Yang Tse	2b838e85e7	George Neill's fix acountry sample application compilation failure.	17 years ago
Yang Tse	09d10cb5c5	Brad House's validation that DNS response address matches the request address	17 years ago
Daniel Stenberg	3f1bde7664	- 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.	17 years ago
Yang Tse	5c5e64b2f5	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.	17 years ago

Yang Tse	44ae9e4697	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.	17 years ago
Yang Tse	2aeb0314f5	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.	17 years ago
Yang Tse	7dd6d7cbe1	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.	17 years ago
Yang Tse	b95f5e5bed	Improved configure detection of number of arguments for getservbyport_r	17 years ago
Yang Tse	e5e2cd5659	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.	17 years ago
Daniel Stenberg	93e7573628	- 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.	17 years ago
Yang Tse	cd1f1d080c	fallback to gettimeofday when monotonic clock is unavailable at run-time	17 years ago
Daniel Stenberg	705c749aa1	- 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.	17 years ago

Daniel Stenberg	46dbd9461a	- Introducing millisecond resolution support for the timeout option. See ares_init_options()'s ARES_OPT_TIMEOUTMS.	17 years ago
Yang Tse	0848b4fdaa	Use monotonic time source if available.	17 years ago
Daniel Stenberg	0645b841d0	- 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.	17 years ago
Daniel Stenberg	3994a0be7f	- 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).	17 years ago
Yang Tse	fc4704b4d8	Improved parsing of resolver configuration files	17 years ago

Daniel Stenberg	aae96300a4	Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat	17 years ago
Daniel Stenberg	dc0e93d89e	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.	17 years ago

Daniel Stenberg	73b3390b83	change	17 years ago
Yang Tse	a15a88a4e6	Avoid a segfault when generating a DNS "Transaction ID" in internal function init_id_key() under low memory conditions.	17 years ago
Daniel Stenberg	e4eb2d0e1d	ares_strerror() segfaulted if the input error number was out of the currently supported range.	17 years ago
Daniel Stenberg	c577d2455e	today's modifications by Steinar and me	17 years ago
Daniel Stenberg	b17bb1bb67	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.	17 years ago
Daniel Stenberg	eee17fc854	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.	17 years ago
Daniel Stenberg	2b43edc964	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.	17 years ago
Daniel Stenberg	278e8f3926	added Vlad's entire description of his valgrind fix	18 years ago

Daniel Stenberg	fc5a460e0e	Brad Spencer found and fixed three flaws in the code, found with the new gcc 4.2.0 warning: -Waddress	18 years ago
Daniel Stenberg	efa231bec5	Brad House fixed VS2005 compiler warnings due to time_t being 64bit. He also made recent Microsoft compilers use _strdup() instead of strdup().	18 years ago
Daniel Stenberg	4e27354b82	Ashish Sharma provided a patch for supporting multiple entries in the /etc/hosts file. Patch edited for coding style and functionality by me (Daniel).	18 years ago
Daniel Stenberg	7a77f24d26	Shmulik Regev brought cryptographically secure transaction IDs	18 years ago
Daniel Stenberg	f1440b2405	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.	18 years ago
Daniel Stenberg	8c35c65fc7	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.	18 years ago
Daniel Stenberg	557aad7b02	Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows that could cause it to return a bad return code.	18 years ago
Yang Tse	d741a92e20	ares_getopt() command-line parser function does not belong to actual c-ares library. It is just a convinience source code helper function for use in example programs adig.c and ahost.c	18 years ago
