6TODO: check for #TODO 20TODO: add some cheta-sheet to log synopsis regarding AE_LOG=AnyEvent::MP=+
7TODO: new context 21TODO: tcp_connect option for AnyEvent::Handle?
8TODO: consume-- 22 - AnyEvent::Loop no longer loads the POSIX module if Time::HiRes
9TODO: ae::log examples 23 has monotonic clock support (suggested by Felipe Gasper).
10TODO: consolide slogging, e.g AnyEvent::Debug 24 - since Net::SSLeay (up to 1.88-1) is _still not ported to openssl 1.1
116.01 25 and many distributions therefore will have a completely broken
26 Net::SSLeay module for the forseeable future, AnyEvent::TLS
27 will now log a warning (that is not seen by default unless you
28 increase log verbosity).
29 - add tlsv1_3 disable switch to AnyEvent::TLS.
30 - add experimental "tls" method support for AnyEvent::TLS.
31 - tls methods were lowercase, but documented to be uppercase.
32 fix documentation.
33
347.17 Wed Sep 18 03:04:49 CEST 2019
35 - work around antique openssl version in RHEL 7 by formatting
36 dh parameters differently (reported by several people).
37 - add t/13_weaken.t.
38
397.16 Fri Jul 19 18:00:21 CEST 2019
40 - add ffdhe group dh parameters from RFC 7919, and use ffdhe3072
41 as new default, instead of schmorp1539.
42 - AnyEvent::Log did not reassess logging status of
43 AnyEvent::Log::logger's when contexts were changed with
44 ->attach/detach/slaves, causing them to not log even though a
45 recent attach should have caused them to log.
46 - added some more logging configuration examples.
47 - mention RFC 8482 in AnyEvent::DNS.
48
497.15 Tue Feb 26 03:07:42 CET 2019
50 - INCOMPATIBLE CHANGE: AnyEvent::Handle's tls_detect documentation gave
51 separate major and minor versions, while code passed only a single
52 value. This version follows the documentation and now passes separate
53 major and minor values.
54 - work around Net::SSLeay not having been ported to openssl 1.1, but many
55 distributions compiling it against openssl 1.1, which unfortunately
56 succeeds and results in a very broken module.
57 - AnyEvent::DNS::dns_unpack now stores the original DNS packet
58 in the __ member, to allow decoding of undecodable resouce records
59 containing compressed domian names.
60 - AnyEvent::Socket::parse_ipv6 would NOT, as advertised, accept ipv4
61 addresses. It now does and converts them to ipv4 mapped addresses.
62 - support CAA records, based on patch by Steve Atkins.
63 - add freenom and cloudflare nameservers as dns fallback.
64 - AnyEvent::Strict would not properly ward against io watchers
65 on files when the handle passed was a file descriptor.
66 - document "internal" variables used by the dns en-/decoder to allow
67 enterprising users to extend them in a semi-official way.
68
697.14 Sat Jun 24 01:44:19 CEST 2017
70 - fix a crash bug in AnyEvent::Handle with openssl 1.1.0 (patched
71 by Paul Howarth and apparently tracked down by Mike McCauley).
72 - AnyEvent::Handle->keepalive was documented (and defined) twice
73 (found by Matt Merhar).
74 - AnyEvent::Socket::tcp_bind/tcp_server would immediately unlink a unix
75 listening socket unless a guard is used. Change this so that no
76 cleanup will be performed unless a guard is used and document this more
77 clearly.
78 - make tcp_bind/tcp_server error messages more regular.
79 - work around latest perl upstream breakage - this time, perl5porters were
80 apparently bullied by a bogus CVE (CVE-2016-1238), and since distros
81 stupidly apply anything that has "security fix" stamped on it, it's likely
82 going to be a problem in practise (and working around it is trivial on
83 windows and unix).
84 - add TCP_FASTOPEN/MSG_FASTOPEN and MSG_NOSIGNAL/MSG_MORE/MSG_DONTWAIT
85 to constants.
86 - update warnings to common::sense 3.74 standards.
87
887.13 Sat Sep 17 04:31:49 CEST 2016
89 - Only call tlsext_host_name for non-empty common names (reported
90 by Maxime Soulé).
