|
|
8 | - fix a race where the workaround against the epoll fork bugs |
|
|
9 | caused signals to not be handled anymore. |
|
|
10 | - correct backend_fudge for most backends, and implement a windows |
|
|
11 | specific workaround to avoid looping because we call both |
|
|
12 | select and Sleep, both with different time resolutions. |
|
|
13 | - document range and guarantees of ev_sleep. |
|
|
14 | - document reasonable ranges for periodics interval and offset. |
|
|
15 | - rename backend_fudge to backend_mintime to avoid future confusion :) |
|
|
16 | - change the default periodic reschedule function to hopefully be more |
|
|
17 | exact and correct even in corner cases or in the far future. |
|
|
18 | - do not rely on -lm anymore: use it when available but use our |
|
|
19 | own floor () if it is missing. This should make it easier to embed, |
|
|
20 | as no external libraries are required. |
|
|
21 | - strategically import macros from libecb and mark rarely-used functions |
|
|
22 | as cache-cold (saving almost 2k code size on typical amd64 setups). |
|
|
23 | - add Symbols.ev and Symbols.event files, that were missing. |
|
|
24 | |
|
|
25 | 4.04 Wed Feb 16 09:01:51 CET 2011 |
|
|
26 | - fix two problems in the native win32 backend, where reuse of fd's |
|
|
27 | with different underlying handles caused handles not to be removed |
|
|
28 | or added to the select set (analyzed and tested by Bert Belder). |
|
|
29 | - do no rely on ceil() in ev_e?poll.c. |
|
|
30 | - backport libev to HP-UX versions before 11 v3. |
|
|
31 | - configure did not detect nanosleep and clock_gettime properly when |
|
|
32 | they are available in the libc (as opposed to -lrt). |
|
|
33 | |
|
|
34 | 4.03 Tue Jan 11 14:37:25 CET 2011 |
|
|
35 | - officially support polling files with all backends. |
|
|
36 | - support files, /dev/zero etc. the same way as select in the epoll |
|
|
37 | backend, by generating events on our own. |
|
|
38 | - ports backend: work around solaris bug 6874410 and many related ones |
|
|
39 | (EINTR, maybe more), with no performance loss (note that the solaris |
|
|
40 | bug report is actually wrong, reality is far more bizarre and broken |
|
|
41 | than that). |
|
|
42 | - define EV_READ/EV_WRITE as macros in event.h, as some programs use |
|
|
43 | #ifdef to test for them. |
|
|
44 | - new (experimental) function: ev_feed_signal. |
|
|
45 | - new (to become default) EVFLAG_NOSIGMASK flag. |
|
|
46 | - new EVBACKEND_MASK symbol. |
|
|
47 | - updated COMMON IDIOMS SECTION. |
|
|
48 | |
|
|
49 | 4.01 Fri Nov 5 21:51:29 CET 2010 |
|
|
50 | - automake fucked it up, apparently, --add-missing -f is not quite enough |
|
|
51 | to make it update its files, so 4.00 didn't install ev++.h and |
|
|
52 | event.h on make install. grrr. |
|
|
53 | - ev_loop(count|depth) didn't return anything (Robin Haberkorn). |
|
|
54 | - change EV_UNDEF to 0xffffffff to silence some overzealous compilers. |
|
|
55 | - use "(libev) " prefix for all libev error messages now. |
|
|
56 | |
