback is a pointer to an array of void* pointers,
+** and the second is the number of entries in the array.
+**
+** When a blocking connections transaction is concluded, there may be
+** more than one blocked connection that has registered for an unlock-notify
+** callback. ^If two or more such blocked connections have specified the
+** same callback function, then instead of invoking the callback function
+** multiple times, it is invoked once with the set of void* context pointers
+** specified by the blocked connections bundled together into an array.
+** This gives the application an opportunity to prioritize any actions
+** related to the set of unblocked database connections.
+**
+** <b>Deadlock Detection</b>
+**
+** Assuming that after registering for an unlock-notify callback a
+** database waits for the callback to be issued before taking any further
+** action (a reasonable assumption), then using this API may cause the
+** application to deadlock. For example, if connection X is waiting for
+** connection Y's transaction to be concluded, and similarly connection
+** Y is waiting on connection X's transaction, then neither connection
+** will proceed and the system may remain deadlocked indefinitely.
+**
+** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
+** detection. ^If a given call to sqlite3_unlock_notify() would put the
+** system in a deadlocked state, then SQLITE_LOCKED is returned and no
+** unlock-notify callback is registered. The system is said to be in
+** a deadlocked state if connection A has registered for an unlock-notify
+** callback on the conclusion of connection B's transaction, and connection
+** B has itself registered for an unlock-notify callback when connection
+** A's transaction is concluded. ^Indirect deadlock is also detected, so
+** the system is also considered to be deadlocked if connection B has
+** registered for an unlock-notify callback on the conclusion of connection
+** C's transaction, where connection C is waiting on connection A. ^Any
+** number of levels of indirection are allowed.
+**
+** <b>The "DROP TABLE" Exception</b>
+**
+** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost
+** always appropriate to call sqlite3_unlock_notify(). There is however,
+** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
+** SQLite checks if there are any currently executing SELECT statements
+** that belong to the same connection. If there are, SQLITE_LOCKED is
+** returned. In this case there is no "blocking connection", so invoking
+** sqlite3_unlock_notify() results in the unlock-notify callback being
+** invoked immediately. If the application then re-attempts the "DROP TABLE"
+** or "DROP INDEX" query, an infinite loop might be the result.
+**
+** One way around this problem is to check the extended error code returned
+** by an sqlite3_step() call. ^(If there is a blocking connection, then the
+** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
+** the special "DROP TABLE/INDEX" case, the extended error code is just
+** SQLITE_LOCKED.)^

+
+ For successful execution, you have to copy the file, local.properties, into the following pathes:
+ - oic-resource/csdk/
+ - oic-resource/csdk/libcoap-4.1.1
+
+
+2. Time.c, Time.h should be copied in your machine and they should be refered in the Makefile as followings
+
+ Makefile path: / oic-resource / csdk / libcoap-4.1.1 / makefile
+
+ path to be modified:
+
+ - INCD_ARD_TIME = -I$(ARDUINO_DIR)/libraries/Time ---> for Time.h
+ - SDIR_ARD_TIME = $(ARDUINO_DIR)/libraries/Time ---> for Time.c

+Release notes
+Release date: Aug 5th, 2014.
+OS: Ubuntu 12.0.4 and above
+Requires boost version 1.55 to build.
+NOTE: Boost is not distributed but should be installed in the Ubuntu machine.
+
+What\92s new?
+Class OCPlatform (Header file: OCPlatform.h)
+registerResource API (signature update)
+\95This API provides the ability to register the resource with its name, type and list of properties
+\95Signature of this API has changed. The API takes reference to resource handle which will be filled upon successful registration. Other parameters include resource URI, resource Type, resource interface, entity handler address and resource property (whether discoverable, observable etc.).
+\95NOTE: This applies to server side functionality.
+\95NOTE: This API might get modified to accommodate for resource collection in future.
+
+notifyObservers API
+\95This new API provides the ability to notify core that resource\92s attributes have changed. When entity handler is ready to indicate core that a resource has changed, notifyObservers API needs to be invoked.
+\95This API takes resource handle as the only parameter.
+\95NOTE: This applies to server side functionality.
+\95NOTE: This API might get modified to accommodate for resource collection in future.
+
+Class OCResource (Header file: OCResource.h)
+
+get API
+\95This new API provides the ability to get the attributes of a resource. This API takes a callback as parameter. Callback will be invoked with Attribute map which will provide representation of the resource. Callback will also include error code for GET operation.
+\95NOTE: This applies to client side functionality.