91 - log a (single) notice message if SNI is not supported.
92 - upgrade to UTS-46:9.0.0 draft and switch to non-transitional
93 behaviour, beating thunderbird, ie, edge, chrome and safari to it :)
94 (see also https://bugzilla.mozilla.org/show_bug.cgi?id=1218179)
95 - turns out the UTS-46 IDNA testcase failures were indeed bugs in the
96 testcases and the specification and not in the code - the post-9.0.0
97 unicode files have all known problems fixed, so finally the AnyEvent
98 IDNA implementation can pass the full IDNA testsuite - without needing
99 a single fix :)
100 - guarantee (and document) that condvar callbacks will be removed
101 on invocation - important to avoid circular references.
102
1037.12 Wed Jan 27 19:12:26 CET 2016
104 - use common name as hostname for tls connects, if Net::SSLeay
105 supports SNI.
106 - fix documentation of tls_autostart read type in AnyEvent::Handle,
107 analyzed by Felix Ostmann.
108
1097.11 Thu Jul 16 14:36:00 CEST 2015
110 - AnyEvent::Socket::parse_ipv6 could accept malformed ipv6
111 addresses (extra "::" at end and similar cases).
112 - add a more explicit warning to AnyEvent::Handle that it doesn't
113 work on files, people keep getting confused.
114 - new function AnyEvent::Socket::tcp_bind.
115 - new functions AnyEvent::fh_block and AnyEvent::fh_unblock.
116 - aligned ipv6 address formatting with RFC 5952 (by not shortening
117 a single :0: to ::).
118 - added stability canary support.
119
1207.09 Sat May 2 16:38:53 CEST 2015
121 - AnyEvent::Debug called an internal function (AnyEvent::Log::ft)
122 that was renamed to AnyEvent::Log:format_time. uinder its old name
123 (analyzed by Michael Stovenour).
124 - update AnyEvent::DNS fallback resolver addresses:
125 seems google effectively killed most other free dns resolvers,
126 so remove them, but add cable and wireless (ecrc) since it was
127 stable for 20 years or so, official or not, and there should be
128 an alternative to google.
129 - perl5porters broke windows error codes in 5.20, and mapped
130 WSAEWOULDBLOCK on the (different) EWOULDBLOCK error code, and
131 WSAEINPROGRESS into the incompatible ERINPROGRESS code, probably
132 because they were so cool. They probably broke other error codes
133 for no reason, too, but I didn't care for checking, it's too
134 depressing. This version only works around the WSAEWOULDBLOCK
135 issue, because I don't have a nice way to work around the
136 WSAEINPROGRESS bug.
137
1387.08 Wed Dec 10 05:27:17 CET 2014
139 - work around a newly introduced bug in Socket 2.011 (an
140 errornous sun_length check) (analyzed by Maxime Soulé).
141 - AnyEvent::TLS didn't load (but refer to) AnyEvent::Socket
142 (analyzed by Ben Magistro).
143 - AnyEvent::Strict will now confess, not croak. This is in line with
144 it being a development/debugging tool.
145 - work around a number of libglib bugs (debug builds of libglib enforce
146 certain undocumented behaviour patterns such as not being able to
147 remove a child watch source after it has fired, which we will try
148 to emulate to avoid "criticals". what where they thinking...).
149 - mention json security issues in AnyEvent::Handle, now that Douglas
150 Crockford has foolishly and incompatibly changed JSON.
151 - changed default dns resolver "max_outstanding" value from 1 to 10,
152 the latter beinfg the intended value all along
153 (reported by Ilya Chesnokov).
154 - added new "AnyEvent::Impl::UV" interface module to the UV event lib
155 (written by Mike Lowell).
156
1577.07 Tue Dec 17 17:45:02 CET 2013
158 - the documentation for custom tls verify schemes was wrong. make it agree
159 with the code (reported by Maxime Soulé).
160 - added cbor read and write types to AnyEvent::Handle (using CBOR::XS).
161 - work around an API change in openssl that could cause wrong tls connection
162 aborts, likely on windows only (analyzed by sten).
163 - calling AnyEvent->now_update with AnyEvent::Impl::Perl caused an
164 endless loop (reported by Dietrich Rebmann).
