[ViewVC] Annotation of: cvs/AnyEvent/Changes

Revision history for Perl extension AnyEvent.

        - document the first parameter passed to condvar callbacks to be
          the callback.
        - add AnyEvent::Socket::{ntoa,aton} aliases.
        - optimize the AE::Handle->push_read (line ..) for the default
          eol marker.

4.22 Sun Jul 20 16:34:13 CEST 2008
        - new function AnyEvent::Socket::parse_hostport.
        - as the bulkheads at microsoft can't even get getprotobyname reliably
          working on their shitty fucking broken os we need to hardcode
          some common protocol numbers in AnyEvent::Socket. How can
          people even bother with such a pile of shit as windows.

4.21 Thu Jul 17 14:40:05 CEST 2008
        - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
          which is incompatible to previous invocation syntax.
        - work around more windows perl bugs in fork_call. I cannot imagine
          why anybody would bother implementing fork in such an obviously
          unusable way.
        - avoid calling $do_retry if the request has already finished in
          AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
          K. Sharifulin).

4.2  Sat Jul 12 22:42:11 CEST 2008
        - support an "interval" argument for repeating timers.
        - fix a bug in the pure perl event loop that caused timers to
          be delayed under some circumstances.
        - implement optional argument checking via PERL_ANYEVENT_STRICT.
        - not importing anything from Event causes it to malfunction
          and not use Time::HiRes, work around this bug.
        - more bug workarounds against the endlessly broken Tk module,
          seems to work now on 32 bit machines, but less so on 64 bit.
        - minor optimisations applied to most backends.

4.161 Fri Jul  4 14:24:48 CEST 2008
        - fixed the t/handle/02_write.t, it read after write, with the
          assumption that all data could be written before read
          (reported by Jim Razmus).

4.160 Thu Jul  3 04:02:21 CEST 2008
        - re-registering signal watchers after unregistering one did
          not work if a backend falls back on AnyEvent's default
          implementation (also affected child watchers).
        - new AnyEvent::Handle options: autocork and no_delay.

4.152 Sun Jun 22 14:15:44 CEST 2008
        - allow for 32-bit perls that implement shifts differently
          on different architectures in parse_ipv4 (reported and
          analysed by Keiichi DAIBA).

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.

16	root	1.173	4.21 Thu Jul 17 14:40:05 CEST 2008
17	root	1.171	- INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
18			which is incompatible to previous invocation syntax.
19	root	1.172	- work around more windows perl bugs in fork_call. I cannot imagine
20			why anybody would bother implementing fork in such an obviously
21			unusable way.
22			- avoid calling $do_retry if the request has already finished in
23			AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
24			K. Sharifulin).
25	root	1.170
26	root	1.169	4.2 Sat Jul 12 22:42:11 CEST 2008
27	root	1.165	- support an "interval" argument for repeating timers.
28	root	1.164	- fix a bug in the pure perl event loop that caused timers to
29			be delayed under some circumstances.
30	root	1.167	- implement optional argument checking via PERL_ANYEVENT_STRICT.
31	root	1.169	- not importing anything from Event causes it to malfunction
32			and not use Time::HiRes, work around this bug.
33			- more bug workarounds against the endlessly broken Tk module,
34	root	1.168	seems to work now on 32 bit machines, but less so on 64 bit.
35	root	1.164	- minor optimisations applied to most backends.
36
37	root	1.163	4.161 Fri Jul 4 14:24:48 CEST 2008
38	elmex	1.162	- fixed the t/handle/02_write.t, it read after write, with the
39	root	1.163	assumption that all data could be written before read
40			(reported by Jim Razmus).

