197.15 Tue Feb 26 03:07:42 CET 2019
20 - INCOMPATIBLE CHANGE: AnyEvent::Handle's tls_detect documentation gave
21 separate major and minor versions, while code passed only a single
22 value. This version follows the documentation and now passes separate
23 major and minor values.
24 - work around Net::SSLeay not having been ported to openssl 1.1, but many
25 distributions compiling it against openssl 1.1, which unfortunately
26 succeeds and results in a very broken module.
27 - AnyEvent::DNS::dns_unpack now stores the original DNS packet
28 in the __ member, to allow decoding of undecodable resouce records
29 containing compressed domian names.
30 - AnyEvent::Socket::parse_ipv6 would NOT, as advertised, accept ipv4
31 addresses. It now does and converts them to ipv4 mapped addresses.
32 - support CAA records, based on patch by Steve Atkins.
33 - add freenom and cloudflare nameservers as dns fallback.
34 - AnyEvent::Strict would not properly ward against io watchers
35 on files when the handle passed was a file descriptor.
36 - document "internal" variables used by the dns en-/decoder to allow
37 enterprising users to extend them in a semi-official way.
38
397.14 Sat Jun 24 01:44:19 CEST 2017
40 - fix a crash bug in AnyEvent::Handle with openssl 1.1.0 (patched
41 by Paul Howarth and apparently tracked down by Mike McCauley).
42 - AnyEvent::Handle->keepalive was documented (and defined) twice
43 (found by Matt Merhar).
44 - AnyEvent::Socket::tcp_bind/tcp_server would immediately unlink a unix
45 listening socket unless a guard is used. Change this so that no
46 cleanup will be performed unless a guard is used and document this more
47 clearly.
48 - make tcp_bind/tcp_server error messages more regular.
49 - work around latest perl upstream breakage - this time, perl5porters were
50 apparently bullied by a bogus CVE (CVE-2016-1238), and since distros
51 stupidly apply anything that has "security fix" stamped on it, it's likely
52 going to be a problem in practise (and working around it is trivial on
53 windows and unix).
54 - add TCP_FASTOPEN/MSG_FASTOPEN and MSG_NOSIGNAL/MSG_MORE/MSG_DONTWAIT
55 to constants.
56 - update warnings to common::sense 3.74 standards.
57
587.13 Sat Sep 17 04:31:49 CEST 2016
59 - Only call tlsext_host_name for non-empty common names (reported
60 by Maxime Soulé).
61 - log a (single) notice message if SNI is not supported.
62 - upgrade to UTS-46:9.0.0 draft and switch to non-transitional
63 behaviour, beating thunderbird, ie, edge, chrome and safari to it :)
64 (see also https://bugzilla.mozilla.org/show_bug.cgi?id=1218179)
65 - turns out the UTS-46 IDNA testcase failures were indeed bugs in the
66 testcases and the specification and not in the code - the post-9.0.0
67 unicode files have all known problems fixed, so finally the AnyEvent
68 IDNA implementation can pass the full IDNA testsuite - without needing
69 a single fix :)
70 - guarantee (and document) that condvar callbacks will be removed
71 on invocation - important to avoid circular references.
72
737.12 Wed Jan 27 19:12:26 CET 2016
74 - use common name as hostname for tls connects, if Net::SSLeay
75 supports SNI.
76 - fix documentation of tls_autostart read type in AnyEvent::Handle,
77 analyzed by Felix Ostmann.
78
797.11 Thu Jul 16 14:36:00 CEST 2015
80 - AnyEvent::Socket::parse_ipv6 could accept malformed ipv6
81 addresses (extra "::" at end and similar cases).
82 - add a more explicit warning to AnyEvent::Handle that it doesn't
83 work on files, people keep getting confused.
84 - new function AnyEvent::Socket::tcp_bind.
85 - new functions AnyEvent::fh_block and AnyEvent::fh_unblock.
86 - aligned ipv6 address formatting with RFC 5952 (by not shortening
87 a single :0: to ::).
