|
|
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. |

|
|
12 | - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading. |
|
|
13 | - ev_embed_stop did not correctly stop the watcher (very good |
|
|
14 | testcase by Vladimir Timofeev). |
|
|
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). |
| 3 | - applied win32 fixes by Michael Lenaghan. |
19 | - applied win32 fixes by Michael Lenaghan (also James Mansion). |
|
|
20 | - replace EV_MINIMAL by EV_FEATURES. |
|
|
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. |
| 4 | - 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. |
| 5 | - configure now prepends -O3, not appends it, so one can still |
36 | - configure now prepends -O3, not appends it, so one can still |
| 6 | override it. |
37 | override it. |
|
|
38 | - ev.pod: greatly expanded the portability section, added a porting |
|
|
39 | section, a description of watcher states and made lots of minor fixes. |
|
|
40 | - disable poll backend on AIX, the poll header spams the namespace |
|
|
41 | and it's not worth working around dead platforms (reported |
|
|
42 | and analyzed by Aivars Kalvans). |
|
|
43 | - improve header file compatibility of the standalone eventfd code |
|
|
44 | in an obscure case. |
|
|
45 | - implement EV_AVOID_STDIO option. |
|
|
46 | - do not use sscanf to parse linux version number (smaller, faster, |
|
|
47 | no sscanf dependency). |
|
|
48 | - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings. |
|
|
49 | - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs. |
|
|
50 | - add section on accept() problems to the manpage. |
|
|
51 | - rename EV_TIMEOUT to EV_TIMER. |
|
|
52 | - rename ev_loop_count/depth/verify/loop/unloop. |
|
|
53 | - remove ev_default_destroy and ev_default_fork. |
|
|
54 | - switch to two-digit minor version. |
|
|
55 | - work around an apparent gentoo compiler bug. |
|
|
56 | - define _DARWIN_UNLIMITED_SELECT. just so. |
|
|
57 | - use enum instead of #define for most constants. |
|
|
58 | - improve compatibility to older C++ compilers. |
|
|
59 | - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now |
|
|
60 | default arguments when compiled as C++. |
|
|
61 | - enable automake dependency tracking. |
|
|
62 | - ev_loop_new no longer leaks memory when loop creation failed. |
|
|
63 | - new ev_cleanup watcher type. |