42	root	1.161	4.160 Thu Jul 3 04:02:21 CEST 2008
43	root	1.160	- re-registering signal watchers after unregistering one did
44			not work if a backend falls back on AnyEvent's default
45			implementation (also affected child watchers).
46	root	1.159	- new AnyEvent::Handle options: autocork and no_delay.
47
48	root	1.158	4.152 Sun Jun 22 14:15:44 CEST 2008
49	root	1.159	- allow for 32-bit perls that implement shifts differently
50			on different architectures in parse_ipv4 (reported and
51	root	1.158	analysed by Keiichi DAIBA).
52
53	root	1.157	4.151 Fri Jun 6 17:34:24 CEST 2008
54			- make sure specifying _only_ on_read and never pushing reads
55			works.
56
57	root	1.155	4.15 Fri Jun 6 13:00:46 CEST 2008
58	root	1.154	- the pure perl backend would keep some watchers alive when more than
59			one watcher was registered for the same fd.
60	root	1.155	- new "packstring" and "storable" read and write types
61			for AnyEvent::Handle.
62	root	1.156	- allow on_eof handler to be called after on_error with EPIPE returns.
63	root	1.153	- do not immediately call on_read callback in handle constructor.
64
65	root	1.152	4.14 Thu Jun 5 20:29:31 CEST 2008
66	elmex	1.149	- Fixed a bug in DNS SRV priority sorting.
67	root	1.150	- AnyEvent::Util::guard now reports runtime errors while
68			executing the guard block as warnings.
69	root	1.152	- handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.
70	elmex	1.149
71	root	1.148	4.13 Thu Jun 5 00:47:59 CEST 2008
72	root	1.146	- AnyEvent::DNS only followed cname chains with length 2,
73			contrary to documentation. bumped it up to 10, thanks to
74			microsoft, the current broken-dns-config-king.
75	root	1.147	- AnyEvent::DNS didn't check for socket return status
76			but instead relied on perl not creating filehandles in that
77			case - too bad it gives you a bogus file handle (reported
78			and analysed by Vladimir Timofeev).
79	root	1.145	- fix queue management logic in AnyEvent::Handle:
80			when on_read was registered, the queue was empty
81			and no progress could be made AnyEvent::Handle would
82			enter an endless loop.
83			- correctly start reading again when the handle became
84			busy again after idling.
85	root	1.146	- correctly treat tls shut-downs as EOF condition
86			(for the time being, would be nice to have a callback for that).
87	root	1.145	- correctly call eof callback under all conditions
88			(hopefully).
89	root	1.146	- the timeout callback did not expect that $self can go
90			away any time.
91	root	1.145
92	root	1.144	4.12 Tue Jun 3 10:58:04 CEST 2008

100			v4mapped and v4compat addresses.
101	root	1.129	- provide more documentation for the resolver class.
102	root	1.130	- really replace longest run of :0: by :: in format_address,
103			also properly convert :: and ::1 again.
104	root	1.134	- support NAPTR record name and decode it.
105	root	1.133	- implement random weight sampling for SRV records, as per
106			rfc 2782.
107	root	1.137	- correctly abort on srv-record targets of ".".
108			- added AnyEvent::DNS::wait_for_slot.
109	root	1.138	- in the unlikely event of a virtual circuit connection
110			being invalidated by a delayed udp reply, AnyEvent::DNS
111			could die. this has been fixed.
112			- plug a probable memleak in the DNS vc code.
113			- use configured timeout also for VC request phase.
114	root	1.139	- implement timeout and max_outstanding methods
115			for resolver class.
116	root	1.140	- update version numbers in all modules.
117	root	1.129
118	root	1.128	4.1 Thu May 29 05:45:40 CEST 2008
119	root	1.123	- INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address
120			which mirrors their purpose better (old names still available
121			for a while). Also moved AnyEvent::DNS::addr to
122			AnyEvent::Socket::resolve_sockaddr.
123	root	1.127	- implement AnyEvent->time and AnyEvent->now.
124	root	1.124	- fix IPv6 support in pack_sockaddr.
125	root	1.123	- officially un-experimentalise all newly introduced code.
126			- support unix domain sockets everywhere by specifying
127			a host of "unix/" and the pathname as service.
128	root	1.126	- implement an activity timeout in AnyEvent::Handle.
129	root	1.122	- added a regex read type to AnyEvent::Handle.
130			- added a json read/write type to AnyEvent::Handle.