88 - added stability canary support.
89
907.09 Sat May 2 16:38:53 CEST 2015
91 - AnyEvent::Debug called an internal function (AnyEvent::Log::ft)
92 that was renamed to AnyEvent::Log:format_time. uinder its old name
93 (analyzed by Michael Stovenour).
94 - update AnyEvent::DNS fallback resolver addresses:
95 seems google effectively killed most other free dns resolvers,
96 so remove them, but add cable and wireless (ecrc) since it was
97 stable for 20 years or so, official or not, and there should be
98 an alternative to google.
99 - perl5porters broke windows error codes in 5.20, and mapped
100 WSAEWOULDBLOCK on the (different) EWOULDBLOCK error code, and
101 WSAEINPROGRESS into the incompatible ERINPROGRESS code, probably
102 because they were so cool. They probably broke other error codes
103 for no reason, too, but I didn't care for checking, it's too
104 depressing. This version only works around the WSAEWOULDBLOCK
105 issue, because I don't have a nice way to work around the
106 WSAEINPROGRESS bug.
107
1087.08 Wed Dec 10 05:27:17 CET 2014
109 - work around a newly introduced bug in Socket 2.011 (an
110 errornous sun_length check) (analyzed by Maxime Soulé).
111 - AnyEvent::TLS didn't load (but refer to) AnyEvent::Socket
112 (analyzed by Ben Magistro).
113 - AnyEvent::Strict will now confess, not croak. This is in line with
114 it being a development/debugging tool.
115 - work around a number of libglib bugs (debug builds of libglib enforce
116 certain undocumented behaviour patterns such as not being able to
117 remove a child watch source after it has fired, which we will try
118 to emulate to avoid "criticals". what where they thinking...).
119 - mention json security issues in AnyEvent::Handle, now that Douglas
120 Crockford has foolishly and incompatibly changed JSON.
121 - changed default dns resolver "max_outstanding" value from 1 to 10,
122 the latter beinfg the intended value all along
123 (reported by Ilya Chesnokov).
124 - added new "AnyEvent::Impl::UV" interface module to the UV event lib
125 (written by Mike Lowell).
126
1277.07 Tue Dec 17 17:45:02 CET 2013
128 - the documentation for custom tls verify schemes was wrong. make it agree
129 with the code (reported by Maxime Soulé).
130 - added cbor read and write types to AnyEvent::Handle (using CBOR::XS).
131 - work around an API change in openssl that could cause wrong tls connection
132 aborts, likely on windows only (analyzed by sten).
133 - calling AnyEvent->now_update with AnyEvent::Impl::Perl caused an
134 endless loop (reported by Dietrich Rebmann).
135 - add tlsv1_1 and tlsv1_2 protocols to AnyEvent::TLS
136 (patch by Maxime Soulé).
137 - document AnyEvent::Impl::IOAsync::set_loop and
138 $AnyEvent::Impl::IOAsync::LOOP. Though only documented now, this
139 functionality has _always_ been available.
140 - force a toplevel domain name in t/81_hosts.t (analyzed by
141 David Jack Wange Olrik).
142 - document that AnyEvent::Log uses AnyEvent::IO.
143 - warn about AnyEvent::Filesys::Notify performance.
144 - praise the joys of AnyEvent::Fork::*.
145 - time for an =encoding directive.
146 - do no longer use JSON to create a default json coder, use
147 JSON::XS or JSON::PP directly.
148
1497.05 Wed Aug 21 10:38:08 CEST 2013
150 - uts46data.pl couldn't be found due to wrong naming of the file
151 (reported by Fulko Hew).
152 - handle lone \015's properly in AE::Handle's default line read
153 (reported by various people).
154 - untaint ip addresses found in /etc/hosts (patch by José Micó).
155 - the memleak fix in 7.03 caused resolving via /etc/hosts to always
156 fail on first use (reported and testcase by Andrew Whatson).
157 - expose AnyEvent::Log::format_time, and allow users to redefine it.
