7 | - incompatible change: do not necessarily reset signal handler |
|
|
8 | to SIG_DFL when a sighandler is stopped. |
|
|
9 | - ev_default_destroy did not properly free or zero some members, |
|
|
10 | potentially causing crashes and memory corruption on repated |
|
|
11 | ev_default_destroy/ev_default_loop calls. |
|
|
12 | - take advantage of signalfd on GNU/Linux systems. |
|
|
13 | - document that the signal mask might be in an unspecified |
|
|
14 | state when using libev's signal handling. |
|
|
15 | - take advantage of some GNU/Linux calls to set cloexec/nonblock |
|
|
16 | on fd creation, to avoid race conditions. |

|
|
19 | - ev_unloop and ev_loop wrongly used a global variable to exit loops, |
|
|
20 | instead of using a per-loop variable (bug caught by accident...). |
|
|
21 | - the ev_set_io_collect_interval interpretation has changed. |
|
|
22 | - add new functionality: ev_set_userdata, ev_userdata, |
|
|
23 | ev_set_invoke_pending_cb, ev_set_loop_release_cb, |
|
|
24 | ev_invoke_pending, ev_pending_count, together with a long example |
|
|
25 | about thread locking. |
|
|
26 | - add ev_timer_remaining (as requested by Denis F. Latypoff). |
|
|
27 | - add ev_loop_depth. |
|
|
28 | - calling ev_unloop in fork/prepare watchers will no longer poll |
|
|
29 | for new events. |
|
|
30 | - Denis F. Latypoff corrected many typos in example code snippets. |
|
|
31 | - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double- |
|
|
32 | check that the syscall number is available before trying to |
|
|
33 | use it (reported by ry@tinyclouds). |
|
|
34 | - use GetSystemTimeAsFileTime instead of _timeb on windows, for |
|
|
35 | slightly higher accuracy. |
|
|
36 | - properly declare ev_loop_verify and ev_now_update even when |
|
|
37 | !EV_MULTIPLICITY. |
|
|
38 | - do not compile in any priority code when EV_MAXPRI == EV_MINPRI. |
|
|
39 | - support EV_MINIMAL==2 for a reduced API. |
|
|
40 | - actually 0-initialise struct sigaction when installing signals. |
|
|
41 | - add section on hibernate and stopped processes to ev_timer docs. |
|
|
42 | |
|
|
43 | 3.6 Tue Apr 28 02:49:30 CEST 2009 |
|
|
44 | - multiple timers becoming ready within an event loop iteration |
|
|
45 | will be invoked in the "correct" order now. |
|
|
46 | - do not leave the event loop early just because we have no active |
|
|
47 | watchers, fixing a problem when embedding a kqueue loop |
|
|
48 | that has active kernel events but no registered watchers |
|
|
49 | (reported by blacksand blacksand). |
|
|
50 | - correctly zero the idx values for arrays, so destroying and |
|
|
51 | reinitialising the default loop actually works (patch by |
|
|
52 | Malek Hadj-Ali). |
|
|
53 | - implement ev_suspend and ev_resume. |
|
|
54 | - new EV_CUSTOM revents flag for use by applications. |
|
|
55 | - add documentation section about priorites. |
|
|
56 | - add a glossary to the dcoumentation. |
|
|
57 | - extend the ev_fork description slightly. |
|
|
58 | - optimize a jump out of call_pending. |
|
|
59 | |
|
|
60 | 3.53 Sun Feb 15 02:38:20 CET 2009 |
|
|
61 | - fix a bug in event pipe creation on win32 that would cause a |
|
|
62 | failed assertion on event loop creation (patch by Malek Hadj-Ali). |
|
|
63 | - probe for CLOCK_REALTIME support at runtime as well and fall |
|
|
64 | back to gettimeofday if there is an error, to support older |
|
|
65 | operating systems with newer header files/libraries. |
|
|
66 | - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL |
|
|
67 | (default most everywhere), otherwise not. |
|
|
68 | |
|
|
69 | 3.52 Wed Jan 7 21:43:02 CET 2009 |
|
|
70 | - fix compilation of select backend in fd_set mode when NFDBITS is |
|
|
71 | missing (to get it to compile on QNX, reported by Rodrigo Campos). |
|
|
72 | - better select-nfds handling when select backend is in fd_set mode. |
|
|
73 | - diagnose fd_set overruns when select backend is in fd_set mode. |
|
|
74 | - due to a thinko, instead of disabling everything but |
|
|
75 | select on the borked OS X platform, everything but select was |
|
|
76 | allowed (reported by Emanuele Giaquinta). |
|
|
77 | - actually verify that local and remote port are matching in |
|
|
78 | libev's socketpair emulation, which makes denial-of-service |
|
|
79 | attacks harder (but not impossible - it's windows). Make sure |
|
|
80 | it even works under vista, which thinks that getpeer/sockname |
|
|
81 | should return fantasy port numbers. |
|
|
82 | - include "libev" in all assertion messages for potentially |
|
|
83 | clearer diagnostics. |
|
|
84 | - event_get_version (libevent compatibility) returned |
|
|
85 | a useless string instead of the expected version string |
|
|
86 | (patch by W.C.A. Wijngaards). |
|
|
87 | |
|
|
88 | 3.51 Wed Dec 24 23:00:11 CET 2008 |
|
|
89 | - fix a bug where an inotify watcher was added twice, causing |
|
|
90 | freezes on hash collisions (reported and analysed by Graham Leggett). |
|
|
91 | - new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use |
|
|
92 | a direct syscall - slower, but no dependency on librt et al. |
|
|
93 | - assume negative return values != -1 signals success of port_getn |
|
|
94 | (http://cvs.epicsol.org/cgi/viewcvs.cgi/epic5/source/newio.c?rev=1.52) |
|
|
95 | (no known failure reports, but it doesn't hurt). |
|
|
96 | - fork detection in ev_embed now stops and restarts the watcher |
|
|
97 | automatically. |
|
|
98 | - EXPERIMENTAL: default the method to operator () in ev++.h, |
|
|
99 | to make it nicer to use functors (requested by Benedek László). |
|
|
100 | - fixed const object callbacks in ev++.h. |
|
|
101 | - replaced loop_ref argument of watcher.set (loop) by a direct |
|
|
102 | ev_loop * in ev++.h, to avoid clashes with functor patch. |
|
|
103 | - do not try to watch the empty string via inotify. |
|
|
104 | - inotify watchers could be leaked under certain circumstances. |
|
|
105 | - OS X 10.5 is actually even more broken than earlier versions, |
|
|
106 | so fall back to select on that piece of garbage. |
|
|
107 | - fixed some weirdness in the ev_embed documentation. |
