File c-ares-1.7.1/CHANGES

-  Changelog for the c-ares project
-
-Version 1.7.1 (Mar 23, 2010)
-
-* March 23, 2010 (Daniel Stenberg)
-- We switched from CVS to git. See http://github.com/bagder/c-ares
-
-* March 5, 2010 (Daniel Stenberg)
-- Daniel Johnson provided fixes for building with the clang compiler.
-
-* March 5, 2010 (Yang Tse)
-- Added IPv6 name servers support. Implementation has been based on code,
-  comments and feedback provided November and December of 2008 by Daniel
-  Stenberg, Gregor Jasny, Phil Blundell and myself, December 2009 by Cedric
-  Bail, and February 2010 by Jakub Hrozek on the c-ares mailing list. On
-  March I reviewed all that, selected the best of each, and adjusted or
-  extended parts of it to make the best fit.
-
-  The external and visible result of all this is that two new functions are
-  added to the external API, ares_get_servers() and ares_set_servers(), which
-  becomes now the preferred way of getting and setting name servers for any
-  ares channel as these support both IPv4 and IPv6 name servers.
-
-  In order to not break ABI compatibility, ares_init_options() with option
-  mask ARES_OPT_SERVERS and ares_save_options() may still be used in code
-  which is intended to run on IPv4-only stacks. But remember that these
-  functions do not support IPv6 name servers. This implies that if the user
-  is capable of defining or providing an IPv6 name server, and the app is
-  using ares_init_options() or ares_save_options() at some point to handle
-  the name servers, the app will likely loose IPv6 name servers.
-
-* January 28, 2010 (Daniel Stenberg)
-- 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.
-
-* December 29, 2009 (Yang Tse)
-- Laszlo Tamas Szabo adjusted Makefile.msvc compiler options so that where
-  run-time error checks enabling compiler option /GZ was used it is replaced
-  with equivalent /RTCsu for Visual Studio 2003 and newer versions. Option
-  /GX is replaced with equivalent /EHsc for all versions. Also fixed socket
-  data type for internal configure_socket function.
-
-* December 21, 2009 (Yang Tse)
-- 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.
-
-Version 1.7.0 (Nov 30, 2009)
-
-* November 26, 2009 (Yang Tse)
-- 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.
-
-* November 23, 2009 (Yang Tse)
-- Changed naming convention for c-ares libraries built with MSVC, details
-  and build instructions provided in README.msvc file.
-
-* November 22, 2009 (Yang Tse)
-- Jakub Hrozek fixed more function prototypes in man pages to sync them
-  with the ones declared in ares.h
-
-- 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 1.7.0.
-
-* November 21, 2009 (Yang Tse)
-- Added manifest stuff to Makefile.msvc.
-
-* November 20, 2009 (Yang Tse)
-- Fixed several function prototypes in man pages that were out of sync
-  with the ones declared in ares.h.  Added ares_free_data() along with
-  man page.  Updated ares_parse_srv_reply() and ares_parse_txt_reply()
-  with changes from Jakub Hrozek making these now return linked lists
-  instead of arrays, and merging the ares_free_data() adjustments.
-
-* November 10, 2009 (Yang Tse)
-- Updated MSVC 6.0 project files to match settings from Makefile.msvc.
-
-* November 9, 2009 (Yang Tse)
-- Makefile.msvc is now the reference method to build c-ares and sample
-  programs with any MSVC compiler or MS Visual Studio version.  If no
-  option or target are specified it builds dynamic and static c-ares
-  libraries in debug and release flavours and also builds all sample
-  programs using each of the different c-ares libraries.
-
-* November 2, 2009 (Yang Tse)
-- Renamed c-ares setup.h to ares_setup.h
-
-* October 31, 2009 (Yang Tse)
-- Symbol hiding configure options are named now --enable-symbol-hiding
-  and --disable-symbol-hiding in an attempt to make them less ambiguous.
-
-* October 30, 2009 (Yang Tse)
-- Many fixes for ares_parse_txt_reply()
-
-* October 29, 2009 (Daniel Stenberg)
-- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing
-
-* October 29, 2009 (Yang Tse)
-- 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.
-
-* October 28, 2009 (Yang Tse)
-- Initial step towards the ability to reduce c-ares exported symbols
-  when built as a shared library based on the 'visibility' attribute
-  for GNUC and Intel compilers and based on __global for Sun compilers,
-  taking also in account __declspec function decoration for Win32 and
-  Symbian DLL's.
