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

327
328 3.1 Sat Mar 8 11:41:14 CET 2008
329 - add ev_sync_* and ev_fork_* to EVAPI.h.
330 - provide EV::Embed->sweep method.

333 3.0 Mon Jan 28 13:23:11 CET 2008
334 - upgrade to libev-3.0.
335 - change child handler to incorporate tracing flag.
336
337 2.01 Mon Dec 31 01:59:19 CET 2007
338 - found a minor problem in the testsuite that is only
339 caught by new Test::Harness versions (reported by Andreas
340 König).
341
342 2.0 Sat Dec 22 17:47:03 CET 2007

366 - API version 3:0.
367 - reduced fudge factor to zero for select, poll, epoll
368 and kqueue: your system better be posix-compliant
369 even in its extensions :->
370 - improve long-term numerical stability in periodic watchers
371 by introducing a separate offset value instead of reusing at.
372 - recalculate real/monotonic clocks before blocking fully

422 1.2 Thu Nov 22 05:44:09 CET 2007
423 - disable kqueue by default on !netbsd, as its broken on freebsd,
424 darwin and openbsd and thus almost everywhere.
425 - add some allowance in t/01_timer.t for the uneven monotonic
426 vs. realtime clock tick on at least freebsd.
427 - add -lsocket -lnsl on solaris in case the perl guy forgot to
