2008-05-08check for strings.h in configure and use it for the strcasecmp() protoDaniel Stenberg
2007-10-18Renamed internal function to avoid a variable shadowing itYang Tse
2007-10-08'FD_CLOXEC' is meaningless on MSDOS/Watt-32.Gisle Vanem
2007-10-04Removed a piece of redundant code (process_answer already takes care of it).Steinar H. Gunderson
2007-09-30Fix compiler warningYang Tse
2007-09-30check availability of <netinet/tcp.h>Yang Tse
2007-09-29Use ISDIGIT instead of isdigit; fixes a gcc warning.Steinar H. Gunderson
2007-09-29Previously, processing a large batch of timeouts was O(n^2) in the number ofSteinar H. Gunderson
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.
2007-09-29Fix compiler warning in setsockopt().Gisle Vanem
2007-09-29TCP queries can time out too, not just UDP queries. (Patch from the Google ↵Steinar H. Gunderson
tree.)
2007-09-29Read and process as many packets as possible in read_udp_packets, to avoid ↵Steinar H. Gunderson
having to run the entire event loop once per packet. (Patch from the Google tree.)
2007-09-29There are two different places in write_tcp_data() that advance the ↵Steinar H. Gunderson
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.)
2007-09-28Forgot to include a few hunks from ares_process.c earlier. Fixing now.Steinar H. Gunderson
2007-09-28Support a few more socket options, and refactor the option setting a bit. ↵Steinar H. Gunderson
(Patch from the Google tree.)
2007-09-28Make the query callbacks return the number of timeouts that happened during ↵Steinar H. Gunderson
the execution of a query, and update documentation accordingly. (Patch from the Google tree.)
2007-09-28Three fixes in one commit (sorry): a) Take care of the tcpbuf if it ends ↵Steinar H. Gunderson
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.
2007-09-28Don't skip a server if it's the only one. (Bugfix from the Google tree.)Steinar H. Gunderson
2007-09-27wrong, revert the previous "fix" and instead check that the fd_set pointerDaniel Stenberg
is non-NULL before we FD_CLR
2007-09-27eek, fix the conditions to return on either problem instead of requiringDaniel Stenberg
both to occur
2007-09-22Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on inDaniel Stenberg
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.
2007-09-22Steinar H. Gunderson modified c-ares to now also do to DNS retries even whenDaniel Stenberg
TCP is used since there are several edge cases where it still makes sense.
2007-07-14Vlad Dinulescu fixed two outstanding valgrind reportsDaniel Stenberg
2007-06-02Brad House fixed VS2005 compiler warnings due to time_t being 64bit.Daniel Stenberg
He also made recent Microsoft compilers use _strdup() instead of strdup().
2007-05-30added ares_process_fd() to allow applications to ask for processing onDaniel Stenberg
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.
2007-02-26Removed inclusion of <sys/types.h> in .c-filesGisle Vanem
since it's already included through "setup.h".
2007-02-22Check for stdbool.h at configuration stage, and include it if available.Yang Tse
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
2007-02-16use macros ERRNO, SET_ERRNO(), SOCKERRNO and SET_SOCKERRNO() for errno handlingYang Tse
2007-02-04Use correct 3rd argument for ioctlsocket() under Watt-32.Gisle Vanem
2007-02-01compiler warning fixYang Tse
2006-10-25Compiler warning fixYang Tse
2006-10-18Check for USE_WINSOCK instead of WIN32 where the check was doneYang Tse
to verify winsock API availability.
2006-08-29Brad Spencer didDaniel Stenberg
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
2006-07-29Fix compiler warnings.Yang Tse
2006-07-28Replace send() and recv() with swrite() and sread() macros.Yang Tse
2006-07-222nd try adding CVS id.Gisle Vanem
2006-07-14Fix compiler warningYang Tse
2006-06-19Handle EAGAIN/EWOULDBLOCK readiness errors, which can occur for both TCP andWilliam Ahern
UDP even when a poll(2) or select(2) suggest otherwise.
2006-05-03Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makesDaniel Stenberg
c-ares call a callback on socket state changes. A better way than the ares_getsock() to get full control over the socket state.
2005-12-20Changes for PellesC for Win32. It needs <unistd.h> for 'ssize_t'. Hence theGisle Vanem
rearrangement in ares_process.c.
2005-12-09Fix compiler warningYang Tse
2005-11-25read_tcp_data() fix to get the proper buffer pointer and sizeDaniel Stenberg

2005-08-10make ares compile again for NetWare.Gunter Knauf
2005-06-03FIONBIO is in sys/ioctl.h on AIXDaniel Stenberg
2005-06-02sigh, define TRUE if not alreadyDaniel Stenberg
2005-06-02William Ahern:Daniel Stenberg
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.)
2005-04-06Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac OSDaniel Stenberg
