3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 4.29 Fri Nov 22 15:34:29 CET 2019
7 - (libev) add io uring autoconf and non-autoconf detection,
8 the latter of which should disable io_uring compilation
9 on old systems.
10
11 4.28 Tue Nov 19 13:55:39 CET 2019
12 - (libev) fix ev_port backend, thanks to David H. Gutteridge for
13 - (libev) many bugfixes in linuxaio backend.
14 - (libev) experimental io uring interface.
15 reminding me to actually release the fix.
16 - try to name ev.h more explicitly, to hopefully improve portability.
17 - opportunistically round up wait times for poll and epoll backend,
18 to avoid unnecessary loop iterations.
19 - add build dependency on ev_linuxaio.c.
20 - quickly (re)-ported to minix 3.3 before minix crashed again.
21
22 4.27 Thu Jun 27 09:39:58 CEST 2019
23 - (libev) completely rewritten linuxaio backend, maybe
24 usable as a general-use backend.
25 - (libev) use more aggressive assertions to catch
26 more usage errors.
27 - allow users to re-enable assert() in case it is disabled
28 by perl (which is typically the case).
29
30 4.26 Mon Jun 24 23:39:40 CEST 2019
31 - (libev) included experimental linux aio backend.
32 - allow the linux aio backend to be used by default
33 only when explicitly configured during Makefile.PL time.
34
35 4.25 Fri Dec 21 08:04:26 CET 2018
36 - (libev) updated to libev 4.25, minor fixes and enhancements.
37 - document the requirement to "use EV" when using EV::MakeMaker.
38 - only use __register_atfork with glibc and uclibc, as musl
39 defines __linux__, but doesn't implement the linux standard
40 base ABI, nor makes itself detectable via a macro, both apparently
41 by design, winning the "broken by design 2016 award" - well done.
42 - correct EV::periodic example 24h after midnight -> one day after
43 midnight (reported by Felix Ostmann).
44
45 4.22 Sun Dec 20 02:34:39 CET 2015
46 - (libev) when epoll detects unremovable fds in the fd set, rebuild
47 only the epoll descriptor, not the signal pipe, to avoid
48 SIGPIPE in ev_async_send. This doesn't solve it on fork,
49 so document what needs to be done in ev_loop_fork
50 (analyzed by Benjamin Mahler).
51 - (libev) remove superfluous sys/timeb.h include on win32
52 (analyzed by Jason Madden).
53 - updated libecb.
54
55 4.21 Mon Jul 13 21:47:33 CEST 2015
56 - allow argument in timer->again.
57 - document timer->remaining.
58 - document default repeat value for timer->set.
59
60 4.20 Sat Jun 20 13:07:34 CEST 2015
61 - added stability canary support.
62 - truly rely on automatic configuration for clock_gettime and others.
63 unfortunately, this doesn't help with activeperl and similar perls,
64 which define _POSIX_TIMERS without actually implementing any of it.
65 - (libev, ecb) make it compile as C++ again.
66 - (libev) fix a potential aliasing issue when accessing watcher cbs.
67
68 4.18 Sat Sep 6 20:37:23 CEST 2014
69 - use slightly better weay to find includes, to support multiarch
70 on newer perls.
71
72 4.17 Fri Apr 11 06:22:38 CEST 2014
73 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
74 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
75 in 5.18. What's so attractive about giving a shit about backwards
76 compatibility - I will never understand.
77
78 4.16 Sat Mar 8 16:49:05 CET 2014
79 - make sure EV::CHECK is available at all times.
80 - avoid a spurious warning when perl -w overrides "no warnings".
81 - use perl's signal implementation on WIN32.
82 - ensure extern "C" function pointers are used for externally-visible
83 pointers.
84 - (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
85 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
86 - (libev) in the absence of autoconf, do not use the clock syscall
87 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
88 doing clock_gettime in userspace).
89 - (ecb) work around memory barriers and volatile apparently both being
90 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
91
92 4.15 Fri Mar 1 12:15:53 CET 2013
93 - (libev) upgrade to 4.15 - too many changes to list.
94 - EV::run now returns a boolean.
