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

225 Vladimir Timofeev.
226
227 3.43 Tue Jul 8 20:56:31 CEST 2008

230
231 3.42 Mon May 26 07:36:46 CEST 2008
232 - (libev) work around another bug in windows perls and
233 windows itself: failed connects do NOT set read or write

235
236 3.41 Thu May 22 01:39:40 CEST 2008

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