4 | - automake fucked it up, apparently, --add-missing -f is not quite enough |
|
|
5 | to make it update its files, so 4.00 didn't install ev++.h and |
|
|
6 | event.h on make install. grrr. |
|
|
7 | - ev_loop(count|depth) didn't return anything (Robin Haberkorn). |
|
|
8 | - change EV_UNDEF to 0xffffffff to silence some overzealous compilers. |
|
|
9 | - use "(libev) " prefix for all libev error messages now. |

|
|
15 | - ev_run will now always update the current loop time - it erroneously |
|
|
16 | didn't when idle watchers were active, causing timers not to fire. |
|
|
17 | - fix a bug where a timeout of zero caused the timer not to fire |
|
|
18 | in the libevent emulation (testcase by Péter Szabó). |
8 | - applied win32 fixes by Michael Lenaghan (also James Mansion). |

|
|
21 | - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it |
|
|
22 | seems the former is *much* faster than the latter. |
|
|
23 | - linux kernel version detection (for inotify bug workarounds) |
|
|
24 | did not work properly. |
|
|
25 | - reduce the number of spurious wake-ups with the ports backend. |
10 | - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu). |
26 | - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu). |
|
|
27 | - do async init within ev_async_start, not ev_async_set, which avoids |
|
|
28 | an API quirk where the set function must be called in the C++ API |
|
|
29 | even when there is nothing to set. |
|
|
30 | - add (undocumented) EV_ENABLE when adding events with kqueue, |
|
|
31 | this might help with OS X, which seems to need it despite documenting |
|
|
32 | not to need it (helpfully pointed out by Tilghman Lesher). |
|
|
33 | - do not use poll by default on freebsd, it's broken (what isn't |
|
|
34 | on freebsd...). |
|
|
35 | - allow to embed epoll on kernels >= 2.6.32. |

|
|
38 | - ev.pod: greatly expanded the portability section, added a porting |
