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.

TCP queries can time out too, not just UDP queries. (Patch from the Google tree.)

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.)

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.)

Unrevert previous 'missing' hunks. They were missing since the patch is still in for review :-)

Yet more missing hunks... Nggh.

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.

Forgot to include a few hunks from ares_process.c earlier. Fixing now.

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.)

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.

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.

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.

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.

2007-07-04 17:20:19 +00:00
76a007538c
although the check for HAVE_STRUCT_TIMEVAL solved the redefine it is incorrect; lets see if a check for HAVE_GETTIMEOFDAY also works; if gettimeofday() is present then we can assume we have the timezone struct too.
