3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 4.00
7 - fix a bug where inotify usage would parse the same event
8 multiple times, causing various forms of breakage.
9 - greatly reduce stack usage for inotify (8kb to <0.5kb).
10 - expose ev_loop_depth via the XS API.
11 - (libev) ev_embed_stop did not correctly stop the watcher.
12 - (libev) disable poll backend on AIX.
13 - (libev) rename EV_TIMEOUT to EV_TIMER.
14 - (libev) add section on accept() problems to the manpage.
15
16 3.9 Thu Dec 31 07:59:59 CET 2009
17 - disable t/07* under automatic testing.
18 - increase t/09* timeouts as netbsd has *horribly* broken
19 select/kevent that *usually* sleep >>0.6s instead of 0.3.
20 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
21 EV::BACKEND_ALL.
22 - (libev) signalfd is no longer used by default.
23 - (libev) backport inotify code to C89.
24 - (libev) inotify file descriptors could leak into child processes.
25 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
26 - (libev) take advantage of inotify_init1, if available.
27 - (libev) the signal handling pipe wasn't always initialised under windows.
28 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
29 - (libev) only replace ev_stat.prev when we detect an actual difference.
30
31 3.8 Sun Aug 9 15:30:10 CEST 2009
32 - implement $loop->signal/signal_ns.
33 - (libev) incompatible change: do not necessarily reset signal
34 handler to SIG_DFL when a sighandler is stopped.
35 - (libev) ev_default_destroy did not properly free or zero some
36 members, potentially causing crashes and memory corruption on
37 repated ev_default_destroy/ev_default_loop calls.
38 - (libev) take advantage of signalfd on GNU/Linux systems.
39 - (libev) document that the signal mask might be in an unspecified
40 state when using libev's signal handling.
41 - (libev) take advantage of some GNU/Linux calls to set
42 cloexec/nonblock on fd creation, to avoid race conditions.
43 - implement internal glue code to interface more efficiently
44 with AnyEvent.
45
46 3.7 Fri Jul 17 16:49:16 CEST 2009
47 - add EV::loop_verify and EV::loop_depth.
48 - use output filehandle for i/o watchers waiting
49 for EV_WRITE, otherwise input filehandle.
50 - use common schmorp.h header.
51 - add EV::Timer->remaining.
52 - allow for subclassing of EV::Loop (see the exciting
53 EV::Loop::Async module for an example).
54 - added EV::invoke_pending and EV::pending_count.
55
56 - (libev) ev_unloop and ev_loop wrongly used a global variable to
57 exit loops, instead of using a per-loop variable.
58 - (libev) the ev_set_io_collect_interval interpretation has changed.
59 - add new functionality: EV::invoke_pending, EV::pending_count.
60 - add $timer->remaining.
61 - add EV::loop_depth.
62 - (libev) calling unloop in fork/prepare watchers will no longer poll
63 for new events.
64 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
65 for slightly higher accuracy.
66 - (libev) actually 0-initialise struct sigaction when installing
67 signals.
68
69 3.6 Tue Apr 28 02:50:37 CEST 2009
70 - keepalive(0) could decrease the refcount of the loop
71 permanently.
72 - add ev_suspend/ev_resume, also make ev_now_update
73 accessible via the XS API.
74 - most EV::<eventtype> constants were missing and have been
75 added :/.
76 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
77 - (libev) multiple timers becoming ready within an event loop
78 iteration will be invoked in the "correct" order now.
79 - (libev) do not leave the event loop early just because we have
80 no active watchers, fixing a problem when embedding a kqueue
81 loop that has active kernel events but no registered watchers
82 (reported by blacksand blacksand).
83 - (libev) correctly zero the idx values for arrays, so destroying
84 and reinitialising the default loop actually works (patch by
85 Malek Hadj-Ali).
86 - (libev) new EV::CUSTOM revents flag for use by applications.
87 - (libev) add documentation section about priorites.
88 - (libev) add a glossary to the dcoumentation.
89 - (libev) extend the ev_fork description slightly.
90 - (libev) optimize a jump out of call_pending.
91 - t/03_keepalive could fail when there was no actual error.
92
93 3.53 Sun Feb 15 02:38:20 CET 2009
94 - (libev) on win32, the event loop creation could randomly fail
95 due to an initialised variable having the wrong value.