-
-* October 27, 2009 (Yang Tse)
-- Fixed Pelles C Win32 target compilation issues.
-
-* October 23, 2009 (Yang Tse)
-- John Engelhart noticed an unreleased problem relative to a duplicate
-  ARES_ECANCELLED error code value and missing error code description.
-
-* October 7, 2009 (Yang Tse)
-- 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.
-
-* October 6, 2009 (Yang Tse)
-- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak.
-
-* September 29, 2009 (Yang Tse)
-- Make configure script also check if _REENTRANT definition is required to
-  make errno available as a preprocessor macro.
-
-* September 7, 2009 (Yang Tse)
-- Add T_SRV portability check to ares_parse_srv_reply.c
-
-* 4 Sep 2009 (Daniel Stenberg)
-- Jakub Hrozek added ares_parse_srv_reply() for SRV parsing
-
-* 3 Aug 2009 (Daniel Stenberg)
-- 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.
-
-- 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.
-
-* 14 Jul 2009 (Guenter Knauf)
-- renamed generated config.h to ares_config.h to avoid any future clashes
-  with config.h from other projects.
-
-* June 20 2009 (Yang Tse)
-- Refactor how libraries are checked for connect() function in configure
-  script and check for connect() as it is done for other functions.
-
-* June 19 2009 (Yang Tse)
-- Make sclose() function-like macro definition used to close a socket,
-  now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
-  config file preprocessor definitions
-
-* June 18 2009 (Yang Tse)
-- Add CloseSocket camel case function check for configure script.
-
-* June 17 2009 (Yang Tse)
-- Check for socket() and closesocket() as it is done for other functions
-  in configure script.
-
-* June 11 2009 (Yang Tse)
-- Modified buildconf so that when automake runs it copies missing files
-  instead of symlinking them.
-
-* June 8 2009 (Yang Tse)
-- Removed buildconf.bat from release and daily snapshot archives. This
-  file is only for CVS tree checkout builds.
-
-* May 26 2009 (Yang Tse)
-- Added --enable-curldebug configure option to enable and disable building
-  with the low-level curl debug memory tracking 'feature' to allow decoupled
-  setting from --enable-debug, allowing again to build c-ares independently
-  out of the CVS tree.
-
-  For the c-ares library option --enable-debug enables debug build features
-  which are _not_ related with memory tracking. For the c-ares library when
-  --enable-debug is given it does not enable the memory tracking feature. If
-  you wish to enable the curl debug memory tracking you must use configure
-  option --enable-curldebug explicitily to do so.
-
-  Internally, definition of preprocessor symbol DEBUGBUILD restricts code
-  which is only compiled for debug enabled builds. And symbol CURLDEBUG is
-  used to differentiate code which is _only_ used for memory tracking.
-
-  Make ares_init(), ares_dup() and ares_init_options() fail returning
-  ARES_ENOTINITIALIZED if library initialization has not been performed
-  calling ares_library_init().
-
-* May 20 2009 (Yang Tse)
-- Added ares_library_init() and ares_library_cleanup() man pages.
-
-* May 19 2009 (Yang Tse)
-- Introduced ares_library_init() and ares_library_cleanup() functions.
-
-  This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets
-  using c-ares 1.7.0 can still survive without calling these functions. Read all
-  the details on ares_library_init(3) and ares_library_cleanup(3) man pages that
-  are included.
-
-  curl/libcurl 7.19.5 is fully compatible with c-ares 1.7.0 on all systems.
-
-  In order to use c-ares 1.7.0 with curl/libcurl on Win32/64 systems it is
-  required that curl/libcurl is 7.19.5 or newer. In other words, it is not
-  possible on Win32/64 to use c-ares 1.7.0 with a curl/libcurl version less
-  than 7.19.5
-
-* May 11 2009 (Daniel Stenberg)
-- Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to
-  only expose functions starting with ares_.
-
-* May 7 2009 (Yang Tse)
-- Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition
-  attempt in generated config.h
-
-* May 2 2009 (Yang Tse)
-- Use a build-time configured ares_socklen_t data type instead of socklen_t.
-
-* April 21 2009 (Yang Tse)
-- Moved potential inclusion of system's malloc.h and memory.h header files to
-  setup_once.h.  Inclusion of each header file is based on the definition of
-  NEED_MALLOC_H and NEED_MEMORY_H respectively.
