|
19 | 7.16 Fri Jul 19 18:00:21 CEST 2019 |
|
|
20 | - add ffdhe group dh parameters from RFC 7919, and use ffdhe3072 |
|
|
21 | as new default, instead of schmorp1539. |
|
|
22 | - AnyEvent::Log did not reassess logging status of |
|
|
23 | AnyEvent::Log::logger's when contexts were changed with |
|
|
24 | ->attach/detach/slaves, causing them to not log even though a |
|
|
25 | recent attach should have caused them to log. |
|
|
26 | - added some more logging configuration examples. |
|
|
27 | - mention RFC 8482 in AnyEvent::DNS. |
|
|
28 | |
|
|
29 | 7.15 Tue Feb 26 03:07:42 CET 2019 |
|
|
30 | - INCOMPATIBLE CHANGE: AnyEvent::Handle's tls_detect documentation gave |
|
|
31 | separate major and minor versions, while code passed only a single |
|
|
32 | value. This version follows the documentation and now passes separate |
|
|
33 | major and minor values. |
|
|
34 | - work around Net::SSLeay not having been ported to openssl 1.1, but many |
|
|
35 | distributions compiling it against openssl 1.1, which unfortunately |
|
|
36 | succeeds and results in a very broken module. |
|
|
37 | - AnyEvent::DNS::dns_unpack now stores the original DNS packet |
|
|
38 | in the __ member, to allow decoding of undecodable resouce records |
|
|
39 | containing compressed domian names. |
|
|
40 | - AnyEvent::Socket::parse_ipv6 would NOT, as advertised, accept ipv4 |
|
|
41 | addresses. It now does and converts them to ipv4 mapped addresses. |
|
|
42 | - support CAA records, based on patch by Steve Atkins. |
|
|
43 | - add freenom and cloudflare nameservers as dns fallback. |
|
|
44 | - AnyEvent::Strict would not properly ward against io watchers |
|
|
45 | on files when the handle passed was a file descriptor. |
|
|
46 | - document "internal" variables used by the dns en-/decoder to allow |
|
|
47 | enterprising users to extend them in a semi-official way. |
|
|
48 | |
|
|
49 | 7.14 Sat Jun 24 01:44:19 CEST 2017 |
|
|
50 | - fix a crash bug in AnyEvent::Handle with openssl 1.1.0 (patched |
|
|
51 | by Paul Howarth and apparently tracked down by Mike McCauley). |
|
|
52 | - AnyEvent::Handle->keepalive was documented (and defined) twice |
|
|
53 | (found by Matt Merhar). |
|
|
54 | - AnyEvent::Socket::tcp_bind/tcp_server would immediately unlink a unix |
|
|
55 | listening socket unless a guard is used. Change this so that no |
|
|
56 | cleanup will be performed unless a guard is used and document this more |
|
|
57 | clearly. |
|
|
58 | - make tcp_bind/tcp_server error messages more regular. |
|
|
59 | - work around latest perl upstream breakage - this time, perl5porters were |
|
|
60 | apparently bullied by a bogus CVE (CVE-2016-1238), and since distros |
|
|
61 | stupidly apply anything that has "security fix" stamped on it, it's likely |
|
|
62 | going to be a problem in practise (and working around it is trivial on |
|
|
63 | windows and unix). |
|
|
64 | - add TCP_FASTOPEN/MSG_FASTOPEN and MSG_NOSIGNAL/MSG_MORE/MSG_DONTWAIT |
|
|
65 | to constants. |
|
|
66 | - update warnings to common::sense 3.74 standards. |
|
|
67 | |
|
|
68 | 7.13 Sat Sep 17 04:31:49 CEST 2016 |
|
|
69 | - Only call tlsext_host_name for non-empty common names (reported |
|
|
70 | by Maxime Soulé). |
|
|
71 | - log a (single) notice message if SNI is not supported. |
|
|
72 | - upgrade to UTS-46:9.0.0 draft and switch to non-transitional |
|
|
73 | behaviour, beating thunderbird, ie, edge, chrome and safari to it :) |
|
|
