Changelog for the c-ares project
|
||
|
|
||
|
Version 1.7.1 (Mar 23, 2010)
|
||
|
|
||
|
* March 23, 2010 (Daniel Stenberg)
|
||
|
- We switched from CVS to git. See http://github.com/bagder/c-ares
|
||
|
|
||
|
* March 5, 2010 (Daniel Stenberg)
|
||
|
- Daniel Johnson provided fixes for building with the clang compiler.
|
||
|
|
||
|
* March 5, 2010 (Yang Tse)
|
||
|
- Added IPv6 name servers support. Implementation has been based on code,
|
||
|
comments and feedback provided November and December of 2008 by Daniel
|
||
|
Stenberg, Gregor Jasny, Phil Blundell and myself, December 2009 by Cedric
|
||
|
Bail, and February 2010 by Jakub Hrozek on the c-ares mailing list. On
|
||
|
March I reviewed all that, selected the best of each, and adjusted or
|
||
|
extended parts of it to make the best fit.
|
||
|
|
||
|
The external and visible result of all this is that two new functions are
|
||
|
added to the external API, ares_get_servers() and ares_set_servers(), which
|
||
|
becomes now the preferred way of getting and setting name servers for any
|
||
|
ares channel as these support both IPv4 and IPv6 name servers.
|
||
|
|
||
|
In order to not break ABI compatibility, ares_init_options() with option
|
||
|
mask ARES_OPT_SERVERS and ares_save_options() may still be used in code
|
||
|
which is intended to run on IPv4-only stacks. But remember that these
|
||
|
functions do not support IPv6 name servers. This implies that if the user
|
||
|
is capable of defining or providing an IPv6 name server, and the app is
|
||
|
using ares_init_options() or ares_save_options() at some point to handle
|
||
|
the name servers, the app will likely loose IPv6 name servers.
|
||
|
|
||
|
* January 28, 2010 (Daniel Stenberg)
|
||
|
- Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't
|
||
|
check for broken connections like ares_process() did. Based on that, I
|
||
|
merged the two functions into a single generic one with two front-ends.
|
||
|
|
||
|
* December 29, 2009 (Yang Tse)
|
||
|
- Laszlo Tamas Szabo adjusted Makefile.msvc compiler options so that where
|
||
|
run-time error checks enabling compiler option /GZ was used it is replaced
|
||
|
with equivalent /RTCsu for Visual Studio 2003 and newer versions. Option
|
||
|
/GX is replaced with equivalent /EHsc for all versions. Also fixed socket
|
||
|
data type for internal configure_socket function.
|
||
|
|
||
|
* December 21, 2009 (Yang Tse)
|
||
|
- Ingmar Runge noticed that Windows config-win32.h configuration file
|
||
|
did not include a definition for HAVE_CLOSESOCKET which resulted in
|
||
|
function close() being inappropriately used to close sockets.
|
||
|
|
||
|
Version 1.7.0 (Nov 30, 2009)
|
||
|
|
||
|
* November 26, 2009 (Yang Tse)
|
||
|
- Larry Lansing fixed ares_parse_srv_reply to properly parse replies
|
||
|
which might contain non-SRV answers, skipping over potential non-SRV
|
||
|
ones such as CNAMEs.
|
||
|
|
||
|
* November 23, 2009 (Yang Tse)
|
||
|
- Changed naming convention for c-ares libraries built with MSVC, details
|
||
|
and build instructions provided in README.msvc file.
|
||
|
|
||
|
* November 22, 2009 (Yang Tse)
|
||
|
- Jakub Hrozek fixed more function prototypes in man pages to sync them
|
||
|
with the ones declared in ares.h
|
||
|
|
||
|
- Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and
|
||
|
ares_addr6ttl in order to prevent name space pollution, along with
|
||
|
necessary changes to code base and man pages.This change does not break
|
||
|
ABI, there is no need to recompile existing applications. But existing
|
||
|
applications using these structs with the old name will need source code
|
||
|
adjustments when recompiled using c-ares 1.7.0.
|
||
|
|
||
|
* November 21, 2009 (Yang Tse)
|
||
|
- Added manifest stuff to Makefile.msvc.
|
||
|
|
||
|
* November 20, 2009 (Yang Tse)
|
||
|
- Fixed several function prototypes in man pages that were out of sync
|
||
|
with the ones declared in ares.h. Added ares_free_data() along with
|
||
|
man page. Updated ares_parse_srv_reply() and ares_parse_txt_reply()
|
||
|
with changes from Jakub Hrozek making these now return linked lists
|
||
|
instead of arrays, and merging the ares_free_data() adjustments.
|
||
|
|
||
|
* November 10, 2009 (Yang Tse)
|
||
|
- Updated MSVC 6.0 project files to match settings from Makefile.msvc.
|
||
|
|
||
|
* November 9, 2009 (Yang Tse)
|
||
|
- Makefile.msvc is now the reference method to build c-ares and sample
|
||
|
programs with any MSVC compiler or MS Visual Studio version. If no
|
||
|
option or target are specified it builds dynamic and static c-ares
|
||
|
libraries in debug and release flavours and also builds all sample
|
||
|
programs using each of the different c-ares libraries.
|
||
|
|
||
|
* November 2, 2009 (Yang Tse)
|
||
|
- Renamed c-ares setup.h to ares_setup.h
|
||
|
|
||
|
* October 31, 2009 (Yang Tse)
|
||
|
- Symbol hiding configure options are named now --enable-symbol-hiding
|
||
|
and --disable-symbol-hiding in an attempt to make them less ambiguous.
|
||
|
|
||
|
* October 30, 2009 (Yang Tse)
|
||
|
- Many fixes for ares_parse_txt_reply()
|
||
|
|
||
|
* October 29, 2009 (Daniel Stenberg)
|
||
|
- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing
|
||
|
|
||
|
* October 29, 2009 (Yang Tse)
|
||
|
- Updated MSVC 6.0 workspace and project files that allows building
|
||
|
dynamic and static c-ares libraries in debug and release flavours.
|
||
|
Additionally each of the three sample programs is built against
|
||
|
each of the four possible c-ares libraries, generating all this
|
||
|
a total number of 12 executables and 4 libraries.
|
||
|
|
||
|
* October 28, 2009 (Yang Tse)
|
||
|
- Initial step towards the ability to reduce c-ares exported symbols
|
||
|
when built as a shared library based on the 'visibility' attribute
|
||
|
for GNUC and Intel compilers and based on __global for Sun compilers,
|
||
|
taking also in account __declspec function decoration for Win32 and
|
||
|
Symbian DLL's.
|
||
|
|
||
|
* October 27, 2009 (Yang Tse)
|
||
|
- Fixed Pelles C Win32 target compilation issues.
|
||
|
|
||
|
* October 23, 2009 (Yang Tse)
|
||
|
- John Engelhart noticed an unreleased problem relative to a duplicate
|
||
|
ARES_ECANCELLED error code value and missing error code description.