-
-* March 11 2009 (Yang Tse)
-- Japheth Cleaver fixed acountry.c replacing u_long with unsigned long.
-
-* February 20 2009 (Yang Tse)
-- Do not halt compilation when using VS2008 to build a Windows 2000 target.
-
-* 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.
-
-* January 31 2009 (Daniel Stenberg)
-- 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.
-
-* January 14 2009 (Daniel Stenberg)
-- 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.
-
-* January 13 2009 (Phil Blundell)
-- ares__send_query() now varies the retry timeout pseudo-randomly to avoid
-  packet storms when several queries were started at the same time.
-
-* January 11 2009 (Daniel Stenberg)
-- 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.
-
-Version 1.6.0 (Dec 9, 2008)
-
-* December 9 2008 (Gisle Vanem)
-
-  Fixes for Win32 targets using the Watt-32 tcp/ip stack.
-
-* Dec 4 2008 (Daniel Stenberg)
-
-  Gregor Jasny provided the patch that introduces ares_set_socket_callback(),
-  and I edited it to also get duped by ares_dup().
-
-* Dec 3 2008 (Daniel Stenberg)
-
-  API changes:
-
-  I made sure the public ares_config struct looks like before and yet it
-  supports the ROTATE option thanks to c-ares now storing the "optmask"
-  internally. Thus we should be ABI compatible with the past release(s)
-  now. My efforts mentioned below should not break backwards ABI compliance.
-
-  Here's how I suggest we proceed with the API:
-
-  ares_init() will be primary "channel creator" function.
-
-  ares_init_options() will continue to work exactly like now and before. For
-  starters, it will be the (only) way to set the existing options.
-
-  ares_save_options() will continue to work like today, but will ONLY save
-  options that you can set today (including ARES_OPT_ROTATE actually) but new
-  options that we add may not be saved with this.
-
-  Instead we introduce:
-
-  ares_dup() that instead can make a new channel and clone the config used
-  from an existing channel. It will then clone all config options, including
-  future new things we add.
-
-  ares_set_*() style functions that set (new) config options. As a start we
-  simply add these for new functionality, but over time we can also introduce
-  them for existing "struct ares_options" so that we can eventually deprecate
-  the two ares_*_options() functions.
-
-  ares_get_*() style functions for extracting info from a channel handle that
-  should be used instead of ares_save_options().
-
-* Nov 26 2008 (Yang Tse)
-- Brad Spencer provided changes to allow buildconf to work on OS X.
-
-- Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a
-  buffer to shrink instead of expand if a reply contained 8 or more records.
-
-* Nov 25 2008 (Yang Tse)
-- 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.
-
-* Nov 19 2008 (Daniel Stenberg)
-- Brad Spencer brought the new function ares_gethostbyname_file() which simply
-  resolves a host name from the given file, using the regular hosts syntax.
-
-* Nov 1 2008 (Daniel Stenberg)
-- 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
-
-* Oct 21 2008 (Yang Tse)
-  Charles Hardin added handling of EINPROGRESS for UDP connects.
-
-* Oct 18 2008 (Daniel Stenberg)
-  Charles Hardin made adig support a regular numerical dotted IP address for the
-  -s option as well.
-
-* Oct 7 2008 (Yang Tse)
-- Added --enable-optimize configure option to enable and disable compiler
-  optimizations to allow decoupled setting from --enable-debug.
-
-* Oct 2 2008 (Yang Tse)
-- Added --enable-warnings configure option to enable and disable strict
-  compiler warnings to allow decoupled setting from --enable-debug.
-
-* Sep 17 2008 (Yang Tse)
-- Code reorganization to allow internal/private use of "nameser.h" to any
-  system that lacks arpa/nameser.h or arpa/nameser_compat.h header files.
-
-* Sep 16 2008 (Yang Tse)
-- Code reorganization to allow internal/private use of ares_writev to any
-  system that lacks the writev function.
-
-* Sep 15 2008 (Yang Tse)
-- Code reorganization to allow internal/private use of ares_strcasecmp to any
-  system that lacks the strcasecmp function.
-
-- Improve configure detection of some string functions.
-
-* Sep 11 2008 (Yang Tse)
-- Code reorganization to allow internal/private use of ares_strdup to any
-  system that lacks the strdup function.
-
-Version 1.5.3 (Aug 29, 2008)
-
-* Aug 25 2008 (Yang Tse)
-- 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:
-  Fixed compilation of acountry sample application failure on some systems.