74 | (see also https://bugzilla.mozilla.org/show_bug.cgi?id=1218179) |
|
|
75 | - turns out the UTS-46 IDNA testcase failures were indeed bugs in the |
|
|
76 | testcases and the specification and not in the code - the post-9.0.0 |
|
|
77 | unicode files have all known problems fixed, so finally the AnyEvent |
|
|
78 | IDNA implementation can pass the full IDNA testsuite - without needing |
|
|
79 | a single fix :) |
|
|
80 | - guarantee (and document) that condvar callbacks will be removed |
|
|
81 | on invocation - important to avoid circular references. |
|
|
82 | |
|
|
83 | 7.12 Wed Jan 27 19:12:26 CET 2016 |
|
|
84 | - use common name as hostname for tls connects, if Net::SSLeay |
|
|
85 | supports SNI. |
|
|
86 | - fix documentation of tls_autostart read type in AnyEvent::Handle, |
|
|
87 | analyzed by Felix Ostmann. |
|
|
88 | |
|
|
89 | 7.11 Thu Jul 16 14:36:00 CEST 2015 |
|
|
90 | - AnyEvent::Socket::parse_ipv6 could accept malformed ipv6 |
|
|
91 | addresses (extra "::" at end and similar cases). |
|
|
92 | - add a more explicit warning to AnyEvent::Handle that it doesn't |
|
|
93 | work on files, people keep getting confused. |
|
|
94 | - new function AnyEvent::Socket::tcp_bind. |
|
|
95 | - new functions AnyEvent::fh_block and AnyEvent::fh_unblock. |
|
|
96 | - aligned ipv6 address formatting with RFC 5952 (by not shortening |
|
|
97 | a single :0: to ::). |
|
|
98 | - added stability canary support. |
|
|
99 | |
|
|
100 | 7.09 Sat May 2 16:38:53 CEST 2015 |
|
|
101 | - AnyEvent::Debug called an internal function (AnyEvent::Log::ft) |
|
|
102 | that was renamed to AnyEvent::Log:format_time. uinder its old name |
|
|
103 | (analyzed by Michael Stovenour). |
|
|
104 | - update AnyEvent::DNS fallback resolver addresses: |
|
|
105 | seems google effectively killed most other free dns resolvers, |
|
|
106 | so remove them, but add cable and wireless (ecrc) since it was |
|
|
107 | stable for 20 years or so, official or not, and there should be |
|
|
108 | an alternative to google. |
|
|
109 | - perl5porters broke windows error codes in 5.20, and mapped |
|
|
110 | WSAEWOULDBLOCK on the (different) EWOULDBLOCK error code, and |
|
|
111 | WSAEINPROGRESS into the incompatible ERINPROGRESS code, probably |
|
|
112 | because they were so cool. They probably broke other error codes |
|
|
113 | for no reason, too, but I didn't care for checking, it's too |
|
|
114 | depressing. This version only works around the WSAEWOULDBLOCK |
|
|
115 | issue, because I don't have a nice way to work around the |
|
|
116 | WSAEINPROGRESS bug. |
|
|
117 | |
|
|
118 | 7.08 Wed Dec 10 05:27:17 CET 2014 |
|
|
119 | - work around a newly introduced bug in Socket 2.011 (an |
|
|
120 | errornous sun_length check) (analyzed by Maxime Soulé). |
|
|
121 | - AnyEvent::TLS didn't load (but refer to) AnyEvent::Socket |
|
|
122 | (analyzed by Ben Magistro). |
|
|
123 | - AnyEvent::Strict will now confess, not croak. This is in line with |
|
|
124 | it being a development/debugging tool. |
|
|
125 | - work around a number of libglib bugs (debug builds of libglib enforce |
|
|
126 | certain undocumented behaviour patterns such as not being able to |
|
|
127 | remove a child watch source after it has fired, which we will try |
|
|
128 | to emulate to avoid "criticals". what where they thinking...). |
|
|
129 | - mention json security issues in AnyEvent::Handle, now that Douglas |
|
|
130 | Crockford has foolishly and incompatibly changed JSON. |
|
|
