27TODO: canary
28 - document the requirement to "use EV" when using EV::MakeMaker.
29 - only use __register_atfork with glibc and uclibc, as musl
30 defines __linux__, but doesn't implement the linux standard
31 base ABI, nor makes itself detectable via a macro, both apparently
32 by design, winning the "broken by design 2016 award" - well done.
33 - correct EV::periodic example 24h after midnight -> one day after
34 midnight (reported by Felix Ostmann).
35
364.22 Sun Dec 20 02:34:39 CET 2015
37 - (libev) when epoll detects unremovable fds in the fd set, rebuild
38 only the epoll descriptor, not the signal pipe, to avoid
39 SIGPIPE in ev_async_send. This doesn't solve it on fork,
40 so document what needs to be done in ev_loop_fork
41 (analyzed by Benjamin Mahler).
42 - (libev) remove superfluous sys/timeb.h include on win32
43 (analyzed by Jason Madden).
44 - updated libecb.
45
464.21 Mon Jul 13 21:47:33 CEST 2015
47 - allow argument in timer->again.
48 - document timer->remaining.
49 - document default repeat value for timer->set.
50
514.20 Sat Jun 20 13:07:34 CEST 2015
52 - added stability canary support.
53 - truly rely on automatic configuration for clock_gettime and others.
54 unfortunately, this doesn't help with activeperl and similar perls,
55 which define _POSIX_TIMERS without actually implementing any of it.
56 - (libev, ecb) make it compile as C++ again.
57 - (libev) fix a potential aliasing issue when accessing watcher cbs.
58
594.18 Sat Sep 6 20:37:23 CEST 2014
60 - use slightly better weay to find includes, to support multiarch
61 on newer perls.
62
634.17 Fri Apr 11 06:22:38 CEST 2014
64 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
65 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
66 in 5.18. What's so attractive about giving a shit about backwards
67 compatibility - I will never understand.
68
694.16 Sat Mar 8 16:49:05 CET 2014
70 - make sure EV::CHECK is available at all times.
71 - avoid a spurious warning when perl -w overrides "no warnings".
72 - use perl's signal implementation on WIN32.
73 - ensure extern "C" function pointers are used for externally-visible
74 pointers.
75 - (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
76 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
77 - (libev) in the absence of autoconf, do not use the clock syscall
78 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
79 doing clock_gettime in userspace).
80 - (ecb) work around memory barriers and volatile apparently both being
81 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
82
834.15 Fri Mar 1 12:15:53 CET 2013
84 - (libev) upgrade to 4.15 - too many changes to list.
85 - EV::run now returns a boolean.
86 - API version 5:1.
87 - document that cleanup watchers are not available via perl.
88 - cast I32 to int in error message printf.
89 - remove dependencies on librt and libpthreads on GNU/Linux.
90
914.11 Sat Feb 4 19:56:26 CET 2012
92 - (libev) implement memory fences for (obsolete) llvm-gcc.
93
944.10 Thu Jan 19 18:54:23 CET 2012
95 - (libev) fix a race where the workaround against the epoll fork
96 bugs caused signals to not be handled anymore.
97 - (libev) correct backend_fudge for most backends, and implement
98 a windows specific workaround to avoid looping because we call
99 both select and Sleep, both with different time resolutions.
100 - e_new wasn't declared static (causing very minor .so bloat).
101 - replace more old api names by new ones.
102
1034.03 Tue Jan 11 14:51:05 CET 2011
104 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
105 links against -lpthread anyways - as a result, EV might now take
106 advantage of fast userspace clock_gettime implementations,
107 but also links against -lrt.
108 - (libev) lots of event port bug workarounds.
109 - (libev) officially support files in I/O watchers.
110 - (libev) new function ev_feed_signal.
111 - fix documentation parts still refering to the 3.x API.
112
1134.02 Thu Dec 30 08:27:41 CET 2010
114 - the revents argument did not stringify correctly, as only the
115 numeric value was updated, while the string value was kept from
116 previous invocations.
117
1184.01 Sun Dec 5 12:42:13 CET 2010
119 - fully support EV_COMPAT3=0.
120 - default_fork was stupidly defined as inline.
121 - ask cpan to upgrade AnyEvent if < 5.29.
122 - support EV_EXTRA_DEFS during configuration.
123 - support -DEV_NO_LOOPS for snakker build.
124
1254.00 Mon Oct 25 13:30:09 CEST 2010
126 - many API changes, see the manual.
127 - (libev) lots and lots of bugfixes, see the ev documentation.
