+- 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.
+
+- test: Force reinstall of libtool on OSX
+
+ Travis build environment appears to have changed.
+
+- test: Add valgrind build variant
+
+- test: Add null pointer to gtest args
+
+ GoogleTest assumes that there is a null pointer in argv[argc],
+ so make it look like that. Without this change, tests run with
+ command-line arguments get memory errors under valgrind/ASAN.

+- AUTHOR: maybe gitgub isn't really an author =)
+
+- AUTHORS: added contributors from the git log
+
+- LICENSE.md: add a stand-alone license file
+
+ Just the MIT license used in the top the source files moved out to a
+ stand-alone file for easier reference and discovery.
+
+- README: added "CII best practices" badge
+
+- SECURITY.md: suggested "security process" for the project
+
+David Drysdale (17 Aug 2016)
+- test: Add Clang static analysis build to Travis
+
+ Run scan-build over the library source code, but skip the
+ tests. Needs a later Clang install in Travis
+
+- test: more info on how to run fuzz testing
+
+- test: make fuzzer driver code C not C++
+
+- test: fuzzer mode for AFL's persistent mode
+
+ When fuzzing with AFL, if the LLVM-based instrumentation is
+ used (via the afl-clang-fast wrapper), then it is possible to
+ have a single execution of the fuzzer program iterate multiple
+ 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++
+
+- test: disable MinGW tests
+
+ The test binary built in the MinGW build is failing for some
+ reason. It works for me when I build locally, so I'm guessing
+ it's down to some sort of AppVeyor environment issue.
+
+ Disable for now.
+
+Daniel Stenberg (16 Aug 2016)
+- read_tcp_data: remove superfluous NULL check
+
+ CID 56884 by Coverity. The pointer is already derefenced before this
+ point so it can't be NULL here anyway.

+- test: Run fuzzcheck.sh in Travis build
+
+- test: add fuzzing check script to tests
+
+ Add a test script that runs the fuzzing command over the
+ corpus of DNS packets. This doesn't actually do any fuzzing
+ (it just runs them as inputs without generating any variations)
+ but it does ensure that the fuzzing entrypoint is still working.
+
+- test: allow multiple files in aresfuzz command line
+
+ If no arguments are specified, use stdin as input.
+ Otherwise treat each argument as a filename and feed
+ its contents to the fuzz entrypoint.
+
+- test: Add corpus of DNS packets
+
+ For fuzz testing it is useful to start from a corpus of valid
+ packets, so fill out the test/fuzzinput/ directory with a bunch
+ of inputs.
+
+ These packets were generated by temporarily modifying the c-ares
+ process_answer() function to save off any incoming response messages.
+
+- test: Add utility to show DNS packet from file

+ Fix nsort initialization
+
+ Author: Alexander Drachevskiy
+ http://c-ares.haxx.se/mail/c-ares-archive-2014-07/0004.shtml
+ http://c-ares.haxx.se/mail/c-ares-archive-2014-07/0014.shtml
+
+- test: Check setting nsort=0 option is respected
+
+- test: Update fuzzing function prototype
+
+ libFuzzer changed expected return type from void to int
+ in LLVM 3.8.
+
+- Explicitly clear struct servent before use
+
+ On a build where MSAN has been manually set up (which involves
+ using an MSAN-instrumented version of the standard C++ library, see
+ https://github.com/google/sanitizers/wiki/MemorySanitizerLibcxxHowTo)
+ there's a warning about use of uninitialized memory here. It
+ might be a false positive, but the fix is trivial so include it.
+
+- test: for AF_UNSPEC, return CNAME only for AAAA, but valid A record
+
+ Also shuffle expected responses rsp6/rsp4 into the order they will occur.
+
+- [Chris Araman brought this change]
+
+ msvc_ver.inc: support Visual Studio 2015 Update 1
+
+- build: commonize MSVC version detection
+
+ Remove the need to copy/paste version number mapping between
+ Makefile.msvc and test/Makefile.msvc.
+
+- test: Use different name in live test
+
+- test: Only pass unused args to GoogleTest
+
+- ahost.c: add cast to fix C++ compile
+
+ If ahost.c is force-compiled as C++ the missing cast from
+ (void *) to (char **) is problematic.
+
+- ares_library_cleanup: reset ares_realloc too
+
+ Otherwise a subsequent use of the library might use a previous
+ incarnation's realloc() implementation.
+
+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.

