2 2
3TODO: ev_walk 3TODO: ABI??? API????? Changes???
4TODO: remain 4 - ev_embed_stop did not correctly stop the watcher (very good
5TODO: EV_MINIMAL 5 testcase by Vladimir Timofeev).
6 - applied win32 fixes by Michael Lenaghan (also James Mansion).
7 - replace EV_MINIMAL by EV_FEATURES.
8 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
9 - configure now prepends -O3, not appends it, so one can still
10 override it.
11 - disable poll backend on AIX, the poll header spams the namespace
12 and it's not worth working around dead platforms (reported
13 and analyzed by Aivars Kalvans).
14 - improve header file compatibility of the standalone eventfd code
15 in an obscure case.
16 - implement EV_AVOID_STDIO option.
17 - do not use sscanf to parse linux version number (smaller, faster,
18 no sscanf dependency).
19 - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
20 - update libev.m4 HAVE_CLOCK_SYSCALL test for newwer glibcs.
21 - add section on accept() problems to the manpage.

7 - new functionality: ev_set_userdata, ev_userdata, 233.9 Thu Dec 31 07:59:59 CET 2009
8 ev_set_invoke_pending_cb, ev_set_loop_release_cb, 24 - signalfd is no longer used by default and has to be requested
9 ev_invoke_pending, together with a long example about thread 25 explicitly - this means that easy to catch bugs become hard to
10 locking. 26 catch race conditions, but the users have spoken.
27 - point out the unspecified signal mask in the documentation, and
28 that this is a race condition regardless of EV_SIGNALFD.
29 - backport inotify code to C89.
30 - inotify file descriptors could leak into child processes.
31 - ev_stat watchers could keep an errornous extra ref on the loop,
32 preventing exit when unregistering all watchers (testcases
33 provided by ry@tinyclouds.org).
34 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
35 symbols to make it easier for apps to do their own fd management.
36 - support EV_IDLE_ENABLE being disabled in ev++.h
37 (patch by Didier Spezia).
38 - take advantage of inotify_init1, if available, to set cloexec/nonblock
39 on fd creation, to avoid races.
40 - the signal handling pipe wasn't always initialised under windows
41 (analysed by lekma).
42 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
43 signalfd.
44 - add missing string.h include (Denis F. Latypoff).
45 - only replace ev_stat.prev when we detect an actual difference,
46 so prev is (almost) always different to attr. this might
47 have caused the probems with 04_stat.t.
48 - add ev::timer->remaining () method to C++ API.

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

11 - ev_unloop and ev_loop wrongly used a global variable to exit loops, 63 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
12 instead of using a per-loop variable (bug caught by accident...). 64 instead of using a per-loop variable (bug caught by accident...).
65 - the ev_set_io_collect_interval interpretation has changed.
66 - add new functionality: ev_set_userdata, ev_userdata,
67 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
68 ev_invoke_pending, ev_pending_count, together with a long example
69 about thread locking.
70 - add ev_timer_remaining (as requested by Denis F. Latypoff).
71 - add ev_loop_depth.
13 - calling ev_unloop in fork/prepare watchers will no longer poll 72 - calling ev_unloop in fork/prepare watchers will no longer poll
14 for new events. 73 for new events.
15 - Denis F. Latypoff corrected many typos in example code snippets. 74 - Denis F. Latypoff corrected many typos in example code snippets.
16 - the ev_set_io_collect_interval interpretation has changed.
17 - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double- 75 - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
18 check that the syscall number is available before trying to 76 check that the syscall number is available before trying to
19 use it (reported by ry@tinyclouds). 77 use it (reported by ry@tinyclouds).
20 - use GetSystemTimeAsFileTime instead of _timeb on windows, for 78 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
21 slightly higher accuracy. 79 slightly higher accuracy.
22 - properly declare ev_loop_verify and ev_now_update even when 80 - properly declare ev_loop_verify and ev_now_update even when
23 !EV_MULTIPLICITY. 81 !EV_MULTIPLICITY.
24 - implement ev_loop_depth.
25 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI. 82 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
26 - support EV_MINIMAL==2 for a reduced API. 83 - support EV_MINIMAL==2 for a reduced API.
27 - actually 0-initialise struct sigaction when installing signals. 84 - actually 0-initialise struct sigaction when installing signals.
