The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `<wchar.h>' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *Note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options.

A session is a group of clients, +each of which has a particular state. The session is controlled by a +network service called the session manager. +The session manager issues commands to its clients on behalf of the +user. These commands may cause clients to save their state or to +terminate. It is expected that the client will save its state in such +a way that the client can be restarted at a later time and resume its +operation as if it had never been terminated. A client's state might +include information about the file currently being edited, the current +position of the insertion point within the file, or the start of an +uncommitted transaction. The means by which clients are restarted is +unspecified by this protocol. + + + +For purposes of this protocol, a client of the +session manager is defined as a connection to the session manager. A +client is typically, though not necessarily, a process running an +application program connected to an X display. However, a client may +be connected to more than one X display or not be connected to any X +displays at all. + + + + + + The Session Management Library + + +The Session Management Library (SMlib) is a low-level +"C" language interface to XSMP. It is expected that higher level +toolkits, such as Xt, will hide many of the details of session +management from clients. Higher level toolkits might also be developed +for session managers to use, but no such effort is currently under way. + + + + + SMlib has two parts to it: + + One set of functions for clients that want to be part of a session + One set of functions for session managers to call + + + + +Some applications will use both sets of functions and act as +nested session managers. That is, they will be +both a session manager and a client of another session. An example is +a mail program that could start a text editor for editing the text of +a mail message. The mail program is part of a regular session and, at +the same time, is also acting as a session manager to the editor. + + + +Clients initialize by connecting to the session manager and obtaining +a client-ID that uniquely identifies them in +the session. The session manager maintains a list of properties for +each client in the session. These properties describe the client's +environment and, most importantly, describe how the client can be +restarted (via an SmRestartCommand). Clients are +expected to save their state in such a way as to allow multiple +instantiations of themselves to be managed independently. For +example, clients may use their client-ID as part of a filename in +which to store the state for a particular instantiation. The +client-ID should be saved as part of the SmRestartCommand +so that the client will retain the same ID after it is restarted. + + + +Once the client initializes itself with the session manager, it must +be ready to respond to messages from the session manager. For +example, it might be asked to save its state or to terminate. In the +case of a shutdown, the session manager might give each client a +chance to interact with the user and cancel the shutdown. + + + + + Understanding SMlib's Dependence on ICE + + +The X Session Management Protocol is layered on top of the +Inter-Client Exchange (ICE) Protocol. The ICE +protocol is designed to multiplex several protocols over a single +connection. As a result, working with SMlib requires a little +knowledge of how the ICE library works. + + + +The ICE library utilizes callbacks to process messages. When a client +detects that there is data to read on an ICE connection, it should +call the IceProcessMessages function. +IceProcessMessages will read the message header +and look at the major opcode in order to determine which protocol the +message was intended for. The appropriate protocol library will then +be triggered to unpack the message and hand it off to the client via a +callback. + + + +The main point to be aware of is that an application using SMlib must +have some code that detects when there is data to read on an ICE +connection. This can be done via a select call +on the file descriptor for the ICE connection, but more +typically, XtAppAddInput will be used to register +a callback that will invoke IceProcessMessages +each time there is data to read on the ICE connection. + + + +To further complicate things, knowing which file descriptors to +call select on requires an understanding of how +ICE connections are created. On the client side, a call must be made +to in order to open a connection +with a session manager. will +internally makea call into IceOpenConnection +which will, in turn, determine if an ICE connection already exists +between the client and session manager. Most likely, a connection +will not already exist and a new ICE connection will be created. The +main point to be aware of is that, on the client side, it is not +obvious when ICE connections get created or destroyed, because +connections are shared when possible. To deal with this, the ICE +library lets the application register watch procedures that will be +invoked each time an ICE connection is opened or closed. These watch +procedures could be used to add or remove ICE file descriptors from +the list of descriptors to call select on. + + + +On the session manager side, things work a bit differently. The +session manager has complete control over the creation of ICE +connections. The session manager has to first +call IceListenForConnections in order to start +listening for connections from clients. Once a connection attempt is +detected, IceAcceptConnection must be called, and +the session manager can simply add the new ICE file descriptor to the +list of descriptors to call select on. + + + + +For further information on the library functions related to ICE connections, +see the Inter-Client Exchange Library +standard. + + + + +Header Files and Library Name + + +Applications (both session managers and clients) should include the +header file <X11/SM/SMlib.h>. +This header file defines all of the SMlib data structures and function +prototypes. SMlib.h includes the +header file <X11/SM/SM.h>, +which defines all of the SMlib constants. + + + +Because SMlib is dependent on ICE, applications should link against +SMlib and ICElib by using + . + + + + + Session Management Client (<acronym>Smc</acronym>) Functions + + + This section discusses how Session Management clients: + + Connect to the Session Manager + Close the connection + Modify callbacks + Set, delete, and retrieve Session Manager properties + Interact with the user + Request a “Save Yourself” + Request a “Save Yourself Phase 2” + Complete a “Save Yourself” + Use Smc informational functions + Handle Errors + + + + +Connecting to the Session Manager + + +To open a connection with a session manager, +use + + + + + SmcConn SmcOpenConnection + char *network_ids_list + SmPointer context + int xsmp_major_rev + int xsmp_minor_rev + unsigned long mask + SmcCallbacks *callbacks + char *previous_id + char **client_id_ret + int error_length + char *error_string_ret + + + + + + network_ids_list + Specifies the network ID(s) of the session manager. + + + context + +A pointer to an opaque object or NULL.