165 - add tlsv1_1 and tlsv1_2 protocols to AnyEvent::TLS
166 (patch by Maxime Soulé).
167 - document AnyEvent::Impl::IOAsync::set_loop and
168 $AnyEvent::Impl::IOAsync::LOOP. Though only documented now, this
169 functionality has _always_ been available.
170 - force a toplevel domain name in t/81_hosts.t (analyzed by
171 David Jack Wange Olrik).
172 - document that AnyEvent::Log uses AnyEvent::IO.
173 - warn about AnyEvent::Filesys::Notify performance.
174 - praise the joys of AnyEvent::Fork::*.
175 - time for an =encoding directive.
176 - do no longer use JSON to create a default json coder, use
177 JSON::XS or JSON::PP directly.
178
1797.05 Wed Aug 21 10:38:08 CEST 2013
180 - uts46data.pl couldn't be found due to wrong naming of the file
181 (reported by Fulko Hew).
182 - handle lone \015's properly in AE::Handle's default line read
183 (reported by various people).
184 - untaint ip addresses found in /etc/hosts (patch by José Micó).
185 - the memleak fix in 7.03 caused resolving via /etc/hosts to always
186 fail on first use (reported and testcase by Andrew Whatson).
187 - expose AnyEvent::Log::format_time, and allow users to redefine it.
188 - expose AnyEvent::Log::default_format, and allow redefinition.
189 - expose AnyEvent::Log::fatal_exit, to allow redefinition.
190 - AnyEvent::Debug shell can now run coro shell commands, if available.
191 - t/63* tests were wrongly in MANIFEST.
192 - kernel.org's finger server went MIA, switch to freebsd.org and
193 icculus.org.
194 - clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO
195 to function asynchronously (reported by Daniel Carosone).
196 - hard-disable $^W in most tests, it generates too much garbage output.
197 - use a (hopefully) more future-proof method to emulate common::sense.
198 - upgrade to UTS-46:6.2.0.
199 - switch to INSTLIB from INSTLIBDIR, as INSTLIBDIR was wrongly
200 documented. should not affect anything.
201
2027.04 Thu Nov 15 02:23:58 CET 2012
203 - debugging code left in.
204
2057.03 Thu Nov 15 02:16:11 CET 2012
206 - AnyEvent::Socket::inet_aton did not work when dns resolution was
207 used to find the addresses (analyzed and patch by Maxime Soulé).
208 - fix a memory leak in the /etc/hosts lookup code when hosts don't
209 resolve and are not in hosts (analyzed by sten).
210
2117.02 Tue Aug 14 04:27:58 CEST 2012
212 - AnyEvent::Util::run_cmd could block indefinitely (analyzed and test
213 program by Yorhel).
214 - verified that AnyEvent::Socket follows RFC5952.
215 - try to parse "ADDR#PORT" in addition to "ADDR PORT".
216
2177.01 Sun May 13 01:03:17 CEST 2012
218 - fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but
219 not available, instead of throwing an exception.
220 - use File::Spec to get the tmpdir in t/*, to avoid needless
221 failures on (most, not mine :) windows boxes.
222 - new handle read types: tls_detect and tls_autostart.
223
2247.0 Fri Apr 13 06:33:30 CEST 2012
225 - child watchers are broken in POE 1.352 (also many earlier
226 versions) and there seems to be no way to work around it, as POE
227 itself is inherently racy. Document this regression and add a delay
228 in t/68_poe_03_child.t for the time being.
229 - new module AnyEvent::IO, that is a frontend to either a pure-perl
230 synchronous I/O implementation (AnyEvent::IO::Perl), or to the
231 asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO).
232 - load /etc/hosts only when DNS has no answer.
233 - stat /etc/hosts on every access and reload it if it changed.
234 - load /etc/hosts via AnyEvent::IO - potentially asynchronous.
235 - fix a buggy croak in the dh parameter reading in AnyEvent::TLS.
236 - AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As
237 a side effect, they now use true appending as opposed to libc
238 appending, and the file might not have been opened when the function
239 returns.
240 - the default logging level was not properly documented in a variety of
241 places, this has hopefully been rectified.
