Revision history for Perl extension EV

Changes marked with (libev) are changes in libev, and have more
documentation in the libev Changes file.

4.03 Tue Jan 11 14:51:05 CET 2011
        - do not avoid the clock_gettime call on GNU/Linux anymore, as EV
          links against -lpthread anyways - as a result, EV might now take
          advantage of fast userspace clock_gettime implementations,
          but also links against -lrt.
        - (libev) lots of event port bug workarounds.
        - (libev) officially support files in I/O watchers.
        - (libev) new function ev_feed_signal.
        - fix documentation parts still refering to the 3.x API.

4.02 Thu Dec 30 08:27:41 CET 2010
        - the revents argument did not stringify correctly, as only the
          numeric value was updated, while the string value was kept from
          previous invocations.

4.01 Sun Dec  5 12:42:13 CET 2010
        - fully support EV_COMPAT3=0.
        - default_fork was stupidly defined as inline.
        - ask cpan to upgrade AnyEvent if < 5.29.
        - support EV_EXTRA_DEFS during configuration.
        - support -DEV_NO_LOOPS for snakker build.

4.00 Mon Oct 25 13:30:09 CEST 2010
        - many API changes, see the manual.
        - (libev) lots and lots of bugfixes, see the ev documentation.
        - fix a bug where inotify usage would parse the same event
          multiple times, causing various forms of breakage.
        - greatly reduce stack usage for inotify (8kb to <0.5kb).
        - expose ev_depth and ev_verify via the XS API.
        - implement ev_cleanup watchers.
        - (libev) ev_embed_stop did not correctly stop the watcher.
        - (libev) disable poll backend on AIX.
        - (libev) rename EV_TIMEOUT to EV_TIMER.
        - (libev) add section on accept() problems to the manpage.
        - (libev) no child watchers on win32.
        - make code more aliasing compliant, in case perl is ever
          translated to C.
        - document the EV::CHECK runtime unavailability.
        - ported to minix 3.1.7.

3.9  Thu Dec 31 07:59:59 CET 2009
        - disable t/07* under automatic testing.
        - increase t/09* timeouts as netbsd has *horribly* broken
          select/kevent that *usually* sleep >>0.6s instead of 0.3.
        - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
          EV::BACKEND_ALL.
        - (libev) signalfd is no longer used by default.
        - (libev) backport inotify code to C89.
        - (libev) inotify file descriptors could leak into child processes.
        - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
        - (libev) take advantage of inotify_init1, if available.
        - (libev) the signal handling pipe wasn't always initialised under windows.
        - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
        - (libev) only replace ev_stat.prev when we detect an actual difference.

3.8  Sun Aug  9 15:30:10 CEST 2009
        - implement $loop->signal/signal_ns.
        - (libev) incompatible change: do not necessarily reset signal
          handler to SIG_DFL when a sighandler is stopped.
        - (libev) ev_default_destroy did not properly free or zero some
          members, potentially causing crashes and memory corruption on
          repated ev_default_destroy/ev_default_loop calls.
        - (libev) take advantage of signalfd on GNU/Linux systems.
        - (libev) document that the signal mask might be in an unspecified
          state when using libev's signal handling.
        - (libev) take advantage of some GNU/Linux calls to set
          cloexec/nonblock on fd creation, to avoid race conditions.
        - implement internal glue code to interface more efficiently
          with AnyEvent.

3.7  Fri Jul 17 16:49:16 CEST 2009
        - add EV::loop_verify and EV::loop_depth.
        - use output filehandle for i/o watchers waiting
          for EV_WRITE, otherwise input filehandle.
        - use common schmorp.h header.
        - add EV::Timer->remaining.
        - allow for subclassing of EV::Loop (see the exciting
          EV::Loop::Async module for an example).
        - added EV::invoke_pending and EV::pending_count.

        - (libev) ev_unloop and ev_loop wrongly used a global variable to
          exit loops, instead of using a per-loop variable.
        - (libev) the ev_set_io_collect_interval interpretation has changed.
        - add new functionality: EV::invoke_pending, EV::pending_count.
        - add $timer->remaining.
        - add EV::loop_depth.
        - (libev) calling unloop in fork/prepare watchers will no longer poll
          for new events.
        - (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
          for slightly higher accuracy.
        - (libev) actually 0-initialise struct sigaction when installing
          signals.

