|
|
7 | - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll |
|
|
8 | backend by assuming the kernel event mask hasn't changed if |
|
|
9 | ADD fails with EEXIST. |
|
|
10 | - work around spurious event notification bugs in epoll by using |
|
|
11 | a 32-bit generation counter. recreate kernel state if we receive |
|
|
12 | spurious notifications or unwanted events. this is very costly, |
|
|
13 | but I didn't come up with this horrible design. |
|
|
14 | - use memset to initialise most arrays now and do away with the |
|
|
15 | init functions. |
|
|
16 | - expand time-out strategies into a "Be smart about timeouts" section. |
|
|
17 | - drop the "struct" from all ev_watcher declarations in the |
|
|
18 | documentation and did other clarifications (yeah, it was a mistake |
|
|
19 | to have a struct AND a function called ev_loop). |
|
|
20 | - fix a bug where ev_default would not initialise the default |
|
|
21 | loop again after it was destroyed with ev_default_destroy. |
|
|
22 | - rename syserr to ev_syserr to avoid name clashes when embedding, |
|
|
23 | do similar changes for event.c. |
|
|

|
|
26 | - disable inotify usage on linux <2.6.25, as it is broken |
|
|
27 | (reported by Yoann Vandoorselaere). |
|
|
28 | - ev_stat errornously would try to add inotify watchers |
|
|
29 | even when inotify wasn't available (this should only |
|
|
30 | have a performance impact). |
|
|
31 | - ev_once now passes both timeout and io to the callback if both |
|
|
32 | occur concurrently, instead of giving timeouts precedence. |
|
|
33 | - disable EV_USE_INOTIFY when sys/inotify.h is too old. |
|
|
34 | |
|
|
35 | 3.44 Mon Sep 29 05:18:39 CEST 2008 |
|
|
36 | - embed watchers now automatically invoke ev_loop_fork on the |
|
|
37 | embedded loop when the parent loop forks. |
|
|
38 | - new function: ev_now_update (loop). |
|
|
39 | - verify_watcher was not marked static. |
|
|
40 | - improve the "associating..." manpage section. |
|
|
41 | - documentation tweaks here and there. |
|
|

|
|
44 | - include more include files on windows to get struct _stati64 |
|
|
45 | (reported by Chris Hulbert, but doesn't quite fix his issue). |
|
|
46 | - add missing #include <io.h> in ev.c on windows (reported by |
|
|
47 | Matt Tolton). |
|
|
48 | |
|
|
49 | 3.42 Tue Jun 17 12:12:07 CEST 2008 |
|
|
50 | - work around yet another windows bug: FD_SET actually adds fd's |
|
|
51 | multiple times to the fd_*SET*, despite official MSN docs claiming |
|
|
52 | otherwise. Reported and well-analysed by Matt Tolton. |
|
|
53 | - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile |
|
|
54 | (reported any analysed by Chris Hulbert). |
|
|
55 | - fix a bug in ev_ebadf (this function is only used to catch |
|
|
56 | programming errors in the libev user). reported by Matt Tolton. |
|
|
57 | - fix a bug in fd_intern on win32 (could lead to compile errors |
|
|
58 | under some circumstances, but would work correctly if it compiles). |
|
|
59 | reported by Matt Tolton. |
|
|
60 | - (try to) work around missing lstat on windows. |
|
|
61 | - pass in the write fd set as except fd set under windows. windows |
|
|
62 | is so uncontrollably lame that it requires this. this means that |
|
|
63 | switching off oobinline is not supported (but tcp/ip doesn't |
|
|
64 | have oob, so that would be stupid anyways. |
|
|
65 | - use posix module symbol to auto-detect monotonic clock presence |
|
|
66 | and some other default values. |
|
|
67 | |
|
|
68 | 3.41 Fri May 23 18:42:54 CEST 2008 |
|
|
69 | - work around an obscure bug in winsocket select: if you |
|
|
70 | provide only empty fd sets then select returns WSAEINVAL. how sucky. |
|
|
71 | - improve timer scheduling stability and reduce use of time_epsilon. |
| 4 | - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces |
72 | - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces |

74 | - use 3-based 4-heap for !EV_MINIMAL. this makes better use |
