1 Revision history for Perl extension EV
2
3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 - try to name ev.h more explicitly, to hopefully improve portability.
7 - opportunistically round up wait times for poll and epoll backend,
8 to avoid unnecessary loop iterations.
9 - add build dependency on ev_linuxaio.c.
10 - quickly (re)-ported to minix 3.3 before minix crashed again.
11
12 4.27 Thu Jun 27 09:39:58 CEST 2019
13 - (libev) completely rewritten linuxaio backend, maybe
14 usable as a general-use backend.
15 - (libev) use more aggressive assertions to catch
16 more usage errors.
17 - allow users to re-enable assert() in case it is disabled
18 by perl (which is typically the case).
19
20 4.26 Mon Jun 24 23:39:40 CEST 2019
21 - (libev) included experimental linux aio backend.
22 - allow the linux aio backend to be used by default
23 only when explicitly configured during Makefile.PL time.
24
25 4.25 Fri Dec 21 08:04:26 CET 2018
26 - (libev) updated to libev 4.25, minor fixes and enhancements.
27 - document the requirement to "use EV" when using EV::MakeMaker.
28 - only use __register_atfork with glibc and uclibc, as musl
29 defines __linux__, but doesn't implement the linux standard
30 base ABI, nor makes itself detectable via a macro, both apparently
31 by design, winning the "broken by design 2016 award" - well done.
32 - correct EV::periodic example 24h after midnight -> one day after
33 midnight (reported by Felix Ostmann).
34
35 4.22 Sun Dec 20 02:34:39 CET 2015
36 - (libev) when epoll detects unremovable fds in the fd set, rebuild
37 only the epoll descriptor, not the signal pipe, to avoid
38 SIGPIPE in ev_async_send. This doesn't solve it on fork,
39 so document what needs to be done in ev_loop_fork
40 (analyzed by Benjamin Mahler).
41 - (libev) remove superfluous sys/timeb.h include on win32
42 (analyzed by Jason Madden).
43 - updated libecb.
44
45 4.21 Mon Jul 13 21:47:33 CEST 2015
46 - allow argument in timer->again.
47 - document timer->remaining.
48 - document default repeat value for timer->set.
49
50 4.20 Sat Jun 20 13:07:34 CEST 2015
51 - added stability canary support.
52 - truly rely on automatic configuration for clock_gettime and others.
53 unfortunately, this doesn't help with activeperl and similar perls,
54 which define _POSIX_TIMERS without actually implementing any of it.
55 - (libev, ecb) make it compile as C++ again.
56 - (libev) fix a potential aliasing issue when accessing watcher cbs.
57
58 4.18 Sat Sep 6 20:37:23 CEST 2014
59 - use slightly better weay to find includes, to support multiarch
60 on newer perls.
61
62 4.17 Fri Apr 11 06:22:38 CEST 2014
63 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
64 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
65 in 5.18. What's so attractive about giving a shit about backwards
66 compatibility - I will never understand.
67
68 4.16 Sat Mar 8 16:49:05 CET 2014
69 - make sure EV::CHECK is available at all times.
70 - avoid a spurious warning when perl -w overrides "no warnings".
71 - use perl's signal implementation on WIN32.
72 - ensure extern "C" function pointers are used for externally-visible
73 pointers.
74 - (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
75 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
76 - (libev) in the absence of autoconf, do not use the clock syscall
77 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
78 doing clock_gettime in userspace).
79 - (ecb) work around memory barriers and volatile apparently both being
80 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
81
82 4.15 Fri Mar 1 12:15:53 CET 2013
83 - (libev) upgrade to 4.15 - too many changes to list.
84 - EV::run now returns a boolean.
85 - API version 5:1.
86 - document that cleanup watchers are not available via perl.
87 - cast I32 to int in error message printf.
88 - remove dependencies on librt and libpthreads on GNU/Linux.
89
90 4.11 Sat Feb 4 19:56:26 CET 2012
91 - (libev) implement memory fences for (obsolete) llvm-gcc.
92
93 4.10 Thu Jan 19 18:54:23 CET 2012
94 - (libev) fix a race where the workaround against the epoll fork
95 bugs caused signals to not be handled anymore.
96 - (libev) correct backend_fudge for most backends, and implement
97 a windows specific workaround to avoid looping because we call
98 both select and Sleep, both with different time resolutions.
99 - e_new wasn't declared static (causing very minor .so bloat).
100 - replace more old api names by new ones.
101
102 4.03 Tue Jan 11 14:51:05 CET 2011
103 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
104 links against -lpthread anyways - as a result, EV might now take
105 advantage of fast userspace clock_gettime implementations,
106 but also links against -lrt.
107 - (libev) lots of event port bug workarounds.
108 - (libev) officially support files in I/O watchers.
109 - (libev) new function ev_feed_signal.
110 - fix documentation parts still refering to the 3.x API.
111
112 4.02 Thu Dec 30 08:27:41 CET 2010
113 - the revents argument did not stringify correctly, as only the
114 numeric value was updated, while the string value was kept from
115 previous invocations.
116
117 4.01 Sun Dec 5 12:42:13 CET 2010
118 - fully support EV_COMPAT3=0.
