147.14
15 - fix a crash bug in AnyEvent::Handle with openssl 1.1.0 (patched
16 by Paul Howarth and apparently tracked down by Mike McCauley).
17 - AnyEvent::Handle->keepalive was documented (and defined) twice
18 (found by Matt Merhar).
19 - AnyEvent::Socket::tcp_bind/tcp_server would immediately unlink a unix
20 listening socket unless a guard is used. Change this so that no
21 cleanup will be performed unless a guard is used and document this more
22 clearly.
23 - make tcp_bind/tcp_server error messages more regular.
24 - work around latest perl upstream breakage - this time, perl5porters were
25 apparently bullied by a bogus CVE (CVE-2016-1238), and since distros
26 stupidly apply anything that has "security fix" stamped on it, it's likely
27 going to be a problem in practise (and working around it is trivial on
28 windows and unix).
29
307.13 Sat Sep 17 04:31:49 CEST 2016
31 - Only call tlsext_host_name for non-empty common names (reported
32 by Maxime Soulé).
33 - log a (single) notice message if SNI is not supported.
34 - upgrade to UTS-46:9.0.0 draft and switch to non-transitional
35 behaviour, beating thunderbird, ie, edge, chrome and safari to it :)
36 (see also https://bugzilla.mozilla.org/show_bug.cgi?id=1218179)
37 - turns out the UTS-46 IDNA testcase failures were indeed bugs in the
38 testcases and the specification and not in the code - the post-9.0.0
39 unicode files have all known problems fixed, so finally the AnyEvent
40 IDNA implementation can pass the full IDNA testsuite - without needing
41 a single fix :)
42 - guarantee (and document) that condvar callbacks will be removed
43 on invocation - important to avoid circular references.
44
457.12 Wed Jan 27 19:12:26 CET 2016
46 - use common name as hostname for tls connects, if Net::SSLeay
47 supports SNI.
48 - fix documentation of tls_autostart read type in AnyEvent::Handle,
49 analyzed by Felix Ostmann.
50
517.11 Thu Jul 16 14:36:00 CEST 2015
52 - AnyEvent::Socket::parse_ipv6 could accept malformed ipv6
53 addresses (extra "::" at end and similar cases).
54 - add a more explicit warning to AnyEvent::Handle that it doesn't
55 work on files, people keep getting confused.
56 - new function AnyEvent::Socket::tcp_bind.
57 - new functions AnyEvent::fh_block and AnyEvent::fh_unblock.
58 - aligned ipv6 address formatting with RFC 5952 (by not shortening
59 a single :0: to ::).
60 - added stability canary support.
61
627.09 Sat May 2 16:38:53 CEST 2015
63 - AnyEvent::Debug called an internal function (AnyEvent::Log::ft)
64 that was renamed to AnyEvent::Log:format_time. uinder its old name
65 (analyzed by Michael Stovenour).
66 - update AnyEvent::DNS fallback resolver addresses:
67 seems google effectively killed most other free dns resolvers,
68 so remove them, but add cable and wireless (ecrc) since it was
69 stable for 20 years or so, official or not, and there should be
70 an alternative to google.
71 - perl5porters broke windows error codes in 5.20, and mapped
72 WSAEWOULDBLOCK on the (different) EWOULDBLOCK error code, and
73 WSAEINPROGRESS into the incompatible ERINPROGRESS code, probably
74 because they were so cool. They probably broke other error codes
75 for no reason, too, but I didn't care for checking, it's too
76 depressing. This version only works around the WSAEWOULDBLOCK
77 issue, because I don't have a nice way to work around the
78 WSAEINPROGRESS bug.
79
807.08 Wed Dec 10 05:27:17 CET 2014
81 - work around a newly introduced bug in Socket 2.011 (an
82 errornous sun_length check) (analyzed by Maxime Soulé).
83 - AnyEvent::TLS didn't load (but refer to) AnyEvent::Socket
84 (analyzed by Ben Magistro).
