[ViewVC] Annotation of: cvs/AnyEvent/Changes

Revision history for Perl extension AnyEvent.

4.13 Thu Jun  5 00:47:59 CEST 2008
        - AnyEvent::DNS only followed cname chains with length 2,
          contrary to documentation. bumped it up to 10, thanks to
          microsoft, the current broken-dns-config-king.
        - AnyEvent::DNS didn't check for socket return status
          but instead relied on perl not creating filehandles in that
          case - too bad it gives you a bogus file handle (reported
          and analysed by Vladimir Timofeev).
        - fix queue management logic in AnyEvent::Handle:
          when on_read was registered, the queue was empty
          and no progress could be made AnyEvent::Handle would
          enter an endless loop.
        - correctly start reading again when the handle became
          busy again after idling.
        - correctly treat tls shut-downs as EOF condition
          (for the time being, would be nice to have a callback for that).
        - correctly call eof callback under all conditions
          (hopefully).
        - the timeout callback did not expect that $self can go
          away any time.

4.12 Tue Jun  3 10:58:04 CEST 2008
        - include AnyEvent::Intro, a tutorial for anyevent,
          anyevent::socket and anyevent::handle.
        - allow more options in on_error.

4.11 Fri May 30 23:42:25 CEST 2008
        - INCOMPATIBLE CHANGE: replace ptr by real PTR lookup, provide
          reverse_lookup and reverse_verify to replace it, support
          v4mapped and v4compat addresses.
        - provide more documentation for the resolver class.
        - really replace longest run of :0: by :: in format_address,
          also properly convert :: and ::1 again.
        - support NAPTR record name and decode it.
        - implement random weight sampling for SRV records, as per
          rfc 2782.
        - correctly abort on srv-record targets of ".".
        - added AnyEvent::DNS::wait_for_slot.
        - in the unlikely event of a virtual circuit connection
          being invalidated by a delayed udp reply, AnyEvent::DNS
          could die. this has been fixed.
        - plug a probable memleak in the DNS vc code.
        - use configured timeout also for VC request phase.
        - implement timeout and max_outstanding methods
          for resolver class.
        - update version numbers in all modules.

4.1  Thu May 29 05:45:40 CEST 2008
        - INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address
          which mirrors their purpose better (old names still available
          for a while). Also moved AnyEvent::DNS::addr to
          AnyEvent::Socket::resolve_sockaddr.
        - implement AnyEvent->time and AnyEvent->now.
        - fix IPv6 support in pack_sockaddr.
        - officially un-experimentalise all newly introduced code.
        - support unix domain sockets everywhere by specifying
          a host of "unix/" and the pathname as service.
        - implement an activity timeout in AnyEvent::Handle.
        - added a regex read type to AnyEvent::Handle.
        - added a json read/write type to AnyEvent::Handle.
        - always croak in on_error in AnyEvent::Handle.
        - document how to subclass AnyEvent::Handle.
        - implement AnyEvent::Util::fork_call.
        - add support for IPv6 nameservers and nameserver statements.
        - work around _yet_ _another_ windows perl bug in where empty
          select masks cause errors in the pure perl backend (this
          workaround cannot be implemented for the other event loops,
          but EV also works around this).
        - supply AnyEvent::Socket::address_type and make good use of it.
        - clarify and fix the Handle documentation w.r.t $self vs. $handle
          vs. callback arguments.
        - add some recommends to the META.yml.

4.05 Mon May 26 19:44:06 CEST 2008
        - some platforms ignore the rfc and prepend an extra sa_len member to
          the sockaddr structure, cater for those. also use sockaddr_family,
          didn't know it was there, but comes in handy for the workaround.
        - undo the import WIN32 hack.

4.04 Mon May 26 08:03:31 CEST 2008
        - try to work around yet another windows bug: failed connects are reported
          as if it were out-of-band data. windows users: you suck. Only
          EV, Glib, Event and the pure perl backend can handle this condition.
        - optimize write algorithm in AnyEvent::Handle.
        - properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
        - tcp_connect now properly iterates through all targets.
        - check wether IPv6 sockets can actually be created, otherwise, disable ipv6
          support entirely. also hardcode some AF_INET6 constants for the
          sake of perl 5.8.
        - vastly improved nameserver/suffix detection algorithm for windows
          (still a hack...)
        - try to use a fallback dns server if no dns servers could be found.
        - splatter around some local $SIG{__DIE__}'s to work around bad
          die handlers.

