- RELEASE-NOTES: two more bug fixes
- [Keith Shaw brought this change]
ares_set_servers_csv: fixed IPv6 address parsing
Fixed bug that caused the last part of an IPv6 address to be parsed as
the port number when the last part is all numeric.
- nroff: fix two syntax mistakes
ares_parse_a_reply and ares_parse_aaaa_reply both had two \fB instead of
\fP
Reported-by: Alexander Klauer

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]
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.
- [Alexander Klauer brought this change]
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.
- [Alexander Klauer brought this change]
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().
- [Patrick Valsecchi brought this change]
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.

.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

- Set initial IFS to space, tab and newline.
- zz40-xc-ovr.m4: fix 'wc' detection

- 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

- 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.
- ares_parse_aaaa_reply: fix memory leak
an allocated buffer was not freed in the successful case.
- [Gisle Vanem brought this change]
adig: perror() doesn't work for socket errors on windows
... so print the SOCKERRNO instead
- get_DNS_AdaptersAddresses: fix IPv6 parsing
Use of the wrong define made the function not parse IPv6 addresses
properly.

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.
Yang Tse (29 Jun 2012)
- cares-compilers.m4: remove -Wstrict-aliasing=3 from clang
Currently it is unknown if there is any version of clang that
actually supports -Wstrict-aliasing. What is known is that there
are several that don't support it.
- cares-compilers.m4: -Wstrict-aliasing=3 for warning enabled gcc and clang builds

Yang Tse (14 Jun 2012)
- Kill compiler warning
- Fix libcares.pc generation for static MingW* cross builds
Daniel Stenberg (21 May 2012)
- [Nick Alcock brought this change]
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.

- Handle CNAME-only in ares_parse_aaaa_reply().
posted to the c-ares list by Peter Griess <pg@std.in>.
- Add support for multiple DNS servers on Android.
Before, c-ares always used the first DNS server on Android, causing
network problems if this DNS server was not available.
Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
- Added INSTALL so it gets into tarballs.
- Added some more ifdefs to silent compiler warnings.
Yang Tse (17 Apr 2012)
- INSTALL: remove a non c-ares section
- cares-compilers.m4: -Wno-pedantic-ms-format for Windows gcc 4.5 builds
When building a Windows target with gcc 4.5 or newer and strict compiler
warnings enabled use -Wno-pedantic-ms-format in addition to other flags.
- setup_once.h: tighten requirements for stdbool.h header inclusion
Include stdbool.h only when it is available and configure is capable of
detecting a proper 'bool' data type when the header is included.
- configure: NATIVE_WINDOWS no longer defined in config file
- cares-compilers.m4: double underscore decoration for visibility attribute
- build adjustments: CARES_SYMBOL_HIDING no longer defined in config files
configure script now provides conditional definitions for Makefile.am
that result in CARES_SYMBOL_HIDING being defined by resulting makefiles
when appropriate.
- configure: Windows cross-compilation fixes
CARES_BUILDING_LIBRARY and CARES_STATICLIB no longer defined in ares_config.h,
configure will generate appropriate conditionals so that mentioned symbols
get defined and used in Makefile derived from Makefile.am at compilation time.

get_iphlpapi_dns_info: fix buffer overrun
I experienced a buffer overrun exception in c-ares on Windows and
tracked it down to be an error in the calculation of the 'left' variable

ares_iphlpapi.h: Watcom C fix
Added "!defined(_WS2DEF_)" since Watcom doesn't have
a per type guard for the typedefs 'CSADDR_INFO' (that MingW has) or
'SOCKET_ADDRESS' (that MSVC has). But we can use the header-guard for
<ws2def.h> instead.
- [Gisle Vanem brought this change]
Makefile.Watcom:
* The 'NTDDI_VERSION' needs to be raised to 0x05010000
in order for SOCKADDR_STORAGE etc. to be typedefed.
* Replaced '-dUSE_WATT32' with '-dWATT32'.
* Added $(DEMOS) to the 'all' target and removed the 'demos'
target to be consistent with e.g. Makefile.msvc etc.
* 'ENABLE_IPV6' is no longer used. Hence removed the '%use_ipv6' construct.
* object-file order seems to be important (Watcom v.19). Hence
'ares_getopt.obj' must be put after the .obj that references getopt().
- cares-compilers.m4: CARES_CONVERT_INCLUDE_TO_ISYSTEM adjustments

- getservbyport replacement for Win CE
- renamed getplatform() to ares__getplatform() to avoid namespace pollution
- configure: fix libtool warning
Recent versions of libtool are now tracing usage of AC_CONFIG_MACRO_DIR
macro and warn heavily when not used in configure script along with
ACLOCAL_AMFLAGS in Makefile.am. So in order to make libtool happy
while keeping backwards compatibility this is added.
- adig: RFC4034 resource record type detection
Can be tested with: adig -s 8.8.8.8 -t ANY example.com
- nameser.h: RFC4034 resource record type definitions
- build: move platform stuff to ares_platform.c and ares_platform.h
- build: find out windows platform using GetVersionEx()
- build: use getenv() replacement function for systems which lack it
- setup_once: system error codes for Windows CE
- ares_search: use ERRNO macro for portability sake
- System's errno.h inclusion cleanup follow-up.
System's errno.h is conditionally included from setup_once.h
- Windows CE specific adjustment
All versions of Windows CE support Winsock 1.1
- System's errno.h inclusion cleanup.
System's errno.h is conditionally included from setup_once.h
- ares_init: fix gethostname error detection on winsock platforms
- configure: r-enable temporarily disabled detection of system's inet_ntop()
Detection was temporarily disabled in commit 674e044ccb21f2f63537da53565fce868f

- configure: stop using the deprecated AM_INIT_AUTOMAKE syntax
- [Gisle Vanem brought this change]
Watt-32: use errno
Make sure Watt-32 programs use 'errno' even on Win32 targets
Guenter Knauf (18 Feb 2011)
- Removed commented CLFAGS no longer needed.
- Fixed CFLAGS for NetWare.
Added -m32 to enable compilation with x86_64 compilers;
added conditional to set -fpcc-struct-return only for gcc compiler.