+\95NOTE: This API might get modified to accommodate for resource collection in future.
+
+put API
+\95This new API provides the ability to set the attributes of a resource via PUT.
+\95This API takes Attribute map, query parameter map and a callback as parameters. Callback will be invoked with Attribute map which will provide current representation of the resource. Callback will also include error code for PUT operation.
+\95NOTE: This applies to client side functionality.
+\95NOTE: This API might get modified to accommodate for resource collection in future.
+
+Observe API
+\95This new API provides the ability for the client to set observation on a resource
+\95This API provides callback as a parameter. Callback will be invoked with attribute map and with an error code for this operation.
+\95NOTE: This applies to client side functionality.
+
+cancelObserve API
+\95This new API provides the ability for the client to cancel observation on a resource
+\95This API provides callback as a parameter. Callback will be invoked with error code for this operation.
+\95NOTE: This applies to client side functionality.
+Class OCResourceRequest (Header file: OCResourceRequest.h)
+NOTE: This applies to server side functionality.
+
+getRequestType API
+\95This new API provides the ability to retrieve the type of request. This could be GET, PUT (and in future POST and DELETE).
+
+getQueryParams API
+\95This new API provides the ability to retrieve the query parameters from the URL request.
+
+getRequestHandlerFlag API
+\95This new API provides the ability to retrieve the request handler flag on the URL request. This could be either INIT, REQUEST or OBSERVE flag.
+
+getResourceRepresentation API
+\95This new API provides the ability to retrieve attribute representation of the resource.
+
+Class OCResourceResponse (Header file: OCResourceResponse.h)
+NOTE: This applies to server side functionality.
+
+setErrorCode API
+\95This new API provides the ability to set the error code
+
+setResourceRepresentation API
+\95This new API provides the ability to set the attribute representation of a resource.
+
+Other Notes:
+1. Security model is still open.
+2. APIs have OCStackResult as return type. This is will indicate success or failure for the API operation.
+3. Resource collection/hierarchy APIs are not checked into the code base. They will be given as separate header files.
+4. Query parameters are not used in this deliverable.
+5. Only single client observer has been tested.
+6. Maximum length of URI supported is 64 bytes
+7. Maximum length of response (for GET, PUT) from server is 128 bytes.
+
+
+How to build:
+1. Root folder oic-resource consists of \91OIC\92 folder. Inside OIC folder there is a Makefile.
+2. Before building, make sure to have contents from oic-utilities repo at the folder level where oic-resource is.
+3. Use \91make\92 to build the entire OIC code. This would build the C++ SDK, stack and samples.
+
+Samples:
+1. We have a sample for hosting a resource on a server and a sample for client which will be able to discover resources.
+2. Server sample location: OIC/examples/simpleserver.cpp
+3. Client sample location: OIC/examples/simpleclient.cpp
+4. In simpleserver.cpp, inside main,
+
+PlatformConfig cfg;
+cfg.ipAddress = "134.134.161.33";
+
+Modify the above IP address to the IP address of the machine where this server is running.
+
+Similarly, in simpleclient.cpp, inside main, modify the IP address to the IP address of the machine where the client is running.
+
+The server and client can run in same machine or in different machines.
+
+5. To run simpleServer do \91./simpleServer\92 and to run simpleClient do \91./simpleClient\92.

+===============================================================================
+== How to Build Things Manager ==
+===============================================================================
+
+Once the source code is downloaded in your local specific folder, you may follow
+the steps to build and execute Things Manager and its applications.
+In this context, we assume that the code was downloaded into 'oic' folder.
+
+=======================================
+1. Download source code
+=======================================
+
+From the url, you can download Things Manager source code;
+https://www.iotivity.org/downloads
+
+Once you download the codes, and Make sure that the downloaded code structure is as follows;
+Four directories for oic; extlib, resource, service, and tools.
+
+oic/extlib
+oic/resource
+oic/service
+oic/tools
+
+The path for Things Manager is as following;
+
+oic/service/things-manager
+
+The things-manager directory includes following sub directories;
+
+Directories Description
+oic/service/things-manager/sdk : The SDK APIs for applications is located.
+ The main functionality of this SDK is to provide
+ developer-friendly APIs of Things manager component
+ to application developers.
+oic/service/things-manager/sampleapp : It is the sample application on Ubuntu.
+ Basically, the input and output of application
+ on Ubuntu are displayed in the console.
