23 - AnyEvent::Loop no longer loads the POSIX module if Time::HiRes
24 has monotonic clock support (suggested by Felipe Gasper).
25 - since Net::SSLeay (up to 1.88-1) is _still not ported to openssl 1.1
26 and many distributions therefore will have a completely broken
27 Net::SSLeay module for the forseeable future, AnyEvent::TLS
28 will now log a warning (that is not seen by default unless you
29 increase log verbosity).
30 - add tlsv1_3 disable switch to AnyEvent::TLS.
31 - add experimental "tls" method support for AnyEvent::TLS.
32 - tls methods were lowercase, but documented to be uppercase.
33 fix documentation.
34 - EV backend now uses EV::break when waiting for condvars,
35 making waiting for condvars more efficient. This might
36 "break" already-broken programs that recursively enter
37 the event loop even more.
38
397.17 Wed Sep 18 03:04:49 CEST 2019
40 - work around antique openssl version in RHEL 7 by formatting
41 dh parameters differently (reported by several people).
42 - add t/13_weaken.t.
43
447.16 Fri Jul 19 18:00:21 CEST 2019
45 - add ffdhe group dh parameters from RFC 7919, and use ffdhe3072
46 as new default, instead of schmorp1539.
47 - AnyEvent::Log did not reassess logging status of
48 AnyEvent::Log::logger's when contexts were changed with
49 ->attach/detach/slaves, causing them to not log even though a
50 recent attach should have caused them to log.
51 - added some more logging configuration examples.
52 - mention RFC 8482 in AnyEvent::DNS.
53
547.15 Tue Feb 26 03:07:42 CET 2019
55 - INCOMPATIBLE CHANGE: AnyEvent::Handle's tls_detect documentation gave
56 separate major and minor versions, while code passed only a single
57 value. This version follows the documentation and now passes separate
58 major and minor values.
59 - work around Net::SSLeay not having been ported to openssl 1.1, but many
60 distributions compiling it against openssl 1.1, which unfortunately
61 succeeds and results in a very broken module.
62 - AnyEvent::DNS::dns_unpack now stores the original DNS packet
63 in the __ member, to allow decoding of undecodable resouce records
64 containing compressed domian names.
65 - AnyEvent::Socket::parse_ipv6 would NOT, as advertised, accept ipv4
66 addresses. It now does and converts them to ipv4 mapped addresses.
67 - support CAA records, based on patch by Steve Atkins.
68 - add freenom and cloudflare nameservers as dns fallback.
69 - AnyEvent::Strict would not properly ward against io watchers
70 on files when the handle passed was a file descriptor.
71 - document "internal" variables used by the dns en-/decoder to allow
72 enterprising users to extend them in a semi-official way.
73
747.14 Sat Jun 24 01:44:19 CEST 2017
75 - fix a crash bug in AnyEvent::Handle with openssl 1.1.0 (patched
76 by Paul Howarth and apparently tracked down by Mike McCauley).
77 - AnyEvent::Handle->keepalive was documented (and defined) twice
78 (found by Matt Merhar).
79 - AnyEvent::Socket::tcp_bind/tcp_server would immediately unlink a unix
80 listening socket unless a guard is used. Change this so that no
81 cleanup will be performed unless a guard is used and document this more
82 clearly.
83 - make tcp_bind/tcp_server error messages more regular.
84 - work around latest perl upstream breakage - this time, perl5porters were
85 apparently bullied by a bogus CVE (CVE-2016-1238), and since distros
86 stupidly apply anything that has "security fix" stamped on it, it's likely
87 going to be a problem in practise (and working around it is trivial on
88 windows and unix).
89 - add TCP_FASTOPEN/MSG_FASTOPEN and MSG_NOSIGNAL/MSG_MORE/MSG_DONTWAIT
90 to constants.
91 - update warnings to common::sense 3.74 standards.
92
937.13 Sat Sep 17 04:31:49 CEST 2016
94 - Only call tlsext_host_name for non-empty common names (reported
95 by Maxime Soulé).
96 - log a (single) notice message if SNI is not supported.
