2 2
3Changes marked with (libev) are changes in libev, and have more
4documentation in the libev Changes file.
5
6 - try to name ev.h more explicitly, to hopefully improve portability.
7
84.27 Thu Jun 27 09:39:58 CEST 2019
9 - (libev) completely rewritten linuxaio backend, maybe
10 usable as a general-use backend.
11 - (libev) use more aggressive assertions to catch
12 more usage errors.
13 - allow users to re-enable assert() in case it is disabled
14 by perl (which is typically the case).
15
164.26 Mon Jun 24 23:39:40 CEST 2019
17 - (libev) included experimental linux aio backend.
18 - allow the linux aio backend to be used by default
19 only when explicitly configured during Makefile.PL time.
20
214.25 Fri Dec 21 08:04:26 CET 2018
22 - (libev) updated to libev 4.25, minor fixes and enhancements.
23 - document the requirement to "use EV" when using EV::MakeMaker.
24 - only use __register_atfork with glibc and uclibc, as musl
25 defines __linux__, but doesn't implement the linux standard
26 base ABI, nor makes itself detectable via a macro, both apparently
27 by design, winning the "broken by design 2016 award" - well done.
28 - correct EV::periodic example 24h after midnight -> one day after
29 midnight (reported by Felix Ostmann).
30
314.22 Sun Dec 20 02:34:39 CET 2015
32 - (libev) when epoll detects unremovable fds in the fd set, rebuild
33 only the epoll descriptor, not the signal pipe, to avoid
34 SIGPIPE in ev_async_send. This doesn't solve it on fork,
35 so document what needs to be done in ev_loop_fork
36 (analyzed by Benjamin Mahler).
37 - (libev) remove superfluous sys/timeb.h include on win32
38 (analyzed by Jason Madden).
39 - updated libecb.
40
414.21 Mon Jul 13 21:47:33 CEST 2015
42 - allow argument in timer->again.
43 - document timer->remaining.
44 - document default repeat value for timer->set.
45
464.20 Sat Jun 20 13:07:34 CEST 2015
47 - added stability canary support.
48 - truly rely on automatic configuration for clock_gettime and others.
49 unfortunately, this doesn't help with activeperl and similar perls,
50 which define _POSIX_TIMERS without actually implementing any of it.
51 - (libev, ecb) make it compile as C++ again.
52 - (libev) fix a potential aliasing issue when accessing watcher cbs.
53
544.18 Sat Sep 6 20:37:23 CEST 2014
55 - use slightly better weay to find includes, to support multiarch
56 on newer perls.
57
584.17 Fri Apr 11 06:22:38 CEST 2014
59 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
60 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
61 in 5.18. What's so attractive about giving a shit about backwards
62 compatibility - I will never understand.
63
644.16 Sat Mar 8 16:49:05 CET 2014
65 - make sure EV::CHECK is available at all times.
66 - avoid a spurious warning when perl -w overrides "no warnings".
67 - use perl's signal implementation on WIN32.
68 - ensure extern "C" function pointers are used for externally-visible
69 pointers.
70 - (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
71 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
72 - (libev) in the absence of autoconf, do not use the clock syscall
73 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
74 doing clock_gettime in userspace).
75 - (ecb) work around memory barriers and volatile apparently both being
76 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
77
784.15 Fri Mar 1 12:15:53 CET 2013
79 - (libev) upgrade to 4.15 - too many changes to list.
80 - EV::run now returns a boolean.
81 - API version 5:1.
82 - document that cleanup watchers are not available via perl.
83 - cast I32 to int in error message printf.
84 - remove dependencies on librt and libpthreads on GNU/Linux.
85
864.11 Sat Feb 4 19:56:26 CET 2012
87 - (libev) implement memory fences for (obsolete) llvm-gcc.
88
894.10 Thu Jan 19 18:54:23 CET 2012
90 - (libev) fix a race where the workaround against the epoll fork
91 bugs caused signals to not be handled anymore.
92 - (libev) correct backend_fudge for most backends, and implement
93 a windows specific workaround to avoid looping because we call
94 both select and Sleep, both with different time resolutions.
95 - e_new wasn't declared static (causing very minor .so bloat).
96 - replace more old api names by new ones.
97
984.03 Tue Jan 11 14:51:05 CET 2011
99 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
100 links against -lpthread anyways - as a result, EV might now take
101 advantage of fast userspace clock_gettime implementations,
102 but also links against -lrt.
103 - (libev) lots of event port bug workarounds.
104 - (libev) officially support files in I/O watchers.
105 - (libev) new function ev_feed_signal.
106 - fix documentation parts still refering to the 3.x API.
107
1084.02 Thu Dec 30 08:27:41 CET 2010
109 - the revents argument did not stringify correctly, as only the
110 numeric value was updated, while the string value was kept from
111 previous invocations.
112
1134.01 Sun Dec 5 12:42:13 CET 2010
114 - fully support EV_COMPAT3=0.