|
||
|
|
||
|
* October 7, 2009 (Yang Tse)
|
||
|
- Overhauled ares__get_hostent() Fixing out of bounds memory overwrite
|
||
|
triggered with malformed /etc/hosts file. Improving parsing of /etc/hosts
|
||
|
file. Validating requested address family. Ensuring that failures always
|
||
|
return a NULL pointer. Adjusting header inclusions.
|
||
|
|
||
|
* October 6, 2009 (Yang Tse)
|
||
|
- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak.
|
||
|
|
||
|
* September 29, 2009 (Yang Tse)
|
||
|
- Make configure script also check if _REENTRANT definition is required to
|
||
|
make errno available as a preprocessor macro.
|
||
|
|
||
|
* September 7, 2009 (Yang Tse)
|
||
|
- Add T_SRV portability check to ares_parse_srv_reply.c
|
||
|
|
||
|
* 4 Sep 2009 (Daniel Stenberg)
|
||
|
- Jakub Hrozek added ares_parse_srv_reply() for SRV parsing
|
||
|
|
||
|
* 3 Aug 2009 (Daniel Stenberg)
|
||
|
- Joshua Kwan fixed the init routine to fill in the defaults for stuff that
|
||
|
fails to get inited by other means. This fixes a case of when the c-ares
|
||
|
init fails when internet access is fone.
|
||
|
|
||
|
- Timo Teras changed the reason code used in the resolve callback done when
|
||
|
ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
|
||
|
better allow the callback to know what's happening.
|
||
|
|
||
|
* 14 Jul 2009 (Guenter Knauf)
|
||
|
- renamed generated config.h to ares_config.h to avoid any future clashes
|
||
|
with config.h from other projects.
|
||
|
|
||
|
* June 20 2009 (Yang Tse)
|
||
|
- Refactor how libraries are checked for connect() function in configure
|
||
|
script and check for connect() as it is done for other functions.
|
||
|
|
||
|
* June 19 2009 (Yang Tse)
|
||
|
- Make sclose() function-like macro definition used to close a socket,
|
||
|
now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
|
||
|
config file preprocessor definitions
|
||
|
|
||
|
* June 18 2009 (Yang Tse)
|
||
|
- Add CloseSocket camel case function check for configure script.
|
||
|
|
||
|
* June 17 2009 (Yang Tse)
|
||
|
- Check for socket() and closesocket() as it is done for other functions
|
||
|
in configure script.
|
||
|
|
||
|
* June 11 2009 (Yang Tse)
|
||
|
- Modified buildconf so that when automake runs it copies missing files
|
||
|
instead of symlinking them.
|
||
|
|
||
|
* June 8 2009 (Yang Tse)
|
||
|
- Removed buildconf.bat from release and daily snapshot archives. This
|
||
|
file is only for CVS tree checkout builds.
|
||
|
|
||
|
* May 26 2009 (Yang Tse)
|
||
|
- Added --enable-curldebug configure option to enable and disable building
|
||
|
with the low-level curl debug memory tracking 'feature' to allow decoupled
|
||
|
setting from --enable-debug, allowing again to build c-ares independently
|
||
|
out of the CVS tree.
|
||
|
|
||
|
For the c-ares library option --enable-debug enables debug build features
|
||
|
which are _not_ related with memory tracking. For the c-ares library when
|
||
|
--enable-debug is given it does not enable the memory tracking feature. If
|
||
|
you wish to enable the curl debug memory tracking you must use configure
|
||
|
option --enable-curldebug explicitily to do so.
|
||
|
|
||
|
Internally, definition of preprocessor symbol DEBUGBUILD restricts code
|
||
|
which is only compiled for debug enabled builds. And symbol CURLDEBUG is
|
||
|
used to differentiate code which is _only_ used for memory tracking.
|
||
|
|
||
|
Make ares_init(), ares_dup() and ares_init_options() fail returning
|
||
|
ARES_ENOTINITIALIZED if library initialization has not been performed
|
||
|
calling ares_library_init().
|
||
|
|
||
|
* May 20 2009 (Yang Tse)
|
||
|
- Added ares_library_init() and ares_library_cleanup() man pages.
|
||
|
|
||
|
* May 19 2009 (Yang Tse)
|
||
|
- Introduced ares_library_init() and ares_library_cleanup() functions.
|
||
|
|
||
|
This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets
|
||
|
using c-ares 1.7.0 can still survive without calling these functions. Read all
|
||
|
the details on ares_library_init(3) and ares_library_cleanup(3) man pages that
|
||
|
are included.
|
||
|
|
||
|
curl/libcurl 7.19.5 is fully compatible with c-ares 1.7.0 on all systems.
|
||
|
|
||
|
In order to use c-ares 1.7.0 with curl/libcurl on Win32/64 systems it is
|
||
|
required that curl/libcurl is 7.19.5 or newer. In other words, it is not
|
||
|
possible on Win32/64 to use c-ares 1.7.0 with a curl/libcurl version less
|
||
|
than 7.19.5
|
||
|
|
||
|
* May 11 2009 (Daniel Stenberg)
|
||
|
- Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to
|
||
|
only expose functions starting with ares_.
|
||
|
|
||
|
* May 7 2009 (Yang Tse)
|
||
|
- Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition
|
||
|
attempt in generated config.h
|
||
|
|
||
|
* May 2 2009 (Yang Tse)
|
||
|
- Use a build-time configured ares_socklen_t data type instead of socklen_t.
|
||
|
|
||
|
* April 21 2009 (Yang Tse)
|
||
|
- Moved potential inclusion of system's malloc.h and memory.h header files to
|
||
|
setup_once.h. Inclusion of each header file is based on the definition of
|
||
|
NEED_MALLOC_H and NEED_MEMORY_H respectively.
|
||
|
|
||
|
* March 11 2009 (Yang Tse)
|
||
|
- Japheth Cleaver fixed acountry.c replacing u_long with unsigned long.
|
||
|
|
||
|
* February 20 2009 (Yang Tse)
|
||
|
- Do not halt compilation when using VS2008 to build a Windows 2000 target.
|
||
|
|
||
|
* February 3 2009 (Phil Blundell)
|
||
|
- If the server returns garbage or nothing at all in response to an AAAA query,
|
||
|
go on and ask for A records anyway.
|
||
|
|
||
|
* January 31 2009 (Daniel Stenberg)
|
||
|
- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving
|
||
|
either AF_INET6 or AF_INET. It works by accepting any of the looksups in the
|
||
|
hosts file, and it resolves the AAAA field with a fallback to A.
|
||
|
|
||
|
* January 14 2009 (Daniel Stenberg)
|
||
|
- ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it
|
||
|
now declares the private struct ares_in6_addr for all systems instead of
|
||
|
relying on one possibly not present in the system.
