1 root 1.1 Revision history for Perl extension AnyEvent.
2    
3 root 1.392 TODO: docs signal for condvar
4    
5 root 1.395 - simplified and reworked the "OTHER MODULES" section.
6     - explicitly check for non-stream sockets in AE::Handle, too many
7     clueless people fell into the trap of this somehow working
8     (see the horrible AE::Handle::UDP for a good example...).
9    
10 root 1.394 5.261 Wed Apr 28 16:13:36 CEST 2010
11 root 1.393 - AF_INET6 was not properly used from Socket6 during configuration
12     time (found by Andy Grundman).
13    
14 root 1.392 5.26 Mon Apr 12 04:49:35 CEST 2010
15 root 1.389 - don't generate spurious readyness notifications when select
16     returns EINTR in the pure perl backend (analysed and testcase
17     by Bas Denissen).
18 root 1.391 - give same examples in SYNOPSIS sections of AnyEvent and AE.
19 root 1.390 - provider faster implementations for AE::time/now/now_update for
20     EV and Perl backends.
21     - provide faster AE::cv and AE::time implementations for all
22     backends.
23     - no longer support lower/mixed-case signal names (this was
24     never documented nor universally supported).
25     - some more memory µ-optimisations, and somewhat less messy
26     code to cope with both AnyEvent and AE APIs.
27 root 1.389
28 root 1.386 5.251 Sat Mar 13 00:58:21 CET 2010
29 root 1.387 - make test failed if it was run before make install on perl <=
30     5.8.8, and older versions of perl make our live very difficult,
31     so write constants.pl during Makefile.PL time.
32 root 1.386
33 root 1.384 5.25 Sat Mar 13 00:23:14 CET 2010
34 root 1.383 - fix a race condition in AnyEvent::Handle that would cause
35     a "bio_read: unsupported method" error (in _another_
36     ssl connection) after user code threw an exception.
37 root 1.385 - added AnyEvent::Handle->destroyed method.
38 root 1.376 - speed up AnyEvent::Socket::format_address and ::format_ipv6.
39 root 1.378 - the AnyEvent::Util::fh_nonblocking function worked only
40     by lucky accident on win32.
41 root 1.377 - smaller and faster AnyEvent::Util::fh_nonblocking.
42 root 1.379 - when the (required!) Time::HiRes module is missing, AnyEvent
43     did not fall back to built-in time properly.
44 root 1.381 - do not load Fcntl at runtime, saving memory and loading time.
45     - precompile a number of constants and use them instead of runtime
46     detection and eval.
47     - free detection code after detection and similar memory optimisations.
48 root 1.382 - Perl backend timer interval best effort drift has been improved
49 root 1.388 (same algorithm as EV).
50 root 1.385 - update unicode idna mapping table.
51 root 1.376
52 root 1.375 5.24 Tue Jan 5 11:39:43 CET 2010
53     - cygwin never reports errors from failed connects. 1.5 just gives
54     you continous readyness and EAGAIN, 1.7 is even more broken and
55     just hangs. work around both issues in a cygwin-specific hack.
56 root 1.374 - improve idle watcher documentation slightly.
57    
58 root 1.373 5.23 Sun Dec 20 23:48:00 CET 2009
59 root 1.372 - support IDNs in resolve_sockaddr, and therefore in tcp_connect.
60 root 1.373 - implement punycode_encode/decode, idn_nameprep,
61     idn_to_ascii and idn_to_unicode operations in AnyEvent::Util.
62 root 1.366 - provide $AE::VERSION.
63 root 1.367 - removed traces of "no strict 'refs'".
64 root 1.366
65 root 1.365 5.22 Sat Dec 5 03:51:13 CET 2009
66 root 1.358 - downgrade-or-fail in AnyEvent::Handle::push_write, to
67     diagnose encoding failures earlier and more succinctly.
68 root 1.359 (this works around bugs in perl, throwing away encoding info
69     when passing scalar data to extensions).
