34.92 3TODO: document TCP_*** constants
4TODO: add debug/trace logging to some modules
5
6 - escape any nonprintable/nonascii characters when stringifying
7 backtraces.
8
96.1 Tue Oct 4 19:44:30 CEST 2011
10 - INCOMPATIBLE CHANGE: the default log level is now "4" (error
11 and above), and some messages inside AnyEvent have been elevated
12 to higher log levels to print by default.
13 - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
14 - work around yet another signal race bug, newly introduced by POE. My
15 how that module sucks.
16 - add google public ipv6 dns as fallback servers, so AE::DNS can finally
17 support ipv6-only operation even with defaults (also use ::1 instead
18 of 127.0.0.1).
19 - give better guidelines on how to chose a logging level.
20 - AnyEvent::Log can now cap (limit) log message priority by context.
21 - AE::log will now save and restore $! and $@, so callers don't have to.
22 - AE::Strict now checks that registered fds are still valid at regular
23 intervals.
24 - skip frequently called 'require' calls if the module appears loaded.
25 - increase signal latency test timer considerably for poor little osx,
26 which can't be bothered with basic posix functionality such as signal
27 delivery.
28 - mention some debugging aids in the tutorial.
29 - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
30 - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
31 of the context as title.
32 - AnyEvent::Strict would not restore read-write access to $_ when a callback
33 died - this is a user bug, but since AE::Strict exists to help dbeugging...
34 - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
35 to work with it - the author is well aware of the issues but refuses
36 to fix them. This extreme step has been taken because the module actively
37 attacks the goals of AnyEvent and makes it harder for module authors to use
38 AnyEvent.
39
406.02 Fri Aug 26 20:08:31 CEST 2011
41 - log_to_syslog now accepts facility strings.
42 - log_to_syslog would not allow facilities - "$facility|$level"
43 *literally* means that string. sheesh.
44 - the CPAN parser got confused and thought we provide Sys::Syslog, try
45 to work around.
46 - renamed AnyEvent::Impl::FLTK2 to FLTK.
47
486.01 Fri Aug 26 07:04:11 CEST 2011
49 - INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include
50 the TTL as fourth element - this affects ->resolve, ->request
51 and ->dns_unpack indirectly. Convenience functions such as
52 AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is
53 AnyEvent::Socket.
54 - INCOMPATIBLE CHANGE: backend authors now should not implement
55 one_event or loop, but instead the AnyEvent::CondVar::_wait and _poll
56 methods.
57 - INCOMPATIBLE CHANGE: verbosity levels have been redefined, see
58 AnyEvent (PERL_ANYEVENT_VERBOSE) and AnyEvent::Log for details.
59 - DEPRECIATION: please change
60 "use AnyEvent::Impl::Perl" to "use AnyEvent::Loop" and
61 "AnyEvent::Impl::Perl::loop" to "AnyEvent::Loop::run"
62 in your programs, for future compatibility.
63 - *blush* idle watcher emulation was borked.
64 - AnyEvent::Strict now checks the AE::xxx functions as well.
65 - querying too long domain names would barf deep inside AnyEvent::DNS - since
66 this is hard to avoid for applications, AnyEvent:.DNS::request now checks for
67 for too long domain names explicitly and passes an undef to the callback
68 instead (reported by James Bromberger).
69 - make AnyEvent::Util more robust against EINTR (analyzed by Andrew Suffield).
70 - new functions: AnyEvent::postpone, AnyEvent::log.
71 - new module: AnyEvent::Log, for simple logging needs.
72 - new env variable, PERL_ANYEVENT_LOG, for fine-grained logging config.
73 - new env variable, PERL_ANYEVENT_DEBUG_SHELL, to automatically start
74 a debug shell.
75 - new env variable, PERL_ANYEVENT_DEBUG_WRAP, to automatically enable
76 watcher instrumentation/wrapping (see AnyEvent::Debug::wrap).
77 - new env variable, PERL_ANYEVENT_HOSTS, to override the place where
78 /etc/hosts can be found.
79 - an empty PERL_ANYEVENT_RESOLV_CONF now selects the default
80 configuration.
81 - env variables can now be specified using AE_xyz instead of
82 PERL_ANYEVENT_xyz, subject to some rules.
83 - lots of new AnyEvent::Debug functionality.
84 - AnyEvent::Strict now checks for modifications $_ by the callback
85 (by setting it to readonly while executing the callback, if possible).
86 - IO::Async sometimes cancels the wrong timer when you call cancel_timer.
87 Invest extra overhead to work around this peculiar behaviour.
88 - split the pure perl backend into a loop module and an impl
89 module (AnyEvent::Loop and AnyEvent::Impl::Perl).