158 - expose AnyEvent::Log::default_format, and allow redefinition.
159 - expose AnyEvent::Log::fatal_exit, to allow redefinition.
160 - AnyEvent::Debug shell can now run coro shell commands, if available.
161 - t/63* tests were wrongly in MANIFEST.
162 - kernel.org's finger server went MIA, switch to freebsd.org and
163 icculus.org.
164 - clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO
165 to function asynchronously (reported by Daniel Carosone).
166 - hard-disable $^W in most tests, it generates too much garbage output.
167 - use a (hopefully) more future-proof method to emulate common::sense.
168 - upgrade to UTS-46:6.2.0.
169 - switch to INSTLIB from INSTLIBDIR, as INSTLIBDIR was wrongly
170 documented. should not affect anything.
171
1727.04 Thu Nov 15 02:23:58 CET 2012
173 - debugging code left in.
174
1757.03 Thu Nov 15 02:16:11 CET 2012
176 - AnyEvent::Socket::inet_aton did not work when dns resolution was
177 used to find the addresses (analyzed and patch by Maxime Soulé).
178 - fix a memory leak in the /etc/hosts lookup code when hosts don't
179 resolve and are not in hosts (analyzed by sten).
180
1817.02 Tue Aug 14 04:27:58 CEST 2012
182 - AnyEvent::Util::run_cmd could block indefinitely (analyzed and test
183 program by Yorhel).
184 - verified that AnyEvent::Socket follows RFC5952.
185 - try to parse "ADDR#PORT" in addition to "ADDR PORT".
186
1877.01 Sun May 13 01:03:17 CEST 2012
188 - fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but
189 not available, instead of throwing an exception.
190 - use File::Spec to get the tmpdir in t/*, to avoid needless
191 failures on (most, not mine :) windows boxes.
192 - new handle read types: tls_detect and tls_autostart.
193
1947.0 Fri Apr 13 06:33:30 CEST 2012
195 - child watchers are broken in POE 1.352 (also many earlier
196 versions) and there seems to be no way to work around it, as POE
197 itself is inherently racy. Document this regression and add a delay
198 in t/68_poe_03_child.t for the time being.
199 - new module AnyEvent::IO, that is a frontend to either a pure-perl
200 synchronous I/O implementation (AnyEvent::IO::Perl), or to the
201 asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO).
202 - load /etc/hosts only when DNS has no answer.
203 - stat /etc/hosts on every access and reload it if it changed.
204 - load /etc/hosts via AnyEvent::IO - potentially asynchronous.
205 - fix a buggy croak in the dh parameter reading in AnyEvent::TLS.
206 - AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As
207 a side effect, they now use true appending as opposed to libc
208 appending, and the file might not have been opened when the function
209 returns.
210 - the default logging level was not properly documented in a variety of
211 places, this has hopefully been rectified.
212 - updated uts46data.pl for unicode 6.1.0.
213 - made log messages generated by AnyEvent submodules not
214 include the package name anymore, as it will be logged
215 by default already.
216 - upgrade to the trick used by common-sense 3.5 to work
217 around extra warning torture/breakage under perl 5.15.x.
218 - log messages by anyevent are now ucfirst, are usually full
219 sentences and do no longer include the package name.
220 - the storable read type would sometimes throw an exception instead
221 of causing EBADMSG (analyzed by Maxime Soulé).
222 - work around a bug in openssl 1.0.1 which enforces a minimum rsa
223 keysize (reported by Paul Howarth).
224 - documented Rocco fabricating statements about AnyEvent and me.
225
2266.14 Tue Jan 31 20:00:24 CET 2012
227 - AnyEvent::Impl::Tk was broken due to a mysterious "die" inside,
228 probably an editing mistake (reported by Darin McBride).
229
2306.13 Thu Jan 12 07:27:01 CET 2012
231 - AnyEvent::Util::fork_call checked for POSIX availability in the wrong way,
232 causing it to fail if POSIX wasn't loaded already (analysed by Rock Power).