132			- document how to subclass AnyEvent::Handle.
133	root	1.120	- implement AnyEvent::Util::fork_call.
134	root	1.127	- add support for IPv6 nameservers and nameserver statements.
135	root	1.121	- work around _yet_ _another_ windows perl bug in where empty
136			select masks cause errors in the pure perl backend (this
137			workaround cannot be implemented for the other event loops,
138			but EV also works around this).
139	root	1.123	- supply AnyEvent::Socket::address_type and make good use of it.
140	root	1.122	- clarify and fix the Handle documentation w.r.t $self vs. $handle
141			vs. callback arguments.
142	root	1.127	- add some recommends to the META.yml.
143	root	1.117
144	root	1.116	4.05 Mon May 26 19:44:06 CEST 2008
145			- some platforms ignore the rfc and prepend an extra sa_len member to
146			the sockaddr structure, cater for those. also use sockaddr_family,
147			didn't know it was there, but comes in handy for the workaround.
148	root	1.114	- undo the import WIN32 hack.
149
150	root	1.113	4.04 Mon May 26 08:03:31 CEST 2008
151	root	1.109	- try to work around yet another windows bug: failed connects are reported
152	root	1.110	as if it were out-of-band data. windows users: you suck. Only
153			EV, Glib, Event and the pure perl backend can handle this condition.
154	root	1.111	- optimize write algorithm in AnyEvent::Handle.
155	root	1.106	- properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
156	root	1.112	- tcp_connect now properly iterates through all targets.
157	root	1.104	- check wether IPv6 sockets can actually be created, otherwise, disable ipv6
158	root	1.114	support entirely. also hardcode some AF_INET6 constants for the
159	root	1.107	sake of perl 5.8.
160	root	1.106	- vastly improved nameserver/suffix detection algorithm for windows
161			(still a hack...)
162			- try to use a fallback dns server if no dns servers could be found.
163	root	1.108	- splatter around some local $SIG{__DIE__}'s to work around bad
164			die handlers.
165	root	1.104
166	root	1.102	4.03 Sun May 25 05:05:57 CEST 2008
167	root	1.100	- work around perl bugs on windows, where perl returns undocumented
168			error codes for sysread, syswrite etc.
169	root	1.96	- fix AnyEvent::Handle::unshift_read to really unshift and not push.
170	root	1.97	- AnyEvent::Handle could sometimes stumble over 0-byte writes.

