3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 TODO: better multiarch detection
7
8 - make sure EV::CHECK is available at all times.
9 - avoid a spurious warning when perl -w overrides "no warnings".
10 - use perl's signal implementation on WIN32.
11
12 4.15 Fri Mar 1 12:15:53 CET 2013
13 - (libev) upgrade to 4.15 - too many changes to list.
14 - EV::run now returns a boolean.
15 - API version 5:1.
16 - document that cleanup watchers are not available via perl.
17 - cast I32 to int in error message printf.
18 - remove dependencies on librt and libpthreads on GNU/Linux.
19
20 4.11 Sat Feb 4 19:56:26 CET 2012
21 - (libev) implement memory fences for (obsolete) llvm-gcc.
22
23 4.10 Thu Jan 19 18:54:23 CET 2012
24 - (libev) fix a race where the workaround against the epoll fork
25 bugs caused signals to not be handled anymore.
26 - (libev) correct backend_fudge for most backends, and implement
27 a windows specific workaround to avoid looping because we call
28 both select and Sleep, both with different time resolutions.
29 - e_new wasn't declared static (causing very minor .so bloat).
30 - replace more old api names by new ones.
31
32 4.03 Tue Jan 11 14:51:05 CET 2011
33 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
34 links against -lpthread anyways - as a result, EV might now take
35 advantage of fast userspace clock_gettime implementations,
36 but also links against -lrt.
37 - (libev) lots of event port bug workarounds.
38 - (libev) officially support files in I/O watchers.
39 - (libev) new function ev_feed_signal.
40 - fix documentation parts still refering to the 3.x API.
41
42 4.02 Thu Dec 30 08:27:41 CET 2010
43 - the revents argument did not stringify correctly, as only the
44 numeric value was updated, while the string value was kept from
45 previous invocations.
46
47 4.01 Sun Dec 5 12:42:13 CET 2010
48 - fully support EV_COMPAT3=0.
49 - default_fork was stupidly defined as inline.
50 - ask cpan to upgrade AnyEvent if < 5.29.
51 - support EV_EXTRA_DEFS during configuration.
52 - support -DEV_NO_LOOPS for snakker build.
53
54 4.00 Mon Oct 25 13:30:09 CEST 2010
55 - many API changes, see the manual.
56 - (libev) lots and lots of bugfixes, see the ev documentation.
57 - fix a bug where inotify usage would parse the same event
58 multiple times, causing various forms of breakage.
59 - greatly reduce stack usage for inotify (8kb to <0.5kb).
60 - expose ev_depth and ev_verify via the XS API.
61 - implement ev_cleanup watchers.
62 - (libev) ev_embed_stop did not correctly stop the watcher.
63 - (libev) disable poll backend on AIX.
64 - (libev) rename EV_TIMEOUT to EV_TIMER.
65 - (libev) add section on accept() problems to the manpage.
66 - (libev) no child watchers on win32.
67 - make code more aliasing compliant, in case perl is ever
68 translated to C.

