3TODO: ev_loop_wakeup 34.25 Fri Dec 21 07:49:20 CET 2018
4TODO: EV_STANDALONE == NO_HASSEL (do not use clock_gettime in ev_standalone) 4 - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
5TODO: faq, process a thing in each iteration 5 (EV_THROW sitll provided) and now uses noexcept on C++11 or newer.
6TODO: dbeugging tips, ev_verify, ev_init twice 6 - move the darwin select workaround highe rin ev.c, as newer versions of
7 darwin managed to break their broken select even more.
8 - ANDROID => __ANDROID__ (reported by enh@google.com).
9 - disable epoll_create1 on android because it has broken header files
10 and google is unwilling to fix them (reported by enh@google.com).
11 - avoid a minor compilation warning on win32.
12 - c++: remove deprecated dynamic throw() specifications.
13 - c++: improve the (unsupported) bad_loop exception class.
14 - backport perl ev_periodic example to C, untested.
15 - update libecb, biggets change is to include a memory fence
16 in ECB_MEMORY_FENCE_RELEASE on x86/amd64.

184.24 Wed Dec 28 05:19:55 CET 2016
19 - bump version to 4.24, as the release tarball inexplicably
20 didn't have the right version in ev.h, even though the cvs-tagged
21 version did have the right one (reported by Ales Teska).
22
234.23 Wed Nov 16 18:23:41 CET 2016
24 - move some declarations at the beginning to help certain retarded
25 microsoft compilers, even though their documentation claims
26 otherwise (reported by Ruslan Osmanov).
27
284.22 Sun Dec 20 22:11:50 CET 2015
29 - when epoll detects unremovable fds in the fd set, rebuild
30 only the epoll descriptor, not the signal pipe, to avoid
31 SIGPIPE in ev_async_send. This doesn't solve it on fork,
32 so document what needs to be done in ev_loop_fork
33 (analyzed by Benjamin Mahler).
34 - remove superfluous sys/timeb.h include on win32
35 (analyzed by Jason Madden).
36 - updated libecb.
37
384.20 Sat Jun 20 13:01:43 CEST 2015
39 - prefer noexcept over throw () with C++ 11.
40 - update ecb.h due to incompatibilities with c11.
41 - fix a potential aliasing issue when reading and writing
42 watcher callbacks.
43
444.19 Thu Sep 25 08:18:25 CEST 2014
45 - ev.h wasn't valid C++ anymore, which tripped compilers other than
46 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
47 C++ doesn't support typedefs for function pointers fully, so the affected
48 declarations have to spell out the types each time.
49 - when not using autoconf, tighten the check for clock_gettime and related
50 functionality.
51
524.18 Fri Sep 5 17:55:26 CEST 2014
53 - events on files were not always generated properly with the
54 epoll backend (testcase by Assaf Inbal).
55 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
56 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
57 - use a reasonable fallback for EV_NSIG instead of erroring out
58 when we can't detect the signal set size.
59 - in the absence of autoconf, do not use the clock syscall
60 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
61 doing clock_gettime in userspace).
62 - ensure extern "C" function pointers are used for externally-visible
63 loop callbacks (not watcher callbacks yet).
64 - (ecb) work around memory barriers and volatile apparently both being
65 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).

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