1Revision history for Perl extension AnyEvent. 1Revision history for Perl extension AnyEvent.
2 2
34.23 3 - don't generate spurious readyness notifications when select
4 returns EINTR in the pure perl backend (analysed and testcase
5 by Bas Denissen).
6
75.251 Sat Mar 13 00:58:21 CET 2010
8 - make test failed if it was run before make install on perl <=
9 5.8.8, and older versions of perl make our live very difficult,
10 so write constants.pl during Makefile.PL time.
11
125.25 Sat Mar 13 00:23:14 CET 2010
13 - fix a race condition in AnyEvent::Handle that would cause
14 a "bio_read: unsupported method" error (in _another_
15 ssl connection) after user code threw an exception.
16 - added AnyEvent::Handle->destroyed method.
17 - speed up AnyEvent::Socket::format_address and ::format_ipv6.
18 - the AnyEvent::Util::fh_nonblocking function worked only
19 by lucky accident on win32.
20 - smaller and faster AnyEvent::Util::fh_nonblocking.
21 - when the (required!) Time::HiRes module is missing, AnyEvent
22 did not fall back to built-in time properly.
23 - do not load Fcntl at runtime, saving memory and loading time.
24 - precompile a number of constants and use them instead of runtime
25 detection and eval.
26 - free detection code after detection and similar memory optimisations.
27 - Perl backend timer interval best effort drift has been improved
28 (same algorithm as EV).
29 - update unicode idna mapping table.
30
315.24 Tue Jan 5 11:39:43 CET 2010
32 - cygwin never reports errors from failed connects. 1.5 just gives
33 you continous readyness and EAGAIN, 1.7 is even more broken and
34 just hangs. work around both issues in a cygwin-specific hack.
35 - improve idle watcher documentation slightly.
36
375.23 Sun Dec 20 23:48:00 CET 2009
38 - support IDNs in resolve_sockaddr, and therefore in tcp_connect.
39 - implement punycode_encode/decode, idn_nameprep,
40 idn_to_ascii and idn_to_unicode operations in AnyEvent::Util.
41 - provide $AE::VERSION.
42 - removed traces of "no strict 'refs'".
43
445.22 Sat Dec 5 03:51:13 CET 2009
45 - downgrade-or-fail in AnyEvent::Handle::push_write, to
46 diagnose encoding failures earlier and more succinctly.
47 (this works around bugs in perl, throwing away encoding info
48 when passing scalar data to extensions).
49 - add more examples to AnyEvent::Socket manpage.
50 - upgrade internal warning set to the same as common::sense 2.03.
51 - use pack "n/a*" for pre-5.8.9 perl compatibility in AnyEvent::DNS
52 (John Beppu).
53 - AnyEvent::Socket::inet_aton now properly supports ipv6, as documented.
54 - add google public dns servers to fallback server set and make sure
55 we load-balance properly between the three sets. also add all
56 fallback dns servers, not just a random one, to each dns config.
57
585.21 Thu Nov 19 02:48:47 CET 2009
59 - fix a problem where socket constants were called with parameters
60 (spotted by David Friedland).
61 - fork_call never use'd POSIX (reported by Daisuke Maki).
62 - improve perl 5.6 compatibility further (but it still won't work
63 unless you rip out everything but the core).
64 - prefer Net::DNS::Resolver over ipconfig, if installed, on win32.
65 uses 10MB of RAM, but doesn't open a console window. *sigh*.
66
675.202 Wed Oct 14 22:35:44 CEST 2009
68 - AnyEvent::DNS would unexpectedly clobber $_ under windows
69 (analysed by Matthias Waldorf).
70 - AnyEvent::Handle::run_cmd can now pass the PID of the
71 newly-created process, which is much less useful than it might
72 sound (based on patch by Yann Kerherve).
73
745.201 Tue Sep 29 12:09:25 CEST 2009
75 - AnyEvent:Handle::on_starttls/on_stoptls methods were broken
76 (reported by Torsten Foertsch).
77 - common::sense 2.0 could cause tcp_server to throw an exception
78 (analysed by elmex).
79
805.2 Mon Sep 14 07:04:49 CEST 2009
81 - INCOMPATIBLE CHANGE: do no longer support register_read_type
82 and register_write_type in AnyEvent::Handle, instead support
83 package names (the facility was mostly abused).
84 - implement "packagename-as-read/write type" support in
85 AnyEvent::Handle.
86 - AnyEvent::Handle: new options "keepalive" and "oobinline".
