3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 4.20 Sat Jun 20 13:07:34 CEST 2015
7 - added stability canary support.
8 - truly rely on automatic configuration for clock_gettime and others.
9 unfortunately, this doesn't help with activeperl and similar perls,
10 which define _POSIX_TIMERS without actually implementing any of it.
11 - (libev, ecb) make it compile as C++ again.
12 - (libev) fix a potential aliasing issue when accessing watcher cbs.
13
14 4.18 Sat Sep 6 20:37:23 CEST 2014
15 - use slightly better weay to find includes, to support multiarch
16 on newer perls.
17
18 4.17 Fri Apr 11 06:22:38 CEST 2014
19 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
20 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
21 in 5.18. What's so attractive about giving a shit about backwards
22 compatibility - I will never understand.
23
24 4.16 Sat Mar 8 16:49:05 CET 2014
25 - make sure EV::CHECK is available at all times.
26 - avoid a spurious warning when perl -w overrides "no warnings".
27 - use perl's signal implementation on WIN32.
28 - ensure extern "C" function pointers are used for externally-visible
29 pointers.
30 - (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
31 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
32 - (libev) in the absence of autoconf, do not use the clock syscall
33 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
34 doing clock_gettime in userspace).
35 - (ecb) work around memory barriers and volatile apparently both being
36 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
37
38 4.15 Fri Mar 1 12:15:53 CET 2013
39 - (libev) upgrade to 4.15 - too many changes to list.
40 - EV::run now returns a boolean.
41 - API version 5:1.
42 - document that cleanup watchers are not available via perl.
43 - cast I32 to int in error message printf.
44 - remove dependencies on librt and libpthreads on GNU/Linux.
45
46 4.11 Sat Feb 4 19:56:26 CET 2012
47 - (libev) implement memory fences for (obsolete) llvm-gcc.
48
49 4.10 Thu Jan 19 18:54:23 CET 2012
50 - (libev) fix a race where the workaround against the epoll fork
51 bugs caused signals to not be handled anymore.
52 - (libev) correct backend_fudge for most backends, and implement
53 a windows specific workaround to avoid looping because we call
54 both select and Sleep, both with different time resolutions.
55 - e_new wasn't declared static (causing very minor .so bloat).
56 - replace more old api names by new ones.
57
58 4.03 Tue Jan 11 14:51:05 CET 2011
59 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
60 links against -lpthread anyways - as a result, EV might now take
61 advantage of fast userspace clock_gettime implementations,
62 but also links against -lrt.
63 - (libev) lots of event port bug workarounds.
64 - (libev) officially support files in I/O watchers.
65 - (libev) new function ev_feed_signal.
66 - fix documentation parts still refering to the 3.x API.
67
68 4.02 Thu Dec 30 08:27:41 CET 2010
69 - the revents argument did not stringify correctly, as only the
70 numeric value was updated, while the string value was kept from
71 previous invocations.
72
73 4.01 Sun Dec 5 12:42:13 CET 2010
74 - fully support EV_COMPAT3=0.
75 - default_fork was stupidly defined as inline.
76 - ask cpan to upgrade AnyEvent if < 5.29.
77 - support EV_EXTRA_DEFS during configuration.
78 - support -DEV_NO_LOOPS for snakker build.
79
80 4.00 Mon Oct 25 13:30:09 CEST 2010
81 - many API changes, see the manual.
82 - (libev) lots and lots of bugfixes, see the ev documentation.
83 - fix a bug where inotify usage would parse the same event
84 multiple times, causing various forms of breakage.
85 - greatly reduce stack usage for inotify (8kb to <0.5kb).
86 - expose ev_depth and ev_verify via the XS API.
87 - implement ev_cleanup watchers.
88 - (libev) ev_embed_stop did not correctly stop the watcher.
89 - (libev) disable poll backend on AIX.
90 - (libev) rename EV_TIMEOUT to EV_TIMER.
91 - (libev) add section on accept() problems to the manpage.
92 - (libev) no child watchers on win32.
93 - make code more aliasing compliant, in case perl is ever
94 translated to C.