+- ares_dup.3: remove mention of nonexistent function
+
+ ares_dup_options() doesn't exist, so don't document it.
+
+- test: skip repeated build steps
+
+ Top-level buildconf/configure now triggers for the

+
+- test: namespaces unavailable when cross-compiling

+Daniel Stenberg (13 Feb 2016)
+- configure: only run configure in test when NOT cross-compiling
+
+ ... as the tests won't run cross-compiled anyway
+
+David Drysdale (13 Feb 2016)
+- test: prefer ON_CALL to EXPECT_CALL to reduce flakes
+
+ For UDP tests, there's a chance of a retry. EXPECT_CALL only
+ expects a single request to arrive at the server; ON_CALL allows
+ for a UDP retry and repeats the same answer.
+
+ Note that ON_CALL and EXPECT_CALL can't be mixed in the same
+ test, and that tests that have a varied sequence of responses
+ for the same repeated request still have to use EXPECT_CALL.
+
+Daniel Stenberg (13 Feb 2016)
+- configure: run configure in 'test' too

+
+ Closes #17
+
+David Drysdale (11 Feb 2016)
+- Use "resolve" as synonym of "dns" in nsswitch.conf
+
+ Modern Linux systems may have libnss_resolve from systemd as the
+ resolver, which is then configured in /etc/nsswitch.conf with
+ the "resolve" keyword rather than "dns".
+
+ Fixes #33
+
+- ares_set_socket_callback: make manpage match code
+
+ The code in ares_process.c that invokes the socket creation/connection
+ callback only checks for rc < 0, not for standard ares error codes.
+
+- Merge pull request #36 from AGWA-forks/master
+
+ Add ares_set_socket_configure_callback()
+
+- test: Update init tests to match behaviour
+
+ Unreadable config files are now treated the same way
+ as absent config files.
+
+- [Fedor Indutny brought this change]
+
+ Ignore `fopen` errors to use default values
+
+ After 46bb820be3a83520e70e6c5f0c5133253fcd69cd `init_by_resolv_conf`
+ 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
+ default value.
+
+Andrew Ayer (9 Feb 2016)
+- Document callback type in man page for ares_set_socket_callback
+
+- Add ares_set_socket_configure_callback()
+
+ This function sets a callback that is invoked after the socket is
+ created, but before the connection is established. This is an ideal
+ time to customize various socket options.

+
+ txt: introduce `ares_parse_txt_reply_ext`
+
+ Introduce `ares_txt_ext` structure with an extra `record_start`
+ field, which indicates a start of a new TXT record, thus allowing to
+ differentiate the chunks in the same record, from a chunks in a
+ different record.
+
+ Introduce a new API method: `ares_parse_txt_reply_ext` that works with
+ this kind of struct.

+
+- doc: update badge locations to master repo
+
+- test: Enable maintainer mode + debug in Travis
+
+- test: Add an iOS build target
+
+- 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()
+ - Set TCP_NODELAY for mock server
+ - Turn on tests in AppVeyor build
+
+- test: Disable tests that manipulate env on Windows
+
+- test: Move file lists into Makefile.inc
+
+ In preparation for a Win32 build of the test suite.
+
+- test: Add a simple multi-server test
+
+ Check rotate option does something
+
+- 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
+
+ Ports are significant in the _ports_ variant functions, so update test to cope.
+
+- test: Make GetNameServers() utility function port-aware
+
+ Also make it generally available.
+
+- test: more testing, including of internal static functions
+
+- test: more tests, especially fallback processing
+
+ - Make mock server listen on UDP + TCP in parallel.
+ - Test UDP->TCP fallback on truncation
+ - Test EDNS->no-EDNS fallback
+ - Test some environment init options
+ - Test nonsense reply
+
+ test: short response
+
+- test: more tests, particularly of initialization
+
+- test: Run mock tests over both TCP and UDP
+
+ With the exception of a few tests that make use of the timed
+ retry aspect of UDP.
+
+- test: Run mock tests over both IPv4 and IPv6
+
+- test: Add more tests for edge cases
+
+- test: more nooks and crannies of pton functions
+
+- test: More tests for PTR parsing

+- test: More parsing tests
+
+ Including:
+ - Split each parse function test set out into separate files.
+ - Add an allocation failure test for each parsing function.
+ - Add error check test for each parsing function.
+
+- test: Add various additional tests
+
+- test: More tests
+
+ Include tests of internal functions, based on the value of the

+ - 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.