No more than error_length bytes are used. + + + + + +The network_ids_list argument is a +null-terminated string containing a list of network IDs for the session +manager, separated by commas. If network_ids_list +is NULL, the value of +the SESSION_MANAGER environment variable will be used. +Each network ID has the following format: + + + + + + + + + tcp/<hostname>:<portnumber> + or + + + decnet/<hostname>::<objname> + or + + + local/<hostname>:<path> + + + + + + + + +An attempt will be made to use the first network ID. If that fails, +an attempt will be made using the second network ID, and so on. + + + +After the connection is established, +registers the client with the session manager. If the client is being +restarted from a previous session, previous_id +should contain a null terminated string representing the client ID from the +previous session. If the client is first joining the session, +previous_id should be set to NULL. +If previous_id is specified but is determined +to be invalid by the session manager, SMlib will re-register the +client with previous_id set to NULL. + + + +If succeeds, it returns an +opaque connection pointer of type SmcConn and the +client_id_ret argument contains the client ID to be +used for this session. The client_id_ret should be +freed with a call to free when no longer needed. On +failure, returns +NULL, and the reason for failure is returned in +error_string_ret. + + + +Note that SMlib uses the ICE protocol to establish a connection with +the session manager. If an ICE connection already exists between the +client and session manager, it might be possible for the same ICE +connection to be used for session management. + + + +The context argument indicates how willing the client is to share the +ICE connection with other protocols. If context is NULL, +then the caller is always willing to share the connection. If context is not +NULL, then the caller is not willing to use a previously +opened ICE connection that has a different non-NULL +context associated with it. + + + +As previously discussed +(section 3, +“Understanding SMlib's Dependence on ICE”), the +client will have to keep track of when ICE connections are created or +destroyed (using IceAddConnectionWatch +and IceRemoveConnectionWatch and will have to +call IceProcessMessages each time +a select shows that there is data to read on an +ICE connection. For further information, see the +Inter-Client Exchange Library +standard. + + + +The callbacks argument contains a set of callbacks used to respond to +session manager events. The mask argument specifies which callbacks +are set. All of the callbacks specified in this version of SMlib are +mandatory.

When all the properties have +been set, the client calls + + + +If interact_style is +SmInteractStyleNone the +client must not interact with the user while saving state. +If interact_style is +SmInteractStyleErrors the +client may interact with the user only if an error condition arises. +If interact_style is +SmInteractStyleAny then the +client may interact with the user for any purpose. Because only one +client can interact with the user at a time, the client must +call and wait for an +“Interact” message from the session manager. When the +client is done interacting with the user, it +calls The client may only +call after it receives a +“Save Yourself” message and before it +calls + + + +If save_type is SmSaveLocal the +client must update the properties to reflect its current state. Specifically, +it should save enough information to restore the state as seen by the +user of this client. It should not affect the state as seen by other users. +If save_type is SmSaveGlobal +the user wants the client to commit all of its data to permanent, globally +accessible storage. +If save_type is SmSaveBoth +the client should do both of these (it should first commit the data to +permanent storage before updating its properties). + + + +Some examples are as follows: + + + +If a word processor were sent a “Save Yourself” with a +type of SmSaveLocal it could create a temporary +file that included the current contents of the file, the location of +the cursor, and other aspects of the current editing session. It +would then update its SmRestartCommand property with +enough information to find this temporary file. + + +If a word processor were sent a “Save Yourself” with a +type of SmSaveGlobal it would simply save the +currently edited file. + + +If a word processor were sent a “Save Yourself” with a +type of SmSaveBoth it would first save the +currently edited file. It would then create a temporary file with +information such as the current position of the cursor and what file +is being edited. Finally, it would update its +SmRestartCommand property with enough information +to find the temporary file. + + + + + +The shutdown argument specifies whether the +system is being shut down. +The interaction is different depending on whether or not shutdown is +set. If not shutting down, the client should save its state and wait +for a “Save Complete” message. If shutting down, the +client must save state and then prevent interaction until it receives +either a “Die” or a “Shutdown Cancelled.” + + + +The fast argument specifies that the client +should save its state as quickly as possible.