85 - AnyEvent::Strict will now confess, not croak. This is in line with
86 it being a development/debugging tool.
87 - work around a number of libglib bugs (debug builds of libglib enforce
88 certain undocumented behaviour patterns such as not being able to
89 remove a child watch source after it has fired, which we will try
90 to emulate to avoid "criticals". what where they thinking...).
91 - mention json security issues in AnyEvent::Handle, now that Douglas
92 Crockford has foolishly and incompatibly changed JSON.
93 - changed default dns resolver "max_outstanding" value from 1 to 10,
94 the latter beinfg the intended value all along
95 (reported by Ilya Chesnokov).
96 - added new "AnyEvent::Impl::UV" interface module to the UV event lib
97 (written by Mike Lowell).
98
997.07 Tue Dec 17 17:45:02 CET 2013
100 - the documentation for custom tls verify schemes was wrong. make it agree
101 with the code (reported by Maxime Soulé).
102 - added cbor read and write types to AnyEvent::Handle (using CBOR::XS).
103 - work around an API change in openssl that could cause wrong tls connection
104 aborts, likely on windows only (analyzed by sten).
105 - calling AnyEvent->now_update with AnyEvent::Impl::Perl caused an
106 endless loop (reported by Dietrich Rebmann).
107 - add tlsv1_1 and tlsv1_2 protocols to AnyEvent::TLS
108 (patch by Maxime Soulé).
109 - document AnyEvent::Impl::IOAsync::set_loop and
110 $AnyEvent::Impl::IOAsync::LOOP. Though only documented now, this
111 functionality has _always_ been available.
112 - force a toplevel domain name in t/81_hosts.t (analyzed by
113 David Jack Wange Olrik).
114 - document that AnyEvent::Log uses AnyEvent::IO.
115 - warn about AnyEvent::Filesys::Notify performance.
116 - praise the joys of AnyEvent::Fork::*.
117 - time for an =encoding directive.
118 - do no longer use JSON to create a default json coder, use
119 JSON::XS or JSON::PP directly.
120
1217.05 Wed Aug 21 10:38:08 CEST 2013
122 - uts46data.pl couldn't be found due to wrong naming of the file
123 (reported by Fulko Hew).
124 - handle lone \015's properly in AE::Handle's default line read
125 (reported by various people).
126 - untaint ip addresses found in /etc/hosts (patch by José Micó).
127 - the memleak fix in 7.03 caused resolving via /etc/hosts to always
128 fail on first use (reported and testcase by Andrew Whatson).
129 - expose AnyEvent::Log::format_time, and allow users to redefine it.
130 - expose AnyEvent::Log::default_format, and allow redefinition.
131 - expose AnyEvent::Log::fatal_exit, to allow redefinition.
132 - AnyEvent::Debug shell can now run coro shell commands, if available.
133 - t/63* tests were wrongly in MANIFEST.
134 - kernel.org's finger server went MIA, switch to freebsd.org and
135 icculus.org.
136 - clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO
137 to function asynchronously (reported by Daniel Carosone).
138 - hard-disable $^W in most tests, it generates too much garbage output.
139 - use a (hopefully) more future-proof method to emulate common::sense.
140 - upgrade to UTS-46:6.2.0.
141 - switch to INSTLIB from INSTLIBDIR, as INSTLIBDIR was wrongly
142 documented. should not affect anything.
143
1447.04 Thu Nov 15 02:23:58 CET 2012
145 - debugging code left in.
146
1477.03 Thu Nov 15 02:16:11 CET 2012
148 - AnyEvent::Socket::inet_aton did not work when dns resolution was
149 used to find the addresses (analyzed and patch by Maxime Soulé).
150 - fix a memory leak in the /etc/hosts lookup code when hosts don't
151 resolve and are not in hosts (analyzed by sten).
152
1537.02 Tue Aug 14 04:27:58 CEST 2012
154 - AnyEvent::Util::run_cmd could block indefinitely (analyzed and test
155 program by Yorhel).
156 - verified that AnyEvent::Socket follows RFC5952.
