7 | 4.29 |
|
|
8 | - (libev) add io uring autoconf and non-autoconf detection, |
|
|
9 | the latter of which should disable io_uring compilation |
|
|
10 | on old systems. |
|
|
11 | |

|
|
13 | - linuxaio backend resulted in random memory corruption |
|
|
14 | when loop is forked. |
|
|
15 | - linuxaio backend might have tried to cancel an iocb |
|
|
16 | multiple times (was unable to trigger this). |
|
|
17 | - linuxaio backend now employs a generation counter to |
|
|
18 | avoid handling spurious events from cancelled requests. |
|
|
19 | - io_cancel can return EINTR, deal with it. also, assume |
|
|
20 | io_submit also returns EINTR. |
|
|
21 | - fix some other minor bugs in linuxaio backend. |
|
|
22 | - ev_tstamp type can now be overriden by defining EV_TSTAMP_T. |
|
|
23 | - cleanup: replace expect_true/false and noinline by their |
|
|
24 | libecb counterparts. |
|
|
25 | - move syscall infrastructure from ev_linuxaio.c to ev.c. |
|
|
26 | - prepare io_uring integration. |
|
|
27 | - tweak ev_floor. |
|
|
28 | - epoll, poll, win32 Sleep and other places that use millisecond |
|
|
29 | reslution now all try to round up times. |
|
|
30 | - solaris port backend didn't compile. |
|
|
31 | - abstract time constants into their macros, for more flexibility. |
|

33 | 4.27 Thu Jun 27 22:43:44 CEST 2019 |
|
|
34 | - linux aio backend almost completely rewritten to work around its |
|
|
35 | limitations. |
|
|
36 | - linux aio backend now requires linux 4.19+. |
|
|
37 | - epoll backend now mandatory for linux aio backend. |
|
|
38 | - fail assertions more aggressively on invalid fd's detected |
|
|
39 | in the event loop, do not just silently fd_kill in case of |
|
|
40 | user error. |
|
|
41 | - ev_io_start/ev_io_stop now verify the watcher fd using |
|
|
42 | a syscall when EV_VERIFY is 2 or higher. |
|
|
43 | |
|
|
44 | 4.26 (EV only) |
|
|
45 | - update to libecb 0x00010006. |
|
|
46 | - new experimental linux aio backend (linux 4.18+). |
|
|
47 | - removed redundant 0-ptr check in ev_once. |
|
|
48 | - updated/extended ev_set_allocator documentation. |
|
|
49 | - replaced EMPTY2 macro by array_needsize_noinit. |
|
|
50 | - minor code cleanups. |
|
|
51 | - epoll backend now uses epoll_create1 also after fork. |