3.6  Tue Apr 28 02:50:37 CEST 2009
        - keepalive(0) could decrease the refcount of the loop
          permanently.
        - add ev_suspend/ev_resume, also make ev_now_update
          accessible via the XS API.
        - most EV::<eventtype> constants were missing and have been
          added :/.
        - add EV::VERSION_MAJOR/VERSION_MINOR constants.
        - (libev) multiple timers becoming ready within an event loop
          iteration will be invoked in the "correct" order now.
        - (libev) do not leave the event loop early just because we have
          no active watchers, fixing a problem when embedding a kqueue
          loop that has active kernel events but no registered watchers
          (reported by blacksand blacksand).
        - (libev) correctly zero the idx values for arrays, so destroying
          and reinitialising the default loop actually works (patch by
          Malek Hadj-Ali).
        - (libev) new EV::CUSTOM revents flag for use by applications.
        - (libev) add documentation section about priorites.
        - (libev) add a glossary to the dcoumentation.
        - (libev) extend the ev_fork description slightly.
        - (libev) optimize a jump out of call_pending.
        - t/03_keepalive could fail when there was no actual error.

3.53 Sun Feb 15 02:38:20 CET 2009
        - (libev) on win32, the event loop creation could randomly fail
          due to an initialised variable having the wrong value.
        - (libev) probe for CLOCK_REALTIME support at runtime as well and
          fall back to gettimeofday if there is an error, to support older
          operating systems with newer header files/libraries.
        - prefer gettimeofday over clock_gettime by default.

3.52 Wed Jan  7 21:46:14 CET 2009
        - (libev) fix some issues in the select backend when in fd_set mode.
        - (libev) due to a thinko, instead of disabling everything but
          select on the borked OS X platform, everything but select was
          allowed (reported by Emanuele Giaquinta).
        - (libev) actually verify that local and remote port are matching in
          libev's socketpair emulation, which makes denial-of-service
          attacks harder (but not impossible - it's windows). Make sure
          it even works under vista, which thinks that getpeer/sockname
          should return fantasy port numbers.

3.51 Wed Dec 24 23:01:59 CET 2008
        - do not cache the arguments passed to callbacks if the refcount
          indicates that the callback has stolen them.
        - (libev) try to avoid librt on GNU/Linux.
        - (libev) check port_getn return value dfferently, might potentially
          avoid problems.
        - (libev) fix a bug with stat watchers possibly causing freezes.
        - (libev) work around OS X 10.5 breaking poll, now select is the
          only viable choice left on that pile of garbage.
        - play tester whore: disable some tests that typically fail only
          on cpan tester machines.

3.49 Wed Nov 19 11:26:53 CET 2008
        - fix typos in manpage (Alex Efros).
        - increase timing even further, for the ever-overloaded cpan-tester
          machines, and to the detriment of everybody else who wants a fast
          make test.
        - possible 5.6 compatibility.
        - (libev) use inotify even on buggy kernels, but don't rely on it.
        - (libev) use inotify only as an added hint on network filesystems.

3.48 Thu Oct 30 09:09:48 CET 2008
        - (libev) use a generation counter to detect spurious epoll events
          and recreate the kernel in such a case (sorry, it's slow, but
          I didn't design epoll...).
        - (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
          backend in some cases.
        - (libev) use memset to initialise most arrays now and do away
          with the init functions.
        - speed up event callback invocation further (~15%), by
          not creating the object reference each time.
        - EV::sleep was documented, but not implemented. fun.

3.45 Tue Oct 21 22:20:39 CEST 2008
        - (libev) disable inotify usage on linux <2.6.25 (kernel bug).
        - (libev) ev_embed will now automatically follow fork.
        - (libev) ev_once will now pass both io and timeout events to
          the callback when both happen concurrently, instead of giving
          one precedence.
        - install C library documentation as EV::libev manpage (sorry, oesi).
        - (libev) fix a minor performance bug in ev_stat handling.

3.44 Mon Sep 29 05:16:31 CEST 2008
        - (libev) add EV::now_update and $loop->now_update.

3.431 Sun Jul 13 00:19:02 CEST 2008

          Vladimir Timofeev.

3.43 Tue Jul  8 20:56:31 CEST 2008
        - disabled warnings in EV.pm, the CHECK issue is now understood
          and harmless.

3.42 Mon May 26 07:36:46 CEST 2008
        - (libev) work around another bug in windows perls and
           windows itself: failed connects do NOT set read or write
           flags in select, but this version of libev will.