128 - fix a bug where inotify usage would parse the same event
129 multiple times, causing various forms of breakage.
130 - greatly reduce stack usage for inotify (8kb to <0.5kb).
131 - expose ev_depth and ev_verify via the XS API.
132 - implement ev_cleanup watchers.
133 - (libev) ev_embed_stop did not correctly stop the watcher.
134 - (libev) disable poll backend on AIX.
135 - (libev) rename EV_TIMEOUT to EV_TIMER.
136 - (libev) add section on accept() problems to the manpage.
137 - (libev) no child watchers on win32.
138 - make code more aliasing compliant, in case perl is ever
139 translated to C.
140 - document the EV::CHECK runtime unavailability.
141 - ported to minix 3.1.7.
142
1433.9 Thu Dec 31 07:59:59 CET 2009
144 - disable t/07* under automatic testing.
145 - increase t/09* timeouts as netbsd has *horribly* broken
146 select/kevent that *usually* sleep >>0.6s instead of 0.3.
147 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
148 EV::BACKEND_ALL.
149 - (libev) signalfd is no longer used by default.
150 - (libev) backport inotify code to C89.
151 - (libev) inotify file descriptors could leak into child processes.
152 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
153 - (libev) take advantage of inotify_init1, if available.
154 - (libev) the signal handling pipe wasn't always initialised under windows.
155 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
156 - (libev) only replace ev_stat.prev when we detect an actual difference.
157
1583.8 Sun Aug 9 15:30:10 CEST 2009
159 - implement $loop->signal/signal_ns.
160 - (libev) incompatible change: do not necessarily reset signal
161 handler to SIG_DFL when a sighandler is stopped.
162 - (libev) ev_default_destroy did not properly free or zero some
163 members, potentially causing crashes and memory corruption on
164 repated ev_default_destroy/ev_default_loop calls.
165 - (libev) take advantage of signalfd on GNU/Linux systems.
166 - (libev) document that the signal mask might be in an unspecified
167 state when using libev's signal handling.
168 - (libev) take advantage of some GNU/Linux calls to set
169 cloexec/nonblock on fd creation, to avoid race conditions.
170 - implement internal glue code to interface more efficiently
171 with AnyEvent.
172
1733.7 Fri Jul 17 16:49:16 CEST 2009
174 - add EV::loop_verify and EV::loop_depth.
175 - use output filehandle for i/o watchers waiting
176 for EV_WRITE, otherwise input filehandle.
177 - use common schmorp.h header.
178 - add EV::Timer->remaining.
179 - allow for subclassing of EV::Loop (see the exciting
180 EV::Loop::Async module for an example).
181 - added EV::invoke_pending and EV::pending_count.
182
183 - (libev) ev_unloop and ev_loop wrongly used a global variable to
184 exit loops, instead of using a per-loop variable.
185 - (libev) the ev_set_io_collect_interval interpretation has changed.
186 - add new functionality: EV::invoke_pending, EV::pending_count.
187 - add $timer->remaining.
188 - add EV::loop_depth.
189 - (libev) calling unloop in fork/prepare watchers will no longer poll
190 for new events.
191 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
192 for slightly higher accuracy.
193 - (libev) actually 0-initialise struct sigaction when installing
194 signals.
195
1963.6 Tue Apr 28 02:50:37 CEST 2009
197 - keepalive(0) could decrease the refcount of the loop
198 permanently.
199 - add ev_suspend/ev_resume, also make ev_now_update
200 accessible via the XS API.
201 - most EV::<eventtype> constants were missing and have been
202 added :/.
203 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
204 - (libev) multiple timers becoming ready within an event loop
205 iteration will be invoked in the "correct" order now.
206 - (libev) do not leave the event loop early just because we have
207 no active watchers, fixing a problem when embedding a kqueue
208 loop that has active kernel events but no registered watchers
209 (reported by blacksand blacksand).
210 - (libev) correctly zero the idx values for arrays, so destroying
211 and reinitialising the default loop actually works (patch by
212 Malek Hadj-Ali).
213 - (libev) new EV::CUSTOM revents flag for use by applications.
214 - (libev) add documentation section about priorites.
215 - (libev) add a glossary to the dcoumentation.
216 - (libev) extend the ev_fork description slightly.
217 - (libev) optimize a jump out of call_pending.
218 - t/03_keepalive could fail when there was no actual error.
219
2203.53 Sun Feb 15 02:38:20 CET 2009
221 - (libev) on win32, the event loop creation could randomly fail
222 due to an initialised variable having the wrong value.
