+ External projects were using non-public header ares_dns.h, make public again (#376)
+
+ It appears some outside projects were relying on macros in ares_dns.h, even though it doesn't appear that header was ever meant to be public. That said, we don't want to break external integrators so we should distribute this header again.

+- ares_getaddrinfo(): duplicate hints ai_socktype and ai_protocol into output
+
+ ai_socktype and ai_protocol were ignored from the hints input. They are now
+ duplicated into the output as expected. Currently no sanity checks on
+ proper values are taking place.

+- ares_parse_{a,aaaa}_reply could return larger *naddrttls than passed in
+
+ If there are more ttls returned than the maximum provided by the requestor, then

+ Reorganize source tree (#349)
+
+ Originally started by Daniel Stenberg (@bagder) with #123, this patch reorganizes the c-ares source tree to have a more modern layout. It also fixes out of tree builds for autotools, and automatically builds the tests if tests are enabled. All tests are passing which tests each of the supported build systems (autotools, cmake, nmake, mingw gmake). There may be some edge cases that will have to be caught later on for things I'm not aware of.

+- [apenn-msft brought this change]
+
+ Tests should use dynamic system-assigned ports rather than static port (#346)
+
+ The c-ares test suite was hardcoded to use port 5300 (and possibly 5301, 5302) for the test suite. Especially in containers, there may be no guarantee these ports are available and cause tests to fail when they could otherwise succeed. Instead, request the system to assign a port to use dynamically. This is now the default. To override, the test suite still takes the "-p <port>" option as it always has and will honor that.

+- Unset members of the addr struct contain garbage values (#343)
+
+ When generating the ares_sockaddr data by getaddrinfo() it was only filling
+ in certain members while leaving others uninitialized. This left garbage
+ data if a user tried to use the unset values. memset() the ares_sockaddr
+ to 0 prior to filling in the values to prevent this.

+ Avoid buffer overflow in RC4 loop comparison (#336)
+
+ The rc4 function iterates over a buffer of size buffer_len who's maximum
+ value is INT_MAX with a counter of type short that is not guaranteed to
+ have maximum size INT_MAX.
+
+ In circumstances where short is narrower than int and where buffer_len
+ is larger than the maximum value of a short, it may be possible to loop
+ infinitely as counter will overflow and never be greater than or equal
+ to buffer_len.
+
+ The solution is to make the comparison be between types of equal width.
+ This commit defines counter as an int.

+ Parse SOA records from ns_t_any response (#103)
+
+ Added the capability of parsing SOA record from a response buffer of ns_t_any type query, this implementation doesn't interfere with existing T_SOA query's response as that too is treated as a list of records. The function returns ARES_EBADRESP if no SOA record is found(as per RFC).
+
+ The basic idea of sticking to RFC that a ns_t_any too should return an SOA record is something open for discussion but I have kept the functionality intact as it was previously i.e the function returns ARES_EBADRESP if it doesn't find a SOA record regardless of which response it is parsing i.e. T_SOA or T_ANY.
+
+ Note that asking for T_ANY is generally a bad idea:

+
+ This moves the blacklist check from being Windows-specific to being a general feature of config_nameservers(), no matter the nameserver source. It also simplifies the ares_ipv6_server_blacklisted() implementation to not parse and re-parse the blacklisted IPv6 addresses from strings on every check. I think they're almost as easy to read as a sequence of hex bytes in an array initializer, and it's definitely less work on each trip through the code.

+
+ Harden and rationalize c-ares timeout computation (#187)
+
+ * Harden and rationalize c-ares timeout computation
+ * Remove the rand() part of the timeout calculation completely.
+
+ When c-ares sends a DNS query, it computes the timeout for that request as follows:
+
+ timeplus = channel->timeout << (query->try_count / channel->nservers);
+ timeplus = (timeplus * (9 + (rand () & 7))) / 16;
+ I see two issues with this code. Firstly, when either try_count or channel->timeout are large enough, this can end up as an illegal shift.
+
+ Secondly, the algorithm for adding the random timeout (added in 2009) is surprising. The original commit that introduced this algorithm says it was done to avoid a "packet storm". But, the algorithm appears to only reduce the timeout by an amount proportional to the scaled timeout's magnitude. It isn't clear to me that, for example, cutting a 30 second timeout almost in half to roughly 17 seconds is appropriate. Even with the default timeout of 5000 ms, this algorithm computes values between 2812 ms and 5000 ms, which is enough to cause a slightly latent DNS response to get spuriously dropped.
+
+ If preventing the timers from all expiring at the same time really is desirable, then it seems better to extend the timeout by a small factor so that the application gets at least the timeout it asked for, and maybe a little more. In my experience, this is common practice for timeouts: applications expect that a timeout will happen at or after the designated time (but not before), allowing for delay in detecting and reporting the timeout. Furthermore, it seems like the timeout shouldn't be extended by very much (we don't want a 30 second timeout changing into a 45 second timeout, either).
+
+ Consider also the documentation of channel->timeout in ares_init_options():
+
+ The number of milliseconds each name server is given to respond to a query on the first try. (After the first try, the timeout algorithm becomes more complicated, but scales linearly with the value of timeout.) The default is five seconds.
+
+ In the current implementation, even the first try does not use the value that the user supplies; it will use anywhere between 56% and 100% of that value.
+
+ The attached patch attempts to address all of these concerns without trying to make the algorithm much more sophisticated. After performing a safe shift, this patch simply adds a small random timeout to the computed value of between 0 ms and 511 ms. I could see limiting the random amount to be no greater than a proportion of the configured magnitude, but I can't see scaling the random with the overall computed timeout. As far as I understand, the goal is just to schedule retries "not at the same exact time", so a small difference seems sufficient.
+
+ UPDATE: randomization removed.

-- Improvement by Brad House:
-
- This patch addresses an issue in which a response could be sent back to the
- source port of a client from a different address than the request was made to.
- This is one form of a DNS cache poisoning attack.
-
- The patch simply uses recvfrom() rather than recv() and validates that the
- address returned from recvfrom() matches the address of the server we have
- connected to. Only necessary on UDP sockets as they are connection-less, TCP
- is unaffected.

-- Fix by George Neill:

-
-* Aug 4 2008 (Daniel Stenberg)
-- Fix by Tofu Linden:
-
- The symptom:
- * Users (usually, but not always) on 2-Wire routers and the Comcast service
- and a wired connection to their router would find that the second and
- subsequent DNS lookups from fresh processes using c-ares to resolve the same
- address would cause the process to never see a reply (it keeps polling for
- around 1m15s before giving up).
-
- The repro:
- * On such a machine (and yeah, it took us a lot of QA to find the systems
- that reproduce such a specific problem!), do 'ahost www.secondlife.com',
- then do it again. The first process's lookup will work, subsequent lookups
- will time-out and fail.
+Version 1.14.0 (16 Feb 2018)
- The cause:
- * init_id_key() was calling randomize_key() *before* it initialized
- key->state, meaning that the randomness generated by randomize_key() is
- immediately overwritten with deterministic values. (/dev/urandom was also
- being read incorrectly in the c-ares version we were using, but this was
- fixed in a later version.)
- * This makes the stream of generated query-IDs from any new c-ares process
- be an identical and predictable sequence of IDs.
- * This makes the 2-Wire's default built-in DNS server detect these queries
- as probable-duplicates and (erroneously) not respond at all.

