|
|
8 | - the 4.31 timerfd code wrongly changes the priority of the signal |
|
|
9 | fd watcher, which is usually harmless unless signal fds are |
|
|
10 | also used (found via cpan tester service). |
|
|
11 | - do not wake up every minute when timerfd is used to detect timejumps. |
|
|
12 | - support a lot more "uncommon" compile time configurations, |
|
|
13 | such as ev_embed enabled but ev_timer disabled. |
|
|
14 | - the linux aio backend is no longer compiled in by default. |
|
|
15 | - update to libecb version 0x00010008. |

|
|
18 | - handle backends with minimum wait time a bit better by not |
|
|
19 | waiting in the presence of already-expired timers |
|
|
20 | (behaviour reported by Felipe Gasper). |
|
|
21 | - new feature: use timerfd to detect timejumps quickly, |
|
|
22 | can be disabled with the new EVFLAG_NOTIMERFD loop flag. |
|
|
23 | - document EV_USE_SIGNALFD feature macro. |
|
|
24 | |
|
|
25 | 4.30 (EV only) |
|
|
26 | - change non-autoconf test for __kernel_rwf_t by testing |
|
|
27 | LINUX_VERSION_CODE, the most direct test I could find. |
|
|
28 | - fix a bug in the io_uring backend that polled the wrong |
|
|
29 | backend fd, causing it to not work in many cases. |
|
|
30 | |
|
|
31 | 4.29 (EV only) |
|
|
32 | - add io uring autoconf and non-autoconf detection. |
|
|
33 | - disable io_uring when some header files are too old. |
|
|
34 | |
|
|
35 | 4.28 (EV only) |
|
|
36 | - linuxaio backend resulted in random memory corruption |
|
|
37 | when loop is forked. |
|
|
38 | - linuxaio backend might have tried to cancel an iocb |
|
|
39 | multiple times (was unable to trigger this). |
|
|
40 | - linuxaio backend now employs a generation counter to |
|
|
41 | avoid handling spurious events from cancelled requests. |
|
|
42 | - io_cancel can return EINTR, deal with it. also, assume |
|
|
43 | io_submit also returns EINTR. |
|
|
44 | - fix some other minor bugs in linuxaio backend. |
|
|
45 | - ev_tstamp type can now be overriden by defining EV_TSTAMP_T. |
|
|
46 | - cleanup: replace expect_true/false and noinline by their |
|
|
47 | libecb counterparts. |
|
|
48 | - move syscall infrastructure from ev_linuxaio.c to ev.c. |
|
|
49 | - prepare io_uring integration. |
|
|
50 | - tweak ev_floor. |
|
|
51 | - epoll, poll, win32 Sleep and other places that use millisecond |
|
|
52 | reslution now all try to round up times. |
|
|
53 | - solaris port backend didn't compile. |
|
|
54 | - abstract time constants into their macros, for more flexibility. |
