97.01
10 - fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but
11 not available, instead of throwing an exception.
12 - use File::Spec to get the tmpdir in t/*, to avoid needless
13 failures on (most, not mine :) windows boxes.
14
157.0 Fri Apr 13 06:33:30 CEST 2012
16 - child watchers are broken in POE 1.352 (also many earlier
17 versions) and there seems to be no way to work around it, as POE
18 itself is inherently racy. Document this regression and add a delay
19 in t/68_poe_03_child.t for the time being.
20 - new module AnyEvent::IO, that is a frontend to either a pure-perl
21 synchronous I/O implementation (AnyEvent::IO::Perl), or to the
22 asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO).
23 - load /etc/hosts only when DNS has no answer.
24 - stat /etc/hosts on every access and reload it if it changed.
25 - load /etc/hosts via AnyEvent::IO - potentially asynchronous.
26 - fix a buggy croak in the dh parameter reading in AnyEvent::TLS.
27 - AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As
28 a side effect, they now use true appending as opposed to libc
29 appending, and the file might not have been opened when the function
30 returns.
31 - the default logging level was not properly documented in a variety of
32 places, this has hopefully been rectified.
33 - updated uts46data.pl for unicode 6.1.0.
34 - made log messages generated by AnyEvent submodules not
35 include the package name anymore, as it will be logged
36 by default already.
37 - upgrade to the trick used by common-sense 3.5 to work
38 around extra warning torture/breakage under perl 5.15.x.
39 - log messages by anyevent are now ucfirst, are usually full
40 sentences and do no longer include the package name.
41 - the storable read type would sometimes throw an exception instead
42 of causing EBADMSG (analyzed by Maxime Soulé).
43 - work around a bug in openssl 1.0.1 which enforces a minimum rsa
44 keysize (reported by Paul Howarth).
45 - documented Rocco fabricating statements about AnyEvent and me.
46
476.14 Tue Jan 31 20:00:24 CET 2012
48 - AnyEvent::Impl::Tk was broken due to a mysterious "die" inside,
49 probably an editing mistake (reported by Darin McBride).
50
516.13 Thu Jan 12 07:27:01 CET 2012
52 - AnyEvent::Util::fork_call checked for POSIX availability in the wrong way,
53 causing it to fail if POSIX wasn't loaded already (analysed by Rock Power).
54 - AnyEvent::Handle::push_read (line => did pass $1 directly, so
55 regex-matching inside the callback would change the parameter, despite
56 $1 being dynamically scoped per-block. this perl bug is now being
57 worked around (testcase by Cindy Wang).
58
596.12 Mon Dec 12 13:21:10 CET 2011
60 - $! was clobbered by subsequent calls in tcp_connect, due to
61 the postpone not saving/restoring it (analyzed by Richard Garnish).
62
636.11 Tue Nov 22 10:36:05 CET 2011
64 - Tk cannot create windows when tainted unless you set a title, so
65 set a dummy title for AnyEvent's dummy mainwindow. How dummy.
66 - escape any nonprintable/nonascii characters when stringifying
67 backtraces.
68 - log the reason loading an interface module fails to load at level debug.
69
706.1 Tue Oct 4 19:44:30 CEST 2011
71 - INCOMPATIBLE CHANGE: the default log level is now "4" (error
72 and above), and some messages inside AnyEvent have been elevated
73 to higher log levels to print by default.
74 - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
75 - work around yet another signal race bug, newly introduced by POE. My
76 how that module sucks.
77 - add google public ipv6 dns as fallback servers, so AE::DNS can finally
78 support ipv6-only operation even with defaults (also use ::1 instead
79 of 127.0.0.1).
80 - give better guidelines on how to chose a logging level.
81 - AnyEvent::Log can now cap (limit) log message priority by context.
82 - AE::log will now save and restore $! and $@, so callers don't have to.
83 - AE::Strict now checks that registered fds are still valid at regular
84 intervals.
85 - skip frequently called 'require' calls if the module appears loaded.
86 - increase signal latency test timer considerably for poor little osx,
87 which can't be bothered with basic posix functionality such as signal
88 delivery.
89 - mention some debugging aids in the tutorial.
