5b4b8126	2012-02-06 12:24:49	Loop on filtering SSL reads until we are blocked or exhausted. This is not a perfect fix, but it's much much better than the current buggy behavior, which could lead to filtering SSL connections that just stopped reading. Based on ideas by Maseeb Abdul Qadir and Mark Ellzey.
d84d9170	2011-11-21 09:41:55	Use C-style comments in C source files (for compatibility with compilers such as xlc on AIX).
d6094b16	2012-02-01 14:56:43	evdns: fix a bug in circular-queue implementation found by Wang Qin
9f9e259f	2012-01-26 15:04:24	Better workaround for Linux 3.2 edge-triggered epoll bug On further investigation, it appears that this problem is limited to AF_UNIX sockets, so let's just do the test on AF_INET sockets.
c94a5f2a	2012-01-24 17:15:50	Do a memberwise comparison of threading function tables Doing a memcmp risks comparing uninitialized padding bytes at the end of the structure.

5408ff3b	2012-01-24 11:16:26	Oops:remove an accidentally committed "sleep(1)" in a unit test
dab91877	2012-01-24 11:04:19	Workaround in the unit tests for an apparent epoll bug in Linux 3.2
3f18ad1b	2012-01-23 18:15:44	Fix a fd leak in event_reinit() We were supposed to be closing the ev_signal_pair sockets.
6e41cdc1	2012-01-23 17:59:16	Fix a list corruption bug when using event_reinit() with signals present While re-adding all the events, event_reinit() could add a signal event, which could then cause evsig_add() to add the base->sig.ev_signal event. Later on its merry path through base->eventqueue, event_reinit() would find that same event and give it to event_io_add a second time. This would make the ev_io_next list for that fd become circular. Ouch!
3312b020	2012-01-23 17:43:35	Check event_base correctness at end of each unit test
27737d55	2012-01-21 12:55:15	Add function to check referential integrity of an event_base
790f6b3b	2012-01-10 18:33:58	Force strict validation of HTTP version in response. This sometimes accepted invalid versions like 'ICY' (n = 0, major = undefined, sometimes > 1).
7206e8cd	2012-01-16 14:45:31	Suppress a gcc warning from ignoring fwrite return in http-sample.c Found by Steve Snyder
cba48c7d	2012-01-09 16:44:53	Fix a race condition in the dns/bufferevent_connect_hostname test. As originally written, the test would only pass if the accept() callbacks for the evconnlistener were all invoked before the last of the CONNECTED/ERROR callbacks for the connecting/resolving bufferevent had its call to event_base_loopexit() complete. But this was only accidentally true in 2.0, and might not be true at all in 2.1 where we schedule event_base_once() callbacks more aggressively. Found by Sebastian Hahn.
ecfc720a	2012-01-09 11:49:41	Make evconnlistener work around bug in older Linux when getting nmapped Older Linuxes sometimes respond to some nmap probes by having accept() return a success but with socklen 0. That can lead to confusing behavior when you go to process the sockaddr.
f0325167	2012-01-09 11:33:38	Remove bogus casts of socket to int before calling ev_callback This should make 64-bit windows act better. Found by Mark Heily.
da70fa70	2011-12-14 16:17:19	Backport evhttp_connection_get_bufferevent to Libevent 2.0 Backport by Arno Bakker; original implementation in 8d3a8500f4

c986f232	2011-12-08 14:30:20	Fix behavior of evbuffer_peek(buf,-1,NULL,NULL,0) (Patch altered by nickm to not affect the behavior of evbuffer_peek(buf,-1,NULL,vec,n_vec).)
358c745e	2011-12-08 11:39:48	check for sysctl before we use it Not all C libraries under Linux support the sysctl() func.
19277763	2011-12-06 13:35:54	Fix a silly compilation error with the sun compiler Apparently, other compilers were allowing "return free(x)" in a function returning void.
11f36a5f	2011-12-05 15:02:27	Be absolutely sure to clear pncalls before leaving event_signal_closure I thought we'd fixed the cases where this could come up, but apparently having an event_base_break() happen while processing signal events could get us in trouble. Found by Remi Gacogne. Sourceforge issue 3451433 .