131 | - changed default dns resolver "max_outstanding" value from 1 to 10, |
|
|
132 | the latter beinfg the intended value all along |
|
|
133 | (reported by Ilya Chesnokov). |
|
|
134 | - added new "AnyEvent::Impl::UV" interface module to the UV event lib |
|
|
135 | (written by Mike Lowell). |
|
|
136 | |
|
|
137 | 7.07 Tue Dec 17 17:45:02 CET 2013 |
|
|
138 | - the documentation for custom tls verify schemes was wrong. make it agree |
|
|
139 | with the code (reported by Maxime Soulé). |
|
|
140 | - added cbor read and write types to AnyEvent::Handle (using CBOR::XS). |
|
|
141 | - work around an API change in openssl that could cause wrong tls connection |
|
|
142 | aborts, likely on windows only (analyzed by sten). |
|
|
143 | - calling AnyEvent->now_update with AnyEvent::Impl::Perl caused an |
|
|
144 | endless loop (reported by Dietrich Rebmann). |
|
|
145 | - add tlsv1_1 and tlsv1_2 protocols to AnyEvent::TLS |
|
|
146 | (patch by Maxime Soulé). |
|
|
147 | - document AnyEvent::Impl::IOAsync::set_loop and |
|
|
148 | $AnyEvent::Impl::IOAsync::LOOP. Though only documented now, this |
|
|
149 | functionality has _always_ been available. |
|
|
150 | - force a toplevel domain name in t/81_hosts.t (analyzed by |
|
|
151 | David Jack Wange Olrik). |
|
|
152 | - document that AnyEvent::Log uses AnyEvent::IO. |
|
|
153 | - warn about AnyEvent::Filesys::Notify performance. |
|
|
154 | - praise the joys of AnyEvent::Fork::*. |
|
|
155 | - time for an =encoding directive. |
|
|
156 | - do no longer use JSON to create a default json coder, use |
|
|
157 | JSON::XS or JSON::PP directly. |
|
|
158 | |
|
|
159 | 7.05 Wed Aug 21 10:38:08 CEST 2013 |
|
|
160 | - uts46data.pl couldn't be found due to wrong naming of the file |
|
|
161 | (reported by Fulko Hew). |
|
|
162 | - handle lone \015's properly in AE::Handle's default line read |
|
|
163 | (reported by various people). |
|
|
164 | - untaint ip addresses found in /etc/hosts (patch by José Micó). |
|
|
165 | - the memleak fix in 7.03 caused resolving via /etc/hosts to always |
|
|
166 | fail on first use (reported and testcase by Andrew Whatson). |
|
|
167 | - expose AnyEvent::Log::format_time, and allow users to redefine it. |
|
|
168 | - expose AnyEvent::Log::default_format, and allow redefinition. |
|
|
169 | - expose AnyEvent::Log::fatal_exit, to allow redefinition. |
|
|
170 | - AnyEvent::Debug shell can now run coro shell commands, if available. |
|
|
171 | - t/63* tests were wrongly in MANIFEST. |
|
|
172 | - kernel.org's finger server went MIA, switch to freebsd.org and |
|
|
173 | icculus.org. |
|
|
174 | - clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO |
|
|
175 | to function asynchronously (reported by Daniel Carosone). |
|
|
176 | - hard-disable $^W in most tests, it generates too much garbage output. |
|
|
177 | - use a (hopefully) more future-proof method to emulate common::sense. |
|
|
178 | - upgrade to UTS-46:6.2.0. |
|
|
179 | - switch to INSTLIB from INSTLIBDIR, as INSTLIBDIR was wrongly |
|
|
180 | documented. should not affect anything. |
|
|
181 | |
|
|
182 | 7.04 Thu Nov 15 02:23:58 CET 2012 |
|
|
183 | - debugging code left in. |
|
|
184 | |
|
|
185 | 7.03 Thu Nov 15 02:16:11 CET 2012 |
|
|
186 | - AnyEvent::Socket::inet_aton did not work when dns resolution was |
|
|
187 | used to find the addresses (analyzed and patch by Maxime Soulé). |
|
|
188 | - fix a memory leak in the /etc/hosts lookup code when hosts don't |
|
|
