1 Revision history for Perl extension AnyEvent.
2
3 4.331 Tue Jan 6 21:07:25 CET 2009
4 - socketpair fails on many vista machines because vista has
5 completely broken accept/getpeername and getsockname functions,
6 so we provide our own socketpair emulation that kind of works
7 (AnyEvent::Util::portable_pipe).
8 - new function: AnyEvent::Util::portable_socketpair.
9 - take advantage of the Guard module if it exists.
10
11 4.33 Fri Nov 21 02:35:40 CET 2008
12 - AnyEvent::Strict did errornously flag a fileno of 0 as
13 illegal.
14 - reduce memory usage and slightly speed up the pure perl backend
15 by only storing the file descriptor, not the file handle.
16 - add missing autocork method to AnyEvent::Handle (reported
17 by Adam Rosenstein).
18 - AnyEvent::DNS->resolve errornously documented an $rcode result
19 argument, but there isn't (spotted by Henrik Krohns).
20 - the naked truth about Tk - it's basically unmaintained.
21
22 4.32 Mon Nov 3 22:46:32 CET 2008
23 - fix AnyEvent::Socket::resolve_sockaddr to properly support
24 unix sockets again and choose a proper default for
25 the socket type.
26 - fix call to resolve_sockaddr in tcp_connect.
27
28 4.31 Thu Oct 30 04:41:48 CET 2008
29 - implemented AnyEvent::Handle->destroy method.
30 - hint about unexpected effects in TLS mode.
31 - speed up AnyEvent::Impl::Perl by using more arrays
32 instead of hashes without the slightest loss of readability :)
33 - work around a perl argument refcounting bug.
34 - with some perl patches applied, AnyEvent now seems leak-free.
35
36 4.3 Fri Oct 3 09:18:43 CEST 2008
37 - AnyEvent will now install a no-op signal handler for SIGPIPE,
38 unless one has been installed already.
39 - warn about not loaidng AnyEvent::Impl::POE early enough
40 (patch by Adam Rosenstein).
41 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
42 - fix a bug in where in SSL connect mode, the
43 client would first wait for some data by the server and
44 otherwise hang. (reported and analyzed in an absolutely
45 exemplary manner by Adam Rosenstein).
46 - fix a bug in where SSL EOF would not be treated
47 as stream EOF, putting the connection into a hung state.
48 (reported and analyzed in an absolutely exemplary manner by Adam
49 Rosenstein).
50 - fix a potential segfault when the TLS context
51 would go missing in a read callback (e.g. due to stoptls) -
52 Net::SSLeay of course makes no type checking whatsoever.
53 - AnyEvent::Handle will not stop the read watcher in TLS mode.
54 - AnyEvent::Handle->stoptls will send a TLS close notify
55 instead of simply destroying the stream now.
56 - fix a bug where large blocks of data written in TLS mode
57 would not be sent unless triggered by receives.
58 - on_drain will now take the tls write buffer into account.
59 - SSL operations have been streamlined a bit and should be faster
60 now, more to come, though.
61 - added a FAQ section, will document nontrivial issues in there.
62
63 4.234 Mon Sep 29 04:08:13 CEST 2008
64 - fix child watcher documentation: only child exits will be reported,
65 no trace events.
66 - mention SIGPIPE in AnyEvent::Handle.
67 - perl backend will now use POSIX::times as monotonic clock
68 when available and the monotonic clock option is not.
69 - run even without Time::HiRes in some cases now, but do not
70 provide sub-second accuracy (all *supported* perl versions have
71 Time::HiRes).
72
73 4.233 Fri Aug 22 01:48:05 CEST 2008
74 - fix a bug in the testsuite, causing a hang.
75 - clarified lots of AnyEvent::Handle constructor arguments.
76
77 4.232 Thu Aug 21 20:44:25 CEST 2008
78 - fix a bug in AnyEvent::Handle that could cause two fatal error
79 callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
80 (testcase by Leon Brocard).
