[ViewVC] Annotation of: cvs/AnyEvent/Changes

Revision history for Perl extension AnyEvent.

        - add some recommends to the META.yml.
        - added a a regex read type to AnyEvent::Handle.
        - always croak in on_error in AnyEvent::Handle.
        - document how to subclass AnyEvent::Handle.
        - implement AnyEvent::Util::fork_call.
        - 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).

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.

126	root	1.50	3.2 Thu Apr 24 10:10:40 CEST 2008
127	root	1.51	- do not die when anyevent watchers are destroyed while running callbacks
128			in the pureperl backend (could only happen when two watchers are registered
129			for the same fh/poll combo).
130			- support autoloading for child watchers, was broken in all versions.
131	root	1.47	- implement PERL_ANYEVENT_MODEL env variable.
132	root	1.49	- (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
133			- (experimental) implement interface to the Qt module (cannot be autoprobed).
134	root	1.52	- this release is IO:AnyEvent-proof.
135	root	1.47
136	root	1.46	3.12 Tue Apr 22 07:11:46 CEST 2008
137			- reinstate AUTHOR section that got lost somehow.
138			- do not hang in the testsuite with badly broken perls (activestate,
139			strawberry...), but instead diagnose the problem and continue.
140			- use INT instead of CHLD in an attempt to support broken windows perls
141			better (this decreases the test quality, unfortunately).
142			- do not send the signal to the process group
143			(no problem for CHLD, bad for INT :).
144
145	root	1.45	3.11 Sat Apr 19 06:57:31 CEST 2008
146			- major documentation rework.
147			- document the fact that child watchers only watch for zombies.
148			- fix the child watcher example.
149
150	root	1.43	3.1 Wed Apr 16 17:09:01 CEST 2008
151	root	1.40	- work around recurring bugs in Tk by dup'ing filehandles, the
152	root	1.43	only method with good success chances on Tk (the bugs apparently
153			don't get fixed anytime soon).
154	root	1.42	- lift the restriction of only one watcher per fh direction
155			(as the Tk bug workaround also lifts it and only Tk imposed
156			such strong limits).
157	root	1.41	- changed probe order to prefer coro adaptors.
158			- explain why recursion into the event loop is not supported
159			unless the backend supports it (only Coro::EV does without
160			any restrictions...).
161			- add simple manpages for all backend modules.
162	root	1.40
163	root	1.39	3.0 Mon Apr 7 21:30:23 CEST 2008
164	root	1.38	- Coro::Signal changed semantics, roll our own, also cleaning
165			up the Coro implementation in general.
166			- rename Coro backend to CoroEvent.
167			- add some decision helping paragraph to the manpage that should
168	root	1.44	help people to decide whether AnyEvent is the right thing for them.
169	root	1.38
170	root	1.37	2.9 Mon Jan 28 13:31:54 CET 2008
171			- update for EV 3.0 API changes.
172
173	root	1.36	2.8 Sun Nov 25 15:06:03 CET 2007
174			- waitpid can validly return 0. accept this fact of life
175			instead of reporting it to any watchers.
176
177	root	1.35	2.7 Fri Nov 23 11:41:14 CET 2007
178	root	1.34	- force use of AnyEvent::Impl::Perl in testsuite, there is
179			too much breakage outside AnyEvent.
180	root	1.35	- deliver signals synchronously in AnyEvent::Impl::Perl
181			or any other event loop that relies on AnyEvents child
182			watcher emulation. Could help with hanging testsuite
183			(except when Event or EV are installed).
184	root	1.34
185	root	1.33	2.6 Fri Nov 9 20:36:35 CET 2007
186	root	1.32	- fix bug in testsuite.
187			- move EV adaptor modules to AnyEvent.
188			- add Coro+EV adaptor module.