90 - some read types (regex, netstring, json, storable) could
91 errornously keep an AE::Handle object alive on their own
92 (reported by Mohammad Toossi).
93 - AnyEvent::Socket::resolve_sockaddr and all functions using it now
94 supports /etc/hosts overrides.
95 - add more workarounds around child watcher bugs in IO::Async
96 and (newly introduced) in POE.
97 - use glib child watchers and try to work around its limitations,
98 if possible (based on a patch by Kevin Ryde).
99 - add support for FLTK (fltk2), via AnyEvent::Impl::FLTK2.
100 - many read types in AnyEvent::Handle would malfunction during
101 transitions to TLS because of a "delete $self->{rbuf}".
102 (reported by Gerald Galster).
103 - improve condvar blocking wait performance (probably only noticable
104 with faster backends), also make it easier for event loops that
105 do not support blocking waits.
106 - PERL_ANYEVENT_MODEL now also allows full module names, although
107 the usefulness of this feature is not yet clear.
108 - add tests for all supported event loops, conditional on PERL_ANYEVENT_LOOP_TESTS.
109 - add t/80_ssltext.t.
110 - no longer use AUTOLOAD for the initial loading (for no very good reason).
111 - tcp_server now tries to unlink unix domain sockets when it gets destroyed.
112 - do not run event loop detection multiple times when programs call their cached
113 copies of AnyEvent::detect.
114 - parse_hostport now accepts absolute paths als unix domain sockets.
115 - suppress the idiotic warning inside POE by patching the POE::Kernel
116 run flags instead of asking the user to jump through contortions.
117 - add Task::Weaken as dependency (as recommends only at this time).
118 - replace PF_UNSPEC by 0, for good old minix.
119
1206.0 (not officially released, but was on CPAN for about 15 minutes :/)
121
1225.34 Thu May 12 09:59:41 CEST 2011
123 - AE::TLS didn't support both cert_file and key at the same time,
124 due to some copy&paste bug (reported and analyzed by vti).
125 - improve AE::Handle timeout documentation slightly.
126
1275.33 Mon Feb 7 21:51:41 CET 2011
128 - never appeared on CPAN, for unknown reasons.
129 - AnyEvent::Handle on_connect_error - do not try to destroy a handle
130 object when it's already gone (analyzed by Ryan Bullock).
131 - update idna algorithm(s) to UTS#46 version 6.0.0.
132 - preserve trailing dot in idn_to_ascii - testsuite says to preserve,
133 uts46 says it's an error, and testsuite makes more sense.
134 - remove leading dots in idn_to_ascii - testsuite says to remove,
135 uts46 says it's an error, and testsuite makes more sense.
136 - fixed a bug in idn ignored character processing.
137 - passes the uts46 6.0.0 testsuite except for three cases which
138 apparently are bugs in the testsuite itself.
139 - passes the uts46 6.0.1 testsuite except for eleven cases which
140 apparently are bugs in the testsuite itself.
141
1425.31 Sun Jan 23 11:49:19 CET 2011
143 - work around a POE bug where POE would first poll for new events and
144 invoke handlers BEFORE handling the message queue.
145 - fix parsing of "domain" statement in resolv.conf (Johannes Plunien).
146 - stop_read now does just that in TLS mode. see its
147 documentation for caveats.
148 - update to common::sense 3.4 warning set (some warnings in perl impose
149 an arbitrary 32kb limit on regex matches, which affects
150 AnyEvent::Handle).
151 - AE::Handle had a broken rbuf_max method and missing wbuf_max method.
152 - new experimental AE::Handle::resettls method.
153
1545.3 Fri Dec 31 05:48:13 CET 2010
155 - major IOAsync patch by Paul Evans - 0.33 is required, as the major
156 issues with IO::Async have been solved in that version, including
157 the availabilty of a default loop!
158 - implement new wbuf_max parameter for AnyEvent::Handle.
159 - added Cocoa::EventLoop backend by Daisuke Murase.
160 - the default testsuite now honors PERL_ANYEVENT_MODEL (Paul Evans).
161 - clarify handle on_prepare documentation.
162 - set CLOEXEC flag on parent-side fd's in AnyEvent::Util::run_cmd,
163 to avoid leaking them to any child processes.
164 - try to force files into the arch-dependend lib directory, for the
165 half-"turly obsessive compulsive person"(s) that depend on it.
166
1675.29 Sun Dec 5 10:49:21 CET 2010
168 - convert EV backend to EV 4.00 API (so better upgrade EV too).
169 - AE::Handle: implement dynamic read_size adjustment, add
170 max_read_size parameter, reduce default read_size to 2048.
171 - add some FAQ entries for servers and/or on_eof vs. on_error.