81 - clarified on_eof/on_error documentation a bit.
82
83 4.231 Tue Jul 29 13:12:15 CEST 2008
84 - remove some debugging code left in AnyEvent::Util::fork_call
85 (and no, it's impossible to implement with the broken windows
86 perls without resource leaks or worse).
87
88 4.23 Tue Jul 29 12:19:59 CEST 2008
89 - document the first parameter passed to condvar callbacks to be
90 the callback.
91 - add AnyEvent::Socket::{ntoa,aton} aliases.
92 - optimize the AE::Handle->push_read (line) for the default
93 eol marker.
94 - optimize push_read (packstring|storable) for small packets.
95 - invoke on_error callback when no on_eof callback is set.
96 - fix a bug in push_read (storable) of unknown impact.
97
98 4.22 Sun Jul 20 16:34:13 CEST 2008
99 - new function AnyEvent::Socket::parse_hostport.
100 - as the bulkheads at microsoft can't even get getprotobyname reliably
101 working on their shitty fucking broken os we need to hardcode
102 some common protocol numbers in AnyEvent::Socket. How can
103 people even bother with such a pile of shit as windows.
104
105 4.21 Thu Jul 17 14:40:05 CEST 2008
106 - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
107 which is incompatible to previous invocation syntax.
108 - work around more windows perl bugs in fork_call. I cannot imagine
109 why anybody would bother implementing fork in such an obviously
110 unusable way.
111 - avoid calling $do_retry if the request has already finished in
112 AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
113 K. Sharifulin).
114
115 4.2 Sat Jul 12 22:42:11 CEST 2008
116 - support an "interval" argument for repeating timers.
117 - fix a bug in the pure perl event loop that caused timers to
118 be delayed under some circumstances.
119 - implement optional argument checking via PERL_ANYEVENT_STRICT.
120 - not importing anything from Event causes it to malfunction
121 and not use Time::HiRes, work around this bug.
122 - more bug workarounds against the endlessly broken Tk module,
123 seems to work now on 32 bit machines, but less so on 64 bit.
124 - minor optimisations applied to most backends.
125
126 4.161 Fri Jul 4 14:24:48 CEST 2008
127 - fixed the t/handle/02_write.t, it read after write, with the
128 assumption that all data could be written before read
129 (reported by Jim Razmus).
130
131 4.160 Thu Jul 3 04:02:21 CEST 2008
132 - re-registering signal watchers after unregistering one did
133 not work if a backend falls back on AnyEvent's default
134 implementation (also affected child watchers).
135 - new AnyEvent::Handle options: autocork and no_delay.
136
137 4.152 Sun Jun 22 14:15:44 CEST 2008
138 - allow for 32-bit perls that implement shifts differently
139 on different architectures in parse_ipv4 (reported and
140 analysed by Keiichi DAIBA).
141
142 4.151 Fri Jun 6 17:34:24 CEST 2008
143 - make sure specifying _only_ on_read and never pushing reads
144 works.
145
146 4.15 Fri Jun 6 13:00:46 CEST 2008
147 - the pure perl backend would keep some watchers alive when more than
148 one watcher was registered for the same fd.
149 - new "packstring" and "storable" read and write types
150 for AnyEvent::Handle.
151 - allow on_eof handler to be called after on_error with EPIPE returns.
152 - do not immediately call on_read callback in handle constructor.
153
154 4.14 Thu Jun 5 20:29:31 CEST 2008
155 - Fixed a bug in DNS SRV priority sorting.
156 - AnyEvent::Util::guard now reports runtime errors while
157 executing the guard block as warnings.
158 - handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.
159
160 4.13 Thu Jun 5 00:47:59 CEST 2008
161 - AnyEvent::DNS only followed cname chains with length 2,
162 contrary to documentation. bumped it up to 10, thanks to
163 microsoft, the current broken-dns-config-king.