87 - oobinline set by default to avoid security issues.
88 - the pure-perl event loop backend wrongly detected times() fallback
89 support (spotted by Pavel Boldin).
90
915.12 Tue Sep 1 20:26:50 CEST 2009
92 - be more lenient when parsing resolv.conf files, as some people
93 use hashmarks as comment indicator inside directives (reported
94 by Michael S. Fischer).
95 - use same set of warnings as common::sense 2.0.
96 - fix a potential 32 bit overflow issue due to perl having problems
97 with large hex constants in the Perl backend.
98 - do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS
99 by default.
100 - fix some prototypes.
101 - (optionally) require Async::Interrupt 1.02.
102 - replace opendns fallbacks by verizon/level3 public dns servers.
103
1045.112 Fri Aug 21 13:59:04 CEST 2009
105 - AnyEvent::Handle could cause hard crashes in Net::SSLeay when
106 using starttls with an illegal/uncreatable tls context.
107 - port to broken win32 perls.
108
1095.111 Sun Aug 16 18:44:36 CEST 2009
110 - perl errornously requires sockaddr_un structures returned by the
111 kernel to have a specific length. work around this bug by padding
112 sockaddr_un structures (found to fail on OS X, as perl only uses
113 the correct code for GNU/Linux, but likely to fail on other
114 OSes as well).
115
1165.11 Wed Aug 12 17:49:37 CEST 2009
117 - fixed a bug in run_cmd with input from filename.
118 - create a json coder object when none is given in write direction
119 to reduce dependency on JSON.
120
1215.1 Tue Aug 11 03:17:32 CEST 2009
122 - tcp_connect now reports the correct error in $!, not an unrelated
123 one (was broken since 4.91).
124 - AE::Handle did not properly clear rtimeout/wtimeout watchers
125 when retrying a tcp_connect.
126 - new functions: AnyEvent::Util::run_cmd and close_all_fds_except.
127 - fixed wrong documentation in AE::Socket.
128
1295.01 Mon Aug 10 03:16:32 CEST 2009
130 - last release broke EV child watchers :/.
131
1325.0 Sun Aug 9 17:32:09 CEST 2009
133 - officially introduce and document the AE API.
134 - lowering the timeout at runtime did not have immediate effect
135 in AnyEvent::Handle.
136 - AE::Handle now has separate and independent read and write timeout
137 settings.
138 - probe for Guard module when AnyEvent::Util is loaded, not at
139 runtime (Event doesn't like eval "use" from callbacks, and it avoids
140 exporting the probe function).
141 - Impl::IOAsync's io watchers did not use the filehandle emulation
142 code to work around it's watcher limits.
143 - work around IO::Async's problems with overloaded objects.
144 - try to disable wearnings inside IO::Async, it's just too buggy.
145 - do no longer use Event by default, only EV or Perl, Event is too buggy.
146 - hackishly provide fast AE:: interface when EV or Perl is the backend.
147 - inherit VERSION from AnyEvent::VERSION in most modules.
148
1494.91 Thu Aug 6 15:42:45 CEST 2009
150 - AE::Handle::starttls could get out of sync when the read buffer
151 already contains some TLS handshake.
152 - AE::Handle did not properly free the TLS session, causing bigger
153 memory leaks in Net::SSLeay than expected (reported by toaster).
154 - AE::Socket::tcp_connect will now artificially delay invoking
155 the callback to avoid returning after invoking the callback.
156 - convert many internal watcher uses to AE API.
157
1584.9 Sat Aug 1 11:07:01 CEST 2009
159 - Glib silently fails when registering a timeout with
160 a negative value, so avoid that.
161 - call condvar callback immediately when it is set
162 after the condition is already signalled.
163 - check rbuf_max condition only after trying to consume
164 data.
165 - normalise signal numbers to names when using the ae's
166 signal handling, but do not document this (yet).
167 - pure perl signal emulation did not properly set nonblocking
168 mode on the signal pipe on win32 (this is unlikely to have caused
169 any issues).
170 - new module: AnyEvent::Debug.
171 - AnyEvent::Strict now checks that a signal was specified
172 by name (not name or number).
173 - reduce memory footprint in typical cases by ~50kb by
174 only compiling signal code when necessary.
175 - add AnyEvent::Handle->rbuf_max.
176 - grab the AE namespace for future new API, implement stubs for
177 said future/alternative API.
178 - new function: AnyEvent::Socket::format_hostport.
