4f0f40e3 | 2018-02-27 21:12:14 | Fix base unlocking in event_del() if event_base_set() runned in another thread Image next situation: T1: T2: event_del_() lock the event.ev_base.th_base_lock event_del_nolock_() event_set_base() unlock the event.ev_base.th_base_lock In this case we will unlock the wrong base after event_del_nolock_() returns, and deadlock is likely to happens, since event_base_set() do not check any mutexes (due to it is possible to do this only if event is not inserted anywhere). So event_del_() has to cache the base before removing the event, and cached base.th_base_lock after. (cherry picked from commit 08a0d366073eacf800027725891c2f668f2f0144) | |

43d92a6d | 2017-08-07 11:06:28 | Fix race in access to ev_res from event loop with event_active() Detected using ThreadSanitizer, resolved by capturing the value of ev_res in a local variable while the event is locked, then passing that captured variable to the callback.

876c7ac7 | 2015-04-13 08:54:52 | Return from event_del() after the last event callback termination Delete the event from the queue before blocking for the current event callback termination. Ensures that no callback is being executed when event_del() returns, hence making this function a secure mechanism to access data which is handled in the event callack. Fixes: #236 Fixes: #225 Refs: 6b4b77a Fixes: del_wait (cherry picked from commit 0b4b0efdb8ee710ccae5bad320fc24843fd428e5) | |

9806b126 | 2017-03-13 21:05:32 | Merge branch 'cmake-missing-bits' This patchset adds next missing things (in compare to autotools): - pkgconfig - event_pthreads/event_openssl - compile shared/static libraries always And some fixes, because it will not build after fixing other things: - export missing symbols for cmake (-fvisibility=hidden) * cmake-missing-bits: cmake: support visibility for AppleClang too cmake: fix export absolute path and relative path and cleanup a bit cmake: generate and install pkgconfig files cmake: build SHARED and STATIC libraries (like autoconf does) cmake: add missing event_openssl/event_pthreads libraries Export symbols for -fvisibility=hidden (under cmake) Refs: #246 (cherry picked from commit 489991a2b2628ba1ff4e6879b9f67ec35d224c38) | |

88640aa1 | 2015-12-27 02:15:03 | event_reinit: make signals works after fork() without evsig_add() event_reinit() removes the event, but only evsig_add puts it back. So any signals set up before event_reinit will be ignored until another signal is added. Fixes: #307 | |

ad0c237b | 2015-12-27 01:43:37 | event_reinit: always re-init signal's socketpair Before this patch event_reinit() only closes the signal socketpair fds and recreates them if signals have been added, but this is wrong, since socketpair fds created on backend init, and if we will not re-create them bad things in child/parent signal handling will happens (and indeed this is what happens for non-reinit backends like select). Fixes: #307 |
