3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 - fully support EV_COMPAT3=0.
7
8 4.00 Mon Oct 25 13:30:09 CEST 2010
9 - many API changes, see the manual.
10 - (libev) lots and lots of bugfixes, see the ev documentation.
11 - fix a bug where inotify usage would parse the same event
12 multiple times, causing various forms of breakage.
13 - greatly reduce stack usage for inotify (8kb to <0.5kb).
14 - expose ev_depth and ev_verify via the XS API.
15 - implement ev_cleanup watchers.
16 - (libev) ev_embed_stop did not correctly stop the watcher.
17 - (libev) disable poll backend on AIX.
18 - (libev) rename EV_TIMEOUT to EV_TIMER.
19 - (libev) add section on accept() problems to the manpage.
20 - (libev) no child watchers on win32.
21 - make code more aliasing compliant, in case perl is ever
22 translated to C.
23 - document the EV::CHECK runtime unavailability.
24 - ported to minix 3.1.7.
25
26 3.9 Thu Dec 31 07:59:59 CET 2009
27 - disable t/07* under automatic testing.
28 - increase t/09* timeouts as netbsd has *horribly* broken
29 select/kevent that *usually* sleep >>0.6s instead of 0.3.
30 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
31 EV::BACKEND_ALL.
32 - (libev) signalfd is no longer used by default.
33 - (libev) backport inotify code to C89.
34 - (libev) inotify file descriptors could leak into child processes.
35 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
36 - (libev) take advantage of inotify_init1, if available.
37 - (libev) the signal handling pipe wasn't always initialised under windows.
38 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
39 - (libev) only replace ev_stat.prev when we detect an actual difference.
40
41 3.8 Sun Aug 9 15:30:10 CEST 2009
42 - implement $loop->signal/signal_ns.
43 - (libev) incompatible change: do not necessarily reset signal
44 handler to SIG_DFL when a sighandler is stopped.
45 - (libev) ev_default_destroy did not properly free or zero some
46 members, potentially causing crashes and memory corruption on
47 repated ev_default_destroy/ev_default_loop calls.
48 - (libev) take advantage of signalfd on GNU/Linux systems.
49 - (libev) document that the signal mask might be in an unspecified
50 state when using libev's signal handling.
51 - (libev) take advantage of some GNU/Linux calls to set
52 cloexec/nonblock on fd creation, to avoid race conditions.
53 - implement internal glue code to interface more efficiently
54 with AnyEvent.
55
56 3.7 Fri Jul 17 16:49:16 CEST 2009
57 - add EV::loop_verify and EV::loop_depth.
58 - use output filehandle for i/o watchers waiting
59 for EV_WRITE, otherwise input filehandle.
60 - use common schmorp.h header.
61 - add EV::Timer->remaining.
62 - allow for subclassing of EV::Loop (see the exciting
63 EV::Loop::Async module for an example).
64 - added EV::invoke_pending and EV::pending_count.
65
66 - (libev) ev_unloop and ev_loop wrongly used a global variable to
67 exit loops, instead of using a per-loop variable.
68 - (libev) the ev_set_io_collect_interval interpretation has changed.
69 - add new functionality: EV::invoke_pending, EV::pending_count.
70 - add $timer->remaining.
71 - add EV::loop_depth.
72 - (libev) calling unloop in fork/prepare watchers will no longer poll
73 for new events.
74 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
75 for slightly higher accuracy.
76 - (libev) actually 0-initialise struct sigaction when installing
77 signals.
78
79 3.6 Tue Apr 28 02:50:37 CEST 2009
80 - keepalive(0) could decrease the refcount of the loop
81 permanently.
82 - add ev_suspend/ev_resume, also make ev_now_update
83 accessible via the XS API.
84 - most EV::<eventtype> constants were missing and have been
85 added :/.
86 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
87 - (libev) multiple timers becoming ready within an event loop
88 iteration will be invoked in the "correct" order now.
89 - (libev) do not leave the event loop early just because we have
90 no active watchers, fixing a problem when embedding a kqueue
91 loop that has active kernel events but no registered watchers
92 (reported by blacksand blacksand).
93 - (libev) correctly zero the idx values for arrays, so destroying
94 and reinitialising the default loop actually works (patch by
95 Malek Hadj-Ali).
96 - (libev) new EV::CUSTOM revents flag for use by applications.
97 - (libev) add documentation section about priorites.
