28317a08 | 2011-05-03 13:54:57 | 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. | |

5e4bafbb | 2010-10-14 13:15:32 | fix a signed/unsigned warning in kqueue.c | |
 |
b3953927 | 2010-09-27 21:14:28 | Fix compile in kqueue.c Commit 38d09606 removed the evsigbase pointer, but forgot to remove an assignment to it in kqueue.c. | |
|
4858b794 | 2010-09-15 01:54:51 | Remove the now-useless evsig_caught and evsig_process | |
|
ec347b92 | 2010-07-07 16:45:03 | Move event-config.h to include/event2 This change means that all required include files are in event2, and all files not in event2/* are optional. | |
|
2c2618d8 | 2010-03-05 13:00:15 | more whitespace normalization | |
|
17efc1cd | 2010-03-04 01:25:51 | Update all our copyright notices to say "2010" | |
|
e5bbd40a | 2010-02-18 17:41:15 | Clean up formatting: use tabs, not 8-spaces, to indent. | |
|
3225dfb9 | 2010-01-14 17:04:08 | 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. | |
|
45e5ae37 | 2010-01-14 16:31:05 | 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. | |
 |
56771a3e | 2009-11-29 10:20:46 | 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. | |
|
76cd2b70 | 2009-11-27 16:44:47 | 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. | |
|
e1ffbb82 | 2009-11-21 01:11:49 | 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. | |
|
18a8cfac | 2009-11-15 19:00:12 | Prefer calloc(a,b) to malloc(a*b). via openbsd. svn:r1531 | |

784b8773 | 2009-11-06 21:46:57 | We do not work any more without an event-config.h; stop pretending that it is meaningful to check for HAVE_CONFIG_H svn:r1516 | |
|
4d48cf61 | 2009-11-06 21:13:25 | Fix kqueue.c build on GNU/kFreeBSD systems. Yes, some people like to have a BSD-family kernel (thus getting kqueue) with a GNU-family libc (thus occasionally mandating _GNU_SOURCE). Thanks to Debian for noticing this. svn:r1514 | |
|
0fd0255f | 2009-11-03 19:54:56 | 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 | |

|
6b22e74a | 2009-10-21 03:54:00 | 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 | |

02b2b4d1 | 2008-12-23 16:37:01 | Restructure the event backends so that they do not need to keep track of events themselves, as a side effect multiple events can use the same fd or signal. svn:r972 | |
|