The only difference is that the application does not +supply its client ID at register time. On POSIX systems, +this should be of type SmLISTofARRAY8. + + SmCurrentDirectory + +On POSIX-based systems, this specifies the value of the +current directory that needs to be set up prior to starting the +SmProgram and should of type SmARRAY8. + + SmDiscardCommand + +The discard command contains a command that when delivered to the host +that the client is running on (determined from the connection), will +cause it to discard any information about the current state.

This restart command should ensure that the client restarts +with the specified client-ID. + + SmResignCommand + +A client that sets the SmRestartStyleHint +to SmRestartAnyway uses this property to specify a +command that undoes the effect of the client and removes any saved state. +As an example, consider a user that runs xmodmap which +registers with the Session Manager, +sets SmRestartStyleHint +to SmRestartAnyway, and then +terminates. To allow the Session Manager (at the user's request) to +undo this, xmodmap would register a +SmResignCommand that undoes the effects of +the xmodmap. + + SmRestartStyleHint + +If the SmRestartStyleHint is present, it will contain the +style of restarting the client prefers. If this style is not specified, +SmRestartIfRunning is assumed. +The possible values are as follows: + + + + + + + + + Name + Value + + + + + SmRestartIfRunning + 0 + + + SmRestartAnyway + 1 + + + SmRestartImmediately + 2 + + + SmRestartNever + 3 + + + + + + + +The SmRestartIfRunning style is used in the usual case. +The client should be restarted in the next session if it was running at +the end of the current session. + + + +The SmRestartAnyway style is used to tell the Session +Manager that the application should be restarted in the next session even if +it exits before the current session is terminated. It should be noted that +this is only a hint and the Session Manager will follow the policies +specified by its users in determining what applications to restart. + + + +A client that uses SmRestartAnyway should also set the +SmResignCommand and SmShutdownCommand +properties to commands that undo the state of the client after it exits. + + + +The SmRestartImmediately style is like SmRestartAnyway, but, in addition, the client is meant to run continuously. If the client exits, the Session Manager should try to restart it in the current session. + + + +SmRestartNever style specifies that the client does not +wish to be restarted in the next session. + + + SmShutdownCommand + +This command is executed at shutdown time to clean up after a client +that is no longer running but retained its state by setting +SmRestartStyleHint to +SmRestartAnyway. The client must not remove any saved +state as the client is still part of the session. As an +example, consider a client that turns on a camera at start up time. +This client then exits. At session shutdown, the user wants the +camera turned off. This client would set the +SmRestartStyleHint to +SmRestartAnyway and would register +a SmShutdownCommand that would turn off the camera. + + SmUserID + +Specifies the user ID.

