3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 4.11 Sat Feb 4 19:56:26 CET 2012
7 - (libev) implement memory fences for (obsolete) llvm-gcc.
8
9 4.10 Thu Jan 19 18:54:23 CET 2012
10 - (libev) fix a race where the workaround against the epoll fork
11 bugs caused signals to not be handled anymore.
12 - (libev) correct backend_fudge for most backends, and implement
13 a windows specific workaround to avoid looping because we call
14 both select and Sleep, both with different time resolutions.
15 - e_new wasn't declared static (causing very minor .so bloat).
16 - replace more old api names by new ones.
17
18 4.03 Tue Jan 11 14:51:05 CET 2011
19 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
20 links against -lpthread anyways - as a result, EV might now take
21 advantage of fast userspace clock_gettime implementations,
22 but also links against -lrt.
23 - (libev) lots of event port bug workarounds.
24 - (libev) officially support files in I/O watchers.
25 - (libev) new function ev_feed_signal.
26 - fix documentation parts still refering to the 3.x API.
27
28 4.02 Thu Dec 30 08:27:41 CET 2010
29 - the revents argument did not stringify correctly, as only the
30 numeric value was updated, while the string value was kept from
31 previous invocations.
32
33 4.01 Sun Dec 5 12:42:13 CET 2010
34 - fully support EV_COMPAT3=0.
35 - default_fork was stupidly defined as inline.
36 - ask cpan to upgrade AnyEvent if < 5.29.
37 - support EV_EXTRA_DEFS during configuration.
38 - support -DEV_NO_LOOPS for snakker build.
39
40 4.00 Mon Oct 25 13:30:09 CEST 2010
41 - many API changes, see the manual.
42 - (libev) lots and lots of bugfixes, see the ev documentation.
43 - fix a bug where inotify usage would parse the same event
44 multiple times, causing various forms of breakage.
45 - greatly reduce stack usage for inotify (8kb to <0.5kb).
46 - expose ev_depth and ev_verify via the XS API.
47 - implement ev_cleanup watchers.
48 - (libev) ev_embed_stop did not correctly stop the watcher.
49 - (libev) disable poll backend on AIX.
50 - (libev) rename EV_TIMEOUT to EV_TIMER.
51 - (libev) add section on accept() problems to the manpage.
52 - (libev) no child watchers on win32.
53 - make code more aliasing compliant, in case perl is ever
54 translated to C.
55 - document the EV::CHECK runtime unavailability.
56 - ported to minix 3.1.7.
57
58 3.9 Thu Dec 31 07:59:59 CET 2009
59 - disable t/07* under automatic testing.
60 - increase t/09* timeouts as netbsd has *horribly* broken
61 select/kevent that *usually* sleep >>0.6s instead of 0.3.
62 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
63 EV::BACKEND_ALL.
64 - (libev) signalfd is no longer used by default.
65 - (libev) backport inotify code to C89.
66 - (libev) inotify file descriptors could leak into child processes.
67 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
68 - (libev) take advantage of inotify_init1, if available.
69 - (libev) the signal handling pipe wasn't always initialised under windows.
70 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
71 - (libev) only replace ev_stat.prev when we detect an actual difference.
72
73 3.8 Sun Aug 9 15:30:10 CEST 2009
74 - implement $loop->signal/signal_ns.
75 - (libev) incompatible change: do not necessarily reset signal
76 handler to SIG_DFL when a sighandler is stopped.
77 - (libev) ev_default_destroy did not properly free or zero some
78 members, potentially causing crashes and memory corruption on
79 repated ev_default_destroy/ev_default_loop calls.
80 - (libev) take advantage of signalfd on GNU/Linux systems.
81 - (libev) document that the signal mask might be in an unspecified
82 state when using libev's signal handling.
83 - (libev) take advantage of some GNU/Linux calls to set
84 cloexec/nonblock on fd creation, to avoid race conditions.
85 - implement internal glue code to interface more efficiently
86 with AnyEvent.
87
88 3.7 Fri Jul 17 16:49:16 CEST 2009
89 - add EV::loop_verify and EV::loop_depth.
90 - use output filehandle for i/o watchers waiting
91 for EV_WRITE, otherwise input filehandle.
92 - use common schmorp.h header.
93 - add EV::Timer->remaining.
94 - allow for subclassing of EV::Loop (see the exciting
95 EV::Loop::Async module for an example).
96 - added EV::invoke_pending and EV::pending_count.
97
98 - (libev) ev_unloop and ev_loop wrongly used a global variable to
99 exit loops, instead of using a per-loop variable.
100 - (libev) the ev_set_io_collect_interval interpretation has changed.
101 - add new functionality: EV::invoke_pending, EV::pending_count.
102 - add $timer->remaining.
103 - add EV::loop_depth.
104 - (libev) calling unloop in fork/prepare watchers will no longer poll
105 for new events.
