1 Revision history for libev, a high-performance and full-featured event loop.
2
3 3.49 Wed Nov 19 11:26:53 CET 2008
4 - ev_stat watchers will now use inotify as a mere hint on
5 kernels <2.6.25, or if the filesystem is not in the
6 "known to be good" list.
7 - better mingw32 compatibility (it's not as borked as native win32)
8 (analysed by Roger Pack).
9 - include stdio.h in the example program, as too many people are
10 confused by the weird C language otherwise. I guess the next thing
11 I get told is that the "..." ellipses in the examples don't compile
12 with their C compiler.
13
14 3.48 Thu Oct 30 09:02:37 CET 2008
15 - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll
16 backend by assuming the kernel event mask hasn't changed if
17 ADD fails with EEXIST.
18 - work around spurious event notification bugs in epoll by using
19 a 32-bit generation counter. recreate kernel state if we receive
20 spurious notifications or unwanted events. this is very costly,
21 but I didn't come up with this horrible design.
22 - use memset to initialise most arrays now and do away with the
23 init functions.
24 - expand time-out strategies into a "Be smart about timeouts" section.
25 - drop the "struct" from all ev_watcher declarations in the
26 documentation and did other clarifications (yeah, it was a mistake
27 to have a struct AND a function called ev_loop).
28 - fix a bug where ev_default would not initialise the default
29 loop again after it was destroyed with ev_default_destroy.
30 - rename syserr to ev_syserr to avoid name clashes when embedding,
31 do similar changes for event.c.
32
33 3.45 Tue Oct 21 21:59:26 CEST 2008
34 - disable inotify usage on linux <2.6.25, as it is broken
35 (reported by Yoann Vandoorselaere).
36 - ev_stat errornously would try to add inotify watchers
37 even when inotify wasn't available (this should only
38 have a performance impact).
39 - ev_once now passes both timeout and io to the callback if both
40 occur concurrently, instead of giving timeouts precedence.
41 - disable EV_USE_INOTIFY when sys/inotify.h is too old.
42
43 3.44 Mon Sep 29 05:18:39 CEST 2008
44 - embed watchers now automatically invoke ev_loop_fork on the
45 embedded loop when the parent loop forks.
46 - new function: ev_now_update (loop).
47 - verify_watcher was not marked static.
48 - improve the "associating..." manpage section.
49 - documentation tweaks here and there.
50
51 3.43 Sun Jul 6 05:34:41 CEST 2008
52 - include more include files on windows to get struct _stati64
53 (reported by Chris Hulbert, but doesn't quite fix his issue).
54 - add missing #include <io.h> in ev.c on windows (reported by
55 Matt Tolton).
56
57 3.42 Tue Jun 17 12:12:07 CEST 2008
58 - work around yet another windows bug: FD_SET actually adds fd's
59 multiple times to the fd_*SET*, despite official MSN docs claiming
60 otherwise. Reported and well-analysed by Matt Tolton.
61 - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
62 (reported any analysed by Chris Hulbert).
63 - fix a bug in ev_ebadf (this function is only used to catch
64 programming errors in the libev user). reported by Matt Tolton.
65 - fix a bug in fd_intern on win32 (could lead to compile errors
66 under some circumstances, but would work correctly if it compiles).
67 reported by Matt Tolton.
68 - (try to) work around missing lstat on windows.
69 - pass in the write fd set as except fd set under windows. windows
70 is so uncontrollably lame that it requires this. this means that
71 switching off oobinline is not supported (but tcp/ip doesn't
72 have oob, so that would be stupid anyways.
73 - use posix module symbol to auto-detect monotonic clock presence
74 and some other default values.
75
76 3.41 Fri May 23 18:42:54 CEST 2008
77 - work around an obscure bug in winsocket select: if you
78 provide only empty fd sets then select returns WSAEINVAL. how sucky.
79 - improve timer scheduling stability and reduce use of time_epsilon.
80 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
81 codesize and makes for better cache-efficiency.
82 - use 3-based 4-heap for !EV_MINIMAL. this makes better use
83 of cpu cache lines and gives better growth behaviour than
84 2-based heaps.
85 - cache timestamp within heap for !EV_MINIMAL, to avoid random
86 memory accesses.
87 - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
88 - fix a potential aliasing issue in ev_timer_again.
89 - add/document ev_periodic_at, retract direct access to ->at.
90 - improve ev_stat docs.
91 - add portability requirements section.
92 - fix manpage headers etc.
93 - normalise WSA error codes to lower range on windows.
94 - add consistency check code that can be called automatically
95 or on demand to check for internal structures (ev_loop_verify).
96
97 3.31 Wed Apr 16 20:45:04 CEST 2008
98 - added last minute fix for ev_poll.c by Brandon Black.
99
100 3.3 Wed Apr 16 19:04:10 CEST 2008
101 - event_base_loopexit should return 0 on success
102 (W.C.A. Wijngaards).
103 - added linux eventfd support.
104 - try to autodetect epoll and inotify support
105 by libc header version if not using autoconf.
106 - new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
107 - declare functions defined in ev.h as inline if
108 C99 or gcc are available.
109 - enable inlining with gcc versions 2 and 3.
110 - work around broken poll implementations potentially
111 not clearing revents field in ev_poll (Brandon Black)
112 (no such systems are known at this time).
113 - work around a bug in realloc on openbsd and darwin,
114 also makes the errornous valgrind complaints
115 go away (noted by various people).
116 - fix ev_async_pending, add c++ wrapper for ev_async
117 (based on patch sent by Johannes Deisenhofer.
118 - add sensible set method to ev::embed.
119 - made integer constants type int in ev.h.
120
121 3.2 Wed Apr 2 17:11:19 CEST 2008
122 - fix a 64 bit overflow issue in the select backend,
123 by using fd_mask instead of int for the mask.
124 - rename internal sighandler to avoid clash with very old perls.
125 - entering ev_loop will not clear the ONESHOT or NONBLOCKING
126 flags of any outer loops anymore.
127 - add ev_async_pending.
128