-- Vlad Dinulescu fixed two outstanding valgrind reports:
+ Fix DNS server lookup breaking with Android O due to Android removing access to net.dns# system properties. (#148)
+
+ As of Android 8 (Oreo) access to net.dns# has been removed (https://developer.android.com/about/versions/oreo/android-8.0-changes.html). The reasoning given is that it, "improves privacy on the platform". Currently c-ares uses this to get the list of DNS servers.
+
+ Now the only way to access the DNS server list is by using the Connectivity Manager though Java. This adds the necessary JNI code to use the Connectivity Manager and pull the DNS server list. The old way using __system_property_get with net.dns# remains for compatibilty.
+
+ Using the Connectivity Manager requires the ACCESS_NETWORK_STATE permission to be set on the app. Existing applications most likely are not setting this and keeping the previous method as a fallback will at the very least ensure those apps don't break on older versions of Android. They will need to add this permission for Android 8 compatibility.
+
+ Included in the patch are two initalization functions which are required. The JVM must be registered as well as the Connectivity Manager itself. There is no way to get the Connectivity Manager except though Java. Either being passed down to C directly or by passing in an Android Context which can be used to get the Connectivity Manager. Examples are provided in the documentation.
- 1. In ares_query.c , in find_query_by_id we compare q->qid (which is a short
- int variable) with qid, which is declared as an int variable. Moreover,

- sets only the first two bytes of qid. I think that qid should be declared as
- "unsigned short" in this function.

+- [Gergely Nagy brought this change]
- 3. The third problem is that Valgrind assumes that query->qid is not
- initialised correctly. And it does that because query->qid is set from
- DNS_HEADER_QID(qbuf); Valgrind says that qbuf has unitialised bytes. And
- qbuf has uninitialised bytes because of channel->next_id . And next_id is
- set by ares_init.c:ares__generate_new_id() . I found that putting short r=0
- in this function (instead of short r) makes all Valgrind warnings go away.

+- ares_version.h: bump version
- The c-ares library implementation uses a DNS "Transaction ID" field that is

- incremented (++) between consecutive calls and is therefore rather
- predictable. In general, predictability of DNS Transaction ID is a well
- known security problem (e.g.
- http://bak.spc.org/dms/archive/dns_id_attack.txt) and makes a c-ares based
- implementation vulnerable to DNS poisoning. Credit goes to Amit Klein
- (Trusteer) for identifying this problem.
+Version 1.13.0 (20 Jun 2017)

- generating unique IDs. It starts by obtaining a key with reasonable entropy
- which is used with an RC4 stream to generate the cryptographically secure
- transaction IDs.
+Daniel Stenberg (20 Jun 2017)

+- test: Feed in short NAPTR
- Problem: Calling ares_init() for each lookup can be unnecessarily resource
- intensive. On windows, it must LoadLibrary() or search the registry
- on each call to ares_init(). On unix, it must read and parse
- multiple files to obtain the necessary configuration information. In
- a single-threaded environment, it would make sense to only
- ares_init() once, but in a heavily multi-threaded environment, it is
- undesirable to ares_init() and ares_destroy() for each thread created
- and track that.
+- test: Add fuzz input with short NAPTR
- Solution: Create ares_save_options() and ares_destroy_options() functions to
- retrieve and free options obtained from an initialized channel. The
- options populated can be used to pass back into ares_init_options(),
- it should populate all needed fields and not retrieve any information
- from the system. Probably wise to destroy the cache every minute or
- so to prevent the data from becoming stale.
+- test: add ares_parse_naptr_reply to fuzzer
-- Daniel S added ares_process_fd() to allow applications to ask for processing

+ Windows DNS server sorting (#81)
+
+ Original Patch From Brad Spencer:
+ https://c-ares.haxx.se/mail/c-ares-archive-2016-04/0000.shtml
+
+ My modifications include:
+ * Dynamically find GetBestRoute2 since it is a Windows Vista+ symbol, and will fall back to prior behavior when not available.
+ * Prefer get_DNS_AdaptersAddresses as the modifications should alleviate the concerns which caused us to prefer get_DNS_NetworkParams
+ * Update AppVeyor to use MinGW-w64 instead of the legacy MinGW
+ * Fix compile error in test suite for Windows.
+
+ Original message from patch below:
+
+ From: Brad Spencer <bspencer@blackberry.com>
+ Date: Fri, 29 Apr 2016 14:26:23 -0300
+
+ On Windows, the c-ares DNS resolver tries first to get a full list of
+ DNS server addresses by enumerating the system's IPv4/v6 interfaces and
+ then getting the per-interface DNS server lists from those interfaces
+ and joining them together. The OS, at least in the way the c-ares
+ prefers to query them (which also may be the only or best way in some
+ environments), does not provide a unified list of DNS servers ordered
+ according to "current network conditions". Currently, c-ares will then
+ try to use them in whatever order the nested enumeration produces, which
+ may result in DNS requests being sent to servers on one interface
+ (hosting the current default route, for example) that are only intended
+ to be used via another interface (intended to be used when the first
+ interface is not available, for example). This, in turn, can lead to
+ spurious failures and timeouts simply because of the server address
+ order that resulted because of the enumeration process.
+
+ This patch makes the (safe?) assumption that there is no other better
+ rule to chose which interface's DNS server list should be prioritized.
+ After all, a DNS lookup isn't something "per network"; applications
+ don't look up "these DNS names on this interface and those DNS names on
+ that interface". There is a single resource pool of DNS servers and the
+ application should presume that any server will give it the "right"
+ answer. However, even if all DNS servers are assumed to give equally
+ useful responses, it is reasonable to expect that some DNS servers will
+ not accept requests on all interfaces. This patch avoids the problem by
+ sorting the DNS server addresses using the Windows IPv4/v6 routing tables.
+
+ For example, a request to DNS server C on interface 2 that is actually
+ sent over interface 1 (which may happen to have the default route) may
+ be rejected by or not delivered to DNS server C. So, better to use DNS
+ servers A and B associated with interface 1, at least as a first try.
+
+ By using the metric of the route to the DNS server itself as a proxy for
+ priority of the DNS server in the list, this patch is able to adapt
+ dynamically to changes in the interface list, the DNS server lists per
+ interface, which interfaces are active, the routing table, and so on,
+ while always picking a good "best" DNS server first.
+
+ In cases where any DNS server on any interface will do, this patch still
+ seems useful because it will prioritize a lower-metric route's (and thus
+ interface's) servers.

