96.01
10 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include
11 the TTL as fourth element - this affects ->resolve, ->request
12 and ->dns_unpack indirectly. Convenience functions such as
13 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is
14 AnyEvent::Socket.
15 - INCOMPATIBLE CHANGE: backend authors now should not implement
16 one_event or loop, but instead the AnyEvent::CondVar::_wait and _poll
17 methods.
18 - INCOMPATIBLE CHANGE: verbosity levels have been redefined, see
19 AnyEvent (PERL_ANYEVENT_VERBOSE) and AnyEvent::Log for details.
20 - DEPRECIATION: please change
21 "use AnyEvent::Impl::Perl" to "use AnyEvent::Loop" and
22 "AnyEvent::Impl::Perl::loop" to "AnyEvent::Loop::run"
23 in your programs, for future compatibility.
24 - *blush* idle watcher emulation was borked.
25 - AnyEvent::Strict now checks the AE::xxx functions as well.
26 - querying too long domain names would barf deep inside AnyEvent::DNS - since
27 this is hard to avoid for applications, AnyEvent:.DNS::request now checks for
28 for too long domain names explicitly and passes an undef to the callback
29 instead (reported by James Bromberger).
30 - make AnyEvent::Util more robust against EINTR (analyzed by Andrew Suffield).
31 - new functions: AnyEvent::postpone, AnyEvent::log.
32 - new module: AnyEvent::Log, for simple logging needs.
33 - new env variable, PERL_ANYEVENT_DEBUG_SHELL, to automatically start
34 a debug shell.
35 - new env variable, PERL_ANYEVENT_DEBUG_WRAP, to automatically enable
36 watcher instrumentation/wrapping (see AnyEvent::Debug::wrap).
37 - lots of new AnyEvent::Debug functionality.
38 - AnyEvent::Strict now checks for modifications $_ by the callback
39 (by setting it to readonly while executing the callback, if possible).
40 - IO::Async sometimes cancels the wrong timer when you call cancel_timer.
41 Invest extra overhead to work around this peculiar behaviour.
42 - split the pure perl backend into a loop module and an impl
43 module (AnyEvent::Loop and AnyEvent::Impl::Perl).
44 - some read types (regex, netstring, json, storable) could
45 errornously keep an AE::Handle object alive on their own
46 (reported by Mohammad Toossi).
47 - add more workarounds around child watcher bugs in IO::Async
48 and (newly introduced) in POE.
49 - use glib child watchers and try to work around its limitations,
50 if possible (based on a patch by Kevin Ryde).
51 - add support for FLTK (fltk2), via AnyEvent::Impl::FLTK2.
52 - many read types in AnyEvent::Handle would malfunction during
53 transitions to TLS because of a "delete $self->{rbuf}".
54 (reported by Gerald Galster).
55 - improve condvar blocking wait performance (probably only noticable
56 with faster backends), also make it easier for event loops that
57 do not support blocking waits.
58 - PERL_ANYEVENT_MODEL now also allows full module names, although
59 the usefulness of this feature is not yet clear.
60 - add tests for all supported event loops, conditional on PERL_ANYEVENT_LOOP_TESTS.
61 - add t/80_ssltext.t.
62 - no longer use AUTOLOAD for the initial loading (for no very good reason).
63 - tcp_server now tries to unlink unix domain sockets when it gets destroyed.
64 - do not run event loop detection multiple times when programs call their cached
65 copies of AnyEvent::detect.
66 - parse_hostport now accepts absolute paths als unix domain sockets.
67 - add Task::Weaken as dependency (as recommends only at this time).
68
696.0 (not officially released, but was on CPAN for about 15 minutes :/)
70
715.34 Thu May 12 09:59:41 CEST 2011
72 - AE::TLS didn't support both cert_file and key at the same time,
73 due to some copy&paste bug (reported and analyzed by vti).
74 - improve AE::Handle timeout documentation slightly.
75
765.33 Mon Feb 7 21:51:41 CET 2011
77 - never appeared on CPAN, for unknown reasons.
78 - AnyEvent::Handle on_connect_error - do not try to destroy a handle
79 object when it's already gone (analyzed by Ryan Bullock).
80 - update idna algorithm(s) to UTS#46 version 6.0.0.
81 - preserve trailing dot in idn_to_ascii - testsuite says to preserve,
82 uts46 says it's an error, and testsuite makes more sense.