95 - document the EV::CHECK runtime unavailability.
96 - ported to minix 3.1.7.
97
98 3.9 Thu Dec 31 07:59:59 CET 2009
99 - disable t/07* under automatic testing.
100 - increase t/09* timeouts as netbsd has *horribly* broken
101 select/kevent that *usually* sleep >>0.6s instead of 0.3.
102 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
103 EV::BACKEND_ALL.
104 - (libev) signalfd is no longer used by default.
105 - (libev) backport inotify code to C89.
106 - (libev) inotify file descriptors could leak into child processes.
107 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
108 - (libev) take advantage of inotify_init1, if available.
109 - (libev) the signal handling pipe wasn't always initialised under windows.
110 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
111 - (libev) only replace ev_stat.prev when we detect an actual difference.
112
113 3.8 Sun Aug 9 15:30:10 CEST 2009
114 - implement $loop->signal/signal_ns.
115 - (libev) incompatible change: do not necessarily reset signal
116 handler to SIG_DFL when a sighandler is stopped.
117 - (libev) ev_default_destroy did not properly free or zero some
118 members, potentially causing crashes and memory corruption on
119 repated ev_default_destroy/ev_default_loop calls.
120 - (libev) take advantage of signalfd on GNU/Linux systems.
121 - (libev) document that the signal mask might be in an unspecified
122 state when using libev's signal handling.
123 - (libev) take advantage of some GNU/Linux calls to set
124 cloexec/nonblock on fd creation, to avoid race conditions.
125 - implement internal glue code to interface more efficiently
126 with AnyEvent.
127
128 3.7 Fri Jul 17 16:49:16 CEST 2009
129 - add EV::loop_verify and EV::loop_depth.
130 - use output filehandle for i/o watchers waiting
131 for EV_WRITE, otherwise input filehandle.
132 - use common schmorp.h header.
133 - add EV::Timer->remaining.
134 - allow for subclassing of EV::Loop (see the exciting
135 EV::Loop::Async module for an example).
136 - added EV::invoke_pending and EV::pending_count.
137
138 - (libev) ev_unloop and ev_loop wrongly used a global variable to
139 exit loops, instead of using a per-loop variable.
140 - (libev) the ev_set_io_collect_interval interpretation has changed.
141 - add new functionality: EV::invoke_pending, EV::pending_count.
142 - add $timer->remaining.
143 - add EV::loop_depth.
144 - (libev) calling unloop in fork/prepare watchers will no longer poll
145 for new events.
146 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
147 for slightly higher accuracy.
148 - (libev) actually 0-initialise struct sigaction when installing
149 signals.
150
151 3.6 Tue Apr 28 02:50:37 CEST 2009
152 - keepalive(0) could decrease the refcount of the loop
153 permanently.
154 - add ev_suspend/ev_resume, also make ev_now_update
155 accessible via the XS API.
156 - most EV::<eventtype> constants were missing and have been
157 added :/.
158 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
159 - (libev) multiple timers becoming ready within an event loop
160 iteration will be invoked in the "correct" order now.
161 - (libev) do not leave the event loop early just because we have
162 no active watchers, fixing a problem when embedding a kqueue
163 loop that has active kernel events but no registered watchers
164 (reported by blacksand blacksand).
165 - (libev) correctly zero the idx values for arrays, so destroying
166 and reinitialising the default loop actually works (patch by
167 Malek Hadj-Ali).
168 - (libev) new EV::CUSTOM revents flag for use by applications.
169 - (libev) add documentation section about priorites.
170 - (libev) add a glossary to the dcoumentation.
171 - (libev) extend the ev_fork description slightly.
172 - (libev) optimize a jump out of call_pending.
173 - t/03_keepalive could fail when there was no actual error.
174
175 3.53 Sun Feb 15 02:38:20 CET 2009
176 - (libev) on win32, the event loop creation could randomly fail
177 due to an initialised variable having the wrong value.
178 - (libev) probe for CLOCK_REALTIME support at runtime as well and
179 fall back to gettimeofday if there is an error, to support older
180 operating systems with newer header files/libraries.
