64.33 Wed Mar 18 13:31:12 CET 2020
7 - the enable assertion makefile question failed to enable
8 assertions due to a typo.
9 - try harder to avoid perl's assert () which does not actually
10 behave correctly.
11 - updated libecb to make it compile under more windows environments.
12
134.32 Fri Jan 24 14:21:35 CET 2020
14 - (libev) fixed a bug introduced in 4.31 when timerfds and signalfds were
15 used at the same time.
16 - (libev) 0 is now allowed as requested event mask in io watchers.
17 - (libev) once-per-minute wakeups will now be optimized away when
18 timerfds are available
19 - use the new ev_io_modify in EV::IO->events, instead of the potentially
20 slower ev_io_set.
21 - add a bunch of mutator methods, mostly untested(!): EV::Timer->repeat,
22 EV::Periodic->offset, EV::Periodic->interval,
23 EV::Periodic->reschedule_cb.
24 - minor optimisations and bugfixes.
25
264.31 Fri Dec 20 21:57:00 CET 2019
27 - (libev) handle backends with minimum wait time a bit better by
28 not waiting in the presence of already-expired timers
29 (behaviour reported by Felipe Gasper).
30 - (libev) use timerfd to detect timejumps.
31 - (libev) new loop flag: EVFLAG_NOTIMERFD.
32
334.30 Fri Nov 22 21:00:00 CET 2019
34 - (libev) use a different and hopefully even more portable
35 test to disable io_uring when header files are too old,
36 by directly testing LINUX_VERSION_CODE.
37 - (libev) fix a bug in the io_uring backend that polled the wrong
38 backend fd, causing it to not work in many cases.
39
404.29 Fri Nov 22 15:34:29 CET 2019
41 - (libev) add io uring autoconf and non-autoconf detection,
42 the latter of which should disable io_uring compilation
43 on old systems.
44
454.28 Tue Nov 19 13:55:39 CET 2019
46 - (libev) fix ev_port backend, thanks to David H. Gutteridge for
47 - (libev) many bugfixes in linuxaio backend.
48 - (libev) experimental io uring interface.
49 reminding me to actually release the fix.
50 - try to name ev.h more explicitly, to hopefully improve portability.
51 - opportunistically round up wait times for poll and epoll backend,
52 to avoid unnecessary loop iterations.
53 - add build dependency on ev_linuxaio.c.
54 - quickly (re)-ported to minix 3.3 before minix crashed again.
55
564.27 Thu Jun 27 09:39:58 CEST 2019
57 - (libev) completely rewritten linuxaio backend, maybe
58 usable as a general-use backend.
59 - (libev) use more aggressive assertions to catch
60 more usage errors.
61 - allow users to re-enable assert() in case it is disabled
62 by perl (which is typically the case).
63
644.26 Mon Jun 24 23:39:40 CEST 2019
65 - (libev) included experimental linux aio backend.
66 - allow the linux aio backend to be used by default
67 only when explicitly configured during Makefile.PL time.
68
694.25 Fri Dec 21 08:04:26 CET 2018
70 - (libev) updated to libev 4.25, minor fixes and enhancements.
71 - document the requirement to "use EV" when using EV::MakeMaker.
72 - only use __register_atfork with glibc and uclibc, as musl
73 defines __linux__, but doesn't implement the linux standard
74 base ABI, nor makes itself detectable via a macro, both apparently
75 by design, winning the "broken by design 2016 award" - well done.
76 - correct EV::periodic example 24h after midnight -> one day after
77 midnight (reported by Felix Ostmann).
78
794.22 Sun Dec 20 02:34:39 CET 2015
80 - (libev) when epoll detects unremovable fds in the fd set, rebuild
81 only the epoll descriptor, not the signal pipe, to avoid
82 SIGPIPE in ev_async_send. This doesn't solve it on fork,
83 so document what needs to be done in ev_loop_fork
84 (analyzed by Benjamin Mahler).
85 - (libev) remove superfluous sys/timeb.h include on win32
86 (analyzed by Jason Madden).
87 - updated libecb.
88
894.21 Mon Jul 13 21:47:33 CEST 2015
90 - allow argument in timer->again.
91 - document timer->remaining.
92 - document default repeat value for timer->set.