115 - default_fork was stupidly defined as inline.
116 - ask cpan to upgrade AnyEvent if < 5.29.
117 - support EV_EXTRA_DEFS during configuration.
118 - support -DEV_NO_LOOPS for snakker build.
119
1204.00 Mon Oct 25 13:30:09 CEST 2010
121 - many API changes, see the manual.
122 - (libev) lots and lots of bugfixes, see the ev documentation.
123 - fix a bug where inotify usage would parse the same event
124 multiple times, causing various forms of breakage.
125 - greatly reduce stack usage for inotify (8kb to <0.5kb).
126 - expose ev_depth and ev_verify via the XS API.
127 - implement ev_cleanup watchers.
128 - (libev) ev_embed_stop did not correctly stop the watcher.
129 - (libev) disable poll backend on AIX.
130 - (libev) rename EV_TIMEOUT to EV_TIMER.
131 - (libev) add section on accept() problems to the manpage.
132 - (libev) no child watchers on win32.
133 - make code more aliasing compliant, in case perl is ever
134 translated to C.
135 - document the EV::CHECK runtime unavailability.
136 - ported to minix 3.1.7.
137
1383.9 Thu Dec 31 07:59:59 CET 2009
139 - disable t/07* under automatic testing.
140 - increase t/09* timeouts as netbsd has *horribly* broken
141 select/kevent that *usually* sleep >>0.6s instead of 0.3.
142 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
143 EV::BACKEND_ALL.
144 - (libev) signalfd is no longer used by default.
145 - (libev) backport inotify code to C89.
146 - (libev) inotify file descriptors could leak into child processes.
147 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
148 - (libev) take advantage of inotify_init1, if available.
149 - (libev) the signal handling pipe wasn't always initialised under windows.
150 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
151 - (libev) only replace ev_stat.prev when we detect an actual difference.
152
1533.8 Sun Aug 9 15:30:10 CEST 2009
154 - implement $loop->signal/signal_ns.
155 - (libev) incompatible change: do not necessarily reset signal
156 handler to SIG_DFL when a sighandler is stopped.
157 - (libev) ev_default_destroy did not properly free or zero some
158 members, potentially causing crashes and memory corruption on
159 repated ev_default_destroy/ev_default_loop calls.
160 - (libev) take advantage of signalfd on GNU/Linux systems.
161 - (libev) document that the signal mask might be in an unspecified
162 state when using libev's signal handling.
163 - (libev) take advantage of some GNU/Linux calls to set
164 cloexec/nonblock on fd creation, to avoid race conditions.
165 - implement internal glue code to interface more efficiently
166 with AnyEvent.
167
1683.7 Fri Jul 17 16:49:16 CEST 2009
169 - add EV::loop_verify and EV::loop_depth.
170 - use output filehandle for i/o watchers waiting
171 for EV_WRITE, otherwise input filehandle.
172 - use common schmorp.h header.
173 - add EV::Timer->remaining.
174 - allow for subclassing of EV::Loop (see the exciting
175 EV::Loop::Async module for an example).
176 - added EV::invoke_pending and EV::pending_count.
177
178 - (libev) ev_unloop and ev_loop wrongly used a global variable to
179 exit loops, instead of using a per-loop variable.
180 - (libev) the ev_set_io_collect_interval interpretation has changed.
181 - add new functionality: EV::invoke_pending, EV::pending_count.
182 - add $timer->remaining.
183 - add EV::loop_depth.
184 - (libev) calling unloop in fork/prepare watchers will no longer poll
185 for new events.
186 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
187 for slightly higher accuracy.
188 - (libev) actually 0-initialise struct sigaction when installing
189 signals.
190
1913.6 Tue Apr 28 02:50:37 CEST 2009
192 - keepalive(0) could decrease the refcount of the loop
193 permanently.
194 - add ev_suspend/ev_resume, also make ev_now_update
195 accessible via the XS API.
196 - most EV::<eventtype> constants were missing and have been
197 added :/.
198 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
199 - (libev) multiple timers becoming ready within an event loop
200 iteration will be invoked in the "correct" order now.
201 - (libev) do not leave the event loop early just because we have
202 no active watchers, fixing a problem when embedding a kqueue
203 loop that has active kernel events but no registered watchers
204 (reported by blacksand blacksand).
205 - (libev) correctly zero the idx values for arrays, so destroying
206 and reinitialising the default loop actually works (patch by
207 Malek Hadj-Ali).
208 - (libev) new EV::CUSTOM revents flag for use by applications.
209 - (libev) add documentation section about priorites.
210 - (libev) add a glossary to the dcoumentation.
211 - (libev) extend the ev_fork description slightly.
212 - (libev) optimize a jump out of call_pending.
213 - t/03_keepalive could fail when there was no actual error.