+- api: add ARES_OPT_NOROTATE optmask value
+
+ Fix up a couple of problems with configuring whether c-ares rotates
+ between different name servers between requests.
+
+ Firstly, ares_save_options() returns (in *optmask) the value of
+ (channel->optmask & ARES_OPT_ROTATE), which doesn't necessarily
+ indicate whether the channel is or is not actually doing rotation.
+ This can be confusing/incorrect if:
+ - the channel was originally configured without ARES_OPT_ROTATE
+ (so it appears that the channel is not rotating)
+ - the /etc/resolv.conf file includes the 'rotate' option
+ (so the channel is actually performing rotation).
+
+ Secondly, it is not possible to reliably configure a channel
+ to not-rotate; leaving off ARES_OPT_ROTATE is not enough, since
+ a 'rotate' option in /etc/resolv.conf will turn it on again.
+
+ Therefore:
+ - add an ARES_OPT_NOROTATE optmask value to allow explicit
+ configuration of no-rotate behaviour
+ - in ares_save_options(), report the value of channel->rotate
+ as exactly one of (optmask & ARES_OPT_ROTATE) or
+ (optmask & ARES_OPT_NOROTATE).
+
+ In terms of back-compatibility:
+ - existing apps that set ARES_OPT_ROTATE will continue to rotate,
+ and to have ARES_OPT_ROTATE reported back from ares_save_options()
+ - existing apps that don't set ARES_OPT_ROTATE will continue to
+ use local config/defaults to decide whether to rotate, and will
+ now get ARES_OPT_ROTATE or ARES_OPT_NOROTATE reported back from
+ ares_save_options() rather than 0.
+
+- ares_init_options: only propagate init failures from options
+
+ Commit 46bb820be3a8 ("ares_init_options: don't lose init failure")
+ changed init behaviour so that earlier errors in initialization
+ weren't lost. In particular, if the user passes in specific
+ options but they are not applied (e.g. because of an allocation
+ failure), that failure needs to be reported back to the user; this
+ also applies when duplicating a channel with ares_dup().
+
+ However, other initialization failures can be ignored and
+ overridden -- in particular, if init_by_resolv_conf() or
+ init_by_environment() fail, then falling back to default values
+ is OK.
+
+ So only preserve failures from the init_by_options() stage, not
+ from all initialization stages.
+
+ Fixes issue 60.

+
+ When fuzzing with AFL, if the LLVM-based instrumentation is

+ times over the fuzzing entrypoint (similar to libFuzzer's normal
+ mode of execution) with different data. This is much (e.g. 10x)
+ faster.
+
+ Add code to support this, by checking whether __AFL_LOOP is
+ defined at compile-time.
+
+ Also, shift the code to effectively be C rather than C++.
+
+- test: simplify deps for fuzzer entrypoint
+
+ No need to depend on the rest of the test code (ares-test.h) for
+ the fuzzer entrypoint; this makes the entrypoint slightly simpler
+ to build with LLVM's libFuzzer.
+
+ Also shift the code to effectively be C rather than C++

-- configure fix for detecting a member in the sockaddr_in6 struct which failed
- on ipv6-enabled HP-UX 11.00
+Daniel Stenberg (9 Mar 2016)
+- [Brad House brought this change]
+
+ configure: check if tests can get built before enabled
+
+ The current approach for disabling tests is not a good solution because
+ it forces you to pass --disable-tests, rather than auto-detect if your
+ system can support the tests in the first place. Many (most?) systems
+ do not have C++11. This also causes issues when chain-building c-ares,
+ the hosting system needs to be updated to support passing this
+ additional flag if necessary, it doesn't seem reasonable to add this
+ requirement which breaks compatibility.
+
+ This change auto-detects if the system can build the tests and
+ automatically disable them if it cannot. If you pass --enable-tests to
+ configure and the system cannot build them either due to lack of system
+ support, or because cross-compilation is being used, it will throw an
+ appropriate error since the user indicated they really did want the
+ tests.

+ errors are no longer swallowed in `ares_init_options`. This has exposed
+ a previously unknown bug in `lookups` initialization code.
+
+ If there is no lookup configuration in `resolv.conf`,
+ `init_by_resolv_conf` will attempt to read it from other files available
+ on the system. However, some of these files may have restricted
+ permissions (like `600`), which will lead to `EACCESS` errno, which in
+ turn is handled like a fatal error by `init_by_resolv_conf`.
+
+ However, it sounds illogical that this error should be handled as a
+ fatal. There is a `init_by_defaults` call that overrides `lookups` with
+ default value, and certainly possible absence of lookup information is
+ the reason why this function exists in a first place!
+
+ I suggest handling any `fopen` errors as non-fatal ones, allowing to
+ pick up the `lookups` value from different config files, or to pick up

+- test: Ignore SIGPIPE in tests
+
+- test: More initialization tests
+
+- test: Improve containerized test mechanism
+
+ Aim is to ensure that code coverage information can escape the
+ container. To do this:
+ - Enter a new mount namespace too, so that we can...
+ - Bind mount the expected source directory into the container
+ - Share memory with the sub-process so coverage information is
+ shared too.
+
+- test: Make contained tests easier to write
+
+- test: Add framework for containerized testing
+
+ On Linux we can potentially use user and UTS namespaces to run a test
+ in a pseudo-container with:
+ - arbitrary filesystem (e.g. /etc/resolv.conf, /etc/nsswitch.conf, /etc/hosts)
+ - arbitrary hostname/domainname.
+
+ Include a first pass at the framework code to allow this, along with a
+ first test case that uses the container.
+
+- test: Use a longer timeout for less flakiness
+
+ Having occasional test failures from timeout before multiple
+ queries can complete, so up the default timeout for the test
+ from 100ms to 1500ms.
+
+- test: Make failure tests more robust
+
+ Different platforms will do different numbers of allocations
+ in the processing of a given API call; just check that the
+ return code is either success or ENOMEM, and free off any
+ returned state in the former case.
+
+ Also cope with ECONNREFUSED as well as ENOTFOUND.
+
+- test: Get test code building under Windows
+
+ - Initial nmake file based off library nmake file
+ - Cast socket call arguments to (char *)
+ - Use wrapper sclose() that maps to closesocket() or close()
+ - Build a config.h indicating presence of headers
+ - Conditionally include netdb.h
+ - Remove unnecessary include of sys/socket.h
+ - Force longer bitmask for allocation failure tracking
+ - Call WSAStartup() / WSACleanup() in main()

+- test: Add a simple multi-server test
+
+ Check rotate option does something
-- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
- does not work with IPv6. Also provided an implementation of bitncmp from
- BIND for systems that do not supply this function. This will be used to add
- IPv6 support to sortlist.
+- test: Allow for multiple mock servers
+
+ - Update the MockServer to allow separate specification of
+ UDP and TCP ports
+ - Have an array of mock servers listening on consecutive
+ sets of ports.
+ - Rename Process(fd) to ProcessFD(fd) to avoid confusion.
+ - Initialize channel by using the new ares_set_servers_ports()
+ entrypoint, so multiple ports on the same loopback address
+ can be used.
+
+- test: Update test for set/get_servers variants

