3 - move the darwin select workaround highe rin ev.c, as newre versions of
4 darwin managed to break their broken select even more.
5 - ANDROID => __ANDROID__ (reported by enh@google.com).
6 - disable epoll_create1 on android because it has broken header files
7 and google is unwilling to fix them (reported by enh@google.com).
8 - avoid a minor compilation warning on win32.
9 - c++: rename EV_THROW to EV_NOEXCEPT
10 - c++: remove deprecated dynamic throw() specifications.
11 - c++: improve the (unsupported) bad_loop exception class.
12
134.24 Wed Dec 28 05:19:55 CET 2016
14 - bump version to 4.24, as the release tarball inexplicably
15 didn't have the right version in ev.h, even though the cvs-tagged
16 version did have the right one (reported by Ales Teska).
17
184.23 Wed Nov 16 18:23:41 CET 2016
19 - move some declarations at the beginning to help certain retarded
20 microsoft compilers, even though their documentation claims
21 otherwise (reported by Ruslan Osmanov).
22
234.22 Sun Dec 20 22:11:50 CET 2015
24 - when epoll detects unremovable fds in the fd set, rebuild
25 only the epoll descriptor, not the signal pipe, to avoid
26 SIGPIPE in ev_async_send. This doesn't solve it on fork,
27 so document what needs to be done in ev_loop_fork
28 (analyzed by Benjamin Mahler).
29 - remove superfluous sys/timeb.h include on win32
30 (analyzed by Jason Madden).
31 - updated libecb.
32
334.20 Sat Jun 20 13:01:43 CEST 2015
34 - prefer noexcept over throw () with C++ 11.
35 - update ecb.h due to incompatibilities with c11.
36 - fix a potential aliasing issue when reading and writing
37 watcher callbacks.
38
394.19 Thu Sep 25 08:18:25 CEST 2014
40 - ev.h wasn't valid C++ anymore, which tripped compilers other than
41 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
42 C++ doesn't support typedefs for function pointers fully, so the affected
43 declarations have to spell out the types each time.
44 - when not using autoconf, tighten the check for clock_gettime and related
45 functionality.
46
474.18 Fri Sep 5 17:55:26 CEST 2014
48 - events on files were not always generated properly with the
49 epoll backend (testcase by Assaf Inbal).
50 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
51 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
52 - use a reasonable fallback for EV_NSIG instead of erroring out
53 when we can't detect the signal set size.
54 - in the absence of autoconf, do not use the clock syscall
55 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
56 doing clock_gettime in userspace).
57 - ensure extern "C" function pointers are used for externally-visible
58 loop callbacks (not watcher callbacks yet).
59 - (ecb) work around memory barriers and volatile apparently both being
60 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
61
624.15 Fri Mar 1 12:04:50 CET 2013
63 - destroying a non-default loop would stop the global waitpid
64 watcher (Denis Bilenko).
65 - queueing pending watchers of higher priority from a watcher now invokes
66 them in a timely fashion (reported by Denis Bilenko).
67 - add throw() to all libev functions that cannot throw exceptions, for
68 further code size decrease when compiling for C++.
69 - add throw () to callbacks that must not throw exceptions (allocator,
70 syserr, loop acquire/release, periodic reschedule cbs).
71 - fix event_base_loop return code, add event_get_callback, event_base_new,
72 event_base_get_method calls to improve libevent 1.x emulation and add
73 some libevent 2.x functionality (based on a patch by Jeff Davey).
74 - add more memory fences to fix a bug reported by Jeff Davey. Better
75 be overfenced than underprotected.
76 - ev_run now returns a boolean status (true meaning watchers are
77 still active).
78 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
79 libev's EV_ERROR (reported by 191919).
80 - (ecb) add memory fence support for xlC (Darin McBride).
81 - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
82 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
83 - work around some kernels losing file descriptors by leaking
84 the kqueue descriptor in the child.
85 - work around linux inotify not reporting IN_ATTRIB changes for directories
86 in many cases.
87 - include sys/syscall.h instead of plain syscall.h.
88 - check for io watcher loops in ev_verify, check for the most
89 common reported usage bug in ev_io_start.
90 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
91 - always use WSASend/WSARecv directly on windows, hoping that this
92 works in all cases (unlike read/write/send/recv...).
93 - try to detect signals around a fork faster (test program by
94 Denis Bilenko).
95 - work around recent glibc versions that leak memory in realloc.
96 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
97 the watcher base set (loop) method.
98 - rewrite the async/signal pipe logic to always keep a valid fd, which
99 simplifies (and hopefully correctifies :) the race checking
100 on fork, at the cost of one extra fd.
101 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
102 inotify-supporting filesystems.
103 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
104 versions ignore it before
105 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
106 - add some untested android support.
107 - enum expressions must be of type int (reported by Juan Pablo L).
108
1094.11 Sat Feb 4 19:52:39 CET 2012
110 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
111 was documented already, but not implemented in the repeating case.
112 - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
113 - fix a race where the workaround against the epoll fork bugs
114 caused signals to not be handled anymore.
115 - correct backend_fudge for most backends, and implement a windows
116 specific workaround to avoid looping because we call both
117 select and Sleep, both with different time resolutions.
118 - document range and guarantees of ev_sleep.
119 - document reasonable ranges for periodics interval and offset.
120 - rename backend_fudge to backend_mintime to avoid future confusion :)
121 - change the default periodic reschedule function to hopefully be more
122 exact and correct even in corner cases or in the far future.
123 - do not rely on -lm anymore: use it when available but use our
124 own floor () if it is missing. This should make it easier to embed,
125 as no external libraries are required.
126 - strategically import macros from libecb and mark rarely-used functions
127 as cache-cold (saving almost 2k code size on typical amd64 setups).
128 - add Symbols.ev and Symbols.event files, that were missing.
129 - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
130 - fix #3 "be smart about timeouts" to not "deadlock" when
131 timeout == now, also improve the section overall.
132 - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
133 - support new EV_API_STATIC mode to make all libev symbols
134 static.
135 - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
136 were empty.
137
1384.04 Wed Feb 16 09:01:51 CET 2011
139 - fix two problems in the native win32 backend, where reuse of fd's
140 with different underlying handles caused handles not to be removed
141 or added to the select set (analyzed and tested by Bert Belder).
142 - do no rely on ceil() in ev_e?poll.c.
143 - backport libev to HP-UX versions before 11 v3.
144 - configure did not detect nanosleep and clock_gettime properly when
145 they are available in the libc (as opposed to -lrt).
146
1474.03 Tue Jan 11 14:37:25 CET 2011
148 - officially support polling files with all backends.
149 - support files, /dev/zero etc. the same way as select in the epoll
150 backend, by generating events on our own.
151 - ports backend: work around solaris bug 6874410 and many related ones
152 (EINTR, maybe more), with no performance loss (note that the solaris
153 bug report is actually wrong, reality is far more bizarre and broken
154 than that).
155 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
156 #ifdef to test for them.
157 - new (experimental) function: ev_feed_signal.
158 - new (to become default) EVFLAG_NOSIGMASK flag.
159 - new EVBACKEND_MASK symbol.
160 - updated COMMON IDIOMS SECTION.