164 - AnyEvent::DNS didn't check for socket return status
165 but instead relied on perl not creating filehandles in that
166 case - too bad it gives you a bogus file handle (reported
167 and analysed by Vladimir Timofeev).
168 - fix queue management logic in AnyEvent::Handle:
169 when on_read was registered, the queue was empty
170 and no progress could be made AnyEvent::Handle would
171 enter an endless loop.
172 - correctly start reading again when the handle became
173 busy again after idling.
174 - correctly treat tls shut-downs as EOF condition
175 (for the time being, would be nice to have a callback for that).
176 - correctly call eof callback under all conditions
177 (hopefully).
178 - the timeout callback did not expect that $self can go
179 away any time.
180
181 4.12 Tue Jun 3 10:58:04 CEST 2008
182 - include AnyEvent::Intro, a tutorial for anyevent,
183 anyevent::socket and anyevent::handle.
184 - allow more options in on_error.
185
186 4.11 Fri May 30 23:42:25 CEST 2008
187 - INCOMPATIBLE CHANGE: replace ptr by real PTR lookup, provide
188 reverse_lookup and reverse_verify to replace it, support
189 v4mapped and v4compat addresses.
190 - provide more documentation for the resolver class.
191 - really replace longest run of :0: by :: in format_address,
192 also properly convert :: and ::1 again.
193 - support NAPTR record name and decode it.
194 - implement random weight sampling for SRV records, as per
195 rfc 2782.
196 - correctly abort on srv-record targets of ".".
197 - added AnyEvent::DNS::wait_for_slot.
198 - in the unlikely event of a virtual circuit connection
199 being invalidated by a delayed udp reply, AnyEvent::DNS
200 could die. this has been fixed.
201 - plug a probable memleak in the DNS vc code.
202 - use configured timeout also for VC request phase.
203 - implement timeout and max_outstanding methods
204 for resolver class.
205 - update version numbers in all modules.
206
207 4.1 Thu May 29 05:45:40 CEST 2008
208 - INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address
209 which mirrors their purpose better (old names still available
210 for a while). Also moved AnyEvent::DNS::addr to
211 AnyEvent::Socket::resolve_sockaddr.
212 - implement AnyEvent->time and AnyEvent->now.
213 - fix IPv6 support in pack_sockaddr.
214 - officially un-experimentalise all newly introduced code.
215 - support unix domain sockets everywhere by specifying
216 a host of "unix/" and the pathname as service.
217 - implement an activity timeout in AnyEvent::Handle.
218 - added a regex read type to AnyEvent::Handle.
219 - added a json read/write type to AnyEvent::Handle.
220 - always croak in on_error in AnyEvent::Handle.
221 - document how to subclass AnyEvent::Handle.
222 - implement AnyEvent::Util::fork_call.
223 - add support for IPv6 nameservers and nameserver statements.
224 - work around _yet_ _another_ windows perl bug in where empty
225 select masks cause errors in the pure perl backend (this
226 workaround cannot be implemented for the other event loops,
227 but EV also works around this).
228 - supply AnyEvent::Socket::address_type and make good use of it.
229 - clarify and fix the Handle documentation w.r.t $self vs. $handle
230 vs. callback arguments.
231 - add some recommends to the META.yml.
232
233 4.05 Mon May 26 19:44:06 CEST 2008
234 - some platforms ignore the rfc and prepend an extra sa_len member to
235 the sockaddr structure, cater for those. also use sockaddr_family,
236 didn't know it was there, but comes in handy for the workaround.
237 - undo the import WIN32 hack.
238
239 4.04 Mon May 26 08:03:31 CEST 2008
240 - try to work around yet another windows bug: failed connects are reported
241 as if it were out-of-band data. windows users: you suck. Only
242 EV, Glib, Event and the pure perl backend can handle this condition.
243 - optimize write algorithm in AnyEvent::Handle.