+- test: Add AppVeyor config file for Windows build
+
+- test: Add configuration for a Travis build
+
+ Cover Linux & OSX on the container infrastructure, but install
+ a later G++ to satisfy the tests' need for C++11.
+
+ Use a build matrix to include a variety of build variants:
+ - ASAN
+ - UBSAN
+ - LSAN
+ - Coverage via coveralls.io
+
+ test: invoke ASAN and coverage in Travis build
+
+ Also shift to use explicit build matrix
+
+ test: Use coveralls.io for coverage tracking
+
+ test: Add a build with UBSAN
+
+ Also expand and re-order the setting of environment variables
+ for easier modification.
+
+ test: Add LSAN build to Travis config
+
+- test: Add initial unit tests for c-ares library
+
+ The tests are written in C++11, using the GoogleTest and GoogleMock
+ frameworks. They have their own independent autoconf setup, so that
+ users of the library need not have a C++ compiler just to get c-ares
+ working (however, the test/configure.ac file does assume the use of
+ a shared top-level m4/ directory). However, this autoconf setup has
+ only been tested on Linux and OSX so far.
+
+ Run with "./arestest", or "./arestest -v" to see extra debug info.
+ The GoogleTest options for running specific tests are also
+ available (e.g. "./arestest --gtest_filter=*Live*").
+
+ The tests are nowhere near complete yet (currently hitting around
+ 60% coverage as reported by gcov), but they do include examples
+ of a few different styles of testing:
+
+ - There are live tests (ares-test-live.cc), which assume that the
+ current machine has a valid DNS setup and connection to the
+ internet; these tests issue queries for real domains but don't
+ particularly check what gets returned. The tests will fail on
+ an offline machine.
+
+ - There a few mock tests (ares-test-mock.cc) that set up a fake DNS
+ server and inject its port into the c-ares library configuration.
+ These tests allow specific response messages to be crafted and
+ injected, and so are likely to be used for many more tests in
+ future.
+
+ - To make this generation/injection easier, the dns-proto.h file
+ includes C++ helper classes for building DNS packets.
+
+ - Other library entrypoints that don't require network activity
+ (e.g. ares_parse_*_reply) are tested directly.
+
+ - There are few tests of library-internal functions that are not
+ normally visible to API users (in ares-test-internal.cc).
+
+ - A couple of the tests use a helper method of the test fixture to
+ inject memory allocation failures, using the earlier change to the
+ library to allow override of malloc/realloc/free.
+
+ - There is also an entrypoint to allow Clang's libfuzzer to drive
+ the packet parsing code in ares_parse_*_reply, together with a
+ standalone wrapper for it (./aresfuzz) to allow use of afl-fuzz
+ for further fuzz testing.
+
+- test: Add local copy of GoogleMock/GoogleTest 1.7.0
+
+ Don't check in gtest/m4 files, as they are unused and interfere
+ with the top-level configure process.
+
+- doc: Show build badges in README.md
+
+ Note that these URLs will need to be updated if/when the test branch
+ gets pulled into the master repo/branch.
+

+
+- doc: Update in preparation for next release
+
+ Assume 1.11.0 is next (as there are various API additions).
+ Also add myself to AUTHORS.
+
+- build: Allow header compilation by Windows C++ compiler
+
+- build: Expose whether symbol hiding is on
+
+ Adding the CARES_SYMBOL_HIDING definition allows the test suite to
+ detect whether internal symbols are available or not.
+
+- build: Add autoconf macros for C++11 code using pthreads
+
+ Pull in testing macros from the GNU autoconf archive to allow
+ configure scripts to test for and setup use of a C++11 compiler
+ (AX_CXX_COMPILE_STDCXX_11) and the pthreads library (AX_PTHREAD).
+
+ Note that these macros are not used by the main library autoconf,
+ just by the tests (which share the same m4/ directory).
+
+- build: Add a code coverage option
+
+ Configure with:
+ ./configure --enable-code-coverage
+ Show coverage output with:
+ make code-coverage-capture
+
+ Built on m4/ax_code_coverage.m4 from the GNU autoconf archive
+ to provide the macros to check for presence of gcov + lcov;
+ upstream macro modified to:
+ - Remove use of $(AM_DEFAULT_VERBOSITY) , as earlier versions of
+ autoconf (such as the one used by default on Travis) do not have this.
+ - Rather than automatically defining CODE_COVERAGE_RULES to be a set
+ of makefile rules that use ifeq/endif (which is GNU make-specific),
+ instead only define CODE_COVERAGE_RULES if coverages is turned on,
+ and in that case don't use conditionals in the makefile.
+
+- api: Add entrypoints to allow use of per-server ports
+
+ Add user-visible entrypoints ares_{get,set}_servers_ports(3), which
+ take struct ares_addr_port_node rather than struct ares_addr_node.
+ This structure includes a UDP and TCP port number; if this is set
+ to zero, the channel-wide port values are used as before.
+
+ Similarly, add a new ares_set_servers_ports_csv(3) entrypoint, which
+ is analogous to ares_set_servers(3) except it doesn't ignore any
+ specified port information; instead, any per-server specified port
+ is used as both the UDP and TCP port for that server.
+
+ The internal struct ares_addr is extended to hold the UDP/TCP ports,
+ stored in network order, with the convention that a value of zero
+ indicates that the channel-wide UDP/TCP port should be used.
+
+ For the internal implementation of ares_dup(3), shift to use the
+ _ports() version of the get/set functions, so port information is
+ transferred correctly to the new channel.
+
+ Update manpages, and add missing ares_set_servers_csv to the lists
+ while we're at it
+
+- api: Add ares_set_sortlist(3) entrypoint
+
+ Allow explicit configuration of the channel's sortlist, by
+ specifying a string in the same format as the equivalent
+ /etc/resolv.conf option.
+
+ This allows library users to perform the same configuration
+ that is available via /etc/resolv.conf, but without needing
+ to change that file.
+
+- api: Allow injection of user-specified malloc/free functions
+
+ Add a new ares_library_init_mem() initialization function for the
+ library which allows the library user to specify their own malloc,
+ realloc & free equivalents for use library-wide.
+
+ Store these function pointers in library-wide global variables,
+ defaulting to libc's malloc(), realloc() and free().
+
+ Change all calls to malloc, realloc and free to use the function pointer
+ instead. Also ensure that ares_strdup() is always available
+ (even if the local environment includes strdup(3)), and change the
+ library code to always use it.
+
+ Convert calls to calloc() to use ares_malloc() + memset
+
+- api: Add option to expose some internal functions
+
+ Purely for testing, add --enable-expose-statics option to configure
+ which converts some static internal functions to be externally visible.
+
+- api: Expose the ares_library_initialized() function
+
+- ahost: Allow repeated -s <domain> options
+
+ This also removes a potential leak where later -s options would
+ replace earlier ones without freeing the relevant string.
+
+- Mark unhittable lines
+
+ Add comments for the benefit of the lcov tool, marking
+ lines that cannot be hit. Typically these are fall-back
+ protection arms that are already covered by earlier checks,
+ and so it's not worth taking out the unhittable code (in case
+ someone changes the code between the two places in future).
+
+- ares_set_servers_csv.3: make return type match code
+
+- bitncmp: update comment to match code behaviour
+
+- ares_striendstr: fix so non-NULL return can happen
+
+ This looks to have been broken since it was first introduced in 2005 in
+ commit aba0b775ea30 ("Added ares_getnameinfo which mimics the
+ getnameinfo API")
+
+- config_sortlist: free any existing sortlist on (re)alloc failure
+
+ If we get an allocation failure on 2nd or later entry in the sortlist, the
+ code would return ENOMEM but still leave the initial entries allocated.
+ Ensure that *sortlist is set to NULL whenever ENOMEM is returned.
+
+- ares_dup: clear new channel on failure
+
+ If the attempt to transfer IPv6 servers from the old to the new channel
+ fails, the previous code would still return a channel to the user even though
+ an error return code was generated. This makes it likely that users would
+ leak the channel, so explicitly clear the channel in this case.
+
+- ares_init_options: don't lose init failure
+
+ If (say) init_by_options() fails, the subsequent call to
+ init_by_defaults() was overwriting the return code with
+ success. Still call init_by_defaults() regardless, but track
+ its return value separately
+
+- ares_gethostbyname: don't leak valid-but-empty hostent
+
+ If an AF_UNSPEC query gets a valid response to its AAAA query,
+ but which has no IPv6 addresses in it, then the code chains on to
+ a A record query. However, the hostent from the AAAA response
+ was being leaked along the way (because it gets replaced before
+ the follow-on end_hquery() invocation).
+
+- ares_parse_txt_reply: propagate errors from per-substring loop
+
+ If we get an allocation failure when processing a particular substring in a
+ TXT record, that failure is silently lost; fix that by propagating errors from
+ the inner loop to the outer loop.
+
+- process_answer: fix things up correctly when removing EDNS option
+
+ When a server rejects an EDNS-equipped request, we retry without
+ the EDNS option. However, in TCP mode, the 2-byte length prefix was
+ being calculated wrong -- it was built from the answer length rather than
+ the length of the original request.
+
+ Also, it is theoretically possible that the call to realloc() might change
+ the data pointed to; to allow for this, qbuf also needs updating.
+
+ (Both these fixes were actually included in a patchset sent on the mailing
+ list in Oct 2012, but were included with other functional changes that
+ didn't get merged:
+ http://c-ares.haxx.se/mail/c-ares-archive-2012-10/0004.shtml)
+
+- ares__read_line: clear buf pointer on realloc failure
+
+- ares_expand_name: check for valid bits in label length
+
+ The top two bits of the label length indicate whether this is a
+ label length (00) or an index to a name elsewhere in the message
+ (11). RFC1035 4.1.4 says that the other possible values for the
+ top two bits (01, 10) are reserved for future use.