179
1804.881 Tue Jul 28 12:51:53 CEST 2009
181 - work around a bug in local in pre-5.10 perls, causing
182 AnyEvent::Handle to recurse when it should not
183 (analysed by elmex).
184
1854.88 Tue Jul 28 04:04:37 CEST 2009
186 - re-bless the handle into a dummy package after calling
187 AnyEvent::Handle::destroy, so the user does not need to check
188 for errors after every push_write etc.
189 - do not attempt to run t/02_signals.t on obviously broken
190 platforms.
191
1924.87 Sun Jul 26 02:06:16 CEST 2009
193 - do not attempt to linger when there is no longer a valid fh.
194 - enforce tls mode to be either accept or connect, do not simply
195 segfault in Net::SSLeay.
196 - AnyEvent::Handle can now call tcp_connect itself (new parameters
197 connect, on_prepare, on_connect and on_connect_error). Updated
198 tutorial accordingly.
199 - add AnyEvent::Impl::Irssi backend.
200
2014.86 Mon Jul 20 23:52:29 CEST 2009
202 - since the verbose warning is not enough, explicitly document
203 that versions before 1.33 of Net::SSLeay are not secure.
204 - work around signal handling races in Event and (...) Event::Lib.
205 - try to align signal-race timer to full-second boundaries.
206 - work around Tk not liking negative timeouts.
207 - don't complain of different grades of environmental unfriendlyness
208 in IO::Async.
209
2104.85 Sat Jul 18 06:16:14 CEST 2009
211 - nail the signal race problem in perl once and for all
212 (see $AnyEvent::MAX_SIGNAL_LATENCY).
213 - take advantage of Async::Interrupt if it is available.
214 - load Time::HiRes and Guard modules on demand only.
215 - add optional/recommended modules section to AnyEvent
216 documentation.
217 - reduce memory usage considerably (and reduce startup penalty)
218 by not using "strict", "warnings" and "overload" modules.
219 - work around buggy windows/openbsd perls and provide EBADMSG
220 and EPROTO ourselves when missing.
221 - improve perl 5.6 compatibility of the core event loop.
222 - made Net::SSLeay version 1.33 a soft requirement.
223
2244.83 Fri Jul 17 16:56:26 CEST 2009
225 - implement AnyEvent::Socket::getprotobyname.
226 - AnyEvent::CondVar's will now detect recursive blocking
227 waits and will croak, as too many people fall into
228 this trap.
229 - AnyEvent::Handle will now call ->destroy on itself after
230 executing the on_error callback, instead of doing some
231 half-baked internal shutdown, for fatal errors.
232 - clarify on_eof behaviour w.r.t. the read queue and
233 on_read callbacks.
234 - ignore some possible spurious wake-ups in tcp_connect.
235
2364.82 Sat Jul 11 00:34:55 CEST 2009
237 - POE and Event backends didn't accept some callable objects as
238 callbacks.
239 - use Config module instead of POSIX module to detect signal names
240 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
241 module doesn't even have all POSIX signals :/.
242 - use more workarounds around the many refcnt/corruption bugs in
243 Event::Lib.
244 - work around a race condition in perl's select, causing t/03_child.t
245 to rarely fail.
246
2474.81 Thu Jul 9 10:30:30 CEST 2009
248 - AnyEvent::Handle didn't properly diagnose write errors
249 (it expected -1 from syswrite, how lame... :).
250 - support file descriptors in addition to file handles
251 in AnyEvent->io.
252 - new env variables: PERL_ANYEVENT_RESOLV_CONF,
253 PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
254 and PERL_ANYEVENT_CA_PATH.
255 - provide a sensible synopsis section for AnyEvent::TLS.
256 - add a "supported backends" section to the manpage.
257 - added simple io watcher test to testsuite, using a
258 portable_socketpair.
259 - tried to improve the stability of the Event::Lib backend,
260 YMMV.
261
2624.8 Mon Jul 6 23:45:16 CEST 2009
263 - AnyEvent::DNS did not properly follow CNAME records with
264 uppercase targets.
265 - AnyEvent::DNS would errornously return AAAA records
266 with v4 mapped addresses (a faulty record) as ipv4 addresses,
267 causing AnyEvent::Socket to throw an exception.
268 - added new module AnyEvent::TLS for easier SSL/TLS context
269 creation, with many options including hostname verification,
270 secure default configuration, lots of documentation and,
271 predefined diffie-hellman keys for perfect forward security
272 and much more. get it while it's still fresh!
273 - use AnyEvent::TLS in AnyEvent::Handle for context management.
