[ViewVC] Annotation of: cvs/AnyEvent/Changes

Revision history for Perl extension AnyEvent.

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.

72	root	1.127	- add support for IPv6 nameservers and nameserver statements.
73	root	1.121	- work around _yet_ _another_ windows perl bug in where empty
74			select masks cause errors in the pure perl backend (this
75			workaround cannot be implemented for the other event loops,
76			but EV also works around this).
77	root	1.123	- supply AnyEvent::Socket::address_type and make good use of it.
78	root	1.122	- clarify and fix the Handle documentation w.r.t $self vs. $handle
79			vs. callback arguments.
80	root	1.127	- add some recommends to the META.yml.
81	root	1.117
82	root	1.116	4.05 Mon May 26 19:44:06 CEST 2008
83			- some platforms ignore the rfc and prepend an extra sa_len member to
84			the sockaddr structure, cater for those. also use sockaddr_family,
85			didn't know it was there, but comes in handy for the workaround.
86	root	1.114	- undo the import WIN32 hack.
87
88	root	1.113	4.04 Mon May 26 08:03:31 CEST 2008
89	root	1.109	- try to work around yet another windows bug: failed connects are reported
90	root	1.110	as if it were out-of-band data. windows users: you suck. Only
91			EV, Glib, Event and the pure perl backend can handle this condition.
92	root	1.111	- optimize write algorithm in AnyEvent::Handle.
93	root	1.106	- properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
94	root	1.112	- tcp_connect now properly iterates through all targets.
95	root	1.104	- check wether IPv6 sockets can actually be created, otherwise, disable ipv6
96	root	1.114	support entirely. also hardcode some AF_INET6 constants for the
97	root	1.107	sake of perl 5.8.
98	root	1.106	- vastly improved nameserver/suffix detection algorithm for windows
99			(still a hack...)
100			- try to use a fallback dns server if no dns servers could be found.
101	root	1.108	- splatter around some local $SIG{__DIE__}'s to work around bad
102			die handlers.
103	root	1.104
104	root	1.102	4.03 Sun May 25 05:05:57 CEST 2008
105	root	1.100	- work around perl bugs on windows, where perl returns undocumented
106			error codes for sysread, syswrite etc.
107	root	1.96	- fix AnyEvent::Handle::unshift_read to really unshift and not push.
108	root	1.97	- AnyEvent::Handle could sometimes stumble over 0-byte writes.
109	root	1.101	- fix unpack_sockaddr, now works for AF_INET6 sockaddr's.
110	root	1.100	- updated documentation.
111	root	1.103	- lots of workarounds for perl 5.8 quirks.
112	root	1.98	- implement a more flexible type system for both reads and writes
113			in AnyEvent::Handle.
114	root	1.101	- support IPv6 in tcp_server.
115			- pass local hostname and port to the prepare callback in tcp_server.
116	root	1.99	- make types extendable in AnyEvent::Handle.
117	root	1.100	- croak, not die, in AnyEvent::Handle;
118	root	1.96
119	root	1.95	4.0 Sat May 24 19:58:08 CEST 2008
120	root	1.88	- added (experimental) AnyEvent::DNS module.
121			- added (experimental) AnyEvent::Socket module.
122	root	1.93	- added (experiemntal) support for TLS/SSL in AnyEvent::Handle.
123	root	1.90	- make condvar->end call ->send as documented.
124			- make condvar constructor support the documented cb => argument.
125	root	1.94	- overload condvars so you can use them instead of code references.
126	root	1.93	- support more of the POSIX forms instead of a pure dotted quad for
127	root	1.89	verbatim ip addresses.
128	root	1.88	- AnyEvent::Socket::inet_aton will use AnyEvent::DNS now and not fork anymore.
129	root	1.87	- try very hard not to freeze on broken windows perls.
130	root	1.86	- make on_eof optional in AnyEvent::Handle.
131	root	1.83	- support service names in tcp_connect and tcp_server.
132	root	1.84	- work around netbsd/openbsd bug causing unix sockets not to
133	root	1.121	become writable until empty.
134	root	1.81	- only make a dummy read for error detection when getpeername
135			returns ENOTCONN.
136	root	1.82	- defend AnyEvent::Util::inet_aton against Coro::LWP brutal
137			override.
138	root	1.91	- new AnyEvent::Guard::cancel.
139	root	1.81
140	root	1.80	3.5 Sat May 17 23:17:14 CEST 2008
141	root	1.79	- gracefully deal with systems not defining CLOCK_MONOTONIC
142			(as opposed to not supporting the clock itself, which worked in 3.41).
143	root	1.77	- added AnyEvent::Util::tcp_connect and AnyEvent::Util::tcp_server
144			helpers, to replace the ill-designed AnyEvent::Socket class.
145			- added some examples (eg/connect, eg/handle).
146			- added AnyEvent::Util::guard.
147			- AnyEvent::Util now exports most of its functions.
148	elmex	1.74	- fixed a bug in *_read_chunk, where the callback was called with $self as
149			first and second argument.