+
+- 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.

+
+ Some basic checks we make were placed early enough in generated

+- 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.
+

+- ares_inet_ntop: reapply changes from previous c-ares version (III)
+
+ - Replace 'u_char' with 'unsigned char'.
+ - Replace 'u_int' with 'unsigned int'.
+ - use macros ERRNO and SET_ERRNO() for errno handling.
+
+- ares_inet_ntop: reapply changes from previous c-ares version (II)
+
+ - Remove rcsid.
+ - Adjust header file inclusions.
+ - ares_inet_ntop used only on systems without a proper inet_ntop function.
+
+- ares_inet_ntop: reapply changes from previous c-ares version (I)
+
+ - Replace tabs with spaces.
+ - Use ANSI C style for function declarations and definitions.
+ - Use sizeof with parentheses.
+
+- ares_inet_ntop: fix off by one error triggering out of bounds write
+
+ ares_inet_ntop would trigger an out of bounds write when the representation
+ of the address required 15 characters, due to not taking in account null
+ termination character.
+
+ Full import of inet_ntop.c from bind-9.5.3rc1 to pull additional fixes.
+
+- ares_nowarn: add conditional inclusion of assert.h header
+
+- fix compiler warning: conversion may lose significant bits
+
+- ares_inet_net_pton: fix non-rejection of some malformed literals
+
+ ares_inet_net_pton would return wrong values when excessively large,
+ and invalid, netmasks are used. Fixes are from bind-9.5.3rc1,
+ issue also described in the WLB-2008080064 advisory.
+
+- setup_once: provide ISASCII macro
+
+- configure: inet_net_pton function check adjustments
+
+ Define HAVE_INET_NET_PTON only when system's inet_net_pton function is IPv6
+ capable and is not affected by the WLB-2008080064 advisory.
+
+ HAVE_INET_NET_PTON_IPV6 is no longer defined nor used.
+
+- ares_init: fix detection of semicolon comments in resolv.conf
+
+ File resolv.conf may either use a hash '#' or a semicolon ';' character as an
+ indication that the rest of the line is a comment. This fixes not recognizing
+ the semicolon as a valid comment indicator in resolv.conf.

+
+Yang Tse (1 Dec 2010)
+- fix compiler warning: conversion may lose significant bits
+
+- atoi: remove atoi usage
+
+- ares_init: fix compiler warning: conversion may lose significant bits
+
+- configure: fix autoconf warning
+
+- inet_pton: fix compiler warning
+
+- configure: use autobuilds to temporarily verify strict aliasing warnings.
+
+ Temporarily, When cross-compiling with gcc 3.0 or later, enable strict aliasing
+ rules and warnings. Given that cross-compiled targets autobuilds do not run the
+ test-suite, there is no risk of running code that violates strict aliasing rules
+
+- ares_getnameinfo: Partially revert commit 85520d66e0ac7ac73411bc25e98769a88b2f
+
+ Upon socket address family and length validation failure return ARES_ENOTIMP
+ in callback again, this is the error code documented in man page and used
+ mostly all over the library.
+
+- ares_getnameinfo: Validate socket address family and length.
+
+ Validate socket address family and that the socket address length is appropriate
+ for the specified family. Failure is reported with ARES_EBADFAMILY in callback.
+
+- ares_getnameinfo: fix two compiler warnings
+
+- Added another VS10 version string
+
+- Fix GCC 4 compiler warning 'dereferencing type-punned pointer might break strict-aliasing rules'.
+
+- Revert commit 494274e653936335c255a47599970de3df21e7c4
+
+- configure: fix autoconf 2.68 warning: no AC_LANG_SOURCE call detected in body
+
+- Fix compiler warning: array subscript has type 'char'
+
+- Fix GCC 4 compiler warning 'dereferencing type-punned pointer might break strict-aliasing rules'.
+
+- Revert following commits:
+ 07bc7ea79509bcc9ef6e09151e81766ed00d3392
+ 3392a50ea3f8573ea4b7a9d82b9833dab60cb0e9
+ 9912637d32c9987719a1ea12db591aee2941891c
+
+ The purpose of the whole patch was to silence a compiler warning triggered
+ with GCC 4 on file ares_process.c The specific compiler warning was
+ 'dereferencing type-punned pointer might break strict-aliasing rules'.
+
+ A simpler patch will follow to equally silence the warning.
+
+- ares_options: reorder header inclusions to make inclusion of
+ ares_private.h the last included one again.