|
||
|
|
||
|
* January 13 2009 (Phil Blundell)
|
||
|
- ares__send_query() now varies the retry timeout pseudo-randomly to avoid
|
||
|
packet storms when several queries were started at the same time.
|
||
|
|
||
|
* January 11 2009 (Daniel Stenberg)
|
||
|
- Phil Blundell added the internal function ares__expand_name_for_response()
|
||
|
that is now used by the ares_parse_*_reply() functions instead of the
|
||
|
ares_expand_name() simply to easier return ARES_EBADRESP for the cases where
|
||
|
the name expansion fails as in responses that really isn't expected.
|
||
|
|
||
|
Version 1.6.0 (Dec 9, 2008)
|
||
|
|
||
|
* December 9 2008 (Gisle Vanem)
|
||
|
|
||
|
Fixes for Win32 targets using the Watt-32 tcp/ip stack.
|
||
|
|
||
|
* Dec 4 2008 (Daniel Stenberg)
|
||
|
|
||
|
Gregor Jasny provided the patch that introduces ares_set_socket_callback(),
|
||
|
and I edited it to also get duped by ares_dup().
|
||
|
|
||
|
* Dec 3 2008 (Daniel Stenberg)
|
||
|
|
||
|
API changes:
|
||
|
|
||
|
I made sure the public ares_config struct looks like before and yet it
|
||
|
supports the ROTATE option thanks to c-ares now storing the "optmask"
|
||
|
internally. Thus we should be ABI compatible with the past release(s)
|
||
|
now. My efforts mentioned below should not break backwards ABI compliance.
|
||
|
|
||
|
Here's how I suggest we proceed with the API:
|
||
|
|
||
|
ares_init() will be primary "channel creator" function.
|
||
|
|
||
|
ares_init_options() will continue to work exactly like now and before. For
|
||
|
starters, it will be the (only) way to set the existing options.
|
||
|
|
||
|
ares_save_options() will continue to work like today, but will ONLY save
|
||
|
options that you can set today (including ARES_OPT_ROTATE actually) but new
|
||
|
options that we add may not be saved with this.
|
||
|
|
||
|
Instead we introduce:
|
||
|
|
||
|
ares_dup() that instead can make a new channel and clone the config used
|
||
|
from an existing channel. It will then clone all config options, including
|
||
|
future new things we add.
|
||
|
|
||
|
ares_set_*() style functions that set (new) config options. As a start we
|
||
|
simply add these for new functionality, but over time we can also introduce
|
||
|
them for existing "struct ares_options" so that we can eventually deprecate
|
||
|
the two ares_*_options() functions.
|
||
|
|
||
|
ares_get_*() style functions for extracting info from a channel handle that
|
||
|
should be used instead of ares_save_options().
|
||
|
|
||
|
* Nov 26 2008 (Yang Tse)
|
||
|
- Brad Spencer provided changes to allow buildconf to work on OS X.
|
||
|
|
||
|
- Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a
|
||
|
buffer to shrink instead of expand if a reply contained 8 or more records.
|
||
|
|
||
|
* Nov 25 2008 (Yang Tse)
|
||
|
- In preparation for the upcomming IPv6 nameservers patch, the internal
|
||
|
ares_addr union is now changed into an internal struct which also holds
|
||
|
the address family.
|
||
|
|
||
|
* Nov 19 2008 (Daniel Stenberg)
|
||
|
- Brad Spencer brought the new function ares_gethostbyname_file() which simply
|
||
|
resolves a host name from the given file, using the regular hosts syntax.
|
||
|
|
||
|
* Nov 1 2008 (Daniel Stenberg)
|
||
|
- Carlo Contavalli added support for the glibc "rotate" option, as documented
|
||
|
in man resolv.conf:
|
||
|
|
||
|
causes round robin selection of nameservers from among those listed. This
|
||
|
has the effect of spreading the query load among all listed servers, rather
|
||
|
than having all clients try the first listed server first every time.
|
||
|
|
||
|
You can enable it with ARES_OPT_ROTATE
|
||
|
|
||
|
* Oct 21 2008 (Yang Tse)
|
||
|
Charles Hardin added handling of EINPROGRESS for UDP connects.
|
||
|
|
||
|
* Oct 18 2008 (Daniel Stenberg)
|
||
|
Charles Hardin made adig support a regular numerical dotted IP address for the
|
||
|
-s option as well.
|
||
|
|
||
|
* Oct 7 2008 (Yang Tse)
|
||
|
- Added --enable-optimize configure option to enable and disable compiler
|
||
|
optimizations to allow decoupled setting from --enable-debug.
|
||
|
|
||
|
* Oct 2 2008 (Yang Tse)
|
||
|
- Added --enable-warnings configure option to enable and disable strict
|
||
|
compiler warnings to allow decoupled setting from --enable-debug.
|
||
|
|
||
|
* Sep 17 2008 (Yang Tse)
|
||
|
- Code reorganization to allow internal/private use of "nameser.h" to any
|
||
|
system that lacks arpa/nameser.h or arpa/nameser_compat.h header files.
|
||
|
|
||
|
* Sep 16 2008 (Yang Tse)
|
||
|
- Code reorganization to allow internal/private use of ares_writev to any
|
||
|
system that lacks the writev function.
|
||
|
|
||
|
* Sep 15 2008 (Yang Tse)
|
||
|
- Code reorganization to allow internal/private use of ares_strcasecmp to any
|
||
|
system that lacks the strcasecmp function.
|
||
|
|
||
|
- Improve configure detection of some string functions.
|
||
|
|
||
|
* Sep 11 2008 (Yang Tse)
|
||
|
- Code reorganization to allow internal/private use of ares_strdup to any
|
||
|
system that lacks the strdup function.
|
||
|
|
||
|
Version 1.5.3 (Aug 29, 2008)
|
||
|
|
||
|
* Aug 25 2008 (Yang Tse)
|
||
|
- Improvement by Brad House:
|
||
|
|
||
|
This patch addresses an issue in which a response could be sent back to the
|
||
|
source port of a client from a different address than the request was made to.
|
||
|
This is one form of a DNS cache poisoning attack.
|
||
|
|
||
|
The patch simply uses recvfrom() rather than recv() and validates that the
|
||
|
address returned from recvfrom() matches the address of the server we have
|
||

connected to. Only necessary on UDP sockets as they are connection-less, TCP
|

|
is unaffected.