+Daniel Stenberg (30 Aug 2013)
+- [Tor Arntsen brought this change]
-* September 29
+ ares_rules.h: CARES_SIZEOF_LONG doesn't exist anymore, don't test for it
+
+ It was removed in f19387dd72432
-- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital
- when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for
- other OSes. He made c-ares check for and understand it if present.
+- nowarn: use <limits.h> instead of configure for size of long
+
+ This makes the header file much more multi-arch friendly and can be used
+ as-is with both 32 bit and 64 bit builds.
-- Now c-ares will use local host name lookup _before_ DNS resolving by default
- if nothing else is told.
+- timeoffset: made static and private
+
+ ares__timeoffset() was only used once within this single source file
-* September 26
+- timeadd: make static
+
+ ares__timeadd() was only ever used from within the same source
-- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf
- file to determine the sequence in which to search /etc/hosts and DNS. So on
- systems where this order is defined by /etc/host.conf instead of a "lookup"
- entry in /etc/resolv.conf, c-ares will always default to looking in DNS
- first, and /etc/hosts second.
+Yang Tse (18 Jul 2013)
+- xc-am-iface.m4: comments refinement
- c-ares now looks at
+- configure: fix 'subdir-objects' distclean related issue
+
+ See XC_AMEND_DISTCLEAN comments for details.
- 1) resolv.conf (for the "lookup" line);
- 2) nsswitch.fon (for the "hosts:" line);
- 3) host.conf (for the "order" line).
+- configure: automake 1.14 compatibility tweak (use XC_AUTOMAKE)
- First match wins.
+- xc-am-iface.m4: provide XC_AUTOMAKE macro
-- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is
- located in a static location. It assumed
- C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact,
- the location of the HOSTS file can be changed via a registry setting.
+Daniel Stenberg (12 May 2013)
+- gitignore: ignore all ares_*pdf but also CHANGES.dist
- There is a key called DatabasePath which specifies the path to the HOSTS
- file:
- http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx
+- bump: start working towards 1.10.1
- The patch will make c-ares correctly consult the registry for the location
- of this file.

+- Makefile.am: increment -version-info for 1.10.0 release
-- Made the lib get built static only if --enable-debug is used.
+- README: remove unnecessary comment
-- Gisle Vanem fixed:
+- ares_version.h: copyright end range year is now 2013
- Basically in loops like handle_errors(), 'query->next' was assigned a local
- variable and then query was referenced after the memory was freed by
- next_server(). I've changed that so next_server() and end_query() returns
- the next query. So callers should use this ret-value.
+- RELEASE-NOTES: synced with fb0737f3a0a1c37
- The next problem was that 'server->tcp_buffer_pos' had a random value at
- entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
+- [Paul Saab brought this change]
- I've also added a ares_writev() for Windows to streamline the code a bit
- more.
+ ares_parse_aaaa_reply: Plug memory leak
+
+ This change is similar to ares_parse_a_reply.c in commit
+ bffd67f16a8f42fe6dbf79ab2e39d92eea05c8a6
+
+- [Patrick Valsecchi brought this change]
-* July 20
-- Fixed a few variable return types for some system calls. Made configure
- check for ssize_t to make it possible to use that when receiving the send()
- error code. This is necessary to prevent compiler warnings on some systems.
+ ares_parse_txt_reply: return a ares_txt_reply node for each sub-string
+
+ Previously, the function would wrongly return all substrings merged into
+ one.
-- Made configure create config.h, and all source files now include setup.h that
- might include the proper config.h (or a handicrafted alternative).
+- [Alexander Klauer brought this change]
-- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
- use 'int' for that.
+ library init: documentation update
+
+ This commit updates the documentation of ares_library_init() and
+ ares_library_cleanup() with regard to the newly introduced reference
+ counting of initializations and deinitializations.
-- automake-ified and libool-ified c-ares. Now it builds libcares as a shared
- lib on most platforms if wanted. (This bloated the size of the release
- archive with another 200K!)
+- [Alexander Klauer brought this change]
-- Makefile.am now uses Makefile.inc for the c sources, h headers and man
- pages, to make it easier for other makefiles to use the exact same set of
- files.
+ library init: be recursive
+
+ Previously, a single call to ares_library_cleanup() would deinitialise
+ the c-ares library, regardless of how many times ares_library_init() was
+ called. This behaviour may cause problems in programs linking two or
+ more libraries which, in turn, use c-ares. The present commit fixes this
+ problem, deinitializing the library only after a number of calls to
+ ares_library_cleanup() matching the number of calls to
+ ares_library_init().
-- Adjusted 'maketgz' to use the new automake magic when building distribution
- archives.
+- [Patrick Valsecchi brought this change]
-- Anyone desires HTML and/or PDF versions of the man pages in the release
- archives?
+ protocol parsing: check input data stricter
+
+ ... so that bad length fields aren't blindly accepted
+
+ Bug: http://c-ares.haxx.se/mail/c-ares-archive-2013-04/0016.shtml
-* July 3
-- Günter Knauf made c-ares build and run on Novell Netware.
+Guenter Knauf (11 Apr 2013)
+- Create ares_build.h when buidling from Git.
-* July 1
-- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp
- fixes and made ares not use 'errno' to provide further info on Windows.
+- Added -DCARES_STATICLIB to CFLAGS.
+
+ Currently this static makefile does only support building the
+ static library libcares.a.
-* June 30
-- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.