242 - updated uts46data.pl for unicode 6.1.0.
243 - made log messages generated by AnyEvent submodules not
244 include the package name anymore, as it will be logged
245 by default already.
246 - upgrade to the trick used by common-sense 3.5 to work
247 around extra warning torture/breakage under perl 5.15.x.
248 - log messages by anyevent are now ucfirst, are usually full
249 sentences and do no longer include the package name.
250 - the storable read type would sometimes throw an exception instead
251 of causing EBADMSG (analyzed by Maxime Soulé).
252 - work around a bug in openssl 1.0.1 which enforces a minimum rsa
253 keysize (reported by Paul Howarth).
254 - documented Rocco fabricating statements about AnyEvent and me.
255
2566.14 Tue Jan 31 20:00:24 CET 2012
257 - AnyEvent::Impl::Tk was broken due to a mysterious "die" inside,
258 probably an editing mistake (reported by Darin McBride).
259
2606.13 Thu Jan 12 07:27:01 CET 2012
261 - AnyEvent::Util::fork_call checked for POSIX availability in the wrong way,
262 causing it to fail if POSIX wasn't loaded already (analysed by Rock Power).
263 - AnyEvent::Handle::push_read (line => did pass $1 directly, so
264 regex-matching inside the callback would change the parameter, despite
265 $1 being dynamically scoped per-block. this perl bug is now being
266 worked around (testcase by Cindy Wang).
267
2686.12 Mon Dec 12 13:21:10 CET 2011
269 - $! was clobbered by subsequent calls in tcp_connect, due to
270 the postpone not saving/restoring it (analyzed by Richard Garnish).
271
2726.11 Tue Nov 22 10:36:05 CET 2011
273 - Tk cannot create windows when tainted unless you set a title, so
274 set a dummy title for AnyEvent's dummy mainwindow. How dummy.
275 - escape any nonprintable/nonascii characters when stringifying
276 backtraces.
277 - log the reason loading an interface module fails to load at level debug.
278
2796.1 Tue Oct 4 19:44:30 CEST 2011
280 - INCOMPATIBLE CHANGE: the default log level is now "4" (error
281 and above), and some messages inside AnyEvent have been elevated
282 to higher log levels to print by default.
283 - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
284 - work around yet another signal race bug, newly introduced by POE. My
285 how that module sucks.
286 - add google public ipv6 dns as fallback servers, so AE::DNS can finally
287 support ipv6-only operation even with defaults (also use ::1 instead
288 of 127.0.0.1).
289 - give better guidelines on how to chose a logging level.
290 - AnyEvent::Log can now cap (limit) log message priority by context.
291 - AE::log will now save and restore $! and $@, so callers don't have to.
292 - AE::Strict now checks that registered fds are still valid at regular
293 intervals.
294 - skip frequently called 'require' calls if the module appears loaded.
295 - increase signal latency test timer considerably for poor little osx,
296 which can't be bothered with basic posix functionality such as signal
297 delivery.
298 - mention some debugging aids in the tutorial.
299 - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
300 - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
301 of the context as title.
302 - AnyEvent::Strict would not restore read-write access to $_ when a callback
303 died - this is a user bug, but since AE::Strict exists to help dbeugging...
304 - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
305 to work with it - the author is well aware of the issues but refuses
306 to fix them. This extreme step has been taken because the module actively
307 attacks the goals of AnyEvent and makes it harder for module authors to use
308 AnyEvent.
309
3106.02 Fri Aug 26 20:08:31 CEST 2011
311 - log_to_syslog now accepts facility strings.
312 - log_to_syslog would not allow facilities - "$facility|$level"
313 *literally* means that string. sheesh.
314 - the CPAN parser got confused and thought we provide Sys::Syslog, try
315 to work around.
316 - renamed AnyEvent::Impl::FLTK2 to FLTK.
317
3186.01 Fri Aug 26 07:04:11 CEST 2011
12 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include 319 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include
13 the TTL as fourth element - this affects ->resolve, ->request 320 the TTL as fourth element - this affects ->resolve, ->request
14 and ->dns_unpack indirectly. Convenience functions such as 321 and ->dns_unpack indirectly. Convenience functions such as
15 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is 322 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is