96 - (libev) probe for CLOCK_REALTIME support at runtime as well and
97 fall back to gettimeofday if there is an error, to support older
98 operating systems with newer header files/libraries.
99 - prefer gettimeofday over clock_gettime by default.
100
101 3.52 Wed Jan 7 21:46:14 CET 2009
102 - (libev) fix some issues in the select backend when in fd_set mode.
103 - (libev) due to a thinko, instead of disabling everything but
104 select on the borked OS X platform, everything but select was
105 allowed (reported by Emanuele Giaquinta).
106 - (libev) actually verify that local and remote port are matching in
107 libev's socketpair emulation, which makes denial-of-service
108 attacks harder (but not impossible - it's windows). Make sure
109 it even works under vista, which thinks that getpeer/sockname
110 should return fantasy port numbers.
111
112 3.51 Wed Dec 24 23:01:59 CET 2008
113 - do not cache the arguments passed to callbacks if the refcount
114 indicates that the callback has stolen them.
115 - (libev) try to avoid librt on GNU/Linux.
116 - (libev) check port_getn return value dfferently, might potentially
117 avoid problems.
118 - (libev) fix a bug with stat watchers possibly causing freezes.
119 - (libev) work around OS X 10.5 breaking poll, now select is the
120 only viable choice left on that pile of garbage.
121 - play tester whore: disable some tests that typically fail only
122 on cpan tester machines.
123
124 3.49 Wed Nov 19 11:26:53 CET 2008
125 - fix typos in manpage (Alex Efros).
126 - increase timing even further, for the ever-overloaded cpan-tester
127 machines, and to the detriment of everybody else who wants a fast
128 make test.
129 - possible 5.6 compatibility.
130 - (libev) use inotify even on buggy kernels, but don't rely on it.
131 - (libev) use inotify only as an added hint on network filesystems.
132
133 3.48 Thu Oct 30 09:09:48 CET 2008
134 - (libev) use a generation counter to detect spurious epoll events
135 and recreate the kernel in such a case (sorry, it's slow, but
136 I didn't design epoll...).
137 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
138 backend in some cases.
139 - (libev) use memset to initialise most arrays now and do away
140 with the init functions.
141 - speed up event callback invocation further (~15%), by
142 not creating the object reference each time.
143 - EV::sleep was documented, but not implemented. fun.
144
145 3.45 Tue Oct 21 22:20:39 CEST 2008
146 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
147 - (libev) ev_embed will now automatically follow fork.
148 - (libev) ev_once will now pass both io and timeout events to
149 the callback when both happen concurrently, instead of giving
150 one precedence.
151 - install C library documentation as EV::libev manpage (sorry, oesi).
152 - (libev) fix a minor performance bug in ev_stat handling.
153
154 3.44 Mon Sep 29 05:16:31 CEST 2008
155 - (libev) add EV::now_update and $loop->now_update.
156
157 3.431 Sun Jul 13 00:19:02 CEST 2008
158 - made the EV::embed callback optional again. reported by
159 Vladimir Timofeev.
160
161 3.43 Tue Jul 8 20:56:31 CEST 2008
162 - disabled warnings in EV.pm, the CHECK issue is now understood
163 and harmless.
164
165 3.42 Mon May 26 07:36:46 CEST 2008
166 - (libev) work around another bug in windows perls and
167 windows itself: failed connects do NOT set read or write
168 flags in select, but this version of libev will.
169
170 3.41 Thu May 22 01:39:40 CEST 2008

173 - expose ev_loop_verify to perl code.
174 - clarify documentation for periodic reschedule callbacks.
175 - verify that the passed callback argument is indeed a code
176 reference, for earlier error reporting and a nice calling
177 speed increase (as well as saving memory).
178
179 3.4 Tue May 20 21:51:55 CEST 2008
180 - (libev) work around both a windows bug and a bug in perl's
181 select on windows when not waiting for any file descriptors.
182 - bundle ev.pod into the tarball, just to increase its size
183 (and for the poor internetless person).
184
185 3.33 Sun May 18 12:43:04 CEST 2008
186 - (libev) use numerous enhancements such as a more
187 cache-friendly 4-heap and heap index caching for timers.