95 - API version 5:1.
96 - document that cleanup watchers are not available via perl.
97 - cast I32 to int in error message printf.
98 - remove dependencies on librt and libpthreads on GNU/Linux.
99
100 4.11 Sat Feb 4 19:56:26 CET 2012
101 - (libev) implement memory fences for (obsolete) llvm-gcc.
102
103 4.10 Thu Jan 19 18:54:23 CET 2012
104 - (libev) fix a race where the workaround against the epoll fork
105 bugs caused signals to not be handled anymore.
106 - (libev) correct backend_fudge for most backends, and implement
107 a windows specific workaround to avoid looping because we call
108 both select and Sleep, both with different time resolutions.
109 - e_new wasn't declared static (causing very minor .so bloat).
110 - replace more old api names by new ones.
111
112 4.03 Tue Jan 11 14:51:05 CET 2011
113 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
114 links against -lpthread anyways - as a result, EV might now take
115 advantage of fast userspace clock_gettime implementations,
116 but also links against -lrt.
117 - (libev) lots of event port bug workarounds.
118 - (libev) officially support files in I/O watchers.
119 - (libev) new function ev_feed_signal.
120 - fix documentation parts still refering to the 3.x API.
121
122 4.02 Thu Dec 30 08:27:41 CET 2010
123 - the revents argument did not stringify correctly, as only the
124 numeric value was updated, while the string value was kept from
125 previous invocations.
126
127 4.01 Sun Dec 5 12:42:13 CET 2010
128 - fully support EV_COMPAT3=0.
129 - default_fork was stupidly defined as inline.
130 - ask cpan to upgrade AnyEvent if < 5.29.
131 - support EV_EXTRA_DEFS during configuration.
132 - support -DEV_NO_LOOPS for snakker build.
133
134 4.00 Mon Oct 25 13:30:09 CEST 2010
135 - many API changes, see the manual.
136 - (libev) lots and lots of bugfixes, see the ev documentation.
137 - fix a bug where inotify usage would parse the same event
138 multiple times, causing various forms of breakage.
139 - greatly reduce stack usage for inotify (8kb to <0.5kb).
140 - expose ev_depth and ev_verify via the XS API.
141 - implement ev_cleanup watchers.
142 - (libev) ev_embed_stop did not correctly stop the watcher.
143 - (libev) disable poll backend on AIX.
144 - (libev) rename EV_TIMEOUT to EV_TIMER.
145 - (libev) add section on accept() problems to the manpage.
146 - (libev) no child watchers on win32.
147 - make code more aliasing compliant, in case perl is ever
148 translated to C.
149 - document the EV::CHECK runtime unavailability.
150 - ported to minix 3.1.7.
151
152 3.9 Thu Dec 31 07:59:59 CET 2009
153 - disable t/07* under automatic testing.
154 - increase t/09* timeouts as netbsd has *horribly* broken
155 select/kevent that *usually* sleep >>0.6s instead of 0.3.
156 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
157 EV::BACKEND_ALL.
158 - (libev) signalfd is no longer used by default.
159 - (libev) backport inotify code to C89.
160 - (libev) inotify file descriptors could leak into child processes.
161 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
162 - (libev) take advantage of inotify_init1, if available.
163 - (libev) the signal handling pipe wasn't always initialised under windows.
164 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
165 - (libev) only replace ev_stat.prev when we detect an actual difference.
166
167 3.8 Sun Aug 9 15:30:10 CEST 2009
168 - implement $loop->signal/signal_ns.
169 - (libev) incompatible change: do not necessarily reset signal
170 handler to SIG_DFL when a sighandler is stopped.
171 - (libev) ev_default_destroy did not properly free or zero some
172 members, potentially causing crashes and memory corruption on
173 repated ev_default_destroy/ev_default_loop calls.
174 - (libev) take advantage of signalfd on GNU/Linux systems.
175 - (libev) document that the signal mask might be in an unspecified
176 state when using libev's signal handling.
177 - (libev) take advantage of some GNU/Linux calls to set
178 cloexec/nonblock on fd creation, to avoid race conditions.
