2
3 Changes marked with (libev) are changes in libev, and have more
4 documentation in the libev Changes file.
5
6 - make sure EV::CHECK is available at all times.
7 - avoid a spurious warning when perl -w overrides "no warnings".
8
9 4.15 Fri Mar 1 12:15:53 CET 2013
10 - (libev) upgrade to 4.15 - too many changes to list.
11 - EV::run now returns a boolean.
12 - API version 5:1.
13 - document that cleanup watchers are not available via perl.
14 - cast I32 to int in error message printf.
15 - remove dependencies on librt and libpthreads on GNU/Linux.
16
17 4.11 Sat Feb 4 19:56:26 CET 2012
18 - (libev) implement memory fences for (obsolete) llvm-gcc.
19
20 4.10 Thu Jan 19 18:54:23 CET 2012
21 - (libev) fix a race where the workaround against the epoll fork
22 bugs caused signals to not be handled anymore.
23 - (libev) correct backend_fudge for most backends, and implement
24 a windows specific workaround to avoid looping because we call
25 both select and Sleep, both with different time resolutions.
26 - e_new wasn't declared static (causing very minor .so bloat).
27 - replace more old api names by new ones.
28
29 4.03 Tue Jan 11 14:51:05 CET 2011
30 - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
31 links against -lpthread anyways - as a result, EV might now take
32 advantage of fast userspace clock_gettime implementations,
33 but also links against -lrt.
34 - (libev) lots of event port bug workarounds.
35 - (libev) officially support files in I/O watchers.
36 - (libev) new function ev_feed_signal.
37 - fix documentation parts still refering to the 3.x API.
38
39 4.02 Thu Dec 30 08:27:41 CET 2010
40 - the revents argument did not stringify correctly, as only the
41 numeric value was updated, while the string value was kept from
42 previous invocations.
43
44 4.01 Sun Dec 5 12:42:13 CET 2010
45 - fully support EV_COMPAT3=0.
46 - default_fork was stupidly defined as inline.
47 - ask cpan to upgrade AnyEvent if < 5.29.
48 - support EV_EXTRA_DEFS during configuration.
49 - support -DEV_NO_LOOPS for snakker build.
50
51 4.00 Mon Oct 25 13:30:09 CEST 2010
52 - many API changes, see the manual.
53 - (libev) lots and lots of bugfixes, see the ev documentation.
54 - fix a bug where inotify usage would parse the same event
55 multiple times, causing various forms of breakage.
56 - greatly reduce stack usage for inotify (8kb to <0.5kb).
57 - expose ev_depth and ev_verify via the XS API.
58 - implement ev_cleanup watchers.
59 - (libev) ev_embed_stop did not correctly stop the watcher.
60 - (libev) disable poll backend on AIX.
61 - (libev) rename EV_TIMEOUT to EV_TIMER.
62 - (libev) add section on accept() problems to the manpage.
63 - (libev) no child watchers on win32.
64 - make code more aliasing compliant, in case perl is ever
65 translated to C.
66 - document the EV::CHECK runtime unavailability.
67 - ported to minix 3.1.7.
68
69 3.9 Thu Dec 31 07:59:59 CET 2009
70 - disable t/07* under automatic testing.
71 - increase t/09* timeouts as netbsd has *horribly* broken
72 select/kevent that *usually* sleep >>0.6s instead of 0.3.
73 - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
74 EV::BACKEND_ALL.
75 - (libev) signalfd is no longer used by default.
76 - (libev) backport inotify code to C89.
77 - (libev) inotify file descriptors could leak into child processes.
78 - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
79 - (libev) take advantage of inotify_init1, if available.
80 - (libev) the signal handling pipe wasn't always initialised under windows.
81 - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
82 - (libev) only replace ev_stat.prev when we detect an actual difference.
83
84 3.8 Sun Aug 9 15:30:10 CEST 2009
85 - implement $loop->signal/signal_ns.
86 - (libev) incompatible change: do not necessarily reset signal
87 handler to SIG_DFL when a sighandler is stopped.
88 - (libev) ev_default_destroy did not properly free or zero some
89 members, potentially causing crashes and memory corruption on
90 repated ev_default_destroy/ev_default_loop calls.
91 - (libev) take advantage of signalfd on GNU/Linux systems.
92 - (libev) document that the signal mask might be in an unspecified
93 state when using libev's signal handling.
94 - (libev) take advantage of some GNU/Linux calls to set
95 cloexec/nonblock on fd creation, to avoid race conditions.
96 - implement internal glue code to interface more efficiently
97 with AnyEvent.
98
99 3.7 Fri Jul 17 16:49:16 CEST 2009
100 - add EV::loop_verify and EV::loop_depth.
101 - use output filehandle for i/o watchers waiting
102 for EV_WRITE, otherwise input filehandle.
103 - use common schmorp.h header.
104 - add EV::Timer->remaining.
105 - allow for subclassing of EV::Loop (see the exciting
106 EV::Loop::Async module for an example).
107 - added EV::invoke_pending and EV::pending_count.
108
109 - (libev) ev_unloop and ev_loop wrongly used a global variable to
110 exit loops, instead of using a per-loop variable.
111 - (libev) the ev_set_io_collect_interval interpretation has changed.