+- [Alexander Klauer brought this change]
-* June 10
-- Gisle Vanem's init patch for Windows:
+ .gitignore: ignore patch files
+
+ This commit adds a line to .gitignore to the effect that patch files
+ generated by 'git format-patch' are excluded from the repository.
- The init_by_resolv_conf() function fetches the DNS-server(s)
- from a series of registry branches.
+- [Alexander Klauer brought this change]
- This can be wrong in the case where DHCP has assigned nameservers, but the
- user has overridden these servers with other prefered settings. Then it's
- wrong to use the DHCPNAMESERVER setting in registry.
+ ares_destroy() documentation: no new requests
+
+ Clarify that no new requests may be added to a resolver channel that is
+ currently being destroyed.
- In the case of no global DHCP-assigned or fixed servers, but DNS server(s)
- per adapter, one has to query the adapter branches. But how can c-ares know
- which adapter is valid for use? AFAICS it can't. There could be one adapter
- that is down (e.g. a VPN adapter).
+- [Alexander Klauer brought this change]
- So it's better to leave this to the IP Helper API (iphlapi) available in
- Win-98/2000 and later. My patch falls-back to the old way if not available.
+ Documentation: properly document ARES_ECANCELLED
+
+ This commit clarifies the behaviour of ares_cancel() with respect to
+ callbacks and adds missing documentation of ARES_ECANCELLED to the man
+ pages of the affected functions.
-* June 8
-- James Bursa fixed an init issue for RISC OS.
+- [Alexander Klauer brought this change]
-* May 11
-- Nico Stappenbelt reported that when processing domain and search lines in
- the resolv.conf file, the first entry encountered is processed and used as
- the search list. According to the manual pages for both Linux, Solaris and
- Tru64, the last entry of either a domain or a search field is used.
+ ares_cancel(): cancel requests safely
+
+ An invocation of ares_cancel() walks through the request list, calling
+ the callbacks of all pending requests on a channel. Previously, if such
+ a callback added a new request to the channel, the request list might
+ not end up empty, causing an abort by assertion failure. The present
+ commit ensures that precisely all requests present upon entry of
+ ares_cancel() are cancelled, and that adding new requests through
+ callbacks is safe.
- This is now adjusted in the code
+Yang Tse (10 Mar 2013)
+- ares.h: stricter CARES_EXTERN linkage decorations logic
+
+ No API change involved.
-Version 1.2.0 (April 13, 2004)
+- ares_build.h.dist: enhance non-configure GCC ABI detection logic
+
+ GCC specific adjustments:
+
+ - check __ILP32__ before 32 and 64bit processor architectures in
+ order to detect ILP32 programming model on 64 bit processors
+ which, of course, also support LP64 programming model, when using
+ gcc 4.7 or newer.
+
+ - keep 32bit processor architecture checks in order to support gcc
+ versions older than 4.7 which don't define __ILP32__
+
+ - check __LP64__ for gcc 3.3 and newer, while keeping 64bit processor
+ architecture checks for older versions which don't define __LP64__
-* April 2, 2004

+- zz40-xc-ovr.m4: check another three basic utilities
-* April 1, 2004
-- Dirk Manske provided a new function that is now named ares_cancel(). It is
- used to cancel/cleanup a resolve/request made using ares functions on the
- given ares channel. It does not destroy/kill the ares channel itself.
+- zz40-xc-ovr.m4: 1.0 interface stabilization
+
+ - Stabilization results in 4 public interface m4 macros:
+ XC_CONFIGURE_PREAMBLE
+ XC_CONFIGURE_PREAMBLE_VER_MAJOR
+ XC_CONFIGURE_PREAMBLE_VER_MINOR
+ XC_CHECK_PATH_SEPARATOR
+ - Avoid one level of internal indirection
+ - Update comments
+ - Drop XC_OVR_ZZ40 macro
+
+- zz40-xc-ovr.m4: emit witness message in configure BODY
+
+ This avoids witness message in output when running configure --help,
+ while sending the message to config.log for other configure runs.
+
+- zz40-xc-ovr.m4: truly do version conditional overriding
+
+ - version conditional overriding
+ - catch unexpanded XC macros
+ - fix double words in comments

+- zz40-xc-ovr.m4: reinstate strict AC_REQUIRE macro dependencies
+
+- zz40-xc-ovr.m4: avoid double single-quote usage
+
+- zz40-xc-ovr.m4: parentheses balancing of 'case' statements
+
+ m4 quadrigraph shell comment technique allows proper autoconf
+ parentheses balancing in shell 'case' statements. The presence
+ of unbalanced parentheses may otherwise trigger expansion bugs.
+
+- zz40-xc-ovr.m4: internals overhauling
+
+ - Update comments
+ - Execute commands in subshells
+ - Faster path separator check
+ - Fix missing 'test' command
+ - Rename private macros
+ - Minimize AC_REQUIRE usage
+
+- zz40-xc-ovr.m4: redirect errors and warnings to stderr
+
+- configure: use XC_CONFIGURE_PREAMBLE early checks
+
+ Some basic checks we make were placed early enough in generated
+ configure script when using autoconf 2.5X versions. Newer autoconf
+ versions expand these checks much further into the configure script,
+ rendering them useless. Using XC_CONFIGURE_PREAMBLE fixes placement
+ of early intended checks across all our autoconf supported versions.
+
+- zz40-xc-ovr.m4: provide XC_CONFIGURE_PREAMBLE macro
+
+- configure: autotools compatibility fixes - step I
+
+ Fix proper macro expansion order across autotools versions for

+- ares_private.h: use again memdebug.h instead of curl_memdebug.h
+
+- configure.ac: replace AM_CONFIG_HEADER with AC_CONFIG_HEADERS
+
+ automake 1.13 errors if AM_CONFIG_HEADER is used in configure script.
+
+- cares-override.m4: provide AC_CONFIG_MACRO_DIR definition conditionally
+
+ Provide a 'traceable' AC_CONFIG_MACRO_DIR definition only when using
+ an autoconf version that does not provide it, instead of what we were
+ doing up to now of providing and overriding AC_CONFIG_MACRO_DIR for
+ all autoconf versions.
+
+- ares_private.h: use curl_memdebug.h instead of memdebug.h
+
+- vc6cares.dsp: add ares_create_query.c and ares_parse_soa_reply.c
+
+- cares-functions.m4: improve gethostname arg 2 data type check

+- configure: check if compiler halts on function prototype mismatch
+
+- cares-functions.m4: add gethostname arg 2 data type check and definition
+
+- cares-functions.m4: update thread-safeness detection of getaddrinfo()
+
+ Take in account that POSIX standard Issue 7 drops h_errno support. Now, we also
+ consider getaddrinfo() to be thread-safe when (_POSIX_C_SOURCE >= 200809L) or
+ (_XOPEN_SOURCE >= 700) independently of whether h_errno exists or not.
+
+ Take in account that h_errno might be a modifiable lvalue not defined as
+ a C preprocessor macro.
+
+- setup_once.h: HP-UX <sys/socket.h> issue workaround
+
+ Issue: When building a 32bit target with large file support HP-UX
+ <sys/socket.h> header file may simultaneously provide two different
+ sets of declarations for sendfile and sendpath functions, one with
+ static and another with external linkage. Given that we do not use
+ mentioned functions we really don't care which linkage is the
+ appropriate one, but on the other hand, the double declaration emmits
+ warnings when using the HP-UX compiler and errors when using modern
+ gcc versions resulting in fatal compilation errors.
+
+ Mentioned issue is now fixed as long as we don't use sendfile nor
+ sendpath functions.