4.03 Sun May 25 05:05:57 CEST 2008
        - work around perl bugs on windows, where perl returns undocumented
          error codes for sysread, syswrite etc.
        - fix AnyEvent::Handle::unshift_read to really unshift and not push.
        - AnyEvent::Handle could sometimes stumble over 0-byte writes.
        - fix unpack_sockaddr, now works for AF_INET6 sockaddr's.
        - updated documentation.
        - lots of workarounds for perl 5.8 quirks.
        - implement a more flexible type system for both reads and writes
          in AnyEvent::Handle.
        - support IPv6 in tcp_server.
        - pass local hostname and port to the prepare callback in tcp_server.
        - make types extendable in AnyEvent::Handle.
        - croak, not die, in AnyEvent::Handle;

4.0  Sat May 24 19:58:08 CEST 2008
        - added (experimental) AnyEvent::DNS module.
        - added (experimental) AnyEvent::Socket module.
        - added (experiemntal) support for TLS/SSL in AnyEvent::Handle.
        - make condvar->end call ->send as documented.
        - make condvar constructor support the documented cb => argument.
        - overload condvars so you can use them instead of code references.
        - support more of the POSIX forms instead of a pure dotted quad for
          verbatim ip addresses.
        - AnyEvent::Socket::inet_aton will use AnyEvent::DNS now and not fork anymore.
        - try very hard not to freeze on broken windows perls.
        - make on_eof optional in AnyEvent::Handle.
        - support service names in tcp_connect and tcp_server.
        - work around netbsd/openbsd bug causing unix sockets not to
          become writable until empty.
        - only make a dummy read for error detection when getpeername
          returns ENOTCONN.
        - defend AnyEvent::Util::inet_aton against Coro::LWP brutal
          override.
        - new AnyEvent::Guard::cancel.

3.5  Sat May 17 23:17:14 CEST 2008
        - gracefully deal with systems not defining CLOCK_MONOTONIC
          (as opposed to not supporting the clock itself, which worked in 3.41).
        - added AnyEvent::Util::tcp_connect and AnyEvent::Util::tcp_server
          helpers, to replace the ill-designed AnyEvent::Socket class.
        - added some examples (eg/connect, eg/handle).
        - added AnyEvent::Util::guard.
        - AnyEvent::Util now exports most of its functions.
        - fixed a bug in *_read_chunk, where the callback was called with $self as
          first and second argument.
        - simplified and fixed regex handling in AnyEvent::Handle::*_read_line.
        - fix manpage condvars examples to use new syntax.
        - considerably improve inet_aton with EV::ADNS backend to support
          cname chains (common dns configuration bug, e.g. with www.google.de)
          and aaaa records if no a record could be found.

3.41 Sun May 11 19:53:13 CEST 2008
        - work around a bug in perl 5.8.8's local. Reported by Yi Ma Mao.

3.4  Sun May 11 00:29:25 CEST 2008
        - complete re-implementation of condvars with a hopefully much mroe useful
          API (backward compatible functions exist but are undocumented).
        - AnyEvent::Handle fully rewritten with a hopefully more powerful API
          (still subject to change).
        - take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl.
        - provide AnyEvent::post_detect and @AnyEvent::post_detect, which
          allows module authors to avoid forcing event loop detection.
          (used by Coro::AIO, Coro::BDB, Coro::AnyEvent for example).
        - remove coro backends: Coro now provides generic support for AnyEvent
          via Coro::AnyEvent.