150	root	1.77	- simplified and fixed regex handling in AnyEvent::Handle::*_read_line.
151	root	1.72	- fix manpage condvars examples to use new syntax.
152	root	1.78	- considerably improve inet_aton with EV::ADNS backend to support
153			cname chains (common dns configuration bug, e.g. with www.google.de)
154			and aaaa records if no a record could be found.
155	root	1.72
156	root	1.71	3.41 Sun May 11 19:53:13 CEST 2008
157			- work around a bug in perl 5.8.8's local. Reported by Yi Ma Mao.
158
159	root	1.70	3.4 Sun May 11 00:29:25 CEST 2008
160			- complete re-implementation of condvars with a hopefully much mroe useful
161			API (backward compatible functions exist but are undocumented).
162	root	1.69	- AnyEvent::Handle fully rewritten with a hopefully more powerful API
163			(still subject to change).
164	root	1.63	- take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl.
165	root	1.68	- provide AnyEvent::post_detect and @AnyEvent::post_detect, which
166	root	1.67	allows module authors to avoid forcing event loop detection.
167			(used by Coro::AIO, Coro::BDB, Coro::AnyEvent for example).
168	root	1.66	- remove coro backends: Coro now provides generic support for AnyEvent
169			via Coro::AnyEvent.
170	root	1.63
171	root	1.62	3.3 Mon Apr 28 09:51:06 CEST 2008
172			- added AnyEvent::Handle, AnyEvent::Socket and AnyEvent::Util modules.
173	root	1.55	- fix a bug in the pure perl backend that kept watchers alive
174			when multiple watchers were registered for the same fh/poll combo.
175	root	1.54	- add a benchmark section showing AnyEvent overhead and comparing
176			the different event loops with each other.
177	root	1.56	- prefer pure perl over tk when autoprobing, as it's about as fast,
178			but doesn't crash with many watchers.
179	root	1.62	- declare Qt support non-experimental.
180	root	1.56	- clarify the confusing section about the file descriptor being
181			kept alive.
182			- document the race between loading of an event module and
183			child processes exiting.
184	root	1.53	- support POE as "backend" (with some caveats, POE is not generic
185	root	1.54	enough, and darn slow).
186	root	1.53	- support Wx and Prima through POE.
187	root	1.60	- optimise perl backend to use 20% less memory and take advantage
188	root	1.62	of typical timeout behaviour. It can now compete with
189	root	1.60	select/poll-based C event loops in most cases (it is usually
190			faster than Event and Glib :).
191	root	1.59	- roughly cut EV memory use in half and increase its speed by 30%,
192	root	1.62	by removing undocumented functionality. Did something similar
193			to other event loops where possible.
194	root	1.53
195	root	1.50	3.2 Thu Apr 24 10:10:40 CEST 2008
196	root	1.51	- do not die when anyevent watchers are destroyed while running callbacks
197			in the pureperl backend (could only happen when two watchers are registered
198			for the same fh/poll combo).
199			- support autoloading for child watchers, was broken in all versions.
200	root	1.47	- implement PERL_ANYEVENT_MODEL env variable.
201	root	1.49	- (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
202			- (experimental) implement interface to the Qt module (cannot be autoprobed).
203	root	1.52	- this release is IO:AnyEvent-proof.
204	root	1.47
205	root	1.46	3.12 Tue Apr 22 07:11:46 CEST 2008
206			- reinstate AUTHOR section that got lost somehow.
207			- do not hang in the testsuite with badly broken perls (activestate,
208			strawberry...), but instead diagnose the problem and continue.
209			- use INT instead of CHLD in an attempt to support broken windows perls
210			better (this decreases the test quality, unfortunately).
211			- do not send the signal to the process group
212			(no problem for CHLD, bad for INT :).
213
214	root	1.45	3.11 Sat Apr 19 06:57:31 CEST 2008
215			- major documentation rework.
216			- document the fact that child watchers only watch for zombies.
217			- fix the child watcher example.
218
219	root	1.43	3.1 Wed Apr 16 17:09:01 CEST 2008
220	root	1.40	- work around recurring bugs in Tk by dup'ing filehandles, the
221	root	1.43	only method with good success chances on Tk (the bugs apparently
222			don't get fixed anytime soon).
223	root	1.42	- lift the restriction of only one watcher per fh direction
224			(as the Tk bug workaround also lifts it and only Tk imposed
225			such strong limits).
226	root	1.41	- changed probe order to prefer coro adaptors.
227			- explain why recursion into the event loop is not supported
228			unless the backend supports it (only Coro::EV does without
229			any restrictions...).
230			- add simple manpages for all backend modules.
231	root	1.40
232	root	1.39	3.0 Mon Apr 7 21:30:23 CEST 2008
233	root	1.38	- Coro::Signal changed semantics, roll our own, also cleaning
234			up the Coro implementation in general.
235			- rename Coro backend to CoroEvent.
236			- add some decision helping paragraph to the manpage that should
237	root	1.44	help people to decide whether AnyEvent is the right thing for them.
