|
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. |

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. |

| 8 | - (libev) add io uring autoconf and non-autoconf detection, |
32 | - add io uring autoconf and non-autoconf detection. |
| 9 | the latter of which should disable io_uring compilation |
33 | - disable io_uring when some header files are too old. |
| 10 | on old systems. |
