9 | - support files, /dev/zero etc. the same way as select in the epoll |
|
|
10 | backend, by generating events on our own. |
|
|
11 | - define EV_READ/EV_WRITE as macros in event.h, as some programs use |
|
|
12 | #ifdef to test for them. |
|
|
13 | - new (experimental) function: ev_feed_signal. |
|
|
14 | - new (to become default) EVFLAG_NOSIGMASK flag. |
|
|
15 | - new EVBACKEND_MASK symbol. |
|
|
16 | - ports backend: work around solaris bug 6874410 and many related ones |

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