| 3 | TODO: revisit 59.x timer in the light of mdoenr powersaving |
3 | TODO: for next ABI/API change, consider moving EV__IOFDSSET into io->fd instead and provide a getter. |
| 4 | TODO: maybe use timerfd to detect time jumps on linux |

|
|
6 | - the 4.31 timerfd code wrongly changes the priority of the signal |
|
|
7 | fd watcher, which is usually harmless unless signal fds are |
|
|
8 | also used (found via cpan tester service). |
|
|
9 | - the documentation wrongly claimed that user may modify fd and events |
|
|
10 | members in io watchers when the watcher was stopped |
|
|
11 | (found by b_jonas). |
|
|
12 | - new ev_io_modify mutator which changes only the events member, |
|
|
13 | which can be faster. also added ev::io::set (int events) method |
|
|
14 | to ev++.h. |
|
|
15 | - officially allow a zero events mask for io watchers. this should |
|
|
16 | work with older libev versions as well but was not officially |
|
|
17 | allowed before. |
|
|
18 | - do not wake up every minute when timerfd is used to detect timejumps. |
|
|
19 | - do not wake up every minute when periodics are disabled and we have |
|
|
20 | a monotonic clock. |
|
|
21 | - support a lot more "uncommon" compile time configurations, |
|
|
22 | such as ev_embed enabled but ev_timer disabled. |
|
|
23 | - use a start/stop wrapper class to reduce code duplication in |
|
|
24 | ev++.h and make it needlessly more c++-y. |
|
|
25 | - the linux aio backend is no longer compiled in by default. |
|
|
26 | - update to libecb version 0x00010008. |

|
|
29 | - handle backends with minimum wait time a bit better by not |
|
|
30 | waiting in the presence of already-expired timers |
|
|
31 | (behaviour reported by Felipe Gasper). |
|
|
32 | - new feature: use timerfd to detect timejumps quickly, |
|
|
33 | can be disabled with the new EVFLAG_NOTIMERFD loop flag. |
|
|
34 | - document EV_USE_SIGNALFD feature macro. |
|

36 | 4.30 (EV only) |
|
|
37 | - change non-autoconf test for __kernel_rwf_t by testing |
|
|
38 | LINUX_VERSION_CODE, the most direct test I could find. |
|
|
39 | - fix a bug in the io_uring backend that polled the wrong |
|
|
40 | backend fd, causing it to not work in many cases. |
|
|
41 | |
|
|
42 | 4.29 (EV only) |
|
|
43 | - add io uring autoconf and non-autoconf detection. |
|
|
44 | - disable io_uring when some header files are too old. |