+oic/service/things-manager/build : Whole library files and binary files would be made
+ in this folder
+
+
+
+=======================================
+2. Build
+=======================================
+Simply, type "make" to build things manager as follows;
+
+/oic/service/things-manager/build/linux$ make
+
+=======================================
+3. Build the API reference documentation
+=======================================
+To build the API reference documentation:
+a. Navigate to oic-resource/docs folder using the terminal window.
+b. Run the following command:
+
+ $ doxygen
+
+This command builds the API reference documentation in the output directory.
+
+The output directory for this command is oic-resource/docs/html/index.html.

+== How to build IoTivity projects ==
+
+IoTivity includes a series of projects. You can find all these projects here:
+ https://gerrit.iotivity.org/gerrit/#/admin/projects/
+
+You can build IoTivity project on Linux / Windows / MAC OSX for various OS(
+Linux, Tizen, Android, Arduino, Windows, MAC OSX, IOS ...).
+The output of the build is in:
+ <top directory of the project>/out/<target_os>/<target_arch>/<build_type>/
+e.g.
+ oic-resource/out/android/armeabi-v7a/release/.
+
+This document takes 'iotivity' project as example, the way to build other
+projects is almost the same.
+
+=== IoTivity project build tool scons ===
+
+Scons is a cross-platform build tool, its usage is quite similar to GNU make.
+To build a project, you just require to run following command at the directory
+where a SConstruct file exists(SConstruct is the entrance of scons build, it's
+equivalent to Makefile of 'make') :
+ $ scons [options] [target]
+
+In additional, usually the scons build script of a project provides useful help
+information(include build options). To see the help information:
+ $ scons [options] -h
+
+Note: If no value is specified for an option, the default value will be used.
+The change of options value may impact the output.
+
+
+=== Prerequites ===
+
+* 1. Scons
+
+Please refer to the following page to install scons:
+ http://www.scons.org/doc/production/HTML/scons-user.html#chap-build-install
+(Note: on Windows, install Python 2.x before installing scons)
+
+* 2. IDE/SDK Prerequites
+To build for some OS (Android / Arduino / IOS ...), an IDE/SDK may be required,
+please go to the relative page to download and install the required IDE/SDK.
+
+Android:
+To build for Android, Andorid NDK and SDK are required.
+ Android NDK: http://developer.android.com/tools/sdk/ndk/index.html
+ Android SDK: http://developer.android.com/sdk/index.html
+(Note: as in some IoTivity projects, C++11 features are used, recommend Android
+ NDK >= r10, according to our test result r10c is the best one currently)
+
+Arduino:
+To build for Arduino, Arduino IDE is required.
+ Arduino IDE: http://arduino.cc/en/Main/Software
+ (Note: recommend install Arduino IDE >=1.5.7)
+
+Arduino builds are dependent on latest Time library. Download it from here:
+ http://www.pjrc.com/teensy/td_libs_Time.html
+and extract to <arduino_ide_root>/libraries/
+
+(Note: If you are using Arduino IDE 1.5.8 BETA on Windows, it may pop up some
+dll isn't found. please copy relative dll from the IDE directory to
+C:\Windows\SysWOW64. IDE 1.5.7 doesn't have this issue. Other version IDE isn't
+tested.)
+
+Apple:
+To build for Mac OSX or IOS, Xcode is required.
+ Xcode: https://developer.apple.com/xcode/downloads/
+
+Java:
+To build the Java code, JDK is required.
+ JDK: http://www.oracle.com/technetwork/java/javase/downloads/index.html
+(If the project doesn't include Java code or you wouldn't like build the
+Java codes, this isn't required)
+
+(Note: for convenience, suggest add the IDE/SDK path in environment variable,
+so you don't need to add it in command line each time. The build script will
+guide you to do that.)
+
+* 3. External libraries
+For Android and IOS build, most of the external libraries are provided as
+binary in oic-utilities project (https://oic-review.01.org/gerrit/oic-utilities).
+Please download it in the same directory as other IoTivity projects. If it's
+in different directory, an additional option (OIC_UITLS) will be required. The
+build command should be:
+ $ scons OIC_UITLS=<path to oic-utilities> [other options] [target]
+
+(Note: for convenience, you can also add it in environment variable. So you
+don't need to add this option in command line each time.)
+ e.g.:
+ $ export OIC_UITLS=<path to oic-utilities project>
+
+
+=== Build IoTivity project on Linux(Ubuntu) ===
+
+Generally, it's required to specify the target OS and target ARCH, that's to say
+tell Scons which OS and which ARCH you'd like build this project for. By default,
+the target OS and ARCH is the same as the host.