- Fix by George Neill:
|
||
|
Fixed compilation of acountry sample application failure on some systems.
|
||
|
|
||
|
* Aug 4 2008 (Daniel Stenberg)
|
||
|
- Fix by Tofu Linden:
|
||
|
|
||
|
The symptom:
|
||
|
* Users (usually, but not always) on 2-Wire routers and the Comcast service
|
||
|
and a wired connection to their router would find that the second and
|
||
|
subsequent DNS lookups from fresh processes using c-ares to resolve the same
|
||
|
address would cause the process to never see a reply (it keeps polling for
|
||
|
around 1m15s before giving up).
|
||
|
|
||
|
The repro:
|
||
|
* On such a machine (and yeah, it took us a lot of QA to find the systems
|
||
|
that reproduce such a specific problem!), do 'ahost www.secondlife.com',
|
||
|
then do it again. The first process's lookup will work, subsequent lookups
|
||
|
will time-out and fail.
|
||
|
|
||
|
The cause:
|
||
|
* init_id_key() was calling randomize_key() *before* it initialized
|
||
|
key->state, meaning that the randomness generated by randomize_key() is
|
||
|
immediately overwritten with deterministic values. (/dev/urandom was also
|
||
|
being read incorrectly in the c-ares version we were using, but this was
|
||
|
fixed in a later version.)
|
||
|
* This makes the stream of generated query-IDs from any new c-ares process
|
||
|
be an identical and predictable sequence of IDs.
|
||
|
* This makes the 2-Wire's default built-in DNS server detect these queries
|
||
|
as probable-duplicates and (erroneously) not respond at all.
|
||
|
|
||
|
|
||
|
* Aug 4 2008 (Yang Tse)
|
||
|
- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
|
||
|
Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62
|
||
|
version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols
|
||
|
no matter if the system is AIX or not. To keep the traditional behaviour,
|
||
|
and an uniform one across autoconf versions AC_AIX is replaced with our
|
||
|
own internal macro CARES_CHECK_AIX_ALL_SOURCE.
|
||
|
|
||
|
* Aug 1 2008 (Yang Tse)
|
||
|
- Configure process now checks if the preprocessor _REENTRANT symbol is already
|
||
|
defined. If it isn't currently defined a set of checks are performed to test
|
||
|
if its definition is required to make visible to the compiler a set of *_r
|
||
|
functions. Finally, if _REENTRANT is already defined or needed it takes care
|
||
|
of making adjustments necessary to ensure that it is defined equally for the
|
||
|
configure process tests and generated config file.
|
||
|
|
||
|
* Jul 20 2008 (Yang Tse)
|
||
|
- When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
|
||
|
now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID,
|
||
|
RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID.
|
||
|
|
||
|
* Jul 17 2008 (Yang Tse)
|
||
|
- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined
|
||
|
to the data type pointed by its respective argument and not the pointer type.
|
||
|
|
||
|
* Jul 16 2008 (Yang Tse)
|
||
|
- Improved configure detection of number of arguments for getservbyport_r.
|
||
|
Detection is now based on compilation checks instead of linker ones.
|
||
|
|
||
|
- Configure process now checks availability of recvfrom() socket function and
|
||
|
finds out its return type and the types of its arguments. Added definitions
|
||
|
for non-configure systems config files, and introduced macro sreadfrom which
|
||
|
will be used on udp sockets as a recvfrom() wrapper in the future.
|
||
|
|
||
|
* Jul 15 2008 (Yang Tse)
|
||
|
- Introduce definition of _REENTRANT symbol in setup.h to improve library
|
||
|
usability. Previously the configure process only used the AC_SYS_LARGEFILE
|
||
|
macro for debug builds, now it is also used for non-debug ones enabling the
|
||
|
use of configure options --enable-largefile and --disable-largefile which
|
||
|
might be needed for library compatibility. Remove checking the size of
|
||
|
curl_off_t, it is no longer needed.
|
||
|
|
||
|
* Jul 3 2008 (Daniel Stenberg)
|
||
|
- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and
|
||
|
the target host has only A records, it automatically falls back to an
|
||
|
AF_INET lookup and gives you the A results. However, if the target host has
|
||
|
a CNAME record, this behaviour is defeated since the original query does
|
||
|
return some data even though ares_parse_aaa_reply() doesn't consider it
|
||
|
relevant. Here's a small patch to make it behave the same with and without
|
||
|
the CNAME.
|
||
|
|
||
|
* Jul 2 2008 (Yang Tse)
|
||
|
- Fallback to gettimeofday when monotonic clock is unavailable at run-time.
|
||
|
|
||
|
* Jun 30 2008 (Daniel Stenberg)
|
||
|
|
||
|
- As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is
|
||
|
not posix or anything and thus c-ares failed to build on hurd (and possibly
|
||
|
elsewhere). The define was also somewhat artificially used in the windows
|
||
|
port. Now, I instead rewrote the use of gethostbyname to enlarge the host
|
||
|
name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN
|
||
|
define. I thus also removed the defien from the namser.h file where it was
|
||
|
once added for the windows build.
|
||
|
|
||
|
I also fixed init_by_defaults() function to not leak memory in case if
|
||
|
error.
|
||
|
|
||
|
* Jun 9 2008 (Yang Tse)
|
||
|
|
||
|
- Make libcares.pc generated file for pkg-config include information relative
|
||
|
to the libraries needed for the static linking of c-ares.
|
||
|
|
||
|
* May 30 2008 (Yang Tse)
|
||
|
|
||
|
- Brad House fixed a missing header file inclusion in adig sample program.
|
||
|
|
||
|
Version 1.5.2 (May 29, 2008)
|
||
|
|
||
|
* May 13 2008 (Daniel Stenberg)
|
||
|
|
||
|
- Introducing millisecond resolution support for the timeout option. See
|
||
|
ares_init_options()'s ARES_OPT_TIMEOUTMS.
|
||
|
|
||
|
* May 9 2008 (Yang Tse)
|
||
|
|
||
|
- Use monotonic time source if available, for private function ares__tvnow()
|
||
|
|
||
|
* May 7 2008 (Daniel Stenberg)
|
||
|
|
||
|
- Sebastian made c-ares able to return all PTR-records when doing reverse
|
||
|
lookups. It is not common practice to have multiple PTR-Records for a single
|
||
|
IP, but its perfectly legal and some sites have those.
|
||
|
|
||
|
- Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to
|
||
|
autoconf 2.57 usage (which is the version you have specified as the minimum
|
||
|
version). It's a minor change but it does clean up some warnings with newer
|
||
|
autoconf (specifically 2.62).
|
||
|
|
||
|
* May 5 2008 (Yang Tse)
|
||
|
|
||
|
- Improved parsing of resolver configuration files.
|
||
|
|
||
|
* April 4 2008 (Daniel Stenberg)
|
||
|
|
||
|
- Eino Tuominen improved the code when a file is used to seed the randomizer.
|
||
|
|
||
|
- Alexey Simak made adig support NAPTR records
|
||
|
|
||
|
- Alexey Simak fixed the VC dsp file by adding the missing source file
|
||
|
ares_expand_string.c
|
||
|
|
||
|
* December 11 2007 (Gisle Vanem)
|
||
|
|
||
|
- Added another sample application; acountry.c which converts an
|
||
|
IPv4-address(es) and/or host-name(s) to country-name and country-code.
|
||
|
This uses the service of the DNSBL at countries.nerd.dk.
