Revision history for Perl extension AnyEvent.

4.151 Fri Jun  6 17:34:24 CEST 2008
        - make sure specifying _only_ on_read and never pushing reads
          works.

4.15 Fri Jun  6 13:00:46 CEST 2008
        - the pure perl backend would keep some watchers alive when more than
          one watcher was registered for the same fd.
        - new "packstring" and "storable" read and write types
          for AnyEvent::Handle.
        - allow on_eof handler to be called after on_error with EPIPE returns.
        - do not immediately call on_read callback in handle constructor.

4.14 Thu Jun  5 20:29:31 CEST 2008
        - Fixed a bug in DNS SRV priority sorting.
        - AnyEvent::Util::guard now reports runtime errors while
          executing the guard block as warnings.
        - handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.

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.

61			could die. this has been fixed.
62			- plug a probable memleak in the DNS vc code.
63			- use configured timeout also for VC request phase.
64	root	1.139	- implement timeout and max_outstanding methods
65			for resolver class.
66	root	1.140	- update version numbers in all modules.
67	root	1.129
68	root	1.128	4.1 Thu May 29 05:45:40 CEST 2008
69	root	1.123	- INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address
70			which mirrors their purpose better (old names still available
71			for a while). Also moved AnyEvent::DNS::addr to
72			AnyEvent::Socket::resolve_sockaddr.
73	root	1.127	- implement AnyEvent->time and AnyEvent->now.
74	root	1.124	- fix IPv6 support in pack_sockaddr.
75	root	1.123	- officially un-experimentalise all newly introduced code.
76			- support unix domain sockets everywhere by specifying
77			a host of "unix/" and the pathname as service.
78	root	1.126	- implement an activity timeout in AnyEvent::Handle.
79	root	1.122	- added a regex read type to AnyEvent::Handle.
80			- added a json read/write type to AnyEvent::Handle.
81	root	1.118	- always croak in on_error in AnyEvent::Handle.
82			- document how to subclass AnyEvent::Handle.
83	root	1.120	- implement AnyEvent::Util::fork_call.
84	root	1.127	- add support for IPv6 nameservers and nameserver statements.
85	root	1.121	- work around _yet_ _another_ windows perl bug in where empty
86			select masks cause errors in the pure perl backend (this
87			workaround cannot be implemented for the other event loops,
88			but EV also works around this).
89	root	1.123	- supply AnyEvent::Socket::address_type and make good use of it.
90	root	1.122	- clarify and fix the Handle documentation w.r.t $self vs. $handle
91			vs. callback arguments.
92	root	1.127	- add some recommends to the META.yml.
93	root	1.117
94	root	1.116	4.05 Mon May 26 19:44:06 CEST 2008
95			- some platforms ignore the rfc and prepend an extra sa_len member to
96			the sockaddr structure, cater for those. also use sockaddr_family,
97			didn't know it was there, but comes in handy for the workaround.
98	root	1.114	- undo the import WIN32 hack.
99
100	root	1.113	4.04 Mon May 26 08:03:31 CEST 2008
101	root	1.109	- try to work around yet another windows bug: failed connects are reported
102	root	1.110	as if it were out-of-band data. windows users: you suck. Only
103			EV, Glib, Event and the pure perl backend can handle this condition.
104	root	1.111	- optimize write algorithm in AnyEvent::Handle.
105	root	1.106	- properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
106	root	1.112	- tcp_connect now properly iterates through all targets.
107	root	1.104	- check wether IPv6 sockets can actually be created, otherwise, disable ipv6
108	root	1.114	support entirely. also hardcode some AF_INET6 constants for the
109	root	1.107	sake of perl 5.8.
110	root	1.106	- vastly improved nameserver/suffix detection algorithm for windows
111			(still a hack...)
112			- try to use a fallback dns server if no dns servers could be found.
113	root	1.108	- splatter around some local $SIG{__DIE__}'s to work around bad
114			die handlers.
115	root	1.104
116	root	1.102	4.03 Sun May 25 05:05:57 CEST 2008
117	root	1.100	- work around perl bugs on windows, where perl returns undocumented
118			error codes for sysread, syswrite etc.
119	root	1.96	- fix AnyEvent::Handle::unshift_read to really unshift and not push.
120	root	1.97	- AnyEvent::Handle could sometimes stumble over 0-byte writes.

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

327	root	1.7	0.9 Fri Dec 30 02:25:41 CET 2005
328	root	1.6	- fixed errors in the documentation.
329	root	1.7	- going back to using $VERSION as "load check",
330			as suggested by Jörn Reder. Let's see why I stopped using
331			this method.
332			- add 'hup' to the list of events to receive for glib
333			and generate 'rw' events for it, as some versions of
334			glib seem to require this, while this breaks other
335			(older) versions of glib.
336			- implemented PERL_ANYEVENT_VERBOSE env variable.
337	root	1.6
338	root	1.5	0.3 Sun Dec 4 10:43:33 CET 2005
339			- no changes to the code.
340			- fixed documentation.
341			- clarified some corner cases.
342			- vastly improved documentation with a long example.
343
344	root	1.3	0.2 Thu Dec 1 22:18:49 CET 2005
345	root	1.44	- check whether a valid method was called, to avoid endless loops.
346	root	1.4	- move condvars into their own class (cleaner, safer).
347			- don't die when some modules are not available.
348			- Tk is too broken to allow for words. Will work once Tk works.
349	root	1.3
350	root	1.2	0.1 Thu Dec 1 19:44:57 CET 2005
351			- spiced up and cleaned up for release.
