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) 4 - linuxaio backend might have tried to cancel an iocb
5 multiple times (was unable to trigger this).
6 - io_cancel can return EINTR, deal with it. also, assume
7 io_asubmit also retursn EINTR.
5 8
6TODO: document WSA_EV_USE_SOCKET in win32 part 94.27 Thu Jun 27 22:43:44 CEST 2019
7TODO: ^ OR use WSASend/WSARecv on the handle, which always works 10 - linux aio backend almost completely rewritten to work around its
8TODO: use __OPTIMIZE__ or __OPTIMIZE_SIZE__? 11 limitations.
12 - linux aio backend now requires linux 4.19+.
13 - epoll backend now mandatory for linux aio backend.
14 - fail assertions more aggressively on invalid fd's detected
15 in the event loop, do not just silently fd_kill in case of
16 user error.
17 - ev_io_start/ev_io_stop now verify the watcher fd using
18 a syscall when EV_VERIFY is 2 or higher.
19
204.26 (EV only)
21 - update to libecb 0x00010006.
22 - new experimental linux aio backend (linux 4.18+).
23 - removed redundant 0-ptr check in ev_once.
24 - updated/extended ev_set_allocator documentation.
25 - replaced EMPTY2 macro by array_needsize_noinit.
26 - minor code cleanups.
27 - epoll backend now uses epoll_create1 also after fork.
28
294.25 Fri Dec 21 07:49:20 CET 2018
30 - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
31 (EV_THROW still provided) and now uses noexcept on C++11 or newer.
32 - move the darwin select workaround highe rin ev.c, as newer versions of
33 darwin managed to break their broken select even more.
34 - ANDROID => __ANDROID__ (reported by enh@google.com).
35 - disable epoll_create1 on android because it has broken header files
36 and google is unwilling to fix them (reported by enh@google.com).
37 - avoid a minor compilation warning on win32.
38 - c++: remove deprecated dynamic throw() specifications.
39 - c++: improve the (unsupported) bad_loop exception class.
40 - backport perl ev_periodic example to C, untested.
41 - update libecb, biggets change is to include a memory fence
42 in ECB_MEMORY_FENCE_RELEASE on x86/amd64.
43 - minor autoconf/automake modernisation.
44
454.24 Wed Dec 28 05:19:55 CET 2016
46 - bump version to 4.24, as the release tarball inexplicably
47 didn't have the right version in ev.h, even though the cvs-tagged
48 version did have the right one (reported by Ales Teska).
49
504.23 Wed Nov 16 18:23:41 CET 2016
51 - move some declarations at the beginning to help certain retarded
52 microsoft compilers, even though their documentation claims
53 otherwise (reported by Ruslan Osmanov).
54
554.22 Sun Dec 20 22:11:50 CET 2015
56 - when epoll detects unremovable fds in the fd set, rebuild
57 only the epoll descriptor, not the signal pipe, to avoid
58 SIGPIPE in ev_async_send. This doesn't solve it on fork,
59 so document what needs to be done in ev_loop_fork
60 (analyzed by Benjamin Mahler).
61 - remove superfluous sys/timeb.h include on win32
62 (analyzed by Jason Madden).
63 - updated libecb.
64
654.20 Sat Jun 20 13:01:43 CEST 2015
66 - prefer noexcept over throw () with C++ 11.
67 - update ecb.h due to incompatibilities with c11.
68 - fix a potential aliasing issue when reading and writing
69 watcher callbacks.
70
714.19 Thu Sep 25 08:18:25 CEST 2014
72 - ev.h wasn't valid C++ anymore, which tripped compilers other than
73 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
74 C++ doesn't support typedefs for function pointers fully, so the affected
75 declarations have to spell out the types each time.
76 - when not using autoconf, tighten the check for clock_gettime and related
77 functionality.
78
794.18 Fri Sep 5 17:55:26 CEST 2014
80 - events on files were not always generated properly with the
81 epoll backend (testcase by Assaf Inbal).
82 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
83 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
84 - use a reasonable fallback for EV_NSIG instead of erroring out
85 when we can't detect the signal set size.
86 - in the absence of autoconf, do not use the clock syscall
87 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
88 doing clock_gettime in userspace).
89 - ensure extern "C" function pointers are used for externally-visible
90 loop callbacks (not watcher callbacks yet).
91 - (ecb) work around memory barriers and volatile apparently both being
92 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
93
944.15 Fri Mar 1 12:04:50 CET 2013
95 - destroying a non-default loop would stop the global waitpid
96 watcher (Denis Bilenko).
97 - queueing pending watchers of higher priority from a watcher now invokes
98 them in a timely fashion (reported by Denis Bilenko).
99 - add throw() to all libev functions that cannot throw exceptions, for
100 further code size decrease when compiling for C++.
101 - add throw () to callbacks that must not throw exceptions (allocator,
102 syserr, loop acquire/release, periodic reschedule cbs).
103 - fix event_base_loop return code, add event_get_callback, event_base_new,
104 event_base_get_method calls to improve libevent 1.x emulation and add
105 some libevent 2.x functionality (based on a patch by Jeff Davey).
106 - add more memory fences to fix a bug reported by Jeff Davey. Better
107 be overfenced than underprotected.
108 - ev_run now returns a boolean status (true meaning watchers are
109 still active).
9 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with 110 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
10 libev's EV_ERROR (reported by 191919). 111 libev's EV_ERROR (reported by 191919).
11
12TODO: Jeff Davey libev patch
13 - (ecb) add memory fence support for xlC (Darin McBride). 112 - (ecb) add memory fence support for xlC (Darin McBride).
14 - (ecb) add memory fence support for gcc-mips (Anton Kirilov). 113 - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
114 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
115 - work around some kernels losing file descriptors by leaking
116 the kqueue descriptor in the child.
117 - work around linux inotify not reporting IN_ATTRIB changes for directories
118 in many cases.
119 - include sys/syscall.h instead of plain syscall.h.
120 - check for io watcher loops in ev_verify, check for the most
121 common reported usage bug in ev_io_start.
122 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
123 - always use WSASend/WSARecv directly on windows, hoping that this
124 works in all cases (unlike read/write/send/recv...).
125 - try to detect signals around a fork faster (test program by
126 Denis Bilenko).
127 - work around recent glibc versions that leak memory in realloc.
128 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
129 the watcher base set (loop) method.
130 - rewrite the async/signal pipe logic to always keep a valid fd, which
131 simplifies (and hopefully correctifies :) the race checking
132 on fork, at the cost of one extra fd.
133 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
134 inotify-supporting filesystems.
135 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
136 versions ignore it before
137 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
138 - add some untested android support.
139 - enum expressions must be of type int (reported by Juan Pablo L).