+ target to be consistent with e.g. Makefile.msvc etc.
+ * 'ENABLE_IPV6' is no longer used. Hence removed the '%use_ipv6' construct.
+ * object-file order seems to be important (Watcom v.19). Hence

+- ares_reinit()
+
+ - To allow an app to force a re-read of /etc/resolv.conf etc, pretty much
+ like the res_init() resolver function offers
+
+- - Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't
+ check for broken connections like ares_process() did. Based on that, I
+ merged the two functions into a single generic one with two front-ends.
+
+Yang Tse (30 Dec 2009)

+
+ - Compiler option /GX is now replaced with equivalent /EHsc for all versions.
+
+- - Ingmar Runge noticed that Windows config-win32.h configuration file
+ did not include a definition for HAVE_CLOSESOCKET which resulted in
+ function close() being inappropriately used to close sockets.
+
+Daniel Stenberg (30 Nov 2009)
+- start working on 1.7.1
+
+Version 1.7.0 (27 Nov 2009)
+
+Yang Tse (27 Nov 2009)
+- Preserve empty line following last target
+
+- - Larry Lansing fixed ares_parse_srv_reply to properly parse replies
+ which might contain non-SRV answers, skipping over potential non-SRV
+ ones such as CNAMEs.
+
+- When using icc, compile with -fpic and link with intel dynamic libraries.
+
+- Added 'currently' in italics to insist on transient situation.
+
+- Fix language
+
+- Daniel wants upcoming release to be 1.7.0
+
+- Mention last changes
+
+- - Removed from external interface preprocessor symbol definition for
+ CARES_HAVE_ARES_FREE_DATA. Current functionality of ares_free_data()
+ makes it unnecessary.
+
+- Added README.msvc
+
+- Changed c-ares naming conventions when using MSVC as described in README.msvc
+
+- - Mention other recent changes
+
+- - Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and
+ ares_addr6ttl in order to prevent name space pollution, along with
+ necessary changes to code base and man pages.This change does not break
+ ABI, there is no need to recompile existing applications. But existing
+ applications using these structs with the old name will need source code
+ adjustments when recompiled using c-ares 1.6.1.
+
+- - Jakub Hrozek fixed more function prototypes in man pages to sync them
+ with the ones declared in ares.h
+
+- Make configure remove the ares_build.h file included in distribution tarballs.
+
+- Fix macro redefinition.
+
+- Fix name space pollution.
+
+- Allow using different extra import libraries for debug and release builds.
+
+- Add manifest stuff to msvc makefile
+
+- Sync man page with reality
+
+- Add missing external API decoration for ares_set_socket_callback()
+
+- Add ares_free_data() man page.
+
+- - Provide in external interface preprocessor symbol definitions for
+ CARES_HAVE_ARES_FREE_DATA as an indication of function availability.
+
+- Remove typecast
+
+- Fix comment
+
+- Add ares_data.c and ares_data.h
+
+- Jakub Hrozek modified ares_parse_srv_reply() and ares_parse_txt_reply() API
+ to return a linked lists of results. These were also modified to internally
+ use the ares_data memory struct and as such its result must be free'ed with
+ ares_free_data().
+
+- Initial support for the generic ares_free_data() function that will allow
+ applications to free memory allocated and returned by some c-ares funtions.
+
+- Make usage of calloc()'s arguments consistent with rest of code base
+
+- workaround icc 9.1 optimizer issue
+
+- Add icc fvisibility bug test
+
+- Fix icc 9.0 compiler warning: external definition with no prior declaration
+
+- Fix three var names
+
+- Add check for assert.h header file
+
+- getaddrinfo is fully thread safe on solaris versions which
+ implement the function even when h_errno is not a macro.
+
+ The h_errno macro test now only done on systems for which there
+ is no hard coded knowledge about getaddrinfo's thread safeness.
+
+- Remove files generated on previous buildconf/configure run
+
+- Remove enable-thread / disable-thread configure option. These were only placebo
+ options. The library is always built as thread safe as possible on every system.
+
+- Refactor how preprocessor symbol _THREAD_SAFE definition is done.
+
+- Assume that getaddrinfo is thread safe, unless hard coded
+ knowledge says the contrary or h_errno is not defined.
+
+- Related with the threadsafe capability of getaddrinfo:
+
+ - Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2
+ and newer have a threadsafe getaddrinfo.
+
+ - Fix Dragonfly BSD triplet detection.
+
+ - In case the hard-coded knowledge says that getaddrinfo is threadsafe,
+ an additional check is done to verify that h_errno is also defined.
+ If h_errno isn't defined, we finally assume that it isn't threadsafe.
+ Jamie Lokier provided the inspiration for this extra check.
+
+- AIX 5.2 and newer have threadsafe getaddrinfo.
+
+ Add some comments to better understand what the regex's pretend to achieve.
+
+- HP-UX 11.11 and later have threadsafe getaddrinfo
+
+- Check if getaddrinfo is threadsafe when function check allows it to be used
+
+- Renamed fpGetNetworkParams and fpSystemFunction036 to avoid namespace pollution with static library
+
+- Add kernel32.lib
+
+- Mention last changes
+
+- Reinstate copyright symbol lost in previous commit
+
+- Make some strings different in resource file for debug or release builds
+
+- Ignore more subdirs
+
+- Fix compiler warning: conditional expression is constant
+
+- Sync linker and resource compiler options with Makefile.msvc
+
+- Follow Makefile.msvc subdirectory naming scheme, and sync compiler options
+
+- Updated MSVC makefile that allows building dynamic and static
+ c-ares libraries in debug and release flavours.
+
+ Additionally each of the three sample programs is built against
+ each of the four possible c-ares libraries, generating all this
+ a total number of 12 executables and 4 libraries.
+
+- Test for USE_WINSOCK since it is more restrictive than WIN32
+
+- Make header inclusion depend on HAVE_*_H definition
+
+- Remove unneeded preprocessor directives
+
+- Adjust c-ares include paths for memory tracking enabled (--enable-curldebug) builds
+
+- source files used by sample programs
+
+- Renamed c-ares setup.h to ares_setup.h
+
+- Adjust include paths to take in account that currently:
+
+ c-ares with --enable-curldebug uses memdebug.h from libcurl's lib subdirectory.
+
+ memdebug.h needs access to libcurl's setup.h from libcurl's lib subdirectory
+ and also needs access to libcurl's generated curl_config.h
+
+- Undo old temporary change once used for testing purposes
+
+- Mention many changes
+
+- Mention --enable-symbol-hiding configure option
+
+- Symbol hiding configure options renamed to the hopefully less ambiguous
+ --enable-symbol-hiding and --disable-symbol-hiding as well as related
+ macro names and some internal variables used for them.
+
+ Related configuration file preprocessor symbols named to
+ CARES_SYMBOL_HIDING and CARES_SYMBOL_SCOPE_EXTERN.
+
+- Header inclusion depending on HAVE_* symbol.
+ Fix two typos.
+
+- Comparison of the Initial revision of this file with ares_parse_a_reply.c
+ shows that this one is actually a modified copy of ares_parse_a_reply.c.
+
+ In order to comply with ares_parse_a_reply.c's M.I.T. license, the old
+ 1998 M.I.T. copyright notice is now also preserved in this file the same
+ as it is done in other ares_parse_*.c files.
+
+- Add CVS Id tag.
+ Fix identation of some license lines.
+
+- Add CVS Id tag.
+
+- Fix comment
+
+- In no particular order, changed/fixed all of the following in
+ ares_parse_txt_reply() current version:

+ - Fixed a couple of potential double free's.
+
+ - Fixed memory leaks upon out of memory condition.
+
+ - Fixed pointer arithmetic.
+
+ - Setting ntxtreply to zero upon entry for all failure cases.
+
+ - Changed data type to size_t for variables substr_len, str_len and
+ the length member of ares_txt_reply struct.
+
+ - Avoided a couple of memcpy() calls.
+
+ - Changed i data type to unsigned int to prevent compiler warnings.
+
+ - Adjusted a comment.
+
+ - Use ARES_SUCCESS literal for successfull completion.
+
+ - Added CVS Id tag.
+
+- Add c-ares DLL resource file to distribution archive
+
+- ignore files
+
+- Empty subdir
+
+- Updated MSVC 6.0 workspace and project files that allows building
+ dynamic and static c-ares libraries in debug and release flavours.
+
+ Additionally each of the three sample programs is built against
+ each of the four possible c-ares libraries, generating all this
+ a total number of 12 executables and 4 libraries.
+
+Daniel Stenberg (29 Oct 2009)
+- no need to check for NULL pointers before dereferencing, as the pointers
+ MUST be valid and they are dereferenced further down in the function
+ unconditionally!
+
+- shorten the descriptions somewhat
+
+- update to the new struct name
+
+- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing
+
+- use 'ares_srv_reply' for proper name-spacing