3.3  Mon Apr 28 09:51:06 CEST 2008
        - added AnyEvent::Handle, AnyEvent::Socket and AnyEvent::Util modules.
        - fix a bug in the pure perl backend that kept watchers alive
          when multiple watchers were registered for the same fh/poll combo.
        - add a benchmark section showing AnyEvent overhead and comparing
          the different event loops with each other.
        - prefer pure perl over tk when autoprobing, as it's about as fast,
          but doesn't crash with many watchers.
        - declare Qt support non-experimental.
        - clarify the confusing section about the file descriptor being
          kept alive.
        - document the race between loading of an event module and
          child processes exiting.
        - support POE as "backend" (with some caveats, POE is not generic
          enough, and darn slow).
        - support Wx and Prima through POE.
        - optimise perl backend to use 20% less memory and take advantage
          of typical timeout behaviour. It can now compete with
          select/poll-based C event loops in most cases (it is usually
          faster than Event and Glib :).
        - roughly cut EV memory use in half and increase its speed by 30%,
          by removing undocumented functionality. Did something similar
          to other event loops where possible.

3.2  Thu Apr 24 10:10:40 CEST 2008
        - do not die when anyevent watchers are destroyed while running callbacks
          in the pureperl backend (could only happen when two watchers are registered
          for the same fh/poll combo).
        - support autoloading for child watchers, was broken in all versions.
        - implement PERL_ANYEVENT_MODEL env variable.
        - (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
        - (experimental) implement interface to the Qt module (cannot be autoprobed).
        - this release is IO:AnyEvent-proof.

3.12 Tue Apr 22 07:11:46 CEST 2008
        - reinstate AUTHOR section that got lost somehow.
        - do not hang in the testsuite with badly broken perls (activestate,
          strawberry...), but instead diagnose the problem and continue.
        - use INT instead of CHLD in an attempt to support broken windows perls
          better (this decreases the test quality, unfortunately).
        - do not send the signal to the process group
          (no problem for CHLD, bad for INT :).

3.11 Sat Apr 19 06:57:31 CEST 2008
        - major documentation rework.
        - document the fact that child watchers only watch for zombies.
        - fix the child watcher example.

3.1  Wed Apr 16 17:09:01 CEST 2008
        - work around recurring bugs in Tk by dup'ing filehandles, the
          only method with good success chances on Tk (the bugs apparently
          don't get fixed anytime soon).
        - lift the restriction of only one watcher per fh direction
          (as the Tk bug workaround also lifts it and only Tk imposed
          such strong limits).
        - changed probe order to prefer coro adaptors.
        - explain why recursion into the event loop is not supported
          unless the backend supports it (only Coro::EV does without
          any restrictions...).
        - add simple manpages for all backend modules.

3.0  Mon Apr  7 21:30:23 CEST 2008
        - Coro::Signal changed semantics, roll our own, also cleaning
          up the Coro implementation in general.
        - rename Coro backend to CoroEvent.
        - add some decision helping paragraph to the manpage that should
          help people to decide whether AnyEvent is the right thing for them.

2.9  Mon Jan 28 13:31:54 CET 2008
        - update for EV 3.0 API changes.

2.8  Sun Nov 25 15:06:03 CET 2007
        - waitpid can validly return 0. accept this fact of life
          instead of reporting it to any watchers.

2.7  Fri Nov 23 11:41:14 CET 2007
        - force use of AnyEvent::Impl::Perl in testsuite, there is
          too much breakage outside AnyEvent.
        - deliver signals synchronously in AnyEvent::Impl::Perl
          or any other event loop that relies on AnyEvents child
          watcher emulation. *Could* help with hanging testsuite
          (except when Event or EV are installed).

2.6  Fri Nov  9 20:36:35 CET 2007
        - fix bug in testsuite.
        - move EV adaptor modules to AnyEvent.
        - add Coro+EV adaptor module.

2.55 Tue Nov  6 17:41:32 CET 2007
        - add EV to the list of supported event models.
        - do not auto-reset pid watchers, pass pid and status to them.
        - allow a pid of zero to watch for all children in child watchers.

2.54 Wed Jul 18 17:36:23 CEST 2007
        - work around a perl bug that results in
          BEGIN not safe after errors--compilation aborted without
          any discernible reason or error message by once
          again not use'ing strict.

2.53 Sun Jul  8 10:51:53 CEST 2007
        - make Glib interface work again (spotted by elmex).

2.52 Wed Mar  7 18:36:16 CET 2007
        - child watchers stopped working permanently when
          all current child watchers were destroyed.

2.51 Mon Dec 11 21:33:24 CET 2006
        - work around bugs in perl where eval "require Module" returns
          true even if the module couldn't be loaded :/.