-
-* 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.
-
-  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.
-
-
-* Aug 4 2008 (Yang Tse)
-- 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. 2.62
-  version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols
-  no matter if the system is AIX or not. To keep the traditional behaviour,
-  and an uniform one across autoconf versions AC_AIX is replaced with our
-  own internal macro CARES_CHECK_AIX_ALL_SOURCE.
-
-* Aug 1 2008 (Yang Tse)
-- Configure process now checks if the preprocessor _REENTRANT symbol is already
-  defined. If it isn't currently defined a set of checks are performed to test
-  if its definition is required to make visible to the compiler a set of *_r
-  functions. Finally, if _REENTRANT is already defined or needed it takes care
-  of making adjustments necessary to ensure that it is defined equally for the
-  configure process tests and generated config file.
-
-* Jul 20 2008 (Yang Tse)
-- When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
-  now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID,
-  RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID.
-
-* Jul 17 2008 (Yang Tse)
-- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined
-  to the data type pointed by its respective argument and not the pointer type.
-
-* Jul 16 2008 (Yang Tse)
-- Improved configure detection of number of arguments for getservbyport_r.
-  Detection is now based on compilation checks instead of linker ones.
-
-- Configure process now checks availability of recvfrom() socket function and
-  finds out its return type and the types of its arguments. Added definitions
-  for non-configure systems config files, and introduced macro sreadfrom which
-  will be used on udp sockets as a recvfrom() wrapper in the future.
-
-* Jul 15 2008 (Yang Tse)
-- Introduce definition of _REENTRANT symbol in setup.h to improve library
-  usability.  Previously the configure process only used the AC_SYS_LARGEFILE
-  macro for debug builds, now it is also used for non-debug ones enabling the
-  use of configure options --enable-largefile and --disable-largefile which
-  might be needed for library compatibility.  Remove checking the size of
-  curl_off_t, it is no longer needed.
-
-* Jul 3 2008 (Daniel Stenberg)
-- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and
-  the target host has only A records, it automatically falls back to an
-  AF_INET lookup and gives you the A results.  However, if the target host has
-  a CNAME record, this behaviour is defeated since the original query does
-  return some data even though ares_parse_aaa_reply() doesn't consider it
-  relevant. Here's a small patch to make it behave the same with and without
-  the CNAME.
-
-* Jul 2 2008 (Yang Tse)
-- Fallback to gettimeofday when monotonic clock is unavailable at run-time.
-
-* Jun 30 2008 (Daniel Stenberg)
-
-- As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is
-  not posix or anything and thus c-ares failed to build on hurd (and possibly
-  elsewhere). The define was also somewhat artificially used in the windows
-  port. Now, I instead rewrote the use of gethostbyname to enlarge the host
-  name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN
-  define. I thus also removed the defien from the namser.h file where it was
-  once added for the windows build.
-
-  I also fixed init_by_defaults() function to not leak memory in case if
-  error.
-
-* Jun 9 2008 (Yang Tse)
-
-- Make libcares.pc generated file for pkg-config include information relative
-  to the libraries needed for the static linking of c-ares.
-
-* May 30 2008 (Yang Tse)
-
-- Brad House fixed a missing header file inclusion in adig sample program.
-
-Version 1.5.2 (May 29, 2008)
-
-* May 13 2008 (Daniel Stenberg)
-
-- Introducing millisecond resolution support for the timeout option. See
-  ares_init_options()'s ARES_OPT_TIMEOUTMS.
-
-* May 9 2008 (Yang Tse)
-
-- Use monotonic time source if available, for private function ares__tvnow()
-
-* May 7 2008 (Daniel Stenberg)
-
-- Sebastian made c-ares able to return all PTR-records when doing reverse
-  lookups. It is not common practice to have multiple PTR-Records for a single
-  IP, but its perfectly legal and some sites have those.
-
-- Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to
-  autoconf 2.57 usage (which is the version you have specified as the minimum
-  version). It's a minor change but it does clean up some warnings with newer
-  autoconf (specifically 2.62).
-
-* May 5 2008 (Yang Tse)
-
-- Improved parsing of resolver configuration files.
-
-* April 4 2008 (Daniel Stenberg)
-
-- Eino Tuominen improved the code when a file is used to seed the randomizer.
