2 2
3TODO: ev_walk 3 - ev_embed_stop did not correctly stop the watcher (very good
4TODO: remain 4 testcase by Vladimir Timofeev).
5TODO: on_call_pending, on_suspend_resume ev_invoke_pending (EV_P) 5 - applied win32 fixes by Michael Lenaghan.
6TODO: EV_MINIMAL 6 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
7 - configure now prepends -O3, not appends it, so one can still
8 override it.
9 - disable poll backend on AIX, the poll header spams the namespace
10 and it's not worth working around dead platforms (reported
11 and analyzed by Aivars Kalvans).
12 - improve header file compatibility of the standalone eventfd code
13 in an obscure case.

16 - signalfd is no longer used by default and has to be requested
17 explicitly - this means that easy to catch bugs become hard to
18 catch race conditions, but the users have spoken.
19 - point out the unspecified signal mask in the documentation, and
20 that this is a race condition regardless of EV_SIGNALFD.
21 - backport inotify code to C89.
22 - inotify file descriptors could leak into child processes.
23 - ev_stat watchers could keep an errornous extra ref on the loop,
24 preventing exit when unregistering all watchers (testcases
25 provided by ry@tinyclouds.org).
26 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
27 symbols to make it easier for apps to do their own fd management.
28 - support EV_IDLE_ENABLE being disabled in ev++.h
29 (patch by Didier Spezia).
30 - take advantage of inotify_init1, if available, to set cloexec/nonblock
31 on fd creation, to avoid races.
32 - the signal handling pipe wasn't always initialised under windows
33 (analysed by lekma).
34 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
35 signalfd.
36 - add missing string.h include (Denis F. Latypoff).
37 - only replace ev_stat.prev when we detect an actual difference,
38 so prev is (almost) always different to attr. this might
39 have caused the probems with 04_stat.t.
40 - add ev::timer->remaining () method to C++ API.

43 - incompatible change: do not necessarily reset signal handler
44 to SIG_DFL when a sighandler is stopped.
45 - ev_default_destroy did not properly free or zero some members,
46 potentially causing crashes and memory corruption on repated
47 ev_default_destroy/ev_default_loop calls.
48 - take advantage of signalfd on GNU/Linux systems.
49 - document that the signal mask might be in an unspecified
50 state when using libev's signal handling.
51 - take advantage of some GNU/Linux calls to set cloexec/nonblock
52 on fd creation, to avoid race conditions.

7 - ev_unloop and ev_loop wrongly used a global variable to exit loops, 55 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
8 instead of using a per-loop variable (bug caught by accident...). 56 instead of using a per-loop variable (bug caught by accident...).
57 - the ev_set_io_collect_interval interpretation has changed.
58 - add new functionality: ev_set_userdata, ev_userdata,
59 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
60 ev_invoke_pending, ev_pending_count, together with a long example
61 about thread locking.
62 - add ev_timer_remaining (as requested by Denis F. Latypoff).
63 - add ev_loop_depth.
9 - calling ev_unloop in fork/prepare watchers will no longer poll 64 - calling ev_unloop in fork/prepare watchers will no longer poll
10 for new events. 65 for new events.
11 - Denis F. Latypoff corrected many typos in example code snippets. 66 - Denis F. Latypoff corrected many typos in example code snippets.
12 - the ev_set_io_collect_interval interpretation has changed.
13 - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double- 67 - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
14 check that the syscall number is available before trying to 68 check that the syscall number is available before trying to
15 use it (reported by ry@tinyclouds). 69 use it (reported by ry@tinyclouds).
16 - use GetSystemTimeAsFileTime instead of _timeb on windows, for 70 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
17 slightly higher accuracy. 71 slightly higher accuracy.
18 - properly declare ev_loop_verify and ev_now_update even when 72 - properly declare ev_loop_verify and ev_now_update even when
19 !EV_MULTIPLICITY. 73 !EV_MULTIPLICITY.
20 - implement ev_loop_depth.
21 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI. 74 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
22 - support EV_MINIMAL==2 for a reduced API. 75 - support EV_MINIMAL==2 for a reduced API.
76 - actually 0-initialise struct sigaction when installing signals.
77 - add section on hibernate and stopped processes to ev_timer docs.
