-
-Version 1.7.1 (Mar 23, 2010)
-
-* May 31, 2010 (Jakub Hrozek)
-- Use the last instance of domain/search, not the first one
-
-* 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 lose 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.
+- ares_version.h: copyright end range year is now 2013
 
-* November 23, 2009 (Yang Tse)
-- Changed naming convention for c-ares libraries built with MSVC, details
-  and build instructions provided in README.msvc file.
+- RELEASE-NOTES: synced with fb0737f3a0a1c37
 
-* November 22, 2009 (Yang Tse)
-- Jakub Hrozek fixed more function prototypes in man pages to sync them
-  with the ones declared in ares.h
+- [Paul Saab brought this change]
+
+  ares_parse_aaaa_reply: Plug memory leak
+  
+  This change is similar to ares_parse_a_reply.c in commit
+  bffd67f16a8f42fe6dbf79ab2e39d92eea05c8a6
+
+- [Patrick Valsecchi brought this change]
 
-- 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.
+  ares_parse_txt_reply: return a ares_txt_reply node for each sub-string
+  
+  Previously, the function would wrongly return all substrings merged into
+  one.
 
-* 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.
+- [Alexander Klauer brought this change]
 
-* November 10, 2009 (Yang Tse)
-- Updated MSVC 6.0 project files to match settings from Makefile.msvc.
+  library init: documentation update
+  
+  This commit updates the documentation of ares_library_init() and
+  ares_library_cleanup() with regard to the newly introduced reference
+  counting of initializations and deinitializations.
 
-* 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
+- [Alexander Klauer brought this change]
 
-* 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.
+  library init: be recursive
+  
+  Previously, a single call to ares_library_cleanup() would deinitialise
+  the c-ares library, regardless of how many times ares_library_init() was
+  called. This behaviour may cause problems in programs linking two or
+  more libraries which, in turn, use c-ares. The present commit fixes this
+  problem, deinitializing the library only after a number of calls to
+  ares_library_cleanup() matching the number of calls to
+  ares_library_init().
 
-* October 30, 2009 (Yang Tse)
-- Many fixes for ares_parse_txt_reply()
+- [Patrick Valsecchi brought this change]
 
-* October 29, 2009 (Daniel Stenberg)
-- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing
+  protocol parsing: check input data stricter
+  
+  ... so that bad length fields aren't blindly accepted
+  
+  Bug: http://c-ares.haxx.se/mail/c-ares-archive-2013-04/0016.shtml
+
+Guenter Knauf (11 Apr 2013)
+- Create ares_build.h when buidling from Git.
+
+- Added -DCARES_STATICLIB to CFLAGS.
+  
+  Currently this static makefile does only support building the
+  static library libcares.a.
+
+Daniel Stenberg (8 Apr 2013)
+- [Alexander Klauer brought this change]
+
+  .gitignore: ignore patch files
+  
+  This commit adds a line to .gitignore to the effect that patch files
+  generated by 'git format-patch' are excluded from the repository.
+
+- [Alexander Klauer brought this change]
+
+  ares_destroy() documentation: no new requests
+  
+  Clarify that no new requests may be added to a resolver channel that is
+  currently being destroyed.
+
+- [Alexander Klauer brought this change]
+
+  Documentation: properly document ARES_ECANCELLED
+  
+  This commit clarifies the behaviour of ares_cancel() with respect to
+  callbacks and adds missing documentation of ARES_ECANCELLED to the man
+  pages of the affected functions.
+
+- [Alexander Klauer brought this change]
+
+  ares_cancel(): cancel requests safely
+  
+  An invocation of ares_cancel() walks through the request list, calling
+  the callbacks of all pending requests on a channel. Previously, if such
+  a callback added a new request to the channel, the request list might
+  not end up empty, causing an abort by assertion failure. The present
+  commit ensures that precisely all requests present upon entry of
+  ares_cancel() are cancelled, and that adding new requests through
+  callbacks is safe.
+
+Yang Tse (10 Mar 2013)
+- ares.h: stricter CARES_EXTERN linkage decorations logic
+  
+  No API change involved.
+
+- ares_build.h.dist: enhance non-configure GCC ABI detection logic
+  
+  GCC specific adjustments:
+  
+  - check __ILP32__ before 32 and 64bit processor architectures in
+    order to detect ILP32 programming model on 64 bit processors
+    which, of course, also support LP64 programming model, when using
+    gcc 4.7 or newer.
+  
+  - keep 32bit processor architecture checks in order to support gcc
+    versions older than 4.7 which don't define __ILP32__
+  
+  - check __LP64__ for gcc 3.3 and newer, while keeping 64bit processor
+    architecture checks for older versions which don't define __LP64__
+
+Daniel Stenberg (9 Mar 2013)
+- ares.h: there is no ares_free_soa function
+
+Yang Tse (9 Mar 2013)
+- Makefile.am: empty AM_LDFLAGS definition for automake 1.7 compatibility
+
+- ares_inet_ntop.3: s/socklen_t/ares_socklen_t
+
+- configure: use XC_LIBTOOL for portability across libtool versions
+
+- xc-lt-iface.m4: provide XC_LIBTOOL macro
+
+- Makefile.am: use AM_CPPFLAGS instead of INCLUDES
+
+- inet_ntop.c: s/socklen_t/ares_socklen_t
+
+- inet_ntop.c: s/socklen_t/ares_socklen_t for portability
+
+Daniel Stenberg (19 Feb 2013)
+- ares.h: s/socklen_t/ares_socklen_t for portability
+
+- ares_inet_ntop.3: 4th argument is socklen_t!
+
+- spell inet correctly!
+
+- ares_inet_pton/ntop: cleanup
+  
+  Make sure that the symbols are always exported and present in c-ares.
+  
+  Make the headers prefixed with 'ares'.
+  
+  Removed the inet_ntop.h version as it no longer features any content.
+
+- ares_inet_ntop/ares_inet_pton: added man pages
+
+Yang Tse (15 Feb 2013)
+- [Gisle Vanem brought this change]
+
+  curl_setup_once.h: definition of HAVE_CLOSE_S defines sclose() to close_s()
+
+- [Gisle Vanem brought this change]
+
+  config-dos.h: define HAVE_CLOSE_S for MSDOS/Watt-32
+
+- [Gisle Vanem brought this change]
+
+  config-dos.h: define strerror() to strerror_s_() for High-C
+
+Daniel Stenberg (13 Feb 2013)
+- ares_get_datatype: removed unused function
+  
+  it was also wrongly named as internal functions require two underscores
+
+- ares__bitncmp: use two underscores for private functions
+  
+  It used a single one previously making it look like a public one
+
+- ares__generate_new_id: moved to ares_query.c
+  
+  ... and ares__rc4 is turned into a local static function.
+
+- ares__swap_lists: make private and static
+  
+  ... since there's only one user, make it static within ares_process.c
+
+Yang Tse (13 Feb 2013)
+- Makefile.msvc: add four VS version strings
+
+Daniel Stenberg (13 Feb 2013)
+- ares_expand_name.3: clarify how to free the data
+
+Yang Tse (30 Jan 2013)
+- zz40-xc-ovr.m4: fix 'wc' detection - follow-up 2
+  
+  - Fix a pair of single quotes to double quotes.
+  
+  URL: http://curl.haxx.se/mail/lib-2013-01/0355.html
+  Reported by: Tor Arntsen
+
+- zz40-xc-ovr.m4: fix 'wc' detection - follow-up
+  
+  - Take into account that 'wc' may return leading spaces and/or tabs.
+  
+  - Set initial IFS to space, tab and newline.
+
+- zz40-xc-ovr.m4: fix 'wc' detection
+  
+  - Take into account that 'wc' may return leading spaces.
+  
+  - Set internationalization behavior variables.
+  
+  Tor Arntsen analyzed and reported the issue.
+  
+  URL: http://curl.haxx.se/mail/lib-2013-01/0351.html
+
+- zz40-xc-ovr.m4: check another three basic utilities
+
+- zz40-xc-ovr.m4: 1.0 interface stabilization
+  
+  - Stabilization results in 4 public interface m4 macros:
+    XC_CONFIGURE_PREAMBLE
+    XC_CONFIGURE_PREAMBLE_VER_MAJOR
+    XC_CONFIGURE_PREAMBLE_VER_MINOR
+    XC_CHECK_PATH_SEPARATOR
+  - Avoid one level of internal indirection
+  - Update comments
+  - Drop XC_OVR_ZZ40 macro
+
+- zz40-xc-ovr.m4: emit witness message in configure BODY
+  
+  This avoids witness message in output when running configure --help,
+  while sending the message to config.log for other configure runs.
+
+- zz40-xc-ovr.m4: truly do version conditional overriding
+  
+  - version conditional overriding
+  - catch unexpanded XC macros
+  - fix double words in comments
+
+- zz40-xc-ovr.m4: fix variable assignment of subshell output bashism
+  
+  Tor Arntsen analyzed and reported the issue.
+  
+  URL: http://curl.haxx.se/mail/lib-2013-01/0306.html
+
+- zz40-xc-ovr.m4: reinstate strict AC_REQUIRE macro dependencies
+
+- zz40-xc-ovr.m4: avoid double single-quote usage
+
+- zz40-xc-ovr.m4: parentheses balancing of 'case' statements
+  
+  m4 quadrigraph shell comment technique allows proper autoconf
+  parentheses balancing in shell 'case' statements. The presence
+  of unbalanced parentheses may otherwise trigger expansion bugs.
+
+- zz40-xc-ovr.m4: internals overhauling
+  
+  - Update comments
+  - Execute commands in subshells
+  - Faster path separator check
+  - Fix missing 'test' command
+  - Rename private macros
+  - Minimize AC_REQUIRE usage
+
+- zz40-xc-ovr.m4: redirect errors and warnings to stderr
+
+- configure: use XC_CONFIGURE_PREAMBLE early checks
+  
+  Some basic checks we make were placed early enough in generated
+  configure script when using autoconf 2.5X versions. Newer autoconf
+  versions expand these checks much further into the configure script,
+  rendering them useless. Using XC_CONFIGURE_PREAMBLE fixes placement
+  of early intended checks across all our autoconf supported versions.
+
+- zz40-xc-ovr.m4: provide XC_CONFIGURE_PREAMBLE macro
+
+- configure: autotools compatibility fixes - step I
+  
+  Fix proper macro expansion order across autotools versions for
+  C compiler and preprocessor program checks.
+
+- configure: fix automake 1.13 compatibility
+  
+  Tested with:
+  
+  buildconf: autoconf version 2.69
+  buildconf: autom4te version 2.69
+  buildconf: autoheader version 2.69
+  buildconf: automake version 1.13.1
+  buildconf: aclocal version 1.13.1
+  buildconf: libtool version 2.4
+  buildconf: GNU m4 version 1.4.16
+
+- ares_private.h: use again memdebug.h instead of curl_memdebug.h
+
+- configure.ac: replace AM_CONFIG_HEADER with AC_CONFIG_HEADERS
+  
+  automake 1.13 errors if AM_CONFIG_HEADER is used in configure script.
+
+- cares-override.m4: provide AC_CONFIG_MACRO_DIR definition conditionally
+  
+  Provide a 'traceable' AC_CONFIG_MACRO_DIR definition only when using
+  an autoconf version that does not provide it, instead of what we were
+  doing up to now of providing and overriding AC_CONFIG_MACRO_DIR for
+  all autoconf versions.
+
+- ares_private.h: use curl_memdebug.h instead of memdebug.h
+
+- vc6cares.dsp: add ares_create_query.c and ares_parse_soa_reply.c
+
+- cares-functions.m4: improve gethostname arg 2 data type check
+
+- setup_once.h: HP-UX specific 'bool', 'false' and 'true' definitions.
+  
+  Also reverts commit bceb40095a
+
+- configure: check if compiler halts on function prototype mismatch
+
+- cares-functions.m4: add gethostname arg 2 data type check and definition
+
+- cares-functions.m4: update thread-safeness detection of getaddrinfo()
+  
+  Take in account that POSIX standard Issue 7 drops h_errno support. Now, we also
+  consider getaddrinfo() to be thread-safe when (_POSIX_C_SOURCE >= 200809L) or
+  (_XOPEN_SOURCE >= 700) independently of whether h_errno exists or not.
+  
+  Take in account that h_errno might be a modifiable lvalue not defined as
+  a C preprocessor macro.
+
+- setup_once.h: HP-UX <sys/socket.h> issue workaround
+  
+  Issue: When building a 32bit target with large file support HP-UX
+  <sys/socket.h> header file may simultaneously provide two different
+  sets of declarations for sendfile and sendpath functions, one with
+  static and another with external linkage. Given that we do not use
+  mentioned functions we really don't care which linkage is the
+  appropriate one, but on the other hand, the double declaration emmits
+  warnings when using the HP-UX compiler and errors when using modern
+  gcc versions resulting in fatal compilation errors.
+  
+  Mentioned issue is now fixed as long as we don't use sendfile nor
+  sendpath functions.
+
+- setup_once.h: refactor inclusion of <unistd.h> and <sys/socket.h>
+  
+  Inclusion of these two header files now done in setup_once.h
+
+- Header inclusion clean-up
+  
+  Remove header inclusions already done in setup_once.h
+
+- setup_once.h: HP-UX specific TRUE and FALSE definitions
+  
+  Some HP-UX system headers require TRUE defined to 1 and FALSE to 0.
+
+- ares_timeout.c: fix compiler warning
+
+- ares_create_query.c: IRIX compilation fix
+
+- c-ares/nameser.h: add some T_* defines for ns_t_* values
+
+Daniel Stenberg (7 Nov 2012)
+- Revert "ares_parse_aaaa_reply: fix memory leak"
+  
+  This reverts commit 50f25d8a4b2d16f4c5e0ef620238688b7a315c7a.