119 - default_fork was stupidly defined as inline.
120 - ask cpan to upgrade AnyEvent if < 5.29.
121 - support EV_EXTRA_DEFS during configuration.
122 - support -DEV_NO_LOOPS for snakker build.
123
124 4.00 Mon Oct 25 13:30:09 CEST 2010
125 - many API changes, see the manual.
126 - (libev) lots and lots of bugfixes, see the ev documentation.
127 - fix a bug where inotify usage would parse the same event
128 multiple times, causing various forms of breakage.
129 - greatly reduce stack usage for inotify (8kb to <0.5kb).
130 - expose ev_depth and ev_verify via the XS API.
131 - implement ev_cleanup watchers.
132 - (libev) ev_embed_stop did not correctly stop the watcher.
133 - (libev) disable poll backend on AIX.
134 - (libev) rename EV_TIMEOUT to EV_TIMER.
135 - (libev) add section on accept() problems to the manpage.
136 - (libev) no child watchers on win32.
137 - make code more aliasing compliant, in case perl is ever
138 translated to C.
139 - document the EV::CHECK runtime unavailability.
140 - ported to minix 3.1.7.
141
142 3.9 Thu Dec 31 07:59:59 CET 2009
143 - disable t/07* under automatic testing.
144 - increase t/09* timeouts as netbsd has *horribly* broken
145 select/kevent that *usually* sleep >>0.6s instead of 0.3.
146 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
147 EV::BACKEND_ALL.
148 - (libev) signalfd is no longer used by default.
149 - (libev) backport inotify code to C89.
150 - (libev) inotify file descriptors could leak into child processes.
151 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
152 - (libev) take advantage of inotify_init1, if available.
153 - (libev) the signal handling pipe wasn't always initialised under windows.
154 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
155 - (libev) only replace ev_stat.prev when we detect an actual difference.
156
157 3.8 Sun Aug 9 15:30:10 CEST 2009
158 - implement $loop->signal/signal_ns.
159 - (libev) incompatible change: do not necessarily reset signal
160 handler to SIG_DFL when a sighandler is stopped.
161 - (libev) ev_default_destroy did not properly free or zero some
162 members, potentially causing crashes and memory corruption on
163 repated ev_default_destroy/ev_default_loop calls.
164 - (libev) take advantage of signalfd on GNU/Linux systems.
165 - (libev) document that the signal mask might be in an unspecified
166 state when using libev's signal handling.
167 - (libev) take advantage of some GNU/Linux calls to set
168 cloexec/nonblock on fd creation, to avoid race conditions.
169 - implement internal glue code to interface more efficiently
170 with AnyEvent.
171
172 3.7 Fri Jul 17 16:49:16 CEST 2009
173 - add EV::loop_verify and EV::loop_depth.
174 - use output filehandle for i/o watchers waiting
175 for EV_WRITE, otherwise input filehandle.
176 - use common schmorp.h header.
177 - add EV::Timer->remaining.
178 - allow for subclassing of EV::Loop (see the exciting
179 EV::Loop::Async module for an example).
180 - added EV::invoke_pending and EV::pending_count.
181
182 - (libev) ev_unloop and ev_loop wrongly used a global variable to
183 exit loops, instead of using a per-loop variable.
184 - (libev) the ev_set_io_collect_interval interpretation has changed.
185 - add new functionality: EV::invoke_pending, EV::pending_count.
186 - add $timer->remaining.
187 - add EV::loop_depth.
188 - (libev) calling unloop in fork/prepare watchers will no longer poll
189 for new events.
190 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
191 for slightly higher accuracy.
192 - (libev) actually 0-initialise struct sigaction when installing
193 signals.
194
195 3.6 Tue Apr 28 02:50:37 CEST 2009
196 - keepalive(0) could decrease the refcount of the loop
197 permanently.
198 - add ev_suspend/ev_resume, also make ev_now_update
199 accessible via the XS API.
200 - most EV::<eventtype> constants were missing and have been
201 added :/.
202 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
203 - (libev) multiple timers becoming ready within an event loop
204 iteration will be invoked in the "correct" order now.
205 - (libev) do not leave the event loop early just because we have
206 no active watchers, fixing a problem when embedding a kqueue
207 loop that has active kernel events but no registered watchers
208 (reported by blacksand blacksand).
209 - (libev) correctly zero the idx values for arrays, so destroying
210 and reinitialising the default loop actually works (patch by
211 Malek Hadj-Ali).
212 - (libev) new EV::CUSTOM revents flag for use by applications.
213 - (libev) add documentation section about priorites.
214 - (libev) add a glossary to the dcoumentation.
215 - (libev) extend the ev_fork description slightly.
216 - (libev) optimize a jump out of call_pending.
217 - t/03_keepalive could fail when there was no actual error.
218
219 3.53 Sun Feb 15 02:38:20 CET 2009
220 - (libev) on win32, the event loop creation could randomly fail
221 due to an initialised variable having the wrong value.
222 - (libev) probe for CLOCK_REALTIME support at runtime as well and
223 fall back to gettimeofday if there is an error, to support older
224 operating systems with newer header files/libraries.