+
+ adig: fix NAPTR parsing
+
+ I ran across a small "issue" in your adig example.
+
+ It is simply the last part of the NAPTR record, the replacement element,
+ which is not a string, as currently handled in adig, but a domain name.
+
+- ares_save_options: assignments instead of memcpy
+
+- init_by_options: don't copy an empty sortlist
+
+ If there aren't any sort items to copy, don't bother. Without this
+ little precaution it would do a malloc(0) which causes undefined
+ behaviors and is frowned upon by curl's memdebug-system.

+- [Mike Crowe brought this change]
+
+ Fix lookup with HOSTALIASES set.
+
+ ares__read_line returns ARES_EOF when it reaches the end of the
+ file. This will happen every time when reading to the end of the
+ HOSTALIASES file. Unfortunately single_domain treats this error as
+ being fatal.

+- 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

+- 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.

+ better allow the callback to know what's happening.
+
+- - Joshua Kwan fixed the init routine to fill in the defaults for stuff that

+- * February 3 2009 (Phil Blundell)
+ - If the server returns garbage or nothing at all in response to an AAAA query,
+ go on and ask for A records anyway.
+
+Daniel Stenberg (31 Jan 2009)
+- - ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving
+ either AF_INET6 or AF_INET. It works by accepting any of the looksups in the
+ hosts file, and it resolves the AAAA field with a fallback to A.
+
+Gisle Vanem (18 Jan 2009)
+- fopen() returns error in 'errno' even on Windows.
+ So don't use ERRNO (GetLastError()). Trimmed trailing
+ blanks.
+
+- Constified some arguments in local functions.
+
+Daniel Stenberg (14 Jan 2009)
+- - ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it
+ now declares the private struct ares_in6_addr for all systems instead of
+ relying on one possibly not present in the system.
+
+Phil Blundell (13 Jan 2009)
+- - ares__send_query() now varies the retry timeout pseudo-randomly to avoid
+ packet storms when several queries were started at the same time.
+
+Daniel Stenberg (11 Jan 2009)
+- - Phil Blundell added the internal function ares__expand_name_for_response()
+ that is now used by the ares_parse_*_reply() functions instead of the
+ ares_expand_name() simply to easier return ARES_EBADRESP for the cases where
+ the name expansion fails as in responses that really isn't expected.
+
+Gunter Knauf (30 Dec 2008)

+- Fix for Win32 targets using Watt-32.
+
+Dan Fandrich (9 Dec 2008)
+- C89 compilers (like Minix' ACK) only need to handle 31 functions arguments

+
+Gisle Vanem (8 Dec 2008)
+- Added needed defines for Watt-32 on Windows.
+
+- Undefine 'optarg', 'optind' and 'opterr' when using Watt-32
+ (to get correct linkage on Windows).

+
+- Brad Spencer provided changes to allow buildconf to work on OS X.
+
+- In preparation for the upcomming IPv6 nameservers patch, the internal
+ ares_addr union is now changed into an internal struct which also holds
+ the address family.
+
+Dan Fandrich (20 Nov 2008)
+- Make checking for struct ifreq a prerequisite for setting
+ HAVE_IOCTL_SIOCGIFADDR since it's needed to use SIOCGIFADDR and Watcom C
+ doesn't currently define it.
+
+Daniel Stenberg (20 Nov 2008)
+- use unsigned short better intead of mixing with ints to prevent compiler
+ warnings
+
+- please the picky compilers by staying with short as the data we get is short
+ only
+
+- - Brad Spencer brought the new function ares_gethostbyname_file() which simply

+
+Daniel Stenberg (1 Nov 2008)
+- Added a TODO file to list things we want changed, added or fixed.
+
+- - Carlo Contavalli added support for the glibc "rotate" option, as documented
+ in man resolv.conf:
+
+ causes round robin selection of nameservers from among those listed. This
+ has the effect of spreading the query load among all listed servers, rather
+ than having all clients try the first listed server first every time.
+
+ You can enable it with ARES_OPT_ROTATE
+
+Yang Tse (1 Nov 2008)
+- Adjust WIN32 freeaddrinfo, getaddrinfo and getnameinfo availability

+ Disable warnings on structure members padding.
+
+- With this change Solaris target builds will now be done with _REENTRANT defined.

