2 2
3TODO: ev_loop_wakeup 3TODO: revisit 59.x timer in the light of mdoenr powersaving
4TODO: EV_STANDALONE == NO_HASSEL (do not use clock_gettime in ev_standalone) 44.27 (EV only)
5TODO: faq, process a thing in each iteration 5 - linux aio backend almost complete rewritten to work around its
6TODO: dbeugging tips, ev_verify, ev_init twice 6 limitations.
7 - epoll backend now mandatory for linux aio backend.
8 - fail assertions more aggressively on invalid fd's detected
9 in the event loop, do not just silently fd_kill in case of
10 user error.
11 - ev_io_start/ev_io_stop now verify the watcher fd using
12 a syscall when EV_VERIFY is 2 or higher.
7 13
144.26 (EV only)
15 - update to libecb 0x00010006.
16 - new experimental linux aio backend (linux 4.18+).
17 - removed redundant 0-ptr check in ev_once.
18 - updated/extended ev_set_allocator documentation.
19 - replaced EMPTY2 macro by array_needsize_noinit.
20 - minor code cleanups.
21 - epoll backend now uses epoll_create1 also after fork.
22
234.25 Fri Dec 21 07:49:20 CET 2018
24 - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
25 (EV_THROW still provided) and now uses noexcept on C++11 or newer.
26 - move the darwin select workaround highe rin ev.c, as newer versions of
27 darwin managed to break their broken select even more.
28 - ANDROID => __ANDROID__ (reported by enh@google.com).
29 - disable epoll_create1 on android because it has broken header files
30 and google is unwilling to fix them (reported by enh@google.com).
31 - avoid a minor compilation warning on win32.
32 - c++: remove deprecated dynamic throw() specifications.
33 - c++: improve the (unsupported) bad_loop exception class.
34 - backport perl ev_periodic example to C, untested.
35 - update libecb, biggets change is to include a memory fence
36 in ECB_MEMORY_FENCE_RELEASE on x86/amd64.
37 - minor autoconf/automake modernisation.
38
394.24 Wed Dec 28 05:19:55 CET 2016
40 - bump version to 4.24, as the release tarball inexplicably
41 didn't have the right version in ev.h, even though the cvs-tagged
42 version did have the right one (reported by Ales Teska).
43
444.23 Wed Nov 16 18:23:41 CET 2016
45 - move some declarations at the beginning to help certain retarded
46 microsoft compilers, even though their documentation claims
47 otherwise (reported by Ruslan Osmanov).
48
494.22 Sun Dec 20 22:11:50 CET 2015
50 - when epoll detects unremovable fds in the fd set, rebuild
51 only the epoll descriptor, not the signal pipe, to avoid
52 SIGPIPE in ev_async_send. This doesn't solve it on fork,
53 so document what needs to be done in ev_loop_fork
54 (analyzed by Benjamin Mahler).
55 - remove superfluous sys/timeb.h include on win32
56 (analyzed by Jason Madden).
57 - updated libecb.
58
594.20 Sat Jun 20 13:01:43 CEST 2015
60 - prefer noexcept over throw () with C++ 11.
61 - update ecb.h due to incompatibilities with c11.
62 - fix a potential aliasing issue when reading and writing
63 watcher callbacks.
64
654.19 Thu Sep 25 08:18:25 CEST 2014
66 - ev.h wasn't valid C++ anymore, which tripped compilers other than
67 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
68 C++ doesn't support typedefs for function pointers fully, so the affected
69 declarations have to spell out the types each time.
70 - when not using autoconf, tighten the check for clock_gettime and related
71 functionality.
72
734.18 Fri Sep 5 17:55:26 CEST 2014
74 - events on files were not always generated properly with the
75 epoll backend (testcase by Assaf Inbal).
76 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
77 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
78 - use a reasonable fallback for EV_NSIG instead of erroring out
79 when we can't detect the signal set size.
80 - in the absence of autoconf, do not use the clock syscall
81 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
82 doing clock_gettime in userspace).
83 - ensure extern "C" function pointers are used for externally-visible
84 loop callbacks (not watcher callbacks yet).
85 - (ecb) work around memory barriers and volatile apparently both being
86 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).

90 watcher (Denis Bilenko).

14 - fix event_base_loop return code, add event_get_callback, event_base_new, 97 - 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 98 event_base_get_method calls to improve libevent 1.x emulation and add

119 - try to detect signals around a fork faster (test program by
120 Denis Bilenko).
121 - work around recent glibc versions that leak memory in realloc.
122 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
123 the watcher base set (loop) method.
124 - rewrite the async/signal pipe logic to always keep a valid fd, which
125 simplifies (and hopefully correctifies :) the race checking
126 on fork, at the cost of one extra fd.
127 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
128 inotify-supporting filesystems.
129 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
130 versions ignore it before
131 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
132 - add some untested android support.
133 - enum expressions must be of type int (reported by Juan Pablo L).
