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

200 - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
201 - (libev) ev_embed will now automatically follow fork.
202 - (libev) ev_once will now pass both io and timeout events to
203 the callback when both happen concurrently, instead of giving
204 one precedence.
205 - install C library documentation as EV::libev manpage (sorry, oesi).
206 - (libev) fix a minor performance bug in ev_stat handling.
207
208 3.44 Mon Sep 29 05:16:31 CEST 2008
209 - (libev) add EV::now_update and $loop->now_update.
210
211 3.431 Sun Jul 13 00:19:02 CEST 2008

219 3.42 Mon May 26 07:36:46 CEST 2008
220 - (libev) work around another bug in windows perls and