+
+  read_udp_packets: bail out loop on bad sockets
+  
+  I can see that recvfrom() in ares_process.c many times is called with
+  'udp_socket' == ARES_SOCKET_BAD. The code takes care not to call
+  recv/recvfrom with ARES_SOCKET_BAD in the outer-loop. So should the
+  inner-loop.

+- cares-compilers.m4: remove -Wstrict-aliasing=3 from clang
+  
+  Currently it is unknown if there is any version of clang that

+  are several that don't support it.
+
+- cares-compilers.m4: -Wstrict-aliasing=3 for warning enabled gcc and clang builds

+  Fix UDP and TCP port byte order in saved options.
+  
+  The UDP and TCP port are stored in network byte order in the
+  ares_channeldata, but are passed in to ares_init_options() in host byte
+  order.  Thus we must return them from ares_save_options() in host byte
+  order too, or a duplicated channel will convert them again, leading to a
+  nonfunctional channel and a mysterious connection refused error from
+  ares_gethostbyname().  This breaks ares_dup(), thus the curl easy API
+  when c-ares is used by curl, and thus all the curl easy API's users.

+- - Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't

+- When using icc, compile with -fpic and link with intel dynamic libraries.
+
+- Added 'currently' in italics to insist on transient situation.
+
+- Fix language
+
+- Daniel wants upcoming release to be 1.7.0
+
+- Mention last changes
+
+- - Removed from external interface preprocessor symbol definition for
+    CARES_HAVE_ARES_FREE_DATA. Current functionality of ares_free_data()
+    makes it unnecessary.
+
+- Added README.msvc
+
+- Changed c-ares naming conventions when using MSVC as described in README.msvc
+
+- - Mention other recent changes
+
+- - Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and
+    ares_addr6ttl in order to prevent name space pollution, along with
+    necessary changes to code base and man pages.This change does not break
+    ABI, there is no need to recompile existing applications. But existing
+    applications using these structs with the old name will need source code
+    adjustments when recompiled using c-ares 1.6.1.
+
+- - Jakub Hrozek fixed more function prototypes in man pages to sync them
+    with the ones declared in ares.h
+
+- Make configure remove the ares_build.h file included in distribution tarballs.
+
+- Fix macro redefinition.
+
+- Fix name space pollution.
+
+- Allow using different extra import libraries for debug and release builds.
+
+- Add manifest stuff to msvc makefile
+
+- Sync man page with reality
+
+- Add missing external API decoration for ares_set_socket_callback()
+
+- Add ares_free_data() man page.
+
+- - Provide in external interface preprocessor symbol definitions for
+    CARES_HAVE_ARES_FREE_DATA as an indication of function availability.
+
+- Remove typecast
+
+- Fix comment
+
+- Add ares_data.c and ares_data.h
+
+- Jakub Hrozek modified ares_parse_srv_reply() and ares_parse_txt_reply() API
+  to return a linked lists of results. These were also modified to internally
+  use the ares_data memory struct and as such its result must be free'ed with
+  ares_free_data().
+
+- Initial support for the generic ares_free_data() function that will allow
+  applications to free memory allocated and returned by some c-ares funtions.
+
+- Make usage of calloc()'s arguments consistent with rest of code base
+
+- workaround icc 9.1 optimizer issue
+
+- Add icc fvisibility bug test
+
+- Fix icc 9.0 compiler warning: external definition with no prior declaration
+
+- Fix three var names
+
+- Add check for assert.h header file
+
+- getaddrinfo is fully thread safe on solaris versions which
+  implement the function even when h_errno is not a macro.
+  
+  The h_errno macro test now only done on systems for which there
+  is no hard coded knowledge about getaddrinfo's thread safeness.
+
+- Remove files generated on previous buildconf/configure run
+
+- Remove enable-thread / disable-thread configure option. These were only placebo
+  options. The library is always built as thread safe as possible on every system.
+
+- Refactor how preprocessor symbol _THREAD_SAFE definition is done.
+
+- Assume that getaddrinfo is thread safe, unless hard coded
+  knowledge says the contrary or h_errno is not defined.
+
+- Related with the threadsafe capability of getaddrinfo:
+  
+  - Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2
+    and newer have a threadsafe getaddrinfo.
+  
+  - Fix Dragonfly BSD triplet detection.
+  
+  - In case the hard-coded knowledge says that getaddrinfo is threadsafe,
+    an additional check is done to verify that h_errno is also defined.
+    If h_errno isn't defined, we finally assume that it isn't threadsafe.
+    Jamie Lokier provided the inspiration for this extra check.
+
+- AIX 5.2 and newer have threadsafe getaddrinfo.
+  
+  Add some comments to better understand what the regex's pretend to achieve.
+
+- HP-UX 11.11 and later have threadsafe getaddrinfo
+
+- Check if getaddrinfo is threadsafe when function check allows it to be used
+
+- Renamed fpGetNetworkParams and fpSystemFunction036 to avoid namespace pollution with static library