93
944.20 Sat Jun 20 13:07:34 CEST 2015
95 - added stability canary support.
96 - truly rely on automatic configuration for clock_gettime and others.
97 unfortunately, this doesn't help with activeperl and similar perls,
98 which define _POSIX_TIMERS without actually implementing any of it.
99 - (libev, ecb) make it compile as C++ again.
100 - (libev) fix a potential aliasing issue when accessing watcher cbs.
101
1024.18 Sat Sep 6 20:37:23 CEST 2014
103 - use slightly better weay to find includes, to support multiarch
104 on newer perls.
105
1064.17 Fri Apr 11 06:22:38 CEST 2014
107 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
108 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
109 in 5.18. What's so attractive about giving a shit about backwards
110 compatibility - I will never understand.
111
1124.16 Sat Mar 8 16:49:05 CET 2014
113 - make sure EV::CHECK is available at all times.
114 - avoid a spurious warning when perl -w overrides "no warnings".
115 - use perl's signal implementation on WIN32.
116 - ensure extern "C" function pointers are used for externally-visible
117 pointers.
118 - (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
119 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
120 - (libev) in the absence of autoconf, do not use the clock syscall
121 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
122 doing clock_gettime in userspace).
123 - (ecb) work around memory barriers and volatile apparently both being
124 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
125
1264.15 Fri Mar 1 12:15:53 CET 2013
127 - (libev) upgrade to 4.15 - too many changes to list.
128 - EV::run now returns a boolean.
129 - API version 5:1.
130 - document that cleanup watchers are not available via perl.
131 - cast I32 to int in error message printf.
132 - remove dependencies on librt and libpthreads on GNU/Linux.
133
1344.11 Sat Feb 4 19:56:26 CET 2012
135 - (libev) implement memory fences for (obsolete) llvm-gcc.
136
1374.10 Thu Jan 19 18:54:23 CET 2012
138 - (libev) fix a race where the workaround against the epoll fork
139 bugs caused signals to not be handled anymore.
140 - (libev) correct backend_fudge for most backends, and implement
141 a windows specific workaround to avoid looping because we call
142 both select and Sleep, both with different time resolutions.
143 - e_new wasn't declared static (causing very minor .so bloat).
144 - replace more old api names by new ones.
145
1464.03 Tue Jan 11 14:51:05 CET 2011
147 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
148 links against -lpthread anyways - as a result, EV might now take
149 advantage of fast userspace clock_gettime implementations,
150 but also links against -lrt.
151 - (libev) lots of event port bug workarounds.
152 - (libev) officially support files in I/O watchers.
153 - (libev) new function ev_feed_signal.
154 - fix documentation parts still refering to the 3.x API.
155
1564.02 Thu Dec 30 08:27:41 CET 2010
157 - the revents argument did not stringify correctly, as only the
158 numeric value was updated, while the string value was kept from
159 previous invocations.
160
1614.01 Sun Dec 5 12:42:13 CET 2010
162 - fully support EV_COMPAT3=0.
163 - default_fork was stupidly defined as inline.
164 - ask cpan to upgrade AnyEvent if < 5.29.
165 - support EV_EXTRA_DEFS during configuration.
166 - support -DEV_NO_LOOPS for snakker build.
167
1684.00 Mon Oct 25 13:30:09 CEST 2010
169 - many API changes, see the manual.
170 - (libev) lots and lots of bugfixes, see the ev documentation.
171 - fix a bug where inotify usage would parse the same event
172 multiple times, causing various forms of breakage.
173 - greatly reduce stack usage for inotify (8kb to <0.5kb).
174 - expose ev_depth and ev_verify via the XS API.
175 - implement ev_cleanup watchers.
176 - (libev) ev_embed_stop did not correctly stop the watcher.
177 - (libev) disable poll backend on AIX.
178 - (libev) rename EV_TIMEOUT to EV_TIMER.
179 - (libev) add section on accept() problems to the manpage.
180 - (libev) no child watchers on win32.
181 - make code more aliasing compliant, in case perl is ever
182 translated to C.
183 - document the EV::CHECK runtime unavailability.
184 - ported to minix 3.1.7.
185
1863.9 Thu Dec 31 07:59:59 CET 2009
187 - disable t/07* under automatic testing.
188 - increase t/09* timeouts as netbsd has *horribly* broken
189 select/kevent that *usually* sleep >>0.6s instead of 0.3.