172 - work around OS bugs (cygwin again) when lingering in AE::Handle.
173 - reduce memory usage slightly when connect was used in AE::Handle.
174 - wrok around more segfaults in Tk.
175 - document tls_ctx => undef as valid.
176 - detect WNOHANG value at compiletime.
177 - include some probably linux-only support for building AnyEvent
178 as part of the perl core.
179 - improve compatibility of t/08_idna.t to perl 5.8.
180 - make AnyEvent::Strict truly optional (in case somebody builds a
181 minimal perl...).
182
1835.28 Wed Oct 13 04:14:23 CEST 2010
184 - due to a glitch, AnyEvent's internal getprotobyname wasn't
185 actually used in tcp_server.
186 - implement AnyEvent::CondVar->new method, which was documented but
187 missing.
188 - support autoloading of read types in unshift_read.
189 - AnyEvent::Strict: do the test for invalid fh arguments differently,
190 resulting in more informative error messages.
191 - new AnyEvent::FAQ manpage.
192 - clarify that you can actually call push_read etc. in on_read.
193 - put keys and certs in /tmp, not into the current directory,
194 and document this in the SECURITY CONSIDERATIONS sections
195 of AnyEvent::TLS.
196 - support ";" as resolv.conf comment character in AnyEvent::DNS, as
197 requested by Ron Isaacson.
198 - document $AnyEvent::DNS::RESOLVER variable.
199 - incorporated major typo patches by Abhijit Menon-Sen.
200 - AnyEvent::Handle now croaks when negative timeouts are passed.
201 - add a shitload of TCP_xxx sockopt name constants to AnyEvent::Util,
202 undocumented, but who knows when they might come in handy.
203
2045.271 Tue Jun 8 12:05:46 CEST 2010
205 - backport to perl 5.8.x.
206
2075.27 Sun Jun 6 12:12:05 CEST 2010
208 - postpone differently in AnyEvent::Socket now, as
209 when not, canceling the connection attempt might fail
210 (found by Felix Antonius Wilhelm Ostmann).
211 - explicitly check for non-stream sockets in AE::Handle, too many
212 clueless people fell into the trap of this somehow working.
213 - simplified and reworked the "OTHER MODULES" section.
214 - better/more condvar examples.
215
2165.261 Wed Apr 28 16:13:36 CEST 2010
217 - AF_INET6 was not properly used from Socket6 during configuration
218 time (found by Andy Grundman).
219
2205.26 Mon Apr 12 04:49:35 CEST 2010
221 - don't generate spurious readyness notifications when select
222 returns EINTR in the pure perl backend (analysed and testcase
223 by Bas Denissen).
224 - give same examples in SYNOPSIS sections of AnyEvent and AE.
225 - provider faster implementations for AE::time/now/now_update for
226 EV and Perl backends.
227 - provide faster AE::cv and AE::time implementations for all
228 backends.
229 - no longer support lower/mixed-case signal names (this was
230 never documented nor universally supported).
231 - some more memory ยต-optimisations, and somewhat less messy
232 code to cope with both AnyEvent and AE APIs.
233
2345.251 Sat Mar 13 00:58:21 CET 2010
235 - make test failed if it was run before make install on perl <=
236 5.8.8, and older versions of perl make our live very difficult,
237 so write constants.pl during Makefile.PL time.
238
2395.25 Sat Mar 13 00:23:14 CET 2010
240 - fix a race condition in AnyEvent::Handle that would cause
241 a "bio_read: unsupported method" error (in _another_
242 ssl connection) after user code threw an exception.
243 - added AnyEvent::Handle->destroyed method.
244 - speed up AnyEvent::Socket::format_address and ::format_ipv6.
245 - the AnyEvent::Util::fh_nonblocking function worked only
246 by lucky accident on win32.
247 - smaller and faster AnyEvent::Util::fh_nonblocking.
248 - when the (required!) Time::HiRes module is missing, AnyEvent
249 did not fall back to built-in time properly.
250 - do not load Fcntl at runtime, saving memory and loading time.
251 - precompile a number of constants and use them instead of runtime
252 detection and eval.
253 - free detection code after detection and similar memory optimisations.
254 - Perl backend timer interval best effort drift has been improved
255 (same algorithm as EV).
256 - update unicode idna mapping table.
257
2585.24 Tue Jan 5 11:39:43 CET 2010
259 - cygwin never reports errors from failed connects. 1.5 just gives
260 you continous readyness and EAGAIN, 1.7 is even more broken and
261 just hangs. work around both issues in a cygwin-specific hack.
262 - improve idle watcher documentation slightly.
263
2645.23 Sun Dec 20 23:48:00 CET 2009
265 - support IDNs in resolve_sockaddr, and therefore in tcp_connect.