70 root 1.360 - add more examples to AnyEvent::Socket manpage.
71 root 1.361 - upgrade internal warning set to the same as common::sense 2.03.
72 root 1.362 - use pack "n/a*" for pre-5.8.9 perl compatibility in AnyEvent::DNS
73     (John Beppu).
74 root 1.364 - AnyEvent::Socket::inet_aton now properly supports ipv6, as documented.
75 root 1.363 - add google public dns servers to fallback server set and make sure
76     we load-balance properly between the three sets. also add all
77     fallback dns servers, not just a random one, to each dns config.
78 root 1.358
79 root 1.357 5.21 Thu Nov 19 02:48:47 CET 2009
80 root 1.356 - fix a problem where socket constants were called with parameters
81 root 1.355 (spotted by David Friedland).
82 root 1.356 - fork_call never use'd POSIX (reported by Daisuke Maki).
83 root 1.355 - improve perl 5.6 compatibility further (but it still won't work
84     unless you rip out everything but the core).
85 root 1.357 - prefer Net::DNS::Resolver over ipconfig, if installed, on win32.
86     uses 10MB of RAM, but doesn't open a console window. *sigh*.
87 root 1.355
88 root 1.354 5.202 Wed Oct 14 22:35:44 CEST 2009
89     - AnyEvent::DNS would unexpectedly clobber $_ under windows
90     (analysed by Matthias Waldorf).
91 root 1.353 - AnyEvent::Handle::run_cmd can now pass the PID of the
92     newly-created process, which is much less useful than it might
93     sound (based on patch by Yann Kerherve).
94    
95 root 1.352 5.201 Tue Sep 29 12:09:25 CEST 2009
96 root 1.350 - AnyEvent:Handle::on_starttls/on_stoptls methods were broken
97     (reported by Torsten Foertsch).
98 root 1.351 - common::sense 2.0 could cause tcp_server to throw an exception
99     (analysed by elmex).
100 root 1.350
101 root 1.349 5.2 Mon Sep 14 07:04:49 CEST 2009
102 root 1.347 - INCOMPATIBLE CHANGE: do no longer support register_read_type
103     and register_write_type in AnyEvent::Handle, instead support
104     package names (the facility was mostly abused).
105 root 1.349 - implement "packagename-as-read/write type" support in
106     AnyEvent::Handle.
107 root 1.345 - AnyEvent::Handle: new options "keepalive" and "oobinline".
108 root 1.346 - oobinline set by default to avoid security issues.
109 root 1.349 - the pure-perl event loop backend wrongly detected times() fallback
110     support (spotted by Pavel Boldin).
111 root 1.345
112 root 1.344 5.12 Tue Sep 1 20:26:50 CEST 2009
113 root 1.343 - be more lenient when parsing resolv.conf files, as some people
114     use hashmarks as comment indicator inside directives (reported
115     by Michael S. Fischer).
116     - use same set of warnings as common::sense 2.0.
117 root 1.342 - fix a potential 32 bit overflow issue due to perl having problems
118     with large hex constants in the Perl backend.
119     - do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS
120     by default.
121 root 1.343 - fix some prototypes.

123 root 1.343 - replace opendns fallbacks by verizon/level3 public dns servers.
124 root 1.342
125 root 1.339 5.112 Fri Aug 21 13:59:04 CEST 2009
126 root 1.338 - AnyEvent::Handle could cause hard crashes in Net::SSLeay when
127     using starttls with an illegal/uncreatable tls context.
128 root 1.339 - port to broken win32 perls.
129 root 1.338
130 root 1.337 5.111 Sun Aug 16 18:44:36 CEST 2009
131     - perl errornously requires sockaddr_un structures returned by the
132     kernel to have a specific length. work around this bug by padding
133     sockaddr_un structures (found to fail on OS X, as perl only uses
134     the correct code for GNU/Linux, but likely to fail on other
135     OSes as well).
136    
137 root 1.336 5.11 Wed Aug 12 17:49:37 CEST 2009
138 elmex 1.335 - fixed a bug in run_cmd with input from filename.