83 - remove leading dots in idn_to_ascii - testsuite says to remove,
84 uts46 says it's an error, and testsuite makes more sense.
85 - fixed a bug in idn ignored character processing.
86 - passes the uts46 6.0.0 testsuite except for three cases which
87 apparently are bugs in the testsuite itself.
88 - passes the uts46 6.0.1 testsuite except for eleven cases which
89 apparently are bugs in the testsuite itself.
90
915.31 Sun Jan 23 11:49:19 CET 2011
92 - work around a POE bug where POE would first poll for new events and
93 invoke handlers BEFORE handling the message queue.
94 - fix parsing of "domain" statement in resolv.conf (Johannes Plunien).
95 - stop_read now does just that in TLS mode. see its
96 documentation for caveats.
97 - update to common::sense 3.4 warning set (some warnings in perl impose
98 an arbitrary 32kb limit on regex matches, which affects
99 AnyEvent::Handle).
100 - AE::Handle had a broken rbuf_max method and missing wbuf_max method.
101 - new experimental AE::Handle::resettls method.
102
1035.3 Fri Dec 31 05:48:13 CET 2010
104 - major IOAsync patch by Paul Evans - 0.33 is required, as the major
105 issues with IO::Async have been solved in that version, including
106 the availabilty of a default loop!
107 - implement new wbuf_max parameter for AnyEvent::Handle.
108 - added Cocoa::EventLoop backend by Daisuke Murase.
109 - the default testsuite now honors PERL_ANYEVENT_MODEL (Paul Evans).
110 - clarify handle on_prepare documentation.
111 - set CLOEXEC flag on parent-side fd's in AnyEvent::Util::run_cmd,
112 to avoid leaking them to any child processes.
113 - try to force files into the arch-dependend lib directory, for the
114 half-"turly obsessive compulsive person"(s) that depend on it.
115
1165.29 Sun Dec 5 10:49:21 CET 2010
117 - convert EV backend to EV 4.00 API (so better upgrade EV too).
118 - AE::Handle: implement dynamic read_size adjustment, add
119 max_read_size parameter, reduce default read_size to 2048.
120 - add some FAQ entries for servers and/or on_eof vs. on_error.
121 - work around OS bugs (cygwin again) when lingering in AE::Handle.
122 - reduce memory usage slightly when connect was used in AE::Handle.
123 - wrok around more segfaults in Tk.
124 - document tls_ctx => undef as valid.
125 - detect WNOHANG value at compiletime.
126 - include some probably linux-only support for building AnyEvent
127 as part of the perl core.
128 - improve compatibility of t/08_idna.t to perl 5.8.
129 - make AnyEvent::Strict truly optional (in case somebody builds a
130 minimal perl...).
131
1325.28 Wed Oct 13 04:14:23 CEST 2010
133 - due to a glitch, AnyEvent's internal getprotobyname wasn't
134 actually used in tcp_server.
135 - implement AnyEvent::CondVar->new method, which was documented but
136 missing.
137 - support autoloading of read types in unshift_read.
138 - AnyEvent::Strict: do the test for invalid fh arguments differently,
139 resulting in more informative error messages.
140 - new AnyEvent::FAQ manpage.
141 - clarify that you can actually call push_read etc. in on_read.
142 - put keys and certs in /tmp, not into the current directory,
143 and document this in the SECURITY CONSIDERATIONS sections
144 of AnyEvent::TLS.
145 - support ";" as resolv.conf comment character in AnyEvent::DNS, as
146 requested by Ron Isaacson.
147 - document $AnyEvent::DNS::RESOLVER variable.
148 - incorporated major typo patches by Abhijit Menon-Sen.
149 - AnyEvent::Handle now croaks when negative timeouts are passed.
150 - add a shitload of TCP_xxx sockopt name constants to AnyEvent::Util,
151 undocumented, but who knows when they might come in handy.
152
1535.271 Tue Jun 8 12:05:46 CEST 2010
154 - backport to perl 5.8.x.
155
1565.27 Sun Jun 6 12:12:05 CEST 2010
157 - postpone differently in AnyEvent::Socket now, as
158 when not, canceling the connection attempt might fail
159 (found by Felix Antonius Wilhelm Ostmann).
160 - explicitly check for non-stream sockets in AE::Handle, too many
161 clueless people fell into the trap of this somehow working.