274 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
275 so AnyEvent::Socket users have smaller memory footprint
276 in the common case.
277 - add AnyEvent::Handle->push_shutdown method.
278 - add an additional error message parameter to AnyEvent::Handle's
279 on_error callback (for TLS, $! is still available).
280 - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
281 - make AnyEvent::Handle more robust against early conenction
282 failures (during new), and return C<undef> in that case
283 from the constructor.
284 - AnyEvent::Handle will now try to load only JSON::XS first,
285 then fall back to JSON.
286 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
287 and because it was documented that way.
288
2894.451 Fri Jul 3 00:28:58 CEST 2009
290 - do not clear rbuf when shutting down an AnyEvent::Handle
291 object - doing so breaks AnyEvent::HTTP.
292
2934.45 Mon Jun 29 22:59:26 CEST 2009
294 - a write error could cause AnyEvent::Handle to create
295 an I/O watcher with an undefined $fh.
296 - special-case mapped ipv4 addresses in both
297 AnyEvent::Socket::format_address and parse_address,
298 to treat them just like ipv4 addresses.
299 - updated and overhauled the AnyEvent::Intro doc.
300 - implement AnyEvent::Socket::format_ipv4/ipv6.
301 - slightly speed up portable_pipe/socketpair.
302 - expand condvar begin/end documentation.
303
3044.42 Fri Jun 26 08:32:18 CEST 2009
305 - preliminary and neccesarily incomplete support for IO::Async.
306 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
307 case it was set to IGNORE, to ensure we can catch child statuses
308 even when the calling env acts stupidly.
309 - updated benchmarks with IO::Async, which performs very well.
310
3114.412 Wed Jun 24 01:35:57 CEST 2009
312 - support an "untaint" attribute for AnyEvent::DNS
313 and set it on the default resolver.
314 - implement and document AnyEvent::Impl::Perl::loop.
315 - remove all anyevent-env variables from %ENV
316 when running in tainted mode.
317 - mention and extend the IO::Lambda benchmark.
318
3194.411 Sun Jun 7 18:48:02 CEST 2009
320 - do not try to use F_SETFD on windows.
321
3224.41 Thu May 14 06:40:11 CEST 2009
323 - work around issues in older perls (5.8.0?) when
324 a signal handler is deleted from the %SIG hash.
325 - use POSIX::_exit in child test, to avoid running
326 destructors.
327 - speed up CHLD handling by relying on SIGCHLD being
328 synchronously delivered, even when we roll our own
329 implementation.
330 - AnyEvent::DNS: add the "dname" resource record name
331 for cosmetic reasons.
332
3334.4 Sun Apr 26 20:12:33 CEST 2009
334 - implemented idle watchers, where applicable.
335 - AnyEvent->time died when Event backend was in use.
336 - fix a memleak in the Tk backend.
337 - sped up Tk timer handling.
338 - clip negative "after" values to 0 in AnyEvent::Impl::Event
339 to avoid spamming out warning messages.
340 - fix Qt timers without interval.
341 - avoid Qt zero-timeout special case, in old libqt's.
342
3434.352 Mon Apr 20 16:31:11 CEST 2009
344 - fix AnyEvent::Strict error messages for child watchers.
345 - fix/update Makefile.PL "recommends" versions.
346 - add AnyEvent->now_update.
347
3484.351 Sat Apr 11 07:56:14 CEST 2009
349 - actually make the signal pipe work under win32.
350 - localise $! in signal handler to avoid changing $!, although
351 perl itself does not seem to save/restore errno either.
352 - set the cloexec flag on the signal pipe (normally set by perl too).
353
3544.35 Fri Mar 27 11:48:20 CET 2009
355 - event models relying on AnyEvent's signal watcher emulation did
356 invoke the callback asynchronously, contradicting documentation
357 and causing signals to get lost (this includes AnyEvent's own
358 event loop). AnyEvent now uses the standard pipe trick to make
359 callback execution synchronous to the event loop.
360 - AnyEvent::Handle didn't free TLS context data on DESTROY
361 (patch by Pavel Shaydo).
362 - work around the ever-incompatibly-changing API of MakeMaker.
363 - document that changing global variables without restoring them
364 is a bad idea in Perl (noted by Adam Rosenstein).
365 - AnyEvent::Strict now barfs if ->io is passed a file.
366
3674.34 Thu Feb 12 18:32:45 CET 2009
368 - separately buffer TLS read data, as otherwise the read queue could
369 deadlock as receiving data is not expected while draining the
370 read queue (which cna only happen with TLS).