|
||
|
|
||
|
* December 3 2007 (Daniel Stenberg)
|
||
|
|
||
|
- Brad Spencer fixed the configure script to assume that there's no
|
||
|
/dev/urandom when built cross-compiled as then the script cannot check for
|
||
|
it.
|
||
|
|
||
|
- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat
|
||
|
|
||
|
Version 1.5.1 (Nov 21, 2007)
|
||
|
|
||
|
* November 21 2007 (Daniel Stenberg)
|
||
|
|
||
|
- Robin Cornelius pointed out that ares_llist.h was missing in the release
|
||
|
archive for 1.5.0
|
||
|
|
||
|
Version 1.5.0 (Nov 21, 2007)
|
||
|
|
||
|
* October 2 2007 (Daniel Stenberg)
|
||
|
|
||
|
- ares_strerror() segfaulted if the input error number was out of the currently
|
||
|
supported range.
|
||
|
|
||
|
- Yang Tse: Avoid a segfault when generating a DNS "Transaction ID" in
|
||
|
internal function init_id_key() under low memory conditions.
|
||
|
|
||
|
* September 28 2007 (Daniel Stenberg)
|
||
|
|
||
|
- Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI
|
||
|
and API changes in the progress callback (and possibly more coming up from
|
||
|
Steinar)
|
||
|
|
||
|
* September 28 2007 (Steinar H. Gunderson)
|
||
|
|
||
|
- Don't skip a server if it's the only one. (Bugfix from the Google tree.)
|
||
|
|
||
|
- Made the query callbacks receive the number of timeouts that happened during
|
||
|
the execution of a query, and updated documentation accordingly. (Patch from
|
||
|
the Google tree.)
|
||
|
|
||
|
- Support a few more socket options: ARES_OPT_SOCK_SNDBUF and
|
||
|
ARES_OPT_SOCK_RCVBUF
|
||
|
|
||
|
- Always register for TCP events even if there are no outstanding queries, as
|
||
|
the other side could always close the connection, which is a valid event
|
||
|
which should be responded to.
|
||
|
|
||
|
* September 22 2007 (Daniel Stenberg)
|
||
|
|
||
|
- Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in
|
||
|
several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that
|
||
|
if it fails and the socket is closed the following code doesn't try to use
|
||
|
the file descriptor.
|
||
|
|
||
|
- Steinar H. Gunderson modified c-ares to now also do to DNS retries even when
|
||
|
TCP is used since there are several edge cases where it still makes sense.
|
||
|
|
||
|
- Brad House provided a fix for ares_save_options():
|
||
|
|
||
|
Apparently I overlooked something with the ares_save_options() where it
|
||
|
would try to do a malloc(0) when no options of that type needed to be saved.
|
||
|
On most platforms, this was fine because malloc(0) doesn't actually return
|
||
|
NULL, but on AIX it does, so ares_save_options would return ARES_ENOMEM.
|
||
|
|
||
|
* July 14 2007 (Daniel Stenberg)
|
||
|
|
||
|
- Vlad Dinulescu fixed two outstanding valgrind reports:
|
||
|
|
||
|
1. In ares_query.c , in find_query_by_id we compare q->qid (which is a short
|
||
|
int variable) with qid, which is declared as an int variable. Moreover,
|
||
|
DNS_HEADER_SET_QID is used to set the value of qid, but DNS_HEADER_SET_QID
|
||
|
sets only the first two bytes of qid. I think that qid should be declared as
|
||
|
"unsigned short" in this function.
|
||
|
|
||
|
2. The same problem occurs in ares_process.c, process_answer() . query->qid
|
||
|
(an unsigned short integer variable) is compared with id, which is an
|
||
|
integer variable. Moreover, id is initialized from DNS_HEADER_QID which sets
|
||
|
only the first two bytes of id. I think that the id variable should be
|
||
|
declared as "unsigned short" in this function.
|
||
|
|
||
|
Even after declaring these variables as "unsigned short", the valgrind
|
||
|
errors are still there. Which brings us to the third problem.
|
||
|
|
||
|
3. The third problem is that Valgrind assumes that query->qid is not
|
||
|
initialised correctly. And it does that because query->qid is set from
|
||
|
DNS_HEADER_QID(qbuf); Valgrind says that qbuf has unitialised bytes. And
|
||
|
qbuf has uninitialised bytes because of channel->next_id . And next_id is
|
||
|
set by ares_init.c:ares__generate_new_id() . I found that putting short r=0
|
||
|
in this function (instead of short r) makes all Valgrind warnings go away.
|
||
|
I have studied ares__rc4() too, and this is the offending line:
|
||
|
|
||
|
buffer_ptr[counter] ^= state[xorIndex]; (ares_query.c:62)
|
||
|
|
||
|
This is what triggers Valgrind.. buffer_ptr is unitialised in this function,
|
||
|
and by applying ^= on it, it remains unitialised.
|
||
|
|
||
|
Version 1.4.0 (June 8, 2007)
|
||
|
|
||
|
* June 4 2007 (Daniel Stenberg)
|
||
|
|
||
|
- James Bursa reported a major memory problem when resolving multi-IP names
|
||
|
and I found and fixed the problem. It was added by Ashish Sharma's patch
|
||
|
two days ago.
|
||
|
|
||
|
When I then tried to verify multiple entries in /etc/hosts after my fix, I
|
||
|
got another segfault and decided this code was not ripe for inclusion and I
|
||
|
reverted the patch.
|
||
|
|
||
|
* June 2 2007
|
||
|
|
||
|
- Brad Spencer found and fixed three flaws in the code, found with the new
|
||
|
gcc 4.2.0 warning: -Waddress
|
||
|
|
||
|
- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
|
||
|
He also made recent Microsoft compilers use _strdup() instead of strdup().
|
||
|
|
||
|
- Brad House's man pages for ares_save_options() and ares_destroy_options()
|
||
|
were added.
|
||
|
|
||
|
- Ashish Sharma provided a patch for supporting multiple entries in the
|
||
|
/etc/hosts file. Patch edited for coding style and functionality by me
|
||
|
(Daniel).
|
||
|
|
||
|
* May 30 2007
|
||
|
|
||
|
- Shmulik Regev brought cryptographically secure transaction IDs:
|
||
|
|
||
|
The c-ares library implementation uses a DNS "Transaction ID" field that is
|
||
|
seeded with a pseudo random number (based on gettimeofday) which is
|
||
|
incremented (++) between consecutive calls and is therefore rather
|
||
|
predictable. In general, predictability of DNS Transaction ID is a well
|
||
|
known security problem (e.g.
|
||
|
http://bak.spc.org/dms/archive/dns_id_attack.txt) and makes a c-ares based
|
||
|
implementation vulnerable to DNS poisoning. Credit goes to Amit Klein
|
||
|
(Trusteer) for identifying this problem.
