2 2
3TODO: ev_loop_wakeup 34.26 (no standalone release)
4TODO: EV_STANDALONE == NO_HASSEL (do not use clock_gettime in ev_standalone) 4 - update to libec 0x00010006.
5TODO: faq, process a thing in each iteration 5 - new experimental linux aio backend (linux 4.18+).
6TODO: dbeugging tips, ev_verify, ev_init twice 6 - removed redundant 0-ptr check in ev_once.
7 - updated/extended ev_set_allocator documentation.
8 - replaced EMPTY2 macro by array_needsize_noinit.
9 - minor code cleanups.
10 - epoll backend now uses epoll_create1 also after fork.

124.25 Fri Dec 21 07:49:20 CET 2018
13 - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
14 (EV_THROW still provided) and now uses noexcept on C++11 or newer.
15 - move the darwin select workaround highe rin ev.c, as newer versions of
16 darwin managed to break their broken select even more.
17 - ANDROID => __ANDROID__ (reported by enh@google.com).
18 - disable epoll_create1 on android because it has broken header files
19 and google is unwilling to fix them (reported by enh@google.com).
20 - avoid a minor compilation warning on win32.
21 - c++: remove deprecated dynamic throw() specifications.
22 - c++: improve the (unsupported) bad_loop exception class.
23 - backport perl ev_periodic example to C, untested.
24 - update libecb, biggets change is to include a memory fence
25 in ECB_MEMORY_FENCE_RELEASE on x86/amd64.
26 - minor autoconf/automake modernisation.
27
284.24 Wed Dec 28 05:19:55 CET 2016
29 - bump version to 4.24, as the release tarball inexplicably
30 didn't have the right version in ev.h, even though the cvs-tagged
31 version did have the right one (reported by Ales Teska).
32
334.23 Wed Nov 16 18:23:41 CET 2016
34 - move some declarations at the beginning to help certain retarded
35 microsoft compilers, even though their documentation claims
36 otherwise (reported by Ruslan Osmanov).
37
384.22 Sun Dec 20 22:11:50 CET 2015
39 - when epoll detects unremovable fds in the fd set, rebuild
40 only the epoll descriptor, not the signal pipe, to avoid
41 SIGPIPE in ev_async_send. This doesn't solve it on fork,
42 so document what needs to be done in ev_loop_fork
43 (analyzed by Benjamin Mahler).
44 - remove superfluous sys/timeb.h include on win32
45 (analyzed by Jason Madden).
46 - updated libecb.
47
484.20 Sat Jun 20 13:01:43 CEST 2015
49 - prefer noexcept over throw () with C++ 11.
50 - update ecb.h due to incompatibilities with c11.
51 - fix a potential aliasing issue when reading and writing
52 watcher callbacks.
53
544.19 Thu Sep 25 08:18:25 CEST 2014
55 - ev.h wasn't valid C++ anymore, which tripped compilers other than
56 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
57 C++ doesn't support typedefs for function pointers fully, so the affected
58 declarations have to spell out the types each time.
59 - when not using autoconf, tighten the check for clock_gettime and related
60 functionality.
61
624.18 Fri Sep 5 17:55:26 CEST 2014
63 - events on files were not always generated properly with the
64 epoll backend (testcase by Assaf Inbal).
65 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
66 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
67 - use a reasonable fallback for EV_NSIG instead of erroring out
68 when we can't detect the signal set size.
69 - in the absence of autoconf, do not use the clock syscall
70 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
71 doing clock_gettime in userspace).
72 - ensure extern "C" function pointers are used for externally-visible
73 loop callbacks (not watcher callbacks yet).
74 - (ecb) work around memory barriers and volatile apparently both being
75 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).

78 - destroying a non-default loop would stop the global waitpid
79 watcher (Denis Bilenko).

13 syserr, loop acquire/release, periodic reschedule cbs). 85 syserr, loop acquire/release, periodic reschedule cbs).
14 - fix event_base_loop return code, add event_get_callback, event_base_new, 86 - fix event_base_loop return code, add event_get_callback, event_base_new,
15 event_base_get_method calls to improve libevent 1.x emulation and add 87 event_base_get_method calls to improve libevent 1.x emulation and add
16 some libevent 2.x funcitonality (based on a patch by Jeff Davey). 88 some libevent 2.x functionality (based on a patch by Jeff Davey).

101 in many cases.

33 works in all cases (unlike read/write/send/recv...). 107 works in all cases (unlike read/write/send/recv...).
108 - try to detect signals around a fork faster (test program by
109 Denis Bilenko).
110 - work around recent glibc versions that leak memory in realloc.
111 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
112 the watcher base set (loop) method.
113 - rewrite the async/signal pipe logic to always keep a valid fd, which
114 simplifies (and hopefully correctifies :) the race checking
115 on fork, at the cost of one extra fd.
116 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
117 inotify-supporting filesystems.
118 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
119 versions ignore it before
120 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
121 - add some untested android support.
122 - enum expressions must be of type int (reported by Juan Pablo L).
