9b724b28 | 2011-08-11 03:10:08 | Fix evsig_dealloc memory leak with debugging turned on. | |
|
b683cae3 | 2011-04-22 12:01:25 | Avoid race-condition when initializing global locks Previously, we did stuff like if (!lock) EVTHREAD_ALLOC_LOCK(lock,0); for the evsig base global lock, the arc4random lock, and the debug_map lock. But that's potentially racy! Instead, we move the responisiblity for global lock initialization to the functions where we set up the lock callbacks. (Rationale: We already require that you set up the locking callbacks before you create any event_base, and that you do so exatly once.) | |

|
5b7a3706 | 2010-10-05 14:29:48 | Fix warnings on mingw with gcc 4.5 | |
|
90651b32 | 2010-09-17 00:24:50 | Put internal events at highest priority (If we allow user events to starve internal events, then internal events never actually happen, signals don't get acked, etc) | |
|
38d09606 | 2010-09-15 12:50:31 | Remove event_base.evsigbase; nothing used it. | |
|
4858b794 | 2010-09-15 01:54:51 | Remove the now-useless evsig_caught and evsig_process | |
|
95a7d418 | 2010-09-15 01:40:02 | Make default signal backend fully threadsafe Jason Toffaletti discovered with helgrind that our signal handler was messing with evsig_base, which can be set from lots of places in the code. Ordinarly, we'd just stick a lock on it, except that it is illegal (and genuinely error-prone) to call pthread_mutex_acquire() from inside a signal handler. The solution is to only store the fd we write to in a static variable, write the signal number to the fd, and put evsig_cb in charge of activating signal events. I have no idea how we'll cope if we want to enable this to handle siginfo (where available) in the future. | |
|
720bd933 | 2010-09-15 01:08:39 | Warn when using the error-prone EV_SIGNAL interface in an error-prone way. Also, fix a couple of race conditions in signal.c When using the signal.c signal backend, Libevent currently only allows one event_base to actually receive signals at a time. (This has been the behavior since at least 1.4 and probably much earlier.) Now, we detect and warn if you're likely to be racing about which signal goes to which thread. We also add a lock to control modifications of the evsig_base field, to avoid race conditions like those found by Jason Toffaletti. Also, more comments. Comments are good. | |

47882773 | 2010-09-02 13:21:17 | Fix pointer-to-__cdecl-function syntax | |
|
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. | |
|
970e6ad2 | 2010-08-19 14:00:06 | Avoid deadlock when activating signals. Fixes bug 3048812. Based on patch by Nicholas Marriott. | |
|
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. | |
 |
b84b598e | 2010-04-21 01:15:19 | Clean up properly when adding a signal handler fails. Previously, when a signation() or signal() call failed, we would free the element we added to sh_old, but not actually clear the pointer. This would leave a dangling pointer in sh_old that could cause a crash later. | |
 |
899c1dcc | 2010-04-14 15:42:57 | Replace EVUTIL_CLOSESOCKET macro with a function The EVUTIL_CLOSESOCKET() macro required you to include unistd.h in your source for POSIX. We might as well turn it into a function: an extra function call is going to be cheap in comparison with the system call. We retain the EVUTIL_CLOSESOCKET() macro as an alias for the new evutil_closesocket() function. (commit message from email by Nick and Sebastian) | |
|
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. | |
|
a19b4a05 | 2010-01-25 13:38:07 | Call event_debug_unassign on internal events I don't expect that many users will be so religious about calling unassign, but we need to be so that it's at least possible to use debug mode without eating memory. | |
 |
d0939d2b | 2009-12-29 16:21:26 | Introduced evutil_make_socket_closeonexec() to preserve fd flags for F_SETFD. Use this to eliminate the various macros that called F_SETFD throughout the code. | |
|
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. | |
|
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 | |
|

|
7a844735 | 2009-05-22 17:20:05 | Fix some small win32 build issues on trunk. svn:r1306 | |
|
8c66eb2e | 2009-05-22 14:48:40 | Try to contain the failure when we are running without socketpair(). Some win32 systems (mostly those using Kaspersky, it would seem) prevent us from faking socketpair(). This makes our signal notification code just not work. Our response since 1.4 has been to assert. For users who would rather work without signals than not work at all, this has been a regression from 1.3e. This patch makes adding signal events fail in this case; there's no reason to kill the whole process. svn:r1303 | |
|
d3fbe7fa | 2009-04-21 18:47:53 | Do not free the signal index unless it was at some point allocated svn:r1217 | |

b85b710c | 2009-01-27 22:34:36 | Update copyright statements to reflect the facts that: a) this is 2009 b) niels and nick have been comaintainers for a while c) saying "all rights reserved" when you then go on to explicitly disclaim some rights is sheer cargo-cultism. svn:r1065 | |

|
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 | |
|
fded0a87 | 2008-09-05 16:47:04 | Fix compilation of recent error code with win32. svn:r937 | |
|
de069b99 | 2008-09-05 16:29:56 | On win32, errno is not the last socket error. Worse, WSAGetLastError() is not the last socket error sometimes (i.e., EWOULDBLOCK). Also, strerror() does not handle winsock errors. Therefore, event_err() and event_warn() are completely wrong for windows socket errors. Fix that. svn:r936 | |
