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	403b315a3b	Vlad Dinulescu fixed two outstanding valgrind reports	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
Daniel Stenberg	c1bc4c19be	Vlad Dinulescu added ares_parse_ns_reply()	18 years ago
Yang Tse	6751a208d6	Fix c-ares failing 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.	18 years ago
Daniel Stenberg	6a59182e81	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.	18 years ago
Daniel Stenberg	bc76d02bc3	Install ares_dns.h too	18 years ago
Yang Tse	877966659d	avoid a couple of potential zero size memory allocations	18 years ago

Daniel Stenberg	a39a54189b	stand clear for release 1.3.2	18 years ago
Daniel Stenberg	8df5b67ab0	Prevent ares_getsock() to overflow if more than 16 sockets are used.	18 years ago
Daniel Stenberg	d3439e3332	- 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.	18 years ago
Daniel Stenberg	1bec3073dc	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	19 years ago
Daniel Stenberg	19fb255f9e	Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and not always zero!	19 years ago
Gisle Vanem	08ce30f216	Added getopt() processing.	19 years ago
Daniel Stenberg	0e07499e96	1.3.1	19 years ago
William Ahern	d1ad89f943	Remove "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).	19 years ago
William Ahern	70dbc3725d	Handle EAGAIN/EWOULDBLOCK readiness errors, which can occur for both TCP and UDP even when a poll(2) or select(2) suggest otherwise.	19 years ago
Daniel Stenberg	e75c876ac5	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.	19 years ago
Daniel Stenberg	22e34b53e4	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.	19 years ago
Daniel Stenberg	de713cb37d	Alexander Lazic improved the getservbyport_r() configure check.	19 years ago
Daniel Stenberg	7a03bdaf34	buildconf fixes	19 years ago
Daniel Stenberg	d07656e76d	James Bursa fixes: find the hosts file on RISC OS, and made it build with newer gcc versions that no longer defines "riscos".	19 years ago
Daniel Stenberg	7b650b80c1	added ares_getsock()	19 years ago
Daniel Stenberg	513f448061	Yang Tse fixed compiler warnings	19 years ago
Dominick Meglio	6afd5c16d3	Added constants that will be used by ares_getaddrinfo. Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it isavailable to ensure it works properly in a threaded environment	19 years ago
Daniel Stenberg	8df407ed7d	mention the configure change	19 years ago
Daniel Stenberg	7885baf74d	1.3.0 coming just up	20 years ago
Daniel Stenberg	a8bb249d07	Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info() when getting the DNS server etc.	20 years ago
Dominick Meglio	ebcf14a69b	Added some checks for the addrinfo structure.	20 years ago
Daniel Stenberg	4e9c5b2dbb	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.)	20 years ago
Daniel Stenberg	ae75ee1423	William Ahern: 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.	20 years ago
Dominick Meglio	aba0b775ea	Added ares_getnameinfo which mimics the getnameinfo API	20 years ago
Dominick Meglio	eeb6aa6b01	Added an inet_ntop function from BIND for systems that do not have it	20 years ago