106 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
107 for slightly higher accuracy.
108 - (libev) actually 0-initialise struct sigaction when installing
109 signals.
110
111 3.6 Tue Apr 28 02:50:37 CEST 2009
112 - keepalive(0) could decrease the refcount of the loop
113 permanently.
114 - add ev_suspend/ev_resume, also make ev_now_update
115 accessible via the XS API.
116 - most EV::<eventtype> constants were missing and have been
117 added :/.
118 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
119 - (libev) multiple timers becoming ready within an event loop
120 iteration will be invoked in the "correct" order now.
121 - (libev) do not leave the event loop early just because we have
122 no active watchers, fixing a problem when embedding a kqueue
123 loop that has active kernel events but no registered watchers
124 (reported by blacksand blacksand).
125 - (libev) correctly zero the idx values for arrays, so destroying
126 and reinitialising the default loop actually works (patch by
127 Malek Hadj-Ali).
128 - (libev) new EV::CUSTOM revents flag for use by applications.
129 - (libev) add documentation section about priorites.
130 - (libev) add a glossary to the dcoumentation.
131 - (libev) extend the ev_fork description slightly.
132 - (libev) optimize a jump out of call_pending.
133 - t/03_keepalive could fail when there was no actual error.
134
135 3.53 Sun Feb 15 02:38:20 CET 2009
136 - (libev) on win32, the event loop creation could randomly fail
137 due to an initialised variable having the wrong value.
138 - (libev) probe for CLOCK_REALTIME support at runtime as well and
139 fall back to gettimeofday if there is an error, to support older
140 operating systems with newer header files/libraries.
141 - prefer gettimeofday over clock_gettime by default.
142
143 3.52 Wed Jan 7 21:46:14 CET 2009
144 - (libev) fix some issues in the select backend when in fd_set mode.
145 - (libev) due to a thinko, instead of disabling everything but
146 select on the borked OS X platform, everything but select was
147 allowed (reported by Emanuele Giaquinta).
148 - (libev) actually verify that local and remote port are matching in
149 libev's socketpair emulation, which makes denial-of-service
150 attacks harder (but not impossible - it's windows). Make sure
151 it even works under vista, which thinks that getpeer/sockname
152 should return fantasy port numbers.
153
154 3.51 Wed Dec 24 23:01:59 CET 2008
155 - do not cache the arguments passed to callbacks if the refcount
156 indicates that the callback has stolen them.
157 - (libev) try to avoid librt on GNU/Linux.
158 - (libev) check port_getn return value dfferently, might potentially
159 avoid problems.
160 - (libev) fix a bug with stat watchers possibly causing freezes.
161 - (libev) work around OS X 10.5 breaking poll, now select is the
162 only viable choice left on that pile of garbage.
163 - play tester whore: disable some tests that typically fail only
164 on cpan tester machines.
165
166 3.49 Wed Nov 19 11:26:53 CET 2008
167 - fix typos in manpage (Alex Efros).
168 - increase timing even further, for the ever-overloaded cpan-tester
169 machines, and to the detriment of everybody else who wants a fast
170 make test.
171 - possible 5.6 compatibility.
172 - (libev) use inotify even on buggy kernels, but don't rely on it.
173 - (libev) use inotify only as an added hint on network filesystems.
174
175 3.48 Thu Oct 30 09:09:48 CET 2008
176 - (libev) use a generation counter to detect spurious epoll events
177 and recreate the kernel in such a case (sorry, it's slow, but
178 I didn't design epoll...).
179 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
180 backend in some cases.
181 - (libev) use memset to initialise most arrays now and do away
182 with the init functions.
183 - speed up event callback invocation further (~15%), by
184 not creating the object reference each time.
185 - EV::sleep was documented, but not implemented. fun.
186
187 3.45 Tue Oct 21 22:20:39 CEST 2008
188 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
189 - (libev) ev_embed will now automatically follow fork.
190 - (libev) ev_once will now pass both io and timeout events to
191 the callback when both happen concurrently, instead of giving
192 one precedence.
193 - install C library documentation as EV::libev manpage (sorry, oesi).
194 - (libev) fix a minor performance bug in ev_stat handling.
195
196 3.44 Mon Sep 29 05:16:31 CEST 2008
197 - (libev) add EV::now_update and $loop->now_update.
198
199 3.431 Sun Jul 13 00:19:02 CEST 2008

206
207 3.42 Mon May 26 07:36:46 CEST 2008
208 - (libev) work around another bug in windows perls and
209 windows itself: failed connects do NOT set read or write

219 speed increase (as well as saving memory).
220
221 3.4 Tue May 20 21:51:55 CEST 2008
222 - (libev) work around both a windows bug and a bug in perl's
223 select on windows when not waiting for any file descriptors.
224 - bundle ev.pod into the tarball, just to increase its size
225 (and for the poor internetless person).
