2
3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 - EV::run now returns a boolean.
7 - API version 5:1.
8 - document that cleanup watchers are not available via perl.
9 - cast I32 to int in error message printf.
10 - remove dependencies on librt and libpthreads on GNU/Linux.
11
12 4.11 Sat Feb 4 19:56:26 CET 2012
13 - (libev) implement memory fences for (obsolete) llvm-gcc.
14
15 4.10 Thu Jan 19 18:54:23 CET 2012
16 - (libev) fix a race where the workaround against the epoll fork
17 bugs caused signals to not be handled anymore.
18 - (libev) correct backend_fudge for most backends, and implement
19 a windows specific workaround to avoid looping because we call
20 both select and Sleep, both with different time resolutions.
21 - e_new wasn't declared static (causing very minor .so bloat).
22 - replace more old api names by new ones.
23
24 4.03 Tue Jan 11 14:51:05 CET 2011
25 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
26 links against -lpthread anyways - as a result, EV might now take
27 advantage of fast userspace clock_gettime implementations,
28 but also links against -lrt.
29 - (libev) lots of event port bug workarounds.
30 - (libev) officially support files in I/O watchers.
31 - (libev) new function ev_feed_signal.
32 - fix documentation parts still refering to the 3.x API.
33
34 4.02 Thu Dec 30 08:27:41 CET 2010
35 - the revents argument did not stringify correctly, as only the
36 numeric value was updated, while the string value was kept from
37 previous invocations.
38
39 4.01 Sun Dec 5 12:42:13 CET 2010
40 - fully support EV_COMPAT3=0.
41 - default_fork was stupidly defined as inline.
42 - ask cpan to upgrade AnyEvent if < 5.29.
43 - support EV_EXTRA_DEFS during configuration.
44 - support -DEV_NO_LOOPS for snakker build.
45
46 4.00 Mon Oct 25 13:30:09 CEST 2010
47 - many API changes, see the manual.
48 - (libev) lots and lots of bugfixes, see the ev documentation.
49 - fix a bug where inotify usage would parse the same event
50 multiple times, causing various forms of breakage.
51 - greatly reduce stack usage for inotify (8kb to <0.5kb).
52 - expose ev_depth and ev_verify via the XS API.
53 - implement ev_cleanup watchers.
54 - (libev) ev_embed_stop did not correctly stop the watcher.
55 - (libev) disable poll backend on AIX.
56 - (libev) rename EV_TIMEOUT to EV_TIMER.
57 - (libev) add section on accept() problems to the manpage.
58 - (libev) no child watchers on win32.
59 - make code more aliasing compliant, in case perl is ever
60 translated to C.
61 - document the EV::CHECK runtime unavailability.
62 - ported to minix 3.1.7.
63
64 3.9 Thu Dec 31 07:59:59 CET 2009
65 - disable t/07* under automatic testing.
66 - increase t/09* timeouts as netbsd has *horribly* broken
67 select/kevent that *usually* sleep >>0.6s instead of 0.3.
68 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
69 EV::BACKEND_ALL.
70 - (libev) signalfd is no longer used by default.
71 - (libev) backport inotify code to C89.
72 - (libev) inotify file descriptors could leak into child processes.
73 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
74 - (libev) take advantage of inotify_init1, if available.
75 - (libev) the signal handling pipe wasn't always initialised under windows.
76 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
77 - (libev) only replace ev_stat.prev when we detect an actual difference.
78
79 3.8 Sun Aug 9 15:30:10 CEST 2009
80 - implement $loop->signal/signal_ns.
81 - (libev) incompatible change: do not necessarily reset signal
82 handler to SIG_DFL when a sighandler is stopped.
83 - (libev) ev_default_destroy did not properly free or zero some
84 members, potentially causing crashes and memory corruption on
85 repated ev_default_destroy/ev_default_loop calls.
86 - (libev) take advantage of signalfd on GNU/Linux systems.
87 - (libev) document that the signal mask might be in an unspecified
88 state when using libev's signal handling.
89 - (libev) take advantage of some GNU/Linux calls to set
90 cloexec/nonblock on fd creation, to avoid race conditions.
91 - implement internal glue code to interface more efficiently
92 with AnyEvent.
93
94 3.7 Fri Jul 17 16:49:16 CEST 2009
95 - add EV::loop_verify and EV::loop_depth.
96 - use output filehandle for i/o watchers waiting
97 for EV_WRITE, otherwise input filehandle.
98 - use common schmorp.h header.
99 - add EV::Timer->remaining.
100 - allow for subclassing of EV::Loop (see the exciting
101 EV::Loop::Async module for an example).
102 - added EV::invoke_pending and EV::pending_count.
103
104 - (libev) ev_unloop and ev_loop wrongly used a global variable to
105 exit loops, instead of using a per-loop variable.
