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.
2007-09-28Make 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.

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.
2004-07-22- Fixed a few variable return types for some system calls. Made configureDaniel Stenberg
check for ssize_t to make it possible to use that when receiving the send() error code. This is necessary to prevent compiler warnings on some systems. - Made configure create config.h, and all source files now include setup.h that might include the proper config.h (or a handicrafted alternative). - Switched to 'ares_socket_t' type for sockets in ares, since Windows don't use 'int' for that. - automake-ified and libool-ified c-ares. Now it builds libcares as a shared lib on most platforms if wanted. (This bloated the size of the release archive with another 200K!) - Makefile.am now uses Makefile.inc for the c sources, h headers and man pages, to make it easier for other makefiles to use the exact same set of files. - Adjusted 'maketgz' to use the new automake magic when building distribution archives.