Watt32: fix server init
Somewhere in the process, programs using the Watt-32 tcp/ip stack
stopped working.
- [Dima Tisnek brought this change]
config_sortlist: (win32) missing else
Without an else there, contents of "pat" that could have been
successfully set just above, may be clobbered by successive unsuccessful
calls to "xxx_pton" or "ip_addr".
Yang Tse (17 Jan 2011)
- Makefile.msvc: add a couple of VS version strings
- Makefile.msvc: add a couple of VS version strings
- build: add install target to Makefile.msvc
Daniel Stenberg (27 Dec 2010)
- ares_set_servers_csv: remove unused variables
- init_by_resolv_conf: fix compiler warnings
The code received the return codes in the 'status' variable without
using it. Instead we just ignore those particular errors.
- getv4: Value stored to 'dst' is never read
- advance_tcp_send_queue: avoid NULL ptr dereference
If given a too large 'num_bytes' value, it would cause a NULL ptr
dereference. Instead the code will now break out of the loop at the end
of the list.
- [Peter Pentchev brought this change]
configure: fix a bashism
- cleanup: avoid unsafe typecasts
Avoid the risk of reading 16bit data from an unaligned address by using
a macro that is adapted for this.
- [Stefan Bühler brought this change]
ares_expand_name: Fix encoded length for indirect root
Yang Tse (18 Dec 2010)
- build: add some explicit file references to VS project files
- config-win32: provide HAVE_ASSERT_H definition
- build: include ares_nowarn in sample program VS project files
- build: include ares_nowarn among SAMPLESOURCES and SAMPLEHEADERS
- configure: temporarily disable detection of system's inet_ntop()
This is done to allow compilation of ares_inet_ntop() by some daily
builds picky compilers that otherwise do not need this function.
- changes: mention last fix
- ares_inet_ntop: remove definition and usage of macro SPRINTF
Existing definition of SPRINTF always resulted in sprintf() being used,
and sprintf() returning 'int' is already used throughout the library.
- ares_inet_ntop: reapply changes from previous c-ares version (III)
- Replace 'u_char' with 'unsigned char'.
- Replace 'u_int' with 'unsigned int'.
- use macros ERRNO and SET_ERRNO() for errno handling.
- ares_inet_ntop: reapply changes from previous c-ares version (II)
- Remove rcsid.
- Adjust header file inclusions.
- ares_inet_ntop used only on systems without a proper inet_ntop function.
- ares_inet_ntop: reapply changes from previous c-ares version (I)
- Replace tabs with spaces.
- Use ANSI C style for function declarations and definitions.
- Use sizeof with parentheses.
- ares_inet_ntop: fix off by one error triggering out of bounds write
ares_inet_ntop would trigger an out of bounds write when the representation
of the address required 15 characters, due to not taking in account null
termination character.
Full import of inet_ntop.c from bind-9.5.3rc1 to pull additional fixes.
- ares_nowarn: add conditional inclusion of assert.h header
- fix compiler warning: conversion may lose significant bits
- ares_inet_net_pton: fix non-rejection of some malformed literals
ares_inet_net_pton would return wrong values when excessively large,
and invalid, netmasks are used. Fixes are from bind-9.5.3rc1,
issue also described in the WLB-2008080064 advisory.
- setup_once: provide ISASCII macro
- configure: inet_net_pton function check adjustments
Define HAVE_INET_NET_PTON only when system's inet_net_pton function is IPv6
capable and is not affected by the WLB-2008080064 advisory.
HAVE_INET_NET_PTON_IPV6 is no longer defined nor used.
- ares_init: fix detection of semicolon comments in resolv.conf
File resolv.conf may either use a hash '#' or a semicolon ';' character as an
indication that the rest of the line is a comment. This fixes not recognizing
the semicolon as a valid comment indicator in resolv.conf.
- version: start working on 1.7.5
Version 1.7.4 (8 Dec 2010)
Daniel Stenberg (8 Dec 2010)

ares_parse_a_reply: fix CNAME response parsing
Reply to a CNAME query doesn't contain addresses, causing
ares_parse_a_reply() to bail out with ARES_ENODATA
Bug: http://groups.google.com/group/nodejs/browse_thread/thread/a1268c9ea5e9ad9b
Yang Tse (1 Dec 2010)
- fix compiler warning: conversion may lose significant bits
- atoi: remove atoi usage
- ares_init: fix compiler warning: conversion may lose significant bits
- configure: fix autoconf warning
- inet_pton: fix compiler warning
- configure: use autobuilds to temporarily verify strict aliasing warnings.
Temporarily, When cross-compiling with gcc 3.0 or later, enable strict aliasing
rules and warnings. Given that cross-compiled targets autobuilds do not run the
test-suite, there is no risk of running code that violates strict aliasing rules
- ares_getnameinfo: Partially revert commit 85520d66e0ac7ac73411bc25e98769a88b2f
Upon socket address family and length validation failure return ARES_ENOTIMP
in callback again, this is the error code documented in man page and used
mostly all over the library.
- ares_getnameinfo: Validate socket address family and length.
Validate socket address family and that the socket address length is appropriate
for the specified family. Failure is reported with ARES_EBADFAMILY in callback.
- ares_getnameinfo: fix two compiler warnings
- Added another VS10 version string
- Fix GCC 4 compiler warning 'dereferencing type-punned pointer might break strict-aliasing rules'.
- Revert commit 494274e653936335c255a47599970de3df21e7c4
- configure: fix autoconf 2.68 warning: no AC_LANG_SOURCE call detected in body
- Fix compiler warning: array subscript has type 'char'
- Fix GCC 4 compiler warning 'dereferencing type-punned pointer might break strict-aliasing rules'.
- Revert following commits:
07bc7ea79509bcc9ef6e09151e81766ed00d3392
3392a50ea3f8573ea4b7a9d82b9833dab60cb0e9
9912637d32c9987719a1ea12db591aee2941891c
The purpose of the whole patch was to silence a compiler warning triggered
with GCC 4 on file ares_process.c The specific compiler warning was
'dereferencing type-punned pointer might break strict-aliasing rules'.
A simpler patch will follow to equally silence the warning.
- ares_options: reorder header inclusions to make inclusion of
ares_private.h the last included one again.