+- Ignore more subdirs

+- Fix compiler warning: conditional expression is constant
+
+- Sync linker and resource compiler options with Makefile.msvc
+
+- Follow Makefile.msvc subdirectory naming scheme, and sync compiler options
+
+- Updated MSVC makefile that allows building dynamic and static
+  c-ares libraries in debug and release flavours.
+  
+  Additionally each of the three sample programs is built against
+  each of the four possible c-ares libraries, generating all this
+  a total number of 12 executables and 4 libraries.
+
+- Test for USE_WINSOCK since it is more restrictive than WIN32
+
+- Make header inclusion depend on HAVE_*_H definition
+
+- Remove unneeded preprocessor directives
+
+- Adjust c-ares include paths for memory tracking enabled (--enable-curldebug) builds
+
+- source files used by sample programs
+
+- Renamed c-ares setup.h to ares_setup.h
+
+- Adjust include paths to take in account that currently:
+  
+  c-ares with --enable-curldebug uses memdebug.h from libcurl's lib subdirectory.
+  
+  memdebug.h needs access to libcurl's setup.h from libcurl's lib subdirectory
+  and also needs access to libcurl's generated curl_config.h
+
+- Undo old temporary change once used for testing purposes
+
+- Mention many changes
+
+- Mention --enable-symbol-hiding configure option
+
+- Symbol hiding configure options renamed to the hopefully less ambiguous
+  --enable-symbol-hiding and --disable-symbol-hiding as well as related
+  macro names and some internal variables used for them.
+  
+  Related configuration file preprocessor symbols named to
+  CARES_SYMBOL_HIDING and CARES_SYMBOL_SCOPE_EXTERN.
+
+- Header inclusion depending on HAVE_* symbol.
+  Fix two typos.
+
+- Comparison of the Initial revision of this file with ares_parse_a_reply.c
+  shows that this one is actually a modified copy of ares_parse_a_reply.c.
+  
+  In order to comply with ares_parse_a_reply.c's M.I.T. license, the old
+  1998 M.I.T. copyright notice is now also preserved in this file the same
+  as it is done in other ares_parse_*.c files.
+
+- Add CVS Id tag.
+  Fix identation of some license lines.
+
+- Add CVS Id tag.
+
+- Fix comment
+
+- In no particular order, changed/fixed all of the following in
+  ares_parse_txt_reply() current version:
+  
+  - Fixed a couple of potential double free's.
+  
+  - Fixed memory leaks upon out of memory condition.
+  
+  - Fixed pointer arithmetic.
+  
+  - Setting ntxtreply to zero upon entry for all failure cases.
+  
+  - Changed data type to size_t for variables substr_len, str_len and
+    the length member of ares_txt_reply struct.
+  
+  - Avoided a couple of memcpy() calls.
+  
+  - Changed i data type to unsigned int to prevent compiler warnings.
+  
+  - Adjusted a comment.

-  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.
+- Fix compiler warning: out of bound access
 
-  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.
+- fix compilation on AIX

-  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

+- Let's not call ares_save_options() deprecated just yet
 
-  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.

+  Also discussed on the ml.
 
-  Here's how I suggest we proceed with the API:
+Dan Fandrich (2 Dec 2008)

-  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.
+- Convert the public config struct to the same binary size/construct as in the
+  latest releases to remain ABI compatible.
 
-  ares_save_options() will continue to work like today, but will ONLY save

-  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.
+- Netware has gethostname()
 
-  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.

-* Aug 25 2008 (Yang Tse)
-- Improvement by Brad House:
+Gisle Vanem (12 Sep 2008)
+- djgpp does have strdup().
 
-  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.
+Yang Tse (12 Sep 2008)
+- change CRLF into LF line endings
 
-  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.
+- strdup() clone for systems/configurations which lack it
 
-- Fix by George Neill:
-  Fixed compilation of acountry sample application failure on some systems.
+- move inclusion of ares_private.h last
 
-* Aug 4 2008 (Daniel Stenberg)
-- Fix by Tofu Linden:
+- icc adjustments
 
-  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).
+- icc adjustments
 
-  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.
+- Select strict ANSI C89 conformance for icc
 
-  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.

+Yang Tse (4 Aug 2008)
 - 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.
+  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.
 
-* 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.
+- Adjust DEC/Compaq C compiler settings.
 
-- 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.
+- Another AC_TRY_LINK conversion to AC_LINK_IFELSE.
+  Proper definition of HAVE_function if function is found deeper.
 
-* 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.
+- Sync up with reality
 
-* 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.
+- Rename reentrant.m4 to avoid filename clash.
 
-* Jul 2 2008 (Yang Tse)
-- Fallback to gettimeofday when monotonic clock is unavailable at run-time.
+- Add file version serial number that might be used by 'aclocal' and others.
+  
+  Keep the '#' character as the first one on the line.
 
-* Jun 30 2008 (Daniel Stenberg)
+- Update copyright year.
 
-- 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.
+- Sync comment with reality.
 
-  I also fixed init_by_defaults() function to not leak memory in case if
-  error.
+- 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.
 
-* Jun 9 2008 (Yang Tse)
+- Add quoting for the AC_DEFINE arguments.
 
-- Make libcares.pc generated file for pkg-config include information relative
-  to the libraries needed for the static linking of c-ares.
+- Also remove the whitespace.
 
-* May 30 2008 (Yang Tse)
+- Also remove the extra quoting.
 
-- Brad House fixed a missing header file inclusion in adig sample program.
+- 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.
 
-Version 1.5.2 (May 29, 2008)
+- 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.
 
-* May 13 2008 (Daniel Stenberg)
+- for debugging purposes show ACLOCAL_FLAGS
 
-- Introducing millisecond resolution support for the timeout option. See
-  ares_init_options()'s ARES_OPT_TIMEOUTMS.
+- These lines were unintentionally removed in previous commit
 
-* May 9 2008 (Yang Tse)
+- Partially undo change that prevented SED, GREP, EGREP and AR from being changed by libtool or autoconf.
 
-- Use monotonic time source if available, for private function ares__tvnow()
+- Assert that SED and GREP are set
 
-* May 7 2008 (Daniel Stenberg)
+- Require autoconf 2.57 or newer
 
-- 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.
+- When calling aclocal, user defined ACLOCAL_FLAGS will now precede ours.
 
-- 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).
+- move ACLOCAL_AMFLAGS after AUTOMAKE_OPTIONS
 
-* May 5 2008 (Yang Tse)
+- setup.h handles definition of _REENTRANT based on NEED_REENTRANT
+  definition which might be defined in config.h or config-*.h files
 
-- Improved parsing of resolver configuration 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.
 
-* April 4 2008 (Daniel Stenberg)
+- 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.
 
-- Eino Tuominen improved the code when a file is used to seed the randomizer.
+- Explicitly include our m4 files first. This might minimize the impact
+  that other package's underquoted m4 function definitions have on ours.
 
-- Alexey Simak made adig support NAPTR records
+- Add a 3 argument check for getprotobyname_r
 
-- Alexey Simak fixed the VC dsp file by adding the missing source file
-  ares_expand_string.c
+- move reentrant.m4 to the m4 subdirectory to avoid infinite loop inclusion problem
 
-* December 11 2007 (Gisle Vanem)
+- add checks for strtok_r and getprotobyname_r
 
-- 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.
+- 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.
+  
+  Introduced reentrant.m4 intended for our reentrant related autotools/m4 macros.
 
-* December 3 2007 (Daniel Stenberg)
+- reorder argument number detection for getservbyport_r to
+  actually verify if the test is properly working
 
-- 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.
+- Make sure that configure process tests are done with the same _REENTRANT
+  setting as the one actually used when finally building the library.
 
-- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat
+- Change recvfrom's sixth argument data type to the 'historically standard' 'int'
+  data type for systems where this sixth argument is prototyped as a void pointer.
+  
+  Start of thread: http://curl.haxx.se/mail/lib-2008-07/0153.html
 
-Version 1.5.1 (Nov 21, 2007)
+- use prototypes to improve getservbyport_r detection
 
-* November 21 2007 (Daniel Stenberg)
+- Adjust recvfrom's sixth arg data type definition for NetWare (LIBC)
 
-- Robin Cornelius pointed out that ares_llist.h was missing in the release
-  archive for 1.5.0
+- Use the sreadfrom() wrapper to replace recvfrom() in our code.
 
-Version 1.5.0 (Nov 21, 2007)
+- when recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
+  now cause the definition of RECVFROM_TYPE_ARG2_IS_VOID, RECVFROM_TYPE_ARG5_IS_VOID
+  or RECVFROM_TYPE_ARG6_IS_VOID, as appropriate.
 
-* October 2 2007 (Daniel Stenberg)
+- Adjust DEC/Compaq C compiler settings
 
-- ares_strerror() segfaulted if the input error number was out of the currently
-  supported range.
+- Added "pointer to void" as another data type to check for the sixth argument of
+  function recvfrom as a result of the info additionally logged when running on a
+  Solaris system.
+  
+  The compiler error showed that the prototype being used on Solaris was the one
+  declared in line 427 of "/usr/include/sys/socket.h" as:
+  
+  function(int,
+           pointer to void,
+           unsigned int,
+           int,
+           pointer to struct sockaddr,
+           pointer to void) returning int
 
-- Yang Tse: Avoid a segfault when generating a DNS "Transaction ID" in
-  internal function init_id_key() under low memory conditions.
+- Adjust DEC/Compaq C compiler settings
 
-* September 28 2007 (Daniel Stenberg)
+- 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.
 
-- 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)
+- 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.
 
-* September 28 2007 (Steinar H. Gunderson)
+- Initial DEC/Compaq C compiler detection and flags
 
-- Don't skip a server if it's the only one. (Bugfix from the Google tree.)
+- Improved configure detection of number of arguments for getservbyport_r
 
-- 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.)
+- Allow --enable-largefile and --disable-largefile configurations.
+  Configure process no longer needs nor checks size of curl_off_t.
+  Library will now be built with _REENTRANT symbol defined.
 
-- Support a few more socket options: ARES_OPT_SOCK_SNDBUF and
-  ARES_OPT_SOCK_RCVBUF
+- fix compiler warning
 
-- 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.
+- since Jun 30 2008 MAXHOSTNAMELEN define is no longer used
 
-* September 22 2007 (Daniel Stenberg)
+- fix c-ares version reported in generated libcares.pc file when building
+  from CVS tree.
 
-- 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.
+- egrep and ar are also mandatory
 
-- 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.
+Daniel Stenberg (3 Jul 2008)
+- just to clarify that c-ares actually have some ipv6 support
 
-- Brad House provided a fix for ares_save_options():
+- ares_gethostbyname() fallback from AAA to A records with CNAME present
 
-  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.
+- - 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.
 
-* July 14 2007 (Daniel Stenberg)
+Yang Tse (2 Jul 2008)
+- The configure process will now halt when sed or grep are unavailable
 
-- Vlad Dinulescu fixed two outstanding valgrind reports:
+- fallback to gettimeofday when monotonic clock is unavailable at run-time
 
-  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.
+- IBM C/C++ compiler predefined macro check
 
-  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.
+- set earlier in configure process IBM compilers optimization flags
 
-  Even after declaring these variables as "unsigned short", the valgrind
-  errors are still there. Which brings us to the third problem.
+- make check message wording more precise
 
-  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:
+Daniel Stenberg (30 Jun 2008)

-        buffer_ptr[counter] ^= state[xorIndex];   (ares_query.c:62)
+Yang Tse (29 Jun 2008)
+- fix C style comment
 
-  This is what triggers Valgrind.. buffer_ptr is unitialised in this function,
-  and by applying ^= on it, it remains unitialised.
+- John Lightsey filed bug report #1999181: "CLOCK_MONOTONIC always fails on
+  some systems" (http://curl.haxx.se/bug/view.cgi?id=1999181). The problem was
+  that the configure script did not use the _POSIX_MONOTONIC_CLOCK feature test
+  macro when checking monotonic clock availability. This is now fixed and the
+  monotonic clock will not be used unless the feature test macro is defined
+  with a value greater than zero indicating always supported.
 
-Version 1.4.0 (June 8, 2007)
+- Modified configuration script to actually verify if the compiler is good
+  enough at detecting compilation errors or at least it has been properly
+  configured to do so. Configuration heavily depends on this capability, so
+  if this compiler sanity check fails the configuration process will now fail.

+- No longer break out of a shell "for" statement from inside
+  AC_FOO_IFELSE macros, otherwise temp files are not removed.
+  
+  Identation adjustment.
 
-- 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.
+Gunter Knauf (11 Jun 2008)
+- enable additional CFLAGS from commandline.
 
-  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.
+Yang Tse (9 Jun 2008)
+- fix pkg-config reporting of private libraries needed for static linking
 
-* June 2 2007
+- MSVC does build Windows native targets
 
-- Brad Spencer found and fixed three flaws in the code, found with the new
-  gcc 4.2.0 warning: -Waddress
+- Brad House fixed a missing header file inclusion in adig sample program
 
-- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
-  He also made recent Microsoft compilers use _strdup() instead of strdup().
+Daniel Stenberg (29 May 2008)
+- start working on 1.5.3
 
-- Brad House's man pages for ares_save_options() and ares_destroy_options()
-  were added.
+Version 1.5.2 (29 May 2008)
 
-- Ashish Sharma provided a patch for supporting multiple entries in the

-* May 30 2007
+Yang Tse (22 May 2008)
+- MSVC6+ clean-up targets must also remove acountry.exe
 
-- Shmulik Regev brought cryptographically secure transaction IDs:
+- sync with reality
 
-  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.
+- fix: [action-if-found] part of AC_CHECK_TYPE macro cannot be quoted when empty
 
-  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.
+- fix: remove need and definition of HAVE_SOCKLEN_T symbol
 
-  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.
+- fix: socklen_t definition comment
 
-  The patch can be tested by using the adig utility and using the '-s' option.
+- update several macros using AC_TRY_LINK with AC_LINK_IFELSE
 
-- 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.
+- fix underquoting of AC_LANG_PROGRAM arguments
 
-  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.
+- if'def out private function ares__tvdiff(), it is not in use yet.
 
-  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.
+- update several macros using AC_TRY_LINK with AC_LINK_IFELSE
 
-- 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.
+- fix socklen_t equivalent detection when cross compiling Windows target
 
-* May 25 2007
+- if WINSOCK2 API is used link with 'ws2_32', else
+  
+  if WINSOCK API is used under WinCE link with 'winsock', else
+  
+  if WINSOCK API is used link with 'wsock32'.
 
-- Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows
-  that could cause it to return a bad return code.
+- on winsock systems linking is done using library 'ws2_32' when
+  winsock2.h is available, and library 'winsock' is used when only
+  winsock.h is available.
 
-* April 16 2007
+- minor change for wince-cegcc and wince-mingw32ce support
 
-- Yang Tse: Provide ares_getopt() command-line parser function as a source
-  code helper function, not belonging to the actual c-ares library.
+- millisecond resolution support followup
 
-* February 19 2007
+Gisle Vanem (15 May 2008)
+- Replaced "-DHAVE_FIONBIO" with "-DHAVE_IOCTLSOCKET".
+  Added "-DHAVE_GETTIMEOFDAY". Trimmed lines.
 
-- Vlad Dinulescu added ares_parse_ns_reply().
+Yang Tse (15 May 2008)
+- sync with reality
 
-* February 13 2007
+- remove compilation time generated files
 
-- 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.
+- use same time source for timeout initialization and processing
 
-* November 22 2006
+- Improve toolchain detection for WinCE cross compilation:
+  
+  When cross compiling WinCE with the arm-wince-cegcc-gcc C compiler
+  symbol __CEGCC__ is defined and the unix-like compatibility layer
+  is used. For our purposes this is not a native Windows build.
+  
+  When cross compiling WinCE with the arm-wince-mingw32ce-gcc C compiler
+  symbol __MINGW32CE__ is defined and the unix-like compatibility layer
+  is not used. For our purposes this _is_ a native Windows build.
 
-- Install ares_dns.h too
+- skip checks for Windows specific header files
+  when build target is not a native Windows one
 
-- 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.
+- WinCE cross compilation adjustments:
+  
+  HAVE_WINSOCK2_H shall not be defined.
+  HAVE_WS2TCPIP_H shall not be defined.
 