162 - simplified and reworked the "OTHER MODULES" section.
163 - better/more condvar examples.
164
1655.261 Wed Apr 28 16:13:36 CEST 2010
166 - AF_INET6 was not properly used from Socket6 during configuration
167 time (found by Andy Grundman).
168
1695.26 Mon Apr 12 04:49:35 CEST 2010
170 - don't generate spurious readyness notifications when select
171 returns EINTR in the pure perl backend (analysed and testcase
172 by Bas Denissen).
173 - give same examples in SYNOPSIS sections of AnyEvent and AE.
174 - provider faster implementations for AE::time/now/now_update for
175 EV and Perl backends.
176 - provide faster AE::cv and AE::time implementations for all
177 backends.
178 - no longer support lower/mixed-case signal names (this was
179 never documented nor universally supported).
180 - some more memory ยต-optimisations, and somewhat less messy
181 code to cope with both AnyEvent and AE APIs.
182
1835.251 Sat Mar 13 00:58:21 CET 2010
184 - make test failed if it was run before make install on perl <=
185 5.8.8, and older versions of perl make our live very difficult,
186 so write constants.pl during Makefile.PL time.
187
1885.25 Sat Mar 13 00:23:14 CET 2010
189 - fix a race condition in AnyEvent::Handle that would cause
190 a "bio_read: unsupported method" error (in _another_
191 ssl connection) after user code threw an exception.
192 - added AnyEvent::Handle->destroyed method.
193 - speed up AnyEvent::Socket::format_address and ::format_ipv6.
194 - the AnyEvent::Util::fh_nonblocking function worked only
195 by lucky accident on win32.
196 - smaller and faster AnyEvent::Util::fh_nonblocking.
197 - when the (required!) Time::HiRes module is missing, AnyEvent
198 did not fall back to built-in time properly.
199 - do not load Fcntl at runtime, saving memory and loading time.
200 - precompile a number of constants and use them instead of runtime
201 detection and eval.
202 - free detection code after detection and similar memory optimisations.
203 - Perl backend timer interval best effort drift has been improved
204 (same algorithm as EV).
205 - update unicode idna mapping table.
206
2075.24 Tue Jan 5 11:39:43 CET 2010
208 - cygwin never reports errors from failed connects. 1.5 just gives
209 you continous readyness and EAGAIN, 1.7 is even more broken and
210 just hangs. work around both issues in a cygwin-specific hack.
211 - improve idle watcher documentation slightly.
212
2135.23 Sun Dec 20 23:48:00 CET 2009
214 - support IDNs in resolve_sockaddr, and therefore in tcp_connect.
215 - implement punycode_encode/decode, idn_nameprep,
216 idn_to_ascii and idn_to_unicode operations in AnyEvent::Util.
217 - provide $AE::VERSION.
218 - removed traces of "no strict 'refs'".
219
2205.22 Sat Dec 5 03:51:13 CET 2009
221 - downgrade-or-fail in AnyEvent::Handle::push_write, to
222 diagnose encoding failures earlier and more succinctly.
223 (this works around bugs in perl, throwing away encoding info
224 when passing scalar data to extensions).
225 - add more examples to AnyEvent::Socket manpage.
226 - upgrade internal warning set to the same as common::sense 2.03.
227 - use pack "n/a*" for pre-5.8.9 perl compatibility in AnyEvent::DNS
228 (John Beppu).
229 - AnyEvent::Socket::inet_aton now properly supports ipv6, as documented.
230 - add google public dns servers to fallback server set and make sure
231 we load-balance properly between the three sets. also add all
232 fallback dns servers, not just a random one, to each dns config.
233
2345.21 Thu Nov 19 02:48:47 CET 2009
235 - fix a problem where socket constants were called with parameters
236 (spotted by David Friedland).
237 - fork_call never use'd POSIX (reported by Daisuke Maki).
238 - improve perl 5.6 compatibility further (but it still won't work
239 unless you rip out everything but the core).
240 - prefer Net::DNS::Resolver over ipconfig, if installed, on win32.
241 uses 10MB of RAM, but doesn't open a console window. *sigh*.
242
2435.202 Wed Oct 14 22:35:44 CEST 2009
244 - AnyEvent::DNS would unexpectedly clobber $_ under windows
245 (analysed by Matthias Waldorf).