2aa036fa	2011-11-17 11:59:41	Avoid spinning on OpenSSL reads Previously, if some sender were generating data to read on an OpenSSL connection as fast as we could process it, we could easily wind up looping on an openssl do_read operation without ever considering other sockets. The difference between this and the original method in consider_reading() is that it only loops for a single completed frame instead of looping until fd is drained or an error condition was triggered. {Patch split out by nickm}
96c562fa	2011-11-17 11:54:07	Move SSL rate-limit enforcement into bytes_to_read()
a186e732	2011-11-17 11:45:49	Refactor amount-to-read calculations in buffervent_ssl consider_reading() Split up consider_reading()'s conditional checks into another function can_read() for simplicity sake. {Split into a separate patch by nickm}
6660c9a3	2011-11-15 18:34:24	Revert "Avoid potential SSL read spinlocks" This reverts commit fc52dbac87f4937f8306759506d6a2ad15ca244c.
a62346de	2011-11-15 18:33:50	Revert "openssl bufferevent has the same issue with writing as prior commit." This reverts commit 7353663eb7c0b2a1caaaa5acd818515f156cf2ca.

7353663e	2011-11-14 10:57:15	openssl bufferevent has the same issue with writing as prior commit.
fc52dbac	2011-11-14 10:24:07	Avoid potential SSL read spinlocks OpenSSL bufferevents with deferred callbacks enabled under high load will spinlock in the function consider_reading(). This loop continues until all data has been read. Because of this condition; openssl bufferevents will never return back into event_base_loop() until SSL_read has determined data is no longer ready. As of yet I have not found a reason why this while loop exists, so this patch just swaps out while for if. If needed I can write same code which would trigger this effect; optionally libevhtp has a test.c program which can be run with the following flags: ./test -s <keyfile.pem> curl -vvvv -k -d@<HUGE_ASS_FILE> https://127.0.0.1:8081/ The return data will include the number of times the readcb got data and the length of that read. Without this patch, you are likely to see a small amount of "bytes read....", otherwise the "bytes read..." return data should show much more reasonable numbers.

21a08d68	2011-10-19 22:38:37	Empty DNS reply with OK status is another way to say NODATA. Sometimes DNS reply has nothing but query section. It does not look like error, so it should be treated as NODATA with TTL=0 as soon as there is no SOA record to deduce negative TTL from.

0ba0af9c	2011-09-29 09:30:04	Prefer mmap to sendfile unless a DRAINS_TO_FD flag is set. Allows add_file to work with SSL. The sendfile() implementation for evbuffer_add_file is potentially more efficient, but it has a problem: you can only use it to send bytes over a socket using sendfile(). If you are writing bytes via SSL_send() or via a filter, or if you need to be able to inspect your buffer, it doesn't work. As an easy fix, this patch disables the sendfile-based implementation of evbuffer_add_file on an evbuffer unless the user sets a new EVBUFFER_FLAG_DRAINS_TO_FD flag on that evbuffer, indicating that the evbuffer will not be inspected, but only written out via evbuffer_write(), evbuffer_write_atmost(), or drained with stuff like evbuffer_drain() or evbuffer_add_buffer(). This flag is off by default, except for evbuffers used for output on bufferevent_socket. In the future, it could be interesting to make a best-effort file segment implementation that tries to send via sendfile, but mmaps on demand. That's too much complexity for a stable release series, though.

0ff2c5a9	2011-08-24 18:42:12	Have test-ratelim.c support IOCP
a98da7bf	2011-08-24 18:41:35	Make IOCP rate-limiting group support stricter and less surprising. Previously, we wouldn't decrement read/write buckets because of IOCP reads and writes until those reads and writes were complete. That's not so bad on the per-connection front. But for group limits, the old approach makes us launch a huge amount of reads and writes whenever the group limit becomes positive, and then decrement the limit to a hugely negative number as they complete. With this patch, we decrement our read buckets whenever we launch an IOCP read or write, based on the maximum that tried to read or write. Later, when the operations finish, we re-increment the bucket based on the portion of the request that couldn't finish.

643922e9	2011-08-15 13:39:10	Solaris sendfile: correctly detect amount of data sent Original message: Solaris sendfile seems to fail when sending moderately large (<1GB) files. Not a 32/64 problem, but a buffer problem. Anyone else ever try this? It is definitely broken in http-server.c. It seems to be broken in the following way: When sendfile sends partial data (EAGAIN, would block), "res" is always -1, rather than the amount sent. Here's a patch that reads from the "offset" pointer instead to discover what was sent. This seems to work:

6d5440e8	2011-08-11 15:15:17	Fix handling of group rate limits under 64 bytes of burst The "min_share" logic, which was designed to prevent piles of extremely small writes when running up against a group rate limit, could lead to confusing behavior if you ever set a min_share less than your burst rate. If that happened, then as soon as your group rate limit was exhausted, you'd stop reading/writing, and never start again, since the amount readable/writeable would never actually hit min_share. We now cap min_share at the rate per tick. Found by George Kadianakis
5d1b255b	2011-08-10 19:11:55	Ignore deprecation warnings on OS X Starting with Lion, Apple decided to deprecate the system openssl. We can start requiring users to install their own openssl once OS X doesn't ship with it anymore.