-* November 6 2006
+Daniel Stenberg (13 May 2008)
+- - Introducing millisecond resolution support for the timeout option. See
+    ares_init_options()'s ARES_OPT_TIMEOUTMS.
 
-- Yang Tse removed a couple of potential zero size memory allocations.
+Yang Tse (13 May 2008)
+- also ignore this
 
-- 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...
+- also ignore this
 
-Version 1.3.2 (November 3, 2006)
+- ignore this compilation time generated files
 
-* October 12 2006
+- don't keep in CVS this compilation time generated file
 
-- Prevent ares_getsock() to overflow if more than 16 sockets are used.
+- add MSVC6 project for acountry sample program
 
-* September 11 2006
+- update MSVC6 projects to use the multithreaded DLL runtime library
 
-- 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.
+- add MSVC6 project for acountry sample program
 
-* August 29 2006
+- skip libtool C++ preprocessor compiler and linker checks
 
-- Brad Spencer did
+- ignore libcares.pc
 
-  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
+- configure script will now define HAVE_CLOCK_GETTIME_MONOTONIC symbol only
+  when function clock_gettime() is available and the monotonic timer is
+  also available. Otherwise, in some cases, librt or libposix4 could be used
+  for linking even when finally not using the clock_gettime() function due
+  to lack of the monotonic clock.
 
-* August 3 2006
+- fix syntax error: missing semicolon
 
-- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
-  not always zero!
+- Add library checking for clock_gettime() support
 
-Version 1.3.1 (June 24, 2006)
+- Use monotonic time source if available.
 
-* July 23, 2006
+Daniel Stenberg (9 May 2008)
+- Removed AC_PROG_CC_STDC again. It enforces C99/gnu99 stdandard which is too
+  liberal for me. Also, autoconf 2.61 and earlier doesn't work with icc 10.1
+  for this macro. (2.62 confirmed to work though). See discusson on the mailing
+  list starting here:
+  
+  http://daniel.haxx.se/projects/c-ares/mail/c-ares-archive-2008-05/0001.shtml
 
-- Gisle Vanem added getopt() to the ahost program. Currently accepts
-  only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
+- include strings.h (if available) for the strcasecmp() proto
 
-* June 19, 2006
+- check for strings.h in configure and use it for the strcasecmp() proto
 
-- (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).
+- adjusted to work with the updated configure.ac
+
+- - 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).
+
+Yang Tse (5 May 2008)
+- Improved parsing of resolver configuration files
+
+- make previous compiler warning fix more portable
+
+- fix compiler warning: indirection to slightly different base types
+
+- fix compiler warning: local variable may be used without having been initialized
+
+- fix compiler warning: unreferenced formal parameter
+
+- fix compiler warning: assignment within conditional expression
+
+Daniel Stenberg (4 Apr 2008)
+- - Alexey Simak fixed the VC dsp file by adding the missing source file
+    ares_expand_string.c
+
+- Alexey Simak made adig support NAPTR records
 
-* June 18, 2006
+- Eino Tuominen improved the code when a file is used to seed the randomizer
 
-- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
-  from area_process.c.
+Yang Tse (29 Feb 2008)
+- Force AIX xlc to fail and not generate object code if the source code has
+  compiled with errors. This behaviour is needed for autoconf macros which
+  rely on the ability to compile with or without errors, and is safer than
+  xlc's default of failing only upon severe errors.
 
-  TODO: Handle one last EAGAIN for a UDP socket send(2) in
-  ares__send_query().
+Gunter Knauf (27 Feb 2008)
+- added get_ver.awk since c-ares is a standalone project, and should therefore also compile when cURL is absent.
 
-* May 10, 2006
+- a couple of small fixes to the makefile:
+  fixed comments; fixed INSTDIR define, simplified rules;
+  changed to use get_ver.awk in current dir rather than the curl one.
 
-- 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.
+- fixed linker def file for tools when compiled with gcc/nlmconv.
 
-* May 3, 2006
+- added some files which were missing in release tarballs.
 
-- 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.
+- updated copyright for new year.
 
-* January 9, 2006
+Gisle Vanem (2 Jan 2008)
+- Added '-d' option for Watt-32 debugging.
 
-- Alexander Lazic improved the getservbyport_r() configure check.
+Yang Tse (18 Dec 2007)
+- MSVC 9.0 (VS2008) does not support Windows build targets prior to WinXP,
+  and makes wrong asumptions of build target when it isn't specified. So,
+  if no build target has been defined we will target WinXP when building
+  with MSVC 9.0 (VS2008).
 
-* January 6, 2006
+Daniel Stenberg (11 Dec 2007)
+- build acountry too
 
-- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
-  variable for easier controlling what it does and how it runs.
+Gisle Vanem (11 Dec 2007)
+- Added acountry.c.
 
-* January 5, 2006
+- Added build of acountry.nlm.
 
-- 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".
+- Added build of acountry.exe.
 
-* December 22
+- Build acountry.exe. Added 'socklen_t' define.
 
-- 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.
+- Another sample application that returns country-code and
+  name from an IPv4-address or host-name. Using the service of
+  countries.nerd.dk.
 
-* November 25
+Daniel Stenberg (10 Dec 2007)
+- grrr, the previous commit was meant to properly make sure that we don't
+  link any executables when doing debug builds since they kind of assume
+  symbols provided by libcurl, but it also wrongly included acountry.c
 
-- Yang Tse fixed some send() / recv() compiler warnings
+- when building
 
-* September 18
+- build ahost and adig by default but don't install them
 
-- Added constants that will be used by ares_getaddrinfo
+Gisle Vanem (10 Dec 2007)
+- Fix for targets that do have 'struct in6_addr', but which doesn't
+  define 's6_addr' as a macro.
 
-- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it
-  is available to ensure it works properly in a threaded environment.
+Yang Tse (3 Dec 2007)
+- Fix three issues previous cleanup introduces.
 
-* September 10
+Daniel Stenberg (3 Dec 2007)
+-  Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat
 
-- configure fix for detecting a member in the sockaddr_in6 struct which failed
-  on ipv6-enabled HP-UX 11.00
+- 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.
 
-Version 1.3.0 (August 29, 2005)
+- the gethostbyname fix applied here as well
 
-* August 21
+- fix next_lookup() to continue searching even if c-ares failed to load the
+  /etc/hosts file, pointed out by Erik Kline:
+  http://daniel.haxx.se/projects/c-ares/mail/c-ares-archive-2007-11/0027.shtml
 
-- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info()
-  when getting the DNS server etc.
+- Remove the check for libdl since that isn't actually used and it causes
+  warnings. Pointed out by Robin Cornelius.
 
-* June 19
+- pkgconfig fix by Andreas Schuldei
 
-- Added some checks for the addrinfo structure.
+- spellfix
 
-* June 2
+- and we start on 1.5.2!
 
-- William Ahern:
+Version 1.5.1 (21 Nov 2007)
 
-  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.)
+Daniel Stenberg (21 Nov 2007)
+- change
 
-  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.
+- oops
 
-* May 16
+- start working on 1.5.1 now
 
-- Added ares_getnameinfo which mimics the getnameinfo API (another feature
-  that could use testing).
+Version 1.5.0 (21 Nov 2007)
 
-* May 14
+Daniel Stenberg (21 Nov 2007)
+- this is what 1.5.0 is
 
-- Added an inet_ntop function from BIND for systems that do not have it.
+- fill in missing copyrights
 
-* April 9
+Gunter Knauf (18 Nov 2007)
+- removed now obsolete defines;
+  updated external library versions to latest.
 
-- Made sortlist support IPv6 (this can probably use some testing).
+Steinar H. Gunderson (16 Nov 2007)
+- Fix a double free.
 
-- Made sortlist support CIDR matching for IPv4.
+Yang Tse (15 Nov 2007)
+- Needed now that in6_addr is referenced in ares.h
 
-* April 8
+Steinar H. Gunderson (15 Nov 2007)
+- When looking up in DNS and then in the hosts file, return the error code from DNS if both fail, instead of returning the error code from the hosts file, as today. Patch from the Google tree.
 
-- 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.
+- Return TTL data from ares_parse_{a,aaaa}_reply, if the user is so inclined. Patch from the Google tree.
 
-- 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.
+Yang Tse (8 Nov 2007)
+- Define WIN32 when build target is Win32 API.
+  This also defines it for WinCE even though it is a subset of WIN32.
 
-* April 7
+- The only libraries actually needed for sample programs adig and
+  ahost are ws2_32.lib and advapi32.lib
 
-- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
-  OS X.
+- MSVC versions prior to VS2005 do not complain about portable C functions
 
-* April 5
+- Windows build targets have socklen_t definition in ws2tcpip.h but some
+  versions of ws2tcpip.h do not have the definition. It seems that when
+  the socklen_t definition is missing from ws2tcpip.h the definition for
+  INET_ADDRSTRLEN is also missing, and that when one definition is present
+  the other one also is available.
 
-- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
-  from BIND for systems that do not include these functions.
+Gunter Knauf (22 Oct 2007)
+- removed dependency on gettimeofday() since we use only 1 sec resolution here.
 
-* March 11, 2005
+Yang Tse (20 Oct 2007)
+- Fix compiler warning: conversion from "int" to "unsigned short" may lose significant bits
 
-- Dominick Meglio added ares_parse_aaaa_reply.c and did various
-  adjustments. The first little steps towards IPv6 support!
+- Fix message shown when detecting icc version
 
-* November 7
+- Avoid shadowing a global declaration
 
-- Fixed the VC project and makefile to use ares_cancel and ares_version
+- Renamed a variable to avoid shadowing a global declaration
 
-* October 24
+- Renamed internal function to avoid a variable shadowing it
 
-- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw.
-  This is now fixed.
+- Fix compiler warning: feupdateenv is not implemented and will always fail.
+  Specifically for linux x86-64 with Intel's icc.
 
-Version 1.2.1 (October 20, 2004)
+- Sync PLATFORM_AIX_V3 detection and CURL_CC_DEBUG_OPTS()
+  icc warning level with libcurl's
 
-* September 29
+- Fix compiler warning: conversion from "int" to "unsigned char"
+  may lose significant bits
 
-- 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.
+- actually sync with lib/setup_once.h
 
-- Now c-ares will use local host name lookup _before_ DNS resolving by default
-  if nothing else is told.
+- sync with lib/setup_once.h
 
-* September 26
+Steinar H. Gunderson (16 Oct 2007)
+- Fix a bug where fallback from AF_INET6 to AF_INET would not work properly together with relative search; if you had a search path of .a.com and .b.com, and foo.a.com would return ARES_ENODATA and foo.b.com would return ARES_ENOTFOUND, the lookup would not properly retry with AF_INET as it forgot the first ARES_ENODATA.
 
-- 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.
+Dan Fandrich (15 Oct 2007)
+- Mention first version with CURLOPT_COPYPOSTFIELDS.
+  Don't confuse NUL with NULL.
 
-  c-ares now looks at
+Gisle Vanem (8 Oct 2007)
+- Added needed 'HAVE_*' defines.
 
-  1) resolv.conf (for the "lookup" line);
-  2) nsswitch.fon (for the "hosts:" line);
-  3) host.conf (for the "order" line).
+- 'FD_CLOXEC' is meaningless on MSDOS/Watt-32.
 
-  First match wins.
+Steinar H. Gunderson (4 Oct 2007)
+- Removed a piece of redundant code (process_answer already takes care of it).
 
-- 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.
+- Another timeout fix in ares_getnameinfo().
 
-  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
+- Send the timeout count in ares_getnameinfo().
 
-  The patch will make c-ares correctly consult the registry for the location
-  of this file.
+- Moved the NULL check for channel upwards in ares_destroy().
 
-* August 29
+- Clarified the comment over ares_cancel.
 
-- Gisle Vanem fixed the MSVC build files.
+Yang Tse (2 Oct 2007)
+- Avoid a segfault when generating a DNS "Transaction ID" in internal
+  function init_id_key() under low memory conditions.
 
-* August 20
+- Add ares_llist.c and ares_llist.h to MSCV project file.
 
-- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
+Daniel Stenberg (2 Oct 2007)
+- Fixed the problem where next_lookup would use 'status' uninitialized. Now
+  it gets passed the initial value as an argument.
 
-* August 13
+Yang Tse (2 Oct 2007)
+- Avoid inline C99ism, and move c-ares routines for managing doubly-linked lists.
 
-- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
-  fine with MSVC 7.1
+Daniel Stenberg (1 Oct 2007)
+- ares_strerror() segfaulted if the input error number was out of the currently
+  supported range.
 
-* July 24
+- Prevent ares_strerror() from segfaulting if an invalid error code is passed
+  in as argument!
 
-- Made the lib get built static only if --enable-debug is used.
+Yang Tse (30 Sep 2007)
+- Fix compiler warning
 
-- Gisle Vanem fixed:
+- check availability of <netinet/tcp.h>
 
-  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.
+- improve portability, defining MAXDNAME and MAXCDNAME
 
-  The next problem was that 'server->tcp_buffer_pos' had a random value at
-  entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
+Steinar H. Gunderson (30 Sep 2007)
+- Fix a memory leak that I recently inadvertedly introduced.
 
-  I've also added a ares_writev() for Windows to streamline the code a bit
-  more.
+- Use ISDIGIT instead of isdigit; fixes a gcc warning.
 
-* 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.
+- Port the TCP socket fix made in ares_fds() to ares_getsock() as well.
 
-- Made configure create config.h, and all source files now include setup.h that
-  might include the proper config.h (or a handicrafted alternative).
+- Previously, processing a large batch of timeouts was O(n^2) in the number of
+  outstanding queries, and processing a DNS response packet was O(n) in the
+  number of outstanding queries. To speed things up in Google, we added a few circular,
+  doubly-linked lists of queries that are hash-bucketed based on
+  the attributes we care about, so most important operations are now O(1).
+  
+  It might be that the number of buckets are higher than most people would need,
+  but on a quick calculation it should only be 100kB or so even on a 64-bit
+  system, so I've let it stay as-is.
 
-- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
-  use 'int' for that.
+Gisle Vanem (29 Sep 2007)
+- We should standarise on C comments.
 
-- 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!)
+- Fix compiler warning in setsockopt().
 
-- 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.
+Steinar H. Gunderson (29 Sep 2007)
+- TCP queries can time out too, not just UDP queries. (Patch from the Google tree.)
 
-- Adjusted 'maketgz' to use the new automake magic when building distribution
-  archives.
+- Read and process as many packets as possible in read_udp_packets, to avoid having to run the entire event loop once per packet. (Patch from the Google tree.)
 
-- Anyone desires HTML and/or PDF versions of the man pages in the release
-  archives?
+- There are two different places in write_tcp_data() that advance the send_queue; however, they are slightly different and only the first one properly uses a while loop. Consolidate both into a single function that DTTR. (Patch from the Google tree.)
 
-* July 3
-- Günter Knauf made c-ares build and run on Novell Netware.
+- Reject names that are longer than 255 characters, to avoid problems with strict or buggy DNS server implementations. (Patch from the Google tree)
 
-* 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.
+- In ares_mkquery, make sure we set buflen and buf to reasonable values if there's an error. (Patch from the Google tree)
 
-* June 30
-- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.
+- Be stricter about what's a valid IP address in fake_hostent. (Patch from the Google tree.)
 
-* June 10
-- Gisle Vanem's init patch for Windows:
+- Handle the root of the DNS tree correctly in ares_expand_name.
 
-  The init_by_resolv_conf() function fetches the DNS-server(s)
-  from a series of registry branches.
+Daniel Stenberg (28 Sep 2007)
+- today's modifications by Steinar and me
 
-  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.
+- 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)
 
-  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).
+Steinar H. Gunderson (28 Sep 2007)
+- Unrevert previous 'missing' hunks. They were missing since the patch is still in for review :-)
 
-  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.
+- Yet more missing hunks... Nggh.
 
-* June 8
-- James Bursa fixed an init issue for RISC OS.
+- 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.
 
-* 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.
+- Forgot to include a few hunks from ares_process.c earlier. Fixing now.
 
-  This is now adjusted in the code
+- Support a few more socket options, and refactor the option setting a bit. (Patch from the Google tree.)
 
-Version 1.2.0 (April 13, 2004)
+- Make the query callbacks return the number of timeouts that happened during the execution of a query, and update documentation accordingly. (Patch from the Google tree.)
 
-* April 2, 2004
-- Updated various man pages to look nicer when converted to HTML on the web
-  site.
+- Three fixes in one commit (sorry): a) Take care of the tcpbuf if it ends while queued for transmission, note broken servers and close them in the main loop, and store TCP socket generation number in order not to send the same query twice over the same socket.
 
-* 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.
+- Don't skip a server if it's the only one. (Bugfix from the Google tree.)
 
-- Dominick Meglio cleaned up the formatting in several man pages.
+Daniel Stenberg (27 Sep 2007)
+- wrong, revert the previous "fix" and instead check that the fd_set pointer
+  is non-NULL before we FD_CLR
 
-* March 30, 2004
-- Dominick Meglio's new ares_expand_string. A helper function when decoding
-  incoming DNS packages.
+- eek, fix the conditions to return on either problem instead of requiring
+  both to occur
 
-- 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.
+- 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.
 
-Version 1.1.0 (March 11, 2004)
+- 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.
 
-* March 9, 2004
-- Gisle Vanem improved build on Windows.
+- 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.
 