|
||
|
|
||
|
The patch I wrote changes the implementation to use a more secure way of
|
||
|
generating unique IDs. It starts by obtaining a key with reasonable entropy
|
||
|
which is used with an RC4 stream to generate the cryptographically secure
|
||
|
transaction IDs.
|
||
|
|
||
|
Note that the key generation code (in ares_init:randomize_key) has two
|
||
|
versions, the Windows specific one uses a cryptographically safe function
|
||
|
provided (but undocumented :) by the operating system (described at
|
||
|
http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx). The
|
||
|
default implementation is a bit naive and uses the standard 'rand'
|
||
|
function. Surely a better way to generate random keys exists for other
|
||
|
platforms.
|
||
|
|
||
|
The patch can be tested by using the adig utility and using the '-s' option.
|
||
|
|
||
|
- Brad House added ares_save_options() and ares_destroy_options() that can be
|
||
|
used to keep options for later re-usal when ares_init_options() is used.
|
||
|
|
||
|
Problem: Calling ares_init() for each lookup can be unnecessarily resource
|
||
|
intensive. On windows, it must LoadLibrary() or search the registry
|
||
|
on each call to ares_init(). On unix, it must read and parse
|
||
|
multiple files to obtain the necessary configuration information. In
|
||
|
a single-threaded environment, it would make sense to only
|
||
|
ares_init() once, but in a heavily multi-threaded environment, it is
|
||
|
undesirable to ares_init() and ares_destroy() for each thread created
|
||
|
and track that.
|
||
|
|
||
|
Solution: Create ares_save_options() and ares_destroy_options() functions to
|
||
|
retrieve and free options obtained from an initialized channel. The
|
||
|
options populated can be used to pass back into ares_init_options(),
|
||
|
it should populate all needed fields and not retrieve any information
|
||
|
from the system. Probably wise to destroy the cache every minute or
|
||
|
so to prevent the data from becoming stale.
|
||
|
|
||
|
- Daniel S added ares_process_fd() to allow applications to ask for processing
|
||
|
on specific sockets and thus avoiding select() and associated
|
||
|
functions/macros. This function will be used by upcoming libcurl releases
|
||
|
for this very reason. It also made me export the ares_socket_t type in the
|
||
|
public ares.h header file, since ares_process_fd() uses that type for two of
|
||
|
the arguments.
|
||
|
|
||
|
* May 25 2007
|
||
|
|
||
|
- Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows
|
||
|
that could cause it to return a bad return code.
|
||
|
|
||
|
* April 16 2007
|
||
|
|
||
|
- Yang Tse: Provide ares_getopt() command-line parser function as a source
|
||
|
code helper function, not belonging to the actual c-ares library.
|
||
|
|
||
|
* February 19 2007
|
||
|
|
||
|
- Vlad Dinulescu added ares_parse_ns_reply().
|
||
|
|
||
|
* February 13 2007
|
||
|
|
||
|
- Yang Tse: Fix failure to get the search sequence of /etc/hosts and
|
||
|
DNS from /etc/nsswitch.conf, /etc/host.conf or /etc/svc.conf when
|
||
|
/etc/resolv.conf did not exist or was unable to read it.
|
||
|
|
||
|
* November 22 2006
|
||
|
|
||
|
- Install ares_dns.h too
|
||
|
|
||
|
- Michael Wallner fixed this problem: When I set domains in the options
|
||
|
struct, and there are domain/search entries in /etc/resolv.conf, the domains
|
||
|
of the options struct will be overridden.
|
||
|
|
||
|
* November 6 2006
|
||
|
|
||
|
- Yang Tse removed a couple of potential zero size memory allocations.
|
||
|
|
||
|
- Andreas Rieke fixed the line endings in the areslib.dsp file that I (Daniel)
|
||
|
broke in the 1.3.2 release. We should switch to a system where that file is
|
||
|
auto-generated. We could rip some code for that from curl...
|
||
|
|
||
|
Version 1.3.2 (November 3, 2006)
|
||
|
|
||
|
* October 12 2006
|
||
|
|
||
|
- Prevent ares_getsock() to overflow if more than 16 sockets are used.
|
||
|
|
||
|
* September 11 2006
|
||
|
|
||
|
- Guilherme Balena Versiani: I noted a strange BUG in Win32 port
|
||
|
(ares_init.c/get_iphlpapi_dns_info() function): when I disable the network
|
||
|
by hand or disconnect the network cable in Windows 2000 or Windows XP, my
|
||
|
application gets 127.0.0.1 as the only name server. The problem comes from
|
||
|
'GetNetworkParams' function, that returns the empty string "" as the only
|
||
|
name server in that case. Moreover, the Windows implementation of
|
||
|
inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE.
|
||
|
|
||
|
* August 29 2006
|
||
|
|
||
|
- Brad Spencer did
|
||
|
|
||
|
o made ares_version.h use extern "C" for c++ compilers
|
||
|
o fixed compiler warnings in ares_getnameinfo.c
|
||
|
o fixed a buffer position init for TCP reads
|
||
|
|
||
|
* August 3 2006
|
||
|
|
||
|
- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
|
||
|
not always zero!
|
||
|
|

Version 1.3.1 (June 24, 2006)
|
||
|
|
||
|
* July 23, 2006
|
||
|
|
||
|
- Gisle Vanem added getopt() to the ahost program. Currently accepts
|
||
|
only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
|
||
|
|
||
|
* June 19, 2006
|
||
|
|
||
|
- (wahern) Removed "big endian" DNS section and RR data integer parser
|
||
|
macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise
|
||
|
operations in C operate on logical values. And in any event the octets are
|
||
|
already in big-endian (aka network) byte order so they're being reversed
|
||
|
(thus the source of the breakage).
|
||
|
|
||
|
* June 18, 2006
|
||
|
|
||
|
- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
|
||
|
from area_process.c.
|
||
|
|
||
|
TODO: Handle one last EAGAIN for a UDP socket send(2) in
|
||
|
ares__send_query().
|
||
|
|
||
|
* May 10, 2006
|
||
|
|
||
|
- Bram Matthys brought my attention to a libtool peculiarity where detecting
|
||
|
things such as C++ compiler actually is a bad thing and since we don't need
|
||
|
that detection I added a work-around, much inspired by a previous patch by
|
||
|
Paolo Bonzini. This also shortens the configure script quite a lot.
|
||
|
|
||
|
* May 3, 2006
|
||
|
|
||
|
- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes
|
||
|
c-ares call a callback on socket state changes. A better way than the
|
||
|
ares_getsock() to get full control over the socket state.
|
||
|
|
||
|
* January 9, 2006
|
||
|
|
||
|
- Alexander Lazic improved the getservbyport_r() configure check.
|
||
|
|
||
|
* January 6, 2006
|
||
|
|
||
|
- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
|
||
|
variable for easier controlling what it does and how it runs.
|
||
|
|
||
|
* January 5, 2006
|
||
|
|
||
|
- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it
|
||
|
build with newer gcc versions that no longer defines "riscos".
