499452f4 2010-08-28 02:44:11 IOCP-related unit test tweaks
76f7e7ae 2010-08-17 05:02:00 Some IOCP bufferevent tweaks. - Increment reference count of bufferevents before initiating overlapped operations to prevent the destructor from being called while operations are pending. The only portable way of canceling overlapped ops is to close the socket. - Translate error codes to WSA* codes. - Better handling of errors. - Add an interface to add and del "virtual" events. Because IOCP bufferevents don't register any events with the base, the event loop has no way of knowing they exist. This causes the loop to terminate prematurely. event_base_{add,del}_virtual increment/decrement base's event count so the loop runs while there are any enabled IOCP bufferevents.
d844242f 2010-08-28 02:08:27 Stop IOCP when freeing the event_base.
03afa209 2010-08-16 01:23:57 IOCP-related evbuffer fixes. - Prevent evbuffer_{add,prepend}_buffer from moving read-pinned chains. - Fix evbuffer_drain to handle read-pinned chains better. - Raise the limit on WSABUFs from two to MAX_WSABUFS for overlapped reads.
42090072 2010-09-06 15:47:07 Move the "function to getsockname() on a listener" to regress_testutils This reverts commit fab50488fcb741884ccdfa7b83643eac3e5c9cbf. The function was, on reflection, not important enough to break the feature freeze, since it's trivial to build on your own.

a97320ac 2010-09-03 18:48:31 Allow more than one copy of regression tests to run at once Mostly this was a matter of just removing all the hardwired ports in the test code. The http/connection_retry test is still a little screwy, though.

e50c0fcc 2010-09-02 11:10:50 Use the _func() replacements for open, fstat, etc in evutil.c on win32 Remember that in a fit of ANSI C compliance, Microsoft decided to screw portability by renaming basically all the functions in unistd.h to get prefixed with an understore. For some reason, mingw didn't seem to mind, but at least some people's compilers did: see bug 3044490.
f0056d04 2010-09-02 12:06:58 Declare signal handler function as "__cdecl" on Windows. I swear, they must have half a dozen different calling conventions. (goes to check) Holy crud. They actually do. There's __cdecl, __stdcall, __fastcall, "thiscall", "naked" and the obsolete "__pascal", "__fortran", and "__syscall". And don't forget WINAPI and __far. Anyways, this should fix 3044488 if I got it right.
ca9048f1 2010-09-02 11:36:44 Move evkeyvalq into a separate header for evhttp_parse_query users The evhttp_parse_query API is a bit misdesigned; all the other evkeyvalq stuff is abstract and lets you get away with having a header stub, but evhttp_parse_query seems to require that you instantiate an empty evkeyvalq of your own.
d3ceca80 2010-09-02 11:27:57 Declare evkeyvalq and event_list even if event_struct.h comes before sys/queue.h Fixes bug 3036645 reported by Mihai Draghicioiu
acc4aca4 2010-08-30 11:35:06 Fix a bug in our win32 condition implementation The do ... while loop in our wait code could spin while waiting because the event object wasn't reset until there were no longer any events waiting to be woken up. We also want to reset the event object if the count of events to wake up reaches zero. Found by Chris Davis. Fixes bug 3053358.
d61b2f33 2010-08-26 15:09:58 Fix an issue with forking and signal socketpairs in select/poll backends Nicholas Marriott identifies an issue where a signal socketpair doesn't get recreated if the event backend doesn't set event_reinit. See bug 3048812 There may be a similar issue with respect to th_notify_fd

da6e7cd4 2010-08-17 13:26:03 Correctly detect failure to delete bufferevent read-timeout event Gilad Benjamini noted that we check the error code for deleting a write-timeout event twice, and the read timeout not at all. This shouldn't be a bit problem, since it's really hard for a delete to fail on a timeout-only event, but it's worth fixing. Fixes bug 3046787
5fb10958 2010-08-16 22:55:45 Add a unit test for conditions
d74ae381 2010-08-16 12:38:22 Make the regress_pthread.c tests work on windows with current test APIs
e0972c21 2010-08-17 13:18:18 Use conditions instead of current_event_lock to fix a deadlock. Avi Bab correctly noted as bug 3044479 the fact that any thread blocking on current_event_lock will do so while holding th_base_lock, making it impossible for the currently running event's callback to call any other functions that require th_base_lock. This patch switches the current_event_lock code to instead use a condition variable that we wait on if we're trying to mess with a currently-executing event, and that we signal when we're done executing a callback if anybody is waiting on it.
d4977b52 2010-08-17 13:15:34 Add a condition variable backend, with implementations for pthreads and win32 The interface from the user's POV is similar to the locking implementation: either provide a structure full of function pointers, or just call evthread_use_*_threads() and everything will be okay. The internal interface is meant to vaguely resemble pthread_cond_*, which Windows people will better recognize as *ConditionVariable*.
39201728 2010-08-13 17:19:18 Make definition of WIN32_LEAN_AND_MEAN in event.h conditional. (Inclusion order might trigger a warning for redefinition on Windows.)
60433a0a 2010-08-13 17:08:59 Clean up syntax on TAILQ_ENTRY() usage Though the C standards allow it, it's apparently possible to get MSVC upset by saying "struct { int field; } (declarator);" instead of "struct {int field; } declarator;", so let's just not do that. Bugfix for 3044492 (commit msg by nickm)
a4af9be1 2010-08-13 11:41:37 Make include/event2/event-config.h not included in source dist As a generated file, it shouldn't get included in our source distribution. Apparently there is an automake incant for this: nobase_ even stacks with nodist_ .
4022b287 2010-08-13 11:34:39 Change include order in Makefile.nmake If there is an event-config.h in include/event2 (either because we screwed up packaging like in 2.0.6-rc or because we previously tried building with mingw and we didn't make distclean in the middle), we want MSVC to find the one one in WIN32-Code/include/event2 first. Found by Gilad Benjamini.