139 root 1.336 - create a json coder object when none is given in write direction
140     to reduce dependency on JSON.
141 elmex 1.335
142 root 1.334 5.1 Tue Aug 11 03:17:32 CEST 2009
143 root 1.333 - tcp_connect now reports the correct error in $!, not an unrelated
144     one (was broken since 4.91).
145     - AE::Handle did not properly clear rtimeout/wtimeout watchers
146     when retrying a tcp_connect.
147     - new functions: AnyEvent::Util::run_cmd and close_all_fds_except.
148 elmex 1.332 - fixed wrong documentation in AE::Socket.
149    
150 root 1.330 5.01 Mon Aug 10 03:16:32 CEST 2009
151     - last release broke EV child watchers :/.
152    
153 root 1.329 5.0 Sun Aug 9 17:32:09 CEST 2009
154     - officially introduce and document the AE API.
155 root 1.323 - lowering the timeout at runtime did not have immediate effect
156     in AnyEvent::Handle.
157 root 1.324 - AE::Handle now has separate and independent read and write timeout
158     settings.
159 root 1.326 - probe for Guard module when AnyEvent::Util is loaded, not at
160     runtime (Event doesn't like eval "use" from callbacks, and it avoids
161     exporting the probe function).
162 root 1.328 - Impl::IOAsync's io watchers did not use the filehandle emulation
163     code to work around it's watcher limits.
164     - work around IO::Async's problems with overloaded objects.
165     - try to disable wearnings inside IO::Async, it's just too buggy.
166 root 1.327 - do no longer use Event by default, only EV or Perl, Event is too buggy.
167 root 1.329 - hackishly provide fast AE:: interface when EV or Perl is the backend.
168 root 1.325 - inherit VERSION from AnyEvent::VERSION in most modules.
169 root 1.322
170 root 1.321 4.91 Thu Aug 6 15:42:45 CEST 2009
171 root 1.319 - AE::Handle::starttls could get out of sync when the read buffer
172     already contains some TLS handshake.
173 root 1.318 - AE::Handle did not properly free the TLS session, causing bigger
174     memory leaks in Net::SSLeay than expected (reported by toaster).
175 root 1.320 - AE::Socket::tcp_connect will now artificially delay invoking
176     the callback to avoid returning after invoking the callback.
177 root 1.321 - convert many internal watcher uses to AE API.
178 root 1.317
179 root 1.316 4.9 Sat Aug 1 11:07:01 CEST 2009
180 root 1.308 - Glib silently fails when registering a timeout with
181     a negative value, so avoid that.
182 root 1.315 - call condvar callback immediately when it is set
183     after the condition is already signalled.
184 root 1.314 - check rbuf_max condition only after trying to consume
185     data.
186 root 1.305 - normalise signal numbers to names when using the ae's
187     signal handling, but do not document this (yet).
188 root 1.308 - pure perl signal emulation did not properly set nonblocking
189     mode on the signal pipe on win32 (this is unlikely to have caused
190     any issues).
191 root 1.310 - new module: AnyEvent::Debug.
192 root 1.309 - AnyEvent::Strict now checks that a signal was specified
193     by name (not name or number).
194     - reduce memory footprint in typical cases by ~50kb by
195 root 1.308 only compiling signal code when necessary.
196 root 1.313 - add AnyEvent::Handle->rbuf_max.
197 root 1.311 - grab the AE namespace for future new API, implement stubs for
198     said future/alternative API.
199 root 1.315 - new function: AnyEvent::Socket::format_hostport.
200 root 1.305
201 root 1.303 4.881 Tue Jul 28 12:51:53 CEST 2009
202     - work around a bug in local in pre-5.10 perls, causing
203 root 1.304 AnyEvent::Handle to recurse when it should not
204 root 1.351 (analysed by elmex).