112 - add new functionality: EV::invoke_pending, EV::pending_count.
113 - add $timer->remaining.
114 - add EV::loop_depth.
115 - (libev) calling unloop in fork/prepare watchers will no longer poll
116 for new events.
117 - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
118 for slightly higher accuracy.
119 - (libev) actually 0-initialise struct sigaction when installing
120 signals.
121
122 3.6 Tue Apr 28 02:50:37 CEST 2009
123 - keepalive(0) could decrease the refcount of the loop
124 permanently.
125 - add ev_suspend/ev_resume, also make ev_now_update
126 accessible via the XS API.
127 - most EV::<eventtype> constants were missing and have been
128 added :/.
129 - add EV::VERSION_MAJOR/VERSION_MINOR constants.
130 - (libev) multiple timers becoming ready within an event loop
131 iteration will be invoked in the "correct" order now.
132 - (libev) do not leave the event loop early just because we have
133 no active watchers, fixing a problem when embedding a kqueue
134 loop that has active kernel events but no registered watchers
135 (reported by blacksand blacksand).
136 - (libev) correctly zero the idx values for arrays, so destroying
137 and reinitialising the default loop actually works (patch by
138 Malek Hadj-Ali).
139 - (libev) new EV::CUSTOM revents flag for use by applications.
140 - (libev) add documentation section about priorites.
141 - (libev) add a glossary to the dcoumentation.
142 - (libev) extend the ev_fork description slightly.
143 - (libev) optimize a jump out of call_pending.
144 - t/03_keepalive could fail when there was no actual error.
145
146 3.53 Sun Feb 15 02:38:20 CET 2009
147 - (libev) on win32, the event loop creation could randomly fail
148 due to an initialised variable having the wrong value.
149 - (libev) probe for CLOCK_REALTIME support at runtime as well and
150 fall back to gettimeofday if there is an error, to support older
151 operating systems with newer header files/libraries.
152 - prefer gettimeofday over clock_gettime by default.
153
154 3.52 Wed Jan 7 21:46:14 CET 2009
155 - (libev) fix some issues in the select backend when in fd_set mode.
156 - (libev) due to a thinko, instead of disabling everything but
157 select on the borked OS X platform, everything but select was
158 allowed (reported by Emanuele Giaquinta).
159 - (libev) actually verify that local and remote port are matching in
160 libev's socketpair emulation, which makes denial-of-service
161 attacks harder (but not impossible - it's windows). Make sure
162 it even works under vista, which thinks that getpeer/sockname
163 should return fantasy port numbers.
164
165 3.51 Wed Dec 24 23:01:59 CET 2008
166 - do not cache the arguments passed to callbacks if the refcount
167 indicates that the callback has stolen them.
168 - (libev) try to avoid librt on GNU/Linux.
169 - (libev) check port_getn return value dfferently, might potentially
170 avoid problems.
171 - (libev) fix a bug with stat watchers possibly causing freezes.
172 - (libev) work around OS X 10.5 breaking poll, now select is the
173 only viable choice left on that pile of garbage.
174 - play tester whore: disable some tests that typically fail only
175 on cpan tester machines.
176
177 3.49 Wed Nov 19 11:26:53 CET 2008
178 - fix typos in manpage (Alex Efros).
179 - increase timing even further, for the ever-overloaded cpan-tester
180 machines, and to the detriment of everybody else who wants a fast
181 make test.
182 - possible 5.6 compatibility.
183 - (libev) use inotify even on buggy kernels, but don't rely on it.
184 - (libev) use inotify only as an added hint on network filesystems.
185
186 3.48 Thu Oct 30 09:09:48 CET 2008
187 - (libev) use a generation counter to detect spurious epoll events
188 and recreate the kernel in such a case (sorry, it's slow, but
189 I didn't design epoll...).
190 - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
191 backend in some cases.
192 - (libev) use memset to initialise most arrays now and do away
193 with the init functions.
194 - speed up event callback invocation further (~15%), by
195 not creating the object reference each time.
196 - EV::sleep was documented, but not implemented. fun.
197
198 3.45 Tue Oct 21 22:20:39 CEST 2008
199 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
200 - (libev) ev_embed will now automatically follow fork.
201 - (libev) ev_once will now pass both io and timeout events to
202 the callback when both happen concurrently, instead of giving
203 one precedence.
204 - install C library documentation as EV::libev manpage (sorry, oesi).
205 - (libev) fix a minor performance bug in ev_stat handling.
206
207 3.44 Mon Sep 29 05:16:31 CEST 2008
208 - (libev) add EV::now_update and $loop->now_update.
209
210 3.431 Sun Jul 13 00:19:02 CEST 2008

217
218 3.42 Mon May 26 07:36:46 CEST 2008
219 - (libev) work around another bug in windows perls and
220 windows itself: failed connects do NOT set read or write

232 3.4 Tue May 20 21:51:55 CEST 2008
233 - (libev) work around both a windows bug and a bug in perl's
234 select on windows when not waiting for any file descriptors.
235 - bundle ev.pod into the tarball, just to increase its size
236 (and for the poor internetless person).
237
238 3.33 Sun May 18 12:43:04 CEST 2008