2.5  Mon Dec 11 02:15:28 CET 2006
        - avoid $AUTOLOAD because many perls corrupt it.
        - AnyEvent::detect forces autodetection.
        - implement signal watchers (experimental)
          (Tk does not support async signals (<= 804.027 at least),
          so they might get delayed indefinitely on Tk).
        - implement child watchers (experimental).
        - moved default condvar implementation into base module, simplifying
          most implementation modules.

2.1  Fri Nov 24 15:50:48 CET 2006
        - better docs.
        - simple testsuite.
        - added AnyEvent->one_event method for special purposes.

2.0  Wed Nov  1 02:21:30 CET 2006
        - INCOMPATIBLE CHANGE: poll can now either be "r" or "w" but not both.
        - INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
        - EXPERIMENTAL:
          new pure-perl model added, AnyEvent now always finds a suitable
          event model.
        - improved documentation.
        - reduced cpu overhead.

1.02 Fri Jan 13 14:15:40 CET 2006
        - add COPYING to clarify license.

1.01 Sun Jan  8 05:48:09 CET 2006
        - correctly cancel Event timers, avoid memory leaks.

1.0  Sun Jan  8 05:40:58 CET 2006
        - allow third-party interfaces to be added at runtime.
        - fix version number.

0.9  Fri Dec 30 02:25:41 CET 2005
        - fixed errors in the documentation.
        - going back to using $VERSION as "load check",
          as suggested by Jörn Reder. Let's see why I stopped using
          this method.
        - add 'hup' to the list of events to receive for glib
          and generate 'rw' events for it, as some versions of
          glib seem to require this, while this breaks other
          (older) versions of glib.
        - implemented PERL_ANYEVENT_VERBOSE env variable.

0.3   Sun Dec  4 10:43:33 CET 2005
        - no changes to the code.
        - fixed documentation.
        - clarified some corner cases.
        - vastly improved documentation with a long example.

0.2   Thu Dec  1 22:18:49 CET 2005
        - check whether a valid method was called, to avoid endless loops.
        - move condvars into their own class (cleaner, safer).
        - don't die when some modules are not available.
        - Tk is too broken to allow for words. Will work once Tk works.