157 - try to parse "ADDR#PORT" in addition to "ADDR PORT".
158
1597.01 Sun May 13 01:03:17 CEST 2012
160 - fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but
161 not available, instead of throwing an exception.
162 - use File::Spec to get the tmpdir in t/*, to avoid needless
163 failures on (most, not mine :) windows boxes.
164 - new handle read types: tls_detect and tls_autostart.
165
1667.0 Fri Apr 13 06:33:30 CEST 2012
167 - child watchers are broken in POE 1.352 (also many earlier
168 versions) and there seems to be no way to work around it, as POE
169 itself is inherently racy. Document this regression and add a delay
170 in t/68_poe_03_child.t for the time being.
171 - new module AnyEvent::IO, that is a frontend to either a pure-perl
172 synchronous I/O implementation (AnyEvent::IO::Perl), or to the
173 asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO).
174 - load /etc/hosts only when DNS has no answer.
175 - stat /etc/hosts on every access and reload it if it changed.
176 - load /etc/hosts via AnyEvent::IO - potentially asynchronous.
177 - fix a buggy croak in the dh parameter reading in AnyEvent::TLS.
178 - AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As
179 a side effect, they now use true appending as opposed to libc
180 appending, and the file might not have been opened when the function
181 returns.
182 - the default logging level was not properly documented in a variety of
183 places, this has hopefully been rectified.
184 - updated uts46data.pl for unicode 6.1.0.
185 - made log messages generated by AnyEvent submodules not
186 include the package name anymore, as it will be logged
187 by default already.
188 - upgrade to the trick used by common-sense 3.5 to work
189 around extra warning torture/breakage under perl 5.15.x.
190 - log messages by anyevent are now ucfirst, are usually full
191 sentences and do no longer include the package name.
192 - the storable read type would sometimes throw an exception instead
193 of causing EBADMSG (analyzed by Maxime Soulé).
194 - work around a bug in openssl 1.0.1 which enforces a minimum rsa
195 keysize (reported by Paul Howarth).
196 - documented Rocco fabricating statements about AnyEvent and me.
197
1986.14 Tue Jan 31 20:00:24 CET 2012
199 - AnyEvent::Impl::Tk was broken due to a mysterious "die" inside,
200 probably an editing mistake (reported by Darin McBride).
201
2026.13 Thu Jan 12 07:27:01 CET 2012
203 - AnyEvent::Util::fork_call checked for POSIX availability in the wrong way,
204 causing it to fail if POSIX wasn't loaded already (analysed by Rock Power).
205 - AnyEvent::Handle::push_read (line => did pass $1 directly, so
206 regex-matching inside the callback would change the parameter, despite
207 $1 being dynamically scoped per-block. this perl bug is now being
208 worked around (testcase by Cindy Wang).
209
2106.12 Mon Dec 12 13:21:10 CET 2011
211 - $! was clobbered by subsequent calls in tcp_connect, due to
212 the postpone not saving/restoring it (analyzed by Richard Garnish).
213
2146.11 Tue Nov 22 10:36:05 CET 2011
215 - Tk cannot create windows when tainted unless you set a title, so
216 set a dummy title for AnyEvent's dummy mainwindow. How dummy.
217 - escape any nonprintable/nonascii characters when stringifying
218 backtraces.
219 - log the reason loading an interface module fails to load at level debug.
220
2216.1 Tue Oct 4 19:44:30 CEST 2011
222 - INCOMPATIBLE CHANGE: the default log level is now "4" (error
223 and above), and some messages inside AnyEvent have been elevated
224 to higher log levels to print by default.
225 - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
226 - work around yet another signal race bug, newly introduced by POE. My
227 how that module sucks.
228 - add google public ipv6 dns as fallback servers, so AE::DNS can finally
229 support ipv6-only operation even with defaults (also use ::1 instead
230 of 127.0.0.1).
231 - give better guidelines on how to chose a logging level.
232 - AnyEvent::Log can now cap (limit) log message priority by context.
