2007-10-04Another timeout fix in ares_getnameinfo().Steinar H. Gunderson
2007-10-04Send the timeout count in ares_getnameinfo().Steinar H. Gunderson
2007-10-04Moved the NULL check for channel upwards in ares_destroy().Steinar H. Gunderson
2007-10-04Clarified the comment over ares_cancel.Steinar H. Gunderson
2007-10-02Avoid a segfault when generating a DNS "Transaction ID" in internalYang Tse
function init_id_key() under low memory conditions.
2007-10-02Add ares_llist.c and ares_llist.h to MSCV project file.Yang Tse
2007-10-02Fixed the problem where next_lookup would use 'status' uninitialized. NowDaniel Stenberg
it gets passed the initial value as an argument.
2007-10-02Avoid inline C99ism, and move c-ares routines for managing doubly-linked lists.Yang Tse
2007-10-01ares_strerror() segfaulted if the input error number was out of the currentlyDaniel Stenberg
supported range.
2007-10-01Prevent ares_strerror() from segfaulting if an invalid error code is passedDaniel Stenberg
in as argument!
2007-09-30Fix compiler warningYang Tse
2007-09-30check availability of <netinet/tcp.h>Yang Tse
2007-09-30improve portability, defining MAXDNAME and MAXCDNAMEYang Tse
2007-09-30Fix a memory leak that I recently inadvertedly introduced.Steinar H. Gunderson
2007-09-29Use ISDIGIT instead of isdigit; fixes a gcc warning.Steinar H. Gunderson
2007-09-29Port the TCP socket fix made in ares_fds() to ares_getsock() as well.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.
2007-09-29We should standarise on C comments.Gisle Vanem
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.)
2007-09-29Reject names that are longer than 255 characters, to avoid problems with ↵Steinar H. Gunderson
strict or buggy DNS server implementations. (Patch from the Google tree)
2007-09-29In ares_mkquery, make sure we set buflen and buf to reasonable values if ↵Steinar H. Gunderson
there's an error. (Patch from the Google tree)
2007-09-29Be stricter about what's a valid IP address in fake_hostent. (Patch from the ↵Steinar H. Gunderson
Google tree.)
2007-09-29Handle the root of the DNS tree correctly in ares_expand_name.Steinar H. Gunderson
2007-09-28today's modifications by Steinar and meDaniel Stenberg
2007-09-28Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABIDaniel Stenberg
and API changes in the progress callback (and possibly more coming up from Steinar)
2007-09-28Unrevert previous 'missing' hunks. They were missing since the patch is ↵Steinar H. Gunderson
still in for review :-)
2007-09-28Yet more missing hunks... Nggh.Steinar H. Gunderson
2007-09-28Always register for TCP events even if there are no outstanding queries, as ↵Steinar H. Gunderson
the other side could always close the connection, which is a valid event which should be responded to.
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.
2007-09-22Brad House provided a fix for ares_save_options(): Apparently I overlookedDaniel Stenberg
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.
