|
7 | - no changes w.r.t. 4.32. |
|

|
|
9 | 4.32 (EV only) |
|
|
10 | - the 4.31 timerfd code wrongly changed the priority of the signal |
|
|
11 | fd watcher, which is usually harmless unless signal fds are |
|
|
12 | also used (found via cpan tester service). |
|
|
13 | - the documentation wrongly claimed that user may modify fd and events |
|
|
14 | members in io watchers when the watcher was stopped |
|
|
15 | (found by b_jonas). |
|
|
16 | - new ev_io_modify mutator which changes only the events member, |
|
|
17 | which can be faster. also added ev::io::set (int events) method |
|
|
18 | to ev++.h. |
|
|
19 | - officially allow a zero events mask for io watchers. this should |
|
|
20 | work with older libev versions as well but was not officially |
|
|
21 | allowed before. |
|
|
22 | - do not wake up every minute when timerfd is used to detect timejumps. |
|
|
23 | - do not wake up every minute when periodics are disabled and we have |
|
|
24 | a monotonic clock. |
|
|
25 | - support a lot more "uncommon" compile time configurations, |
|
|
26 | such as ev_embed enabled but ev_timer disabled. |
|
|
27 | - use a start/stop wrapper class to reduce code duplication in |
|
|
28 | ev++.h and make it needlessly more c++-y. |
|
|
29 | - the linux aio backend is no longer compiled in by default. |
|
|
30 | - update to libecb version 0x00010008. |
|

36 | - new feature: use timerfd to detect timejumps quickly, |
|
|
37 | can be disabled with the new EVFLAG_NOTIMERFD loop flag. |
