217.15 Tue Feb 26 03:07:42 CET 2019
22 - INCOMPATIBLE CHANGE: AnyEvent::Handle's tls_detect documentation gave
23 separate major and minor versions, while code passed only a single
24 value. This version follows the documentation and now passes separate
25 major and minor values.
26 - work around Net::SSLeay not having been ported to openssl 1.1, but many
27 distributions compiling it against openssl 1.1, which unfortunately
28 succeeds and results in a very broken module.
29 - AnyEvent::DNS::dns_unpack now stores the original DNS packet
30 in the __ member, to allow decoding of undecodable resouce records
31 containing compressed domian names.
32 - AnyEvent::Socket::parse_ipv6 would NOT, as advertised, accept ipv4
33 addresses. It now does and converts them to ipv4 mapped addresses.
34 - support CAA records, based on patch by Steve Atkins.
35 - add freenom and cloudflare nameservers as dns fallback.
36 - AnyEvent::Strict would not properly ward against io watchers
37 on files when the handle passed was a file descriptor.
38 - document "internal" variables used by the dns en-/decoder to allow
39 enterprising users to extend them in a semi-official way.
40
417.14 Sat Jun 24 01:44:19 CEST 2017
42 - fix a crash bug in AnyEvent::Handle with openssl 1.1.0 (patched
43 by Paul Howarth and apparently tracked down by Mike McCauley).
44 - AnyEvent::Handle->keepalive was documented (and defined) twice
45 (found by Matt Merhar).
46 - AnyEvent::Socket::tcp_bind/tcp_server would immediately unlink a unix
47 listening socket unless a guard is used. Change this so that no
48 cleanup will be performed unless a guard is used and document this more
49 clearly.
50 - make tcp_bind/tcp_server error messages more regular.
51 - work around latest perl upstream breakage - this time, perl5porters were
52 apparently bullied by a bogus CVE (CVE-2016-1238), and since distros
53 stupidly apply anything that has "security fix" stamped on it, it's likely
54 going to be a problem in practise (and working around it is trivial on
55 windows and unix).
56 - add TCP_FASTOPEN/MSG_FASTOPEN and MSG_NOSIGNAL/MSG_MORE/MSG_DONTWAIT
57 to constants.
58 - update warnings to common::sense 3.74 standards.
59
607.13 Sat Sep 17 04:31:49 CEST 2016
61 - Only call tlsext_host_name for non-empty common names (reported
62 by Maxime Soulé).
63 - log a (single) notice message if SNI is not supported.
64 - upgrade to UTS-46:9.0.0 draft and switch to non-transitional
65 behaviour, beating thunderbird, ie, edge, chrome and safari to it :)
66 (see also https://bugzilla.mozilla.org/show_bug.cgi?id=1218179)
67 - turns out the UTS-46 IDNA testcase failures were indeed bugs in the
68 testcases and the specification and not in the code - the post-9.0.0
69 unicode files have all known problems fixed, so finally the AnyEvent
70 IDNA implementation can pass the full IDNA testsuite - without needing
71 a single fix :)
72 - guarantee (and document) that condvar callbacks will be removed
73 on invocation - important to avoid circular references.
74
757.12 Wed Jan 27 19:12:26 CET 2016
76 - use common name as hostname for tls connects, if Net::SSLeay
77 supports SNI.
78 - fix documentation of tls_autostart read type in AnyEvent::Handle,
79 analyzed by Felix Ostmann.
80
817.11 Thu Jul 16 14:36:00 CEST 2015
82 - AnyEvent::Socket::parse_ipv6 could accept malformed ipv6
83 addresses (extra "::" at end and similar cases).
84 - add a more explicit warning to AnyEvent::Handle that it doesn't
85 work on files, people keep getting confused.
86 - new function AnyEvent::Socket::tcp_bind.
87 - new functions AnyEvent::fh_block and AnyEvent::fh_unblock.
88 - aligned ipv6 address formatting with RFC 5952 (by not shortening
89 a single :0: to ::).
90 - added stability canary support.
91
927.09 Sat May 2 16:38:53 CEST 2015
93 - AnyEvent::Debug called an internal function (AnyEvent::Log::ft)
94 that was renamed to AnyEvent::Log:format_time. uinder its old name
95 (analyzed by Michael Stovenour).
96 - update AnyEvent::DNS fallback resolver addresses:
97 seems google effectively killed most other free dns resolvers,
98 so remove them, but add cable and wireless (ecrc) since it was
99 stable for 20 years or so, official or not, and there should be
100 an alternative to google.