179 - implement internal glue code to interface more efficiently
180 with AnyEvent.
181
182 3.7 Fri Jul 17 16:49:16 CEST 2009
183 - add EV::loop_verify and EV::loop_depth.
184 - use output filehandle for i/o watchers waiting
185 for EV_WRITE, otherwise input filehandle.
186 - use common schmorp.h header.
187 - add EV::Timer->remaining.
188 - allow for subclassing of EV::Loop (see the exciting
189 EV::Loop::Async module for an example).
190 - added EV::invoke_pending and EV::pending_count.
191
192 - (libev) ev_unloop and ev_loop wrongly used a global variable to
193 exit loops, instead of using a per-loop variable.
194 - (libev) the ev_set_io_collect_interval interpretation has changed.
195 - add new functionality: EV::invoke_pending, EV::pending_count.
196 - add $timer->remaining.
197 - add EV::loop_depth.
198 - (libev) calling unloop in fork/prepare watchers will no longer poll
199 for new events.
200 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
201 for slightly higher accuracy.
202 - (libev) actually 0-initialise struct sigaction when installing
203 signals.
204
205 3.6 Tue Apr 28 02:50:37 CEST 2009
206 - keepalive(0) could decrease the refcount of the loop
207 permanently.
208 - add ev_suspend/ev_resume, also make ev_now_update
209 accessible via the XS API.
210 - most EV::<eventtype> constants were missing and have been
211 added :/.
212 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
213 - (libev) multiple timers becoming ready within an event loop
214 iteration will be invoked in the "correct" order now.
215 - (libev) do not leave the event loop early just because we have
216 no active watchers, fixing a problem when embedding a kqueue
217 loop that has active kernel events but no registered watchers
218 (reported by blacksand blacksand).
219 - (libev) correctly zero the idx values for arrays, so destroying
220 and reinitialising the default loop actually works (patch by
221 Malek Hadj-Ali).
222 - (libev) new EV::CUSTOM revents flag for use by applications.
223 - (libev) add documentation section about priorites.
224 - (libev) add a glossary to the dcoumentation.
225 - (libev) extend the ev_fork description slightly.
226 - (libev) optimize a jump out of call_pending.
227 - t/03_keepalive could fail when there was no actual error.
228
229 3.53 Sun Feb 15 02:38:20 CET 2009
230 - (libev) on win32, the event loop creation could randomly fail
231 due to an initialised variable having the wrong value.
232 - (libev) probe for CLOCK_REALTIME support at runtime as well and
233 fall back to gettimeofday if there is an error, to support older
234 operating systems with newer header files/libraries.
235 - prefer gettimeofday over clock_gettime by default.
236
237 3.52 Wed Jan 7 21:46:14 CET 2009
238 - (libev) fix some issues in the select backend when in fd_set mode.
239 - (libev) due to a thinko, instead of disabling everything but
240 select on the borked OS X platform, everything but select was
241 allowed (reported by Emanuele Giaquinta).
242 - (libev) actually verify that local and remote port are matching in
243 libev's socketpair emulation, which makes denial-of-service
244 attacks harder (but not impossible - it's windows). Make sure
245 it even works under vista, which thinks that getpeer/sockname
246 should return fantasy port numbers.
247
248 3.51 Wed Dec 24 23:01:59 CET 2008
249 - do not cache the arguments passed to callbacks if the refcount
250 indicates that the callback has stolen them.
251 - (libev) try to avoid librt on GNU/Linux.
252 - (libev) check port_getn return value dfferently, might potentially
253 avoid problems.
254 - (libev) fix a bug with stat watchers possibly causing freezes.
255 - (libev) work around OS X 10.5 breaking poll, now select is the
256 only viable choice left on that pile of garbage.
257 - play tester whore: disable some tests that typically fail only
258 on cpan tester machines.
259
260 3.49 Wed Nov 19 11:26:53 CET 2008
261 - fix typos in manpage (Alex Efros).
262 - increase timing even further, for the ever-overloaded cpan-tester
263 machines, and to the detriment of everybody else who wants a fast
264 make test.
265 - possible 5.6 compatibility.