214
2153.53 Sun Feb 15 02:38:20 CET 2009
216 - (libev) on win32, the event loop creation could randomly fail
217 due to an initialised variable having the wrong value.
218 - (libev) probe for CLOCK_REALTIME support at runtime as well and
219 fall back to gettimeofday if there is an error, to support older
220 operating systems with newer header files/libraries.
221 - prefer gettimeofday over clock_gettime by default.
222
2233.52 Wed Jan 7 21:46:14 CET 2009
224 - (libev) fix some issues in the select backend when in fd_set mode.
225 - (libev) due to a thinko, instead of disabling everything but
226 select on the borked OS X platform, everything but select was
227 allowed (reported by Emanuele Giaquinta).
228 - (libev) actually verify that local and remote port are matching in
229 libev's socketpair emulation, which makes denial-of-service
230 attacks harder (but not impossible - it's windows). Make sure
231 it even works under vista, which thinks that getpeer/sockname
232 should return fantasy port numbers.
233
2343.51 Wed Dec 24 23:01:59 CET 2008
235 - do not cache the arguments passed to callbacks if the refcount
236 indicates that the callback has stolen them.
237 - (libev) try to avoid librt on GNU/Linux.
238 - (libev) check port_getn return value dfferently, might potentially
239 avoid problems.
240 - (libev) fix a bug with stat watchers possibly causing freezes.
241 - (libev) work around OS X 10.5 breaking poll, now select is the
242 only viable choice left on that pile of garbage.
243 - play tester whore: disable some tests that typically fail only
244 on cpan tester machines.
245
2463.49 Wed Nov 19 11:26:53 CET 2008
247 - fix typos in manpage (Alex Efros).
248 - increase timing even further, for the ever-overloaded cpan-tester
249 machines, and to the detriment of everybody else who wants a fast
250 make test.
251 - possible 5.6 compatibility.
252 - (libev) use inotify even on buggy kernels, but don't rely on it.
253 - (libev) use inotify only as an added hint on network filesystems.
254
2553.48 Thu Oct 30 09:09:48 CET 2008
256 - (libev) use a generation counter to detect spurious epoll events
257 and recreate the kernel in such a case (sorry, it's slow, but
258 I didn't design epoll...).
259 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
260 backend in some cases.
261 - (libev) use memset to initialise most arrays now and do away
262 with the init functions.
263 - speed up event callback invocation further (~15%), by
264 not creating the object reference each time.
265 - EV::sleep was documented, but not implemented. fun.
266
2673.45 Tue Oct 21 22:20:39 CEST 2008
268 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
269 - (libev) ev_embed will now automatically follow fork.
270 - (libev) ev_once will now pass both io and timeout events to
271 the callback when both happen concurrently, instead of giving
272 one precedence.
273 - install C library documentation as EV::libev manpage (sorry, oesi).
274 - (libev) fix a minor performance bug in ev_stat handling.
275
2763.44 Mon Sep 29 05:16:31 CEST 2008
277 - (libev) add EV::now_update and $loop->now_update.
278
2793.431 Sun Jul 13 00:19:02 CEST 2008
280 - made the EV::embed callback optional again. reported by
281 Vladimir Timofeev.
282
2833.43 Tue Jul 8 20:56:31 CEST 2008
284 - disabled warnings in EV.pm, the CHECK issue is now understood
285 and harmless.
286
2873.42 Mon May 26 07:36:46 CEST 2008
288 - (libev) work around another bug in windows perls and
289 windows itself: failed connects do NOT set read or write
290 flags in select, but this version of libev will.
291
2923.41 Thu May 22 01:39:40 CEST 2008
293 - (libev) fix many heap-related bugs (timers, periodics).
294 - (libev) improve timing stability of timers and periodics.
295 - expose ev_loop_verify to perl code.
296 - clarify documentation for periodic reschedule callbacks.
297 - verify that the passed callback argument is indeed a code
298 reference, for earlier error reporting and a nice calling
299 speed increase (as well as saving memory).
300
3013.4 Tue May 20 21:51:55 CEST 2008
302 - (libev) work around both a windows bug and a bug in perl's
303 select on windows when not waiting for any file descriptors.
304 - bundle ev.pod into the tarball, just to increase its size
305 (and for the poor internetless person).
306
3073.33 Sun May 18 12:43:04 CEST 2008
308 - (libev) use numerous enhancements such as a more
309 cache-friendly 4-heap and heap index caching for timers.
310 - remove undocumented ev_timer->at accessor.

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

3353.0 Mon Jan 28 13:23:11 CET 2008
336 - upgrade to libev-3.0.
337 - change child handler to incorporate tracing flag.
338
3392.01 Mon Dec 31 01:59:19 CET 2007
340 - found a minor problem in the testsuite that is only
341 caught by new Test::Harness versions (reported by Andreas
342 König).
343
3442.0 Sat Dec 22 17:47:03 CET 2007
345 - no longer force kqueue when enabled, enable it