0.1   Thu Dec  1 19:44:57 CET 2005
        - spiced up and cleaned up for release.

0.01  Tue Sep 21 18:12:09 CEST 2004
        - original version; copied from Convert::Scalar.

77			- some platforms ignore the rfc and prepend an extra sa_len member to
78			the sockaddr structure, cater for those. also use sockaddr_family,
79			didn't know it was there, but comes in handy for the workaround.
80	root	1.114	- undo the import WIN32 hack.
81
82	root	1.113	4.04 Mon May 26 08:03:31 CEST 2008
83	root	1.109	- try to work around yet another windows bug: failed connects are reported
84	root	1.110	as if it were out-of-band data. windows users: you suck. Only
85			EV, Glib, Event and the pure perl backend can handle this condition.
86	root	1.111	- optimize write algorithm in AnyEvent::Handle.
87	root	1.106	- properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
88	root	1.112	- tcp_connect now properly iterates through all targets.
89	root	1.104	- check wether IPv6 sockets can actually be created, otherwise, disable ipv6
90	root	1.114	support entirely. also hardcode some AF_INET6 constants for the
91	root	1.107	sake of perl 5.8.
92	root	1.106	- vastly improved nameserver/suffix detection algorithm for windows
93			(still a hack...)
94			- try to use a fallback dns server if no dns servers could be found.
95	root	1.108	- splatter around some local $SIG{__DIE__}'s to work around bad
96			die handlers.
97	root	1.104
98	root	1.102	4.03 Sun May 25 05:05:57 CEST 2008
99	root	1.100	- work around perl bugs on windows, where perl returns undocumented
100			error codes for sysread, syswrite etc.
101	root	1.96	- fix AnyEvent::Handle::unshift_read to really unshift and not push.
102	root	1.97	- AnyEvent::Handle could sometimes stumble over 0-byte writes.
103	root	1.101	- fix unpack_sockaddr, now works for AF_INET6 sockaddr's.
104	root	1.100	- updated documentation.
105	root	1.103	- lots of workarounds for perl 5.8 quirks.
106	root	1.98	- implement a more flexible type system for both reads and writes
107			in AnyEvent::Handle.
108	root	1.101	- support IPv6 in tcp_server.
109			- pass local hostname and port to the prepare callback in tcp_server.
110	root	1.99	- make types extendable in AnyEvent::Handle.
111	root	1.100	- croak, not die, in AnyEvent::Handle;
112	root	1.96
113	root	1.95	4.0 Sat May 24 19:58:08 CEST 2008
114	root	1.88	- added (experimental) AnyEvent::DNS module.
115			- added (experimental) AnyEvent::Socket module.
116	root	1.93	- added (experiemntal) support for TLS/SSL in AnyEvent::Handle.
117	root	1.90	- make condvar->end call ->send as documented.
118			- make condvar constructor support the documented cb => argument.
119	root	1.94	- overload condvars so you can use them instead of code references.
120	root	1.93	- support more of the POSIX forms instead of a pure dotted quad for
121	root	1.89	verbatim ip addresses.
122	root	1.88	- AnyEvent::Socket::inet_aton will use AnyEvent::DNS now and not fork anymore.
123	root	1.87	- try very hard not to freeze on broken windows perls.
124	root	1.86	- make on_eof optional in AnyEvent::Handle.
125	root	1.83	- support service names in tcp_connect and tcp_server.
126	root	1.84	- work around netbsd/openbsd bug causing unix sockets not to
127	root	1.121	become writable until empty.
128	root	1.81	- only make a dummy read for error detection when getpeername
129			returns ENOTCONN.
130	root	1.82	- defend AnyEvent::Util::inet_aton against Coro::LWP brutal
131			override.
132	root	1.91	- new AnyEvent::Guard::cancel.
133	root	1.81
134	root	1.80	3.5 Sat May 17 23:17:14 CEST 2008
135	root	1.79	- gracefully deal with systems not defining CLOCK_MONOTONIC
136			(as opposed to not supporting the clock itself, which worked in 3.41).
137	root	1.77	- added AnyEvent::Util::tcp_connect and AnyEvent::Util::tcp_server
138			helpers, to replace the ill-designed AnyEvent::Socket class.
139			- added some examples (eg/connect, eg/handle).
140			- added AnyEvent::Util::guard.
141			- AnyEvent::Util now exports most of its functions.
142	elmex	1.74	- fixed a bug in *_read_chunk, where the callback was called with $self as
143			first and second argument.
144	root	1.77	- simplified and fixed regex handling in AnyEvent::Handle::*_read_line.
145	root	1.72	- fix manpage condvars examples to use new syntax.
146	root	1.78	- considerably improve inet_aton with EV::ADNS backend to support
147			cname chains (common dns configuration bug, e.g. with www.google.de)
148			and aaaa records if no a record could be found.
149	root	1.72