The session +manager can cause clients to save their state, to shut down, and to be +restarted into a previously saved state. This protocol is layered on +top of the X.Org ICE protocol. + + + + + + + Acknowledgments + + +First I would like to thank the entire ICCCM and Intrinsics +working groups for the comments and suggestions. I would like to make special +thanks to the following people (in alphabetical order), Jordan Brown, +Ellis Cohen, Donna Converse, Vania Joloboff, Stuart Marks, Ralph Mor +and Bob Scheifler. + + + + + Definitions and Goals + + +The purpose of the X Session Management Protocol (XSMP) is +to provide a uniform mechanism for users to save and restore their sessions. +A session is a group of clients, each +of which has a particular state. The session is controlled by a +network service called the session manager. +The session manager issues commands to its +clients on behalf of the user. These commands may cause clients to +save their state or to terminate. It is expected that the client will +save its state in such a way that the client can be restarted at a +later time and resume its operation as if it had never been +terminated. A client's state might include information about the file +currently being edited, the current position of the insertion point +within the file, or the start of an uncommitted transaction. The +means by which clients are restarted is unspecified by this +protocol. + + + +For purposes of this protocol, a client +of the session manager is defined as a connection to the session +manager. A client is typically, though not necessarily, a process +running an application program connected to an X Window System +display. However, a client may be connected to more than one X +display or not be connected to any X displays at all. + + + +This protocol is layered on top of the X Consortium's ICE protocol and +relies on the ICE protocol to handle connection management and authentication. + + + + + + Overview of the Protocol + + +Clients use XSMP to register themselves with the session manager (SM). +When a client starts up, it should connect to the SM. The client +should remain connected for as long as it runs. A client may resign +from the session by issuing the proper protocol messages before +disconnecting. Termination of the connection without notice will be +taken as an indication that the client died unexpectedly. + + + +Clients are expected to save their state in such a way as to allow +multiple instantiations of themselves to be managed independently. A +unique value called a client-ID is +provided by the protocol for the purpose of disambiguating multiple +instantiations of clients. Clients may use this ID, for example, as +part of a filename in which to store the state for a particular +instantiation. The client-ID should be saved as part of the command +used to restart this client +(the RestartCommand) so that the client +will retain the same ID after it is restarted. Certain small pieces +of state might also be stored in the RestartCommand. For example, an +X11 client might place a '-twoWindow' option in its RestartCommand to +indicate that it should start up in two window mode when it is +restarted. + + + +The client finds the network address of the SM in a system-dependent +way. On POSIX systems an environment +variable called SESSION_MANAGER +will contain a list of network IDs. Each id will contain the +transport name followed by a slash and the (transport-specific) +address. A TCP/IP address would look like this: + + tcp/hostname:portnumber + +where the hostname is a fully qualified domain name. +A Unix Domain address looks like this: + + local/hostname:path + +A DECnet address would look like this: + + decnet/nodename::objname + + + + +If multiple network IDs are specified, they should be separated by commas. + + + Rationale + +There was much discussion over whether the XSMP protocol should use X +as the transport protocol or whether it should use its own independent +transport. It was decided that it would use an independent protocol +for several reasons. First, the Session Manager should be able to +manage programs that do not maintain an X connection. Second, the X +protocol is not appropriate to use as a general-purpose transport +protocol. Third, a session might span multiple displays. + + + +The protocol is connection based, because there is no other way for +the SM to determine reliably when clients terminate. + + + +It should be noted that this protocol introduces another single point +of failure into the system. Although it is possible for clients to +continue running after the SM has exited, this will probably not be +the case in normal practice. Normally the program that starts the SM +will consider the session to be terminated when the SM exits (either +normally or abnormally). + + + +To get around this would require some sort of rendezvous server that +would also introduce a single point of failure. In the absence of a +generally available rendezvous server, XSMP is kept simple in the +hopes of making simple reliable SMs. + + + + +Some clients may wish to manage the programs they start. For example, +a mail program could start a text editor for editing the text of a +mail message. A client that does this is a session manager itself; it +should supply the clients it starts with the appropriate connection +information (i.e., the SESSION_MANAGER environment variable) +that specifies a connection to itself instead of to the top level session +manager. + + + +Each client has associated with it a list of properties. A property +set by one client is not visible to any other client. These +properties are used for the client to inform the SM of the client's +current state. When a client initially connects to the SM, there are +no properties set. + + + + + Data Types + + +XSMP messages contain several types of data. Both