97 - upgrade to UTS-46:9.0.0 draft and switch to non-transitional
98 behaviour, beating thunderbird, ie, edge, chrome and safari to it :)
99 (see also https://bugzilla.mozilla.org/show_bug.cgi?id=1218179)
100 - turns out the UTS-46 IDNA testcase failures were indeed bugs in the
101 testcases and the specification and not in the code - the post-9.0.0
102 unicode files have all known problems fixed, so finally the AnyEvent
103 IDNA implementation can pass the full IDNA testsuite - without needing
104 a single fix :)
105 - guarantee (and document) that condvar callbacks will be removed
106 on invocation - important to avoid circular references.
107
1087.12 Wed Jan 27 19:12:26 CET 2016
109 - use common name as hostname for tls connects, if Net::SSLeay
110 supports SNI.
111 - fix documentation of tls_autostart read type in AnyEvent::Handle,
112 analyzed by Felix Ostmann.
113
1147.11 Thu Jul 16 14:36:00 CEST 2015
115 - AnyEvent::Socket::parse_ipv6 could accept malformed ipv6
116 addresses (extra "::" at end and similar cases).
117 - add a more explicit warning to AnyEvent::Handle that it doesn't
118 work on files, people keep getting confused.
119 - new function AnyEvent::Socket::tcp_bind.
120 - new functions AnyEvent::fh_block and AnyEvent::fh_unblock.
121 - aligned ipv6 address formatting with RFC 5952 (by not shortening
122 a single :0: to ::).
123 - added stability canary support.
124
1257.09 Sat May 2 16:38:53 CEST 2015
126 - AnyEvent::Debug called an internal function (AnyEvent::Log::ft)
127 that was renamed to AnyEvent::Log:format_time. uinder its old name
128 (analyzed by Michael Stovenour).
129 - update AnyEvent::DNS fallback resolver addresses:
130 seems google effectively killed most other free dns resolvers,
131 so remove them, but add cable and wireless (ecrc) since it was
132 stable for 20 years or so, official or not, and there should be
133 an alternative to google.
134 - perl5porters broke windows error codes in 5.20, and mapped
135 WSAEWOULDBLOCK on the (different) EWOULDBLOCK error code, and
136 WSAEINPROGRESS into the incompatible ERINPROGRESS code, probably
137 because they were so cool. They probably broke other error codes
138 for no reason, too, but I didn't care for checking, it's too
139 depressing. This version only works around the WSAEWOULDBLOCK
140 issue, because I don't have a nice way to work around the
141 WSAEINPROGRESS bug.
142
1437.08 Wed Dec 10 05:27:17 CET 2014
144 - work around a newly introduced bug in Socket 2.011 (an
145 errornous sun_length check) (analyzed by Maxime Soulé).
146 - AnyEvent::TLS didn't load (but refer to) AnyEvent::Socket
147 (analyzed by Ben Magistro).
148 - AnyEvent::Strict will now confess, not croak. This is in line with
149 it being a development/debugging tool.
150 - work around a number of libglib bugs (debug builds of libglib enforce
151 certain undocumented behaviour patterns such as not being able to
152 remove a child watch source after it has fired, which we will try
153 to emulate to avoid "criticals". what where they thinking...).
154 - mention json security issues in AnyEvent::Handle, now that Douglas
155 Crockford has foolishly and incompatibly changed JSON.
156 - changed default dns resolver "max_outstanding" value from 1 to 10,
157 the latter beinfg the intended value all along
158 (reported by Ilya Chesnokov).
159 - added new "AnyEvent::Impl::UV" interface module to the UV event lib
160 (written by Mike Lowell).
161
1627.07 Tue Dec 17 17:45:02 CET 2013
163 - the documentation for custom tls verify schemes was wrong. make it agree
164 with the code (reported by Maxime Soulé).
165 - added cbor read and write types to AnyEvent::Handle (using CBOR::XS).
166 - work around an API change in openssl that could cause wrong tls connection
167 aborts, likely on windows only (analyzed by sten).
168 - calling AnyEvent->now_update with AnyEvent::Impl::Perl caused an
169 endless loop (reported by Dietrich Rebmann).
170 - add tlsv1_1 and tlsv1_2 protocols to AnyEvent::TLS
171 (patch by Maxime Soulé).