- [Patrik Thunstrom brought this change]
adig: fix NAPTR parsing
I ran across a small "issue" in your adig example.
It is simply the last part of the NAPTR record, the replacement element,
which is not a string, as currently handled in adig, but a domain name.
- ares_save_options: assignments instead of memcpy
- init_by_options: don't copy an empty sortlist
If there aren't any sort items to copy, don't bother. Without this
little precaution it would do a malloc(0) which causes undefined
behaviors and is frowned upon by curl's memdebug-system.
Guenter Knauf (3 Oct 2010)
- Minor Watcom makefile tweaks.
Daniel Stenberg (30 Sep 2010)
- [Mike Crowe brought this change]
Fix lookup with HOSTALIASES set.
ares__read_line returns ARES_EOF when it reaches the end of the
file. This will happen every time when reading to the end of the
HOSTALIASES file. Unfortunately single_domain treats this error as
being fatal.

Yang Tse (30 Dec 2009)
- VMS specific preprocessor symbol checking adjustments
- Mention last changes
- - Fix configure_socket() to use ares_socket_t instead of int data type.
- - Where run-time error checks enabling compiler option /GZ was used it is now

- Compiler option /GX is now replaced with equivalent /EHsc for all versions.
- - Ingmar Runge noticed that Windows config-win32.h configuration file

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

- changed u_int16_t to unsigned short because it is the only place within ares and curl where such a type would be used;
also it broke many autobuilds. We should probably introduce an ares_port_t if we want to use a type here.
Gisle Vanem (5 Sep 2009)
- Replace 'uint16_t' with 'u_int16_t' since the latter is used in ares.h.
- Added 'ares_parse_srv_reply.obj'. Added definition of 'u_int16_t'. This is I don't like; we should not depend on such non-universal types in a public header. But this is just a quick fix.
Daniel Stenberg (4 Sep 2009)

ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
better allow the callback to know what's happening.
- - Joshua Kwan fixed the init routine to fill in the defaults for stuff that
fails to get inited by other means. This fixes a case of when the c-ares
init fails when internet access is fone.
Gunter Knauf (16 Jul 2009)
- test if adding ../lib to includes can fix the current break ...
- renamed generated config.h to ares_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h.
Yang Tse (21 Jun 2009)
- Refactor how libraries are checked for connect() function, follow-up.
- Refactor how libraries are checked for connect() function,
and check for connect() as it is done for other functions.
Gisle Vanem (20 Jun 2009)
- Remove unneeded defines.
- Use select_s() and not select().
Yang Tse (19 Jun 2009)

now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
config file preprocessor definitions.
- add CloseSocket camel case function check
- check for socket() and closesocket() as it is done for other functions
- Remove HAVE_CONFIG_H definition from here,
CFLAGS from common.dj already defines it.
- initial step towards decoupling c-ares from libcurl for DOS
- don't ignore these subdirs, they must be removed first
- Remove DEBUGBUILD symbol definition, is not required for programs using the library.
- DEBUGBUILD symbol definition for debug builds
- ignore some subdirs
- fix comment
- Try to make more clear that --enable-curldebug has nothing to do with --enable-debug for this library.
- Revert last change, it is inappropriate.
Gisle Vanem (12 Jun 2009)
- Replace CURLDEBUG with DEBUGBUILD.
Yang Tse (11 Jun 2009)
- when running automake copy missing files instead of symlinking them
- Adjusted to take in account that...
With the curl memory tracking feature decoupled from the debug build feature,
CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:
CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)
DEBUGBUILD used for debug enabled specific code (--enable-debug)
- c-ares' --enable-debug --enable-curldebug decoupling follow-up
- mention last changes
- Remove buildconf.bat from release and daily snapshot archives.
buildconf.bat is only for CVS tree builds.
- Ensure that buildconf.bat does nothing unless it is used with a CVS checkout.
- CVS-INFO file only present in CVS tree, never in release nor daily snapshot
archives. Used as a sentinel file in buildconf.bat to differentiate CVS builds.
Gisle Vanem (8 Jun 2009)
- Update comment about "ML". Removed "-D_USE_32BIT_TIME_T" (not a requirement).
Yang Tse (8 Jun 2009)
- just comment it out
- For debugging purposes...
Disable the '-export-symbols-regex' to discard this as the origin
of link failures related with shared libraries and non-GNU linkers.
- c-ares Makefile.am back to using $(top_builddir) for *_LDADD
- c-ares' -no-undefined and --enable-curldebug adjustments
- Use relative path to built c-ares tree libtool library
- John E. Malmberg noticed that the configure script was failing to detect the
timeval struct on VMS when building with _XOPEN_SOURCE_EXTENDED undefined due
to definition taking place in socket.h instead of time.h
- Fix compiler warning: out of bound access
- fix compilation on AIX
- c-ares' --enable-curldebug adjustments
- Remove temporarily introduced memory leak.
- Temporarily introduce a memory leak to verify curl debug memory tracking works.
- Allow curl debug memory tracking when building a shared library on
systems which support external, undefined, symbols in shared libraries.
Daniel Stenberg (26 May 2009)
- language fix
Yang Tse (26 May 2009)
- Make ares_init(), ares_dup() and ares_init_options() return ARES_ENOTINITIALIZED
if library initialization has not been performed calling ares_library_init().

RtlGenRandom, has been located or not. This function is only available on
WinXP and later. When unavailable c-ares uses portable rand() function.
- - Provide in external interface preprocessor symbol definitions for
CARES_HAVE_ARES_LIBRARY_INIT and CARES_HAVE_ARES_LIBRARY_CLEANUP
to ease the use of new capabilities.

