3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 4.26 Mon Jun 24 23:39:40 CEST 2019
7 - (libev) included experimental linux aio backend.
8 - allow the linux aio backend to be used by default
9 only when explicitly configured during Makefile.PL time.
10
11 4.25 Fri Dec 21 08:04:26 CET 2018
12 - (libev) updated to libev 4.25, minor fixes and enhancements.
13 - document the requirement to "use EV" when using EV::MakeMaker.
14 - only use __register_atfork with glibc and uclibc, as musl
15 defines __linux__, but doesn't implement the linux standard
16 base ABI, nor makes itself detectable via a macro, both apparently
17 by design, winning the "broken by design 2016 award" - well done.
18 - correct EV::periodic example 24h after midnight -> one day after
19 midnight (reported by Felix Ostmann).
20
21 4.22 Sun Dec 20 02:34:39 CET 2015
22 - (libev) when epoll detects unremovable fds in the fd set, rebuild
23 only the epoll descriptor, not the signal pipe, to avoid
24 SIGPIPE in ev_async_send. This doesn't solve it on fork,
25 so document what needs to be done in ev_loop_fork
26 (analyzed by Benjamin Mahler).
27 - (libev) remove superfluous sys/timeb.h include on win32
28 (analyzed by Jason Madden).
29 - updated libecb.
30
31 4.21 Mon Jul 13 21:47:33 CEST 2015
32 - allow argument in timer->again.
33 - document timer->remaining.
34 - document default repeat value for timer->set.
35
36 4.20 Sat Jun 20 13:07:34 CEST 2015
37 - added stability canary support.
38 - truly rely on automatic configuration for clock_gettime and others.
39 unfortunately, this doesn't help with activeperl and similar perls,
40 which define _POSIX_TIMERS without actually implementing any of it.
41 - (libev, ecb) make it compile as C++ again.
42 - (libev) fix a potential aliasing issue when accessing watcher cbs.
43
44 4.18 Sat Sep 6 20:37:23 CEST 2014
45 - use slightly better weay to find includes, to support multiarch
46 on newer perls.
47
48 4.17 Fri Apr 11 06:22:38 CEST 2014
49 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
50 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
51 in 5.18. What's so attractive about giving a shit about backwards
52 compatibility - I will never understand.
53
54 4.16 Sat Mar 8 16:49:05 CET 2014
55 - make sure EV::CHECK is available at all times.
56 - avoid a spurious warning when perl -w overrides "no warnings".
57 - use perl's signal implementation on WIN32.
58 - ensure extern "C" function pointers are used for externally-visible
59 pointers.
60 - (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
61 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
62 - (libev) in the absence of autoconf, do not use the clock syscall
63 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
64 doing clock_gettime in userspace).
65 - (ecb) work around memory barriers and volatile apparently both being
66 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
67
68 4.15 Fri Mar 1 12:15:53 CET 2013
69 - (libev) upgrade to 4.15 - too many changes to list.
70 - EV::run now returns a boolean.
71 - API version 5:1.
72 - document that cleanup watchers are not available via perl.
73 - cast I32 to int in error message printf.
74 - remove dependencies on librt and libpthreads on GNU/Linux.
75
76 4.11 Sat Feb 4 19:56:26 CET 2012
77 - (libev) implement memory fences for (obsolete) llvm-gcc.
78
79 4.10 Thu Jan 19 18:54:23 CET 2012
80 - (libev) fix a race where the workaround against the epoll fork
81 bugs caused signals to not be handled anymore.
82 - (libev) correct backend_fudge for most backends, and implement
83 a windows specific workaround to avoid looping because we call
84 both select and Sleep, both with different time resolutions.
85 - e_new wasn't declared static (causing very minor .so bloat).
86 - replace more old api names by new ones.
87
88 4.03 Tue Jan 11 14:51:05 CET 2011
89 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
90 links against -lpthread anyways - as a result, EV might now take
91 advantage of fast userspace clock_gettime implementations,
92 but also links against -lrt.
93 - (libev) lots of event port bug workarounds.
94 - (libev) officially support files in I/O watchers.
95 - (libev) new function ev_feed_signal.
96 - fix documentation parts still refering to the 3.x API.
97
98 4.02 Thu Dec 30 08:27:41 CET 2010
99 - the revents argument did not stringify correctly, as only the
100 numeric value was updated, while the string value was kept from
101 previous invocations.
102
103 4.01 Sun Dec 5 12:42:13 CET 2010
104 - fully support EV_COMPAT3=0.
105 - default_fork was stupidly defined as inline.
106 - ask cpan to upgrade AnyEvent if < 5.29.
107 - support EV_EXTRA_DEFS during configuration.
108 - support -DEV_NO_LOOPS for snakker build.
109
110 4.00 Mon Oct 25 13:30:09 CEST 2010
111 - many API changes, see the manual.
112 - (libev) lots and lots of bugfixes, see the ev documentation.
113 - fix a bug where inotify usage would parse the same event
114 multiple times, causing various forms of breakage.
115 - greatly reduce stack usage for inotify (8kb to <0.5kb).
116 - expose ev_depth and ev_verify via the XS API.
117 - implement ev_cleanup watchers.
118 - (libev) ev_embed_stop did not correctly stop the watcher.
119 - (libev) disable poll backend on AIX.
120 - (libev) rename EV_TIMEOUT to EV_TIMER.
121 - (libev) add section on accept() problems to the manpage.
122 - (libev) no child watchers on win32.
123 - make code more aliasing compliant, in case perl is ever
124 translated to C.
125 - document the EV::CHECK runtime unavailability.
126 - ported to minix 3.1.7.
127
128 3.9 Thu Dec 31 07:59:59 CET 2009
129 - disable t/07* under automatic testing.
130 - increase t/09* timeouts as netbsd has *horribly* broken
131 select/kevent that *usually* sleep >>0.6s instead of 0.3.
132 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
133 EV::BACKEND_ALL.
134 - (libev) signalfd is no longer used by default.
135 - (libev) backport inotify code to C89.
136 - (libev) inotify file descriptors could leak into child processes.
137 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
138 - (libev) take advantage of inotify_init1, if available.
139 - (libev) the signal handling pipe wasn't always initialised under windows.
140 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
141 - (libev) only replace ev_stat.prev when we detect an actual difference.
142
143 3.8 Sun Aug 9 15:30:10 CEST 2009
144 - implement $loop->signal/signal_ns.
145 - (libev) incompatible change: do not necessarily reset signal
146 handler to SIG_DFL when a sighandler is stopped.
147 - (libev) ev_default_destroy did not properly free or zero some
148 members, potentially causing crashes and memory corruption on
149 repated ev_default_destroy/ev_default_loop calls.
150 - (libev) take advantage of signalfd on GNU/Linux systems.
151 - (libev) document that the signal mask might be in an unspecified
152 state when using libev's signal handling.