189 | resolve and are not in hosts (analyzed by sten). |
|
|
190 | |
|
|
191 | 7.02 Tue Aug 14 04:27:58 CEST 2012 |
|
|
192 | - AnyEvent::Util::run_cmd could block indefinitely (analyzed and test |
|
|
193 | program by Yorhel). |
|
|
194 | - verified that AnyEvent::Socket follows RFC5952. |
|
|
195 | - try to parse "ADDR#PORT" in addition to "ADDR PORT". |
|
|
196 | |
|
|
197 | 7.01 Sun May 13 01:03:17 CEST 2012 |
|
|
198 | - fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but |
|
|
199 | not available, instead of throwing an exception. |
|
|
200 | - use File::Spec to get the tmpdir in t/*, to avoid needless |
|
|
201 | failures on (most, not mine :) windows boxes. |
|
|
202 | - new handle read types: tls_detect and tls_autostart. |
|
|
203 | |
|
|
204 | 7.0 Fri Apr 13 06:33:30 CEST 2012 |
|
|
205 | - child watchers are broken in POE 1.352 (also many earlier |
|
|
206 | versions) and there seems to be no way to work around it, as POE |
|
|
207 | itself is inherently racy. Document this regression and add a delay |
|
|
208 | in t/68_poe_03_child.t for the time being. |
|
|
209 | - new module AnyEvent::IO, that is a frontend to either a pure-perl |
|
|
210 | synchronous I/O implementation (AnyEvent::IO::Perl), or to the |
|
|
211 | asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO). |
|
|
212 | - load /etc/hosts only when DNS has no answer. |
|
|
213 | - stat /etc/hosts on every access and reload it if it changed. |
|
|
214 | - load /etc/hosts via AnyEvent::IO - potentially asynchronous. |
|
|
215 | - fix a buggy croak in the dh parameter reading in AnyEvent::TLS. |
|
|
216 | - AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As |
|
|
217 | a side effect, they now use true appending as opposed to libc |
|
|
218 | appending, and the file might not have been opened when the function |
|
|
219 | returns. |
|
|
220 | - the default logging level was not properly documented in a variety of |
|
|
221 | places, this has hopefully been rectified. |
|
|
222 | - updated uts46data.pl for unicode 6.1.0. |
|
|
223 | - made log messages generated by AnyEvent submodules not |
|
|
224 | include the package name anymore, as it will be logged |
|
|
225 | by default already. |
|
|
226 | - upgrade to the trick used by common-sense 3.5 to work |
|
|
227 | around extra warning torture/breakage under perl 5.15.x. |
|
|
228 | - log messages by anyevent are now ucfirst, are usually full |
|
|
229 | sentences and do no longer include the package name. |
|
|
230 | - the storable read type would sometimes throw an exception instead |
|
|
231 | of causing EBADMSG (analyzed by Maxime Soulé). |
|
|
232 | - work around a bug in openssl 1.0.1 which enforces a minimum rsa |
|
|
233 | keysize (reported by Paul Howarth). |
|
|
234 | - documented Rocco fabricating statements about AnyEvent and me. |
|
|
235 | |
|
|
236 | 6.14 Tue Jan 31 20:00:24 CET 2012 |
|
|
237 | - AnyEvent::Impl::Tk was broken due to a mysterious "die" inside, |
|
|
238 | probably an editing mistake (reported by Darin McBride). |
|
|
239 | |
|
|
240 | 6.13 Thu Jan 12 07:27:01 CET 2012 |
|
|
241 | - AnyEvent::Util::fork_call checked for POSIX availability in the wrong way, |
|
|
242 | causing it to fail if POSIX wasn't loaded already (analysed by Rock Power). |
|
|
243 | - AnyEvent::Handle::push_read (line => did pass $1 directly, so |
|
|
244 | regex-matching inside the callback would change the parameter, despite |
|
|
