Daniel Stenberg 19c8da85d8 Fixed the problem where next_lookup would use 'status' uninitialized. Now
it gets passed the initial value as an argument.

Daniel Stenberg ccf083e26d ares_strerror() segfaulted if the input error number was out of the currently
supported range.
2007-10-01 22:52:31 +00:00

in as argument!

Steinar H. Gunderson c145fbea49 Fix a memory leak that I recently inadvertedly introduced. 2007-09-30 00:08:01 +00:00
Steinar H. Gunderson 84fcff79f4 Use ISDIGIT instead of isdigit; fixes a gcc warning. 2007-09-29 21:57:05 +00:00
Steinar H. Gunderson 2694b970e8 Port the TCP socket fix made in ares_fds() to ares_getsock() as well. 2007-09-29 19:26:59 +00:00
Steinar H. Gunderson 23f5d145ec 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.

Gisle Vanem b01ab65225 We should standarise on C comments. 2007-09-29 14:37:47 +00:00
Gisle Vanem 7a7f490efa Fix compiler warning in setsockopt(). 2007-09-29 14:34:59 +00:00
Steinar H. Gunderson 95c15fce0c TCP queries can time out too, not just UDP queries. (Patch from the Google tree.) 2007-09-29 14:25:14 +00:00
Steinar H. Gunderson c788efffd4 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.) 2007-09-29 14:21:47 +00:00
Steinar H. Gunderson c1a475e708 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.) 2007-09-29 14:09:14 +00:00
Steinar H. Gunderson d0de9663e2 Reject names that are longer than 255 characters, to avoid problems with strict or buggy DNS server implementations. (Patch from the Google tree) 2007-09-29 13:58:23 +00:00
Steinar H. Gunderson d6dd848523 In ares_mkquery, make sure we set buflen and buf to reasonable values if there's an error. (Patch from the Google tree) 2007-09-29 13:56:36 +00:00
Steinar H. Gunderson 9fc66e4dd9 Be stricter about what's a valid IP address in fake_hostent. (Patch from the Google tree.) 2007-09-29 13:52:14 +00:00
Steinar H. Gunderson 6ecea9453b Handle the root of the DNS tree correctly in ares_expand_name. 2007-09-29 13:38:17 +00:00
Daniel Stenberg 8179743cee today's modifications by Steinar and me 2007-09-28 20:28:20 +00:00
Daniel Stenberg 3d59a3855a Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI
and API changes in the progress callback (and possibly more coming up from
Steinar)
2007-09-28 20:28:06 +00:00
Steinar H. Gunderson ef3b425b11 Unrevert previous 'missing' hunks. They were missing since the patch is still in for review :-) 2007-09-28 15:56:28 +00:00
Steinar H. Gunderson 026d93b4f6 Yet more missing hunks... Nggh. 2007-09-28 15:55:11 +00:00
Steinar H. Gunderson 36710c4586 Always register for TCP events even if there are no outstanding queries, as the other side could always close the connection, which is a valid event which should be responded to. 2007-09-28 15:53:10 +00:00
Steinar H. Gunderson 63ac6156aa Forgot to include a few hunks from ares_process.c earlier. Fixing now. 2007-09-28 15:51:00 +00:00
Steinar H. Gunderson 08a70d117c Support a few more socket options, and refactor the option setting a bit. (Patch from the Google tree.) 2007-09-28 15:15:39 +00:00
Steinar H. Gunderson 6ce589c3ee 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.) 2007-09-28 14:46:51 +00:00
Steinar H. Gunderson d426c20c0a 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. 2007-09-28 14:28:14 +00:00
Steinar H. Gunderson 54ca7d8cb2 Don't skip a server if it's the only one. (Bugfix from the Google tree.) 2007-09-28 14:26:11 +00:00
Daniel Stenberg 015fc6aa17 wrong, revert the previous "fix" and instead check that the fd_set pointer
is non-NULL before we FD_CLR
2007-09-27 12:04:56 +00:00
Daniel Stenberg a739b9bc45 eek, fix the conditions to return on either problem instead of requiring
both to occur
2007-09-27 12:02:15 +00:00
Daniel Stenberg 0f4664d27f 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.
2007-09-22 21:23:10 +00:00
Daniel Stenberg 0f89a2e639 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.
2007-09-22 21:04:16 +00:00
Daniel Stenberg 05b26e7566 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.