|
||
|
|
||
|
* December 22
|
||
|
|
||
|
- Daniel Stenberg added ares_getsock() that extracts the set of sockets to
|
||
|
wait for action on. Similar to ares_fds() but not restricted to using
|
||
|
select() for the waiting.
|
||
|
|
||
|
* November 25
|
||
|
|
||
|
- Yang Tse fixed some send() / recv() compiler warnings
|
||
|
|
||
|
* September 18
|
||
|
|
||
|
- Added constants that will be used by ares_getaddrinfo
|
||
|
|
||
|
- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it
|
||
|
is available to ensure it works properly in a threaded environment.
|
||
|
|
||
|
* September 10
|
||
|
|
||
|
- configure fix for detecting a member in the sockaddr_in6 struct which failed
|
||
|
on ipv6-enabled HP-UX 11.00
|
||
|
|
||
|
Version 1.3.0 (August 29, 2005)
|
||
|
|
||
|
* August 21
|
||
|
|
||
|
- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info()
|
||
|
when getting the DNS server etc.
|
||
|
|
||
|
* June 19
|
||
|
|
||
|
- Added some checks for the addrinfo structure.
|
||
|
|
||
|
* June 2
|
||
|
|
||
|
- William Ahern:
|
||
|
|
||
|
Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a
|
||
|
read event can come back from poll() on a valid SOCK_DGRAM socket but
|
||
|
recv(2) will still block. This patch doesn't ignore EAGAIN in
|
||
|
read_udp_packets(), though maybe it should. (This patch was edited by Daniel
|
||
|
Stenberg and a new configure test was added (imported from curl's configure)
|
||
|
to properly detect what non-blocking socket approach to use.)
|
||
|
|
||
|
I'm not quite sure how this was happening, but I've been seeing PTR queries
|
||
|
which seem to return empty responses. At least, they were empty when calling
|
||
|
ares_expand_name() on the record. Here's a patch which guarantees to
|
||
|
NUL-terminate the expanded name. The old behavior failed to NUL-terminate if
|
||
|
len was 0, and this was causing strlen() to run past the end of the buffer
|
||
|
after calling ares_expand_name() and getting ARES_SUCCESS as the return
|
||
|
value. If q is not greater than *s then it's equal and *s is always
|
||
|
allocated with at least one byte.
|
||
|
|
||
|
* May 16
|
||
|
|
||
|
- Added ares_getnameinfo which mimics the getnameinfo API (another feature
|
||
|
that could use testing).
|
||
|
|
||
|
* May 14
|
||
|
|
||
|
- Added an inet_ntop function from BIND for systems that do not have it.
|
||
|
|
||
|
* April 9
|
||
|
|
||
|
- Made sortlist support IPv6 (this can probably use some testing).
|
||
|
|
||
|
- Made sortlist support CIDR matching for IPv4.
|
||
|
|
||
|
* April 8
|
||
|
|
||
|
- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
|
||
|
does not work with IPv6. Also provided an implementation of bitncmp from
|
||
|
BIND for systems that do not supply this function. This will be used to add
|
||
|
IPv6 support to sortlist.
|
||
|
|
||
|
- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
|
||
|
The function can lookup IPv6 addresses both from files (/etc/hosts) and
|
||
|
DNS lookups.
|
||
|
|
||
|
* April 7
|
||
|
|
||
|
- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
|
||
|
OS X.
|
||
|
|
||
|
* April 5
|
||
|
|
||
|
- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
|
||
|
from BIND for systems that do not include these functions.
|
||
|
|
||
|
* March 11, 2005
|
||
|
|
||
|
- Dominick Meglio added ares_parse_aaaa_reply.c and did various
|
||
|
adjustments. The first little steps towards IPv6 support!
|
||
|
|
||
|
* November 7
|
||
|
|
||
|
- Fixed the VC project and makefile to use ares_cancel and ares_version
|
||
|
|
||
|
* October 24
|
||
|
|
||
|
- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw.
|
||
|
This is now fixed.
|
||
|
|
||
|
Version 1.2.1 (October 20, 2004)
|
||
|
|
||
|
* September 29
|
||
|
|
||
|
- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital
|
||
|
when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for
|
||
|
other OSes. He made c-ares check for and understand it if present.
|
||
|
|
||
|
- Now c-ares will use local host name lookup _before_ DNS resolving by default
|
||
|
if nothing else is told.
|
||
|
|
||
|
* September 26
|
||
|
|
||
|
- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf
|
||
|
file to determine the sequence in which to search /etc/hosts and DNS. So on
|
||
|
systems where this order is defined by /etc/host.conf instead of a "lookup"
|
||
|
entry in /etc/resolv.conf, c-ares will always default to looking in DNS
|
||
|
first, and /etc/hosts second.
|
||
|
|
||
|
c-ares now looks at
|
||
|
|
||
|
1) resolv.conf (for the "lookup" line);
|
||
|
2) nsswitch.fon (for the "hosts:" line);
|
||
|
3) host.conf (for the "order" line).
|
||
|
|
||
|
First match wins.
|
||
|
|
||
|
- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is
|
||
|
located in a static location. It assumed
|
||
|
C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact,
|
||
|
the location of the HOSTS file can be changed via a registry setting.
|
||
|
|
||
|
There is a key called DatabasePath which specifies the path to the HOSTS
|
||
|
file:
|
||
|
http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx
|
||
|
|
||
|
The patch will make c-ares correctly consult the registry for the location
|
||
|
of this file.
|
||
|
|
||
|
* August 29
|
||
|
|
||
|
- Gisle Vanem fixed the MSVC build files.
|
||
|
|
||
|
* August 20
|
||
|
|
||
|
- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
|
||
|
|
||
|
* August 13
|
||
|
|
||
|
- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
|
||
|
fine with MSVC 7.1
|
||
|
|
||
|
* July 24
|
||
|
|
||
|
- Made the lib get built static only if --enable-debug is used.
|
||
|
|
||
|
- Gisle Vanem fixed:
|
||
|
|
||
|
Basically in loops like handle_errors(), 'query->next' was assigned a local
|
||
|
variable and then query was referenced after the memory was freed by
|
||
|
next_server(). I've changed that so next_server() and end_query() returns
|
||
|
the next query. So callers should use this ret-value.
|
||
|
|
||
|
The next problem was that 'server->tcp_buffer_pos' had a random value at
|
||
|
entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
|
||
|
|
||
|
I've also added a ares_writev() for Windows to streamline the code a bit
|
||
|
more.
|
||
|
|
||
|
* July 20
|
||
|
- Fixed a few variable return types for some system calls. Made configure
|
||
|
check for ssize_t to make it possible to use that when receiving the send()
|
||
|
error code. This is necessary to prevent compiler warnings on some systems.
|
||
|
|
||
|
- Made configure create config.h, and all source files now include setup.h that
|
||
|
might include the proper config.h (or a handicrafted alternative).