266 - (libev) use inotify even on buggy kernels, but don't rely on it.
267 - (libev) use inotify only as an added hint on network filesystems.
268
269 3.48 Thu Oct 30 09:09:48 CET 2008
270 - (libev) use a generation counter to detect spurious epoll events
271 and recreate the kernel in such a case (sorry, it's slow, but
272 I didn't design epoll...).
273 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
274 backend in some cases.
275 - (libev) use memset to initialise most arrays now and do away
276 with the init functions.
277 - speed up event callback invocation further (~15%), by
278 not creating the object reference each time.
279 - EV::sleep was documented, but not implemented. fun.
280
281 3.45 Tue Oct 21 22:20:39 CEST 2008
282 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
283 - (libev) ev_embed will now automatically follow fork.
284 - (libev) ev_once will now pass both io and timeout events to
285 the callback when both happen concurrently, instead of giving
286 one precedence.
287 - install C library documentation as EV::libev manpage (sorry, oesi).
288 - (libev) fix a minor performance bug in ev_stat handling.
289
290 3.44 Mon Sep 29 05:16:31 CEST 2008
291 - (libev) add EV::now_update and $loop->now_update.
292
293 3.431 Sun Jul 13 00:19:02 CEST 2008
294 - made the EV::embed callback optional again. reported by
295 Vladimir Timofeev.
296
297 3.43 Tue Jul 8 20:56:31 CEST 2008
298 - disabled warnings in EV.pm, the CHECK issue is now understood
299 and harmless.
300
301 3.42 Mon May 26 07:36:46 CEST 2008
302 - (libev) work around another bug in windows perls and
303 windows itself: failed connects do NOT set read or write
304 flags in select, but this version of libev will.
305
306 3.41 Thu May 22 01:39:40 CEST 2008
307 - (libev) fix many heap-related bugs (timers, periodics).
308 - (libev) improve timing stability of timers and periodics.
309 - expose ev_loop_verify to perl code.
310 - clarify documentation for periodic reschedule callbacks.
311 - verify that the passed callback argument is indeed a code
312 reference, for earlier error reporting and a nice calling
313 speed increase (as well as saving memory).
314
315 3.4 Tue May 20 21:51:55 CEST 2008
316 - (libev) work around both a windows bug and a bug in perl's
317 select on windows when not waiting for any file descriptors.
318 - bundle ev.pod into the tarball, just to increase its size
319 (and for the poor internetless person).
320
321 3.33 Sun May 18 12:43:04 CEST 2008
322 - (libev) use numerous enhancements such as a more
323 cache-friendly 4-heap and heap index caching for timers.

343
344 3.1 Sat Mar 8 11:41:14 CET 2008
345 - add ev_sync_* and ev_fork_* to EVAPI.h.
346 - provide EV::Embed->sweep method.

348
349 3.0 Mon Jan 28 13:23:11 CET 2008
350 - upgrade to libev-3.0.
351 - change child handler to incorporate tracing flag.
352
353 2.01 Mon Dec 31 01:59:19 CET 2007
354 - found a minor problem in the testsuite that is only
355 caught by new Test::Harness versions (reported by Andreas
356 König).
357
358 2.0 Sat Dec 22 17:47:03 CET 2007

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

379 - optimise start/stop when the fd hasn't changed.
380
381 1.8 Tue Dec 11 22:17:46 CET 2007
382 - API version 3:0.
383 - reduced fudge factor to zero for select, poll, epoll
384 and kqueue: your system better be posix-compliant
385 even in its extensions :->
386 - improve long-term numerical stability in periodic watchers
387 by introducing a separate offset value instead of reusing at.
388 - recalculate real/monotonic clocks before blocking fully

437
438 1.2 Thu Nov 22 05:44:09 CET 2007
439 - disable kqueue by default on !netbsd, as its broken on freebsd,
440 darwin and openbsd and thus almost everywhere.
441 - add some allowance in t/01_timer.t for the uneven monotonic
442 vs. realtime clock tick on at least freebsd.
443 - add -lsocket -lnsl on solaris in case the perl guy forgot to