172	root	1.100	- updated documentation.
173	root	1.103	- lots of workarounds for perl 5.8 quirks.
174	root	1.98	- implement a more flexible type system for both reads and writes
175			in AnyEvent::Handle.
176	root	1.101	- support IPv6 in tcp_server.
177			- pass local hostname and port to the prepare callback in tcp_server.
178	root	1.99	- make types extendable in AnyEvent::Handle.
179	root	1.100	- croak, not die, in AnyEvent::Handle;
180	root	1.96
181	root	1.95	4.0 Sat May 24 19:58:08 CEST 2008
182	root	1.88	- added (experimental) AnyEvent::DNS module.
183			- added (experimental) AnyEvent::Socket module.
184	root	1.93	- added (experiemntal) support for TLS/SSL in AnyEvent::Handle.
185	root	1.90	- make condvar->end call ->send as documented.
186			- make condvar constructor support the documented cb => argument.
187	root	1.94	- overload condvars so you can use them instead of code references.
188	root	1.93	- support more of the POSIX forms instead of a pure dotted quad for
189	root	1.89	verbatim ip addresses.
190	root	1.88	- AnyEvent::Socket::inet_aton will use AnyEvent::DNS now and not fork anymore.
191	root	1.87	- try very hard not to freeze on broken windows perls.
192	root	1.86	- make on_eof optional in AnyEvent::Handle.
193	root	1.83	- support service names in tcp_connect and tcp_server.
194	root	1.84	- work around netbsd/openbsd bug causing unix sockets not to
195	root	1.121	become writable until empty.
196	root	1.81	- only make a dummy read for error detection when getpeername
197			returns ENOTCONN.
198	root	1.82	- defend AnyEvent::Util::inet_aton against Coro::LWP brutal
199			override.
200	root	1.91	- new AnyEvent::Guard::cancel.
201	root	1.81
202	root	1.80	3.5 Sat May 17 23:17:14 CEST 2008
203	root	1.79	- gracefully deal with systems not defining CLOCK_MONOTONIC
204			(as opposed to not supporting the clock itself, which worked in 3.41).
205	root	1.77	- added AnyEvent::Util::tcp_connect and AnyEvent::Util::tcp_server
206			helpers, to replace the ill-designed AnyEvent::Socket class.
207			- added some examples (eg/connect, eg/handle).
208			- added AnyEvent::Util::guard.
209			- AnyEvent::Util now exports most of its functions.
210	elmex	1.74	- fixed a bug in *_read_chunk, where the callback was called with $self as
211			first and second argument.
212	root	1.77	- simplified and fixed regex handling in AnyEvent::Handle::*_read_line.
213	root	1.72	- fix manpage condvars examples to use new syntax.
214	root	1.78	- considerably improve inet_aton with EV::ADNS backend to support
215			cname chains (common dns configuration bug, e.g. with www.google.de)
216			and aaaa records if no a record could be found.
217	root	1.72
218	root	1.71	3.41 Sun May 11 19:53:13 CEST 2008
219			- work around a bug in perl 5.8.8's local. Reported by Yi Ma Mao.
220
221	root	1.70	3.4 Sun May 11 00:29:25 CEST 2008
222			- complete re-implementation of condvars with a hopefully much mroe useful
223			API (backward compatible functions exist but are undocumented).
224	root	1.69	- AnyEvent::Handle fully rewritten with a hopefully more powerful API
225			(still subject to change).
226	root	1.63	- take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl.
227	root	1.68	- provide AnyEvent::post_detect and @AnyEvent::post_detect, which
228	root	1.67	allows module authors to avoid forcing event loop detection.
229			(used by Coro::AIO, Coro::BDB, Coro::AnyEvent for example).
230	root	1.66	- remove coro backends: Coro now provides generic support for AnyEvent
231			via Coro::AnyEvent.
232	root	1.63
233	root	1.62	3.3 Mon Apr 28 09:51:06 CEST 2008
234			- added AnyEvent::Handle, AnyEvent::Socket and AnyEvent::Util modules.
235	root	1.55	- fix a bug in the pure perl backend that kept watchers alive
236			when multiple watchers were registered for the same fh/poll combo.
237	root	1.54	- add a benchmark section showing AnyEvent overhead and comparing
238			the different event loops with each other.
239	root	1.56	- prefer pure perl over tk when autoprobing, as it's about as fast,
240			but doesn't crash with many watchers.
241	root	1.62	- declare Qt support non-experimental.
242	root	1.56	- clarify the confusing section about the file descriptor being
243			kept alive.
244			- document the race between loading of an event module and
245			child processes exiting.
246	root	1.53	- support POE as "backend" (with some caveats, POE is not generic
247	root	1.54	enough, and darn slow).
248	root	1.53	- support Wx and Prima through POE.
249	root	1.60	- optimise perl backend to use 20% less memory and take advantage
250	root	1.62	of typical timeout behaviour. It can now compete with
251	root	1.60	select/poll-based C event loops in most cases (it is usually
252			faster than Event and Glib :).
253	root	1.59	- roughly cut EV memory use in half and increase its speed by 30%,
254	root	1.62	by removing undocumented functionality. Did something similar
255			to other event loops where possible.
256	root	1.53
257	root	1.50	3.2 Thu Apr 24 10:10:40 CEST 2008
258	root	1.51	- do not die when anyevent watchers are destroyed while running callbacks
259			in the pureperl backend (could only happen when two watchers are registered