+
+Some more options may be required, please care the 'error' notification when build.
+For help about how to set an option, please run:
+ $ scons TARGET_OS=xxx TARGET_ARCH=yyy [XXX=zzz ...] -h
+
+1. Build IoTivity project for Linux
+ $ cd <top directory of the project>
+ $ sudo apt-get install libboost-dev libboost-program-options-dev libexpat1-dev
+ $ scons
+
+2. Build IoTivity project for Android
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=android TARGET_ARCH=xxx
+(xxx can be x86, armeabi, armeabi-v7a, armeabi-v7a-hard. To see all of its
+allowed value, please execute command 'scons TARGET_OS=android -Q -h')
+
+Note: Currently as x86_64/arm64_v8a external library binaries aren't provided,
+you may meet link problem if build executable binary which depends on external
+library for x86_64/arm64_v8a.
+
+3. Build IoTivity project for Arduino
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=arduino TARGET_ARCH=xxx BOARD=yyy
+(xxx can be avr, arm; yyy is the name of the board, to get its allowed value
+run: scons TARGET_OS=arduino TARGET_ARCH=xxx -h. You may see a option 'CPU' in
+the output of above command line, that's due to some boards have different
+processors, to specify the processor, add 'CPU=zzz' in the command line. If no
+'CPU' option exists, that means the board only support one kind of processor,
+it's unnecessary to specify it)
+
+4. Build Iotivity project for Tizen
+ $ cd <top directory of the project>
+ $ gbs build -A xxx --packaging-dir tools/tizen/
+(xxx can be i586 or armv7l, we provide the spec file required by gbs tool at
+toools/tizen directory. gbs is default build tool for Tizen platfrom, we can
+refer the following wiki to setup Tizen development environment:
+https://source.tizen.org/documentation/developer-guide/getting-started-guide)
+
+=== Build IoTivity project on Windows ===
+
+1. Build IoTivity project for Android(It's the same as on Ubuntu)
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=android TARGET_ARCH=xxx
+(xxx can be x86, armeabi, armeabi-v7a, armeabi-v7a-hard ...)
+
+2. Build IoTivity project for Arduino(It's the same as on Ubuntu)
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=arduino TARGET_ARCH=xxx BOARD=yyy
+(xxx can be avr, arm; yyy is the name of the board, to get its allowed value
+run: scons TARGET_OS=arduino TARGET_ARCH=xxx -h. You may see a option 'CPU' in
+the output of above command line, that's due to some boards have different
+processor, to specify the processor, add 'CPU=zzz' in the command line. If no
+'CPU' option exists, that means the board only support one kind of processor,
+it's unnecessary to specify it)
+
+
+Note: Currently most IoTivity project doesn't support Windows, so you can't set
+TARGET_OS to 'windows' except the project support Windows.
+
+That's to say if the project doesn't support Windows, run:
+ $ scons TARGET_OS=windows ....
+or run on Windows
+ $ scons
+may always fail.
+
+
+=== Build IoTivity project on Mac OSX ===
+
+1. Build IoTivity project for Mac OSX
+ $ cd <top directory of the project>
+ $ scons SYS_VERSION=yyy
+(yyy is the OSX version, e.g. 10.9)
+
+2. Build IoTivity project for Android(It's the same as on Ubuntu)
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=android TARGET_ARCH=xxx
+(xxx can be x86, armeabi, armeabi-v7a, armeabi-v7a-hard)
+
+3. Build IoTivity project for IOS
+ $ cd <top directory of the project>
+ $ scons TARGET_OS=ios TARGET_ARCH=xxx SYS_VERSION=yyy
+(xxx can be i386, x86_64, armv7, armv7s, arm64, yyy is IOS version, e.g. 7.0)
+
+Note:
+1) for convenience, a script (auto_build.sh) is provided to run possible build
+at once. Following is the usage:
+
+To build:
+ $ auto_build.sh <path-to-android-ndk> <path-to-arduino-home>
+To clean:
+ $ auto_build.sh -c
+
+2) For Arduino build, the Time library should >=1.3. The old can only be built
+with Arduino IDE 1.0.x

+== How to write IoTivity build script ==
+
+IoTivity projects are built with Scons. Scons is a cross-platform build tool,
+it's quite similar to 'make'. 'SConstruct' is the entrance of scons build, it's
+equivalent to 'Makefile' to 'make'.
+
+This document only a brief reference. Detail about how to write scons script,
+please refer to:
+ http://www.scons.org/doc/production/HTML/scons-user.html#
+
+== Background: How to control source code compiling ==
+
+Environment is a base conception of Scons. An environment is a collection of
+values that can affect how a program is built.