245 | $1 being dynamically scoped per-block. this perl bug is now being |
|
|
246 | worked around (testcase by Cindy Wang). |
|
|
247 | |
|
|
248 | 6.12 Mon Dec 12 13:21:10 CET 2011 |
|
|
249 | - $! was clobbered by subsequent calls in tcp_connect, due to |
|
|
250 | the postpone not saving/restoring it (analyzed by Richard Garnish). |
|
|
251 | |
|
|
252 | 6.11 Tue Nov 22 10:36:05 CET 2011 |
|
|
253 | - Tk cannot create windows when tainted unless you set a title, so |
|
|
254 | set a dummy title for AnyEvent's dummy mainwindow. How dummy. |
|
|
255 | - escape any nonprintable/nonascii characters when stringifying |
|
|
256 | backtraces. |
|
|
257 | - log the reason loading an interface module fails to load at level debug. |
|
|
258 | |
|
|
259 | 6.1 Tue Oct 4 19:44:30 CEST 2011 |
|
|
260 | - INCOMPATIBLE CHANGE: the default log level is now "4" (error |
|
|
261 | and above), and some messages inside AnyEvent have been elevated |
|
|
262 | to higher log levels to print by default. |
|
|
263 | - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal. |
|
|
264 | - work around yet another signal race bug, newly introduced by POE. My |
|
|
265 | how that module sucks. |
|
|
266 | - add google public ipv6 dns as fallback servers, so AE::DNS can finally |
|
|
267 | support ipv6-only operation even with defaults (also use ::1 instead |
|
|
268 | of 127.0.0.1). |
|
|
269 | - give better guidelines on how to chose a logging level. |
|
|
270 | - AnyEvent::Log can now cap (limit) log message priority by context. |
|
|
271 | - AE::log will now save and restore $! and $@, so callers don't have to. |
|
|
272 | - AE::Strict now checks that registered fds are still valid at regular |
|
|
273 | intervals. |
|
|
274 | - skip frequently called 'require' calls if the module appears loaded. |
|
|
275 | - increase signal latency test timer considerably for poor little osx, |
|
|
276 | which can't be bothered with basic posix functionality such as signal |
|
|
277 | delivery. |
|
|
278 | - mention some debugging aids in the tutorial. |
|
|
279 | - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY. |
|
|
280 | - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name |
|
|
281 | of the context as title. |
|
|
282 | - AnyEvent::Strict would not restore read-write access to $_ when a callback |
|
|
283 | died - this is a user bug, but since AE::Strict exists to help dbeugging... |
|
|
284 | - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse |
|
|
285 | to work with it - the author is well aware of the issues but refuses |
|
|
286 | to fix them. This extreme step has been taken because the module actively |
|
|
287 | attacks the goals of AnyEvent and makes it harder for module authors to use |
|
|
288 | AnyEvent. |
|
|
289 | |
|
|
290 | 6.02 Fri Aug 26 20:08:31 CEST 2011 |
|
|
291 | - log_to_syslog now accepts facility strings. |
|
|
292 | - log_to_syslog would not allow facilities - "$facility|$level" |
|
|
293 | *literally* means that string. sheesh. |
|
|
294 | - the CPAN parser got confused and thought we provide Sys::Syslog, try |
|
|
295 | to work around. |
|
|
296 | - renamed AnyEvent::Impl::FLTK2 to FLTK. |
|
|
297 | |
|
|
298 | 6.01 Fri Aug 26 07:04:11 CEST 2011 |
6 | - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include |
299 | - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include |
7 | the TTL as fourth element - this affects ->resolve, ->request |
300 | the TTL as fourth element - this affects ->resolve, ->request |