190 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
191 EV::BACKEND_ALL.
192 - (libev) signalfd is no longer used by default.
193 - (libev) backport inotify code to C89.
194 - (libev) inotify file descriptors could leak into child processes.
195 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
196 - (libev) take advantage of inotify_init1, if available.
197 - (libev) the signal handling pipe wasn't always initialised under windows.
198 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
199 - (libev) only replace ev_stat.prev when we detect an actual difference.
200
2013.8 Sun Aug 9 15:30:10 CEST 2009
202 - implement $loop->signal/signal_ns.
203 - (libev) incompatible change: do not necessarily reset signal
204 handler to SIG_DFL when a sighandler is stopped.
205 - (libev) ev_default_destroy did not properly free or zero some
206 members, potentially causing crashes and memory corruption on
207 repated ev_default_destroy/ev_default_loop calls.
208 - (libev) take advantage of signalfd on GNU/Linux systems.
209 - (libev) document that the signal mask might be in an unspecified
210 state when using libev's signal handling.
211 - (libev) take advantage of some GNU/Linux calls to set
212 cloexec/nonblock on fd creation, to avoid race conditions.
213 - implement internal glue code to interface more efficiently
214 with AnyEvent.
215
2163.7 Fri Jul 17 16:49:16 CEST 2009
217 - add EV::loop_verify and EV::loop_depth.
218 - use output filehandle for i/o watchers waiting
219 for EV_WRITE, otherwise input filehandle.
220 - use common schmorp.h header.
221 - add EV::Timer->remaining.
222 - allow for subclassing of EV::Loop (see the exciting
223 EV::Loop::Async module for an example).
224 - added EV::invoke_pending and EV::pending_count.
225
226 - (libev) ev_unloop and ev_loop wrongly used a global variable to
227 exit loops, instead of using a per-loop variable.
228 - (libev) the ev_set_io_collect_interval interpretation has changed.
229 - add new functionality: EV::invoke_pending, EV::pending_count.
230 - add $timer->remaining.
231 - add EV::loop_depth.
232 - (libev) calling unloop in fork/prepare watchers will no longer poll
233 for new events.
234 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
235 for slightly higher accuracy.
236 - (libev) actually 0-initialise struct sigaction when installing
237 signals.
238
2393.6 Tue Apr 28 02:50:37 CEST 2009
240 - keepalive(0) could decrease the refcount of the loop
241 permanently.
242 - add ev_suspend/ev_resume, also make ev_now_update
243 accessible via the XS API.
244 - most EV::<eventtype> constants were missing and have been
245 added :/.
246 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
247 - (libev) multiple timers becoming ready within an event loop
248 iteration will be invoked in the "correct" order now.
249 - (libev) do not leave the event loop early just because we have
250 no active watchers, fixing a problem when embedding a kqueue
251 loop that has active kernel events but no registered watchers
252 (reported by blacksand blacksand).
253 - (libev) correctly zero the idx values for arrays, so destroying
254 and reinitialising the default loop actually works (patch by
255 Malek Hadj-Ali).
256 - (libev) new EV::CUSTOM revents flag for use by applications.
257 - (libev) add documentation section about priorites.
258 - (libev) add a glossary to the dcoumentation.
259 - (libev) extend the ev_fork description slightly.
260 - (libev) optimize a jump out of call_pending.
261 - t/03_keepalive could fail when there was no actual error.
262
2633.53 Sun Feb 15 02:38:20 CET 2009
264 - (libev) on win32, the event loop creation could randomly fail
265 due to an initialised variable having the wrong value.
266 - (libev) probe for CLOCK_REALTIME support at runtime as well and
267 fall back to gettimeofday if there is an error, to support older
268 operating systems with newer header files/libraries.
269 - prefer gettimeofday over clock_gettime by default.
270
2713.52 Wed Jan 7 21:46:14 CET 2009
272 - (libev) fix some issues in the select backend when in fd_set mode.
273 - (libev) due to a thinko, instead of disabling everything but
274 select on the borked OS X platform, everything but select was
275 allowed (reported by Emanuele Giaquinta).
