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

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

235
236 3.4 Tue May 20 21:51:55 CEST 2008
237 - (libev) work around both a windows bug and a bug in perl's
238 select on windows when not waiting for any file descriptors.
239 - bundle ev.pod into the tarball, just to increase its size
240 (and for the poor internetless person).
241
242 3.33 Sun May 18 12:43:04 CEST 2008
243 - (libev) use numerous enhancements such as a more