+
+e.g. There is a C file named hello.c, enter the following into a file named
+SConstruct:
+ env = Environment()
+ env.Program('H', 'hello.c')
+
+When run Scons in console, following will be executed:
+cc -o hello.o -c hello.c
+cc -o H hello.o
+
+If you would like keep debug information in the binary, '-g' flag should be added
+when build the source code. To do this, append a C compiler flags as following:
+ env = Environment()
+ env.AppendUnique(CFLAGS = ['-g'])
+ env.Program('H', 'hello.c')
+
+When run Scons, following will be executed:
+cc -o hello.o -c -g hello.c
+cc -o H hello.o
+
+In above example, 'CFLAGS' is changed. Following list the frequently used keys:
+
+CFLAGS: General options that are passed to the C compiler
+CCFLAGS: General options that are passed to the C & C++ compiler
+CXXFLAGS: General options that are passed to the C++ compiler
+CPPPATH: The directories that the preprocessor will search for include headers.
+CPPDEFINES: Platform independent specification of C preprocessor definitions.
+
+Note: CPPPATH and CPPDEFINES is common for all compiler. But others are
+compiler specific, when change the key value, it may requried to specify the
+target platform(actually the compiler).
+
+e.g.
+ env.AppendUnique(CPPPATH = ['.', 'include'])
+ env.AppendUnique(CPPDEFINES = ['NDEBUG', 'VER_TEST'])
+Above two lines are fine for all target platform. but below line:
+ env.AppenUnique(CXXFLAGS = ['-g'])
+is only fine for gcc compiler, as '-g' is a gcc flag, other compiler may don't
+understand it. so it may should be:
+ if target_os not in ['windows', 'winrt']:
+ env.AppenUnique(CXXFLAGS = ['-g'])
+
+Still take the hello.c as example. Assume hello.h is in ./include/ directory,
+#include "hello.h"
+int main(int argc, char** argv)
+{
+#ifdef LANG_FR
+ printf("Bonjour\n");
+#else
+ printf("Hello\n");
+#endif
+}
+
+The Scons configure file should as following:
+ env = Environment()
+ env.AppendUnique(CFLAGS = ['-g'])
+ env.AppendUnique(CPPPATH = ['include'])
+ env.AppendUnique(CPPDEFINES = ['LANG_FR'])
+ env.Program('H', 'hello.c')
+
+When run Scons, following will be executed:
+cc -o hello.o -c -g -Iinclude -DLANG_FR hello.c
+cc -o H hello.o
+
+=== Get extra information ===
+
+In above example, 'target_os' is used. How to get it?
+
+User can build IoTivity project on Linux / Windows / MAC OSX for various
+targets(Linux, Tizen, Android, Arduino, Windows, MAC OSX, IOS ...). Most
+platform specific configures have been done in the common scripts which are in
+build_common. The common scripts prepare an environment named 'env' with
+target platform specific configuration.
+
+When write IoTivity project build script, you can get this environment as
+following:
+ Import('env')
+
+You can use 'env' directly after import it. You can also clone a new environment
+and update its keys.
+
+ new_env1 = Clone('env')
+ new_env2 = Clone('env')
+ new_env1.AppendUnqiue(xxx = [...])
+ new_env2.AppendUnqiue(xxx = [...])
+
+The 'env' environment contains platform specific configuration, besides, there is
+some common information. You can get the information with following line:
+ env.get('XXX')
+or
+ env['XXX']
+
+XXX is the information name, below are the extra information added by IoTivity
+common scrirpts:
+BUILD_DIR: the path of the build directory, all output are in this directory
+SRC_DIR: the path of the top directory of the source code
+OIC_UTILS: the path of oic-utilities project
+RELEASE: build type, boolean. True - release build, False - debug build
+TARGET_OS: the name of the target OS. The possible value depends on the host
+ platform. Bellow is the list of host and possible target OS. (darwin means
+ MAC OSX)
+ linux: linux / android / arduino / tizen
+(the line means on Linux, you can build the project for Linux/Android/Arduino/Tizen)
+ windows: windows / winrt / android / arduino
+ darwin: darwin / ios / android / arduino
+
+TARGET_ARCH: the target CPU arch. Its possible value depend on the target OS.
+ Bellow list the target OS and allowed CPU architecture.