0bffe43a 2010-08-09 12:08:40 Fix a nasty dangling-event bug when using rate-limiting groups When we freed a bufferevent that was in a rate-limiting group and blocked on IO, the process of freeing it caused it to get removed from the group. But removing the bufferevent from the group made its limits get removed, which could make it get un-suspended and in turn cause its events to get re-added. Since we would then immediately _free_ the events, this would result in dangling pointers. Fixes bug 3041007.

28f31a4f 2010-08-06 16:36:23 Fix unit tests with -DUSE_DEBUG enabled If you were to enable USE_DEBUG and slog through all 700+ MB of debugging output, you'd find that one of the unit tests failed, since it tested the debug logging code, but the string it expected and the string it logged differed by a tab vs 2 spaces.

9b602096 2010-08-06 13:03:17 Use AF_INET socketpair to test sendfile on Solaris
57b30cd7 2010-08-06 13:01:32 Turn our socketpair() replacement into its own function This patch splits the formerly windows-only case of evutil_socketpair() into an (internal-use-only) function named evutil_ersatz_socketpair(), and makes it build and work right on non-Windows hosts. We need this for convenience to test sendfile on solaris, where socketpair can't give you an AF_INET pair, and sendfile() won't work on AF_UNIX.

b2c6202d 2010-08-04 15:52:32 Fix an assertion bug in test-ratelim If the rate limit was low enough, then the echo_conns wouldn't finish inside the 300 msec we allowed for them to close. Instead, count the number of connections we have, and keep waiting until they are all closed.
42f6b624 2010-08-04 15:51:14 Add option to test-ratelim to test min_share
6ae53d67 2010-08-04 15:44:08 Add an interface to expose min_share in ratelimiting groups
009f3005 2010-08-04 14:54:38 Fix rate-limit calculation on openssl bufferevents. When you're doing rate limiting on an openssl connection, you nearly always want to limit the number of bytes sent and received over the wire, not the number of bytes read or written over the secure transport.
13b912e4 2010-08-01 21:39:48 Fixed compilation of sample/le-proxy.c on win32
42a8c711 2010-07-31 17:10:04 Build more cleanly with NetBSDs that dislike toupper(char) To be fair, when char can be signed, if toupper doesn't take negative characters, toupper(char) is a very bad idea. So let's just use the nice safe EVUTIL_TOUPPER instead. (It explicitly only upcases ASCII, but we only use it for identifiers that we know to be ASCII anyway).
840a72fb 2010-07-29 20:32:40 Fix badly-behaved subtest of dns/bufferevent_connect_hostname The bufferevent_connect_hostname test was specifying AF_INET, but the gethostbyname test we were using to see what error to expect was using PF_UNSPEC, leading to possible divergence of results.

7e87a599 2010-07-21 14:33:42 Stop asserting when asked for a (unsupported) TCP dns port. Just return NULL.
c9913174 2010-07-19 15:31:19 Change bufferevent_openssl::do_write so it doesn't call SSL_write with a 0 length buffer I was running into a problem when using bufferevent_openssl with a very simple echo server. My server simply bufferevent_read_buffer 'd data into an evbuffer and then passed that evbuffer straight to bufferevent_write_buffer. The problem was every now and again the write would fail for no apparent reason. I tracked it down to SSL_write being called with the amount of data to send being 0. This patch alters do_write in bufferevent_openssl so that it skips io_vecs with 0 length.
7c926916 2010-07-19 15:14:10 Make test/test.sh call test-changelist Eventually test-changelist should expand to try more cases, maybe query the status of the actual changelist somehow, and integrate it with the rest of the unit tests. Also, add test-changelist to gitignore.