90 - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
91 - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
92 of the context as title.
93 - AnyEvent::Strict would not restore read-write access to $_ when a callback
94 died - this is a user bug, but since AE::Strict exists to help dbeugging...
95 - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
96 to work with it - the author is well aware of the issues but refuses
97 to fix them. This extreme step has been taken because the module actively
98 attacks the goals of AnyEvent and makes it harder for module authors to use
99 AnyEvent.
100
1016.02 Fri Aug 26 20:08:31 CEST 2011
102 - log_to_syslog now accepts facility strings.
103 - log_to_syslog would not allow facilities - "$facility|$level"
104 *literally* means that string. sheesh.
105 - the CPAN parser got confused and thought we provide Sys::Syslog, try
106 to work around.
107 - renamed AnyEvent::Impl::FLTK2 to FLTK.
108
1096.01 Fri Aug 26 07:04:11 CEST 2011
110 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include
111 the TTL as fourth element - this affects ->resolve, ->request
112 and ->dns_unpack indirectly. Convenience functions such as
113 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is
114 AnyEvent::Socket.
115 - INCOMPATIBLE CHANGE: backend authors now should not implement
116 one_event or loop, but instead the AnyEvent::CondVar::_wait and _poll
117 methods.
118 - INCOMPATIBLE CHANGE: verbosity levels have been redefined, see
119 AnyEvent (PERL_ANYEVENT_VERBOSE) and AnyEvent::Log for details.
120 - DEPRECIATION: please change
121 "use AnyEvent::Impl::Perl" to "use AnyEvent::Loop" and
122 "AnyEvent::Impl::Perl::loop" to "AnyEvent::Loop::run"
123 in your programs, for future compatibility.
124 - *blush* idle watcher emulation was borked.
125 - AnyEvent::Strict now checks the AE::xxx functions as well.
126 - querying too long domain names would barf deep inside AnyEvent::DNS - since
127 this is hard to avoid for applications, AnyEvent:.DNS::request now checks for
128 for too long domain names explicitly and passes an undef to the callback
129 instead (reported by James Bromberger).
130 - make AnyEvent::Util more robust against EINTR (analyzed by Andrew Suffield).
131 - new functions: AnyEvent::postpone, AnyEvent::log.
132 - new module: AnyEvent::Log, for simple logging needs.
133 - new env variable, PERL_ANYEVENT_LOG, for fine-grained logging config.
134 - new env variable, PERL_ANYEVENT_DEBUG_SHELL, to automatically start
135 a debug shell.
136 - new env variable, PERL_ANYEVENT_DEBUG_WRAP, to automatically enable
137 watcher instrumentation/wrapping (see AnyEvent::Debug::wrap).
138 - new env variable, PERL_ANYEVENT_HOSTS, to override the place where
139 /etc/hosts can be found.
140 - an empty PERL_ANYEVENT_RESOLV_CONF now selects the default
141 configuration.
142 - env variables can now be specified using AE_xyz instead of
143 PERL_ANYEVENT_xyz, subject to some rules.
144 - lots of new AnyEvent::Debug functionality.
145 - AnyEvent::Strict now checks for modifications of $_ by the callback
146 (by setting it to readonly while executing the callback, if possible).
147 - IO::Async sometimes cancels the wrong timer when you call cancel_timer.
148 Invest extra overhead to work around this peculiar behaviour.
149 - split the pure perl backend into a loop module and an impl
150 module (AnyEvent::Loop and AnyEvent::Impl::Perl).
151 - some read types (regex, netstring, json, storable) could
152 errornously keep an AE::Handle object alive on their own
153 (reported by Mohammad Toossi).
154 - AnyEvent::Socket::resolve_sockaddr and all functions using it now
155 supports /etc/hosts overrides.
156 - add more workarounds around child watcher bugs in IO::Async
157 and (newly introduced) in POE.
158 - use glib child watchers and try to work around its limitations,
159 if possible (based on a patch by Kevin Ryde).
160 - add support for FLTK (fltk2), via AnyEvent::Impl::FLTK2.
161 - many read types in AnyEvent::Handle would malfunction during
162 transitions to TLS because of a "delete $self->{rbuf}".
163 (reported by Gerald Galster).