NEED_MALLOC_H and NEED_MEMORY_H respectively.
- ignore
Gisle Vanem (18 Apr 2009)
- Added '-DHAVE_LIMITS_H'.
Yang Tse (17 Apr 2009)

Phil Blundell (3 Feb 2009)
- * February 3 2009 (Phil Blundell)
- If the server returns garbage or nothing at all in response to an AAAA query,
go on and ask for A records anyway.
Daniel Stenberg (31 Jan 2009)
- - ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving
either AF_INET6 or AF_INET. It works by accepting any of the looksups in the
hosts file, and it resolves the AAAA field with a fallback to A.
Gisle Vanem (18 Jan 2009)
- fopen() returns error in 'errno' even on Windows.
So don't use ERRNO (GetLastError()). Trimmed trailing
blanks.
- Constified some arguments in local functions.
Daniel Stenberg (14 Jan 2009)
- - ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it
now declares the private struct ares_in6_addr for all systems instead of
relying on one possibly not present in the system.
Phil Blundell (13 Jan 2009)
- - ares__send_query() now varies the retry timeout pseudo-randomly to avoid
packet storms when several queries were started at the same time.
Daniel Stenberg (11 Jan 2009)
- - Phil Blundell added the internal function ares__expand_name_for_response()
that is now used by the ares_parse_*_reply() functions instead of the
ares_expand_name() simply to easier return ARES_EBADRESP for the cases where
the name expansion fails as in responses that really isn't expected.
Gunter Knauf (30 Dec 2008)
- added HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID to ares Makefile.netware and sync'd with other Makefile.netware.
Daniel Stenberg (9 Dec 2008)
- use the new URL
- start over on the 1.6.1 release...
Version 1.6.0 (9 Dec 2008)

- add space
Gisle Vanem (9 Dec 2008)
- Fix for Win32 targets using Watt-32.
Dan Fandrich (9 Dec 2008)
- C89 compilers (like Minix' ACK) only need to handle 31 functions arguments
so split a long sprintf into two calls to get below that number.
Gisle Vanem (8 Dec 2008)
- Added needed defines for Watt-32 on Windows.
- Undefine 'optarg', 'optind' and 'opterr' when using Watt-32
(to get correct linkage on Windows).
- ares_writev() shall not be exported when using Watt-32 (has writev).
Added _USE_32BIT_TIME_T to avoid runtime warning. Applies to
VC-2008+ only.
- Removed unneeded defines HAVE_SIGNAL_H, HAVE_SIG_ATOMIC_T,
RETSIGTYPE and HAVE_PROCESS_H.
Daniel Stenberg (4 Dec 2008)
- the initial version of the ares_set_socket_callback man page
- Gregor Jasny provided the patch that introduces ares_set_socket_callback(),
and I edited it to also get duped by ares_dup().
Dan Fandrich (4 Dec 2008)
- Bring the sys/include.h include test in line with curl's.
Daniel Stenberg (3 Dec 2008)
- Let's not call ares_save_options() deprecated just yet
- Introduce ares_dup(3) and new thoughts about API/ABI and how to move forwards.
Also discussed on the ml.
Dan Fandrich (2 Dec 2008)
- Make sure sys/socket.h is included before netinet/in.h (required by
OpenWatcom C, and condoned by SUS)
Daniel Stenberg (1 Dec 2008)
- minor indent fix
- Convert the public config struct to the same binary size/construct as in the
latest releases to remain ABI compatible.
Gisle Vanem (29 Nov 2008)

buffer to shrink instead of expand if a reply contained 8 or more records.
- Brad Spencer provided changes to allow buildconf to work on OS X.
- In preparation for the upcomming IPv6 nameservers patch, the internal
ares_addr union is now changed into an internal struct which also holds
the address family.
Dan Fandrich (20 Nov 2008)
- Make checking for struct ifreq a prerequisite for setting
HAVE_IOCTL_SIOCGIFADDR since it's needed to use SIOCGIFADDR and Watcom C
doesn't currently define it.
Daniel Stenberg (20 Nov 2008)
- use unsigned short better intead of mixing with ints to prevent compiler
warnings
- please the picky compilers by staying with short as the data we get is short
only
- - Brad Spencer brought the new function ares_gethostbyname_file() which simply
resolves a host name from the given file, using the regular hosts syntax.
Yang Tse (19 Nov 2008)
- user provided PATH_SEPARATOR always overrides auto-detected one
- attempting to keep lines below 80 chars
- provide a common PATH_SEPARATOR check method which is required by
upcomming work to support the broadest range of Autoconf versions
- check for gethostbyaddr and gethostbyname as it is done for other functions
- Make configure script check if ioctl with the SIOCGIFADDR command can be
used, and define HAVE_IOCTL_SIOCGIFADDR if appropriate.