106 - (libev) the ev_set_io_collect_interval interpretation has changed.
107 - add new functionality: EV::invoke_pending, EV::pending_count.
108 - add $timer->remaining.
109 - add EV::loop_depth.
110 - (libev) calling unloop in fork/prepare watchers will no longer poll
111 for new events.
112 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
113 for slightly higher accuracy.
114 - (libev) actually 0-initialise struct sigaction when installing
115 signals.
116
117 3.6 Tue Apr 28 02:50:37 CEST 2009
118 - keepalive(0) could decrease the refcount of the loop
119 permanently.
120 - add ev_suspend/ev_resume, also make ev_now_update
121 accessible via the XS API.
122 - most EV::<eventtype> constants were missing and have been
123 added :/.
124 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
125 - (libev) multiple timers becoming ready within an event loop
126 iteration will be invoked in the "correct" order now.
127 - (libev) do not leave the event loop early just because we have
128 no active watchers, fixing a problem when embedding a kqueue
129 loop that has active kernel events but no registered watchers
130 (reported by blacksand blacksand).
131 - (libev) correctly zero the idx values for arrays, so destroying
132 and reinitialising the default loop actually works (patch by
133 Malek Hadj-Ali).
134 - (libev) new EV::CUSTOM revents flag for use by applications.
135 - (libev) add documentation section about priorites.
136 - (libev) add a glossary to the dcoumentation.
137 - (libev) extend the ev_fork description slightly.
138 - (libev) optimize a jump out of call_pending.
139 - t/03_keepalive could fail when there was no actual error.
140
141 3.53 Sun Feb 15 02:38:20 CET 2009
142 - (libev) on win32, the event loop creation could randomly fail
143 due to an initialised variable having the wrong value.
144 - (libev) probe for CLOCK_REALTIME support at runtime as well and
145 fall back to gettimeofday if there is an error, to support older
146 operating systems with newer header files/libraries.
147 - prefer gettimeofday over clock_gettime by default.
148
149 3.52 Wed Jan 7 21:46:14 CET 2009
150 - (libev) fix some issues in the select backend when in fd_set mode.
151 - (libev) due to a thinko, instead of disabling everything but
152 select on the borked OS X platform, everything but select was
153 allowed (reported by Emanuele Giaquinta).
154 - (libev) actually verify that local and remote port are matching in
155 libev's socketpair emulation, which makes denial-of-service
156 attacks harder (but not impossible - it's windows). Make sure
157 it even works under vista, which thinks that getpeer/sockname
158 should return fantasy port numbers.
159
160 3.51 Wed Dec 24 23:01:59 CET 2008
161 - do not cache the arguments passed to callbacks if the refcount
162 indicates that the callback has stolen them.
163 - (libev) try to avoid librt on GNU/Linux.
164 - (libev) check port_getn return value dfferently, might potentially
165 avoid problems.
166 - (libev) fix a bug with stat watchers possibly causing freezes.
167 - (libev) work around OS X 10.5 breaking poll, now select is the
168 only viable choice left on that pile of garbage.
169 - play tester whore: disable some tests that typically fail only
170 on cpan tester machines.
171
172 3.49 Wed Nov 19 11:26:53 CET 2008
173 - fix typos in manpage (Alex Efros).
174 - increase timing even further, for the ever-overloaded cpan-tester
175 machines, and to the detriment of everybody else who wants a fast
176 make test.
177 - possible 5.6 compatibility.
178 - (libev) use inotify even on buggy kernels, but don't rely on it.
179 - (libev) use inotify only as an added hint on network filesystems.
180
181 3.48 Thu Oct 30 09:09:48 CET 2008
182 - (libev) use a generation counter to detect spurious epoll events
183 and recreate the kernel in such a case (sorry, it's slow, but
184 I didn't design epoll...).
185 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
186 backend in some cases.
187 - (libev) use memset to initialise most arrays now and do away
188 with the init functions.
189 - speed up event callback invocation further (~15%), by
190 not creating the object reference each time.
191 - EV::sleep was documented, but not implemented. fun.
192
193 3.45 Tue Oct 21 22:20:39 CEST 2008
194 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
195 - (libev) ev_embed will now automatically follow fork.
196 - (libev) ev_once will now pass both io and timeout events to
197 the callback when both happen concurrently, instead of giving
198 one precedence.
199 - install C library documentation as EV::libev manpage (sorry, oesi).
200 - (libev) fix a minor performance bug in ev_stat handling.
201
202 3.44 Mon Sep 29 05:16:31 CEST 2008

204
205 3.431 Sun Jul 13 00:19:02 CEST 2008

213 3.42 Mon May 26 07:36:46 CEST 2008
214 - (libev) work around another bug in windows perls and
215 windows itself: failed connects do NOT set read or write