233 - AnyEvent::Handle::push_read (line => did pass $1 directly, so
234 regex-matching inside the callback would change the parameter, despite
235 $1 being dynamically scoped per-block. this perl bug is now being
236 worked around (testcase by Cindy Wang).
237
2386.12 Mon Dec 12 13:21:10 CET 2011
239 - $! was clobbered by subsequent calls in tcp_connect, due to
240 the postpone not saving/restoring it (analyzed by Richard Garnish).
241
2426.11 Tue Nov 22 10:36:05 CET 2011
243 - Tk cannot create windows when tainted unless you set a title, so
244 set a dummy title for AnyEvent's dummy mainwindow. How dummy.
245 - escape any nonprintable/nonascii characters when stringifying
246 backtraces.
247 - log the reason loading an interface module fails to load at level debug.
248
2496.1 Tue Oct 4 19:44:30 CEST 2011
250 - INCOMPATIBLE CHANGE: the default log level is now "4" (error
251 and above), and some messages inside AnyEvent have been elevated
252 to higher log levels to print by default.
253 - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
254 - work around yet another signal race bug, newly introduced by POE. My
255 how that module sucks.
256 - add google public ipv6 dns as fallback servers, so AE::DNS can finally
257 support ipv6-only operation even with defaults (also use ::1 instead
258 of 127.0.0.1).
259 - give better guidelines on how to chose a logging level.
260 - AnyEvent::Log can now cap (limit) log message priority by context.
261 - AE::log will now save and restore $! and $@, so callers don't have to.
262 - AE::Strict now checks that registered fds are still valid at regular
263 intervals.
264 - skip frequently called 'require' calls if the module appears loaded.
265 - increase signal latency test timer considerably for poor little osx,
266 which can't be bothered with basic posix functionality such as signal
267 delivery.
268 - mention some debugging aids in the tutorial.
269 - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
270 - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
271 of the context as title.
272 - AnyEvent::Strict would not restore read-write access to $_ when a callback
273 died - this is a user bug, but since AE::Strict exists to help dbeugging...
274 - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
275 to work with it - the author is well aware of the issues but refuses
276 to fix them. This extreme step has been taken because the module actively
277 attacks the goals of AnyEvent and makes it harder for module authors to use
278 AnyEvent.
279
2806.02 Fri Aug 26 20:08:31 CEST 2011
281 - log_to_syslog now accepts facility strings.
282 - log_to_syslog would not allow facilities - "$facility|$level"
283 *literally* means that string. sheesh.
284 - the CPAN parser got confused and thought we provide Sys::Syslog, try
285 to work around.
286 - renamed AnyEvent::Impl::FLTK2 to FLTK.
287
2886.01 Fri Aug 26 07:04:11 CEST 2011
11 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include 289 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include
12 the TTL as fourth element - this affects ->resolve directly, 290 the TTL as fourth element - this affects ->resolve, ->request
13 and ->request and ->dns_unpack indirectly. Convenience functions 291 and ->dns_unpack indirectly. Convenience functions such as
14 such as AnyEvent::DNS::{a,txt,mx,srv} are not affected. 292 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is
293 AnyEvent::Socket.
15 - INCOMPATIBLE CHANGE: backend authors now should not implement 294 - INCOMPATIBLE CHANGE: backend authors now should not implement
16 one_event or loop, but instead the AnyEvent::CondVar::_wait and _poll 295 one_event or loop, but instead the AnyEvent::CondVar::_wait and _poll
17 methods. 296 methods.
297 - INCOMPATIBLE CHANGE: verbosity levels have been redefined, see
298 AnyEvent (PERL_ANYEVENT_VERBOSE) and AnyEvent::Log for details.

317 - new env variable, PERL_ANYEVENT_HOSTS, to override the place where
318 /etc/hosts can be found.
319 - an empty PERL_ANYEVENT_RESOLV_CONF now selects the default

322 PERL_ANYEVENT_xyz, subject to some rules.
323 - lots of new AnyEvent::Debug functionality.