371 - raise EBADMSG error on JSON decoding errors.
372 - fix some minor manpage bugs (reported by Maximilian Gaß).
373 - speed up select bitmask parsing quite a bit in the pure perl
374 backend.
375 - use CORE::select instead of just select in AnyEvent::Impl::Perl.
376
3774.331 Tue Jan 6 21:07:25 CET 2009
378 - socketpair fails on many vista machines because vista has
379 completely broken accept/getpeername and getsockname functions,
380 so we provide our own socketpair emulation that kind of works
381 (AnyEvent::Util::portable_pipe).
382 - new function: AnyEvent::Util::portable_socketpair.
383 - take advantage of the Guard module if it exists.
384
3854.33 Fri Nov 21 02:35:40 CET 2008
386 - AnyEvent::Strict did errornously flag a fileno of 0 as
387 illegal.
388 - reduce memory usage and slightly speed up the pure perl backend
389 by only storing the file descriptor, not the file handle.
390 - add missing autocork method to AnyEvent::Handle (reported
391 by Adam Rosenstein).
392 - AnyEvent::DNS->resolve errornously documented an $rcode result
393 argument, but there isn't (spotted by Henrik Krohns).
394 - the naked truth about Tk - it's basically unmaintained.
395
3964.32 Mon Nov 3 22:46:32 CET 2008
397 - fix AnyEvent::Socket::resolve_sockaddr to properly support
398 unix sockets again and choose a proper default for
399 the socket type.
400 - fix call to resolve_sockaddr in tcp_connect.
401
4024.31 Thu Oct 30 04:41:48 CET 2008
403 - implemented AnyEvent::Handle->destroy method.
404 - hint about unexpected effects in TLS mode.
405 - speed up AnyEvent::Impl::Perl by using more arrays
406 instead of hashes without the slightest loss of readability :)
407 - work around a perl argument refcounting bug.
408 - with some perl patches applied, AnyEvent now seems leak-free.
409
4104.3 Fri Oct 3 09:18:43 CEST 2008
411 - AnyEvent will now install a no-op signal handler for SIGPIPE,
412 unless one has been installed already.
413 - warn about not loaidng AnyEvent::Impl::POE early enough
414 (patch by Adam Rosenstein).
415 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
416 - fix a bug in where in SSL connect mode, the
417 client would first wait for some data by the server and
418 otherwise hang. (reported and analysed in an absolutely
419 exemplary manner by Adam Rosenstein).
420 - fix a bug in where SSL EOF would not be treated
421 as stream EOF, putting the connection into a hung state.
422 (reported and analysed in an absolutely exemplary manner by Adam
423 Rosenstein).
424 - fix a potential segfault when the TLS context
425 would go missing in a read callback (e.g. due to stoptls) -
426 Net::SSLeay of course makes no type checking whatsoever.
427 - AnyEvent::Handle will not stop the read watcher in TLS mode.
428 - AnyEvent::Handle->stoptls will send a TLS close notify
429 instead of simply destroying the stream now.
430 - fix a bug where large blocks of data written in TLS mode
431 would not be sent unless triggered by receives.
432 - on_drain will now take the tls write buffer into account.
433 - SSL operations have been streamlined a bit and should be faster
434 now, more to come, though.
435 - added a FAQ section, will document nontrivial issues in there.
436
4374.234 Mon Sep 29 04:08:13 CEST 2008
438 - fix child watcher documentation: only child exits will be reported,
439 no trace events.
440 - mention SIGPIPE in AnyEvent::Handle.
441 - perl backend will now use POSIX::times as monotonic clock
442 when available and the monotonic clock option is not.
443 - run even without Time::HiRes in some cases now, but do not
444 provide sub-second accuracy (all *supported* perl versions have
445 Time::HiRes).
446
4474.233 Fri Aug 22 01:48:05 CEST 2008
448 - fix a bug in the testsuite, causing a hang.
449 - clarified lots of AnyEvent::Handle constructor arguments.
450
4514.232 Thu Aug 21 20:44:25 CEST 2008
452 - fix a bug in AnyEvent::Handle that could cause two fatal error
453 callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
454 (testcase by Leon Brocard).
455 - clarified on_eof/on_error documentation a bit.
456
4574.231 Tue Jul 29 13:12:15 CEST 2008
458 - remove some debugging code left in AnyEvent::Util::fork_call
459 (and no, it's impossible to implement with the broken windows