153 - (libev) take advantage of some GNU/Linux calls to set
154 cloexec/nonblock on fd creation, to avoid race conditions.
155 - implement internal glue code to interface more efficiently
156 with AnyEvent.
157
158 3.7 Fri Jul 17 16:49:16 CEST 2009
159 - add EV::loop_verify and EV::loop_depth.
160 - use output filehandle for i/o watchers waiting
161 for EV_WRITE, otherwise input filehandle.
162 - use common schmorp.h header.
163 - add EV::Timer->remaining.
164 - allow for subclassing of EV::Loop (see the exciting
165 EV::Loop::Async module for an example).
166 - added EV::invoke_pending and EV::pending_count.
167
168 - (libev) ev_unloop and ev_loop wrongly used a global variable to
169 exit loops, instead of using a per-loop variable.
170 - (libev) the ev_set_io_collect_interval interpretation has changed.
171 - add new functionality: EV::invoke_pending, EV::pending_count.
172 - add $timer->remaining.
173 - add EV::loop_depth.
174 - (libev) calling unloop in fork/prepare watchers will no longer poll
175 for new events.
176 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
177 for slightly higher accuracy.
178 - (libev) actually 0-initialise struct sigaction when installing
179 signals.
180
181 3.6 Tue Apr 28 02:50:37 CEST 2009
182 - keepalive(0) could decrease the refcount of the loop
183 permanently.
184 - add ev_suspend/ev_resume, also make ev_now_update
185 accessible via the XS API.
186 - most EV::<eventtype> constants were missing and have been
187 added :/.
188 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
189 - (libev) multiple timers becoming ready within an event loop
190 iteration will be invoked in the "correct" order now.
191 - (libev) do not leave the event loop early just because we have
192 no active watchers, fixing a problem when embedding a kqueue
193 loop that has active kernel events but no registered watchers
194 (reported by blacksand blacksand).
195 - (libev) correctly zero the idx values for arrays, so destroying
196 and reinitialising the default loop actually works (patch by
197 Malek Hadj-Ali).
198 - (libev) new EV::CUSTOM revents flag for use by applications.
199 - (libev) add documentation section about priorites.
200 - (libev) add a glossary to the dcoumentation.
201 - (libev) extend the ev_fork description slightly.
202 - (libev) optimize a jump out of call_pending.
203 - t/03_keepalive could fail when there was no actual error.
204
205 3.53 Sun Feb 15 02:38:20 CET 2009
206 - (libev) on win32, the event loop creation could randomly fail
207 due to an initialised variable having the wrong value.
208 - (libev) probe for CLOCK_REALTIME support at runtime as well and
209 fall back to gettimeofday if there is an error, to support older
210 operating systems with newer header files/libraries.
211 - prefer gettimeofday over clock_gettime by default.
212
213 3.52 Wed Jan 7 21:46:14 CET 2009
214 - (libev) fix some issues in the select backend when in fd_set mode.
215 - (libev) due to a thinko, instead of disabling everything but
216 select on the borked OS X platform, everything but select was
217 allowed (reported by Emanuele Giaquinta).
218 - (libev) actually verify that local and remote port are matching in
219 libev's socketpair emulation, which makes denial-of-service
220 attacks harder (but not impossible - it's windows). Make sure
221 it even works under vista, which thinks that getpeer/sockname
222 should return fantasy port numbers.
223
224 3.51 Wed Dec 24 23:01:59 CET 2008
225 - do not cache the arguments passed to callbacks if the refcount
226 indicates that the callback has stolen them.
227 - (libev) try to avoid librt on GNU/Linux.
228 - (libev) check port_getn return value dfferently, might potentially
229 avoid problems.
230 - (libev) fix a bug with stat watchers possibly causing freezes.
231 - (libev) work around OS X 10.5 breaking poll, now select is the
232 only viable choice left on that pile of garbage.
233 - play tester whore: disable some tests that typically fail only
234 on cpan tester machines.
235
236 3.49 Wed Nov 19 11:26:53 CET 2008
237 - fix typos in manpage (Alex Efros).
238 - increase timing even further, for the ever-overloaded cpan-tester
239 machines, and to the detriment of everybody else who wants a fast
240 make test.
241 - possible 5.6 compatibility.
242 - (libev) use inotify even on buggy kernels, but don't rely on it.
243 - (libev) use inotify only as an added hint on network filesystems.
244
245 3.48 Thu Oct 30 09:09:48 CET 2008
246 - (libev) use a generation counter to detect spurious epoll events
247 and recreate the kernel in such a case (sorry, it's slow, but
248 I didn't design epoll...).
249 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
250 backend in some cases.
251 - (libev) use memset to initialise most arrays now and do away
252 with the init functions.
253 - speed up event callback invocation further (~15%), by
254 not creating the object reference each time.
255 - EV::sleep was documented, but not implemented. fun.
256
257 3.45 Tue Oct 21 22:20:39 CEST 2008
258 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
259 - (libev) ev_embed will now automatically follow fork.
260 - (libev) ev_once will now pass both io and timeout events to
261 the callback when both happen concurrently, instead of giving
262 one precedence.
263 - install C library documentation as EV::libev manpage (sorry, oesi).
264 - (libev) fix a minor performance bug in ev_stat handling.
265
266 3.44 Mon Sep 29 05:16:31 CEST 2008
267 - (libev) add EV::now_update and $loop->now_update.
268
269 3.431 Sun Jul 13 00:19:02 CEST 2008
270 - made the EV::embed callback optional again. reported by
271 Vladimir Timofeev.
272
273 3.43 Tue Jul 8 20:56:31 CEST 2008
274 - disabled warnings in EV.pm, the CHECK issue is now understood
275 and harmless.
276
277 3.42 Mon May 26 07:36:46 CEST 2008
278 - (libev) work around another bug in windows perls and
279 windows itself: failed connects do NOT set read or write
280 flags in select, but this version of libev will.
281
282 3.41 Thu May 22 01:39:40 CEST 2008
283 - (libev) fix many heap-related bugs (timers, periodics).
284 - (libev) improve timing stability of timers and periodics.
285 - expose ev_loop_verify to perl code.
286 - clarify documentation for periodic reschedule callbacks.
287 - verify that the passed callback argument is indeed a code
288 reference, for earlier error reporting and a nice calling
289 speed increase (as well as saving memory).
290
291 3.4 Tue May 20 21:51:55 CEST 2008
292 - (libev) work around both a windows bug and a bug in perl's
293 select on windows when not waiting for any file descriptors.
294 - bundle ev.pod into the tarball, just to increase its size
295 (and for the poor internetless person).
296
297 3.33 Sun May 18 12:43:04 CEST 2008
298 - (libev) use numerous enhancements such as a more
299 cache-friendly 4-heap and heap index caching for timers.

