Revision history for Perl extension EV

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

        - e_new wasn't declared static (causing very minor .so bloat).
        - replace more old api names by new ones.

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.

        - (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).

          König).

2.0  Sat Dec 22 17:47:03 CET 2007

        - use a slightly different include file name strategy.
        - get rid of (unused) libevent emulation.

1.85 Fri Dec 14 20:32:40 CET 2007
        - further optimise epoll backend by adding a heuristic that

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.

        - 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.

1	root	1.143	Revision history for Perl extension EV
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	1.207	- e_new wasn't declared static (causing very minor .so bloat).
7	root	1.208	- replace more old api names by new ones.
8	root	1.206
9	root	1.205	4.03 Tue Jan 11 14:51:05 CET 2011
10	root	1.203	- do not avoid the clock_gettime call on GNU/Linux anymore, as EV
11			links against -lpthread anyways - as a result, EV might now take
12			advantage of fast userspace clock_gettime implementations,
13			but also links against -lrt.
14	root	1.204	- (libev) lots of event port bug workarounds.
15			- (libev) officially support files in I/O watchers.
16			- (libev) new function ev_feed_signal.
17			- fix documentation parts still refering to the 3.x API.
18	root	1.203
19	root	1.202	4.02 Thu Dec 30 08:27:41 CET 2010
20			- the revents argument did not stringify correctly, as only the
21			numeric value was updated, while the string value was kept from
22			previous invocations.
23
24	root	1.201	4.01 Sun Dec 5 12:42:13 CET 2010
25	root	1.197	- fully support EV_COMPAT3=0.
26	root	1.198	- default_fork was stupidly defined as inline.
27	root	1.199	- ask cpan to upgrade AnyEvent if < 5.29.
28	root	1.200	- support EV_EXTRA_DEFS during configuration.
29	root	1.201	- support -DEV_NO_LOOPS for snakker build.
30	root	1.197
31	root	1.196	4.00 Mon Oct 25 13:30:09 CEST 2010
32	root	1.194	- many API changes, see the manual.
33	root	1.196	- (libev) lots and lots of bugfixes, see the ev documentation.
34	root	1.187	- fix a bug where inotify usage would parse the same event
35			multiple times, causing various forms of breakage.
36			- greatly reduce stack usage for inotify (8kb to <0.5kb).
37	root	1.189	- expose ev_depth and ev_verify via the XS API.
38	root	1.196	- implement ev_cleanup watchers.
39	root	1.188	- (libev) ev_embed_stop did not correctly stop the watcher.
40			- (libev) disable poll backend on AIX.
41			- (libev) rename EV_TIMEOUT to EV_TIMER.
42			- (libev) add section on accept() problems to the manpage.
43	root	1.191	- (libev) no child watchers on win32.
44	root	1.190	- make code more aliasing compliant, in case perl is ever
45			translated to C.
46	root	1.193	- document the EV::CHECK runtime unavailability.
47	root	1.192	- ported to minix 3.1.7.
48	root	1.187
49	root	1.186	3.9 Thu Dec 31 07:59:59 CET 2009
50	root	1.182	- disable t/07* under automatic testing.
51	root	1.183	- increase t/09* timeouts as netbsd has horribly broken
52			select/kevent that usually sleep >>0.6s instead of 0.3.
53	root	1.184	- add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
54			EV::BACKEND_ALL.
55	root	1.185	- (libev) signalfd is no longer used by default.
56			- (libev) backport inotify code to C89.
57			- (libev) inotify file descriptors could leak into child processes.
58			- (libev) ev_stat watchers could keep an errornous extra ref on the loop.
59			- (libev) take advantage of inotify_init1, if available.
60			- (libev) the signal handling pipe wasn't always initialised under windows.
61			- changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
62			- (libev) only replace ev_stat.prev when we detect an actual difference.
63	root	1.182
64	root	1.181	3.8 Sun Aug 9 15:30:10 CEST 2009
65	root	1.180	- implement $loop->signal/signal_ns.
66	root	1.181	- (libev) incompatible change: do not necessarily reset signal
67			handler to SIG_DFL when a sighandler is stopped.
68			- (libev) ev_default_destroy did not properly free or zero some
69			members, potentially causing crashes and memory corruption on
70			repated ev_default_destroy/ev_default_loop calls.
71			- (libev) take advantage of signalfd on GNU/Linux systems.
72			- (libev) document that the signal mask might be in an unspecified
73			state when using libev's signal handling.
74			- (libev) take advantage of some GNU/Linux calls to set
75			cloexec/nonblock on fd creation, to avoid race conditions.
76			- implement internal glue code to interface more efficiently