225 - prefer gettimeofday over clock_gettime by default.
226
227 3.52 Wed Jan 7 21:46:14 CET 2009
228 - (libev) fix some issues in the select backend when in fd_set mode.
229 - (libev) due to a thinko, instead of disabling everything but
230 select on the borked OS X platform, everything but select was
231 allowed (reported by Emanuele Giaquinta).
232 - (libev) actually verify that local and remote port are matching in
233 libev's socketpair emulation, which makes denial-of-service
234 attacks harder (but not impossible - it's windows). Make sure
235 it even works under vista, which thinks that getpeer/sockname
236 should return fantasy port numbers.
237
238 3.51 Wed Dec 24 23:01:59 CET 2008
239 - do not cache the arguments passed to callbacks if the refcount
240 indicates that the callback has stolen them.
241 - (libev) try to avoid librt on GNU/Linux.
242 - (libev) check port_getn return value dfferently, might potentially
243 avoid problems.
244 - (libev) fix a bug with stat watchers possibly causing freezes.
245 - (libev) work around OS X 10.5 breaking poll, now select is the
246 only viable choice left on that pile of garbage.
247 - play tester whore: disable some tests that typically fail only
248 on cpan tester machines.
249
250 3.49 Wed Nov 19 11:26:53 CET 2008
251 - fix typos in manpage (Alex Efros).
252 - increase timing even further, for the ever-overloaded cpan-tester
253 machines, and to the detriment of everybody else who wants a fast
254 make test.
255 - possible 5.6 compatibility.
256 - (libev) use inotify even on buggy kernels, but don't rely on it.
257 - (libev) use inotify only as an added hint on network filesystems.
258
259 3.48 Thu Oct 30 09:09:48 CET 2008
260 - (libev) use a generation counter to detect spurious epoll events
261 and recreate the kernel in such a case (sorry, it's slow, but
262 I didn't design epoll...).
263 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
264 backend in some cases.
265 - (libev) use memset to initialise most arrays now and do away
266 with the init functions.
267 - speed up event callback invocation further (~15%), by
268 not creating the object reference each time.
269 - EV::sleep was documented, but not implemented. fun.
270
271 3.45 Tue Oct 21 22:20:39 CEST 2008
272 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
273 - (libev) ev_embed will now automatically follow fork.
274 - (libev) ev_once will now pass both io and timeout events to
275 the callback when both happen concurrently, instead of giving
276 one precedence.
277 - install C library documentation as EV::libev manpage (sorry, oesi).
278 - (libev) fix a minor performance bug in ev_stat handling.
279
280 3.44 Mon Sep 29 05:16:31 CEST 2008
281 - (libev) add EV::now_update and $loop->now_update.
282
283 3.431 Sun Jul 13 00:19:02 CEST 2008
284 - made the EV::embed callback optional again. reported by
285 Vladimir Timofeev.
286
287 3.43 Tue Jul 8 20:56:31 CEST 2008
288 - disabled warnings in EV.pm, the CHECK issue is now understood
289 and harmless.
290
291 3.42 Mon May 26 07:36:46 CEST 2008
292 - (libev) work around another bug in windows perls and
293 windows itself: failed connects do NOT set read or write
294 flags in select, but this version of libev will.
295
296 3.41 Thu May 22 01:39:40 CEST 2008
297 - (libev) fix many heap-related bugs (timers, periodics).
298 - (libev) improve timing stability of timers and periodics.
299 - expose ev_loop_verify to perl code.
300 - clarify documentation for periodic reschedule callbacks.
301 - verify that the passed callback argument is indeed a code
302 reference, for earlier error reporting and a nice calling
303 speed increase (as well as saving memory).
304
305 3.4 Tue May 20 21:51:55 CEST 2008
306 - (libev) work around both a windows bug and a bug in perl's
307 select on windows when not waiting for any file descriptors.
308 - bundle ev.pod into the tarball, just to increase its size
309 (and for the poor internetless person).
310
311 3.33 Sun May 18 12:43:04 CEST 2008
312 - (libev) use numerous enhancements such as a more
313 cache-friendly 4-heap and heap index caching for timers.

333
334 3.1 Sat Mar 8 11:41:14 CET 2008
335 - add ev_sync_* and ev_fork_* to EVAPI.h.
336 - provide EV::Embed->sweep method.

339 3.0 Mon Jan 28 13:23:11 CET 2008
340 - upgrade to libev-3.0.
341 - change child handler to incorporate tracing flag.
342
343 2.01 Mon Dec 31 01:59:19 CET 2007
344 - found a minor problem in the testsuite that is only
345 caught by new Test::Harness versions (reported by Andreas
346 König).
347
348 2.0 Sat Dec 22 17:47:03 CET 2007

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

428 1.2 Thu Nov 22 05:44:09 CET 2007
429 - disable kqueue by default on !netbsd, as its broken on freebsd,
430 darwin and openbsd and thus almost everywhere.
431 - add some allowance in t/01_timer.t for the uneven monotonic
432 vs. realtime clock tick on at least freebsd.
