7 | - libev did not compile on systems lacking clock_gettime. |
| 8 | TODO: use TFD_TIMER_CANCEL_ON_SET to call periodics_reschedule, maybe? (must) |
8 | - due to a logic bug, timerfd availability did not always translate |
|
|
9 | into fewer wakeups - libev is now more aggressive in using |
|
|
10 | longer sleeps, even when timerfd is not in use. |

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