+- Add reference for ares_parse_srv_reply.pdf
+
+- Add reference for ares_parse_srv_reply docs
+
+- External API function linkage decoration adjustment
+
+- External API function linkage decoration adjustment
+
+- Initial step towards the ability to reduce c-ares exported symbols
+ based on the 'visibility' attribute for GNUC and __global for Sun
+ compilers, taking also in account __declspec function decoration
+ for Win32 and Symbian DLL's.
+
+ Introducing configure options --enable-hidden-symbols and
+ --disable-hidden-symbols following libcurl's naming.
+
+- Fix comment
+
+- Fix spelling
+
+- Fix Pelles C Win32 target compilation issues
+
+- John Engelhart noticed an unreleased problem relative to a duplicate
+ ARES_ECANCELLED error code value and missing error code description.
+
+- Fix compiler warning: local variable may be used without having been initialized
+
+- Use *_CHECK_PATH_SEPARATOR_REQUIRED to ensure that *_CHECK_PATH_SEPARATOR
+ is only expanded and included once in the configure script.
+
+- Our _AS_PATH_SEPARATOR_PREPARE override is now m4_defun'd instead of m4_define'd
+ due to autoconf 2.64 m4_require'ing it in _AS_SHELL_SANITIZE indirectly through
+ _AS_PATH_WALK.
+
+- Fix compiler warning: argument is incompatible with corresponding format string conversion
+
+- Fix potential out-of-bounds read
+
+- Fix compiler warning: loop without body
+
+- Fix compiler warning
+
+- Fix compiler warning
+
+- Fix compiler warning
+
+- Fix compiler warning: addition result could be truncated before cast to bigger sized type
+
+- Overhauled ares__get_hostent()
+
+ - Fixing out of bounds memory overwrite triggered with malformed /etc/hosts file.
+ - Improving parsing of /etc/hosts file.
+ - Validating requested address family.
+ - Ensuring that failures always return a NULL pointer.
+ - Adjusting header inclusions.
+
+- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak
+
+- more files to ignore
+
+- Check if _REENTRANT definition is required to
+ make errno available as a preprocessor macro.
+
+- Attempt to silence bogus compiler warning: "Potential null pointer dereference"
+
+- ignore more files
+
+Gisle Vanem (7 Sep 2009)

+
+- Update email address.
+
+- Update my email address. Add ares_config.h as dependency for 'make depend'.
+
+Yang Tse (6 Sep 2009)
+- T_SRV portability check
+
+Gunter Knauf (5 Sep 2009)
+- changed includes to match style how we do with all other *.c files.
+
+- changed u_int16_t to unsigned short because it is the only place within ares and curl where such a type would be used;
+ also it broke many autobuilds. We should probably introduce an ares_port_t if we want to use a type here.
+
+Gisle Vanem (5 Sep 2009)
+- Replace 'uint16_t' with 'u_int16_t' since the latter is used in ares.h.
+
+- Added 'ares_parse_srv_reply.obj'. Added definition of 'u_int16_t'. This is I don't like; we should not depend on such non-universal types in a public header. But this is just a quick fix.
+
+Daniel Stenberg (4 Sep 2009)
+- - Jakub Hrozek added ares_parse_srv_reply() for SRV parsing
+
+Steinar H. Gunderson (27 Aug 2009)
+- Support lookup of IPv4 literals in ares_gethostbyname(), even when the address family is set to AF_INET6.
+
+Gisle Vanem (3 Aug 2009)
+- Remove call to LoadLibrary(). (leftover from debugging).
+
+- Fix bad sentence.
+
+Daniel Stenberg (3 Aug 2009)
+- - Timo Teras changed the reason code used in the resolve callback done when
+ ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
+ better allow the callback to know what's happening.
+
+- - Joshua Kwan fixed the init routine to fill in the defaults for stuff that
+ fails to get inited by other means. This fixes a case of when the c-ares
+ init fails when internet access is fone.
+
+Gunter Knauf (16 Jul 2009)
+- test if adding ../lib to includes can fix the current break ...
+
+- renamed generated config.h to ares_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h.
+
+Yang Tse (21 Jun 2009)
+- Refactor how libraries are checked for connect() function, follow-up.
+
+- Refactor how libraries are checked for connect() function,
+ and check for connect() as it is done for other functions.
+
+Gisle Vanem (20 Jun 2009)
+- Remove unneeded defines.
+
+- Use select_s() and not select().
+
+Yang Tse (19 Jun 2009)
+- sclose() function-like macro definition used to close a socket,
+ now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
+ config file preprocessor definitions.
+
+- add CloseSocket camel case function check
+
+- check for socket() and closesocket() as it is done for other functions
+
+- Remove HAVE_CONFIG_H definition from here,
+ CFLAGS from common.dj already defines it.
+
+- initial step towards decoupling c-ares from libcurl for DOS
+
+- don't ignore these subdirs, they must be removed first
+
+- Remove DEBUGBUILD symbol definition, is not required for programs using the library.
+
+- DEBUGBUILD symbol definition for debug builds
+
+- ignore some subdirs
+
+- fix comment
+
+- Try to make more clear that --enable-curldebug has nothing to do with --enable-debug for this library.
+
+- Revert last change, it is inappropriate.
+
+Gisle Vanem (12 Jun 2009)
+- Replace CURLDEBUG with DEBUGBUILD.
+
+Yang Tse (11 Jun 2009)
+- when running automake copy missing files instead of symlinking them
+
+- Adjusted to take in account that...
+
+ With the curl memory tracking feature decoupled from the debug build feature,
+ CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:
+
+ CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)
+
+ DEBUGBUILD used for debug enabled specific code (--enable-debug)
+
+- c-ares' --enable-debug --enable-curldebug decoupling follow-up
+
+- mention last changes
+
+- Remove buildconf.bat from release and daily snapshot archives.
+
+ buildconf.bat is only for CVS tree builds.
+
+- Ensure that buildconf.bat does nothing unless it is used with a CVS checkout.
+
+- CVS-INFO file only present in CVS tree, never in release nor daily snapshot
+ archives. Used as a sentinel file in buildconf.bat to differentiate CVS builds.
+
+Gisle Vanem (8 Jun 2009)
+- Update comment about "ML". Removed "-D_USE_32BIT_TIME_T" (not a requirement).
+
+Yang Tse (8 Jun 2009)
+- just comment it out
+
+- For debugging purposes...
+
+ Disable the '-export-symbols-regex' to discard this as the origin
+ of link failures related with shared libraries and non-GNU linkers.
+
+- c-ares Makefile.am back to using $(top_builddir) for *_LDADD
+
+- c-ares' -no-undefined and --enable-curldebug adjustments
+
+- Use relative path to built c-ares tree libtool library
+
+- John E. Malmberg noticed that the configure script was failing to detect the
+ timeval struct on VMS when building with _XOPEN_SOURCE_EXTENDED undefined due
+ to definition taking place in socket.h instead of time.h
+
+- Fix compiler warning: out of bound access