101 - perl5porters broke windows error codes in 5.20, and mapped
102 WSAEWOULDBLOCK on the (different) EWOULDBLOCK error code, and
103 WSAEINPROGRESS into the incompatible ERINPROGRESS code, probably
104 because they were so cool. They probably broke other error codes
105 for no reason, too, but I didn't care for checking, it's too
106 depressing. This version only works around the WSAEWOULDBLOCK
107 issue, because I don't have a nice way to work around the
108 WSAEINPROGRESS bug.
109
1107.08 Wed Dec 10 05:27:17 CET 2014
111 - work around a newly introduced bug in Socket 2.011 (an
112 errornous sun_length check) (analyzed by Maxime Soulé).
113 - AnyEvent::TLS didn't load (but refer to) AnyEvent::Socket
114 (analyzed by Ben Magistro).
115 - AnyEvent::Strict will now confess, not croak. This is in line with
116 it being a development/debugging tool.
117 - work around a number of libglib bugs (debug builds of libglib enforce
118 certain undocumented behaviour patterns such as not being able to
119 remove a child watch source after it has fired, which we will try
120 to emulate to avoid "criticals". what where they thinking...).
121 - mention json security issues in AnyEvent::Handle, now that Douglas
122 Crockford has foolishly and incompatibly changed JSON.
123 - changed default dns resolver "max_outstanding" value from 1 to 10,
124 the latter beinfg the intended value all along
125 (reported by Ilya Chesnokov).
126 - added new "AnyEvent::Impl::UV" interface module to the UV event lib
127 (written by Mike Lowell).
128
1297.07 Tue Dec 17 17:45:02 CET 2013
130 - the documentation for custom tls verify schemes was wrong. make it agree
131 with the code (reported by Maxime Soulé).
132 - added cbor read and write types to AnyEvent::Handle (using CBOR::XS).
133 - work around an API change in openssl that could cause wrong tls connection
134 aborts, likely on windows only (analyzed by sten).
135 - calling AnyEvent->now_update with AnyEvent::Impl::Perl caused an
136 endless loop (reported by Dietrich Rebmann).
137 - add tlsv1_1 and tlsv1_2 protocols to AnyEvent::TLS
138 (patch by Maxime Soulé).
139 - document AnyEvent::Impl::IOAsync::set_loop and
140 $AnyEvent::Impl::IOAsync::LOOP. Though only documented now, this
141 functionality has _always_ been available.
142 - force a toplevel domain name in t/81_hosts.t (analyzed by
143 David Jack Wange Olrik).
144 - document that AnyEvent::Log uses AnyEvent::IO.
145 - warn about AnyEvent::Filesys::Notify performance.
146 - praise the joys of AnyEvent::Fork::*.
147 - time for an =encoding directive.
148 - do no longer use JSON to create a default json coder, use
149 JSON::XS or JSON::PP directly.
150
1517.05 Wed Aug 21 10:38:08 CEST 2013
152 - uts46data.pl couldn't be found due to wrong naming of the file
153 (reported by Fulko Hew).
154 - handle lone \015's properly in AE::Handle's default line read
155 (reported by various people).
156 - untaint ip addresses found in /etc/hosts (patch by José Micó).
157 - the memleak fix in 7.03 caused resolving via /etc/hosts to always
158 fail on first use (reported and testcase by Andrew Whatson).
159 - expose AnyEvent::Log::format_time, and allow users to redefine it.
160 - expose AnyEvent::Log::default_format, and allow redefinition.
161 - expose AnyEvent::Log::fatal_exit, to allow redefinition.
162 - AnyEvent::Debug shell can now run coro shell commands, if available.
163 - t/63* tests were wrongly in MANIFEST.
164 - kernel.org's finger server went MIA, switch to freebsd.org and
165 icculus.org.
166 - clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO
167 to function asynchronously (reported by Daniel Carosone).
168 - hard-disable $^W in most tests, it generates too much garbage output.
169 - use a (hopefully) more future-proof method to emulate common::sense.
170 - upgrade to UTS-46:6.2.0.
171 - switch to INSTLIB from INSTLIBDIR, as INSTLIBDIR was wrongly
172 documented. should not affect anything.
173
1747.04 Thu Nov 15 02:23:58 CET 2012
175 - debugging code left in.
176
1777.03 Thu Nov 15 02:16:11 CET 2012
178 - AnyEvent::Socket::inet_aton did not work when dns resolution was
179 used to find the addresses (analyzed and patch by Maxime Soulé).
180 - fix a memory leak in the /etc/hosts lookup code when hosts don't
181 resolve and are not in hosts (analyzed by sten).
182
1837.02 Tue Aug 14 04:27:58 CEST 2012
184 - AnyEvent::Util::run_cmd could block indefinitely (analyzed and test
185 program by Yorhel).
186 - verified that AnyEvent::Socket follows RFC5952.
187 - try to parse "ADDR#PORT" in addition to "ADDR PORT".
188
1897.01 Sun May 13 01:03:17 CEST 2012
190 - fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but
191 not available, instead of throwing an exception.