205 root 1.303
206 root 1.302 4.88 Tue Jul 28 04:04:37 CEST 2009
207 root 1.301 - re-bless the handle into a dummy package after calling
208     AnyEvent::Handle::destroy, so the user does not need to check
209     for errors after every push_write etc.
210 root 1.302 - do not attempt to run t/02_signals.t on obviously broken
211     platforms.
212 root 1.301
213 root 1.300 4.87 Sun Jul 26 02:06:16 CEST 2009
214 root 1.295 - do not attempt to linger when there is no longer a valid fh.
215 root 1.296 - enforce tls mode to be either accept or connect, do not simply
216     segfault in Net::SSLeay.
217 root 1.298 - AnyEvent::Handle can now call tcp_connect itself (new parameters
218 root 1.299 connect, on_prepare, on_connect and on_connect_error). Updated
219     tutorial accordingly.
220 root 1.297 - add AnyEvent::Impl::Irssi backend.
221 root 1.295
222 root 1.294 4.86 Mon Jul 20 23:52:29 CEST 2009
223     - since the verbose warning is not enough, explicitly document
224     that versions before 1.33 of Net::SSLeay are not secure.
225 root 1.292 - work around signal handling races in Event and (...) Event::Lib.
226 root 1.293 - try to align signal-race timer to full-second boundaries.
227     - work around Tk not liking negative timeouts.
228 root 1.292 - don't complain of different grades of environmental unfriendlyness
229 root 1.302 in IO::Async.
230 root 1.292
231 root 1.290 4.85 Sat Jul 18 06:16:14 CEST 2009
232 root 1.287 - nail the signal race problem in perl once and for all
233     (see $AnyEvent::MAX_SIGNAL_LATENCY).
234     - take advantage of Async::Interrupt if it is available.
235     - load Time::HiRes and Guard modules on demand only.
236     - add optional/recommended modules section to AnyEvent

239     by not using "strict", "warnings" and "overload" modules.
240 root 1.289 - work around buggy windows/openbsd perls and provide EBADMSG
241     and EPROTO ourselves when missing.
242     - improve perl 5.6 compatibility of the core event loop.
243     - made Net::SSLeay version 1.33 a soft requirement.
244 root 1.286
245 root 1.285 4.83 Fri Jul 17 16:56:26 CEST 2009
246 root 1.284 - implement AnyEvent::Socket::getprotobyname.
247 root 1.283 - AnyEvent::CondVar's will now detect recursive blocking
248 root 1.284 waits and will croak, as too many people fall into
249     this trap.
250 root 1.281 - AnyEvent::Handle will now call ->destroy on itself after
251     executing the on_error callback, instead of doing some
252     half-baked internal shutdown, for fatal errors.
253 root 1.282 - clarify on_eof behaviour w.r.t. the read queue and
254     on_read callbacks.
255 root 1.281 - ignore some possible spurious wake-ups in tcp_connect.

257 root 1.278 4.82 Sat Jul 11 00:34:55 CEST 2009
258 root 1.277 - POE and Event backends didn't accept some callable objects as
259     callbacks.
260 root 1.275 - use Config module instead of POSIX module to detect signal names
261     in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
262     module doesn't even have all POSIX signals :/.
263 root 1.276 - use more workarounds around the many refcnt/corruption bugs in
264     Event::Lib.
265     - work around a race condition in perl's select, causing t/03_child.t

268 root 1.274 4.81 Thu Jul 9 10:30:30 CEST 2009
269 root 1.272 - AnyEvent::Handle didn't properly diagnose write errors
270     (it expected -1 from syswrite, how lame... :).
271 root 1.268 - support file descriptors in addition to file handles
272     in AnyEvent->io.
273 root 1.265 - new env variables: PERL_ANYEVENT_RESOLV_CONF,

277 root 1.273 - add a "supported backends" section to the manpage.