checks for inet_ntoa_r() inet_ntop() and inet_pton()
- #include <string.h> in the getaddrinfo() runtime check for the memset() prototype
- fix symbol definition check for fcntl.h inclusion
- Refactor configure script detection of functions used to set sockets into
non-blocking mode, and decouple function detection from function capability.
Daniel Stenberg (1 Nov 2008)
- Added a TODO file to list things we want changed, added or fixed.
- - Carlo Contavalli added support for the glibc "rotate" option, as documented
in man resolv.conf:
causes round robin selection of nameservers from among those listed. This
has the effect of spreading the query load among all listed servers, rather
than having all clients try the first listed server first every time.
You can enable it with ARES_OPT_ROTATE
Yang Tse (1 Nov 2008)
- Adjust WIN32 freeaddrinfo, getaddrinfo and getnameinfo availability
- WIN32 availability of freeaddrinfo, getaddrinfo and getnameinfo functions is quite
convoluted, compiler dependant and in some cases even build target dependat.
- check for freeaddrinfo() at configuration phase
- update aclocal file serial number
- remove verification of the freeability of the addrinfo struct pointer members
- fix comment
- make CHECK_FUNC_GETADDRINFO_UNFREEABLE_AI_ADDR
and CHECK_FUNC_GETADDRINFO_UNFREEABLE_AI_CANONNAME
internal to CHECK_FUNC_GETADDRINFO
- fix leftover
- Initial attempt to detect at configuration time if the getaddrinfo()
function returns an addrinfo with an unfreeable ai_canonname member ptr.
- Initial attempt to detect at configuration time if the getaddrinfo()
function returns an addrinfo with an unfreeable ai_addr member ptr.
- icc adjustments:
Select ANSI C89 dialect plus GNU extensions, again.
- some more temporary magic for the icc seg-fault issue
- icc permanent adjustment:
Select precise floating-point model, otherwise doubles are less than 64-bit wide
icc test adjustment:
Select c89 dialect
- icc adjustments:
Enable more icc warnings.
Optimization disabling options used only for icc 9.1
- #include <stdlib.h> for exit() prototype
- some more temporary magic for the icc seg-fault issue
- remove from configure.ac temporary magic for the icc seg-fault issue
- some more temporary magic for the icc seg-fault issue
- Charles Hardin patch:
- handles the EINPROGRESS for UDP connects
- uses closesocket instead of close on some paths that were noticed
- some more temporary magic for the icc seg-fault issue
- messages initially intended only for debug purposes, now become permanent
since these are extremely useful when compiler rejects a set of options.
- fix compiler warning
- fix missing double-quotes
Daniel Stenberg (17 Oct 2008)
- Charles Hardin made adig support a regular numerical dotted IP address for the
-s option as well.
Yang Tse (16 Oct 2008)
- some more temporary magic for the icc seg-fault issue
- Ensure that shell variable contents which have active meaning
to the shell echo command are not interpreted when trying to
remove extra whitespace from shell variable content.
- Adjust Watcom C warnings:
Disable warnings on structure members padding.
- With this change Solaris target builds will now be done with _REENTRANT defined.
- Adjust Tiny C basic options:
Remove -b from debug-enabled configuration, as Tiny C might have
been built without the memory and bounds checker support.
- Adjust GCC warnings:
Better disable following warnings when cross-compiling with a gcc older
than 3.0, to avoid warnings from third party system headers:
-Wmissing-declarations
-Wmissing-prototypes
-Wunused
-Wshadow
- fix syntax error
- Initial attempt to detect Watcom C compiler
- make naming scheme more consistent across whole file
- Adjust GCC warnings:
Disable following warnings when cross-compiling with a gcc older
than 3.0, to avoid warnings from third party system headers:
-Wmissing-prototypes
-Wunused
-Wshadow
- Adjust GCC --enable-warnings:
Do not enable -pedantic when cross-compiling with a gcc older
than 3.0, to avoid warnings from third party system headers.
- adjust SGI MIPSpro C detection
- LCC compiler adjustments:
Highest warning level is double -A, next is single -A.
Due to the big number of warnings these trigger on third
party header files it is impratical for us to use any of
them here. If you want them simply define it in CPPFLAGS.
- remove extra space
- split SGI compiler check. One for MIPS C and another for MIPSpro C
- LCC compiler adjustments:
Warning level reduced from double -A to single -A
- Initial attempt to detect Tiny C compiler
- Initial attempt to detect LCC compiler
- 1) fix bug in CONVERT_INCLUDE_TO_ISYSTEM
2) Disable SGI remark: controlling expression is constant
- simplify SGI C compiler check
- HP C adjustments:
Due to the HP-UX socklen_t issue it is insane to use the +w1 warning level.
It generates more than 1100 warnings on socklen_t related statements.
Until the issue is somehow fixed we will just use the +w2 warning level.
- Add debug tracing for COMPILER_WORKS_IFELSE
- configure will also warn on 'strict compiler warning' rejected options
- convert rejected compiler options messages into a warnings
- remove extra whitespace from string in SGI C check
- oops
- Initial attempt to detect SGI C compiler

- refactoring of COMPILER_BASIC_OPTS
- Initial attempt to detect SUN C compiler
- Initial attempt to detect HP C compiler
- fix compiler warning: 'dot_4' may be used uninitialized in this function
- adjust ICC_windows settings
- fix VAR_STRIP
- Sync up with reality
- Initial attempt to support configure's --(dis|en)able-optimize
option to specify dis(activation) of compiler optimizations.
If option is specified, it will be honored independant of the
--(dis|en)able-debug option.
- fix comment
- Initial attempt to support configure's --(dis|en)able-warnings
option to specify dis(activation) of picky compiler warnings.
If option is specified, it will be honored independant of the
--(dis|en)able-debug option.
If option is not specified, it will follow --(dis|en)able-debug
setting, whose default is disabled if not specified.
- fix compiler warning: dereferencing type-punned pointer will break strict-aliasing rules
- now compiler warnings are activated for all gcc builds, not only debug ones.
- Use CFLAGS for icc linker options instead of LDFLAGS,
otherwise gethostbyname() is not detected.
- use ac_cv_compiler and ac_cv_compiler_num to keep compiler ID and version number
- Temporary icc adjustment:
Disable floating point optimizations
- HAVE_INET_PTON will only be defined when an IPv6 capable working
inet_pton function is available.
- HAVE_INET_NTOP will only be defined when an IPv6 capable working
inet_ntop function is available.
- ntoa() and inet_ntoa_r() no longer used
- icc adjustments for icc 9.0 and prior versions:
Disable remark #279: controlling expression is constant
Remark triggered mostly on va_arg() and FD_ZERO() macros.
- attempt to make work the gethostname function
check for winsock build target configurations
Gisle Vanem (21 Sep 2008)
- Added HAVE_NETDB_H, HAVE_ARPA_INET_H, HAVE_STRCASECMP
and HAVE_STRNCASECMP.
Yang Tse (19 Sep 2008)
- icc adjustments:
Disable remark #981: operands are evaluated in unspecified order
Function calls which are triggering this remark, today, do not depend
on the order of evaluation of its arguments.
Disable remark #1469: "cc" clobber ignored
Remark triggered on htons() and ntohs() due to glibc header files.
- icc adjustments
- fix netdb.h prerequisite inclusion
- improve detection of getservbyport_r()
- On Linux Intel's icc uses gcc's header files, so
we select ANSI C89 dialect plus GNU extensions.
- improve detection of gethostname()
- NetWare builds include "nameser.h" from the c-ares subdir
- include <strings.h>
- Sync up with reality
- adjust inclusion of "nameser.h"
- reorder some lines in file
- code cleanup
- NetWare seems to have writev()
- rearrange to allow internal/private use of ares_writev to any system
that lacks the writev function.
- NetWare CLIB target has stricmp() and strnicmp()
- include header file only when available
- rearrange to allow internal/private use of ares_strcasecmp to any system that
lacks the strcasecmp function.
- improve detection of:
strcasecmp()
strcmpi()
stricmp()
strncasecmp()
strncmpi()
strnicmp()
- *** empty log message ***
Gisle Vanem (12 Sep 2008)
- djgpp does have strdup().
Yang Tse (12 Sep 2008)
- change CRLF into LF line endings
- strdup() clone for systems/configurations which lack it
- move inclusion of ares_private.h last
- icc adjustments
- icc adjustments
- Select strict ANSI C89 conformance for icc
- remove unnecessary typecasting of malloc()
- remove unnecessary typecasting of realloc()
Daniel Stenberg (29 Aug 2008)