276 - (libev) actually verify that local and remote port are matching in
277 libev's socketpair emulation, which makes denial-of-service
278 attacks harder (but not impossible - it's windows). Make sure
279 it even works under vista, which thinks that getpeer/sockname
280 should return fantasy port numbers.
281
2823.51 Wed Dec 24 23:01:59 CET 2008
283 - do not cache the arguments passed to callbacks if the refcount
284 indicates that the callback has stolen them.
285 - (libev) try to avoid librt on GNU/Linux.
286 - (libev) check port_getn return value dfferently, might potentially
287 avoid problems.
288 - (libev) fix a bug with stat watchers possibly causing freezes.
289 - (libev) work around OS X 10.5 breaking poll, now select is the
290 only viable choice left on that pile of garbage.
291 - play tester whore: disable some tests that typically fail only
292 on cpan tester machines.
293
2943.49 Wed Nov 19 11:26:53 CET 2008
295 - fix typos in manpage (Alex Efros).
296 - increase timing even further, for the ever-overloaded cpan-tester
297 machines, and to the detriment of everybody else who wants a fast
298 make test.
299 - possible 5.6 compatibility.
300 - (libev) use inotify even on buggy kernels, but don't rely on it.
301 - (libev) use inotify only as an added hint on network filesystems.
302
3033.48 Thu Oct 30 09:09:48 CET 2008
304 - (libev) use a generation counter to detect spurious epoll events
305 and recreate the kernel in such a case (sorry, it's slow, but
306 I didn't design epoll...).
307 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
308 backend in some cases.
309 - (libev) use memset to initialise most arrays now and do away
310 with the init functions.
311 - speed up event callback invocation further (~15%), by
312 not creating the object reference each time.
313 - EV::sleep was documented, but not implemented. fun.
314
3153.45 Tue Oct 21 22:20:39 CEST 2008
316 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
317 - (libev) ev_embed will now automatically follow fork.
318 - (libev) ev_once will now pass both io and timeout events to
319 the callback when both happen concurrently, instead of giving
320 one precedence.
321 - install C library documentation as EV::libev manpage (sorry, oesi).
322 - (libev) fix a minor performance bug in ev_stat handling.
323
3243.44 Mon Sep 29 05:16:31 CEST 2008
325 - (libev) add EV::now_update and $loop->now_update.
326
3273.431 Sun Jul 13 00:19:02 CEST 2008
328 - made the EV::embed callback optional again. reported by
329 Vladimir Timofeev.
330
3313.43 Tue Jul 8 20:56:31 CEST 2008
332 - disabled warnings in EV.pm, the CHECK issue is now understood
333 and harmless.
334
3353.42 Mon May 26 07:36:46 CEST 2008
336 - (libev) work around another bug in windows perls and
337 windows itself: failed connects do NOT set read or write
338 flags in select, but this version of libev will.
339
3403.41 Thu May 22 01:39:40 CEST 2008
341 - (libev) fix many heap-related bugs (timers, periodics).
342 - (libev) improve timing stability of timers and periodics.
343 - expose ev_loop_verify to perl code.
344 - clarify documentation for periodic reschedule callbacks.
345 - verify that the passed callback argument is indeed a code
346 reference, for earlier error reporting and a nice calling
347 speed increase (as well as saving memory).
348
3493.4 Tue May 20 21:51:55 CEST 2008
350 - (libev) work around both a windows bug and a bug in perl's
351 select on windows when not waiting for any file descriptors.
352 - bundle ev.pod into the tarball, just to increase its size
353 (and for the poor internetless person).
354
3553.33 Sun May 18 12:43:04 CEST 2008
356 - (libev) use numerous enhancements such as a more
357 cache-friendly 4-heap and heap index caching for timers.
358 - remove undocumented ev_timer->at accessor.
359
3603.31 Wed Apr 16 20:48:59 CEST 2008

379 - add ev_sync_* and ev_fork_* to EVAPI.h.
380 - provide EV::Embed->sweep method.

382
3833.0 Mon Jan 28 13:23:11 CET 2008
384 - upgrade to libev-3.0.
385 - change child handler to incorporate tracing flag.
386
3872.01 Mon Dec 31 01:59:19 CET 2007
388 - found a minor problem in the testsuite that is only
389 caught by new Test::Harness versions (reported by Andreas
390 König).
391
3922.0 Sat Dec 22 17:47:03 CET 2007
