6 | - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading. |
| 7 | TODO: gotsig per-loop |
7 | - ev_embed_stop did not correctly stop the watcher (very good |
|
|
8 | testcase by Vladimir Timofeev). |
|
|
9 | - ev_run will now always update the current loop time - it errornously |
|
|
10 | didn't when idle watchers were active, causing timers not to fire. |
|
|
11 | - fix a bug where a timeout of zero caused the timer not to fire |
|
|
12 | in the libevent emulation (testcase by Péter Szabó). |
|
|
13 | - applied win32 fixes by Michael Lenaghan (also James Mansion). |
|
|
14 | - replace EV_MINIMAL by EV_FEATURES. |
|
|
15 | - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it |
|
|
16 | seems the former is *much* faster than the latter. |
|
|
17 | - reduce the number of spurious wake-ups with the ports backend. |
|
|
18 | - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu). |
|
|
19 | - do async init within ev_async_start, not ev_async_set, which avoids |
|
|
20 | an API quirk where the set function must be called in the C++ API |
|
|
21 | even when there is nothing to set. |
|
|
22 | - add (undocumented) EV_ENABLE when adding events with kqueue, |
|
|
23 | this might help with OS X, which seems to need it despite documenting |
|
|
24 | not to need it (helpfully pointed out by Tilghman Lesher). |
|
|
25 | - do not use poll by default on freebsd, it's broken (what isn't |
|
|
26 | on freebsd...). |
|
|
27 | - configure now prepends -O3, not appends it, so one can still |
|
|
28 | override it. |
|
|
29 | - greatly expanded the portability section. |
|
|
30 | - disable poll backend on AIX, the poll header spams the namespace |
|
|
31 | and it's not worth working around dead platforms (reported |
|
|
32 | and analyzed by Aivars Kalvans). |
|
|
33 | - improve header file compatibility of the standalone eventfd code |
|
|
34 | in an obscure case. |
|
|
35 | - implement EV_AVOID_STDIO option. |
|
|
36 | - do not use sscanf to parse linux version number (smaller, faster, |
|
|
37 | no sscanf dependency). |
|
|
38 | - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings. |
|
|
39 | - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs. |
|
|
40 | - add section on accept() problems to the manpage. |
|
|
41 | - rename EV_TIMEOUT to EV_TIMER. |
|
|
42 | - rename ev_loop_count/depth/verify. |
|
|
43 | - switch to two-digit minor version. |
|
|
44 | - work around an apparent gentoo compiler bug. |
|
|
45 | - define _DARWIN_UNLIMITED_SELECT. just so. |
|
|
46 | - use enum instead of #define for most constants. |
|
|
47 | - improve compatibility to older C++ compilers. |
|
|

|
|
50 | - signalfd is no longer used by default and has to be requested |
|
|
51 | explicitly - this means that easy to catch bugs become hard to |
|
|
52 | catch race conditions, but the users have spoken. |
|
|
53 | - point out the unspecified signal mask in the documentation, and |
|
|
54 | that this is a race condition regardless of EV_SIGNALFD. |
|
|
55 | - backport inotify code to C89. |
|
|
56 | - inotify file descriptors could leak into child processes. |
|
|
57 | - ev_stat watchers could keep an errornous extra ref on the loop, |
|
|
58 | preventing exit when unregistering all watchers (testcases |
|
|
59 | provided by ry@tinyclouds.org). |
|
|
60 | - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration |
|
|
61 | symbols to make it easier for apps to do their own fd management. |
|
|
62 | - support EV_IDLE_ENABLE being disabled in ev++.h |
|
|
63 | (patch by Didier Spezia). |
|
|
64 | - take advantage of inotify_init1, if available, to set cloexec/nonblock |
|
|
65 | on fd creation, to avoid races. |
|
|
66 | - the signal handling pipe wasn't always initialised under windows |
|
|
67 | (analysed by lekma). |
|
|
68 | - changed minimum glibc requirement from glibc 2.9 to 2.7, for |
|
|
69 | signalfd. |
|
|
70 | - add missing string.h include (Denis F. Latypoff). |
|
|
71 | - only replace ev_stat.prev when we detect an actual difference, |
|
|
72 | so prev is (almost) always different to attr. this might |
|
|
73 | have caused the probems with 04_stat.t. |
|
|
74 | - add ev::timer->remaining () method to C++ API. |
|
|