3.41 Thu May 22 01:39:40 CEST 2008
        - (libev) fix many heap-related bugs (timers, periodics).
        - (libev) improve timing stability of timers and periodics.
        - expose ev_loop_verify to perl code.
        - clarify documentation for periodic reschedule callbacks.
        - verify that the passed callback argument is indeed a code
          reference, for earlier error reporting and a nice calling
          speed increase (as well as saving memory).

3.4  Tue May 20 21:51:55 CEST 2008
        - (libev) work around both a windows bug and a bug in perl's
          select on windows when not waiting for any file descriptors.
        - bundle ev.pod into the tarball, just to increase its size
          (and for the poor internetless person).
          
3.33 Sun May 18 12:43:04 CEST 2008
        - (libev) use numerous enhancements such as a more
          cache-friendly 4-heap and heap index caching for timers.

        - relax testsuite timing for the benefit of freebsd users once more.
        - fix EVAPI's ev_time and ev_sleep macros.
        - (libev) fix select backend on 64 bit architetcures.
        - (libev) ev_loop flags are now local to each invocation.

3.1  Sat Mar  8 11:41:14 CET 2008
        - add ev_sync_* and ev_fork_* to EVAPI.h.
        - provide EV::Embed->sweep method.
        - new watcher type: async (not very useful in perl).

3.0  Mon Jan 28 13:23:11 CET 2008
        - upgrade to libev-3.0.
        - change child handler to incorporate tracing flag.

        - found a minor problem in the testsuite that is only
          caught by new Test::Harness versions (reported by Andreas
          König).

2.0  Sat Dec 22 17:47:03 CET 2007
        - no longer force kqueue when enabled, enable it
          on more systems (as its now by default not used on most).
        - expose fork watchers.

        - use a slightly different include file name strategy.
        - get rid of (unused) libevent emulation.
        - 5% watcher management speedup due to callback optimisation
          when inline closures are used, 5% slowdown due to multiplicity.
        - very minimal support for dynamic event loops and embed watchers.
        - fix name of prepare start/stop methods.
        - create and export EV::sleep and EV::set_*_collect_interval.

1.85 Fri Dec 14 20:32:40 CET 2007
        - further optimise epoll backend by adding a heuristic that
          avoids EPOLL_CTL_DEL calls if possible.

        - optimise start/stop when the fd hasn't changed.

1.8  Tue Dec 11 22:17:46 CET 2007
        - API version 3:0.
        - reduced fudge factor to zero for select, poll, epoll
          and kqueue: your system better be posix-compliant
          even in its extensions :->
        - improve long-term numerical stability in periodic watchers
          by introducing a separate offset value instead of reusing at.
        - recalculate real/monotonic clocks before blocking fully
          to avoid blocking for longer than necessary.

        - fix the data method so it might work.
        - expose ev_ref/ev_unref to the C API.
        - expose ref/unref in form of the ->keepalive method to perl.
        - minor bugfixes and portability fixes.

1.2  Thu Nov 22 05:44:09 CET 2007
        - disable kqueue by default on !netbsd, as its broken on freebsd,
          darwin and openbsd and thus almost everywhere.
        - add some allowance in t/01_timer.t for the uneven monotonic
          vs. realtime clock tick on at least freebsd.

