Daniel Stenberg	f61fa37f40	Gregor Jasny provided the patch that introduces ares_set_socket_callback(), and I edited it to also get duped by ares_dup().	16 years ago
Dan Fandrich	36a6a6e175	Only set TCP_NODELAY when it exists	16 years ago
Yang Tse	65cafbe109	Refactor configure script detection of functions used to set sockets into non-blocking mode, and decouple function detection from function capability.	16 years ago
Daniel Stenberg	1a1b4eb4f2	- 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	16 years ago
Yang Tse	64c82d0853	Charles Hardin patch: - handles the EINPROGRESS for UDP connects - uses closesocket instead of close on some paths that were noticed	16 years ago
Yang Tse	f214b583f5	adjust inclusion of "nameser.h"	16 years ago
Yang Tse	c035f2d3a4	Functionality only possible if recvfrom() is available.	17 years ago
Yang Tse	09d10cb5c5	Brad House's validation that DNS response address matches the request address	17 years ago
Yang Tse	2265b9281c	fix compiler warning	17 years ago
Yang Tse	7cb1c3a215	millisecond resolution support followup	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
Daniel Stenberg	7829b79768	check for strings.h in configure and use it for the strcasecmp() proto	17 years ago
Yang Tse	3bac381e3f	Renamed internal function to avoid a variable shadowing it	17 years ago
Gisle Vanem	6ff970c067	'FD_CLOXEC' is meaningless on MSDOS/Watt-32.	17 years ago
Steinar H. Gunderson	f75d1172f8	Removed a piece of redundant code (process_answer already takes care of it).	17 years ago
Yang Tse	10df4bdba2	Fix compiler warning	17 years ago
Yang Tse	68aa62d76b	check availability of <netinet/tcp.h>	17 years ago
Steinar H. Gunderson	60519063ea	Use ISDIGIT instead of isdigit; fixes a gcc warning.	17 years ago
Steinar H. Gunderson	04e49e09dc	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.	17 years ago
Gisle Vanem	053ffe405d	Fix compiler warning in setsockopt().	17 years ago
Steinar H. Gunderson	13d4d28e11	TCP queries can time out too, not just UDP queries. (Patch from the Google tree.)	17 years ago
Steinar H. Gunderson	21feec7d2d	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.)	17 years ago
Steinar H. Gunderson	2f7d637426	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.)	17 years ago
Steinar H. Gunderson	c24cd24870	Forgot to include a few hunks from ares_process.c earlier. Fixing now.	17 years ago
Steinar H. Gunderson	56ffdcefe1	Support a few more socket options, and refactor the option setting a bit. (Patch from the Google tree.)	17 years ago
Steinar H. Gunderson	50ba81cd23	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.)	17 years ago
Steinar H. Gunderson	b669e17544	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.	17 years ago
Steinar H. Gunderson	a6a159dcad	Don't skip a server if it's the only one. (Bugfix from the Google tree.)	17 years ago
Daniel Stenberg	c97d91e349	wrong, revert the previous "fix" and instead check that the fd_set pointer is non-NULL before we FD_CLR	17 years ago
Daniel Stenberg	99f15b20e8	eek, fix the conditions to return on either problem instead of requiring both to occur	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	403b315a3b	Vlad Dinulescu fixed two outstanding valgrind reports	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	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
Gisle Vanem	a627160041	Removed inclusion of <sys/types.h> in .c-files since it's already included through "setup.h".	18 years ago
Yang Tse	915e774a42	Check for stdbool.h at configuration stage, and include it if available. Check for lowercase 'bool' type at configuration stage. If not available provide a suitable replacement with a type definition of 'unsigned char' in setup_once.h Move definitions of TRUE and FALSE to setup_once.h	18 years ago
Yang Tse	69fa447354	use macros ERRNO, SET_ERRNO(), SOCKERRNO and SET_SOCKERRNO() for errno handling	18 years ago
Gisle Vanem	5908d58da3	Use correct 3rd argument for ioctlsocket() under Watt-32.	18 years ago
Yang Tse	145117174e	compiler warning fix	18 years ago
Yang Tse	dd8b7df5dd	Compiler warning fix	18 years ago
Yang Tse	77ac18117c	Check for USE_WINSOCK instead of WIN32 where the check was done to verify winsock API availability.	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
Yang Tse	cf64c31aac	Fix compiler warnings.	19 years ago
Yang Tse	283737c856	Replace send() and recv() with swrite() and sread() macros.	19 years ago
Gisle Vanem	0a83c1e416	2nd try adding CVS id.	19 years ago
Yang Tse	fb7987171c	Fix compiler warning	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	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
Gisle Vanem	ac9950c3eb	Changes for PellesC for Win32. It needs <unistd.h> for 'ssize_t'. Hence the rearrangement in ares_process.c.	19 years ago