278 root 1.270 - added simple io watcher test to testsuite, using a
279     portable_socketpair.

283 root 1.264 4.8 Mon Jul 6 23:45:16 CEST 2009
284 root 1.261 - AnyEvent::DNS did not properly follow CNAME records with
285     uppercase targets.
286 root 1.262 - AnyEvent::DNS would errornously return AAAA records
287     with v4 mapped addresses (a faulty record) as ipv4 addresses,
288     causing AnyEvent::Socket to throw an exception.
289 root 1.260 - added new module AnyEvent::TLS for easier SSL/TLS context
290     creation, with many options including hostname verification,
291     secure default configuration, lots of documentation and,
292     predefined diffie-hellman keys for perfect forward security
293     and much more. get it while it's still fresh!
294     - use AnyEvent::TLS in AnyEvent::Handle for context management.
295 root 1.256 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
296     so AnyEvent::Socket users have smaller memory footprint
297     in the common case.
298 root 1.258 - add AnyEvent::Handle->push_shutdown method.
299     - add an additional error message parameter to AnyEvent::Handle's

302 root 1.257 - make AnyEvent::Handle more robust against early conenction
303     failures (during new), and return C<undef> in that case
304     from the constructor.
305 root 1.259 - AnyEvent::Handle will now try to load only JSON::XS first,
306     then fall back to JSON.
307 root 1.262 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
308     and because it was documented that way.
309 root 1.256
310 root 1.258 4.451 Fri Jul 3 00:28:58 CEST 2009
311     - do not clear rbuf when shutting down an AnyEvent::Handle

313    
314 root 1.255 4.45 Mon Jun 29 22:59:26 CEST 2009
315     - a write error could cause AnyEvent::Handle to create
316     an I/O watcher with an undefined $fh.
317 root 1.251 - special-case mapped ipv4 addresses in both
318     AnyEvent::Socket::format_address and parse_address,
319     to treat them just like ipv4 addresses.
320 root 1.254 - updated and overhauled the AnyEvent::Intro doc.
321 root 1.252 - implement AnyEvent::Socket::format_ipv4/ipv6.
322     - slightly speed up portable_pipe/socketpair.

324 root 1.250
325 root 1.249 4.42 Fri Jun 26 08:32:18 CEST 2009

327 root 1.247 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
328     case it was set to IGNORE, to ensure we can catch child statuses
329     even when the calling env acts stupidly.
330 root 1.248 - updated benchmarks with IO::Async, which performs very well.
331 root 1.247
332 root 1.245 4.412 Wed Jun 24 01:35:57 CEST 2009

345     a signal handler is deleted from the %SIG hash.
346 root 1.237 - use POSIX::_exit in child test, to avoid running
347     destructors.
348     - speed up CHLD handling by relying on SIGCHLD being
349     synchronously delivered, even when we roll our own
350     implementation.
351 root 1.238 - AnyEvent::DNS: add the "dname" resource record name
352     for cosmetic reasons.
353 root 1.235

719 root 1.55 - fix a bug in the pure perl backend that kept watchers alive
720     when multiple watchers were registered for the same fh/poll combo.
721 root 1.54 - add a benchmark section showing AnyEvent overhead and comparing
722     the different event loops with each other.
723 root 1.56 - prefer pure perl over tk when autoprobing, as it's about as fast,
724     but doesn't crash with many watchers.
725 root 1.62 - declare Qt support non-experimental.
726 root 1.56 - clarify the confusing section about the file descriptor being
727     kept alive.
728     - document the race between loading of an event module and
729     child processes exiting.
730 root 1.53 - support POE as "backend" (with some caveats, POE is not generic
731 root 1.54 enough, and darn slow).
732 root 1.53 - support Wx and Prima through POE.
733 root 1.60 - optimise perl backend to use 20% less memory and take advantage
734 root 1.62 of typical timeout behaviour. It can now compete with
735 root 1.60 select/poll-based C event loops in most cases (it is usually
736     faster than Event and Glib :).
