[ViewVC] Annotation of: cvs/AnyEvent/Changes

Revision history for Perl extension AnyEvent.

        - 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.

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