244 - properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
245 - tcp_connect now properly iterates through all targets.
246 - check wether IPv6 sockets can actually be created, otherwise, disable ipv6
247 support entirely. also hardcode some AF_INET6 constants for the
248 sake of perl 5.8.
249 - vastly improved nameserver/suffix detection algorithm for windows
250 (still a hack...)
251 - try to use a fallback dns server if no dns servers could be found.
252 - splatter around some local $SIG{__DIE__}'s to work around bad
253 die handlers.
254
255 4.03 Sun May 25 05:05:57 CEST 2008
256 - work around perl bugs on windows, where perl returns undocumented
257 error codes for sysread, syswrite etc.
258 - fix AnyEvent::Handle::unshift_read to really unshift and not push.
259 - AnyEvent::Handle could sometimes stumble over 0-byte writes.
260 - fix unpack_sockaddr, now works for AF_INET6 sockaddr's.
261 - updated documentation.
262 - lots of workarounds for perl 5.8 quirks.
263 - implement a more flexible type system for both reads and writes
264 in AnyEvent::Handle.
265 - support IPv6 in tcp_server.
266 - pass local hostname and port to the prepare callback in tcp_server.
267 - make types extendable in AnyEvent::Handle.
268 - croak, not die, in AnyEvent::Handle;
269
270 4.0 Sat May 24 19:58:08 CEST 2008
271 - added (experimental) AnyEvent::DNS module.
272 - added (experimental) AnyEvent::Socket module.
273 - added (experiemntal) support for TLS/SSL in AnyEvent::Handle.
274 - make condvar->end call ->send as documented.
275 - make condvar constructor support the documented cb => argument.
276 - overload condvars so you can use them instead of code references.
277 - support more of the POSIX forms instead of a pure dotted quad for
278 verbatim ip addresses.
279 - AnyEvent::Socket::inet_aton will use AnyEvent::DNS now and not fork anymore.
280 - try very hard not to freeze on broken windows perls.
281 - make on_eof optional in AnyEvent::Handle.
282 - support service names in tcp_connect and tcp_server.
283 - work around netbsd/openbsd bug causing unix sockets not to
284 become writable until empty.
285 - only make a dummy read for error detection when getpeername
286 returns ENOTCONN.
287 - defend AnyEvent::Util::inet_aton against Coro::LWP's brutal
288 override.
289 - new AnyEvent::Guard::cancel.
290
291 3.5 Sat May 17 23:17:14 CEST 2008
292 - gracefully deal with systems not defining CLOCK_MONOTONIC
293 (as opposed to not supporting the clock itself, which worked in 3.41).
294 - added AnyEvent::Util::tcp_connect and AnyEvent::Util::tcp_server
295 helpers, to replace the ill-designed AnyEvent::Socket class.
296 - added some examples (eg/connect, eg/handle).
297 - added AnyEvent::Util::guard.
298 - AnyEvent::Util now exports most of its functions.
299 - fixed a bug in *_read_chunk, where the callback was called with $self as
300 first and second argument.
301 - simplified and fixed regex handling in AnyEvent::Handle::*_read_line.
302 - fix manpage condvars examples to use new syntax.
303 - considerably improve inet_aton with EV::ADNS backend to support
304 cname chains (common dns configuration bug, e.g. with www.google.de)
305 and aaaa records if no a record could be found.
306
307 3.41 Sun May 11 19:53:13 CEST 2008
308 - work around a bug in perl 5.8.8's local. Reported by Yi Ma Mao.
309
310 3.4 Sun May 11 00:29:25 CEST 2008
311 - complete re-implementation of condvars with a hopefully much more useful
312 API (backward compatible functions exist but are undocumented).
313 - AnyEvent::Handle fully rewritten with a hopefully more powerful API
314 (still subject to change).
315 - take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl.