246 - AnyEvent::Handle::run_cmd can now pass the PID of the
247 newly-created process, which is much less useful than it might
248 sound (based on patch by Yann Kerherve).
249
2505.201 Tue Sep 29 12:09:25 CEST 2009
251 - AnyEvent:Handle::on_starttls/on_stoptls methods were broken
252 (reported by Torsten Foertsch).
253 - common::sense 2.0 could cause tcp_server to throw an exception
254 (analysed by elmex).
255
2565.2 Mon Sep 14 07:04:49 CEST 2009
257 - INCOMPATIBLE CHANGE: do no longer support register_read_type
258 and register_write_type in AnyEvent::Handle, instead support
259 package names (the facility was mostly abused).
260 - implement "packagename-as-read/write type" support in
261 AnyEvent::Handle.
262 - AnyEvent::Handle: new options "keepalive" and "oobinline".
263 - oobinline set by default to avoid security issues.
264 - the pure-perl event loop backend wrongly detected times() fallback
265 support (spotted by Pavel Boldin).
266
2675.12 Tue Sep 1 20:26:50 CEST 2009
268 - be more lenient when parsing resolv.conf files, as some people
269 use hashmarks as comment indicator inside directives (reported
270 by Michael S. Fischer).
271 - use same set of warnings as common::sense 2.0.
272 - fix a potential 32 bit overflow issue due to perl having problems
273 with large hex constants in the Perl backend.
274 - do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS
275 by default.
276 - fix some prototypes.
277 - (optionally) require Async::Interrupt 1.02.
278 - replace opendns fallbacks by verizon/level3 public dns servers.
279
2805.112 Fri Aug 21 13:59:04 CEST 2009
281 - AnyEvent::Handle could cause hard crashes in Net::SSLeay when
282 using starttls with an illegal/uncreatable tls context.
283 - port to broken win32 perls.
284
2855.111 Sun Aug 16 18:44:36 CEST 2009
286 - perl errornously requires sockaddr_un structures returned by the
287 kernel to have a specific length. work around this bug by padding
288 sockaddr_un structures (found to fail on OS X, as perl only uses
289 the correct code for GNU/Linux, but likely to fail on other
290 OSes as well).
291
2925.11 Wed Aug 12 17:49:37 CEST 2009
293 - fixed a bug in run_cmd with input from filename.
294 - create a json coder object when none is given in write direction
295 to reduce dependency on JSON.
296
2975.1 Tue Aug 11 03:17:32 CEST 2009
298 - tcp_connect now reports the correct error in $!, not an unrelated
299 one (was broken since 4.91).
300 - AE::Handle did not properly clear rtimeout/wtimeout watchers
301 when retrying a tcp_connect.
302 - new functions: AnyEvent::Util::run_cmd and close_all_fds_except.
303 - fixed wrong documentation in AE::Socket.
304
3055.01 Mon Aug 10 03:16:32 CEST 2009
306 - last release broke EV child watchers :/.
307
3085.0 Sun Aug 9 17:32:09 CEST 2009
309 - officially introduce and document the AE API.
310 - lowering the timeout at runtime did not have immediate effect
311 in AnyEvent::Handle.
312 - AE::Handle now has separate and independent read and write timeout
313 settings.
314 - probe for Guard module when AnyEvent::Util is loaded, not at
315 runtime (Event doesn't like eval "use" from callbacks, and it avoids
316 exporting the probe function).
317 - Impl::IOAsync's io watchers did not use the filehandle emulation
318 code to work around it's watcher limits.
319 - work around IO::Async's problems with overloaded objects.
320 - try to disable wearnings inside IO::Async, it's just too buggy.
321 - do no longer use Event by default, only EV or Perl, Event is too buggy.
322 - hackishly provide fast AE:: interface when EV or Perl is the backend.
323 - inherit VERSION from AnyEvent::VERSION in most modules.
324
3254.91 Thu Aug 6 15:42:45 CEST 2009
326 - AE::Handle::starttls could get out of sync when the read buffer
327 already contains some TLS handshake.
328 - AE::Handle did not properly free the TLS session, causing bigger
329 memory leaks in Net::SSLeay than expected (reported by toaster).
330 - AE::Socket::tcp_connect will now artificially delay invoking
331 the callback to avoid returning after invoking the callback.
332 - convert many internal watcher uses to AE API.