737 root 1.59 - roughly cut EV memory use in half and increase its speed by 30%,
738 root 1.62 by removing undocumented functionality. Did something similar
739     to other event loops where possible.
740 root 1.53
741 root 1.50 3.2 Thu Apr 24 10:10:40 CEST 2008
742 root 1.51 - do not die when anyevent watchers are destroyed while running callbacks
743     in the pureperl backend (could only happen when two watchers are registered
744     for the same fh/poll combo).
745     - support autoloading for child watchers, was broken in all versions.
746 root 1.47 - implement PERL_ANYEVENT_MODEL env variable.
747 root 1.49 - (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
748     - (experimental) implement interface to the Qt module (cannot be autoprobed).
749 root 1.52 - this release is IO:AnyEvent-proof.
750 root 1.47
751 root 1.46 3.12 Tue Apr 22 07:11:46 CEST 2008
752     - reinstate AUTHOR section that got lost somehow.
753     - do not hang in the testsuite with badly broken perls (activestate,
754     strawberry...), but instead diagnose the problem and continue.
755     - use INT instead of CHLD in an attempt to support broken windows perls
756     better (this decreases the test quality, unfortunately).
757     - do not send the signal to the process group
758     (no problem for CHLD, bad for INT :).
759    
760 root 1.45 3.11 Sat Apr 19 06:57:31 CEST 2008
761     - major documentation rework.
762     - document the fact that child watchers only watch for zombies.
763     - fix the child watcher example.
764    
765 root 1.43 3.1 Wed Apr 16 17:09:01 CEST 2008
766 root 1.40 - work around recurring bugs in Tk by dup'ing filehandles, the
767 root 1.43 only method with good success chances on Tk (the bugs apparently
768     don't get fixed anytime soon).
769 root 1.42 - lift the restriction of only one watcher per fh direction
770     (as the Tk bug workaround also lifts it and only Tk imposed
771     such strong limits).
772 root 1.41 - changed probe order to prefer coro adaptors.
773     - explain why recursion into the event loop is not supported
774     unless the backend supports it (only Coro::EV does without
775     any restrictions...).
776     - add simple manpages for all backend modules.
777 root 1.40
778 root 1.39 3.0 Mon Apr 7 21:30:23 CEST 2008
779 root 1.38 - Coro::Signal changed semantics, roll our own, also cleaning
780     up the Coro implementation in general.
781     - rename Coro backend to CoroEvent.
782     - add some decision helping paragraph to the manpage that should
783 root 1.44 help people to decide whether AnyEvent is the right thing for them.
784 root 1.38
785 root 1.37 2.9 Mon Jan 28 13:31:54 CET 2008
786     - update for EV 3.0 API changes.
787    
788 root 1.36 2.8 Sun Nov 25 15:06:03 CET 2007
789     - waitpid can validly return 0. accept this fact of life
790     instead of reporting it to any watchers.
791    
792 root 1.35 2.7 Fri Nov 23 11:41:14 CET 2007
793 root 1.34 - force use of AnyEvent::Impl::Perl in testsuite, there is
794     too much breakage outside AnyEvent.
795 root 1.35 - deliver signals synchronously in AnyEvent::Impl::Perl
796     or any other event loop that relies on AnyEvents child
797     watcher emulation. *Could* help with hanging testsuite
798     (except when Event or EV are installed).
799 root 1.34
800 root 1.33 2.6 Fri Nov 9 20:36:35 CET 2007
801 root 1.32 - fix bug in testsuite.
802     - move EV adaptor modules to AnyEvent.
803     - add Coro+EV adaptor module.
804 root 1.26
805 root 1.31 2.55 Tue Nov 6 17:41:32 CET 2007
806 root 1.27 - add EV to the list of supported event models.
807 root 1.30 - do not auto-reset pid watchers, pass pid and status to them.