98 - (libev) add a glossary to the dcoumentation.
99 - (libev) extend the ev_fork description slightly.
100 - (libev) optimize a jump out of call_pending.
101 - t/03_keepalive could fail when there was no actual error.
102
103 3.53 Sun Feb 15 02:38:20 CET 2009
104 - (libev) on win32, the event loop creation could randomly fail
105 due to an initialised variable having the wrong value.
106 - (libev) probe for CLOCK_REALTIME support at runtime as well and
107 fall back to gettimeofday if there is an error, to support older
108 operating systems with newer header files/libraries.
109 - prefer gettimeofday over clock_gettime by default.
110
111 3.52 Wed Jan 7 21:46:14 CET 2009
112 - (libev) fix some issues in the select backend when in fd_set mode.
113 - (libev) due to a thinko, instead of disabling everything but
114 select on the borked OS X platform, everything but select was
115 allowed (reported by Emanuele Giaquinta).
116 - (libev) actually verify that local and remote port are matching in
117 libev's socketpair emulation, which makes denial-of-service
118 attacks harder (but not impossible - it's windows). Make sure
119 it even works under vista, which thinks that getpeer/sockname
120 should return fantasy port numbers.
121
122 3.51 Wed Dec 24 23:01:59 CET 2008
123 - do not cache the arguments passed to callbacks if the refcount
124 indicates that the callback has stolen them.
125 - (libev) try to avoid librt on GNU/Linux.
126 - (libev) check port_getn return value dfferently, might potentially
127 avoid problems.
128 - (libev) fix a bug with stat watchers possibly causing freezes.
129 - (libev) work around OS X 10.5 breaking poll, now select is the
130 only viable choice left on that pile of garbage.
131 - play tester whore: disable some tests that typically fail only
132 on cpan tester machines.
133
134 3.49 Wed Nov 19 11:26:53 CET 2008
135 - fix typos in manpage (Alex Efros).
136 - increase timing even further, for the ever-overloaded cpan-tester
137 machines, and to the detriment of everybody else who wants a fast
138 make test.
139 - possible 5.6 compatibility.
140 - (libev) use inotify even on buggy kernels, but don't rely on it.
141 - (libev) use inotify only as an added hint on network filesystems.
142
143 3.48 Thu Oct 30 09:09:48 CET 2008
144 - (libev) use a generation counter to detect spurious epoll events
145 and recreate the kernel in such a case (sorry, it's slow, but
146 I didn't design epoll...).
147 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
148 backend in some cases.
149 - (libev) use memset to initialise most arrays now and do away
150 with the init functions.
151 - speed up event callback invocation further (~15%), by
152 not creating the object reference each time.
153 - EV::sleep was documented, but not implemented. fun.
154
155 3.45 Tue Oct 21 22:20:39 CEST 2008
156 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
157 - (libev) ev_embed will now automatically follow fork.
158 - (libev) ev_once will now pass both io and timeout events to
159 the callback when both happen concurrently, instead of giving
160 one precedence.
161 - install C library documentation as EV::libev manpage (sorry, oesi).
162 - (libev) fix a minor performance bug in ev_stat handling.
163
164 3.44 Mon Sep 29 05:16:31 CEST 2008
165 - (libev) add EV::now_update and $loop->now_update.
166
167 3.431 Sun Jul 13 00:19:02 CEST 2008
168 - made the EV::embed callback optional again. reported by
169 Vladimir Timofeev.
170
171 3.43 Tue Jul 8 20:56:31 CEST 2008
172 - disabled warnings in EV.pm, the CHECK issue is now understood
173 and harmless.
174
175 3.42 Mon May 26 07:36:46 CEST 2008
176 - (libev) work around another bug in windows perls and
177 windows itself: failed connects do NOT set read or write

179
180 3.41 Thu May 22 01:39:40 CEST 2008

183 - expose ev_loop_verify to perl code.
184 - clarify documentation for periodic reschedule callbacks.
185 - verify that the passed callback argument is indeed a code

187 speed increase (as well as saving memory).
188
189 3.4 Tue May 20 21:51:55 CEST 2008
190 - (libev) work around both a windows bug and a bug in perl's
191 select on windows when not waiting for any file descriptors.
192 - bundle ev.pod into the tarball, just to increase its size
193 (and for the poor internetless person).
194
195 3.33 Sun May 18 12:43:04 CEST 2008