266 - implement punycode_encode/decode, idn_nameprep,
267 idn_to_ascii and idn_to_unicode operations in AnyEvent::Util.
268 - provide $AE::VERSION.
269 - removed traces of "no strict 'refs'".
270
2715.22 Sat Dec 5 03:51:13 CET 2009
272 - downgrade-or-fail in AnyEvent::Handle::push_write, to
273 diagnose encoding failures earlier and more succinctly.
274 (this works around bugs in perl, throwing away encoding info
275 when passing scalar data to extensions).
276 - add more examples to AnyEvent::Socket manpage.
277 - upgrade internal warning set to the same as common::sense 2.03.
278 - use pack "n/a*" for pre-5.8.9 perl compatibility in AnyEvent::DNS
279 (John Beppu).
280 - AnyEvent::Socket::inet_aton now properly supports ipv6, as documented.
281 - add google public dns servers to fallback server set and make sure
282 we load-balance properly between the three sets. also add all
283 fallback dns servers, not just a random one, to each dns config.
284
2855.21 Thu Nov 19 02:48:47 CET 2009
286 - fix a problem where socket constants were called with parameters
287 (spotted by David Friedland).
288 - fork_call never use'd POSIX (reported by Daisuke Maki).
289 - improve perl 5.6 compatibility further (but it still won't work
290 unless you rip out everything but the core).
291 - prefer Net::DNS::Resolver over ipconfig, if installed, on win32.
292 uses 10MB of RAM, but doesn't open a console window. *sigh*.
293
2945.202 Wed Oct 14 22:35:44 CEST 2009
295 - AnyEvent::DNS would unexpectedly clobber $_ under windows
296 (analysed by Matthias Waldorf).
297 - AnyEvent::Handle::run_cmd can now pass the PID of the
298 newly-created process, which is much less useful than it might
299 sound (based on patch by Yann Kerherve).
300
3015.201 Tue Sep 29 12:09:25 CEST 2009
302 - AnyEvent:Handle::on_starttls/on_stoptls methods were broken
303 (reported by Torsten Foertsch).
304 - common::sense 2.0 could cause tcp_server to throw an exception
305 (analysed by elmex).
306
3075.2 Mon Sep 14 07:04:49 CEST 2009
308 - INCOMPATIBLE CHANGE: do no longer support register_read_type
309 and register_write_type in AnyEvent::Handle, instead support
310 package names (the facility was mostly abused).
311 - implement "packagename-as-read/write type" support in
312 AnyEvent::Handle.
313 - AnyEvent::Handle: new options "keepalive" and "oobinline".
314 - oobinline set by default to avoid security issues.
315 - the pure-perl event loop backend wrongly detected times() fallback
316 support (spotted by Pavel Boldin).
317
3185.12 Tue Sep 1 20:26:50 CEST 2009
319 - be more lenient when parsing resolv.conf files, as some people
320 use hashmarks as comment indicator inside directives (reported
321 by Michael S. Fischer).
322 - use same set of warnings as common::sense 2.0.
323 - fix a potential 32 bit overflow issue due to perl having problems
324 with large hex constants in the Perl backend.
325 - do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS
326 by default.
327 - fix some prototypes.
328 - (optionally) require Async::Interrupt 1.02.
329 - replace opendns fallbacks by verizon/level3 public dns servers.
330
3315.112 Fri Aug 21 13:59:04 CEST 2009
332 - AnyEvent::Handle could cause hard crashes in Net::SSLeay when
333 using starttls with an illegal/uncreatable tls context.
334 - port to broken win32 perls.
335
3365.111 Sun Aug 16 18:44:36 CEST 2009
337 - perl errornously requires sockaddr_un structures returned by the
338 kernel to have a specific length. work around this bug by padding
339 sockaddr_un structures (found to fail on OS X, as perl only uses
340 the correct code for GNU/Linux, but likely to fail on other
341 OSes as well).
342
3435.11 Wed Aug 12 17:49:37 CEST 2009
344 - fixed a bug in run_cmd with input from filename.
345 - create a json coder object when none is given in write direction
346 to reduce dependency on JSON.
347
3485.1 Tue Aug 11 03:17:32 CEST 2009
349 - tcp_connect now reports the correct error in $!, not an unrelated
350 one (was broken since 4.91).
351 - AE::Handle did not properly clear rtimeout/wtimeout watchers
352 when retrying a tcp_connect.
353 - new functions: AnyEvent::Util::run_cmd and close_all_fds_except.
354 - fixed wrong documentation in AE::Socket.
355
3565.01 Mon Aug 10 03:16:32 CEST 2009
357 - last release broke EV child watchers :/.
358