319
320 3.1 Sat Mar 8 11:41:14 CET 2008
321 - add ev_sync_* and ev_fork_* to EVAPI.h.
322 - provide EV::Embed->sweep method.

325 3.0 Mon Jan 28 13:23:11 CET 2008
326 - upgrade to libev-3.0.
327 - change child handler to incorporate tracing flag.
328
329 2.01 Mon Dec 31 01:59:19 CET 2007
330 - found a minor problem in the testsuite that is only
331 caught by new Test::Harness versions (reported by Andreas
332 König).
333
334 2.0 Sat Dec 22 17:47:03 CET 2007

339 - use a slightly different include file name strategy.
340 - get rid of (unused) libevent emulation.

358 - API version 3:0.
359 - reduced fudge factor to zero for select, poll, epoll
360 and kqueue: your system better be posix-compliant
361 even in its extensions :->
362 - improve long-term numerical stability in periodic watchers
363 by introducing a separate offset value instead of reusing at.
364 - recalculate real/monotonic clocks before blocking fully

414 1.2 Thu Nov 22 05:44:09 CET 2007
415 - disable kqueue by default on !netbsd, as its broken on freebsd,
416 darwin and openbsd and thus almost everywhere.
417 - add some allowance in t/01_timer.t for the uneven monotonic
418 vs. realtime clock tick on at least freebsd.