+- Support Watt-32 under Win32.

+Yang Tse (10 Aug 2008)
+- Fix: Remove now this SIZEOF_CURL_OFF_T symbol definition.
+
+ This should have been done with the initial 64-bit curl_off_t patch.
+
+- Improve CURL_CHECK_DEF
+
+- Fix IBM C and DEC/Compaq C compiler detection
+
+- Initial support of curlbuild.h and curlrules.h which allows
+ to have a curl_off_t data type no longer gated to off_t.
+
+- The minimum autoconf version required for this file is 2.50
+
+ Avoid dot notation in aclocal serial file number, use a single number now.

+- - 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.
+
+ 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.

+- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
+ Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. But,
+ autoconf 2.62 version of AC_AIX defines _ALL_SOURCE along with other four
+ preprocessor symbols no matter if the system is AIX or not. To keep the
+ traditional behaviour, as well as an uniform one, across autoconf versions
+ AC_AIX is replaced with our own internal macro.
+
+- Adjust DEC/Compaq C compiler settings.
+
+- Another AC_TRY_LINK conversion to AC_LINK_IFELSE.
+ Proper definition of HAVE_function if function is found deeper.
+
+- Sync up with reality
+
+- Rename reentrant.m4 to avoid filename clash.
+
+- Add file version serial number that might be used by 'aclocal' and others.
+
+ Keep the '#' character as the first one on the line.
+
+- Update copyright year.
+
+- Sync comment with reality.
+
+- Reinstate the 'aclocal -I m4' in buildconf and 'ACLOCAL_AMFLAGS = -I m4' way of
+ including our local m4/reentrant.m4 file. This even takes care of including the
+ file in the distribution tarball.
+
+- Add quoting for the AC_DEFINE arguments.
+
+- Also remove the whitespace.
+
+- Also remove the extra quoting.
+
+- Replace some '@%:@' quadigraphs by its actual representation '#'.
+
+ This quadigraph used before a C preprocessor 'define' directive could
+ be fooling M4, when processing this file, and make it think that the
+ line contains a pure M4 'define' macro.
+
+- Tests done using 'aclocal -I m4' in buildconf and 'ACLOCAL_AMFLAGS = -I m4
+ in top Makefile.am triggered a problem that prevented aclocal from running
+ successfully on SunOS 5.10 with GNU m4 1.4.5 and GNU Autoconf 2.61
+
+ A tarball which reproduces mentioned problem is the one dated July-28-2008
+ http://cool.haxx.se/curl-daily/curl-7.19.0-20080728.tar.gz
+
+ We actually don't need all the bells and whistles that the above mechanism
+ provides. We only need to include our m4/reentrant.m4 file in acinclude.m4
+ so here we go with this simpler mechanism.
+
+- for debugging purposes show ACLOCAL_FLAGS
+
+- These lines were unintentionally removed in previous commit
+
+- Partially undo change that prevented SED, GREP, EGREP and AR from being changed by libtool or autoconf.
+
+- Assert that SED and GREP are set
+
+- Require autoconf 2.57 or newer
+
+- When calling aclocal, user defined ACLOCAL_FLAGS will now precede ours.
+
+- move ACLOCAL_AMFLAGS after AUTOMAKE_OPTIONS
+
+- setup.h handles definition of _REENTRANT based on NEED_REENTRANT
+ definition which might be defined in config.h or config-*.h files
+
+- Remove explicit inclusion of our m4 files first. It was interesting as a test,
+ but it breaks aclocal execution on some systems, with the following error:
+
+ Can't locate object method "rel2abs" via package "File::Spec" at /usr/local/bin/aclocal line 256.
+
+- Another step towards detecting if _REENTRANT is already defined or actually
+ needed, and being able to define it if appropriate for further configure tests
+ as well as for the generated config file.
+
+- Explicitly include our m4 files first. This might minimize the impact
+ that other package's underquoted m4 function definitions have on ours.
+
+- Add a 3 argument check for getprotobyname_r