b00d4c04 2010-07-19 14:58:08 Remove unused variables in test/test-changelist.c
cf249e7d 2010-07-19 13:44:56 Possible fix to 100% cpu usage with epoll and openssl I'm running a fairly simple bit of test code using libevent2 with epoll and openssl bufferevents and I've run into a 100% cpu usage problem. Looking into it 100% usage was caused by epoll_wait constantly returning write events on the openssl socket when it shouldn't really have been looking for write events at all (N_ACTIVE_CALLBACKS() was returning 0 also). Looking a bit deeper eventbuffer_openssl socket seems to be requesting that the EV_WRITE event be removed when it should, but the event isn't actually being removed from epoll. Continuing to follow this I think I've found a bug in event_changelist_del. For evpoll event_del calls event_changelist_del which caches the change which is then actioned later when evpoll_dispatch is called. In event_changlist_del there is a check so that if the currently changed action is an add then the cached action is changed to a no-op rather than a delete (which makes sense). The problem arises if there are more than two add or delete operations between calls to dispatch, in this case it's possible that the delete is turned into a no-op when it shouldn't have been. For example starting with the event on, a delete followed by an add and then another delete results in a no-op when it should have been a delete (I added a fair bit of debug output that seems to confirm this behaviour). I've applied a small change that checks the original old_event stored with the change and only converts the delete to a no-op if the event isn't on in old_event. This seems to have fixed my problem.
928b7d49 2010-07-16 12:38:23 Merge branch 'pncalls_fix'
65abdc20 2010-07-16 09:11:09 Fix wrong sie calculation of iovec buffers when exact=1 The old code had a bug where the 'exact' flag to 1 in _evbuffer_read_setup_vecs would never actually make the iov_len field of the last iovec get truncated. This patch fixes that.
7c2dea16 2010-07-13 11:06:08 Pass flags to fcntl(F_SETFL) and fcntl(F_SETFD) as int, not long Everybody but Linux documents this as taking an int, and Linux is very tolerant of getting an int instead. If it weren't, everybody doing fcntl(fd,F_SETFL,O_NONBLOCK) would break, since the glibc headers define O_NONBLOCK as an int literal.
e73cbde1 2010-07-08 14:41:02 Suppress a spurious EPERM warning in epoll.c It's okay for us to get an EPERM when doing an EPOLL_DEL on an fd; it just means that before we got a chance to the EPOLL_DEL, we closed the fd and reopened a new non-socket that wound up having the same fd. Partial fix for Bug 3019973.
fc5e0a23 2010-07-05 14:39:39 Don't race when calling event_active/event_add on a running signal event There was previously no lock protecting the signal event's ev_ncalls/ev_pncalls fields, which were accessed by all of event_signal_closure, event_add_internal, event_del_internal, and event_active_nolock. This patch fixes this race by using the current_event_lock in the same way it's used to prevent event_del_internal from touching an event that's currently running.
61e1eeec 2010-07-05 13:24:45 Tidy up the code in evthread_make_base_notifiable a little Previously, we had a few conditional statements with the "if (...)" inside an #ifdef and the body outside. That kind of thing is hard to read.
a5bc15b2 2010-07-05 13:24:12 Drain th_notify_fd[0] more bytes at a time.
17522d2a 2010-07-05 13:17:47 Fix a deadlock related to event-base notification. Diagnosed by Zhou Li, Avi Bab, and Scott Lamb. The problem was that the thread doing the notification could block on write in evthread_notify_base_default while holding the th_base_lock. The main thread would never drain th_notify_fd[0], since it would need th_base_lock to actually trigger events.
d89fdba4 2010-07-05 12:28:22 Make sample/hello_world work on windows We forgot to include the WSAStartup call in main(). Patch from an anonymous user on Sourceforge. Fixes bug 3025354.

14250031 2010-06-23 01:15:15 Really only add libevent_core.la to LIBADD on mingw Commit fdc629736e1 tried to do this, but added it for mingw and for everything else. Fixes a segfault in bufferevent unittests.
215e629c 2010-06-21 12:26:21 Add bufferevent_lock()/bufferevent_unlock() Although bufferevent operations are threadsafe, sometimes you need to make sure that a few operations on a single bufferevent will all be executed with nothing intervening. That's what these functions are for.

44d57eee 2010-06-03 11:25:54 Add test for behavior on remote socket close On all the backends on this little mac laptop, that behavior is to report a remote socket close as both EV_READ and EV_WRITE. Historically, we had problem for some of these behaviors on some backends, so let's make sure that such behaviors don't come back.
3467f2fa 2010-05-28 15:05:32 Fix logic in correcting high values from FIONREAD The old logic made sense back when buffer.c was an enormous linear buffer, but it doesn't make any sense for the chain-based implementation. This patch also refactors the ioctl{socket}? call into its own function.
0798dd12 2010-05-27 22:37:09 Close the file in evutil_read_file whether there's an error or not. evutil_read_file would close the file if there was an error, but not if things went normally.
