|
|
4 | - fix a bug where an inotify watcher was added twice, causing |
|
|
5 | freezes on hash collisions (reported and analysed by Graham Leggett). |
|
|
6 | - new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use |
|
|
7 | a direct syscall - slower, but no dependency on librt et al. |
|
|
8 | - assume negative return values != -1 signals success of port_getn |
|
|
9 | (http://cvs.epicsol.org/cgi/viewcvs.cgi/epic5/source/newio.c?rev=1.52) |
|
|
10 | (no known failure reports, but it doesn't hurt). |
|
|
11 | - fork detection in ev_embed now stops and restarts the watcher |
|
|
12 | automatically. |
|
|
13 | - EXPERIMENTAL: default the method to operator () in ev++.h, |
|
|
14 | to make it nicer to use functors (requested by Benedek László). |
|
|
15 | - fixed const object callbacks in ev++.h. |
|
|
16 | - replaced loop_ref argument of watcher.set (loop) by a direct |
|
|
17 | ev_loop * in ev++.h, to avoid clashes with functor patch. |
|
|
18 | - do not try to watch the empty string via inotify. |
|
|
19 | - inotify watchers could be leaked under certain circumstances. |
|
|
20 | - OS X 10.5 is actually even more broken than earlier versions, |
|
|
21 | so fall back to select on that piece of garbage. |
|
|
22 | - fixed some weirdness in the ev_embed documentation. |

24 | 3.49 Wed Nov 19 11:26:53 CET 2008 |
|
|
25 | - ev_stat watchers will now use inotify as a mere hint on |
|
|
26 | kernels <2.6.25, or if the filesystem is not in the |
|
|
27 | "known to be good" list. |
|
|
28 | - better mingw32 compatibility (it's not as borked as native win32) |
|
|
29 | (analysed by Roger Pack). |
|
|
30 | - include stdio.h in the example program, as too many people are |
|
|
31 | confused by the weird C language otherwise. I guess the next thing |
|
|
32 | I get told is that the "..." ellipses in the examples don't compile |
|
|
33 | with their C compiler. |
