57d9eec6	2023-07-10T10:40:49	Disable signalfd by default signalfd may behave differently to sigaction/signal, so to avoid breaking libevent users (like [1], [2]) disable it by default. [1]: https://github.com/tmux/tmux/pull/3621 [2]: https://github.com/tmux/tmux/pull/3626 Also signalfd is not that perfect: - you need to SIG_BLOCK the signal before - blocked signals are not reset on exec - blocked signals are allowed to coalesce - so in case of multiple signals sent you may get the signal only once (ok for most of the signals, but may be a problem for SIGCHLD, though you may call waitpid() in a loop or use pidfd) - and also one implementation problem - sigprocmask is unspecified in a multithreaded process Refs: - https://lwn.net/Articles/415684/ - https://ldpreload.com/blog/signalfd-is-useless Refs: https://github.com/libevent/libevent/issues/1460 Refs: #1342 (cc @dmantipov)
83ef3216	2020-04-22T19:44:45	Add wepoll support to light up the epoll backend on Windows libevent is lacking a scalable backend on Windows. Let's leverage the wepoll library until Windows comes up with an epoll/kqueue compete user mode API. - All regress tests pass for standard wepoll - These 2 tests fail intermittently for changelist wepoll, so disabling changelist wepoll for now http/cancel_inactive_server http/stream_in - verify target on Windows runs tests for both wepoll and win32 backends - wepoll backend preferred over win32 backend - wepoll version 1.5.6 v2: cleaner backend abstraction. Disallow wepoll on MinGW/Cygwin. v3: Add wepoll.h to dist v4: Make sure wepoll source files are excluded from cygwin/mingw builds v5: Keep win32 as default backend on windows. v6: Include wepoll in mingw builds. Verified that regress tests pass w/ WEPOLL backend. v7: Enable wepoll on mingw when building with cmake v8: Add wepoll testrunner for autotools test target
8b0aa7b3	2017-09-14T17:39:20	Port `event_rpcgen.py` and `test/check-dumpevents.py` to Python 3. These scripts remain compatible with Python 2.

cf2cf2a0	2015-09-02T11:51:00	test: run regress with EVENT_DEBUG_MODE=1 and without This could show some bugs like "event_assign called on an already added event", and some others that debugging mode could track.
b1b69ac7	2014-01-17T23:20:42	Implemented EV_CLOSED event for epoll backend (EPOLLRDHUP). - Added new EV_CLOSED event - detects premature connection close by clients without the necessity of reading all the pending data. Does not depend on EV_READ and/or EV_WRITE. - Added new EV_FEATURE_EARLY_CLOSED feature for epoll. Must be supported for listening to EV_CLOSED event. - Added new regression test: test-closed.c - All regression tests passed (test/regress and test/test.sh) - strace output of test-closed using EV_CLOSED: socketpair(PF_LOCAL, SOCK_STREAM, 0, [6, 7]) = 0 sendto(6, "test string\0", 12, 0, NULL, 0) = 12 shutdown(6, SHUT_WR) = 0 epoll_ctl(3, EPOLL_CTL_ADD, 7, {EPOLLRDHUP, {u32=7, u64=7}}) = 0 epoll_wait(3, {{EPOLLRDHUP, {u32=7, u64=7}}}, 32, 3000) = 1 epoll_ctl(3, EPOLL_CTL_MOD, 7, {EPOLLRDHUP, {u32=7, u64=7}}) = 0 fstat(1, {st_mode=S_IFCHR\|0620, st_rdev=makedev(136, 4), ...}) mmap(NULL, 4096, PROT_READ\|PROT_WRITE, MAP_PRIVATE\|MAP_ANONYM... write(1, "closed_cb: detected connection close "..., 45) = 45

26c75828	2012-04-26T16:22:03	When PRECISE_TIMERS is set with epoll, use timerfd for microsecond precision The epoll interface ordinarily gives us one-millisecond precision, so on Linux it makes perfect sense to use the CLOCK_MONOTONIC_COARSE timer. But when the user has set the new PRECISE_TIMER flag for an event_base (either by the EVENT_BASE_FLAG_PRECISE_TIMER flag, or by the EVENT_PRECISE_TIMER environment variable), they presumably want finer granularity. On not-too-old Linuxes, we can achieve this using the Timerfd mechanism, which accepts nanosecond granularity and understands posix clocks. It's a little more expensive than just calling epoll_wait(), so we won't do it by default.
9b856fd5	2012-04-07T17:32:00	Simplify test.sh code significantly. Also make it easier to add new tests/backends.

7afe48aa	2012-03-23T17:56:23	Add a unit test for event_base_dump_events() This function uses a C program to generate its output, and then uses a Python program to check it for correctness. On systems without Python, we just make sure that the C program doesn't crash. It's likely that we should be requiring some particular python version. This is an alpha, though: I'm sure somebody will tell us which.
2ef92786	2012-02-23T21:40:02	Add a new test: test-fdleak which tests for fd leaks by creating many sockets. This test opens a server socket, and forks a child which connects to that server socket many times. It sets a low number for the max open file limit to catch any file descriptor leaks. It would not work on Windows since it uses fork() to be able to create both the server and the clients.

7c926916	2010-07-19T15:14:10	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.
3689bd2d	2010-05-26T13:32:32	Have the unit tests report errors from test.sh The default behavior of test.sh was to suppress all output from test/regress, and say nothing but OKAY or FAILED. This wasn't so good for getting bugs reported, since lots of people didn't know to set TEST_OUTPUT_FILE, or re-run ./test/regress on its own. Now, when you don't specify an output file for test.sh, it runs regress with the --quiet option. This option makes the unit tests only print output on failure, which is what we probably wanted.
faf2a04f	2010-05-26T13:31:41	Make test.sh exit with nonzero status if tests fail This behavior makes "make verify" actually fail when the tests fail, which is what it's supposed to do.
3d9e05b1	2010-05-08T19:56:25	Fix test.sh on freebsd It turns out that in all conformant shells, "unset FOO" removes FOO both from the shell's variables and from the exported environment. (I've tested this on msys, opensolaris, linux, osx, and freebsd.) And in nearly every shell I can find, "unset FOO; export FOO" does the same as unset FOO... except in my FreeBSD VM, where the "export FOO" sets the exported value of FOO equal to "". This broke test.sh for us. The fix is simple: remove the needless exports!
0ee6f6ce	2010-05-08T18:00:26	Make test.sh support mingw/msys on win32 This required: - Adding another WIN32 section in test.sh - not running "touch /dev/null" - calling WSAStartup in all the test binaries - Fixing a dumb windows-only bug in test-time.c
94131e92	2010-01-12T15:58:36	Fix test.sh on shells without echo -n Some systems have a version of /bin/sh whose builtin echo doesn't support the -n option used in test/test.sh. /bin/echo, however, usually does. This patch makes us use /bin/echo for echo -n whenever it is present. Also, our use of echo -n really only made sense when suppressing all test output. Since test output isn't suppressed when logging to a file, this pach makes us stop using echo -n when logging to a file.
