2 2
3TODO: ev_loop_wakeup 3 - removed redundant 0-ptr check in ev_once.
4TODO: EV_STANDALONE == NO_HASSEL (do not use clock_gettime in ev_standalone)
5 4
6TODO: document WSA_EV_USE_SOCKET in win32 part 54.25 Fri Dec 21 07:49:20 CET 2018
7TODO: ^ OR use WSASend/WSARecv on the handle, which always works 6 - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
8TODO: use __OPTIMIZE__ or __OPTIMIZE_SIZE__? 7 (EV_THROW still provided) and now uses noexcept on C++11 or newer.
8 - move the darwin select workaround highe rin ev.c, as newer versions of
9 darwin managed to break their broken select even more.
10 - ANDROID => __ANDROID__ (reported by enh@google.com).
11 - disable epoll_create1 on android because it has broken header files
12 and google is unwilling to fix them (reported by enh@google.com).
13 - avoid a minor compilation warning on win32.
14 - c++: remove deprecated dynamic throw() specifications.
15 - c++: improve the (unsupported) bad_loop exception class.
16 - backport perl ev_periodic example to C, untested.
17 - update libecb, biggets change is to include a memory fence
18 in ECB_MEMORY_FENCE_RELEASE on x86/amd64.
19 - minor autoconf/automake modernisation.

214.24 Wed Dec 28 05:19:55 CET 2016
22 - bump version to 4.24, as the release tarball inexplicably
23 didn't have the right version in ev.h, even though the cvs-tagged
24 version did have the right one (reported by Ales Teska).
25
264.23 Wed Nov 16 18:23:41 CET 2016
27 - move some declarations at the beginning to help certain retarded
28 microsoft compilers, even though their documentation claims
29 otherwise (reported by Ruslan Osmanov).

314.22 Sun Dec 20 22:11:50 CET 2015
32 - when epoll detects unremovable fds in the fd set, rebuild
33 only the epoll descriptor, not the signal pipe, to avoid
34 SIGPIPE in ev_async_send. This doesn't solve it on fork,
35 so document what needs to be done in ev_loop_fork
36 (analyzed by Benjamin Mahler).
37 - remove superfluous sys/timeb.h include on win32
38 (analyzed by Jason Madden).
39 - updated libecb.

414.20 Sat Jun 20 13:01:43 CEST 2015
42 - prefer noexcept over throw () with C++ 11.
43 - update ecb.h due to incompatibilities with c11.
44 - fix a potential aliasing issue when reading and writing
45 watcher callbacks.
46
474.19 Thu Sep 25 08:18:25 CEST 2014
48 - ev.h wasn't valid C++ anymore, which tripped compilers other than
49 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
50 C++ doesn't support typedefs for function pointers fully, so the affected
51 declarations have to spell out the types each time.
52 - when not using autoconf, tighten the check for clock_gettime and related
53 functionality.
54
554.18 Fri Sep 5 17:55:26 CEST 2014
56 - events on files were not always generated properly with the
57 epoll backend (testcase by Assaf Inbal).
58 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
59 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
60 - use a reasonable fallback for EV_NSIG instead of erroring out
61 when we can't detect the signal set size.
62 - in the absence of autoconf, do not use the clock syscall
63 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
64 doing clock_gettime in userspace).
65 - ensure extern "C" function pointers are used for externally-visible
66 loop callbacks (not watcher callbacks yet).
67 - (ecb) work around memory barriers and volatile apparently both being
68 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).

704.15 Fri Mar 1 12:04:50 CET 2013
71 - destroying a non-default loop would stop the global waitpid
72 watcher (Denis Bilenko).
73 - queueing pending watchers of higher priority from a watcher now invokes
74 them in a timely fashion (reported by Denis Bilenko).
75 - add throw() to all libev functions that cannot throw exceptions, for
76 further code size decrease when compiling for C++.
77 - add throw () to callbacks that must not throw exceptions (allocator,
78 syserr, loop acquire/release, periodic reschedule cbs).
10 - fix event_base_loop return code, add event_get_callback, event_base_new, 79 - fix event_base_loop return code, add event_get_callback, event_base_new,
11 event_base_get_method calls to improve libevent 1.x emulation and add 80 event_base_get_method calls to improve libevent 1.x emulation and add
12 some libevent 2.x funcitonality (based on a patch by Jeff Davey). 81 some libevent 2.x functionality (based on a patch by Jeff Davey).
82 - add more memory fences to fix a bug reported by Jeff Davey. Better
83 be overfenced than underprotected.
13 - ev_run now returns a boolean status (true meaning watchers are 84 - ev_run now returns a boolean status (true meaning watchers are
14 still active). 85 still active).
15 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with 86 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
16 libev's EV_ERROR (reported by 191919). 87 libev's EV_ERROR (reported by 191919).
17 - (ecb) add memory fence support for xlC (Darin McBride). 88 - (ecb) add memory fence support for xlC (Darin McBride).
18 - (ecb) add memory fence support for gcc-mips (Anton Kirilov). 89 - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
90 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
19 - work around some kernels losing file descriptors by leaking 91 - work around some kernels losing file descriptors by leaking
20 the kqueue descriptor in the child. 92 the kqueue descriptor in the child.
93 - work around linux inotify not reporting IN_ATTRIB changes for directories
94 in many cases.
95 - include sys/syscall.h instead of plain syscall.h.
96 - check for io watcher loops in ev_verify, check for the most
97 common reported usage bug in ev_io_start.
98 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
99 - always use WSASend/WSARecv directly on windows, hoping that this
100 works in all cases (unlike read/write/send/recv...).
101 - try to detect signals around a fork faster (test program by
102 Denis Bilenko).
103 - work around recent glibc versions that leak memory in realloc.
104 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
105 the watcher base set (loop) method.
106 - rewrite the async/signal pipe logic to always keep a valid fd, which
107 simplifies (and hopefully correctifies :) the race checking
108 on fork, at the cost of one extra fd.
109 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
110 inotify-supporting filesystems.
111 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
112 versions ignore it before
113 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
114 - add some untested android support.
115 - enum expressions must be of type int (reported by Juan Pablo L).
