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

235
236 3.42 Mon May 26 07:36:46 CEST 2008
237 - (libev) work around another bug in windows perls and
238 windows itself: failed connects do NOT set read or write

240
241 3.41 Thu May 22 01:39:40 CEST 2008

244 - expose ev_loop_verify to perl code.
245 - clarify documentation for periodic reschedule callbacks.
246 - verify that the passed callback argument is indeed a code
247 reference, for earlier error reporting and a nice calling
248 speed increase (as well as saving memory).
249
250 3.4 Tue May 20 21:51:55 CEST 2008
251 - (libev) work around both a windows bug and a bug in perl's
252 select on windows when not waiting for any file descriptors.
253 - bundle ev.pod into the tarball, just to increase its size
254 (and for the poor internetless person).
255
256 3.33 Sun May 18 12:43:04 CEST 2008
257 - (libev) use numerous enhancements such as a more
258 cache-friendly 4-heap and heap index caching for timers.