150	root	1.71	3.41 Sun May 11 19:53:13 CEST 2008
151			- work around a bug in perl 5.8.8's local. Reported by Yi Ma Mao.
152
153	root	1.70	3.4 Sun May 11 00:29:25 CEST 2008
154			- complete re-implementation of condvars with a hopefully much mroe useful
155			API (backward compatible functions exist but are undocumented).
156	root	1.69	- AnyEvent::Handle fully rewritten with a hopefully more powerful API
157			(still subject to change).
158	root	1.63	- take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl.
159	root	1.68	- provide AnyEvent::post_detect and @AnyEvent::post_detect, which
160	root	1.67	allows module authors to avoid forcing event loop detection.
161			(used by Coro::AIO, Coro::BDB, Coro::AnyEvent for example).
162	root	1.66	- remove coro backends: Coro now provides generic support for AnyEvent
163			via Coro::AnyEvent.
164	root	1.63
165	root	1.62	3.3 Mon Apr 28 09:51:06 CEST 2008
166			- added AnyEvent::Handle, AnyEvent::Socket and AnyEvent::Util modules.
167	root	1.55	- fix a bug in the pure perl backend that kept watchers alive
168			when multiple watchers were registered for the same fh/poll combo.
169	root	1.54	- add a benchmark section showing AnyEvent overhead and comparing
170			the different event loops with each other.
171	root	1.56	- prefer pure perl over tk when autoprobing, as it's about as fast,
172			but doesn't crash with many watchers.
173	root	1.62	- declare Qt support non-experimental.
174	root	1.56	- clarify the confusing section about the file descriptor being
175			kept alive.
176			- document the race between loading of an event module and
177			child processes exiting.
178	root	1.53	- support POE as "backend" (with some caveats, POE is not generic
179	root	1.54	enough, and darn slow).
180	root	1.53	- support Wx and Prima through POE.
181	root	1.60	- optimise perl backend to use 20% less memory and take advantage
182	root	1.62	of typical timeout behaviour. It can now compete with
183	root	1.60	select/poll-based C event loops in most cases (it is usually
184			faster than Event and Glib :).
185	root	1.59	- roughly cut EV memory use in half and increase its speed by 30%,
186	root	1.62	by removing undocumented functionality. Did something similar
187			to other event loops where possible.
188	root	1.53
189	root	1.50	3.2 Thu Apr 24 10:10:40 CEST 2008
190	root	1.51	- do not die when anyevent watchers are destroyed while running callbacks
191			in the pureperl backend (could only happen when two watchers are registered
192			for the same fh/poll combo).
193			- support autoloading for child watchers, was broken in all versions.
194	root	1.47	- implement PERL_ANYEVENT_MODEL env variable.
195	root	1.49	- (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
196			- (experimental) implement interface to the Qt module (cannot be autoprobed).
197	root	1.52	- this release is IO:AnyEvent-proof.
198	root	1.47
199	root	1.46	3.12 Tue Apr 22 07:11:46 CEST 2008
200			- reinstate AUTHOR section that got lost somehow.
201			- do not hang in the testsuite with badly broken perls (activestate,
202			strawberry...), but instead diagnose the problem and continue.
203			- use INT instead of CHLD in an attempt to support broken windows perls
204			better (this decreases the test quality, unfortunately).
205			- do not send the signal to the process group
206			(no problem for CHLD, bad for INT :).
207
208	root	1.45	3.11 Sat Apr 19 06:57:31 CEST 2008
209			- major documentation rework.
210			- document the fact that child watchers only watch for zombies.
211			- fix the child watcher example.
212
213	root	1.43	3.1 Wed Apr 16 17:09:01 CEST 2008
214	root	1.40	- work around recurring bugs in Tk by dup'ing filehandles, the
215	root	1.43	only method with good success chances on Tk (the bugs apparently
216			don't get fixed anytime soon).
217	root	1.42	- lift the restriction of only one watcher per fh direction
218			(as the Tk bug workaround also lifts it and only Tk imposed
219			such strong limits).
220	root	1.41	- changed probe order to prefer coro adaptors.
221			- explain why recursion into the event loop is not supported
222			unless the backend supports it (only Coro::EV does without
223			any restrictions...).
224			- add simple manpages for all backend modules.
225	root	1.40
226	root	1.39	3.0 Mon Apr 7 21:30:23 CEST 2008
227	root	1.38	- Coro::Signal changed semantics, roll our own, also cleaning
228			up the Coro implementation in general.
229			- rename Coro backend to CoroEvent.
230			- add some decision helping paragraph to the manpage that should