233 - AE::log will now save and restore $! and $@, so callers don't have to.
234 - AE::Strict now checks that registered fds are still valid at regular
235 intervals.
236 - skip frequently called 'require' calls if the module appears loaded.
237 - increase signal latency test timer considerably for poor little osx,
238 which can't be bothered with basic posix functionality such as signal
239 delivery.
240 - mention some debugging aids in the tutorial.
241 - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
242 - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
243 of the context as title.
244 - AnyEvent::Strict would not restore read-write access to $_ when a callback
245 died - this is a user bug, but since AE::Strict exists to help dbeugging...
246 - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
247 to work with it - the author is well aware of the issues but refuses
248 to fix them. This extreme step has been taken because the module actively
249 attacks the goals of AnyEvent and makes it harder for module authors to use
250 AnyEvent.
251
2526.02 Fri Aug 26 20:08:31 CEST 2011
253 - log_to_syslog now accepts facility strings.
254 - log_to_syslog would not allow facilities - "$facility|$level"
255 *literally* means that string. sheesh.
256 - the CPAN parser got confused and thought we provide Sys::Syslog, try
257 to work around.
258 - renamed AnyEvent::Impl::FLTK2 to FLTK.
259
2606.01 Fri Aug 26 07:04:11 CEST 2011
261 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include
262 the TTL as fourth element - this affects ->resolve, ->request
263 and ->dns_unpack indirectly. Convenience functions such as
264 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is
265 AnyEvent::Socket.
266 - INCOMPATIBLE CHANGE: backend authors now should not implement
267 one_event or loop, but instead the AnyEvent::CondVar::_wait and _poll
268 methods.
269 - INCOMPATIBLE CHANGE: verbosity levels have been redefined, see
270 AnyEvent (PERL_ANYEVENT_VERBOSE) and AnyEvent::Log for details.
271 - DEPRECIATION: please change
272 "use AnyEvent::Impl::Perl" to "use AnyEvent::Loop" and
273 "AnyEvent::Impl::Perl::loop" to "AnyEvent::Loop::run"
274 in your programs, for future compatibility.
275 - *blush* idle watcher emulation was borked.
276 - AnyEvent::Strict now checks the AE::xxx functions as well.
277 - querying too long domain names would barf deep inside AnyEvent::DNS - since
278 this is hard to avoid for applications, AnyEvent:.DNS::request now checks for
279 for too long domain names explicitly and passes an undef to the callback
280 instead (reported by James Bromberger).
281 - make AnyEvent::Util more robust against EINTR (analyzed by Andrew Suffield).
282 - new functions: AnyEvent::postpone, AnyEvent::log.
283 - new module: AnyEvent::Log, for simple logging needs.
284 - new env variable, PERL_ANYEVENT_LOG, for fine-grained logging config.
285 - new env variable, PERL_ANYEVENT_DEBUG_SHELL, to automatically start
286 a debug shell.
287 - new env variable, PERL_ANYEVENT_DEBUG_WRAP, to automatically enable
288 watcher instrumentation/wrapping (see AnyEvent::Debug::wrap).
289 - new env variable, PERL_ANYEVENT_HOSTS, to override the place where
290 /etc/hosts can be found.
291 - an empty PERL_ANYEVENT_RESOLV_CONF now selects the default
292 configuration.
293 - env variables can now be specified using AE_xyz instead of
294 PERL_ANYEVENT_xyz, subject to some rules.
295 - lots of new AnyEvent::Debug functionality.
296 - AnyEvent::Strict now checks for modifications of $_ by the callback
297 (by setting it to readonly while executing the callback, if possible).
298 - IO::Async sometimes cancels the wrong timer when you call cancel_timer.
299 Invest extra overhead to work around this peculiar behaviour.
300 - split the pure perl backend into a loop module and an impl
301 module (AnyEvent::Loop and AnyEvent::Impl::Perl).
302 - some read types (regex, netstring, json, storable) could
303 errornously keep an AE::Handle object alive on their own
304 (reported by Mohammad Toossi).