-
-- Alexey Simak made adig support NAPTR records
-
-- Alexey Simak fixed the VC dsp file by adding the missing source file
-  ares_expand_string.c
-
-* December 11 2007 (Gisle Vanem)
-
-- Added another sample application; acountry.c which converts an
-  IPv4-address(es) and/or host-name(s) to country-name and country-code.
-  This uses the service of the DNSBL at countries.nerd.dk.
-
-* December 3 2007 (Daniel Stenberg)
-
-- Brad Spencer fixed the configure script to assume that there's no
-  /dev/urandom when built cross-compiled as then the script cannot check for
-  it.
-
-- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat
-
-Version 1.5.1 (Nov 21, 2007)
-
-* November 21 2007 (Daniel Stenberg)
-
-- Robin Cornelius pointed out that ares_llist.h was missing in the release
-  archive for 1.5.0
-
-Version 1.5.0 (Nov 21, 2007)
-
-* October 2 2007 (Daniel Stenberg)
-
-- ares_strerror() segfaulted if the input error number was out of the currently
-  supported range.
-
-- Yang Tse: Avoid a segfault when generating a DNS "Transaction ID" in
-  internal function init_id_key() under low memory conditions.
-
-* September 28 2007 (Daniel Stenberg)
-
-- Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI
-  and API changes in the progress callback (and possibly more coming up from
-  Steinar)
-
-* September 28 2007 (Steinar H. Gunderson)
-
-- Don't skip a server if it's the only one. (Bugfix from the Google tree.)
-
-- Made the query callbacks receive the number of timeouts that happened during
-  the execution of a query, and updated documentation accordingly. (Patch from
-  the Google tree.)
-
-- Support a few more socket options: ARES_OPT_SOCK_SNDBUF and
-  ARES_OPT_SOCK_RCVBUF
-
-- Always register for TCP events even if there are no outstanding queries, as
-  the other side could always close the connection, which is a valid event
-  which should be responded to.
-
-* September 22 2007 (Daniel Stenberg)
-
-- Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in
-  several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that
-  if it fails and the socket is closed the following code doesn't try to use
-  the file descriptor.
-
-- Steinar H. Gunderson modified c-ares to now also do to DNS retries even when
-  TCP is used since there are several edge cases where it still makes sense.
-
-- Brad House provided a fix for ares_save_options():
-
-  Apparently I overlooked something with the ares_save_options() where it
-  would try to do a malloc(0) when no options of that type needed to be saved.
-  On most platforms, this was fine because malloc(0) doesn't actually return
-  NULL, but on AIX it does, so ares_save_options would return ARES_ENOMEM.
-
-* July 14 2007 (Daniel Stenberg)
-
-- Vlad Dinulescu fixed two outstanding valgrind reports:
-
-  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,
-  DNS_HEADER_SET_QID is used to set the value of qid, but DNS_HEADER_SET_QID
-  sets only the first two bytes of qid. I think that qid should be declared as
-  "unsigned short" in this function.
-
-  2. The same problem occurs in ares_process.c, process_answer() .  query->qid
-  (an unsigned short integer variable) is compared with id, which is an
-  integer variable. Moreover, id is initialized from DNS_HEADER_QID which sets
-  only the first two bytes of id. I think that the id variable should be
-  declared as "unsigned short" in this function.
-
-  Even after declaring these variables as "unsigned short", the valgrind
-  errors are still there. Which brings us to the third problem.
-
-  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.
-  I have studied ares__rc4() too, and this is the offending line:
-
-        buffer_ptr[counter] ^= state[xorIndex];   (ares_query.c:62)
-
-  This is what triggers Valgrind.. buffer_ptr is unitialised in this function,
-  and by applying ^= on it, it remains unitialised.
-
-Version 1.4.0 (June 8, 2007)
-
-* June 4 2007 (Daniel Stenberg)
-
-- James Bursa reported a major memory problem when resolving multi-IP names
-  and I found and fixed the problem. It was added by Ashish Sharma's patch
-  two days ago.
-
-  When I then tried to verify multiple entries in /etc/hosts after my fix, I
-  got another segfault and decided this code was not ripe for inclusion and I
-  reverted the patch.
-
-* June 2 2007
-
-- Brad Spencer found and fixed three flaws in the code, found with the new
-  gcc 4.2.0 warning: -Waddress
-
-- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
-  He also made recent Microsoft compilers use _strdup() instead of strdup().
-
-- Brad House's man pages for ares_save_options() and ares_destroy_options()
-  were added.