231	root	1.44	help people to decide whether AnyEvent is the right thing for them.
232	root	1.38
233	root	1.37	2.9 Mon Jan 28 13:31:54 CET 2008
234			- update for EV 3.0 API changes.
235
236	root	1.36	2.8 Sun Nov 25 15:06:03 CET 2007
237			- waitpid can validly return 0. accept this fact of life
238			instead of reporting it to any watchers.
239
240	root	1.35	2.7 Fri Nov 23 11:41:14 CET 2007
241	root	1.34	- force use of AnyEvent::Impl::Perl in testsuite, there is
242			too much breakage outside AnyEvent.
243	root	1.35	- deliver signals synchronously in AnyEvent::Impl::Perl
244			or any other event loop that relies on AnyEvents child
245			watcher emulation. Could help with hanging testsuite
246			(except when Event or EV are installed).
247	root	1.34
248	root	1.33	2.6 Fri Nov 9 20:36:35 CET 2007
249	root	1.32	- fix bug in testsuite.
250			- move EV adaptor modules to AnyEvent.
251			- add Coro+EV adaptor module.
252	root	1.26
253	root	1.31	2.55 Tue Nov 6 17:41:32 CET 2007
254	root	1.27	- add EV to the list of supported event models.
255	root	1.30	- do not auto-reset pid watchers, pass pid and status to them.
256	root	1.29	- allow a pid of zero to watch for all children in child watchers.
257	root	1.27
258	root	1.25	2.54 Wed Jul 18 17:36:23 CEST 2007
259			- work around a perl bug that results in
260			BEGIN not safe after errors--compilation aborted without
261			any discernible reason or error message by once
262			again not use'ing strict.
263
264	root	1.24	2.53 Sun Jul 8 10:51:53 CEST 2007
265			- make Glib interface work again (spotted by elmex).
266
267	root	1.22	2.52 Wed Mar 7 18:36:16 CET 2007
268			- child watchers stopped working permanently when
269	root	1.23	all current child watchers were destroyed.
270	root	1.22
271	root	1.21	2.51 Mon Dec 11 21:33:24 CET 2006
272			- work around bugs in perl where eval "require Module" returns
273			true even if the module couldn't be loaded :/.
274
275	root	1.20	2.5 Mon Dec 11 02:15:28 CET 2006
276	root	1.19	- avoid $AUTOLOAD because many perls corrupt it.
277	root	1.20	- AnyEvent::detect forces autodetection.
278			- implement signal watchers (experimental)
279			(Tk does not support async signals (<= 804.027 at least),
280			so they might get delayed indefinitely on Tk).
281			- implement child watchers (experimental).
282			- moved default condvar implementation into base module, simplifying
283			most implementation modules.
284	root	1.14
285	root	1.18	2.1 Fri Nov 24 15:50:48 CET 2006
286	root	1.16	- better docs.
287			- simple testsuite.
288	root	1.17	- added AnyEvent->one_event method for special purposes.
289	root	1.16
290	root	1.15	2.0 Wed Nov 1 02:21:30 CET 2006
291	root	1.13	- INCOMPATIBLE CHANGE: poll can now either be "r" or "w" but not both.
292			- INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
293			- EXPERIMENTAL:
294			new pure-perl model added, AnyEvent now always finds a suitable
295			event model.
296	root	1.12	- improved documentation.
297			- reduced cpu overhead.
298
299	root	1.11	1.02 Fri Jan 13 14:15:40 CET 2006
300			- add COPYING to clarify license.
301
302	root	1.10	1.01 Sun Jan 8 05:48:09 CET 2006
303			- correctly cancel Event timers, avoid memory leaks.
304
305	root	1.9	1.0 Sun Jan 8 05:40:58 CET 2006
306	root	1.8	- allow third-party interfaces to be added at runtime.
307			- fix version number.
308
309	root	1.7	0.9 Fri Dec 30 02:25:41 CET 2005
310	root	1.6	- fixed errors in the documentation.
311	root	1.7	- going back to using $VERSION as "load check",
312			as suggested by Jörn Reder. Let's see why I stopped using
313			this method.
314			- add 'hup' to the list of events to receive for glib
315			and generate 'rw' events for it, as some versions of
316			glib seem to require this, while this breaks other
317			(older) versions of glib.
318			- implemented PERL_ANYEVENT_VERBOSE env variable.
319	root	1.6
320	root	1.5	0.3 Sun Dec 4 10:43:33 CET 2005
321			- no changes to the code.
322			- fixed documentation.
323			- clarified some corner cases.
324			- vastly improved documentation with a long example.
325
326	root	1.3	0.2 Thu Dec 1 22:18:49 CET 2005
327	root	1.44	- check whether a valid method was called, to avoid endless loops.
328	root	1.4	- move condvars into their own class (cleaner, safer).
329			- don't die when some modules are not available.
330			- Tk is too broken to allow for words. Will work once Tk works.
331	root	1.3
332	root	1.2	0.1 Thu Dec 1 19:44:57 CET 2005
333			- spiced up and cleaned up for release.
334