333
3344.9 Sat Aug 1 11:07:01 CEST 2009
335 - Glib silently fails when registering a timeout with
336 a negative value, so avoid that.
337 - call condvar callback immediately when it is set
338 after the condition is already signalled.
339 - check rbuf_max condition only after trying to consume
340 data.
341 - normalise signal numbers to names when using the ae's
342 signal handling, but do not document this (yet).
343 - pure perl signal emulation did not properly set nonblocking
344 mode on the signal pipe on win32 (this is unlikely to have caused
345 any issues).
346 - new module: AnyEvent::Debug.
347 - AnyEvent::Strict now checks that a signal was specified
348 by name (not name or number).
349 - reduce memory footprint in typical cases by ~50kb by
350 only compiling signal code when necessary.
351 - add AnyEvent::Handle->rbuf_max.
352 - grab the AE namespace for future new API, implement stubs for
353 said future/alternative API.
354 - new function: AnyEvent::Socket::format_hostport.
355
3564.881 Tue Jul 28 12:51:53 CEST 2009
357 - work around a bug in local in pre-5.10 perls, causing
358 AnyEvent::Handle to recurse when it should not
359 (analysed by elmex).
360
3614.88 Tue Jul 28 04:04:37 CEST 2009
362 - re-bless the handle into a dummy package after calling
363 AnyEvent::Handle::destroy, so the user does not need to check
364 for errors after every push_write etc.
365 - do not attempt to run t/02_signals.t on obviously broken
366 platforms.
367
3684.87 Sun Jul 26 02:06:16 CEST 2009
369 - do not attempt to linger when there is no longer a valid fh.
370 - enforce tls mode to be either accept or connect, do not simply
371 segfault in Net::SSLeay.
372 - AnyEvent::Handle can now call tcp_connect itself (new parameters
373 connect, on_prepare, on_connect and on_connect_error). Updated
374 tutorial accordingly.
375 - add AnyEvent::Impl::Irssi backend.
376
3774.86 Mon Jul 20 23:52:29 CEST 2009
378 - since the verbose warning is not enough, explicitly document
379 that versions before 1.33 of Net::SSLeay are not secure.
380 - work around signal handling races in Event and (...) Event::Lib.
381 - try to align signal-race timer to full-second boundaries.
382 - work around Tk not liking negative timeouts.
383 - don't complain of different grades of environmental unfriendlyness
384 in IO::Async.
385
3864.85 Sat Jul 18 06:16:14 CEST 2009
387 - nail the signal race problem in perl once and for all
388 (see $AnyEvent::MAX_SIGNAL_LATENCY).
389 - take advantage of Async::Interrupt if it is available.
390 - load Time::HiRes and Guard modules on demand only.
391 - add optional/recommended modules section to AnyEvent
392 documentation.
393 - reduce memory usage considerably (and reduce startup penalty)
394 by not using "strict", "warnings" and "overload" modules.
395 - work around buggy windows/openbsd perls and provide EBADMSG
396 and EPROTO ourselves when missing.
397 - improve perl 5.6 compatibility of the core event loop.
398 - made Net::SSLeay version 1.33 a soft requirement.
399
4004.83 Fri Jul 17 16:56:26 CEST 2009
401 - implement AnyEvent::Socket::getprotobyname.
402 - AnyEvent::CondVar's will now detect recursive blocking
403 waits and will croak, as too many people fall into
404 this trap.
405 - AnyEvent::Handle will now call ->destroy on itself after
406 executing the on_error callback, instead of doing some
407 half-baked internal shutdown, for fatal errors.
408 - clarify on_eof behaviour w.r.t. the read queue and
409 on_read callbacks.
410 - ignore some possible spurious wake-ups in tcp_connect.
411
4124.82 Sat Jul 11 00:34:55 CEST 2009
3 - POE and Event backends didn't accept some callable objects as 413 - POE and Event backends didn't accept some callable objects as
4 callbacks. 414 callbacks.
5 - use Config module instead of POSIX module to detect signal names 415 - use Config module instead of POSIX module to detect signal names
6 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX 416 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
7 module doesn't even have all POSIX signals :/. 417 module doesn't even have all POSIX signals :/.
1764.3 Fri Oct 3 09:18:43 CEST 2008 5864.3 Fri Oct 3 09:18:43 CEST 2008