-
-- Ashish Sharma provided a patch for supporting multiple entries in the
-  /etc/hosts file. Patch edited for coding style and functionality by me
-  (Daniel).
-
-* May 30 2007
-
-- Shmulik Regev brought cryptographically secure transaction IDs:
-
-  The c-ares library implementation uses a DNS "Transaction ID" field that is
-  seeded with a pseudo random number (based on gettimeofday) which 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.
-
-  The patch I wrote changes the implementation to use a more secure way of
-  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.
-
-  Note that the key generation code (in ares_init:randomize_key) has two
-  versions, the Windows specific one uses a cryptographically safe function
-  provided (but undocumented :) by the operating system (described at
-  http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx).  The
-  default implementation is a bit naive and uses the standard 'rand'
-  function. Surely a better way to generate random keys exists for other
-  platforms.
-
-  The patch can be tested by using the adig utility and using the '-s' option.
-
-- Brad House added ares_save_options() and ares_destroy_options() that can be
-  used to keep options for later re-usal when ares_init_options() is used.
-
-  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.
-
-  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.
-
-- Daniel S added ares_process_fd() to allow applications to ask for processing
-  on specific sockets and thus avoiding select() and associated
-  functions/macros.  This function will be used by upcoming libcurl releases
-  for this very reason. It also made me export the ares_socket_t type in the
-  public ares.h header file, since ares_process_fd() uses that type for two of
-  the arguments.
-
-* May 25 2007
-
-- Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows
-  that could cause it to return a bad return code.
-
-* April 16 2007
-
-- Yang Tse: Provide ares_getopt() command-line parser function as a source
-  code helper function, not belonging to the actual c-ares library.
-
-* February 19 2007
-
-- Vlad Dinulescu added ares_parse_ns_reply().
-
-* February 13 2007
-
-- Yang Tse: Fix failure to get the search sequence of /etc/hosts and
-  DNS from /etc/nsswitch.conf, /etc/host.conf or /etc/svc.conf when
-  /etc/resolv.conf did not exist or was unable to read it.
-
-* November 22 2006
-
-- Install ares_dns.h too
-
-- Michael Wallner fixed this problem: When I set domains in the options
-  struct, and there are domain/search entries in /etc/resolv.conf, the domains
-  of the options struct will be overridden.
-
-* November 6 2006
-
-- Yang Tse removed a couple of potential zero size memory allocations.
-
-- Andreas Rieke fixed the line endings in the areslib.dsp file that I (Daniel)
-  broke in the 1.3.2 release. We should switch to a system where that file is
-  auto-generated. We could rip some code for that from curl...
-
-Version 1.3.2 (November 3, 2006)
-
-* October 12 2006
-
-- Prevent ares_getsock() to overflow if more than 16 sockets are used.
-
-* September 11 2006
-
-- Guilherme Balena Versiani: I noted a strange BUG in Win32 port
-  (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network
-  by hand or disconnect the network cable in Windows 2000 or Windows XP, my
-  application gets 127.0.0.1 as the only name server. The problem comes from
-  'GetNetworkParams' function, that returns the empty string "" as the only
-  name server in that case. Moreover, the Windows implementation of
-  inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE.
-
-* August 29 2006
-
-- Brad Spencer did
-
-  o made ares_version.h use extern "C" for c++ compilers
-  o fixed compiler warnings in ares_getnameinfo.c
-  o fixed a buffer position init for TCP reads
-
-* August 3 2006
-
-- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
-  not always zero!
-
-Version 1.3.1 (June 24, 2006)
-
-* July 23, 2006
-
-- Gisle Vanem added getopt() to the ahost program. Currently accepts
-  only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
-
-* June 19, 2006
-
-- (wahern) Removed "big endian" DNS section and RR data integer parser
-  macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise
-  operations in C operate on logical values. And in any event the octets are
-  already in big-endian (aka network) byte order so they're being reversed
-  (thus the source of the breakage).
-
-* June 18, 2006
-
-- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
-  from area_process.c.
-
-  TODO: Handle one last EAGAIN for a UDP socket send(2) in
-  ares__send_query().
-
-* May 10, 2006
-
-- Bram Matthys brought my attention to a libtool peculiarity where detecting
-  things such as C++ compiler actually is a bad thing and since we don't need
-  that detection I added a work-around, much inspired by a previous patch by
-  Paolo Bonzini. This also shortens the configure script quite a lot.