Version 1.5.3 (29 Aug 2008)
Daniel Stenberg (29 Aug 2008)
- Version 1.5.3
- added the three people from RELEASE-NOTES and sorted the list alphabetically
Yang Tse (27 Aug 2008)
- Don't abort configuration if recvfrom() is not available.
- Functionality only possible if recvfrom() is available.
- George Neill's fix acountry sample application compilation failure.
- Brad House's validation that DNS response address matches the request address
- fix the output name
- Get rid of ENABLE_64BIT symbol definition and usage.
Improve HAVE_LONGLONG symbol description.
- Export 'ares_process_fd' too.
Gisle Vanem (16 Aug 2008)
- Ops, remove 'use_vc'.
- Support Watt-32 under Win32.
Yang Tse (10 Aug 2008)
- Fix: Remove now this SIZEOF_CURL_OFF_T symbol definition.
This should have been done with the initial 64-bit curl_off_t patch.
- Improve CURL_CHECK_DEF
- Fix IBM C and DEC/Compaq C compiler detection
- Initial support of curlbuild.h and curlrules.h which allows
to have a curl_off_t data type no longer gated to off_t.
- The minimum autoconf version required for this file is 2.50
Avoid dot notation in aclocal serial file number, use a single number now.
Daniel Stenberg (4 Aug 2008)
- - Fix by Tofu Linden:
The symptom:
* Users (usually, but not always) on 2-Wire routers and the Comcast service
and a wired connection to their router would find that the second and
subsequent DNS lookups from fresh processes using c-ares to resolve the same
address would cause the process to never see a reply (it keeps polling for
around 1m15s before giving up).
The repro:
* On such a machine (and yeah, it took us a lot of QA to find the systems
that reproduce such a specific problem!), do 'ahost www.secondlife.com',
then do it again. The first process's lookup will work, subsequent lookups
will time-out and fail.
The cause:
* init_id_key() was calling randomize_key() *before* it initialized
key->state, meaning that the randomness generated by randomize_key() is
immediately overwritten with deterministic values. (/dev/urandom was also
being read incorrectly in the c-ares version we were using, but this was
fixed in a later version.)
* This makes the stream of generated query-IDs from any new c-ares process
be an identical and predictable sequence of IDs.
* This makes the 2-Wire's default built-in DNS server detect these queries
as probable-duplicates and (erroneously) not respond at all.
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. But,
autoconf 2.62 version of AC_AIX defines _ALL_SOURCE along with other four
preprocessor symbols no matter if the system is AIX or not. To keep the
traditional behaviour, as well as an uniform one, across autoconf versions
AC_AIX is replaced with our own internal macro.
- Adjust DEC/Compaq C compiler settings.
- Another AC_TRY_LINK conversion to AC_LINK_IFELSE.
Proper definition of HAVE_function if function is found deeper.
- Sync up with reality
- Rename reentrant.m4 to avoid filename clash.
- Add file version serial number that might be used by 'aclocal' and others.
Keep the '#' character as the first one on the line.
- Update copyright year.
- Sync comment with reality.
- Reinstate the 'aclocal -I m4' in buildconf and 'ACLOCAL_AMFLAGS = -I m4' way of
including our local m4/reentrant.m4 file. This even takes care of including the
file in the distribution tarball.
- Add quoting for the AC_DEFINE arguments.
- Also remove the whitespace.
- Also remove the extra quoting.
- Replace some '@%:@' quadigraphs by its actual representation '#'.
This quadigraph used before a C preprocessor 'define' directive could
be fooling M4, when processing this file, and make it think that the
line contains a pure M4 'define' macro.
- Tests done using 'aclocal -I m4' in buildconf and 'ACLOCAL_AMFLAGS = -I m4
in top Makefile.am triggered a problem that prevented aclocal from running
successfully on SunOS 5.10 with GNU m4 1.4.5 and GNU Autoconf 2.61
A tarball which reproduces mentioned problem is the one dated July-28-2008
http://cool.haxx.se/curl-daily/curl-7.19.0-20080728.tar.gz
We actually don't need all the bells and whistles that the above mechanism
provides. We only need to include our m4/reentrant.m4 file in acinclude.m4
so here we go with this simpler mechanism.
- for debugging purposes show ACLOCAL_FLAGS
- These lines were unintentionally removed in previous commit
- Partially undo change that prevented SED, GREP, EGREP and AR from being changed by libtool or autoconf.
- Assert that SED and GREP are set
- Require autoconf 2.57 or newer
- When calling aclocal, user defined ACLOCAL_FLAGS will now precede ours.
- move ACLOCAL_AMFLAGS after AUTOMAKE_OPTIONS
- setup.h handles definition of _REENTRANT based on NEED_REENTRANT
definition which might be defined in config.h or config-*.h files
- Remove explicit inclusion of our m4 files first. It was interesting as a test,
but it breaks aclocal execution on some systems, with the following error:
Can't locate object method "rel2abs" via package "File::Spec" at /usr/local/bin/aclocal line 256.
- Another step towards detecting if _REENTRANT is already defined or actually
needed, and being able to define it if appropriate for further configure tests
as well as for the generated config file.
- Explicitly include our m4 files first. This might minimize the impact
that other package's underquoted m4 function definitions have on ours.
- Add a 3 argument check for getprotobyname_r
- move reentrant.m4 to the m4 subdirectory to avoid infinite loop inclusion problem
- add checks for strtok_r and getprotobyname_r
- 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.
- reorder argument number detection for getservbyport_r to
actually verify if the test is properly working
- Make sure that configure process tests are done with the same _REENTRANT
setting as the one actually used when finally building the library.
- 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
- use prototypes to improve getservbyport_r detection
- Adjust recvfrom's sixth arg data type definition for NetWare (LIBC)
- Use the sreadfrom() wrapper to replace recvfrom() in our code.
- 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.
- Adjust DEC/Compaq C compiler settings
- 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
- Adjust DEC/Compaq C compiler settings
- 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.
- 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.
- Initial DEC/Compaq C compiler detection and flags
- Improved configure detection of number of arguments for getservbyport_r
- 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.
- fix compiler warning
- since Jun 30 2008 MAXHOSTNAMELEN define is no longer used
- fix c-ares version reported in generated libcares.pc file when building
