|
3 | - applied win32 fixes by Michael Lenaghan. |
|
|
4 | - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu). |
|
|
5 | - configure now prepends -O3, not appends it, so one can still |
|
|
6 | override it. |

8 | 3.9 Thu Dec 31 07:59:59 CET 2009 |
|
|
9 | - signalfd is no longer used by default and has to be requested |
|
|
10 | explicitly - this means that easy to catch bugs become hard to |
|
|
11 | catch race conditions, but the users have spoken. |
|
|
12 | - point out the unspecified signal mask in the documentation, and |
|
|
13 | that this is a race condition regardless of EV_SIGNALFD. |
|
|
14 | - backport inotify code to C89. |
|
|
15 | - inotify file descriptors could leak into child processes. |
|
|
16 | - ev_stat watchers could keep an errornous extra ref on the loop, |
|
|
17 | preventing exit when unregistering all watchers (testcases |
|
|
18 | provided by ry@tinyclouds.org). |
|
|
19 | - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration |
|
|
20 | symbols to make it easier for apps to do their own fd management. |
|
|
21 | - support EV_IDLE_ENABLE being disabled in ev++.h |
|
|
22 | (patch by Didier Spezia). |
|
|
23 | - take advantage of inotify_init1, if available, to set cloexec/nonblock |
|
|
24 | on fd creation, to avoid races. |
|
|
25 | - the signal handling pipe wasn't always initialised under windows |
|
|
26 | (analysed by lekma). |
|
|
27 | - changed minimum glibc requirement from glibc 2.9 to 2.7, for |
|
|
28 | signalfd. |
|
|
29 | - add missing string.h include (Denis F. Latypoff). |
|
|
30 | - only replace ev_stat.prev when we detect an actual difference, |
|
|
31 | so prev is (almost) always different to attr. this might |
|
|
32 | have caused the probems with 04_stat.t. |
|
|
33 | - add ev::timer->remaining () method to C++ API. |
|
|
34 | |
|
|
35 | 3.8 Sun Aug 9 14:30:45 CEST 2009 |
|
|
36 | - incompatible change: do not necessarily reset signal handler |
|
|
37 | to SIG_DFL when a sighandler is stopped. |
|
|
38 | - ev_default_destroy did not properly free or zero some members, |
|
|
39 | potentially causing crashes and memory corruption on repated |
|
|
40 | ev_default_destroy/ev_default_loop calls. |
|
|
41 | - take advantage of signalfd on GNU/Linux systems. |
|
|
42 | - document that the signal mask might be in an unspecified |
|
|
43 | state when using libev's signal handling. |
|
|
44 | - take advantage of some GNU/Linux calls to set cloexec/nonblock |
|
|
45 | on fd creation, to avoid race conditions. |
|
|
46 | |
|
|
47 | 3.7 Fri Jul 17 16:36:32 CEST 2009 |
|
|
48 | - ev_unloop and ev_loop wrongly used a global variable to exit loops, |
|
|
49 | instead of using a per-loop variable (bug caught by accident...). |
|
|
50 | - the ev_set_io_collect_interval interpretation has changed. |
|
|
51 | - add new functionality: ev_set_userdata, ev_userdata, |
|
|
52 | ev_set_invoke_pending_cb, ev_set_loop_release_cb, |
|
|
53 | ev_invoke_pending, ev_pending_count, together with a long example |
|
|
54 | about thread locking. |
|
|
55 | - add ev_timer_remaining (as requested by Denis F. Latypoff). |
|
|
56 | - add ev_loop_depth. |
|
|
57 | - calling ev_unloop in fork/prepare watchers will no longer poll |
|
|
58 | for new events. |
|
|
59 | - Denis F. Latypoff corrected many typos in example code snippets. |
|
|
60 | - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double- |
|
|
61 | check that the syscall number is available before trying to |
|
|
62 | use it (reported by ry@tinyclouds). |
|
|
63 | - use GetSystemTimeAsFileTime instead of _timeb on windows, for |
|
|
64 | slightly higher accuracy. |
|
|
65 | - properly declare ev_loop_verify and ev_now_update even when |
|
|
66 | !EV_MULTIPLICITY. |
|
|
67 | - do not compile in any priority code when EV_MAXPRI == EV_MINPRI. |
|
|
68 | - support EV_MINIMAL==2 for a reduced API. |
|
|
69 | - actually 0-initialise struct sigaction when installing signals. |
|
|
70 | - add section on hibernate and stopped processes to ev_timer docs. |
|
|
71 | |
|
|
72 | 3.6 Tue Apr 28 02:49:30 CEST 2009 |
|
|
73 | - multiple timers becoming ready within an event loop iteration |
|
|
74 | will be invoked in the "correct" order now. |
|
|
75 | - do not leave the event loop early just because we have no active |
|
|
76 | watchers, fixing a problem when embedding a kqueue loop |
|
|
77 | that has active kernel events but no registered watchers |
|
|
78 | (reported by blacksand blacksand). |
|
|
79 | - correctly zero the idx values for arrays, so destroying and |
|
|
80 | reinitialising the default loop actually works (patch by |
|
|
81 | Malek Hadj-Ali). |
|
|
82 | - implement ev_suspend and ev_resume. |
|
|
83 | - new EV_CUSTOM revents flag for use by applications. |
|
|
84 | - add documentation section about priorites. |
|
|
85 | - add a glossary to the dcoumentation. |
|
|
86 | - extend the ev_fork description slightly. |
|
|
87 | - optimize a jump out of call_pending. |
|
|
88 | |
|
|
89 | 3.53 Sun Feb 15 02:38:20 CET 2009 |
|
|
90 | - fix a bug in event pipe creation on win32 that would cause a |
|
|
91 | failed assertion on event loop creation (patch by Malek Hadj-Ali). |
|
|
92 | - probe for CLOCK_REALTIME support at runtime as well and fall |
|
|
93 | back to gettimeofday if there is an error, to support older |
|
|
94 | operating systems with newer header files/libraries. |
|
|
95 | - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL |
|
|
96 | (default most everywhere), otherwise not. |
|
|