-
-* May 3, 2006
-
-- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes
-  c-ares call a callback on socket state changes. A better way than the
-  ares_getsock() to get full control over the socket state.
-
-* January 9, 2006
-
-- Alexander Lazic improved the getservbyport_r() configure check.
-
-* January 6, 2006
-
-- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
-  variable for easier controlling what it does and how it runs.
-
-* January 5, 2006
-
-- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it
-  build with newer gcc versions that no longer defines "riscos".
-
-* December 22
-
-- Daniel Stenberg added ares_getsock() that extracts the set of sockets to
-  wait for action on. Similar to ares_fds() but not restricted to using
-  select() for the waiting.
-
-* November 25
-
-- Yang Tse fixed some send() / recv() compiler warnings
-
-* September 18
-
-- Added constants that will be used by ares_getaddrinfo
-
-- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it
-  is available to ensure it works properly in a threaded environment.
-
-* September 10
-
-- configure fix for detecting a member in the sockaddr_in6 struct which failed
-  on ipv6-enabled HP-UX 11.00
-
-Version 1.3.0 (August 29, 2005)
-
-* August 21
-
-- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info()
-  when getting the DNS server etc.
-
-* June 19
-
-- Added some checks for the addrinfo structure.
-
-* June 2
-
-- William Ahern:
-
-  Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a
-  read event can come back from poll() on a valid SOCK_DGRAM socket but
-  recv(2) will still block. This patch doesn't ignore EAGAIN in
-  read_udp_packets(), though maybe it should. (This patch was edited by Daniel
-  Stenberg and a new configure test was added (imported from curl's configure)
-  to properly detect what non-blocking socket approach to use.)
-
-  I'm not quite sure how this was happening, but I've been seeing PTR queries
-  which seem to return empty responses. At least, they were empty when calling
-  ares_expand_name() on the record. Here's a patch which guarantees to
-  NUL-terminate the expanded name. The old behavior failed to NUL-terminate if
-  len was 0, and this was causing strlen() to run past the end of the buffer
-  after calling ares_expand_name() and getting ARES_SUCCESS as the return
-  value. If q is not greater than *s then it's equal and *s is always
-  allocated with at least one byte.
-
-* May 16
-
-- Added ares_getnameinfo which mimics the getnameinfo API (another feature
-  that could use testing).
-
-* May 14
-
-- Added an inet_ntop function from BIND for systems that do not have it.
-
-* April 9
-
-- Made sortlist support IPv6 (this can probably use some testing).
-
-- Made sortlist support CIDR matching for IPv4.
-
-* April 8
-
-- 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.
-
-- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
-  The function can lookup IPv6 addresses both from files (/etc/hosts) and
-  DNS lookups.
-
-* April 7
-
-- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
-  OS X.
-
-* April 5
-
-- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
-  from BIND for systems that do not include these functions.
-
-* March 11, 2005
-
-- Dominick Meglio added ares_parse_aaaa_reply.c and did various
-  adjustments. The first little steps towards IPv6 support!
-
-* November 7
-
-- Fixed the VC project and makefile to use ares_cancel and ares_version
-
-* October 24
-
-- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw.
-  This is now fixed.
-
-Version 1.2.1 (October 20, 2004)
-
-* September 29
-
-- 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.
-
-- Now c-ares will use local host name lookup _before_ DNS resolving by default
-  if nothing else is told.
-
-* September 26
-
-- 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.
-
-  c-ares now looks at
-
-  1) resolv.conf (for the "lookup" line);
-  2) nsswitch.fon (for the "hosts:" line);
-  3) host.conf (for the "order" line).
-
-  First match wins.
-
-- 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.
-
-  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
-
-  The patch will make c-ares correctly consult the registry for the location
-  of this file.
-
-* August 29
-
-- Gisle Vanem fixed the MSVC build files.
-
-* August 20
-
-- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
-
-* August 13
-
-- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
-  fine with MSVC 7.1
-
-* July 24
-
-- Made the lib get built static only if --enable-debug is used.
-
-- Gisle Vanem fixed:
-
-  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.
-
-  The next problem was that 'server->tcp_buffer_pos' had a random value at
-  entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
-
-  I've also added a ares_writev() for Windows to streamline the code a bit
-  more.
-
-* 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.
-
-- Made configure create config.h, and all source files now include setup.h that
-  might include the proper config.h (or a handicrafted alternative).
-
-- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
-  use 'int' for that.
-
-- 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!)
-
-- 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.