-* February 25, 2004
-- Dan Fandrich found a flaw in the Feb 22 fix.
+- added initial pkg-config file (attempt)
 
-- Added better configure --enable-debug logic (taken from the curl configure
-  script). Added acinclude.m4 to the tarball.
+Gunter Knauf (20 Jul 2007)
+- added curl include for debug builds.
 
-* February 23, 2004
-- Removed ares_free_errmem(), the function, the file and the man page. It was
-  not used and it did nothing.
+Daniel Stenberg (14 Jul 2007)
+- added another SEE ALSO
 
-- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
-  compiler warnings on picky compilers.
+- Brad House's fix to hish a win32 compiler warning
 
-* February 22, 2004
-- Dominick Meglio made ares init support multiple name servers in the
-  NameServer key on Windows.
+- added Vlad's entire description of his valgrind fix
 
-* 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.
+- Vlad Dinulescu fixed two outstanding valgrind reports
 
-- Made the makefile only build ahost and adig if 'make demos' is used.
+Gunter Knauf (8 Jul 2007)
+- added better CodeWarrior detection.
 
-* February 10, 2004
-- Dirk Manske made ares_version.h installed with 'make install'
+- removed some obsolete include paths and defines.
 
-* 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
+- add test for gettimeofday() so that HAVE_GETTIMEOFDAY gets defined.
 
-Version 1.0.0 (February 3, 2004)
+- although the check for HAVE_STRUCT_TIMEVAL solved the redefine it is incorrect; lets see if a check for HAVE_GETTIMEOFDAY also works; if gettimeofday() is present then we can assume we have the timezone struct too.
 
-* February 3, 2004
-- now we produce the libcares.a library instead of the previous libares.a
-  since we are no longer compatible
+- added check for sys/param.h.
 
-* February 2, 2004
+- trial to catch problem with Daniels cross-mingw ares builds.
 
-- ares_strerror() has one argument less. This is the first official
-  modification of the existing provided ares API.
+- added NetWare CLIB-own header to solve gcc warnings.
 
-* January 29, 2004
+- few minor changes to make ares compile for NetWare CLIB architecture.
 
-- Dirk Manske fixed how the socket is set non-blocking.
+- changed to build for CLIB / LIBC.
 
-* January 4, 2004
+- sync'd with lib makefile changes: use var for awk; fixed RECV* / SEND* defines; debug var can be overwritten; added better compiler path handling.
 
-- 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.
+Daniel Stenberg (8 Jun 2007)
+- start working on 1.4.1
 
-* October 24, 2003. Daniel Stenberg
+Version 1.4.0 (8 Jun 2007)
 
-  Added ares_version().
+Daniel Stenberg (8 Jun 2007)
+- 1.4.0 preps
 
-Version 1.0-pre1 (8 October 2003)
+- the revert
 
-- James Bursa made it run on RISC OS
+- Revered Ashish Sharma's multiple entries patch, as it caused memory madness
 
-- Dominick Meglio made it run fine on NT4
+- minor edit since getting an ID seems pointless when failure happens
 
-- Duncan Wilcox made it work fine on Mac OS X
+- fix the bad bad bad mess this caused on name resolves returning more than
+  one name... Reported by James Bursa
 
-- Daniel Stenberg adjusted the windows port
+- Brad Spencer found and fixed three flaws in the code, found with the new
+  gcc 4.2.0 warning: -Waddress
 
-- liren at vivisimo.com made the initial windows port
+- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
+  He also made recent Microsoft compilers use _strdup() instead of strdup().
 
-* Imported the sources from ares 1.1.1
+- Ashish Sharma provided a patch for supporting multiple entries in the
+  /etc/hosts file. Patch edited for coding style and functionality by me
+  (Daniel).

+                                How To Compile
+
+Installing Binary Packages
+==========================
+
+   Lots of people download binary distributions of c-ares. This document
+   does not describe how to install c-ares using such a binary package.
+   This document describes how to compile, build and install c-ares from
+   source code.
+
+Building from git
+=================
+
+   If you get your code off a git repository, see the GIT-INFO file in the
+   root directory for specific instructions on how to proceed.
+
+UNIX
+====
+   A normal unix installation is made in three or four steps (after you've
+   unpacked the source archive):
+
+        ./configure
+        make
+        make ahost adig acountry (optional)
+        make install
+
+   You probably need to be root when doing the last command.
+
+   If you have checked out the sources from the git repository, read the
+   GIT-INFO on how to proceed.
+
+   Get a full listing of all available configure options by invoking it like:
+
+        ./configure --help
+
+   If you want to install c-ares in a different file hierarchy than /usr/local,
+   you need to specify that already when running configure:
+
+        ./configure --prefix=/path/to/c-ares/tree
+
+   If you happen to have write permission in that directory, you can do 'make
+   install' without being root. An example of this would be to make a local
+   install in your own home directory:
+
+        ./configure --prefix=$HOME
+        make
+        make install
+
+   MORE OPTIONS
+   ------------
+
+     To force configure to use the standard cc compiler if both cc and gcc are
+     present, run configure like
+
+       CC=cc ./configure
+         or
+       env CC=cc ./configure
+
+     To force a static library compile, disable the shared library creation
+     by running configure like:
+
+       ./configure --disable-shared
+
+     If you're a c-ares developer and use gcc, you might want to enable more
+     debug options with the --enable-debug option.
+
+   SPECIAL CASES
+   -------------
+   Some versions of uClibc require configuring with CPPFLAGS=-D_GNU_SOURCE=1
+   to get correct large file support.
+
+   The Open Watcom C compiler on Linux requires configuring with the variables:
+
+       ./configure CC=owcc AR="$WATCOM/binl/wlib" AR_FLAGS=-q \
+           RANLIB=/bin/true STRIP="$WATCOM/binl/wstrip" CFLAGS=-Wextra
+
+
+Win32
+=====
+
+   Building Windows DLLs and C run-time (CRT) linkage issues
+   ---------------------------------------------------------
+
+   As a general rule, building a DLL with static CRT linkage is highly
+   discouraged, and intermixing CRTs in the same app is something to
+   avoid at any cost.
+
+   Reading and comprehension of Microsoft Knowledge Base articles
+   KB94248 and KB140584 is a must for any Windows developer. Especially
+   important is full understanding if you are not going to follow the
+   advice given above.
+
+   KB94248  - How To Use the C Run-Time
+              http://support.microsoft.com/kb/94248/en-us
+
+   KB140584 - How to link with the correct C Run-Time (CRT) library
+              http://support.microsoft.com/kb/140584/en-us
+
+   KB190799 - Potential Errors Passing CRT Objects Across DLL Boundaries
+              http://msdn.microsoft.com/en-us/library/ms235460
+
+   If your app is misbehaving in some strange way, or it is suffering
+   from memory corruption, before asking for further help, please try
+   first to rebuild every single library your app uses as well as your
+   app using the debug multithreaded dynamic C runtime.
+
+   MingW32
+   -------
+
+   Make sure that MinGW32's bin dir is in the search path, for example:
+
+     set PATH=c:\mingw32\bin;%PATH%
+
+   then run 'make -f Makefile.m32' in the root dir.
+
+   Cygwin
+   ------
+
+   Almost identical to the unix installation. Run the configure script in the
+   c-ares root with 'sh configure'. Make sure you have the sh executable in
+   /bin/ or you'll see the configure fail toward the end.
+
+   Run 'make'
+
+   Dev-Cpp
+   -------
+
+   See the separate INSTALL.devcpp file for details.
+
+   MSVC 6 caveats
+   --------------
+
+   If you use MSVC 6 it is required that you use the February 2003 edition PSDK:
+   http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm
+
+   MSVC from command line
+   ----------------------
+
+   Run the 'vcvars32.bat' file to get a proper environment. The
+   vcvars32.bat file is part of the Microsoft development environment and
+   you may find it in 'C:\Program Files\Microsoft Visual Studio\vc98\bin'
+   provided that you installed Visual C/C++ 6 in the default directory.
+
+   Further details in README.msvc
+
+   MSVC IDES
+   ---------
+
+   Details in README.msvc
+
+   Important static c-ares usage note
+   ----------------------------------
+
+   When building an application that uses the static c-ares library, you must
+   add '-DCARES_STATICLIB' to your CFLAGS.  Otherwise the linker will look for
+   dynamic import symbols.
+
+
+IBM OS/2
+========
+   Building under OS/2 is not much different from building under unix.
+   You need:
+
+      - emx 0.9d
+      - GNU make
+      - GNU patch
+      - ksh
+      - GNU bison
+      - GNU file utilities
+      - GNU sed
+      - autoconf 2.13
+
+   If during the linking you get an error about _errno being an undefined
+   symbol referenced from the text segment, you need to add -D__ST_MT_ERRNO__
+   in your definitions.
+
+   If you're getting huge binaries, probably your makefiles have the -g in
+   CFLAGS.
+
+
+QNX
+===
+   (This section was graciously brought to us by David Bentham)
+
+   As QNX is targeted for resource constrained environments, the QNX headers
+   set conservative limits. This includes the FD_SETSIZE macro, set by default
+   to 32. Socket descriptors returned within the c-ares library may exceed this,
+   resulting in memory faults/SIGSEGV crashes when passed into select(..)
+   calls using fd_set macros.
+
+   A good all-round solution to this is to override the default when building
+   c-ares, by overriding CFLAGS during configure, example
+   #  configure CFLAGS='-DFD_SETSIZE=64 -g -O2'
+
+
+RISC OS
+=======
+   The library can be cross-compiled using gccsdk as follows:
+
+        CC=riscos-gcc AR=riscos-ar RANLIB='riscos-ar -s' ./configure \
+             --host=arm-riscos-aof --without-random --disable-shared
+        make
+
+   where riscos-gcc and riscos-ar are links to the gccsdk tools.
+   You can then link your program with c-ares/lib/.libs/libcares.a
+
+
+NetWare
+=======
+   To compile libcares.a / libcares.lib you need:
+   - either any gcc / nlmconv, or CodeWarrior 7 PDK 4 or later.
+   - gnu make and awk running on the platform you compile on;
+     native Win32 versions can be downloaded from:
+     http://www.gknw.net/development/prgtools/
+   - recent Novell LibC SDK available from:
+     http://developer.novell.com/ndk/libc.htm
+   - or recent Novell CLib SDK available from:
+     http://developer.novell.com/ndk/clib.htm
+
+   Set a search path to your compiler, linker and tools; on Linux make
+   sure that the var OSTYPE contains the string 'linux'; set the var
+   NDKBASE to point to the base of your Novell NDK; and then type
+   'make -f Makefile.netware' from the top source directory;
+
+
+Android
+=======
+   Method using a configure cross-compile (tested with Android NDK r7b):
+      - prepare the toolchain of the Android NDK for standalone use; this can
+        be done by invoking the script:
+        ./tools/make-standalone-toolchain.sh
+        which creates a usual cross-compile toolchain. Lets assume that you put
+        this toolchain below /opt then invoke configure with something like:
+        export PATH=/opt/arm-linux-androideabi-4.4.3/bin:$PATH
+        ./configure --host=arm-linux-androideabi [more configure options]
+        make
+      - if you want to compile directly from our GIT repo you might run into
+        this issue with older automake stuff:
+        checking host system type...
+        Invalid configuration `arm-linux-androideabi':
+        system `androideabi' not recognized
+        configure: error: /bin/sh ./config.sub arm-linux-androideabi failed
+        this issue can be fixed with using more recent versions of config.sub
+        and config.guess which can be obtained here:
+        http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree
+        you need to replace your system-own versions which usually can be
+        found in your automake folder:
+        find /usr -name config.sub
+
+
+CROSS COMPILE
+=============
+   (This section was graciously brought to us by Jim Duey, with additions by
+   Dan Fandrich)
+
+   Download and unpack the c-ares package.
+
+   'cd' to the new directory. (e.g. cd c-ares-1.7.6)
+
+   Set environment variables to point to the cross-compile toolchain and call
+   configure with any options you need.  Be sure and specify the '--host' and
+   '--build' parameters at configuration time.  The following script is an
+   example of cross-compiling for the IBM 405GP PowerPC processor using the
+   toolchain from MonteVista for Hardhat Linux.
+
+   (begin script)
+
+   #! /bin/sh
+
+   export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin
+   export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include"
+   export AR=ppc_405-ar
+   export AS=ppc_405-as
+   export LD=ppc_405-ld
+   export RANLIB=ppc_405-ranlib
+   export CC=ppc_405-gcc
+   export NM=ppc_405-nm
+
+   ./configure --target=powerpc-hardhat-linux \
+        --host=powerpc-hardhat-linux \
+        --build=i586-pc-linux-gnu \
+        --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local \
+        --exec-prefix=/usr/local
+
+   (end script)
+
+   You may also need to provide a parameter like '--with-random=/dev/urandom'
+   to configure as it cannot detect the presence of a random number
+   generating device for a target system.  The '--prefix' parameter
+   specifies where c-ares will be installed.  If 'configure' completes
+   successfully, do 'make' and 'make install' as usual.
+
+   In some cases, you may be able to simplify the above commands to as
+   little as:
+
+       ./configure --host=ARCH-OS
+
+
+PORTS
+=====
+   This is a probably incomplete list of known hardware and operating systems
+   that c-ares has been compiled for. If you know a system c-ares compiles and