316 - provide AnyEvent::post_detect and @AnyEvent::post_detect, which
317 allows module authors to avoid forcing event loop detection.
318 (used by Coro::AIO, Coro::BDB, Coro::AnyEvent for example).
319 - remove coro backends: Coro now provides generic support for AnyEvent
320 via Coro::AnyEvent.
321
322 3.3 Mon Apr 28 09:51:06 CEST 2008
323 - added AnyEvent::Handle, AnyEvent::Socket and AnyEvent::Util modules.
324 - fix a bug in the pure perl backend that kept watchers alive
325 when multiple watchers were registered for the same fh/poll combo.
326 - add a benchmark section showing AnyEvent overhead and comparing
327 the different event loops with each other.
328 - prefer pure perl over tk when autoprobing, as it's about as fast,
329 but doesn't crash with many watchers.
330 - declare Qt support non-experimental.
331 - clarify the confusing section about the file descriptor being
332 kept alive.
333 - document the race between loading of an event module and
334 child processes exiting.
335 - support POE as "backend" (with some caveats, POE is not generic
336 enough, and darn slow).
337 - support Wx and Prima through POE.
338 - optimise perl backend to use 20% less memory and take advantage
339 of typical timeout behaviour. It can now compete with
340 select/poll-based C event loops in most cases (it is usually
341 faster than Event and Glib :).
342 - roughly cut EV memory use in half and increase its speed by 30%,
343 by removing undocumented functionality. Did something similar
344 to other event loops where possible.
345
346 3.2 Thu Apr 24 10:10:40 CEST 2008
347 - do not die when anyevent watchers are destroyed while running callbacks
348 in the pureperl backend (could only happen when two watchers are registered
349 for the same fh/poll combo).
350 - support autoloading for child watchers, was broken in all versions.
351 - implement PERL_ANYEVENT_MODEL env variable.
352 - (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
353 - (experimental) implement interface to the Qt module (cannot be autoprobed).
354 - this release is IO:AnyEvent-proof.
355
356 3.12 Tue Apr 22 07:11:46 CEST 2008
357 - reinstate AUTHOR section that got lost somehow.
358 - do not hang in the testsuite with badly broken perls (activestate,
359 strawberry...), but instead diagnose the problem and continue.
360 - use INT instead of CHLD in an attempt to support broken windows perls
361 better (this decreases the test quality, unfortunately).
362 - do not send the signal to the process group
363 (no problem for CHLD, bad for INT :).
364
365 3.11 Sat Apr 19 06:57:31 CEST 2008
366 - major documentation rework.
367 - document the fact that child watchers only watch for zombies.
368 - fix the child watcher example.
369
370 3.1 Wed Apr 16 17:09:01 CEST 2008
371 - work around recurring bugs in Tk by dup'ing filehandles, the
372 only method with good success chances on Tk (the bugs apparently
373 don't get fixed anytime soon).
374 - lift the restriction of only one watcher per fh direction
375 (as the Tk bug workaround also lifts it and only Tk imposed
376 such strong limits).
377 - changed probe order to prefer coro adaptors.
378 - explain why recursion into the event loop is not supported
379 unless the backend supports it (only Coro::EV does without
380 any restrictions...).
381 - add simple manpages for all backend modules.
382
383 3.0 Mon Apr 7 21:30:23 CEST 2008
384 - Coro::Signal changed semantics, roll our own, also cleaning
385 up the Coro implementation in general.
386 - rename Coro backend to CoroEvent.
387 - add some decision helping paragraph to the manpage that should
388 help people to decide whether AnyEvent is the right thing for them.
389
390 2.9 Mon Jan 28 13:31:54 CET 2008
391 - update for EV 3.0 API changes.
392
393 2.8 Sun Nov 25 15:06:03 CET 2007
394 - waitpid can validly return 0. accept this fact of life
395 instead of reporting it to any watchers.
