5 | - change the default periodic reschedule function to hopefully be more |
|
|
6 | exact and correct even in corner cases or in the far future. |
|
|
7 | - document reasonable ranges for interval and offset. |
|
|
8 | - do not rely on -lm anymore: use it when available but use our |
|
|
9 | own floor () if it is missing. This should make it easier to embed. |

11 | 4.04 Wed Feb 16 09:01:51 CET 2011 |
|
|
12 | - fix two problems in the native win32 backend, where reuse of fd's |
|
|
13 | with different underlying handles caused handles not to be removed |
|
|
14 | or added to the select set (analyzed and tested by Bert Belder). |
|
|
15 | - do no rely on ceil() in ev_e?poll.c. |
|
|
16 | - backport libev to HP-UX versions before 11 v3. |
|
|
17 | - configure did not detect nanosleep and clock_gettime properly when |
|
|
18 | they are available in the libc (as opposed to -lrt). |
|

|
|
21 | - officially support polling files with all backends. |
|
|
22 | - support files, /dev/zero etc. the same way as select in the epoll |
|
|
23 | backend, by generating events on our own. |
|
|
24 | - ports backend: work around solaris bug 6874410 and many related ones |
|
|
25 | (EINTR, maybe more), with no performance loss (note that the solaris |
|
|
26 | bug report is actually wrong, reality is far more bizarre and broken |
|
|
27 | than that). |
|
|
28 | - define EV_READ/EV_WRITE as macros in event.h, as some programs use |
|
|
29 | #ifdef to test for them. |
|
|
30 | - new (experimental) function: ev_feed_signal. |
|
|
31 | - new (to become default) EVFLAG_NOSIGMASK flag. |
|
|
32 | - new EVBACKEND_MASK symbol. |
|
|
33 | - updated COMMON IDIOMS SECTION. |

35 | 4.01 Fri Nov 5 21:51:29 CET 2010 |
|
|
36 | - automake fucked it up, apparently, --add-missing -f is not quite enough |
|
|
37 | to make it update its files, so 4.00 didn't install ev++.h and |
|
|
38 | event.h on make install. grrr. |
|
|
39 | - ev_loop(count|depth) didn't return anything (Robin Haberkorn). |
|
|
40 | - change EV_UNDEF to 0xffffffff to silence some overzealous compilers. |
|
|
41 | - use "(libev) " prefix for all libev error messages now. |
|
|