164 - improve condvar blocking wait performance (probably only noticable
165 with faster backends), also make it easier for event loops that
166 do not support blocking waits.
167 - PERL_ANYEVENT_MODEL now also allows full module names, although
168 the usefulness of this feature is not yet clear.
169 - add tests for all supported event loops, conditional on PERL_ANYEVENT_LOOP_TESTS.
170 - add t/80_ssltext.t.
171 - no longer use AUTOLOAD for the initial loading (for no very good reason).
172 - tcp_server now tries to unlink unix domain sockets when it gets destroyed.
173 - do not run event loop detection multiple times when programs call their cached
174 copies of AnyEvent::detect.
175 - parse_hostport now accepts absolute paths als unix domain sockets.
176 - suppress the idiotic warning inside POE by patching the POE::Kernel
177 run flags instead of asking the user to jump through contortions.
178 - add Task::Weaken as dependency (as recommends only at this time).
179 - replace PF_UNSPEC by 0, for good old minix.
180
1816.0 (not officially released, but was on CPAN for about 15 minutes :/)
182
1835.34 Thu May 12 09:59:41 CEST 2011
184 - AE::TLS didn't support both cert_file and key at the same time,
185 due to some copy&paste bug (reported and analyzed by vti).
186 - improve AE::Handle timeout documentation slightly.
187
1885.33 Mon Feb 7 21:51:41 CET 2011
189 - never appeared on CPAN, for unknown reasons.
190 - AnyEvent::Handle on_connect_error - do not try to destroy a handle
191 object when it's already gone (analyzed by Ryan Bullock).
192 - update idna algorithm(s) to UTS#46 version 6.0.0.
193 - preserve trailing dot in idn_to_ascii - testsuite says to preserve,
194 uts46 says it's an error, and testsuite makes more sense.
195 - remove leading dots in idn_to_ascii - testsuite says to remove,
196 uts46 says it's an error, and testsuite makes more sense.
197 - fixed a bug in idn ignored character processing.
198 - passes the uts46 6.0.0 testsuite except for three cases which
199 apparently are bugs in the testsuite itself.
200 - passes the uts46 6.0.1 testsuite except for eleven cases which
201 apparently are bugs in the testsuite itself.
202
2035.31 Sun Jan 23 11:49:19 CET 2011
204 - work around a POE bug where POE would first poll for new events and
205 invoke handlers BEFORE handling the message queue.
206 - fix parsing of "domain" statement in resolv.conf (Johannes Plunien).
207 - stop_read now does just that in TLS mode. see its
208 documentation for caveats.
209 - update to common::sense 3.4 warning set (some warnings in perl impose
210 an arbitrary 32kb limit on regex matches, which affects
211 AnyEvent::Handle).
212 - AE::Handle had a broken rbuf_max method and missing wbuf_max method.
213 - new experimental AE::Handle::resettls method.
214
2155.3 Fri Dec 31 05:48:13 CET 2010
216 - major IOAsync patch by Paul Evans - 0.33 is required, as the major
217 issues with IO::Async have been solved in that version, including
218 the availabilty of a default loop!
219 - implement new wbuf_max parameter for AnyEvent::Handle.
220 - added Cocoa::EventLoop backend by Daisuke Murase.
221 - the default testsuite now honors PERL_ANYEVENT_MODEL (Paul Evans).
222 - clarify handle on_prepare documentation.
223 - set CLOEXEC flag on parent-side fd's in AnyEvent::Util::run_cmd,
224 to avoid leaking them to any child processes.
225 - try to force files into the arch-dependend lib directory, for the
226 half-"turly obsessive compulsive person"(s) that depend on it.
227
2285.29 Sun Dec 5 10:49:21 CET 2010
229 - convert EV backend to EV 4.00 API (so better upgrade EV too).
230 - AE::Handle: implement dynamic read_size adjustment, add
231 max_read_size parameter, reduce default read_size to 2048.
232 - add some FAQ entries for servers and/or on_eof vs. on_error.
233 - work around OS bugs (cygwin again) when lingering in AE::Handle.
234 - reduce memory usage slightly when connect was used in AE::Handle.
235 - wrok around more segfaults in Tk.
