# Content
1 Revision history for libev, a high-performance and full-featured event loop.
2
3 WISH? monotonic clocks times/GetTickCount for coarse corrections?
4
5 - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll
6 backend by assuming the kernel event mask hasn't changed if
7 ADD fails with EEXIST.
8 - use memset to initialise most arrays now and do away with the
9 init functions.
10
11 3.45 Tue Oct 21 21:59:26 CEST 2008
12 - disable inotify usage on linux <2.6.25, as it is broken
13 (reported by Yoann Vandoorselaere).
14 - ev_stat errornously would try to add inotify watchers
15 even when inotify wasn't available (this should only
16 have a performance impact).
17 - ev_once now passes both timeout and io to the callback if both
18 occur concurrently, instead of giving timeouts precedence.
19 - disable EV_USE_INOTIFY when sys/inotify.h is too old.
20
21 3.44 Mon Sep 29 05:18:39 CEST 2008
22 - embed watchers now automatically invoke ev_loop_fork on the
23 embedded loop when the parent loop forks.
24 - new function: ev_now_update (loop).
25 - verify_watcher was not marked static.
26 - improve the "associating..." manpage section.
27 - documentation tweaks here and there.
28
29 3.43 Sun Jul 6 05:34:41 CEST 2008
30 - include more include files on windows to get struct _stati64
31 (reported by Chris Hulbert, but doesn't quite fix his issue).
32 - add missing #include <io.h> in ev.c on windows (reported by
33 Matt Tolton).
34
35 3.42 Tue Jun 17 12:12:07 CEST 2008
36 - work around yet another windows bug: FD_SET actually adds fd's
37 multiple times to the fd_*SET*, despite official MSN docs claiming
38 otherwise. Reported and well-analysed by Matt Tolton.
39 - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
40 (reported any analysed by Chris Hulbert).
41 - fix a bug in ev_ebadf (this function is only used to catch
42 programming errors in the libev user). reported by Matt Tolton.
43 - fix a bug in fd_intern on win32 (could lead to compile errors
44 under some circumstances, but would work correctly if it compiles).
45 reported by Matt Tolton.
46 - (try to) work around missing lstat on windows.
47 - pass in the write fd set as except fd set under windows. windows
48 is so uncontrollably lame that it requires this. this means that
49 switching off oobinline is not supported (but tcp/ip doesn't
50 have oob, so that would be stupid anyways.
51 - use posix module symbol to auto-detect monotonic clock presence
52 and some other default values.
53
54 3.41 Fri May 23 18:42:54 CEST 2008
55 - work around an obscure bug in winsocket select: if you
56 provide only empty fd sets then select returns WSAEINVAL. how sucky.
57 - improve timer scheduling stability and reduce use of time_epsilon.
58 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
59 codesize and makes for better cache-efficiency.
60 - use 3-based 4-heap for !EV_MINIMAL. this makes better use
61 of cpu cache lines and gives better growth behaviour than
62 2-based heaps.
63 - cache timestamp within heap for !EV_MINIMAL, to avoid random
64 memory accesses.
65 - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
66 - fix a potential aliasing issue in ev_timer_again.
67 - add/document ev_periodic_at, retract direct access to ->at.
68 - improve ev_stat docs.
69 - add portability requirements section.
70 - fix manpage headers etc.
71 - normalise WSA error codes to lower range on windows.
72 - add consistency check code that can be called automatically
73 or on demand to check for internal structures (ev_loop_verify).
74
75 3.31 Wed Apr 16 20:45:04 CEST 2008
76 - added last minute fix for ev_poll.c by Brandon Black.
77
78 3.3 Wed Apr 16 19:04:10 CEST 2008
79 - event_base_loopexit should return 0 on success
80 (W.C.A. Wijngaards).
81 - added linux eventfd support.
82 - try to autodetect epoll and inotify support
83 by libc header version if not using autoconf.
84 - new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
85 - declare functions defined in ev.h as inline if
86 C99 or gcc are available.
87 - enable inlining with gcc versions 2 and 3.
88 - work around broken poll implementations potentially
89 not clearing revents field in ev_poll (Brandon Black)
90 (no such systems are known at this time).
91 - work around a bug in realloc on openbsd and darwin,
92 also makes the errornous valgrind complaints
93 go away (noted by various people).
94 - fix ev_async_pending, add c++ wrapper for ev_async
95 (based on patch sent by Johannes Deisenhofer.
96 - add sensible set method to ev::embed.
97 - made integer constants type int in ev.h.
98
99 3.2 Wed Apr 2 17:11:19 CEST 2008
100 - fix a 64 bit overflow issue in the select backend,
101 by using fd_mask instead of int for the mask.
102 - rename internal sighandler to avoid clash with very old perls.
103 - entering ev_loop will not clear the ONESHOT or NONBLOCKING
104 flags of any outer loops anymore.
105 - add ev_async_pending.
106
107 3.1 Thu Mar 13 13:45:22 CET 2008
108 - implement ev_async watchers.
109 - only initialise signal pipe on demand.
110 - make use of sig_atomic_t configurable.
111 - improved documentation.
112
113 3.0 Mon Jan 28 13:14:47 CET 2008
114 - API/ABI bump to version 3.0.
115 - ev++.h includes "ev.h" by default now, not <ev.h>.
116 - slightly improved documentation.
117 - speed up signal detection after a fork.
118 - only optionally return trace status changed in ev_child
119 watchers.
120 - experimental (and undocumented) loop wrappers for ev++.h.
121