from CVS tree.
- egrep and ar are also mandatory
Daniel Stenberg (3 Jul 2008)
- just to clarify that c-ares actually have some ipv6 support
- ares_gethostbyname() fallback from AAA to A records with CNAME present
- - 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.
Yang Tse (2 Jul 2008)
- The configure process will now halt when sed or grep are unavailable
- fallback to gettimeofday when monotonic clock is unavailable at run-time
- IBM C/C++ compiler predefined macro check
- set earlier in configure process IBM compilers optimization flags
- make check message wording more precise
Daniel Stenberg (30 Jun 2008)
- - As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is
not posix or anything and thus c-ares failed to build on hurd (and possibly
elsewhere). The define was also somewhat artificially used in the windows
port. Now, I instead rewrote the use of gethostbyname to enlarge the host
name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN
define. I thus also removed the defien from the namser.h file where it was
once added for the windows build.
I also fixed init_by_defaults() function to not leak memory in case if
error.
Yang Tse (29 Jun 2008)
- fix C style comment
- 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.
- 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.
Gunter Knauf (11 Jun 2008)
- enable additional CFLAGS from commandline.
Yang Tse (9 Jun 2008)
- fix pkg-config reporting of private libraries needed for static linking
- MSVC does build Windows native targets
- Brad House fixed a missing header file inclusion in adig sample program
Daniel Stenberg (29 May 2008)
- start working on 1.5.3
Version 1.5.2 (29 May 2008)
Daniel Stenberg (29 May 2008)
- 1.5.2
Yang Tse (26 May 2008)
- fix compiler warning: unreferenced formal parameter
Daniel Stenberg (23 May 2008)
- list all local sources the (demo) tools need, add a few missing scripts to
the dist tarball and remove a two duplicate file names from EXTRA_DIST
(most of it pointed out by Yang Tse)
- this is not used (anymore)
- make sure the configure.ac file with the correct version number is shipped
in the tarball
Yang Tse (22 May 2008)
- MSVC6+ clean-up targets must also remove acountry.exe
- sync with reality
- fix: [action-if-found] part of AC_CHECK_TYPE macro cannot be quoted when empty
- fix: remove need and definition of HAVE_SOCKLEN_T symbol
- fix: socklen_t definition comment
- update several macros using AC_TRY_LINK with AC_LINK_IFELSE
- fix underquoting of AC_LANG_PROGRAM arguments
- if'def out private function ares__tvdiff(), it is not in use yet.
- update several macros using AC_TRY_LINK with AC_LINK_IFELSE
- fix socklen_t equivalent detection when cross compiling Windows target
- 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'.
- 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.
- minor change for wince-cegcc and wince-mingw32ce support
- millisecond resolution support followup
Gisle Vanem (15 May 2008)
- Replaced "-DHAVE_FIONBIO" with "-DHAVE_IOCTLSOCKET".
Added "-DHAVE_GETTIMEOFDAY". Trimmed lines.
Yang Tse (15 May 2008)
- sync with reality
- remove compilation time generated files
- use same time source for timeout initialization and processing
- 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.
- skip checks for Windows specific header files
when build target is not a native Windows one
- WinCE cross compilation adjustments:
HAVE_WINSOCK2_H shall not be defined.
HAVE_WS2TCPIP_H shall not be defined.
Daniel Stenberg (13 May 2008)
- - Introducing millisecond resolution support for the timeout option. See
ares_init_options()'s ARES_OPT_TIMEOUTMS.
Yang Tse (13 May 2008)
- also ignore this
- also ignore this
- ignore this compilation time generated files
- don't keep in CVS this compilation time generated file
- add MSVC6 project for acountry sample program
- update MSVC6 projects to use the multithreaded DLL runtime library
- add MSVC6 project for acountry sample program
- skip libtool C++ preprocessor compiler and linker checks
- ignore libcares.pc
- 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.
- fix syntax error: missing semicolon
- Add library checking for clock_gettime() support
- Use monotonic time source if available.
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
- include strings.h (if available) for the strcasecmp() proto
- check for strings.h in configure and use it for the strcasecmp() proto
- 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
- Eino Tuominen improved the code when a file is used to seed the randomizer
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.
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.
- 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.
- fixed linker def file for tools when compiled with gcc/nlmconv.
- added some files which were missing in release tarballs.
- updated copyright for new year.
Gisle Vanem (2 Jan 2008)
- Added '-d' option for Watt-32 debugging.
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).
Daniel Stenberg (11 Dec 2007)
- build acountry too
Gisle Vanem (11 Dec 2007)
- Added acountry.c.
- Added build of acountry.nlm.
- Added build of acountry.exe.
- Build acountry.exe. Added 'socklen_t' define.
- Another sample application that returns country-code and
name from an IPv4-address or host-name. Using the service of
countries.nerd.dk.
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
- when building
- build ahost and adig by default but don't install them
Gisle Vanem (10 Dec 2007)
- Fix for targets that do have 'struct in6_addr', but which doesn't
define 's6_addr' as a macro.
Yang Tse (3 Dec 2007)
- Fix three issues previous cleanup introduces.
Daniel Stenberg (3 Dec 2007)
- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat
- 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.
- the gethostbyname fix applied here as well
- 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
- Remove the check for libdl since that isn't actually used and it causes
warnings. Pointed out by Robin Cornelius.
- pkgconfig fix by Andreas Schuldei
- spellfix
- and we start on 1.5.2!
Version 1.5.1 (21 Nov 2007)
Daniel Stenberg (21 Nov 2007)
- change
- oops
- start working on 1.5.1 now
Version 1.5.0 (21 Nov 2007)
Daniel Stenberg (21 Nov 2007)
- this is what 1.5.0 is
- fill in missing copyrights
Gunter Knauf (18 Nov 2007)
- removed now obsolete defines;
updated external library versions to latest.
Steinar H. Gunderson (16 Nov 2007)
- Fix a double free.
Yang Tse (15 Nov 2007)
- Needed now that in6_addr is referenced in ares.h
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.
- Return TTL data from ares_parse_{a,aaaa}_reply, if the user is so inclined. Patch from the Google tree.
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.