260			for the same fh/poll combo).
261			- support autoloading for child watchers, was broken in all versions.
262	root	1.47	- implement PERL_ANYEVENT_MODEL env variable.
263	root	1.49	- (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
264			- (experimental) implement interface to the Qt module (cannot be autoprobed).
265	root	1.52	- this release is IO:AnyEvent-proof.
266	root	1.47
267	root	1.46	3.12 Tue Apr 22 07:11:46 CEST 2008
268			- reinstate AUTHOR section that got lost somehow.
269			- do not hang in the testsuite with badly broken perls (activestate,
270			strawberry...), but instead diagnose the problem and continue.
271			- use INT instead of CHLD in an attempt to support broken windows perls
272			better (this decreases the test quality, unfortunately).
273			- do not send the signal to the process group
274			(no problem for CHLD, bad for INT :).
275
276	root	1.45	3.11 Sat Apr 19 06:57:31 CEST 2008
277			- major documentation rework.
278			- document the fact that child watchers only watch for zombies.
279			- fix the child watcher example.
280
281	root	1.43	3.1 Wed Apr 16 17:09:01 CEST 2008
282	root	1.40	- work around recurring bugs in Tk by dup'ing filehandles, the
283	root	1.43	only method with good success chances on Tk (the bugs apparently
284			don't get fixed anytime soon).
285	root	1.42	- lift the restriction of only one watcher per fh direction
286			(as the Tk bug workaround also lifts it and only Tk imposed
287			such strong limits).
288	root	1.41	- changed probe order to prefer coro adaptors.
289			- explain why recursion into the event loop is not supported
290			unless the backend supports it (only Coro::EV does without
291			any restrictions...).
292			- add simple manpages for all backend modules.
293	root	1.40
294	root	1.39	3.0 Mon Apr 7 21:30:23 CEST 2008
295	root	1.38	- Coro::Signal changed semantics, roll our own, also cleaning
296			up the Coro implementation in general.
297			- rename Coro backend to CoroEvent.
298			- add some decision helping paragraph to the manpage that should
299	root	1.44	help people to decide whether AnyEvent is the right thing for them.
300	root	1.38
301	root	1.37	2.9 Mon Jan 28 13:31:54 CET 2008
302			- update for EV 3.0 API changes.
303
304	root	1.36	2.8 Sun Nov 25 15:06:03 CET 2007
305			- waitpid can validly return 0. accept this fact of life
306			instead of reporting it to any watchers.
307
308	root	1.35	2.7 Fri Nov 23 11:41:14 CET 2007
309	root	1.34	- force use of AnyEvent::Impl::Perl in testsuite, there is
310			too much breakage outside AnyEvent.
311	root	1.35	- deliver signals synchronously in AnyEvent::Impl::Perl
312			or any other event loop that relies on AnyEvents child
313			watcher emulation. Could help with hanging testsuite
314			(except when Event or EV are installed).
315	root	1.34
316	root	1.33	2.6 Fri Nov 9 20:36:35 CET 2007
317	root	1.32	- fix bug in testsuite.
318			- move EV adaptor modules to AnyEvent.
319			- add Coro+EV adaptor module.
320	root	1.26
321	root	1.31	2.55 Tue Nov 6 17:41:32 CET 2007
322	root	1.27	- add EV to the list of supported event models.
323	root	1.30	- do not auto-reset pid watchers, pass pid and status to them.
324	root	1.29	- allow a pid of zero to watch for all children in child watchers.
325	root	1.27
326	root	1.25	2.54 Wed Jul 18 17:36:23 CEST 2007
327			- work around a perl bug that results in
328			BEGIN not safe after errors--compilation aborted without
329			any discernible reason or error message by once
330			again not use'ing strict.
331
332	root	1.24	2.53 Sun Jul 8 10:51:53 CEST 2007
333			- make Glib interface work again (spotted by elmex).
334
335	root	1.22	2.52 Wed Mar 7 18:36:16 CET 2007
336			- child watchers stopped working permanently when
337	root	1.23	all current child watchers were destroyed.
338	root	1.22
339	root	1.21	2.51 Mon Dec 11 21:33:24 CET 2006
340			- work around bugs in perl where eval "require Module" returns
341			true even if the module couldn't be loaded :/.
342
343	root	1.20	2.5 Mon Dec 11 02:15:28 CET 2006
344	root	1.19	- avoid $AUTOLOAD because many perls corrupt it.
345	root	1.20	- AnyEvent::detect forces autodetection.
346			- implement signal watchers (experimental)
347			(Tk does not support async signals (<= 804.027 at least),
348			so they might get delayed indefinitely on Tk).
349			- implement child watchers (experimental).
350			- moved default condvar implementation into base module, simplifying
351			most implementation modules.
352	root	1.14
353	root	1.18	2.1 Fri Nov 24 15:50:48 CET 2006
354	root	1.16	- better docs.

357	root	1.16
358	root	1.15	2.0 Wed Nov 1 02:21:30 CET 2006
359	root	1.13	- INCOMPATIBLE CHANGE: poll can now either be "r" or "w" but not both.
360			- INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
361			- EXPERIMENTAL:
362			new pure-perl model added, AnyEvent now always finds a suitable
363			event model.
364	root	1.12	- improved documentation.
365			- reduced cpu overhead.
366
367	root	1.11	1.02 Fri Jan 13 14:15:40 CET 2006

378	root	1.6	- fixed errors in the documentation.
379	root	1.7	- going back to using $VERSION as "load check",
380			as suggested by Jörn Reder. Let's see why I stopped using
381			this method.
