1 root 1.1 Revision history for Perl extension AnyEvent.
2    
3 root 1.392 TODO: docs signal for condvar
4    
5 root 1.396 TODO: FIX PIPE CHECK! explicitly ceck for datagram sockets and files
6 root 1.395 - simplified and reworked the "OTHER MODULES" section.
7     - explicitly check for non-stream sockets in AE::Handle, too many
8     clueless people fell into the trap of this somehow working
9     (see the horrible AE::Handle::UDP for a good example...).
10    
11 root 1.394 5.261 Wed Apr 28 16:13:36 CEST 2010
12 root 1.393 - AF_INET6 was not properly used from Socket6 during configuration
13     time (found by Andy Grundman).
14    
15 root 1.392 5.26 Mon Apr 12 04:49:35 CEST 2010
16 root 1.389 - don't generate spurious readyness notifications when select
17     returns EINTR in the pure perl backend (analysed and testcase
18     by Bas Denissen).
19 root 1.391 - give same examples in SYNOPSIS sections of AnyEvent and AE.
20 root 1.390 - provider faster implementations for AE::time/now/now_update for
21     EV and Perl backends.
22     - provide faster AE::cv and AE::time implementations for all
23     backends.
24     - no longer support lower/mixed-case signal names (this was
25     never documented nor universally supported).
26     - some more memory µ-optimisations, and somewhat less messy
27     code to cope with both AnyEvent and AE APIs.
28 root 1.389
29 root 1.386 5.251 Sat Mar 13 00:58:21 CET 2010
30 root 1.387 - make test failed if it was run before make install on perl <=
31     5.8.8, and older versions of perl make our live very difficult,
32     so write constants.pl during Makefile.PL time.
33 root 1.386
34 root 1.384 5.25 Sat Mar 13 00:23:14 CET 2010
35 root 1.383 - fix a race condition in AnyEvent::Handle that would cause
36     a "bio_read: unsupported method" error (in _another_
37     ssl connection) after user code threw an exception.
38 root 1.385 - added AnyEvent::Handle->destroyed method.
39 root 1.376 - speed up AnyEvent::Socket::format_address and ::format_ipv6.
40 root 1.378 - the AnyEvent::Util::fh_nonblocking function worked only
41     by lucky accident on win32.
42 root 1.377 - smaller and faster AnyEvent::Util::fh_nonblocking.
43 root 1.379 - when the (required!) Time::HiRes module is missing, AnyEvent
44     did not fall back to built-in time properly.
45 root 1.381 - do not load Fcntl at runtime, saving memory and loading time.
46     - precompile a number of constants and use them instead of runtime
47     detection and eval.
48     - free detection code after detection and similar memory optimisations.
49 root 1.382 - Perl backend timer interval best effort drift has been improved
50 root 1.388 (same algorithm as EV).
51 root 1.385 - update unicode idna mapping table.
52 root 1.376
53 root 1.375 5.24 Tue Jan 5 11:39:43 CET 2010
54     - cygwin never reports errors from failed connects. 1.5 just gives
55     you continous readyness and EAGAIN, 1.7 is even more broken and
56     just hangs. work around both issues in a cygwin-specific hack.
57 root 1.374 - improve idle watcher documentation slightly.
58    
59 root 1.373 5.23 Sun Dec 20 23:48:00 CET 2009
60 root 1.372 - support IDNs in resolve_sockaddr, and therefore in tcp_connect.
61 root 1.373 - implement punycode_encode/decode, idn_nameprep,
62     idn_to_ascii and idn_to_unicode operations in AnyEvent::Util.
63 root 1.366 - provide $AE::VERSION.
64 root 1.367 - removed traces of "no strict 'refs'".
65 root 1.366
66 root 1.365 5.22 Sat Dec 5 03:51:13 CET 2009
67 root 1.358 - downgrade-or-fail in AnyEvent::Handle::push_write, to
68     diagnose encoding failures earlier and more succinctly.
69 root 1.359 (this works around bugs in perl, throwing away encoding info
70     when passing scalar data to extensions).
71 root 1.360 - add more examples to AnyEvent::Socket manpage.
72 root 1.361 - upgrade internal warning set to the same as common::sense 2.03.
73 root 1.362 - use pack "n/a*" for pre-5.8.9 perl compatibility in AnyEvent::DNS
74     (John Beppu).
75 root 1.364 - AnyEvent::Socket::inet_aton now properly supports ipv6, as documented.
76 root 1.363 - add google public dns servers to fallback server set and make sure
77     we load-balance properly between the three sets. also add all
78     fallback dns servers, not just a random one, to each dns config.
79 root 1.358
80 root 1.357 5.21 Thu Nov 19 02:48:47 CET 2009
81 root 1.356 - fix a problem where socket constants were called with parameters
82 root 1.355 (spotted by David Friedland).
83 root 1.356 - fork_call never use'd POSIX (reported by Daisuke Maki).
84 root 1.355 - improve perl 5.6 compatibility further (but it still won't work
85     unless you rip out everything but the core).
86 root 1.357 - prefer Net::DNS::Resolver over ipconfig, if installed, on win32.
87     uses 10MB of RAM, but doesn't open a console window. *sigh*.
88 root 1.355
89 root 1.354 5.202 Wed Oct 14 22:35:44 CEST 2009
90     - AnyEvent::DNS would unexpectedly clobber $_ under windows
91     (analysed by Matthias Waldorf).
92 root 1.353 - AnyEvent::Handle::run_cmd can now pass the PID of the
93     newly-created process, which is much less useful than it might
94     sound (based on patch by Yann Kerherve).
95    
96 root 1.352 5.201 Tue Sep 29 12:09:25 CEST 2009
97 root 1.350 - AnyEvent:Handle::on_starttls/on_stoptls methods were broken
98     (reported by Torsten Foertsch).
99 root 1.351 - common::sense 2.0 could cause tcp_server to throw an exception
100     (analysed by elmex).
101 root 1.350
102 root 1.349 5.2 Mon Sep 14 07:04:49 CEST 2009
103 root 1.347 - INCOMPATIBLE CHANGE: do no longer support register_read_type
104     and register_write_type in AnyEvent::Handle, instead support
105     package names (the facility was mostly abused).
106 root 1.349 - implement "packagename-as-read/write type" support in
107     AnyEvent::Handle.
108 root 1.345 - AnyEvent::Handle: new options "keepalive" and "oobinline".
109 root 1.346 - oobinline set by default to avoid security issues.
110 root 1.349 - the pure-perl event loop backend wrongly detected times() fallback
111     support (spotted by Pavel Boldin).
112 root 1.345
113 root 1.344 5.12 Tue Sep 1 20:26:50 CEST 2009
114 root 1.343 - be more lenient when parsing resolv.conf files, as some people
115     use hashmarks as comment indicator inside directives (reported
116     by Michael S. Fischer).
117     - use same set of warnings as common::sense 2.0.
118 root 1.342 - fix a potential 32 bit overflow issue due to perl having problems
119     with large hex constants in the Perl backend.
120     - do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS
121     by default.