77			with AnyEvent.
78	root	1.180
79	root	1.177	3.7 Fri Jul 17 16:49:16 CEST 2009
80	root	1.171	- add EV::loop_verify and EV::loop_depth.
81	root	1.172	- use output filehandle for i/o watchers waiting
82			for EV_WRITE, otherwise input filehandle.
83			- use common schmorp.h header.
84	root	1.176	- add EV::Timer->remaining.
85	root	1.175	- allow for subclassing of EV::Loop (see the exciting
86			EV::Loop::Async module for an example).
87			- added EV::invoke_pending and EV::pending_count.
88	root	1.171
89	root	1.177	- (libev) ev_unloop and ev_loop wrongly used a global variable to
90			exit loops, instead of using a per-loop variable.
91			- (libev) the ev_set_io_collect_interval interpretation has changed.
92			- add new functionality: EV::invoke_pending, EV::pending_count.
93			- add $timer->remaining.
94			- add EV::loop_depth.
95			- (libev) calling unloop in fork/prepare watchers will no longer poll
96			for new events.
97			- (libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
98			for slightly higher accuracy.
99			- (libev) actually 0-initialise struct sigaction when installing
100			signals.
101
102	root	1.170	3.6 Tue Apr 28 02:50:37 CEST 2009
103	root	1.167	- keepalive(0) could decrease the refcount of the loop
104			permanently.
105	root	1.168	- add ev_suspend/ev_resume, also make ev_now_update
106			accessible via the XS API.
107	root	1.169	- most EV::<eventtype> constants were missing and have been
108			added :/.
109			- add EV::VERSION_MAJOR/VERSION_MINOR constants.
110			- (libev) multiple timers becoming ready within an event loop
111			iteration will be invoked in the "correct" order now.
112			- (libev) do not leave the event loop early just because we have
113			no active watchers, fixing a problem when embedding a kqueue
114			loop that has active kernel events but no registered watchers
115			(reported by blacksand blacksand).
116			- (libev) correctly zero the idx values for arrays, so destroying
117			and reinitialising the default loop actually works (patch by
118			Malek Hadj-Ali).
119			- (libev) new EV::CUSTOM revents flag for use by applications.
120			- (libev) add documentation section about priorites.
121			- (libev) add a glossary to the dcoumentation.
122			- (libev) extend the ev_fork description slightly.
123			- (libev) optimize a jump out of call_pending.
124			- t/03_keepalive could fail when there was no actual error.
125	root	1.167
126	root	1.166	3.53 Sun Feb 15 02:38:20 CET 2009
127			- (libev) on win32, the event loop creation could randomly fail
128			due to an initialised variable having the wrong value.
129	root	1.165	- (libev) probe for CLOCK_REALTIME support at runtime as well and
130			fall back to gettimeofday if there is an error, to support older
131			operating systems with newer header files/libraries.
132			- prefer gettimeofday over clock_gettime by default.
133
134	root	1.164	3.52 Wed Jan 7 21:46:14 CET 2009
135	root	1.163	- (libev) fix some issues in the select backend when in fd_set mode.
136			- (libev) due to a thinko, instead of disabling everything but
137			select on the borked OS X platform, everything but select was
138			allowed (reported by Emanuele Giaquinta).
139			- (libev) actually verify that local and remote port are matching in
140			libev's socketpair emulation, which makes denial-of-service
141			attacks harder (but not impossible - it's windows). Make sure
142			it even works under vista, which thinks that getpeer/sockname
143			should return fantasy port numbers.
144
145	root	1.162	3.51 Wed Dec 24 23:01:59 CET 2008
146	root	1.161	- do not cache the arguments passed to callbacks if the refcount
147			indicates that the callback has stolen them.
148	root	1.159	- (libev) try to avoid librt on GNU/Linux.
149	root	1.160	- (libev) check port_getn return value dfferently, might potentially
150			avoid problems.
151	root	1.162	- (libev) fix a bug with stat watchers possibly causing freezes.
152			- (libev) work around OS X 10.5 breaking poll, now select is the
153			only viable choice left on that pile of garbage.
154	root	1.161	- play tester whore: disable some tests that typically fail only
155			on cpan tester machines.
156	root	1.159
157	root	1.158	3.49 Wed Nov 19 11:26:53 CET 2008
158	root	1.155	- fix typos in manpage (Alex Efros).
159	root	1.156	- increase timing even further, for the ever-overloaded cpan-tester
160			machines, and to the detriment of everybody else who wants a fast
161			make test.
162	root	1.157	- possible 5.6 compatibility.
163	root	1.158	- (libev) use inotify even on buggy kernels, but don't rely on it.

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

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