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.

Daniel Stenberg e5247ae65d Added ares_getsock() to extract sockets to wait for action on, without being
limited to select().