|
||
|
|
||
|
- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
|
||
|
use 'int' for that.
|
||
|
|
||
|
- automake-ified and libool-ified c-ares. Now it builds libcares as a shared
|
||
|
lib on most platforms if wanted. (This bloated the size of the release
|
||
|
archive with another 200K!)
|
||
|
|
||
|
- Makefile.am now uses Makefile.inc for the c sources, h headers and man
|
||
|
pages, to make it easier for other makefiles to use the exact same set of
|
||
|
files.
|
||
|
|
||
|
- Adjusted 'maketgz' to use the new automake magic when building distribution
|
||
|
archives.
|
||
|
|
||
|
- Anyone desires HTML and/or PDF versions of the man pages in the release
|
||
|
archives?
|
||
|
|
||
|
* July 3
|
||
|
- G�nter Knauf made c-ares build and run on Novell Netware.
|
||
|
|
||
|
* July 1
|
||
|
- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp
|
||
|
fixes and made ares not use 'errno' to provide further info on Windows.
|
||
|
|
||
|
* June 30
|
||
|
- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.
|
||
|
|
||
|
* June 10
|
||
|
- Gisle Vanem's init patch for Windows:
|
||
|
|
||
|
The init_by_resolv_conf() function fetches the DNS-server(s)
|
||
|
from a series of registry branches.
|
||
|
|
||
|
This can be wrong in the case where DHCP has assigned nameservers, but the
|
||
|
user has overridden these servers with other prefered settings. Then it's
|
||
|
wrong to use the DHCPNAMESERVER setting in registry.
|
||
|
|
||
|
In the case of no global DHCP-assigned or fixed servers, but DNS server(s)
|
||
|
per adapter, one has to query the adapter branches. But how can c-ares know
|
||
|
which adapter is valid for use? AFAICS it can't. There could be one adapter
|
||
|
that is down (e.g. a VPN adapter).
|
||
|
|
||
|
So it's better to leave this to the IP Helper API (iphlapi) available in
|
||
|
Win-98/2000 and later. My patch falls-back to the old way if not available.
|
||
|
|
||
|
* June 8
|
||
|
- James Bursa fixed an init issue for RISC OS.
|
||
|
|
||
|
* May 11
|
||
|
- Nico Stappenbelt reported that when processing domain and search lines in
|
||
|
the resolv.conf file, the first entry encountered is processed and used as
|
||
|
the search list. According to the manual pages for both Linux, Solaris and
|
||
|
Tru64, the last entry of either a domain or a search field is used.
|
||
|
|
||
|
This is now adjusted in the code
|
||
|
|
||
|
Version 1.2.0 (April 13, 2004)
|
||
|
|
||
|
* April 2, 2004
|
||
|
- Updated various man pages to look nicer when converted to HTML on the web
|
||
|
site.
|
||
|
|
||
|
* April 1, 2004
|
||
|
- Dirk Manske provided a new function that is now named ares_cancel(). It is
|
||
|
used to cancel/cleanup a resolve/request made using ares functions on the
|
||
|
given ares channel. It does not destroy/kill the ares channel itself.
|
||
|
|
||
|
- Dominick Meglio cleaned up the formatting in several man pages.
|
||
|
|
||
|
* March 30, 2004
|
||
|
- Dominick Meglio's new ares_expand_string. A helper function when decoding
|
||
|
incoming DNS packages.
|
||
|
|
||
|
- Daniel Stenberg modified the Makefile.in to use a for loop for the man page
|
||
|
installation to improve overview and make it easier to add man pages.
|
||
|
|
||
|
Version 1.1.0 (March 11, 2004)
|
||
|
|
||
|
* March 9, 2004
|
||
|
- Gisle Vanem improved build on Windows.
|
||
|
|
||
|
* February 25, 2004
|
||
|
- Dan Fandrich found a flaw in the Feb 22 fix.
|
||
|
|
||
|
- Added better configure --enable-debug logic (taken from the curl configure
|
||
|
script). Added acinclude.m4 to the tarball.
|
||
|
|
||
|
* February 23, 2004
|
||
|
- Removed ares_free_errmem(), the function, the file and the man page. It was
|
||
|
not used and it did nothing.
|
||
|
|
||
|
- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
|
||
|
compiler warnings on picky compilers.
|
||
|
|
||
|
* February 22, 2004
|
||
|
- Dominick Meglio made ares init support multiple name servers in the
|
||
|
NameServer key on Windows.
|
||
|
|
||
|
* February 16, 2004
|
||
|
- Modified ares_private.h to include libcurl's memory debug header if
|
||
|
CURLDEBUG is set. This makes all the ares-functions supervised properly by
|
||
|
the curl test suite. This also forced me to add inclusion of the
|
||
|
ares_private.h header in a few more files that are using some kind of
|
||
|
memory-related resources.
|
||
|
|
||
|
- Made the makefile only build ahost and adig if 'make demos' is used.
|
||
|
|
||
|
* February 10, 2004
|
||
|
- Dirk Manske made ares_version.h installed with 'make install'
|
||
|
|
||
|
* February 4, 2004
|
||
|
- ares_free_errmem() is subject for removal, it is simply present for future
|
||
|
purposes, and since we removed the extra parameter in strerror() it won't
|
||
|
be used by c-ares!
|
||
|
- configure --enable-debug now enables picky compiler options if gcc is used
|
||
|
- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk
|
||
|
reported
|
||
|
|
||
|
Version 1.0.0 (February 3, 2004)
|
||
|
|
||
|
* February 3, 2004
|
||
|
- now we produce the libcares.a library instead of the previous libares.a
|
||
|
since we are no longer compatible
|
||
|
|
||
|
* February 2, 2004
|
||
|
|
||
|
- ares_strerror() has one argument less. This is the first official
|
||
|
modification of the existing provided ares API.
|
||
|
|
||
|
* January 29, 2004
|
||
|
|
||
|
- Dirk Manske fixed how the socket is set non-blocking.
|
||
|
|
||
|
* January 4, 2004
|
||
|
|
||
|
- Dominick Meglio made the private gettimeofday() become ares_gettimeofday()
|
||
|
instead in order to not pollute the name space and risk colliding with
|
||
|
other libraries' versions of this function.
|
||
|
|
||
|
* October 24, 2003. Daniel Stenberg
|
||
|
|
||
|
Added ares_version().
|
||
|
|
||
|
Version 1.0-pre1 (8 October 2003)
|
||
|
|
||
|
- James Bursa made it run on RISC OS
|
||
|
|
||
|
- Dominick Meglio made it run fine on NT4
|
||
|
|
||
|
- Duncan Wilcox made it work fine on Mac OS X
|
||
|
|
||
|
- Daniel Stenberg adjusted the windows port
|
||
|
|
||
|
- liren at vivisimo.com made the initial windows port
|
||
|
|
||
|
* Imported the sources from ares 1.1.1
|