181 - prefer gettimeofday over clock_gettime by default.
182
183 3.52 Wed Jan 7 21:46:14 CET 2009
184 - (libev) fix some issues in the select backend when in fd_set mode.
185 - (libev) due to a thinko, instead of disabling everything but
186 select on the borked OS X platform, everything but select was
187 allowed (reported by Emanuele Giaquinta).
188 - (libev) actually verify that local and remote port are matching in
189 libev's socketpair emulation, which makes denial-of-service
190 attacks harder (but not impossible - it's windows). Make sure
191 it even works under vista, which thinks that getpeer/sockname
192 should return fantasy port numbers.
193
194 3.51 Wed Dec 24 23:01:59 CET 2008
195 - do not cache the arguments passed to callbacks if the refcount
196 indicates that the callback has stolen them.
197 - (libev) try to avoid librt on GNU/Linux.
198 - (libev) check port_getn return value dfferently, might potentially
199 avoid problems.
200 - (libev) fix a bug with stat watchers possibly causing freezes.
201 - (libev) work around OS X 10.5 breaking poll, now select is the
202 only viable choice left on that pile of garbage.
203 - play tester whore: disable some tests that typically fail only
204 on cpan tester machines.
205
206 3.49 Wed Nov 19 11:26:53 CET 2008
207 - fix typos in manpage (Alex Efros).
208 - increase timing even further, for the ever-overloaded cpan-tester
209 machines, and to the detriment of everybody else who wants a fast
210 make test.
211 - possible 5.6 compatibility.
212 - (libev) use inotify even on buggy kernels, but don't rely on it.
213 - (libev) use inotify only as an added hint on network filesystems.
214
215 3.48 Thu Oct 30 09:09:48 CET 2008
216 - (libev) use a generation counter to detect spurious epoll events
217 and recreate the kernel in such a case (sorry, it's slow, but
218 I didn't design epoll...).
219 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
220 backend in some cases.
221 - (libev) use memset to initialise most arrays now and do away
222 with the init functions.
223 - speed up event callback invocation further (~15%), by
224 not creating the object reference each time.
225 - EV::sleep was documented, but not implemented. fun.
226
227 3.45 Tue Oct 21 22:20:39 CEST 2008
228 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
229 - (libev) ev_embed will now automatically follow fork.
230 - (libev) ev_once will now pass both io and timeout events to
231 the callback when both happen concurrently, instead of giving
232 one precedence.
233 - install C library documentation as EV::libev manpage (sorry, oesi).
234 - (libev) fix a minor performance bug in ev_stat handling.
235
236 3.44 Mon Sep 29 05:16:31 CEST 2008
237 - (libev) add EV::now_update and $loop->now_update.
238
239 3.431 Sun Jul 13 00:19:02 CEST 2008
240 - made the EV::embed callback optional again. reported by
241 Vladimir Timofeev.
242
243 3.43 Tue Jul 8 20:56:31 CEST 2008
244 - disabled warnings in EV.pm, the CHECK issue is now understood
245 and harmless.
246
247 3.42 Mon May 26 07:36:46 CEST 2008
248 - (libev) work around another bug in windows perls and
249 windows itself: failed connects do NOT set read or write

251
252 3.41 Thu May 22 01:39:40 CEST 2008

255 - expose ev_loop_verify to perl code.
256 - clarify documentation for periodic reschedule callbacks.
257 - verify that the passed callback argument is indeed a code
258 reference, for earlier error reporting and a nice calling
259 speed increase (as well as saving memory).
260
261 3.4 Tue May 20 21:51:55 CEST 2008
262 - (libev) work around both a windows bug and a bug in perl's
263 select on windows when not waiting for any file descriptors.
264 - bundle ev.pod into the tarball, just to increase its size
265 (and for the poor internetless person).
266
267 3.33 Sun May 18 12:43:04 CEST 2008
268 - (libev) use numerous enhancements such as a more
269 cache-friendly 4-heap and heap index caching for timers.