305 - AnyEvent::Socket::resolve_sockaddr and all functions using it now
306 supports /etc/hosts overrides.
307 - add more workarounds around child watcher bugs in IO::Async
308 and (newly introduced) in POE.
309 - use glib child watchers and try to work around its limitations,
310 if possible (based on a patch by Kevin Ryde).
311 - add support for FLTK (fltk2), via AnyEvent::Impl::FLTK2.
312 - many read types in AnyEvent::Handle would malfunction during
313 transitions to TLS because of a "delete $self->{rbuf}".
314 (reported by Gerald Galster).
315 - improve condvar blocking wait performance (probably only noticable
316 with faster backends), also make it easier for event loops that
317 do not support blocking waits.
318 - PERL_ANYEVENT_MODEL now also allows full module names, although
319 the usefulness of this feature is not yet clear.
320 - add tests for all supported event loops, conditional on PERL_ANYEVENT_LOOP_TESTS.
321 - add t/80_ssltext.t.
322 - no longer use AUTOLOAD for the initial loading (for no very good reason).
323 - tcp_server now tries to unlink unix domain sockets when it gets destroyed.
324 - do not run event loop detection multiple times when programs call their cached
325 copies of AnyEvent::detect.
326 - parse_hostport now accepts absolute paths als unix domain sockets.
327 - suppress the idiotic warning inside POE by patching the POE::Kernel
328 run flags instead of asking the user to jump through contortions.
329 - add Task::Weaken as dependency (as recommends only at this time).
330 - replace PF_UNSPEC by 0, for good old minix.
331
3326.0 (not officially released, but was on CPAN for about 15 minutes :/)
333
3345.34 Thu May 12 09:59:41 CEST 2011
335 - AE::TLS didn't support both cert_file and key at the same time,
336 due to some copy&paste bug (reported and analyzed by vti).
337 - improve AE::Handle timeout documentation slightly.
338
3395.33 Mon Feb 7 21:51:41 CET 2011
340 - never appeared on CPAN, for unknown reasons.
341 - AnyEvent::Handle on_connect_error - do not try to destroy a handle
342 object when it's already gone (analyzed by Ryan Bullock).
343 - update idna algorithm(s) to UTS#46 version 6.0.0.
344 - preserve trailing dot in idn_to_ascii - testsuite says to preserve,
345 uts46 says it's an error, and testsuite makes more sense.
346 - remove leading dots in idn_to_ascii - testsuite says to remove,
347 uts46 says it's an error, and testsuite makes more sense.
348 - fixed a bug in idn ignored character processing.
349 - passes the uts46 6.0.0 testsuite except for three cases which
350 apparently are bugs in the testsuite itself.
351 - passes the uts46 6.0.1 testsuite except for eleven cases which
352 apparently are bugs in the testsuite itself.

85.31 Sun Jan 23 11:49:19 CET 2011 3545.31 Sun Jan 23 11:49:19 CET 2011
9 - work around a POE bug where POE would first poll for new events and 355 - work around a POE bug where POE would first poll for new events and
10 invoke handlers BEFORE handling the message queue. 356 invoke handlers BEFORE handling the message queue.
11 - fix parsing of "domain" statement in resolv.conf (Johannes Plunien). 357 - fix parsing of "domain" statement in resolv.conf (Johannes Plunien).
12 - stop_read now does just that in TLS mode. see its 358 - stop_read now does just that in TLS mode. see its
13 documentation for caveats. 359 documentation for caveats.
14 - update to common::sense 3.4 warning set. 360 - update to common::sense 3.4 warning set (some warnings in perl impose
361 an arbitrary 32kb limit on regex matches, which affects
362 AnyEvent::Handle).
15 - AE::Handle had a broken rbuf_max method and missing wbuf_max method. 363 - AE::Handle had a broken rbuf_max method and missing wbuf_max method.
16 - new experimental AE::Handle::resettls method. 364 - new experimental AE::Handle::resettls method.