192 - use File::Spec to get the tmpdir in t/*, to avoid needless
193 failures on (most, not mine :) windows boxes.
194 - new handle read types: tls_detect and tls_autostart.
195
1967.0 Fri Apr 13 06:33:30 CEST 2012
197 - child watchers are broken in POE 1.352 (also many earlier
198 versions) and there seems to be no way to work around it, as POE
199 itself is inherently racy. Document this regression and add a delay
200 in t/68_poe_03_child.t for the time being.
201 - new module AnyEvent::IO, that is a frontend to either a pure-perl
202 synchronous I/O implementation (AnyEvent::IO::Perl), or to the
203 asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO).
204 - load /etc/hosts only when DNS has no answer.
205 - stat /etc/hosts on every access and reload it if it changed.
206 - load /etc/hosts via AnyEvent::IO - potentially asynchronous.
207 - fix a buggy croak in the dh parameter reading in AnyEvent::TLS.
208 - AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As
209 a side effect, they now use true appending as opposed to libc
210 appending, and the file might not have been opened when the function
211 returns.
212 - the default logging level was not properly documented in a variety of
213 places, this has hopefully been rectified.
214 - updated uts46data.pl for unicode 6.1.0.
215 - made log messages generated by AnyEvent submodules not
216 include the package name anymore, as it will be logged
217 by default already.
218 - upgrade to the trick used by common-sense 3.5 to work
219 around extra warning torture/breakage under perl 5.15.x.
220 - log messages by anyevent are now ucfirst, are usually full
221 sentences and do no longer include the package name.
222 - the storable read type would sometimes throw an exception instead
223 of causing EBADMSG (analyzed by Maxime Soulé).
224 - work around a bug in openssl 1.0.1 which enforces a minimum rsa
225 keysize (reported by Paul Howarth).
226 - documented Rocco fabricating statements about AnyEvent and me.
227
2286.14 Tue Jan 31 20:00:24 CET 2012
229 - AnyEvent::Impl::Tk was broken due to a mysterious "die" inside,
230 probably an editing mistake (reported by Darin McBride).
231
2326.13 Thu Jan 12 07:27:01 CET 2012
233 - AnyEvent::Util::fork_call checked for POSIX availability in the wrong way,
234 causing it to fail if POSIX wasn't loaded already (analysed by Rock Power).
235 - AnyEvent::Handle::push_read (line => did pass $1 directly, so
236 regex-matching inside the callback would change the parameter, despite
237 $1 being dynamically scoped per-block. this perl bug is now being
238 worked around (testcase by Cindy Wang).
239
2406.12 Mon Dec 12 13:21:10 CET 2011
241 - $! was clobbered by subsequent calls in tcp_connect, due to
242 the postpone not saving/restoring it (analyzed by Richard Garnish).
243
2446.11 Tue Nov 22 10:36:05 CET 2011
245 - Tk cannot create windows when tainted unless you set a title, so
246 set a dummy title for AnyEvent's dummy mainwindow. How dummy.
247 - escape any nonprintable/nonascii characters when stringifying
248 backtraces.
249 - log the reason loading an interface module fails to load at level debug.
250
2516.1 Tue Oct 4 19:44:30 CEST 2011
8 - INCOMPATIBLE CHANGE: the default log level is now "3" (critical 252 - INCOMPATIBLE CHANGE: the default log level is now "4" (error
9 and above), and some emssages inside AnyEvent have bene elevated 253 and above), and some messages inside AnyEvent have been elevated
10 to critical, so. 254 to higher log levels to print by default.
255 - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
256 - work around yet another signal race bug, newly introduced by POE. My
257 how that module sucks.
258 - add google public ipv6 dns as fallback servers, so AE::DNS can finally
259 support ipv6-only operation even with defaults (also use ::1 instead
260 of 127.0.0.1).
11 - give guidelines on how to chose a logging level. 261 - give better guidelines on how to chose a logging level.
262 - AnyEvent::Log can now cap (limit) log message priority by context.
263 - AE::log will now save and restore $! and $@, so callers don't have to.
264 - AE::Strict now checks that registered fds are still valid at regular
265 intervals.
266 - skip frequently called 'require' calls if the module appears loaded.
12 - increase signal latency test timer considerably for poor little osx. 267 - increase signal latency test timer considerably for poor little osx,
268 which can't be bothered with basic posix functionality such as signal
269 delivery.
13 - mention some debugging aids in the tutorial. 270 - mention some debugging aids in the tutorial.
271 - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
272 - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
273 of the context as title.
274 - AnyEvent::Strict would not restore read-write access to $_ when a callback
275 died - this is a user bug, but since AE::Strict exists to help dbeugging...
276 - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
277 to work with it - the author is well aware of the issues but refuses
278 to fix them. This extreme step has been taken because the module actively
279 attacks the goals of AnyEvent and makes it harder for module authors to use
280 AnyEvent.