236 - document tls_ctx => undef as valid.
237 - detect WNOHANG value at compiletime.
238 - include some probably linux-only support for building AnyEvent
239 as part of the perl core.
240 - improve compatibility of t/08_idna.t to perl 5.8.
241 - make AnyEvent::Strict truly optional (in case somebody builds a
242 minimal perl...).
243
2445.28 Wed Oct 13 04:14:23 CEST 2010
245 - due to a glitch, AnyEvent's internal getprotobyname wasn't
246 actually used in tcp_server.
247 - implement AnyEvent::CondVar->new method, which was documented but
248 missing.
249 - support autoloading of read types in unshift_read.
250 - AnyEvent::Strict: do the test for invalid fh arguments differently,
251 resulting in more informative error messages.
252 - new AnyEvent::FAQ manpage.
253 - clarify that you can actually call push_read etc. in on_read.
254 - put keys and certs in /tmp, not into the current directory,
255 and document this in the SECURITY CONSIDERATIONS sections
256 of AnyEvent::TLS.
257 - support ";" as resolv.conf comment character in AnyEvent::DNS, as
258 requested by Ron Isaacson.
259 - document $AnyEvent::DNS::RESOLVER variable.
260 - incorporated major typo patches by Abhijit Menon-Sen.
261 - AnyEvent::Handle now croaks when negative timeouts are passed.
262 - add a shitload of TCP_xxx sockopt name constants to AnyEvent::Util,
263 undocumented, but who knows when they might come in handy.
264
2655.271 Tue Jun 8 12:05:46 CEST 2010
266 - backport to perl 5.8.x.
267
2685.27 Sun Jun 6 12:12:05 CEST 2010
269 - postpone differently in AnyEvent::Socket now, as
270 when not, canceling the connection attempt might fail
271 (found by Felix Antonius Wilhelm Ostmann).
272 - explicitly check for non-stream sockets in AE::Handle, too many
273 clueless people fell into the trap of this somehow working.
274 - simplified and reworked the "OTHER MODULES" section.
275 - better/more condvar examples.
276
2775.261 Wed Apr 28 16:13:36 CEST 2010
278 - AF_INET6 was not properly used from Socket6 during configuration
279 time (found by Andy Grundman).
280
2815.26 Mon Apr 12 04:49:35 CEST 2010
282 - don't generate spurious readyness notifications when select
283 returns EINTR in the pure perl backend (analysed and testcase
284 by Bas Denissen).
285 - give same examples in SYNOPSIS sections of AnyEvent and AE.
286 - provider faster implementations for AE::time/now/now_update for
287 EV and Perl backends.
288 - provide faster AE::cv and AE::time implementations for all
289 backends.
290 - no longer support lower/mixed-case signal names (this was
291 never documented nor universally supported).
292 - some more memory µ-optimisations, and somewhat less messy
293 code to cope with both AnyEvent and AE APIs.
294
2955.251 Sat Mar 13 00:58:21 CET 2010
296 - make test failed if it was run before make install on perl <=
297 5.8.8, and older versions of perl make our live very difficult,
298 so write constants.pl during Makefile.PL time.
299
3005.25 Sat Mar 13 00:23:14 CET 2010
301 - fix a race condition in AnyEvent::Handle that would cause
302 a "bio_read: unsupported method" error (in _another_
303 ssl connection) after user code threw an exception.
304 - added AnyEvent::Handle->destroyed method.
305 - speed up AnyEvent::Socket::format_address and ::format_ipv6.
306 - the AnyEvent::Util::fh_nonblocking function worked only
307 by lucky accident on win32.
308 - smaller and faster AnyEvent::Util::fh_nonblocking.
309 - when the (required!) Time::HiRes module is missing, AnyEvent
310 did not fall back to built-in time properly.
311 - do not load Fcntl at runtime, saving memory and loading time.
312 - precompile a number of constants and use them instead of runtime
313 detection and eval.
314 - free detection code after detection and similar memory optimisations.
315 - Perl backend timer interval best effort drift has been improved
316 (same algorithm as EV).
317 - update unicode idna mapping table.
