3 | - linux aio backend almost complete rewritten to work around its |
| 4 | TODO: EV_STANDALONE == NO_HASSEL (do not use clock_gettime in ev_standalone) |
4 | limitations. |
| 5 | TODO: faq, process a thing in each iteration |
5 | - epoll backend now mandatory for linux aio backend. |
| 6 | TODO: dbeugging tips, ev_verify, ev_init twice |
6 | - fail assertions more aggressively on invalid fd's detected |
|
|
7 | in the event loop, do not just silently fd_kill in case of |
|
|
8 | user error. |
|
|
9 | - ev_io_start/ev_io_stop now verify the watcher fd using |
|
|
10 | a syscall when EV_VERIFY is 2 or higher. |

12 | 4.26 (EV only) |
|
|
13 | - update to libecb 0x00010006. |
|
|
14 | - new experimental linux aio backend (linux 4.18+). |
|
|
15 | - removed redundant 0-ptr check in ev_once. |
|
|
16 | - updated/extended ev_set_allocator documentation. |
|
|
17 | - replaced EMPTY2 macro by array_needsize_noinit. |
|
|
18 | - minor code cleanups. |
|
|
19 | - epoll backend now uses epoll_create1 also after fork. |
|
|
20 | |
|
|
21 | 4.25 Fri Dec 21 07:49:20 CET 2018 |
|
|
22 | - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT |
|
|
23 | (EV_THROW still provided) and now uses noexcept on C++11 or newer. |
|
|
24 | - move the darwin select workaround highe rin ev.c, as newer versions of |
|
|
25 | darwin managed to break their broken select even more. |
|
|
26 | - ANDROID => __ANDROID__ (reported by enh@google.com). |
|
|
27 | - disable epoll_create1 on android because it has broken header files |
|
|
28 | and google is unwilling to fix them (reported by enh@google.com). |
|
|
29 | - avoid a minor compilation warning on win32. |
|
|
30 | - c++: remove deprecated dynamic throw() specifications. |
|
|
31 | - c++: improve the (unsupported) bad_loop exception class. |
|
|
32 | - backport perl ev_periodic example to C, untested. |
|
|
33 | - update libecb, biggets change is to include a memory fence |
|
|
34 | in ECB_MEMORY_FENCE_RELEASE on x86/amd64. |
|
|
35 | - minor autoconf/automake modernisation. |
|
|
36 | |
|
|
37 | 4.24 Wed Dec 28 05:19:55 CET 2016 |
|
|
38 | - bump version to 4.24, as the release tarball inexplicably |
|
|
39 | didn't have the right version in ev.h, even though the cvs-tagged |
|
|
40 | version did have the right one (reported by Ales Teska). |
|
|
41 | |
|
|
42 | 4.23 Wed Nov 16 18:23:41 CET 2016 |
|
|
43 | - move some declarations at the beginning to help certain retarded |
|
|
44 | microsoft compilers, even though their documentation claims |
|
|
45 | otherwise (reported by Ruslan Osmanov). |
|
|
46 | |
|
|
47 | 4.22 Sun Dec 20 22:11:50 CET 2015 |
|
|
48 | - when epoll detects unremovable fds in the fd set, rebuild |
|
|
49 | only the epoll descriptor, not the signal pipe, to avoid |
|
|
50 | SIGPIPE in ev_async_send. This doesn't solve it on fork, |
|
|
51 | so document what needs to be done in ev_loop_fork |
|
|
52 | (analyzed by Benjamin Mahler). |
|
|
53 | - remove superfluous sys/timeb.h include on win32 |
|
|
54 | (analyzed by Jason Madden). |
|
|
55 | - updated libecb. |
|
|
56 | |
|
|
57 | 4.20 Sat Jun 20 13:01:43 CEST 2015 |
|
|
58 | - prefer noexcept over throw () with C++ 11. |
|
|
59 | - update ecb.h due to incompatibilities with c11. |
|
|
60 | - fix a potential aliasing issue when reading and writing |
|
|
61 | watcher callbacks. |
|
|
62 | |
|
|
63 | 4.19 Thu Sep 25 08:18:25 CEST 2014 |
|
|
64 | - ev.h wasn't valid C++ anymore, which tripped compilers other than |
|
|
65 | clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately, |
|
|
66 | C++ doesn't support typedefs for function pointers fully, so the affected |
|
|
67 | declarations have to spell out the types each time. |
|
|
68 | - when not using autoconf, tighten the check for clock_gettime and related |
|
|
69 | functionality. |
|
|
70 | |
|
|
71 | 4.18 Fri Sep 5 17:55:26 CEST 2014 |
|
|
72 | - events on files were not always generated properly with the |
|
|
73 | epoll backend (testcase by Assaf Inbal). |
|
|
74 | - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin). |
|
|
75 | - (ecb) support m68k, m88k and sh (patch by Miod Vallat). |
|
|
76 | - use a reasonable fallback for EV_NSIG instead of erroring out |
|
|
77 | when we can't detect the signal set size. |
|
|
78 | - in the absence of autoconf, do not use the clock syscall |
|
|
79 | on glibc >= 2.17 (avoids the syscall AND -lrt on systems |
|
|
80 | doing clock_gettime in userspace). |
|
|
81 | - ensure extern "C" function pointers are used for externally-visible |
|
|
82 | loop callbacks (not watcher callbacks yet). |
|
|
83 | - (ecb) work around memory barriers and volatile apparently both being |
|
|
84 | broken in visual studio 2008 and later (analysed and patch by Nicolas Noble). |
|

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