238	root	1.38
239	root	1.37	2.9 Mon Jan 28 13:31:54 CET 2008
240			- update for EV 3.0 API changes.
241
242	root	1.36	2.8 Sun Nov 25 15:06:03 CET 2007
243			- waitpid can validly return 0. accept this fact of life
244			instead of reporting it to any watchers.
245
246	root	1.35	2.7 Fri Nov 23 11:41:14 CET 2007
247	root	1.34	- force use of AnyEvent::Impl::Perl in testsuite, there is
248			too much breakage outside AnyEvent.
249	root	1.35	- deliver signals synchronously in AnyEvent::Impl::Perl
250			or any other event loop that relies on AnyEvents child
251			watcher emulation. Could help with hanging testsuite
252			(except when Event or EV are installed).
253	root	1.34
254	root	1.33	2.6 Fri Nov 9 20:36:35 CET 2007
255	root	1.32	- fix bug in testsuite.
256			- move EV adaptor modules to AnyEvent.
257			- add Coro+EV adaptor module.
258	root	1.26
259	root	1.31	2.55 Tue Nov 6 17:41:32 CET 2007
260	root	1.27	- add EV to the list of supported event models.
261	root	1.30	- do not auto-reset pid watchers, pass pid and status to them.
262	root	1.29	- allow a pid of zero to watch for all children in child watchers.
263	root	1.27
264	root	1.25	2.54 Wed Jul 18 17:36:23 CEST 2007
265			- work around a perl bug that results in
266			BEGIN not safe after errors--compilation aborted without
267			any discernible reason or error message by once
268			again not use'ing strict.
269
270	root	1.24	2.53 Sun Jul 8 10:51:53 CEST 2007
271			- make Glib interface work again (spotted by elmex).
272
273	root	1.22	2.52 Wed Mar 7 18:36:16 CET 2007
274			- child watchers stopped working permanently when
275	root	1.23	all current child watchers were destroyed.
276	root	1.22
277	root	1.21	2.51 Mon Dec 11 21:33:24 CET 2006
278			- work around bugs in perl where eval "require Module" returns
279			true even if the module couldn't be loaded :/.
280
281	root	1.20	2.5 Mon Dec 11 02:15:28 CET 2006
282	root	1.19	- avoid $AUTOLOAD because many perls corrupt it.
283	root	1.20	- AnyEvent::detect forces autodetection.
284			- implement signal watchers (experimental)
285			(Tk does not support async signals (<= 804.027 at least),
286			so they might get delayed indefinitely on Tk).
287			- implement child watchers (experimental).
288			- moved default condvar implementation into base module, simplifying
289			most implementation modules.
290	root	1.14
291	root	1.18	2.1 Fri Nov 24 15:50:48 CET 2006
292	root	1.16	- better docs.
293			- simple testsuite.
294	root	1.17	- added AnyEvent->one_event method for special purposes.
295	root	1.16
296	root	1.15	2.0 Wed Nov 1 02:21:30 CET 2006
297	root	1.13	- INCOMPATIBLE CHANGE: poll can now either be "r" or "w" but not both.
298			- INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
299			- EXPERIMENTAL:
300			new pure-perl model added, AnyEvent now always finds a suitable
301			event model.
302	root	1.12	- improved documentation.
303			- reduced cpu overhead.
304
305	root	1.11	1.02 Fri Jan 13 14:15:40 CET 2006
306			- add COPYING to clarify license.
307
308	root	1.10	1.01 Sun Jan 8 05:48:09 CET 2006
309			- correctly cancel Event timers, avoid memory leaks.
310
311	root	1.9	1.0 Sun Jan 8 05:40:58 CET 2006
312	root	1.8	- allow third-party interfaces to be added at runtime.
313			- fix version number.
314
315	root	1.7	0.9 Fri Dec 30 02:25:41 CET 2005
316	root	1.6	- fixed errors in the documentation.
317	root	1.7	- going back to using $VERSION as "load check",
318			as suggested by Jörn Reder. Let's see why I stopped using
319			this method.
320			- add 'hup' to the list of events to receive for glib
321			and generate 'rw' events for it, as some versions of
322			glib seem to require this, while this breaks other
323			(older) versions of glib.
324			- implemented PERL_ANYEVENT_VERBOSE env variable.
325	root	1.6
326	root	1.5	0.3 Sun Dec 4 10:43:33 CET 2005
327			- no changes to the code.
328			- fixed documentation.
329			- clarified some corner cases.
330			- vastly improved documentation with a long example.
331
332	root	1.3	0.2 Thu Dec 1 22:18:49 CET 2005
333	root	1.44	- check whether a valid method was called, to avoid endless loops.
334	root	1.4	- move condvars into their own class (cleaner, safer).
335			- don't die when some modules are not available.
336			- Tk is too broken to allow for words. Will work once Tk works.
337	root	1.3
338	root	1.2	0.1 Thu Dec 1 19:44:57 CET 2005
339			- spiced up and cleaned up for release.
340