+ linux: x86 / x86_64 / arm / arm64
+(above line means if the target OS is Linux, the CPU arch can be x86/x86_64/arm/arm64)
+ android: x86 / x86_64 / armeabi / armeabi-v7a / armeabi-v7a-hard / arm64-v8a
+ windows: x86 / amd64 / arm
+ winrt: arm
+ darwin: i386 / x86_64
+ ios: i386 / x86_64 / armv7 / armv7s / arm64,
+ arduino: avr / arm
+
+=== Extra functions ===
+
+For convenience, in the common scripts, some extra functions are added.
+
+PrintTargets(): print all targets in the help information.
+AppendTarget(target): add 'target' into targets list, when use PrintTargets,
+ the 'target' will be print.
+InstallTarget(files, name): it takes the same action as AppendTarget, besides,
+ it installs the 'files' to BUILD_DIR.
+
+Following functions are only for Arduino:
+ImportLib(lib): Arduino IDE includes many libraries. By default, no library is
+compiled. If your project use some libraries, you can import the library by
+this function. 'lib' is the name of the library to import. The 'include' path
+will be auto added to the environment and the library will be built and linked
+into the final binary.
+
+CreateBin('bin', src): For Arduino, after build the program, it's required to
+be converted into specific format (e.g .hex). This function will genearate the
+required .hex (and .eep if target arch is avr) file.
+
+UploadHelp(): For different board, the upload command line is different, this
+function print the recommended upload command line. You can see the recommended
+upload command line in the help information(the output of command "scons
+[options] -h")
+
+==== Scripts Hierarchy ====
+
+Scons provides a function 'SConscript(scripts, [exports, variant_dir, duplicate])'
+It tells scons to execute one or more subsidiary configuration files(A script,
+usually named SConscript). Take below project hierarchy as example to show how
+to organize the scripts.
+
+ prj
+ |-------prj_1
+ | |--------sub_prj_11
+ | |--------sub_prj_..
+ | |--------sub_prj_1n
+ |-------prj_2
+ |
+ | ... ...
+ |
+ |-------prj_n
+
+As above project hierarchy, in 'SConstruct' file in the 'prj' directory, there
+should include some lines like these:
+
+#Please change this part according to the organization of your projects.
+#Note: To make the output is in build_dir, the path of the scripts should
+#be relevant to build_dir
+SConscript(build_dir + 'prj_1/SConscript')
+SConscript(build_dir + 'prj_2/SConscript')
+... ...
+SConscript(build_dir + 'prj_n/SConscript')
+
+
+It's the same, in the 'prj_1/SConscript', there should include lines like
+these:
+SConscript('sub_prj_11/SConscript')
+... ...
+SConscript('sub_prj_1n/SConscript')
+
+The path is relevant to 'prj_1/SConscript'. You can also use the full path
+build_dir + 'prj_1/sub_prj_1x/SConscript', but it's not recommended.
+
+Above just to show a recommended way to manage subsidiary scripts. You don't
+need restrictly follow it.
+
+==== The content of a typical script ====
+
+After run the scripts in build_common (usally it's done at the beginning of
+SConstruct), an global environment 'env' is exported, 'env' has include the
+default configuration of the target OS and arch. 'env' is used in all projects,
+should avoid to change its keys. To avoid change 'env', usually clone 'env' and
+update it accroding to the requirement of cuurent sub project. Then specify the
+target(usually binary) to build.
+
+Below is an example:
+ # import the global enviroment 'env'
+ Import('env')
+
+ # Clone a new enviroment from 'env'
+ new_env = env.Clone()
+
+ # Update the new enviroment, usally include add header file paths,
+ # library path, libs to link and other compiler flags. This part is
+ # optional. If not present, the default configuration will be used
+ new_env.AppeneUnique(xxx = [ .... ])
+
+ # Specify the target(application, library, object or others) to build
+ ts = new_env.Program('progam_name', [source_list])
+
+ # Install the target (optional)
+ # If it's an important library or daemon to be published
+ new_env.InstallTarget(ts, 'target_name')
+or
+ # If is't examples or test program or others will not be published
+ new_env.Alias('target_name', ts)
+ new_env.AppendTarget('target_name')
+
+==== Tips ====
+1. library order: if A lib use B lib, both A and B are linked to target T, the
+ when specify libraries, A should in front of B, otherwise there may be link
+ error.
+2. On android:
+ (1)'pthread' is in libc. So don't use '-lpthread' for android
+ (2)By default 'rtti' and 'exception' is disabled, to enable it, you need
+ add flags '-frtti' and '-fexceptions'
+ (3)If STL is used, need link 'gnustl_static' library
