13 | 4.27 Thu Jun 27 22:43:44 CEST 2019 |
|
|
14 | - linux aio backend almost completely rewritten to work around its |
|
|
15 | limitations. |
|
|
16 | - linux aio backend now requires linux 4.19+. |
|
|
17 | - epoll backend now mandatory for linux aio backend. |
|
|
18 | - fail assertions more aggressively on invalid fd's detected |
|
|
19 | in the event loop, do not just silently fd_kill in case of |
|
|
20 | user error. |
|
|
21 | - ev_io_start/ev_io_stop now verify the watcher fd using |
|
|
22 | a syscall when EV_VERIFY is 2 or higher. |
|
|
23 | |
|
|
24 | 4.26 (EV only) |
|
|
25 | - update to libecb 0x00010006. |
|
|
26 | - new experimental linux aio backend (linux 4.18+). |
|
|
27 | - removed redundant 0-ptr check in ev_once. |
|
|
28 | - updated/extended ev_set_allocator documentation. |
|
|
29 | - replaced EMPTY2 macro by array_needsize_noinit. |
|
|
30 | - minor code cleanups. |
|
|
31 | - epoll backend now uses epoll_create1 also after fork. |
|
|
32 | |
|
|
33 | 4.25 Fri Dec 21 07:49:20 CET 2018 |
|
|
34 | - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT |
|
|
35 | (EV_THROW still provided) and now uses noexcept on C++11 or newer. |
|
|
36 | - move the darwin select workaround highe rin ev.c, as newer versions of |
|
|
37 | darwin managed to break their broken select even more. |
|
|
38 | - ANDROID => __ANDROID__ (reported by enh@google.com). |
|
|
39 | - disable epoll_create1 on android because it has broken header files |
|
|
40 | and google is unwilling to fix them (reported by enh@google.com). |
|
|
41 | - avoid a minor compilation warning on win32. |
|
|
42 | - c++: remove deprecated dynamic throw() specifications. |
|
|
43 | - c++: improve the (unsupported) bad_loop exception class. |
|
|
44 | - backport perl ev_periodic example to C, untested. |
|
|
45 | - update libecb, biggets change is to include a memory fence |
|
|
46 | in ECB_MEMORY_FENCE_RELEASE on x86/amd64. |
|
|
47 | - minor autoconf/automake modernisation. |
|
|
48 | |
|
|
49 | 4.24 Wed Dec 28 05:19:55 CET 2016 |
|
|
50 | - bump version to 4.24, as the release tarball inexplicably |
|
|
51 | didn't have the right version in ev.h, even though the cvs-tagged |
|
|
52 | version did have the right one (reported by Ales Teska). |
|
|
53 | |
|
|
54 | 4.23 Wed Nov 16 18:23:41 CET 2016 |
|
|
55 | - move some declarations at the beginning to help certain retarded |
|
|
56 | microsoft compilers, even though their documentation claims |
|
|
57 | otherwise (reported by Ruslan Osmanov). |
|
|
58 | |
|
|
59 | 4.22 Sun Dec 20 22:11:50 CET 2015 |
|
|
60 | - when epoll detects unremovable fds in the fd set, rebuild |
|
|
61 | only the epoll descriptor, not the signal pipe, to avoid |
|
|
62 | SIGPIPE in ev_async_send. This doesn't solve it on fork, |
|
|
63 | so document what needs to be done in ev_loop_fork |
|
|
64 | (analyzed by Benjamin Mahler). |
|
|
65 | - remove superfluous sys/timeb.h include on win32 |
|
|
66 | (analyzed by Jason Madden). |
|
|
67 | - updated libecb. |
|
|
68 | |
|
|
69 | 4.20 Sat Jun 20 13:01:43 CEST 2015 |
| 18 | - prefer noexcept over throw () with C++ 11. |
70 | - prefer noexcept over throw () with C++ 11. |
|
|
71 | - update ecb.h due to incompatibilities with c11. |
|
|
72 | - fix a potential aliasing issue when reading and writing |
|
|
73 | watcher callbacks. |