172 - document AnyEvent::Impl::IOAsync::set_loop and
173 $AnyEvent::Impl::IOAsync::LOOP. Though only documented now, this
174 functionality has _always_ been available.
175 - force a toplevel domain name in t/81_hosts.t (analyzed by
176 David Jack Wange Olrik).
177 - document that AnyEvent::Log uses AnyEvent::IO.
178 - warn about AnyEvent::Filesys::Notify performance.
179 - praise the joys of AnyEvent::Fork::*.
180 - time for an =encoding directive.
181 - do no longer use JSON to create a default json coder, use
182 JSON::XS or JSON::PP directly.
183
1847.05 Wed Aug 21 10:38:08 CEST 2013
185 - uts46data.pl couldn't be found due to wrong naming of the file
186 (reported by Fulko Hew).
187 - handle lone \015's properly in AE::Handle's default line read
188 (reported by various people).
189 - untaint ip addresses found in /etc/hosts (patch by José Micó).
190 - the memleak fix in 7.03 caused resolving via /etc/hosts to always
191 fail on first use (reported and testcase by Andrew Whatson).
192 - expose AnyEvent::Log::format_time, and allow users to redefine it.
193 - expose AnyEvent::Log::default_format, and allow redefinition.
194 - expose AnyEvent::Log::fatal_exit, to allow redefinition.
195 - AnyEvent::Debug shell can now run coro shell commands, if available.
196 - t/63* tests were wrongly in MANIFEST.
197 - kernel.org's finger server went MIA, switch to freebsd.org and
198 icculus.org.
199 - clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO
200 to function asynchronously (reported by Daniel Carosone).
201 - hard-disable $^W in most tests, it generates too much garbage output.
202 - use a (hopefully) more future-proof method to emulate common::sense.
203 - upgrade to UTS-46:6.2.0.
204 - switch to INSTLIB from INSTLIBDIR, as INSTLIBDIR was wrongly
205 documented. should not affect anything.
206
2077.04 Thu Nov 15 02:23:58 CET 2012
208 - debugging code left in.
209
2107.03 Thu Nov 15 02:16:11 CET 2012
211 - AnyEvent::Socket::inet_aton did not work when dns resolution was
212 used to find the addresses (analyzed and patch by Maxime Soulé).
213 - fix a memory leak in the /etc/hosts lookup code when hosts don't
214 resolve and are not in hosts (analyzed by sten).
215
2167.02 Tue Aug 14 04:27:58 CEST 2012
217 - AnyEvent::Util::run_cmd could block indefinitely (analyzed and test
218 program by Yorhel).
219 - verified that AnyEvent::Socket follows RFC5952.
220 - try to parse "ADDR#PORT" in addition to "ADDR PORT".
221
2227.01 Sun May 13 01:03:17 CEST 2012
223 - fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but
224 not available, instead of throwing an exception.
225 - use File::Spec to get the tmpdir in t/*, to avoid needless
226 failures on (most, not mine :) windows boxes.
227 - new handle read types: tls_detect and tls_autostart.
228
2297.0 Fri Apr 13 06:33:30 CEST 2012
230 - child watchers are broken in POE 1.352 (also many earlier
231 versions) and there seems to be no way to work around it, as POE
232 itself is inherently racy. Document this regression and add a delay
233 in t/68_poe_03_child.t for the time being.
234 - new module AnyEvent::IO, that is a frontend to either a pure-perl
235 synchronous I/O implementation (AnyEvent::IO::Perl), or to the
236 asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO).
237 - load /etc/hosts only when DNS has no answer.
238 - stat /etc/hosts on every access and reload it if it changed.
239 - load /etc/hosts via AnyEvent::IO - potentially asynchronous.
240 - fix a buggy croak in the dh parameter reading in AnyEvent::TLS.
241 - AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As
242 a side effect, they now use true appending as opposed to libc
243 appending, and the file might not have been opened when the function
244 returns.
245 - the default logging level was not properly documented in a variety of
246 places, this has hopefully been rectified.
247 - updated uts46data.pl for unicode 6.1.0.