70 - ported to minix 3.1.7.
71
72 3.9 Thu Dec 31 07:59:59 CET 2009
73 - disable t/07* under automatic testing.
74 - increase t/09* timeouts as netbsd has *horribly* broken
75 select/kevent that *usually* sleep >>0.6s instead of 0.3.
76 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
77 EV::BACKEND_ALL.
78 - (libev) signalfd is no longer used by default.
79 - (libev) backport inotify code to C89.
80 - (libev) inotify file descriptors could leak into child processes.
81 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
82 - (libev) take advantage of inotify_init1, if available.
83 - (libev) the signal handling pipe wasn't always initialised under windows.
84 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
85 - (libev) only replace ev_stat.prev when we detect an actual difference.
86
87 3.8 Sun Aug 9 15:30:10 CEST 2009
88 - implement $loop->signal/signal_ns.
89 - (libev) incompatible change: do not necessarily reset signal
90 handler to SIG_DFL when a sighandler is stopped.
91 - (libev) ev_default_destroy did not properly free or zero some
92 members, potentially causing crashes and memory corruption on
93 repated ev_default_destroy/ev_default_loop calls.
94 - (libev) take advantage of signalfd on GNU/Linux systems.
95 - (libev) document that the signal mask might be in an unspecified
96 state when using libev's signal handling.
97 - (libev) take advantage of some GNU/Linux calls to set
98 cloexec/nonblock on fd creation, to avoid race conditions.
99 - implement internal glue code to interface more efficiently
100 with AnyEvent.
101
102 3.7 Fri Jul 17 16:49:16 CEST 2009
103 - add EV::loop_verify and EV::loop_depth.
104 - use output filehandle for i/o watchers waiting
105 for EV_WRITE, otherwise input filehandle.
106 - use common schmorp.h header.
107 - add EV::Timer->remaining.
108 - allow for subclassing of EV::Loop (see the exciting
109 EV::Loop::Async module for an example).
110 - added EV::invoke_pending and EV::pending_count.
111
112 - (libev) ev_unloop and ev_loop wrongly used a global variable to
113 exit loops, instead of using a per-loop variable.
114 - (libev) the ev_set_io_collect_interval interpretation has changed.
115 - add new functionality: EV::invoke_pending, EV::pending_count.
116 - add $timer->remaining.
117 - add EV::loop_depth.
118 - (libev) calling unloop in fork/prepare watchers will no longer poll
119 for new events.
120 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
121 for slightly higher accuracy.
122 - (libev) actually 0-initialise struct sigaction when installing
123 signals.
124
125 3.6 Tue Apr 28 02:50:37 CEST 2009
126 - keepalive(0) could decrease the refcount of the loop
127 permanently.
128 - add ev_suspend/ev_resume, also make ev_now_update
129 accessible via the XS API.
130 - most EV::<eventtype> constants were missing and have been
131 added :/.
132 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
133 - (libev) multiple timers becoming ready within an event loop
134 iteration will be invoked in the "correct" order now.
135 - (libev) do not leave the event loop early just because we have
136 no active watchers, fixing a problem when embedding a kqueue
137 loop that has active kernel events but no registered watchers
138 (reported by blacksand blacksand).
139 - (libev) correctly zero the idx values for arrays, so destroying
140 and reinitialising the default loop actually works (patch by
141 Malek Hadj-Ali).
142 - (libev) new EV::CUSTOM revents flag for use by applications.
143 - (libev) add documentation section about priorites.
144 - (libev) add a glossary to the dcoumentation.
145 - (libev) extend the ev_fork description slightly.
146 - (libev) optimize a jump out of call_pending.
147 - t/03_keepalive could fail when there was no actual error.
148
149 3.53 Sun Feb 15 02:38:20 CET 2009
150 - (libev) on win32, the event loop creation could randomly fail
151 due to an initialised variable having the wrong value.
152 - (libev) probe for CLOCK_REALTIME support at runtime as well and
153 fall back to gettimeofday if there is an error, to support older
154 operating systems with newer header files/libraries.
155 - prefer gettimeofday over clock_gettime by default.
156
157 3.52 Wed Jan 7 21:46:14 CET 2009
158 - (libev) fix some issues in the select backend when in fd_set mode.
159 - (libev) due to a thinko, instead of disabling everything but
160 select on the borked OS X platform, everything but select was
161 allowed (reported by Emanuele Giaquinta).
162 - (libev) actually verify that local and remote port are matching in
163 libev's socketpair emulation, which makes denial-of-service
164 attacks harder (but not impossible - it's windows). Make sure
165 it even works under vista, which thinks that getpeer/sockname
166 should return fantasy port numbers.
167
168 3.51 Wed Dec 24 23:01:59 CET 2008
169 - do not cache the arguments passed to callbacks if the refcount
170 indicates that the callback has stolen them.
171 - (libev) try to avoid librt on GNU/Linux.
172 - (libev) check port_getn return value dfferently, might potentially
173 avoid problems.
174 - (libev) fix a bug with stat watchers possibly causing freezes.
175 - (libev) work around OS X 10.5 breaking poll, now select is the
176 only viable choice left on that pile of garbage.
177 - play tester whore: disable some tests that typically fail only
178 on cpan tester machines.
179
180 3.49 Wed Nov 19 11:26:53 CET 2008
181 - fix typos in manpage (Alex Efros).
182 - increase timing even further, for the ever-overloaded cpan-tester
183 machines, and to the detriment of everybody else who wants a fast
184 make test.
185 - possible 5.6 compatibility.
186 - (libev) use inotify even on buggy kernels, but don't rely on it.
187 - (libev) use inotify only as an added hint on network filesystems.
188
189 3.48 Thu Oct 30 09:09:48 CET 2008
190 - (libev) use a generation counter to detect spurious epoll events
191 and recreate the kernel in such a case (sorry, it's slow, but
192 I didn't design epoll...).
193 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
194 backend in some cases.
195 - (libev) use memset to initialise most arrays now and do away
196 with the init functions.
197 - speed up event callback invocation further (~15%), by
198 not creating the object reference each time.
199 - EV::sleep was documented, but not implemented. fun.
200
201 3.45 Tue Oct 21 22:20:39 CEST 2008
202 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
203 - (libev) ev_embed will now automatically follow fork.
204 - (libev) ev_once will now pass both io and timeout events to
205 the callback when both happen concurrently, instead of giving
206 one precedence.
207 - install C library documentation as EV::libev manpage (sorry, oesi).
208 - (libev) fix a minor performance bug in ev_stat handling.
209
210 3.44 Mon Sep 29 05:16:31 CEST 2008
211 - (libev) add EV::now_update and $loop->now_update.
212
213 3.431 Sun Jul 13 00:19:02 CEST 2008

220
221 3.42 Mon May 26 07:36:46 CEST 2008
222 - (libev) work around another bug in windows perls and
223 windows itself: failed connects do NOT set read or write

235 3.4 Tue May 20 21:51:55 CEST 2008
236 - (libev) work around both a windows bug and a bug in perl's
237 select on windows when not waiting for any file descriptors.
238 - bundle ev.pod into the tarball, just to increase its size
239 (and for the poor internetless person).
240
241 3.33 Sun May 18 12:43:04 CEST 2008
