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

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

343
344 3.0 Mon Jan 28 13:23:11 CET 2008
345 - upgrade to libev-3.0.
346 - change child handler to incorporate tracing flag.
347
348 2.01 Mon Dec 31 01:59:19 CET 2007
349 - found a minor problem in the testsuite that is only
350 caught by new Test::Harness versions (reported by Andreas
351 König).
352
353 2.0 Sat Dec 22 17:47:03 CET 2007

375
376 1.8 Tue Dec 11 22:17:46 CET 2007
377 - API version 3:0.
378 - reduced fudge factor to zero for select, poll, epoll
379 and kqueue: your system better be posix-compliant
380 even in its extensions :->
381 - improve long-term numerical stability in periodic watchers
382 by introducing a separate offset value instead of reusing at.
383 - recalculate real/monotonic clocks before blocking fully

432
433 1.2 Thu Nov 22 05:44:09 CET 2007
434 - disable kqueue by default on !netbsd, as its broken on freebsd,
435 darwin and openbsd and thus almost everywhere.
436 - add some allowance in t/01_timer.t for the uneven monotonic
437 vs. realtime clock tick on at least freebsd.
438 - add -lsocket -lnsl on solaris in case the perl guy forgot to