2	root	1.1
3	root	1.185	Changes marked with (libev) are changes in libev, and have more
4			documentation in the libev Changes file.
5
6	root	1.205	4.03 Tue Jan 11 14:51:05 CET 2011
7	root	1.203	- do not avoid the clock_gettime call on GNU/Linux anymore, as EV
8			links against -lpthread anyways - as a result, EV might now take
9			advantage of fast userspace clock_gettime implementations,
10			but also links against -lrt.
11	root	1.204	- (libev) lots of event port bug workarounds.
12			- (libev) officially support files in I/O watchers.
13			- (libev) new function ev_feed_signal.
14			- fix documentation parts still refering to the 3.x API.
15	root	1.203
16	root	1.202	4.02 Thu Dec 30 08:27:41 CET 2010
17			- the revents argument did not stringify correctly, as only the
18			numeric value was updated, while the string value was kept from
19			previous invocations.
20
21	root	1.201	4.01 Sun Dec 5 12:42:13 CET 2010
22	root	1.197	- fully support EV_COMPAT3=0.
23	root	1.198	- default_fork was stupidly defined as inline.
24	root	1.199	- ask cpan to upgrade AnyEvent if < 5.29.
25	root	1.200	- support EV_EXTRA_DEFS during configuration.
26	root	1.201	- support -DEV_NO_LOOPS for snakker build.
27	root	1.197
28	root	1.196	4.00 Mon Oct 25 13:30:09 CEST 2010
29	root	1.194	- many API changes, see the manual.
30	root	1.196	- (libev) lots and lots of bugfixes, see the ev documentation.
31	root	1.187	- fix a bug where inotify usage would parse the same event
32			multiple times, causing various forms of breakage.
33			- greatly reduce stack usage for inotify (8kb to <0.5kb).
34	root	1.189	- expose ev_depth and ev_verify via the XS API.
35	root	1.196	- implement ev_cleanup watchers.
36	root	1.188	- (libev) ev_embed_stop did not correctly stop the watcher.
37			- (libev) disable poll backend on AIX.
38			- (libev) rename EV_TIMEOUT to EV_TIMER.
39			- (libev) add section on accept() problems to the manpage.
40	root	1.191	- (libev) no child watchers on win32.
41	root	1.190	- make code more aliasing compliant, in case perl is ever
42			translated to C.
43	root	1.193	- document the EV::CHECK runtime unavailability.
44	root	1.192	- ported to minix 3.1.7.
45	root	1.187
46	root	1.186	3.9 Thu Dec 31 07:59:59 CET 2009
47	root	1.182	- disable t/07* under automatic testing.
48	root	1.183	- increase t/09* timeouts as netbsd has horribly broken
49			select/kevent that usually sleep >>0.6s instead of 0.3.
50	root	1.184	- add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
51			EV::BACKEND_ALL.
52	root	1.185	- (libev) signalfd is no longer used by default.
53			- (libev) backport inotify code to C89.
54			- (libev) inotify file descriptors could leak into child processes.
55			- (libev) ev_stat watchers could keep an errornous extra ref on the loop.
56			- (libev) take advantage of inotify_init1, if available.
57			- (libev) the signal handling pipe wasn't always initialised under windows.
58			- changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
59			- (libev) only replace ev_stat.prev when we detect an actual difference.