223 - (libev) probe for CLOCK_REALTIME support at runtime as well and
224 fall back to gettimeofday if there is an error, to support older
225 operating systems with newer header files/libraries.
226 - prefer gettimeofday over clock_gettime by default.
227
2283.52 Wed Jan 7 21:46:14 CET 2009
229 - (libev) fix some issues in the select backend when in fd_set mode.
230 - (libev) due to a thinko, instead of disabling everything but
231 select on the borked OS X platform, everything but select was
232 allowed (reported by Emanuele Giaquinta).
233 - (libev) actually verify that local and remote port are matching in
234 libev's socketpair emulation, which makes denial-of-service
235 attacks harder (but not impossible - it's windows). Make sure
236 it even works under vista, which thinks that getpeer/sockname
237 should return fantasy port numbers.
238
2393.51 Wed Dec 24 23:01:59 CET 2008
240 - do not cache the arguments passed to callbacks if the refcount
241 indicates that the callback has stolen them.
242 - (libev) try to avoid librt on GNU/Linux.
243 - (libev) check port_getn return value dfferently, might potentially
244 avoid problems.
245 - (libev) fix a bug with stat watchers possibly causing freezes.
246 - (libev) work around OS X 10.5 breaking poll, now select is the
247 only viable choice left on that pile of garbage.
248 - play tester whore: disable some tests that typically fail only
249 on cpan tester machines.
250
2513.49 Wed Nov 19 11:26:53 CET 2008
252 - fix typos in manpage (Alex Efros).
253 - increase timing even further, for the ever-overloaded cpan-tester
254 machines, and to the detriment of everybody else who wants a fast
255 make test.
256 - possible 5.6 compatibility.
257 - (libev) use inotify even on buggy kernels, but don't rely on it.
258 - (libev) use inotify only as an added hint on network filesystems.
259
2603.48 Thu Oct 30 09:09:48 CET 2008
261 - (libev) use a generation counter to detect spurious epoll events
262 and recreate the kernel in such a case (sorry, it's slow, but
263 I didn't design epoll...).
264 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
265 backend in some cases.
266 - (libev) use memset to initialise most arrays now and do away
267 with the init functions.
268 - speed up event callback invocation further (~15%), by
269 not creating the object reference each time.
270 - EV::sleep was documented, but not implemented. fun.
271
2723.45 Tue Oct 21 22:20:39 CEST 2008
273 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
274 - (libev) ev_embed will now automatically follow fork.
275 - (libev) ev_once will now pass both io and timeout events to
276 the callback when both happen concurrently, instead of giving
277 one precedence.
278 - install C library documentation as EV::libev manpage (sorry, oesi).
279 - (libev) fix a minor performance bug in ev_stat handling.
280
2813.44 Mon Sep 29 05:16:31 CEST 2008
282 - (libev) add EV::now_update and $loop->now_update.
283
2843.431 Sun Jul 13 00:19:02 CEST 2008
285 - made the EV::embed callback optional again. reported by
286 Vladimir Timofeev.
287
2883.43 Tue Jul 8 20:56:31 CEST 2008
289 - disabled warnings in EV.pm, the CHECK issue is now understood
290 and harmless.
291
2923.42 Mon May 26 07:36:46 CEST 2008
293 - (libev) work around another bug in windows perls and
294 windows itself: failed connects do NOT set read or write
295 flags in select, but this version of libev will.
296
2973.41 Thu May 22 01:39:40 CEST 2008
298 - (libev) fix many heap-related bugs (timers, periodics).
299 - (libev) improve timing stability of timers and periodics.
300 - expose ev_loop_verify to perl code.
301 - clarify documentation for periodic reschedule callbacks.
302 - verify that the passed callback argument is indeed a code
303 reference, for earlier error reporting and a nice calling
304 speed increase (as well as saving memory).
305
3063.4 Tue May 20 21:51:55 CEST 2008
307 - (libev) work around both a windows bug and a bug in perl's
308 select on windows when not waiting for any file descriptors.
309 - bundle ev.pod into the tarball, just to increase its size
310 (and for the poor internetless person).
311
3123.33 Sun May 18 12:43:04 CEST 2008
313 - (libev) use numerous enhancements such as a more
314 cache-friendly 4-heap and heap index caching for timers.

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

3442.01 Mon Dec 31 01:59:19 CET 2007
345 - found a minor problem in the testsuite that is only
346 caught by new Test::Harness versions (reported by Andreas
347 König).
348
3492.0 Sat Dec 22 17:47:03 CET 2007