248 - made log messages generated by AnyEvent submodules not
249 include the package name anymore, as it will be logged
250 by default already.
251 - upgrade to the trick used by common-sense 3.5 to work
252 around extra warning torture/breakage under perl 5.15.x.
253 - log messages by anyevent are now ucfirst, are usually full
254 sentences and do no longer include the package name.
255 - the storable read type would sometimes throw an exception instead
256 of causing EBADMSG (analyzed by Maxime Soulé).
257 - work around a bug in openssl 1.0.1 which enforces a minimum rsa
258 keysize (reported by Paul Howarth).
259 - documented Rocco fabricating statements about AnyEvent and me.
260
2616.14 Tue Jan 31 20:00:24 CET 2012
262 - AnyEvent::Impl::Tk was broken due to a mysterious "die" inside,
263 probably an editing mistake (reported by Darin McBride).
264
2656.13 Thu Jan 12 07:27:01 CET 2012
266 - AnyEvent::Util::fork_call checked for POSIX availability in the wrong way,
267 causing it to fail if POSIX wasn't loaded already (analysed by Rock Power).
268 - AnyEvent::Handle::push_read (line => did pass $1 directly, so
269 regex-matching inside the callback would change the parameter, despite
270 $1 being dynamically scoped per-block. this perl bug is now being
271 worked around (testcase by Cindy Wang).
272
2736.12 Mon Dec 12 13:21:10 CET 2011
274 - $! was clobbered by subsequent calls in tcp_connect, due to
275 the postpone not saving/restoring it (analyzed by Richard Garnish).
276
2776.11 Tue Nov 22 10:36:05 CET 2011
278 - Tk cannot create windows when tainted unless you set a title, so
279 set a dummy title for AnyEvent's dummy mainwindow. How dummy.
280 - escape any nonprintable/nonascii characters when stringifying
281 backtraces.
282 - log the reason loading an interface module fails to load at level debug.
283
2846.1 Tue Oct 4 19:44:30 CEST 2011
285 - INCOMPATIBLE CHANGE: the default log level is now "4" (error
286 and above), and some messages inside AnyEvent have been elevated
287 to higher log levels to print by default.
288 - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
289 - work around yet another signal race bug, newly introduced by POE. My
290 how that module sucks.
291 - add google public ipv6 dns as fallback servers, so AE::DNS can finally
292 support ipv6-only operation even with defaults (also use ::1 instead
293 of 127.0.0.1).
294 - give better guidelines on how to chose a logging level.
295 - AnyEvent::Log can now cap (limit) log message priority by context.
296 - AE::log will now save and restore $! and $@, so callers don't have to.
297 - AE::Strict now checks that registered fds are still valid at regular
298 intervals.
299 - skip frequently called 'require' calls if the module appears loaded.
300 - increase signal latency test timer considerably for poor little osx,
301 which can't be bothered with basic posix functionality such as signal
302 delivery.
303 - mention some debugging aids in the tutorial.
304 - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
305 - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
306 of the context as title.
307 - AnyEvent::Strict would not restore read-write access to $_ when a callback
308 died - this is a user bug, but since AE::Strict exists to help dbeugging...
309 - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
310 to work with it - the author is well aware of the issues but refuses
311 to fix them. This extreme step has been taken because the module actively
312 attacks the goals of AnyEvent and makes it harder for module authors to use
313 AnyEvent.
314
3156.02 Fri Aug 26 20:08:31 CEST 2011
316 - log_to_syslog now accepts facility strings.
317 - log_to_syslog would not allow facilities - "$facility|$level"
318 *literally* means that string. sheesh.
319 - the CPAN parser got confused and thought we provide Sys::Syslog, try
320 to work around.
321 - renamed AnyEvent::Impl::FLTK2 to FLTK.
322
3236.01 Fri Aug 26 07:04:11 CEST 2011
9 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include 324 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include
10 the TTL as fourth element - this affects ->resolve, ->request 325 the TTL as fourth element - this affects ->resolve, ->request
11 and ->dns_unpack indirectly. Convenience functions such as 326 and ->dns_unpack indirectly. Convenience functions such as
12 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is 327 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is
13 AnyEvent::Socket. 328 AnyEvent::Socket.
