2 2
3TODO: ev_loop_wakeup 3 - ANDROID => __ANDROID__ (reported by enh@google.com).
4 - disable epoll_create1 on android because it has broken header files
5 and google is unwilling to fix them (reported by enh@google.com).
4 6
5TODO: EV_NO_THREADS/NO_SMP and/or EV_USE_PTHREADS or so. also document. 74.24 Wed Dec 28 05:19:55 CET 2016
64.10 8 - bump version to 4.24, as the release tarball inexplicably
9 didn't have the right version in ev.h, even though the cvs-tagged
10 version did have the right one (reported by Ales Teska).
11
124.23 Wed Nov 16 18:23:41 CET 2016
13 - move some declarations at the beginning to help certain retarded
14 microsoft compilers, even though their documentation claims
15 otherwise (reported by Ruslan Osmanov).
16
174.22 Sun Dec 20 22:11:50 CET 2015
18 - when epoll detects unremovable fds in the fd set, rebuild
19 only the epoll descriptor, not the signal pipe, to avoid
20 SIGPIPE in ev_async_send. This doesn't solve it on fork,
21 so document what needs to be done in ev_loop_fork
22 (analyzed by Benjamin Mahler).
23 - remove superfluous sys/timeb.h include on win32
24 (analyzed by Jason Madden).
25 - updated libecb.
26
274.20 Sat Jun 20 13:01:43 CEST 2015
28 - prefer noexcept over throw () with C++ 11.
29 - update ecb.h due to incompatibilities with c11.
30 - fix a potential aliasing issue when reading and writing
31 watcher callbacks.
32
334.19 Thu Sep 25 08:18:25 CEST 2014
34 - ev.h wasn't valid C++ anymore, which tripped compilers other than
35 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
36 C++ doesn't support typedefs for function pointers fully, so the affected
37 declarations have to spell out the types each time.
38 - when not using autoconf, tighten the check for clock_gettime and related
39 functionality.
40
414.18 Fri Sep 5 17:55:26 CEST 2014
42 - events on files were not always generated properly with the
43 epoll backend (testcase by Assaf Inbal).
44 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
45 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
46 - use a reasonable fallback for EV_NSIG instead of erroring out
47 when we can't detect the signal set size.
48 - in the absence of autoconf, do not use the clock syscall
49 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
50 doing clock_gettime in userspace).
51 - ensure extern "C" function pointers are used for externally-visible
52 loop callbacks (not watcher callbacks yet).
53 - (ecb) work around memory barriers and volatile apparently both being
54 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
55
564.15 Fri Mar 1 12:04:50 CET 2013
57 - destroying a non-default loop would stop the global waitpid
58 watcher (Denis Bilenko).
59 - queueing pending watchers of higher priority from a watcher now invokes
60 them in a timely fashion (reported by Denis Bilenko).
61 - add throw() to all libev functions that cannot throw exceptions, for
62 further code size decrease when compiling for C++.
63 - add throw () to callbacks that must not throw exceptions (allocator,
64 syserr, loop acquire/release, periodic reschedule cbs).
65 - fix event_base_loop return code, add event_get_callback, event_base_new,
66 event_base_get_method calls to improve libevent 1.x emulation and add
67 some libevent 2.x functionality (based on a patch by Jeff Davey).
68 - add more memory fences to fix a bug reported by Jeff Davey. Better
69 be overfenced than underprotected.
70 - ev_run now returns a boolean status (true meaning watchers are
71 still active).
72 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
73 libev's EV_ERROR (reported by 191919).
74 - (ecb) add memory fence support for xlC (Darin McBride).
75 - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
76 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
77 - work around some kernels losing file descriptors by leaking
78 the kqueue descriptor in the child.
79 - work around linux inotify not reporting IN_ATTRIB changes for directories
80 in many cases.
81 - include sys/syscall.h instead of plain syscall.h.
82 - check for io watcher loops in ev_verify, check for the most
83 common reported usage bug in ev_io_start.
84 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
85 - always use WSASend/WSARecv directly on windows, hoping that this
86 works in all cases (unlike read/write/send/recv...).
87 - try to detect signals around a fork faster (test program by
88 Denis Bilenko).
89 - work around recent glibc versions that leak memory in realloc.
90 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
91 the watcher base set (loop) method.
92 - rewrite the async/signal pipe logic to always keep a valid fd, which
93 simplifies (and hopefully correctifies :) the race checking
94 on fork, at the cost of one extra fd.
95 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
96 inotify-supporting filesystems.
97 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
98 versions ignore it before
99 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
100 - add some untested android support.
101 - enum expressions must be of type int (reported by Juan Pablo L).

104 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
105 was documented already, but not implemented in the repeating case.