-
-- Adjusted 'maketgz' to use the new automake magic when building distribution
-  archives.
-
-- Anyone desires HTML and/or PDF versions of the man pages in the release
-  archives?
-
-* July 3
-- G�nter Knauf made c-ares build and run on Novell Netware.
-
-* 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.
-
-* June 30
-- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.
-
-* June 10
-- Gisle Vanem's init patch for Windows:
-
-  The init_by_resolv_conf() function fetches the DNS-server(s)
-  from a series of registry branches.
-
-  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.
-
-  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).
-
-  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.
-
-* June 8
-- James Bursa fixed an init issue for RISC OS.
-
-* 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.
-
-  This is now adjusted in the code
-
-Version 1.2.0 (April 13, 2004)
-
-* April 2, 2004
-- Updated various man pages to look nicer when converted to HTML on the web
-  site.
-
-* 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.
-
-- Dominick Meglio cleaned up the formatting in several man pages.
-
-* March 30, 2004
-- Dominick Meglio's new ares_expand_string. A helper function when decoding
-  incoming DNS packages.
-
-- Daniel Stenberg modified the Makefile.in to use a for loop for the man page
-  installation to improve overview and make it easier to add man pages.
-
-Version 1.1.0 (March 11, 2004)
-
-* March 9, 2004
-- Gisle Vanem improved build on Windows.
-
-* February 25, 2004
-- Dan Fandrich found a flaw in the Feb 22 fix.
-
-- Added better configure --enable-debug logic (taken from the curl configure
-  script). Added acinclude.m4 to the tarball.
-
-* February 23, 2004
-- Removed ares_free_errmem(), the function, the file and the man page. It was
-  not used and it did nothing.
-
-- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
-  compiler warnings on picky compilers.
-
-* February 22, 2004
-- Dominick Meglio made ares init support multiple name servers in the
-  NameServer key on Windows.
-
-* February 16, 2004
-- Modified ares_private.h to include libcurl's memory debug header if
-  CURLDEBUG is set. This makes all the ares-functions supervised properly by
-  the curl test suite. This also forced me to add inclusion of the
-  ares_private.h header in a few more files that are using some kind of
-  memory-related resources.
-
-- Made the makefile only build ahost and adig if 'make demos' is used.
-
-* February 10, 2004
-- Dirk Manske made ares_version.h installed with 'make install'
-
-* February 4, 2004
-- ares_free_errmem() is subject for removal, it is simply present for future
-  purposes, and since we removed the extra parameter in strerror() it won't
-  be used by c-ares!
-- configure --enable-debug now enables picky compiler options if gcc is used
-- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk
-  reported
-
-Version 1.0.0 (February 3, 2004)
-
-* February 3, 2004
-- now we produce the libcares.a library instead of the previous libares.a
-  since we are no longer compatible
-
-* February 2, 2004
-
-- ares_strerror() has one argument less. This is the first official
-  modification of the existing provided ares API.
-
-* January 29, 2004
-
-- Dirk Manske fixed how the socket is set non-blocking.
-
-* January 4, 2004
-
-- Dominick Meglio made the private gettimeofday() become ares_gettimeofday()
-  instead in order to not pollute the name space and risk colliding with
-  other libraries' versions of this function.
-
-* October 24, 2003. Daniel Stenberg
-
-  Added ares_version().
-
-Version 1.0-pre1 (8 October 2003)
-
-- James Bursa made it run on RISC OS
-
-- Dominick Meglio made it run fine on NT4
-
-- Duncan Wilcox made it work fine on Mac OS X
-
-- Daniel Stenberg adjusted the windows port
-
-- liren at vivisimo.com made the initial windows port
-
-* Imported the sources from ares 1.1.1

-# 1.
-#
-# If either revision or age are omitted, they default to 0. Also note that age

-# Here are a set of rules to help you update your library version information: 
-#
-# 1.Start with version information of 0:0:0 for each libtool library.
-#
-# 2.Update the version information only immediately before a public release of
-# your software. More frequent updates are unnecessary, and only guarantee
-# that the current interface number gets larger faster.
-#
-# 3.If the library source code has changed at all since the last update, then
-# increment revision (c:r+1:a)
-#
-# 4.If any interfaces have been added, removed, or changed since the last
-# update, increment current, and set revision to 0. (c+1:r=0:a)
-#
-# 5.If any interfaces have been added since the last public release, then
-# increment age. (c:r:a+1)