the SM and the +client always send messages in their native byte order. Thus, both +sides may need to byte-swap the messages received. The need to do +byte-swapping is determined at run-time by the ICE protocol. + + + +If an invalid value is specified for a field of any of the enumerated +types, a BadValue error message must be sent by +the receiver of the message to the sender of the message. + + + + + + + + + Type Name + Description + + + + + BOOL + False or True + + + INTERACT_STYLE + None Errors or Any + + + DIALOG_TYPE + Error or Normal + + + SAVE_TYPE + Global Local or Both + + + CARD8 + a one-byte unsigned integer + + + CARD16 + a two-byte unsigned integer + + + CARD32 + a four-byte unsigned integer + + + ARRAY8 + a sequence of CARD8s + + + LISTofARRAY8 + a sequence of ARRAY8s + + + PROPERTY + a property name (an ARRAY8), a type name, and a value of that type + + + LISTofPROPERTY + a counted collection of ­PROPERTYs. + + + + + + + + + Protocol Setup and Message Format + + +To start the XSMP protocol, the client sends the server an +ICE ProtocolSetup message. All XSMP messages are +in the standard ICE message format. The message's major opcode is +assigned to XSMP by ICE at run-time. The different parties (client +and SM) may be assigned different major opcodes for XSMP. Once +assigned, all XSMP messages issued by this party will use the same +major opcode. The message's minor opcode specifies which protocol +message this message contains. + + + + + Client Identification String + +A client ID is a string of XPCS characters encoded in ISO Latin 1 (ISO +8859-1). No null characters are allowed in this string. The client +ID string is used in the Register­Client +and Register­ClientReply messages. + + + +Client IDs consist of the pieces described below. The ID is formed by +concatenating the pieces in sequence, without separator characters. +All pieces are padded on the left with '0' +characters so as to fill the specified length. Decimal numbers are +encoded using the characters '0' through +'9', and hexadecimal numbers using the characters +'0' through '9' and +'A' through 'F'. + + + + +Version. This is currently the character '1'. + + + Address type and address. The address type will be one of + + '1' a 4-byte IPv4 address encoded as 8 hexadecimal digits + '2' a 6-byte DECNET address encoded as 12 hexadecimal digits + '6' a 16-byte IPv6 address encoded as 32 hexadecimal digits + + + + +The address is the one of the network addresses of the machine where +the session manager (not the client) is running. For example, the IP +address 198.112.45.11 would be encoded as the string +"QC6702D0B". + + + + Time stamp. A 13-digit decimal number specifying + the number of milliseconds since 00:00:00 UTC, January 1, 1970. + + + + Process-ID type and process-ID. The process-ID type will be one of + + '1' a POSIX process-ID encoded as a 10-digit decimal number. + + + +The process-ID is the process-ID of the session manager, not of a client. + + + + +Sequence number. This is a four-digit decimal number. It is +incremented every time the session manager creates an ID. After +reaching "Q9999" it wraps to "Q0000". + + Rationale + +Once a client ID has been assigned to the client, the client keeps +this ID indefinitely. If the client is terminated and restarted, it +will be reassigned the same ID. It is desirable to be able to pass +client IDs around from machine to machine, from user to user, and from +session manager to session manager, while retaining the identity of +the client. This, combined with the indefinite persistence of client +IDs, means that client IDs need to be globally unique. The +construction specified above will ensure that any client ID created by +any user, session manager, and machine will be different from any other. + + + + + + + + Protocol + +The protocol consists of a sequence of messages as described below. +Each message type is specified by an ICE minor opcode. A given +message type is sent either from a client to the session manager or +from the session manager to a client; the appropriate direction is +listed with each message's description. For each message type, the +set of valid responses and possible error messages are listed. The +ICE severity is given in parentheses following each error class. + + + +RegisterClient [Client → SM] + + previous-ID: ARRAY8 + + Valid Responses: RegisterClientReply + + Possible Errors: BadValue (CanContinue) + + + +The client must send this message to the SM to register the client's +existence. If a client is being restarted from a previous session, +the previous-ID field must contain the client +ID from the previous session. For new clients, +previous-ID should be of zero length. + + + +If previous-ID is not valid, +the SM will send a BadValue +error message to the client. At this point the SM reverts to the +register state and waits for another RegisterClient +The client should then send a RegisterClient with a +null previous-ID field. + + + +RegisterClientReply [Client ← SM] + + client-ID: ARRAY8 + + + +The client-ID specifies a unique identification +for this client. If the client had specified an ID in the +previous-ID field of the +RegisterClient message, +client-ID will be identical to the previously +specified ID. If previous-ID was null, +client-ID will be a unique ID freshly generated +by the SM. The client-ID format is specified in +section 6. + + + +If the client didn't supply a previous-ID field to +the Register­Client message, the SM must send +a SaveYourself message with type = Local, +shutdown = False, interact-style = None, and fast = False immediately +after the RegisterClientReply The client should +respond to this like any other Save­Yourself +message. + + + +SaveYourself [Client ← SM] + + type: SAVE_TYPE + shutdown: BOOL + interact-style: INTERACT_STYLE + fast: BOOL + + Valid Responses: + SetProperties + DeleteProperties + GetProperties + SaveYourselfDone + SaveYourselfPhase2Request + InteractRequest + + + +The SM sends this message to a client to ask it to save its state. +The client writes a state file, if necessary, and, if necessary, +uses SetProperties to inform the SM of how to +restart it and how to discard the saved state. During this process it +can, if allowed by interact-style, request permission +to interact with +the user by sending an InteractRequest message. +After the state has been saved, or if it cannot be successfully saved, +and the properties are appropriately set, the client sends +a SaveYourselfDone message. If the client wants +to save additional information after all the other clients have +finished changing their own state, the client should +send SaveYourselfPhase2Request instead +of SaveYourselfDone The client must then freeze +interaction with the user and wait until it receives +a SaveComplete Die or +a ShutdownCancelled message. + + + +If interact-style is None the +client must not interact with the user while saving state. If the +interact-style +is Errors the client may interact with the user +only if an error condition arises. If interact-style +is Any then the client may interact with the user +for any purpose. This is done by sending +an Interact­Request message. The SM will +send an Interact message to each client that sent +an Interact­Request The client must postpone +all interaction until it gets the Interact +message. When the client is done interacting it should send the SM +an Interact­Done message. +The Interact­Request message can be sent any +time after a Save­Yourself and before +a Save­Yourself­Done + + + +Unusual circumstances may dictate multiple interactions. The client +may initiate as many Interact­Request +- Interact - InteractDone +sequences as it needs before it sends SaveYourselfDone + + + +When a client receives Save­Yourself and has +not yet responded Save­Yourself­Done to a +previous Save­Yourself it must send +a Save­Yourself­Done and may then begin +responding as appropriate to the newly received +Save­Yourself + + + +The type field specifies the type of information that +should be saved: Global Local +or Both The Local type +indicates that the application must update the properties to reflect +its current state, send +a Save­Yourself­Done and continue. +Specifically it should save enough information to restore the state as +seen by the user of this client. It should not affect the state as +seen by other users. The Global type indicates +that the user wants the client to commit all of its data to permanent, +globally-accessible storage. Both indicates that +the client should do both of these. If Both is +specified, the client should first commit the data to permanent +storage before updating its SM properties. + + + Examples + +If a word processor was sent a SaveYourself with +a type of Local it could create a temporary file +that included the current contents of the file, the location of the +cursor, and other aspects of the current editing session. It would +then update its Restart­Command property with +enough information to find the temporary file, and +its Discard­Command with enough information +to remove it. + + + +If a word processor was sent a SaveYourself with +a type of Global it would simply save the +currently edited file. + + + +If a word processor was sent a SaveYourself with +a type of Both it would first save the currently +edited file. It would then create a temporary file with information +such as the current position of the cursor and what file is being +edited. It would then update +its Restart­Command property with enough +information to find the temporary file, and +its Discard­Command with enough information +to remove it. + + + +Once the SM has send SaveYourself to a client, it +can't send another SaveYourself to that client until +the client either responds with a SaveYourselfDone or +the SM sends a ShutdownCancelled + + + + Advice to Implementors + +If the client stores local any state in a file or similar "external" +storage, it must create a distinct copy in response to +each SaveYourself message. +It must not simply refer to a previous +copy, because the SM may discard that previous saved state using +a DiscardCommand without knowing that it is +needed for the new checkpoint. + + + + +The shutdown field specifies whether the system is +being shut down. + + + Rationale + +The interaction may be different depending on whether or not shutdown is set. + + + + +The client must save and then must prevent interaction until it +receives a SaveComplete Die +or a Shutdown­Cancelled because anything the +user does after the save will be lost. + + + +The fast field specifies whether or not the client +should save its state as quickly as possible. For example, if the SM knows +that power is about to fail, it should set the fast +field to True. + + + +SaveYourselfPhase2 [Client → SM] + + Valid Responses: + SetProperties + DeleteProperties + GetProperties + SaveYourselfDone + InteractRequest + + + +The SM sends this message to a client that has previously sent +a SaveYourselfPhase2Request message. This +message informs the client that all other clients are in a fixed state +and this client can save state that is associated with other clients. + + + Rationale + +Clients that manager other clients (window managers, workspace +managers, etc) need to know when all clients they are managing are +idle, so that the manager can save state related to each of the +clients without being concerned with that state changing. + + + +The client writes a state file, if necessary, and, if necessary, +uses SetProperties to inform the SM of how to +restart it and how to discard the saved state. During this process it +can request permission to interact with the user by sending +an InteractRequest message.