189	root	1.26
190	root	1.31	2.55 Tue Nov 6 17:41:32 CET 2007
191	root	1.27	- add EV to the list of supported event models.
192	root	1.30	- do not auto-reset pid watchers, pass pid and status to them.
193	root	1.29	- allow a pid of zero to watch for all children in child watchers.
194	root	1.27
195	root	1.25	2.54 Wed Jul 18 17:36:23 CEST 2007
196			- work around a perl bug that results in
197			BEGIN not safe after errors--compilation aborted without
198			any discernible reason or error message by once
199			again not use'ing strict.
200
201	root	1.24	2.53 Sun Jul 8 10:51:53 CEST 2007
202			- make Glib interface work again (spotted by elmex).
203
204	root	1.22	2.52 Wed Mar 7 18:36:16 CET 2007
205			- child watchers stopped working permanently when
206	root	1.23	all current child watchers were destroyed.
207	root	1.22
208	root	1.21	2.51 Mon Dec 11 21:33:24 CET 2006
209			- work around bugs in perl where eval "require Module" returns
210			true even if the module couldn't be loaded :/.
211
212	root	1.20	2.5 Mon Dec 11 02:15:28 CET 2006
213	root	1.19	- avoid $AUTOLOAD because many perls corrupt it.
214	root	1.20	- AnyEvent::detect forces autodetection.
215			- implement signal watchers (experimental)
216			(Tk does not support async signals (<= 804.027 at least),
217			so they might get delayed indefinitely on Tk).
218			- implement child watchers (experimental).
219			- moved default condvar implementation into base module, simplifying
220			most implementation modules.
221	root	1.14
222	root	1.18	2.1 Fri Nov 24 15:50:48 CET 2006
223	root	1.16	- better docs.
224			- simple testsuite.
225	root	1.17	- added AnyEvent->one_event method for special purposes.
226	root	1.16
227	root	1.15	2.0 Wed Nov 1 02:21:30 CET 2006
228	root	1.13	- INCOMPATIBLE CHANGE: poll can now either be "r" or "w" but not both.
229			- INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
230			- EXPERIMENTAL:
231			new pure-perl model added, AnyEvent now always finds a suitable
232			event model.
233	root	1.12	- improved documentation.
234			- reduced cpu overhead.
235
236	root	1.11	1.02 Fri Jan 13 14:15:40 CET 2006
237			- add COPYING to clarify license.
238
239	root	1.10	1.01 Sun Jan 8 05:48:09 CET 2006
240			- correctly cancel Event timers, avoid memory leaks.
241
242	root	1.9	1.0 Sun Jan 8 05:40:58 CET 2006
243	root	1.8	- allow third-party interfaces to be added at runtime.
244			- fix version number.
245
246	root	1.7	0.9 Fri Dec 30 02:25:41 CET 2005
247	root	1.6	- fixed errors in the documentation.
248	root	1.7	- going back to using $VERSION as "load check",
249			as suggested by Jörn Reder. Let's see why I stopped using
250			this method.
251			- add 'hup' to the list of events to receive for glib
252			and generate 'rw' events for it, as some versions of
253			glib seem to require this, while this breaks other
254			(older) versions of glib.
255			- implemented PERL_ANYEVENT_VERBOSE env variable.
256	root	1.6
257	root	1.5	0.3 Sun Dec 4 10:43:33 CET 2005
258			- no changes to the code.
259			- fixed documentation.
260			- clarified some corner cases.
261			- vastly improved documentation with a long example.
262
263	root	1.3	0.2 Thu Dec 1 22:18:49 CET 2005
264	root	1.44	- check whether a valid method was called, to avoid endless loops.
265	root	1.4	- move condvars into their own class (cleaner, safer).
266			- don't die when some modules are not available.
267			- Tk is too broken to allow for words. Will work once Tk works.
268	root	1.3
269	root	1.2	0.1 Thu Dec 1 19:44:57 CET 2005
270			- spiced up and cleaned up for release.
271
272	root	1.1	0.01 Tue Sep 21 18:12:09 CEST 2004
273			- original version; copied from Convert::Scalar.