808 root 1.29 - allow a pid of zero to watch for all children in child watchers.
809 root 1.27
810 root 1.25 2.54 Wed Jul 18 17:36:23 CEST 2007
811     - work around a perl bug that results in
812     BEGIN not safe after errors--compilation aborted without
813     any discernible reason or error message by once
814     again not use'ing strict.
815    
816 root 1.24 2.53 Sun Jul 8 10:51:53 CEST 2007
817     - make Glib interface work again (spotted by elmex).
818    
819 root 1.22 2.52 Wed Mar 7 18:36:16 CET 2007
820     - child watchers stopped working permanently when
821 root 1.23 all current child watchers were destroyed.
822 root 1.22
823 root 1.21 2.51 Mon Dec 11 21:33:24 CET 2006
824     - work around bugs in perl where eval "require Module" returns
825     true even if the module couldn't be loaded :/.
826    
827 root 1.20 2.5 Mon Dec 11 02:15:28 CET 2006
828 root 1.19 - avoid $AUTOLOAD because many perls corrupt it.
829 root 1.20 - AnyEvent::detect forces autodetection.
830     - implement signal watchers (experimental)
831     (Tk does not support async signals (<= 804.027 at least),
832     so they might get delayed indefinitely on Tk).
833     - implement child watchers (experimental).
834     - moved default condvar implementation into base module, simplifying
835     most implementation modules.
836 root 1.14
837 root 1.18 2.1 Fri Nov 24 15:50:48 CET 2006
838 root 1.16 - better docs.
839     - simple testsuite.
840 root 1.17 - added AnyEvent->one_event method for special purposes.
841 root 1.16
842 root 1.15 2.0 Wed Nov 1 02:21:30 CET 2006
843 root 1.13 - INCOMPATIBLE CHANGE: poll can now either be "r" or "w" but not both.
844     - INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
845     - EXPERIMENTAL:
846     new pure-perl model added, AnyEvent now always finds a suitable
847     event model.
848 root 1.12 - improved documentation.
849     - reduced cpu overhead.
850    
851 root 1.11 1.02 Fri Jan 13 14:15:40 CET 2006
852     - add COPYING to clarify license.
853    
854 root 1.10 1.01 Sun Jan 8 05:48:09 CET 2006
855     - correctly cancel Event timers, avoid memory leaks.
856    
857 root 1.9 1.0 Sun Jan 8 05:40:58 CET 2006
858 root 1.8 - allow third-party interfaces to be added at runtime.
859     - fix version number.
860    
861 root 1.7 0.9 Fri Dec 30 02:25:41 CET 2005
862 root 1.6 - fixed errors in the documentation.
863 root 1.7 - going back to using $VERSION as "load check",
864     as suggested by Jörn Reder. Let's see why I stopped using
865     this method.
866     - add 'hup' to the list of events to receive for glib
867     and generate 'rw' events for it, as some versions of
868     glib seem to require this, while this breaks other
869     (older) versions of glib.
870     - implemented PERL_ANYEVENT_VERBOSE env variable.
871 root 1.6
872 root 1.5 0.3 Sun Dec 4 10:43:33 CET 2005
873     - no changes to the code.
874     - fixed documentation.
875     - clarified some corner cases.
876     - vastly improved documentation with a long example.
877    
878 root 1.3 0.2 Thu Dec 1 22:18:49 CET 2005
879 root 1.44 - check whether a valid method was called, to avoid endless loops.
880 root 1.4 - move condvars into their own class (cleaner, safer).
881     - don't die when some modules are not available.
882     - Tk is too broken to allow for words. Will work once Tk works.
883 root 1.3
884 root 1.2 0.1 Thu Dec 1 19:44:57 CET 2005
885     - spiced up and cleaned up for release.
886    
887 root 1.1 0.01 Tue Sep 21 18:12:09 CEST 2004
888     - original version; copied from Convert::Scalar.