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

240     by not using "strict", "warnings" and "overload" modules.
241 root 1.289 - work around buggy windows/openbsd perls and provide EBADMSG
242     and EPROTO ourselves when missing.
243     - improve perl 5.6 compatibility of the core event loop.
244     - made Net::SSLeay version 1.33 a soft requirement.
245 root 1.286
246 root 1.285 4.83 Fri Jul 17 16:56:26 CEST 2009
247 root 1.284 - implement AnyEvent::Socket::getprotobyname.
248 root 1.283 - AnyEvent::CondVar's will now detect recursive blocking
249 root 1.284 waits and will croak, as too many people fall into
250     this trap.
251 root 1.281 - AnyEvent::Handle will now call ->destroy on itself after
252     executing the on_error callback, instead of doing some
253     half-baked internal shutdown, for fatal errors.
254 root 1.282 - clarify on_eof behaviour w.r.t. the read queue and
255     on_read callbacks.
256 root 1.281 - ignore some possible spurious wake-ups in tcp_connect.
257 root 1.279
258 root 1.278 4.82 Sat Jul 11 00:34:55 CEST 2009
259 root 1.277 - POE and Event backends didn't accept some callable objects as
260     callbacks.
261 root 1.275 - use Config module instead of POSIX module to detect signal names
262     in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
263     module doesn't even have all POSIX signals :/.
264 root 1.276 - use more workarounds around the many refcnt/corruption bugs in
265     Event::Lib.
266     - work around a race condition in perl's select, causing t/03_child.t

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

279 root 1.270 - added simple io watcher test to testsuite, using a
280     portable_socketpair.

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

303 root 1.257 - make AnyEvent::Handle more robust against early conenction
304     failures (during new), and return C<undef> in that case
305     from the constructor.
306 root 1.259 - AnyEvent::Handle will now try to load only JSON::XS first,
307     then fall back to JSON.
308 root 1.262 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
309     and because it was documented that way.

312     - do not clear rbuf when shutting down an AnyEvent::Handle

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

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

346     a signal handler is deleted from the %SIG hash.
347 root 1.237 - use POSIX::_exit in child test, to avoid running
348     destructors.
349     - speed up CHLD handling by relying on SIGCHLD being
350     synchronously delivered, even when we roll our own
351     implementation.
352 root 1.238 - AnyEvent::DNS: add the "dname" resource record name
353     for cosmetic reasons.
354 root 1.235
355 root 1.234 4.4 Sun Apr 26 20:12:33 CEST 2009

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