318
3195.24 Tue Jan 5 11:39:43 CET 2010
320 - cygwin never reports errors from failed connects. 1.5 just gives
321 you continous readyness and EAGAIN, 1.7 is even more broken and
322 just hangs. work around both issues in a cygwin-specific hack.
323 - improve idle watcher documentation slightly.
324
3255.23 Sun Dec 20 23:48:00 CET 2009
326 - support IDNs in resolve_sockaddr, and therefore in tcp_connect.
327 - implement punycode_encode/decode, idn_nameprep,
328 idn_to_ascii and idn_to_unicode operations in AnyEvent::Util.
329 - provide $AE::VERSION.
330 - removed traces of "no strict 'refs'".
331
3325.22 Sat Dec 5 03:51:13 CET 2009
333 - downgrade-or-fail in AnyEvent::Handle::push_write, to
334 diagnose encoding failures earlier and more succinctly.
335 (this works around bugs in perl, throwing away encoding info
336 when passing scalar data to extensions).
337 - add more examples to AnyEvent::Socket manpage.
338 - upgrade internal warning set to the same as common::sense 2.03.
339 - use pack "n/a*" for pre-5.8.9 perl compatibility in AnyEvent::DNS
340 (John Beppu).
341 - AnyEvent::Socket::inet_aton now properly supports ipv6, as documented.
342 - add google public dns servers to fallback server set and make sure
343 we load-balance properly between the three sets. also add all
344 fallback dns servers, not just a random one, to each dns config.
345
3465.21 Thu Nov 19 02:48:47 CET 2009
347 - fix a problem where socket constants were called with parameters
348 (spotted by David Friedland).
349 - fork_call never use'd POSIX (reported by Daisuke Maki).
350 - improve perl 5.6 compatibility further (but it still won't work
351 unless you rip out everything but the core).
352 - prefer Net::DNS::Resolver over ipconfig, if installed, on win32.
353 uses 10MB of RAM, but doesn't open a console window. *sigh*.
354
3555.202 Wed Oct 14 22:35:44 CEST 2009
356 - AnyEvent::DNS would unexpectedly clobber $_ under windows
357 (analysed by Matthias Waldorf).
358 - AnyEvent::Handle::run_cmd can now pass the PID of the
359 newly-created process, which is much less useful than it might
360 sound (based on patch by Yann Kerherve).
361
3625.201 Tue Sep 29 12:09:25 CEST 2009
363 - AnyEvent:Handle::on_starttls/on_stoptls methods were broken
364 (reported by Torsten Foertsch).
365 - common::sense 2.0 could cause tcp_server to throw an exception
366 (analysed by elmex).
367
3685.2 Mon Sep 14 07:04:49 CEST 2009
369 - INCOMPATIBLE CHANGE: do no longer support register_read_type
370 and register_write_type in AnyEvent::Handle, instead support
371 package names (the facility was mostly abused).
372 - implement "packagename-as-read/write type" support in
373 AnyEvent::Handle.
374 - AnyEvent::Handle: new options "keepalive" and "oobinline".
375 - oobinline set by default to avoid security issues.
376 - the pure-perl event loop backend wrongly detected times() fallback
377 support (spotted by Pavel Boldin).
378
3795.12 Tue Sep 1 20:26:50 CEST 2009
380 - be more lenient when parsing resolv.conf files, as some people
381 use hashmarks as comment indicator inside directives (reported
382 by Michael S. Fischer).
383 - use same set of warnings as common::sense 2.0.
384 - fix a potential 32 bit overflow issue due to perl having problems
385 with large hex constants in the Perl backend.
386 - do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS
387 by default.
388 - fix some prototypes.
389 - (optionally) require Async::Interrupt 1.02.
390 - replace opendns fallbacks by verizon/level3 public dns servers.
391
3925.112 Fri Aug 21 13:59:04 CEST 2009
393 - AnyEvent::Handle could cause hard crashes in Net::SSLeay when
394 using starttls with an illegal/uncreatable tls context.
395 - port to broken win32 perls.

305 - AnyEvent will now install a no-op signal handler for SIGPIPE, 699 - AnyEvent will now install a no-op signal handler for SIGPIPE,
306 unless one has been installed already. 700 unless one has been installed already.