Some properties have predefined semantics. +See section 11, +“Predefined Properties.” + + + +The protocol specification recommends that property names used for +properties not defined by the standard should begin with an +underscore.

The only difference is that the +application doesn't supply its client id at register time. On POSIX +systems the type should be a LISTofARRAY8. + + + + CurrentDirectory + +On POSIX-based systems specifies the value of the current directory that +needs to be set up prior to starting the program and should be of type ARRAY8. + + + + DiscardCommand + +The discard command contains a command that when delivered to the host +that the client is running on (determined from the connection), will +cause it to discard any information about the current state. If this +command is not specified, the SM will assume that all of the client's +state is encoded in the Restart­Command On +POSIX systems the type should be LISTofARRAY8. + + + + Environment + +On POSIX based systems, this will be of type LISTofARRAY8 where the +ARRAY8s alternate between environment variable name and environment +variable value. + + + + ProcessID + +This specifies an OS-specific identifier for the process. On POSIX +systems this should of type ARRAY8 and contain the return value of +getpid() turned into a Latin-1 (decimal) string. + + + + Program + +The name of the program that is running. On POSIX systems this should +be the first parameter passed to execve and should be of type ARRAY8. + + + + RestartCommand + +The restart command contains a command that when delivered to the host +that the client is running on (determined from the connection), will +cause the client to restart in its current state. On POSIX-based +systems this is of type LISTofARRAY8 and each of the elements in the +array represents an element in the argv array. This restart command +should ensure that the client restarts with the specified +client-ID. + + + + ResignCommand + + +A client that sets the RestartStyleHint +to RestartAnyway uses this property to specify a +command that undoes the effect of the client and removes any saved +state. + + Example +A user runs xmodmap. xmodmap registers with the SM, +sets Restart­Style­Hint +to Restart­Anyway and then terminates. In +order to allow the SM (at the user's request) to undo this, xmodmap +would register a Resign­Command that undoes +the effects of the xmodmap. + + + + + RestartStyleHint + + +If the RestartStyleHint property is present, it will contain the style +of restarting the client prefers. If this flag isn't +specified, RestartIfRunning is assumed. The +possible values are as follows: + + + + + + + + + + Name + Value + + + + + RestartIfRunning + 0 + + + RestartAnyway + 1 + + + RestartImmediately + 2 + + + RestartNever + 3 + + + + + + +The RestartIfRunning style is used in the usual +case. The client should be restarted in the next session if it is +connected to the session manager at the end of the current session. + + + +The RestartAnyway style is used to tell the SM +that the application should be restarted in the next session even if +it exits before the current session is terminated. It should be noted +that this is only a hint and the SM will follow the policies specified +by its users in determining what applications to restart. + + + Rationale +This can be specified by a client which supports (as MS-Windows +clients do) a means for the user to indicate while exiting that +restarting is desired. It can also be used for clients that spawn +other clients and then go away, but which want to be restarted. + + + +A client that uses RestartAnyway should also set +the ResignCommand and ShutdownCommand +properties to commands that undo the state of the client after it exits. + + + +The RestartImmediately style is +like RestartAnyway but in addition, the client is +meant to run continuously. If the client exits, the SM should try to +restart it in the current session. + + + Advice to Implementors +It would be wise to sanity-check the frequency which +which RestartImmediately clients are restarted, +to avoid a sick client being restarted continuously. + + + +The RestartNever style specifies that the client +does not wish to be restarted in the next session. + + + Advice to Implementors +This should be used rarely, if at all. It will cause the client to be +silently left out of sessions when they are restarted and will +probably be confusing to users. + + + + + + ShutdownCommand + + +This command is executed at shutdown time to clean up after a client +that is no longer running but retained its state by +setting RestartStyleHint +to RestartAnyway The command must not remove any +saved state as the client is still part of the session. + + Example +A client is run at start up time that turns on a camera. This client +then exits. At session shutdown, the user wants the camera turned +off. This client would set the Restart­Style­Hint +to Restart­Anyway and would register a +Shutdown­Command that would turn off the camera. + + + + + UserID + +Specifies the user's ID.
