Hennadii Stepanov 1759485e 2024-12-20T15:56:10 Improve portability on NetBSD According to GCC documentation, "the various `-std` options disable certain keywords". This change adheres to GCC's recommendation by replacing the `typeof` keyword with its alternative, `__typeof__`.
Andy Pan 528fbed1 2024-05-19T17:42:19 kqueue: make changelist and eventlist of kevent share the same array The array used by the changelist of the kevent() can be reused by the eventlist, We should make use of this feature to eliminate the extra overhead of array allocation. https://man.freebsd.org/cgi/man.cgi?kqueue https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man2/kqueue.2.html https://leaf.dragonflybsd.org/cgi/web-man?command=kqueue&section=2 https://man.netbsd.org/kqueue.2 https://man.openbsd.org/kqueue.2 --------- Signed-off-by: Andy Pan <i@andypan.me>
Andy Pan aef201a9 2024-04-29T13:35:33 Change ident for EVFILT_USER to 0 and add a test (#1582) Conventionally, ident for EVFILT_USER is set to 0 to avoid collision of file descriptors, which is what other renowned networking frameworks like netty(java), mio(rust), gnet(go), swift-nio(swift), etc. do currently.

Kamil Rytarowski 72e6eff0 2019-10-04T01:26:47 Fix compat with NetBSD >= 10 kevent::udata was switched from intptr_t to void*. Handle both cases with the GCC extension typeof().
Tobias Stoeckmann 2707a4ff 2019-05-10T23:54:14 kqueue: Avoid undefined behaviour. As ploxiln pointed out in pull request 811 the check "newsize < 0" is undefined behaviour (signed int overflow). Follow the advice and check kqop->changes_size instead. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org> Closes: #813 (cherry-picked)
Tobias Stoeckmann cf8acae3 2019-05-07T20:53:17 Prevent integer overflow in kq_build_changes_list. On amd64 systems with kqueue (e.g. *BSD systems) an integer overflow could be triggered with an excessively huge amount of events. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
Mark Mentovai df6f99e5 2016-07-08T09:43:39 Check for Mac OS X 10.4 kqueue bug properly EV_ERROR is a bit in struct kevent::flags. Other bits may be set too. Actually we have osx builds on travis-ci, but it uses osx 10.9.5, and we don't have warnings there, since I guess that there is no OR'ing with previous flag in case of error, while in 10.12 there is OR. Fixes: #377 Fixes: #376 Link: https://crbug.com/626534 Link: https://travis-ci.org/libevent/libevent/jobs/141033429
Ed Schouten 5602e451 2015-08-25T23:31:07 Assume that ke_udata is an integer type on CloudABI.
Ed Schouten 193c7de5 2015-08-25T15:32:25 Remove BSD-ism: TIMEVAL_TO_TIMESPEC(). Systems like CloudABI implement kqueue() but do not provide the BSD-specific TIMEVAL_TO_TIMESPEC() macro. Change the code to perform this manually, as it is not hard to do this conversion.
Adrian Chadd 6fd73944 2014-06-07T12:57:02 Handle ENOTCAPABLE from FreeBSD - this is returned if an event in the changelist is for an FD that has been closed.
Nick Mathewson 53a07fe2 2010-09-17T00:34:13 Replace pipe-based notification with EVFILT_USER where possible Sufficiently recent kqueue implementations have an EVFILT_USER filter that we can use to wake up an event base from another thread. When it's supported, we now use this mechanism rather than our old (pipe-based) mechanism. This should save some time and complications on newer OSX and freebsds.

Nick Mathewson 8ac3c4c2 2012-02-29T15:07:33 Have all visible internal function names end with an underscore. We haven't had a convention for naming internal functions in -internal.h versus naming visible functions in include/**.h. This patch changes every function declared in a -internal.h file to be named ending with an underscore. Static function names are unaffected, since there's no risk of calling them from outside Libevent. This is an automatic conversion.

Nick Mathewson 68120d9b 2012-02-29T15:07:31 Convert event-config.h macros to avoid reserved identifiers C reserves all identifiers beginning with an underscore for system use. But we had been mangling our autoconf identifiers with the prefix "_EVENT_" to avoid conflict with other programs. Instead, we will now use the prefix "EVENT__". With any luck, the double-underscore will still hint "here be dragons" to anybody tempted to think that event-config.h is a stable api. This is an automatically generated patch. The script that produced it was made by running this script over config.h.in: ===== #!/usr/bin/perl -w # Run this on config.h.in use strict; my %macros = (); while (<>) { if (/^# *undef +([A-Za-z0-9_]+)/) { $macros{$1} = 1; } } print "#!/usr/bin/perl -w -i -p\n\n"; for my $k (sort keys %macros) { print "s/(?<![A-Za-z0-9_])_EVENT_$k(?![A-Za-z0-9_])/EVENT__$k/g;\n"; } == And the script that it generated was then run over all .c and .h files: #!/usr/bin/perl -w -i -p s/(?<![A-Za-z0-9_])_EVENT_DISABLE_DEBUG_MODE(?![A-Za-z0-9_])/EVENT__DISABLE_DEBUG_MODE/g;

Nick Mathewson 5d7bfa15 2012-02-10T11:24:51 In the kqueue backend, do not report EBADF as an EV_READ We were doing this because of (correct) reports that NetBSD gives an EBADF when you try to add the write side of a pipe for which the read side has been closed. But on most kqueue platforms, that doesn't happen, and on *all* kqueue platforms, reporting a nonexistent fd (which we usually have if we have seen EBADF) as readable tends to give programs a case of the vapors. Nicholas Marriott wrote the original patch here; I did the comment fixes.