61	root	1.181	3.8 Sun Aug 9 15:30:10 CEST 2009
62	root	1.180	- implement $loop->signal/signal_ns.
63	root	1.181	- (libev) incompatible change: do not necessarily reset signal
64			handler to SIG_DFL when a sighandler is stopped.
65			- (libev) ev_default_destroy did not properly free or zero some
66			members, potentially causing crashes and memory corruption on
67			repated ev_default_destroy/ev_default_loop calls.
68			- (libev) take advantage of signalfd on GNU/Linux systems.
69			- (libev) document that the signal mask might be in an unspecified
70			state when using libev's signal handling.
71			- (libev) take advantage of some GNU/Linux calls to set
72			cloexec/nonblock on fd creation, to avoid race conditions.
73			- implement internal glue code to interface more efficiently
74			with AnyEvent.
75	root	1.180
76	root	1.177	3.7 Fri Jul 17 16:49:16 CEST 2009
77	root	1.171	- add EV::loop_verify and EV::loop_depth.
78	root	1.172	- use output filehandle for i/o watchers waiting
79			for EV_WRITE, otherwise input filehandle.
80			- use common schmorp.h header.
81	root	1.176	- add EV::Timer->remaining.
82	root	1.175	- allow for subclassing of EV::Loop (see the exciting
83			EV::Loop::Async module for an example).
84			- added EV::invoke_pending and EV::pending_count.
85	root	1.171
86	root	1.177	- (libev) ev_unloop and ev_loop wrongly used a global variable to
87			exit loops, instead of using a per-loop variable.
88			- (libev) the ev_set_io_collect_interval interpretation has changed.
89			- add new functionality: EV::invoke_pending, EV::pending_count.
90			- add $timer->remaining.
91			- add EV::loop_depth.
92			- (libev) calling unloop in fork/prepare watchers will no longer poll
93			for new events.
94			- (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
95			for slightly higher accuracy.
96			- (libev) actually 0-initialise struct sigaction when installing
97			signals.
98
99	root	1.170	3.6 Tue Apr 28 02:50:37 CEST 2009
100	root	1.167	- keepalive(0) could decrease the refcount of the loop
101			permanently.
102	root	1.168	- add ev_suspend/ev_resume, also make ev_now_update
103			accessible via the XS API.
104	root	1.169	- most EV::<eventtype> constants were missing and have been
105			added :/.
106			- add EV::VERSION_MAJOR/VERSION_MINOR constants.
107			- (libev) multiple timers becoming ready within an event loop
108			iteration will be invoked in the "correct" order now.
109			- (libev) do not leave the event loop early just because we have
110			no active watchers, fixing a problem when embedding a kqueue
111			loop that has active kernel events but no registered watchers
112			(reported by blacksand blacksand).
113			- (libev) correctly zero the idx values for arrays, so destroying
114			and reinitialising the default loop actually works (patch by
115			Malek Hadj-Ali).
116			- (libev) new EV::CUSTOM revents flag for use by applications.
117			- (libev) add documentation section about priorites.
118			- (libev) add a glossary to the dcoumentation.
119			- (libev) extend the ev_fork description slightly.
120			- (libev) optimize a jump out of call_pending.
121			- t/03_keepalive could fail when there was no actual error.
122	root	1.167
123	root	1.166	3.53 Sun Feb 15 02:38:20 CET 2009
124			- (libev) on win32, the event loop creation could randomly fail
125			due to an initialised variable having the wrong value.
126	root	1.165	- (libev) probe for CLOCK_REALTIME support at runtime as well and
127			fall back to gettimeofday if there is an error, to support older
128			operating systems with newer header files/libraries.
129			- prefer gettimeofday over clock_gettime by default.
130
131	root	1.164	3.52 Wed Jan 7 21:46:14 CET 2009
132	root	1.163	- (libev) fix some issues in the select backend when in fd_set mode.
133			- (libev) due to a thinko, instead of disabling everything but
134			select on the borked OS X platform, everything but select was
135			allowed (reported by Emanuele Giaquinta).
136			- (libev) actually verify that local and remote port are matching in
137			libev's socketpair emulation, which makes denial-of-service
138			attacks harder (but not impossible - it's windows). Make sure
139			it even works under vista, which thinks that getpeer/sockname
140			should return fantasy port numbers.
141
142	root	1.162	3.51 Wed Dec 24 23:01:59 CET 2008
143	root	1.161	- do not cache the arguments passed to callbacks if the refcount
144			indicates that the callback has stolen them.
145	root	1.159	- (libev) try to avoid librt on GNU/Linux.
146	root	1.160	- (libev) check port_getn return value dfferently, might potentially
147			avoid problems.
148	root	1.162	- (libev) fix a bug with stat watchers possibly causing freezes.
149			- (libev) work around OS X 10.5 breaking poll, now select is the
150			only viable choice left on that pile of garbage.
151	root	1.161	- play tester whore: disable some tests that typically fail only
152			on cpan tester machines.
153	root	1.159
154	root	1.158	3.49 Wed Nov 19 11:26:53 CET 2008
155	root	1.155	- fix typos in manpage (Alex Efros).
156	root	1.156	- increase timing even further, for the ever-overloaded cpan-tester
157			machines, and to the detriment of everybody else who wants a fast
158			make test.
159	root	1.157	- possible 5.6 compatibility.
160	root	1.158	- (libev) use inotify even on buggy kernels, but don't rely on it.

163	root	1.154	3.48 Thu Oct 30 09:09:48 CET 2008
164	root	1.152	- (libev) use a generation counter to detect spurious epoll events
165	root	1.151	and recreate the kernel in such a case (sorry, it's slow, but
166			I didn't design epoll...).
167	root	1.150	- (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
168			backend in some cases.
169			- (libev) use memset to initialise most arrays now and do away
170			with the init functions.
171	root	1.152	- speed up event callback invocation further (~15%), by
172	root	1.151	not creating the object reference each time.
173	root	1.153	- EV::sleep was documented, but not implemented. fun.
174	root	1.150
175			3.45 Tue Oct 21 22:20:39 CEST 2008
176			- (libev) disable inotify usage on linux <2.6.25 (kernel bug).
177	root	1.146	- (libev) ev_embed will now automatically follow fork.
178			- (libev) ev_once will now pass both io and timeout events to
179			the callback when both happen concurrently, instead of giving
180			one precedence.
181	root	1.149	- install C library documentation as EV::libev manpage (sorry, oesi).

190
191	root	1.141	3.43 Tue Jul 8 20:56:31 CEST 2008
192	root	1.140	- disabled warnings in EV.pm, the CHECK issue is now understood
193			and harmless.
194
195	root	1.139	3.42 Mon May 26 07:36:46 CEST 2008
196	root	1.138	- (libev) work around another bug in windows perls and
197			windows itself: failed connects do NOT set read or write