+.TH ARES_CREATE_QUERY 3 "17 Aug 2012"
+.SH NAME
+ares_create_query \- Compose a single-question DNS query buffer
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_create_query(const char *\fIname\fP, int \fIdnsclass\fP,\
+                         int \fItype\fP,
+.B		                   unsigned short \fIid\fP, int \fIrd\fP,\
+                         unsigned char **\fIbuf\fP,
+.B		                   int *\fIbuflen\fP, int \fImax_udp_size\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_create_query
+function composes a DNS query with a single question.
+The parameter
+.I name
+gives the query name as a NUL-terminated C string of period-separated
+labels optionally ending with a period; periods and backslashes within
+a label must be escaped with a backlash.  The parameters
+.I dnsclass
+and
+.I type
+give the class and type of the query using the values defined in
+.BR <arpa/nameser.h> .
+The parameter
+.I id
+gives a 16-bit identifier for the query.  The parameter
+.I rd
+should be nonzero if recursion is desired, zero if not.  The query
+will be placed in an allocated buffer, a pointer to which will be
+stored in the variable pointed to by
+.IR buf ,
+and the length of which will be stored in the variable pointed to by
+.IR buflen .
+It is the caller's responsibility to free this buffer using
+\fIares_free_string(3)\fP when it is no longer needed.
+The parameter
+.I max_udp_size
+should be nonzero to activate EDNS. Usage of \fIares_create_query(3)\fP\ with
+.I max_udp_size
+set to zero is equivalent to \fIares_mkquery(3)\fP.
+.SH RETURN VALUES
+.B ares_create_query
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+Construction of the DNS query succeeded.
+.TP 15
+.B ARES_EBADNAME
+The query name
+.I name
+could not be encoded as a domain name, either because it contained a
+zero-length label or because it contained a label of more than 63
+characters.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.
+.SH AVAILABILITY
+Added in c-ares 1.10.0
+.SH SEE ALSO
+.BR ares_expand_name (3),
+.BR ares_free_string (3)

+.fi
+.SH DESCRIPTION
+This is a portable version with the identical functionality of the commonly
+available \fIinet_ntop\fP.
+
+The ares_inet_ntop() function converts a numeric address into a text string
+suitable for presentation. The \fBaf\fP argument shall specify the family of
+the address. This can be AF_INET or AF_INET6.  The \fBsrc\fP argument points
+to a buffer holding an IPv4 address if the af argument is AF_INET, or an IPv6
+address if the af argument is AF_INET6; the address must be in network byte
+order. The \fBdst\fP argument points to a buffer where the function stores the
+resulting text string; it shall not be NULL. The \fBsize\fP argument specifies
+the size of this buffer, which shall be large enough to hold the text string
+(INET_ADDRSTRLEN (16) characters for IPv4, INET6_ADDRSTRLEN (46) characters
+for IPv6).

+.SH DESCRIPTION
+This is a portable version with the identical functionality of the commonly

+The ares_inet_pton() function converts the address in its standard text

+(32 bits for AF_INET, 128 bits for AF_INET6).

+dnl -------------------------------------------------
+dnl Public macro.
+dnl
+dnl This macro emits shell code which does some
+dnl very basic checks related with the availability
+dnl of some commands and utilities needed to allow
+dnl configure script bootstrapping itself when using
+dnl these to figure out other settings. Also emits
+dnl code that performs PATH_SEPARATOR auto-detection
+dnl and sets its value unless it is already set with
+dnl a non-empty value.
+dnl
+dnl These basic checks are intended to be placed and
+dnl executed as early as possible in the resulting
+dnl configure script, and as such these must be pure
+dnl and portable shell code.
+dnl
+dnl This macro may be used directly, or indirectly
+dnl when using other macros that AC_REQUIRE it such
+dnl as XC_CHECK_PATH_SEPARATOR.
+dnl
+dnl Currently the mechanism used to ensure that this
+dnl macro expands early enough in generated configure
+dnl script is making it override autoconf and libtool
+dnl PATH_SEPARATOR check.

+dnl Emits shell code that computes the path separator

+dnl
+dnl Strictly speaking the check is done in two steps. The
+dnl first, which does the actual check, takes place in
+dnl XC_CONFIGURE_PREAMBLE macro and happens very early in
+dnl generated configure script. The second one shows and
+dnl logs the result of the check into config.log at a later
+dnl configure stage. Placement of this second stage in