Nick Mathewson 1fd34ab4 2011-06-08T14:56:19 Report kqueue ebadf, epipe, and eperm as EV_READ events When asked to add one side of a pipe, and the other side has been closed, kqueue on NetBSD will say EBADF; kqueue on FreeBSD will say EPIPE, and kqueue on OpenBSD will say EPERM. So treat all of these as EV_READ events, to give the user an opportunity to notice that the pipe is closed. Diagnosed by Nicholas Marriott and Dale Rahn; based on a patch by Nicholas Marriott.

Nick Mathewson 28317a08 2011-05-03T13:54:57 Fix a warn-and-fail bug in kqueue by providing kevent() room to report errors Apparently, kevent fails gracefully if there is not enough space in its output events array to report every _event_... but it just dies and returns -1 if there is not enough space to report every _error_. There are a couple of possible fixes here. One would to handle -1 returns from kevent better by re-growing the array and retrying... but that seems a little error prone. Instead, I'm just going to say that the events array must be large enough to handle all the errors. This patch also adds a unit test designed to make sure that our many-events-out code works even if not all the events are added at once.

Nick Mathewson 3225dfb9 2010-01-14T17:04:08 Remove kqueue->pend_changes. Since we're no longer writing directly to it from add/del, we don't need to worry about it changing as kq_dispatch releases the lock. We would make it a local variable, except that we wouldn't want to malloc and free it all the time.
Nick Mathewson 45e5ae37 2010-01-14T16:31:05 Make kqueue use changelists. This fixes a bug in kqueue identified by Charles Kerr and various Transmission users, where adding and deleting an event in succession would make the event get reported, even if we didn't actually want to see it. Of course, this also makes the array of changes passed to kevent smaller, which could help performance.
William Ahern 56771a3e 2009-11-29T10:20:46 Valgrind fix: Clear struct kevent before checking for OSX bug. William's original commit message: Valgrind complains on startup because kq_init passes to kevent only a partially initialized structure. The code doesn't expect kevent to look at .fflags, .udata, or .data, I suppose, because it merely tickles the kernel looking for an error response. But perhaps that's unwarranted chuminess (notwithstanding that it's checking for an OS X bug), and needless noise nonetheless.
Nick Mathewson 76cd2b70 2009-11-27T16:44:47 Stop passing EVTHREAD_READ and EVTHREAD_WRITE to non-rw locks. Previously, our default lock model kind of assumed that every lock was potentially a read-write lock. This was a poor choice, since read-write locks are far more expensive than regular locks, and so the lock API should only use them when we can actually take advantage of them. Neither our pthreads or win32 lock implementation provided rw locks. Now that we have a way (not currently used!) to indicate that we really want a read-write lock, we shouldn't actually say "lock this for reading" or "lock this for writing" unless we mean it.
Nick Mathewson e1ffbb82 2009-11-21T01:11:49 Fix memory-leak of signal handler array with kqueue. It turns out that kqueue_dealloc wasn't calling evsig_dealloc() (because it doesn't use the main signal handler logic) so the sh_old array was leaking. This patch also introduces a fix in evsig_dealloc() where we set the sh_old array to NULL when we free it, so that main/fork can pass.

Nick Mathewson 0fd0255f 2009-11-03T19:54:56 Remove compat/sys/_time.h I've gone through everything that it declared to see where it was used, and it seems that we probably don't need it anywhere. Here's what it declared, and why I think we're okay dropping it. o struct timeval {} (Used all over, and we can't really get away with declaring it ourselves; we need the same definition the system uses. If we can't find struct timeval, we're pretty much sunk.) o struct timespec {} (Used in event.c, evdns.c, kqueue.c, evport.c. Of these, kqueue.c and event.c include sys/_time.h. event.c conditions its use on _EVENT_HAVE_CLOCK_GETTIME, and kqueue() only works if timespec is defined.) o TIMEVAL_TO_TIMESPEC (Used in kqueue.c, but every place with kqueue has sys/time.h) o struct timezone {} (event2/util.h has a forward declaration; only evutil.c references it and doesn't look at its contents.) o timerclear, timerisset, timercmp, timeradd, timersub (Everything now uses the evutil_timer* variants.) o ITIMER_REAL, ITIMER_VIRTUAL, ITIMER_PROF, struct itemerval (These are only used in test/regress.c, which does not include _time.h) o CLOCK_REALTIME (Only used in evdns.c, which does not include _time.h) o TIMESPEC_TO_TIMEVAL o DST_* o timespecclear, timespecisset, timespeccmp, timespecadd, timespecsub o struct clockinfo {} o CLOCK_VIRTUAL, CLOCK_PROF o TIMER_RELTIME, TIMER_ABSTIME (unused) svn:r1494

Nick Mathewson 6b22e74a 2009-10-21T03:54:00 Add locking to event_base_loop. This is harder than it sounds, since we need to make sure to release the lock around the key call to the kernel (e.g., select, epoll_wait, kevent), AND we need to make sure that none of the fields that are used in that call are touched by anything that might be running concurrently in another thread. I managed to do this pretty well for everything but poll(). With poll, I needed to introduce a copy of the event_set structure. This patch also fixes a bug in win32.c where we called realloc() instead of mm_realloc(). svn:r1450