- The only libraries actually needed for sample programs adig and
ahost are ws2_32.lib and advapi32.lib
- MSVC versions prior to VS2005 do not complain about portable C functions
- 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.
Gunter Knauf (22 Oct 2007)
- removed dependency on gettimeofday() since we use only 1 sec resolution here.
Yang Tse (20 Oct 2007)
- Fix compiler warning: conversion from "int" to "unsigned short" may lose significant bits
- Fix message shown when detecting icc version
- Avoid shadowing a global declaration
- Renamed a variable to avoid shadowing a global declaration
- Renamed internal function to avoid a variable shadowing it
- Fix compiler warning: feupdateenv is not implemented and will always fail.
Specifically for linux x86-64 with Intel's icc.
- Sync PLATFORM_AIX_V3 detection and CURL_CC_DEBUG_OPTS()
icc warning level with libcurl's
- Fix compiler warning: conversion from "int" to "unsigned char"
may lose significant bits
- actually sync with lib/setup_once.h
- sync with lib/setup_once.h
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.
Dan Fandrich (15 Oct 2007)
- Mention first version with CURLOPT_COPYPOSTFIELDS.
Don't confuse NUL with NULL.
Gisle Vanem (8 Oct 2007)
- Added needed 'HAVE_*' defines.
- 'FD_CLOXEC' is meaningless on MSDOS/Watt-32.
Steinar H. Gunderson (4 Oct 2007)
- Removed a piece of redundant code (process_answer already takes care of it).
- Another timeout fix in ares_getnameinfo().
- Send the timeout count in ares_getnameinfo().
- Moved the NULL check for channel upwards in ares_destroy().
- Clarified the comment over ares_cancel.
Yang Tse (2 Oct 2007)
- Avoid a segfault when generating a DNS "Transaction ID" in internal
function init_id_key() under low memory conditions.
- Add ares_llist.c and ares_llist.h to MSCV project file.
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.
Yang Tse (2 Oct 2007)
- Avoid inline C99ism, and move c-ares routines for managing doubly-linked lists.
Daniel Stenberg (1 Oct 2007)
- ares_strerror() segfaulted if the input error number was out of the currently
supported range.
- Prevent ares_strerror() from segfaulting if an invalid error code is passed
in as argument!
Yang Tse (30 Sep 2007)
- Fix compiler warning
- check availability of <netinet/tcp.h>
- improve portability, defining MAXDNAME and MAXCDNAME
Steinar H. Gunderson (30 Sep 2007)
- Fix a memory leak that I recently inadvertedly introduced.
- Use ISDIGIT instead of isdigit; fixes a gcc warning.
- Port the TCP socket fix made in ares_fds() to ares_getsock() as well.
- 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.
Gisle Vanem (29 Sep 2007)
- We should standarise on C comments.
- Fix compiler warning in setsockopt().
Steinar H. Gunderson (29 Sep 2007)
- TCP queries can time out too, not just UDP queries. (Patch from the Google tree.)
- 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.)
- 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.)
- Reject names that are longer than 255 characters, to avoid problems with strict or buggy DNS server implementations. (Patch from the Google tree)
- In ares_mkquery, make sure we set buflen and buf to reasonable values if there's an error. (Patch from the Google tree)
- Be stricter about what's a valid IP address in fake_hostent. (Patch from the Google tree.)
- Handle the root of the DNS tree correctly in ares_expand_name.
Daniel Stenberg (28 Sep 2007)
- today's modifications by Steinar and me
- 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)
Steinar H. Gunderson (28 Sep 2007)
- Unrevert previous 'missing' hunks. They were missing since the patch is still in for review :-)
- Yet more missing hunks... Nggh.
- 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.
- Forgot to include a few hunks from ares_process.c earlier. Fixing now.
- Support a few more socket options, and refactor the option setting a bit. (Patch from the Google tree.)
- 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.)
- 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.
- Don't skip a server if it's the only one. (Bugfix from the Google tree.)
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
- eek, fix the conditions to return on either problem instead of requiring
both to occur
- Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in
several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that
if it fails and the socket is closed the following code doesn't try to use
the file descriptor.
- Steinar H. Gunderson modified c-ares to now also do to DNS retries even when
TCP is used since there are several edge cases where it still makes sense.
- Brad House provided a fix for ares_save_options(): Apparently I overlooked
something with the ares_save_options() where it would try to do a malloc(0)
when no options of that type needed to be saved. On most platforms, this was
fine because malloc(0) doesn't actually return NULL, but on AIX it does, so
ares_save_options would return ARES_ENOMEM.
- added initial pkg-config file (attempt)
Gunter Knauf (20 Jul 2007)
- added curl include for debug builds.
Daniel Stenberg (14 Jul 2007)
- added another SEE ALSO
- Brad House's fix to hish a win32 compiler warning
- added Vlad's entire description of his valgrind fix
- Vlad Dinulescu fixed two outstanding valgrind reports
Gunter Knauf (8 Jul 2007)
- added better CodeWarrior detection.
- removed some obsolete include paths and defines.
- add test for gettimeofday() so that HAVE_GETTIMEOFDAY gets defined.
- 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.
- added check for sys/param.h.
- trial to catch problem with Daniels cross-mingw ares builds.
- added NetWare CLIB-own header to solve gcc warnings.
- few minor changes to make ares compile for NetWare CLIB architecture.
- changed to build for CLIB / LIBC.
- sync'd with lib makefile changes: use var for awk; fixed RECV* / SEND* defines; debug var can be overwritten; added better compiler path handling.
Daniel Stenberg (8 Jun 2007)
- start working on 1.4.1
Version 1.4.0 (8 Jun 2007)
Daniel Stenberg (8 Jun 2007)
- 1.4.0 preps
- the revert
- Revered Ashish Sharma's multiple entries patch, as it caused memory madness
- minor edit since getting an ID seems pointless when failure happens
- fix the bad bad bad mess this caused on name resolves returning more than
one name... Reported by James Bursa
- Brad Spencer found and fixed three flaws in the code, found with the new
gcc 4.2.0 warning: -Waddress
- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
He also made recent Microsoft compilers use _strdup() instead of strdup().
- Ashish Sharma provided a patch for supporting multiple entries in the
/etc/hosts file. Patch edited for coding style and functionality by me
(Daniel).