396
397 2.7 Fri Nov 23 11:41:14 CET 2007
398 - force use of AnyEvent::Impl::Perl in testsuite, there is
399 too much breakage outside AnyEvent.
400 - deliver signals synchronously in AnyEvent::Impl::Perl
401 or any other event loop that relies on AnyEvents child
402 watcher emulation. *Could* help with hanging testsuite
403 (except when Event or EV are installed).
404
405 2.6 Fri Nov 9 20:36:35 CET 2007
406 - fix bug in testsuite.
407 - move EV adaptor modules to AnyEvent.
408 - add Coro+EV adaptor module.
409
410 2.55 Tue Nov 6 17:41:32 CET 2007
411 - add EV to the list of supported event models.
412 - do not auto-reset pid watchers, pass pid and status to them.
413 - allow a pid of zero to watch for all children in child watchers.
414
415 2.54 Wed Jul 18 17:36:23 CEST 2007
416 - work around a perl bug that results in
417 BEGIN not safe after errors--compilation aborted without
418 any discernible reason or error message by once
419 again not use'ing strict.
420
421 2.53 Sun Jul 8 10:51:53 CEST 2007
422 - make Glib interface work again (spotted by elmex).
423
424 2.52 Wed Mar 7 18:36:16 CET 2007
425 - child watchers stopped working permanently when
426 all current child watchers were destroyed.
427
428 2.51 Mon Dec 11 21:33:24 CET 2006
429 - work around bugs in perl where eval "require Module" returns
430 true even if the module couldn't be loaded :/.
431
432 2.5 Mon Dec 11 02:15:28 CET 2006
433 - avoid $AUTOLOAD because many perls corrupt it.
434 - AnyEvent::detect forces autodetection.
435 - implement signal watchers (experimental)
436 (Tk does not support async signals (<= 804.027 at least),
437 so they might get delayed indefinitely on Tk).
438 - implement child watchers (experimental).
439 - moved default condvar implementation into base module, simplifying
440 most implementation modules.
441
442 2.1 Fri Nov 24 15:50:48 CET 2006
443 - better docs.
444 - simple testsuite.
445 - added AnyEvent->one_event method for special purposes.
446
447 2.0 Wed Nov 1 02:21:30 CET 2006
448 - INCOMPATIBLE CHANGE: poll can now either be "r" or "w" but not both.
449 - INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
450 - EXPERIMENTAL:
451 new pure-perl model added, AnyEvent now always finds a suitable
452 event model.
453 - improved documentation.
454 - reduced cpu overhead.
455
456 1.02 Fri Jan 13 14:15:40 CET 2006
457 - add COPYING to clarify license.
458
459 1.01 Sun Jan 8 05:48:09 CET 2006
460 - correctly cancel Event timers, avoid memory leaks.
461
462 1.0 Sun Jan 8 05:40:58 CET 2006
463 - allow third-party interfaces to be added at runtime.

465
466 0.9 Fri Dec 30 02:25:41 CET 2005
467 - fixed errors in the documentation.
468 - going back to using $VERSION as "load check",
469 as suggested by Jörn Reder. Let's see why I stopped using
470 this method.
471 - add 'hup' to the list of events to receive for glib
472 and generate 'rw' events for it, as some versions of
473 glib seem to require this, while this breaks other
474 (older) versions of glib.
475 - implemented PERL_ANYEVENT_VERBOSE env variable.
476
477 0.3 Sun Dec 4 10:43:33 CET 2005

479 - fixed documentation.
480 - clarified some corner cases.
481 - vastly improved documentation with a long example.
482
483 0.2 Thu Dec 1 22:18:49 CET 2005
484 - check whether a valid method was called, to avoid endless loops.
485 - move condvars into their own class (cleaner, safer).
486 - don't die when some modules are not available.
487 - Tk is too broken to allow for words. Will work once Tk works.
488

490 - spiced up and cleaned up for release.
