1Revision history for Perl extension AnyEvent. 1Revision history for Perl extension AnyEvent.
2
3 - fixed wrong documentation in AE::Socket.
4
55.01 Mon Aug 10 03:16:32 CEST 2009
6 - last release broke EV child watchers :/.
7
85.0 Sun Aug 9 17:32:09 CEST 2009
9 - officially introduce and document the AE API.
10 - lowering the timeout at runtime did not have immediate effect
11 in AnyEvent::Handle.
12 - AE::Handle now has separate and independent read and write timeout
13 settings.
14 - probe for Guard module when AnyEvent::Util is loaded, not at
15 runtime (Event doesn't like eval "use" from callbacks, and it avoids
16 exporting the probe function).
17 - Impl::IOAsync's io watchers did not use the filehandle emulation
18 code to work around it's watcher limits.
19 - work around IO::Async's problems with overloaded objects.
20 - try to disable wearnings inside IO::Async, it's just too buggy.
21 - do no longer use Event by default, only EV or Perl, Event is too buggy.
22 - hackishly provide fast AE:: interface when EV or Perl is the backend.
23 - inherit VERSION from AnyEvent::VERSION in most modules.
24
254.91 Thu Aug 6 15:42:45 CEST 2009
26 - AE::Handle::starttls could get out of sync when the read buffer
27 already contains some TLS handshake.
28 - AE::Handle did not properly free the TLS session, causing bigger
29 memory leaks in Net::SSLeay than expected (reported by toaster).
30 - AE::Socket::tcp_connect will now artificially delay invoking
31 the callback to avoid returning after invoking the callback.
32 - convert many internal watcher uses to AE API.
33
344.9 Sat Aug 1 11:07:01 CEST 2009
35 - Glib silently fails when registering a timeout with
36 a negative value, so avoid that.
37 - call condvar callback immediately when it is set
38 after the condition is already signalled.
39 - check rbuf_max condition only after trying to consume
40 data.
41 - normalise signal numbers to names when using the ae's
42 signal handling, but do not document this (yet).
43 - pure perl signal emulation did not properly set nonblocking
44 mode on the signal pipe on win32 (this is unlikely to have caused
45 any issues).
46 - new module: AnyEvent::Debug.
47 - AnyEvent::Strict now checks that a signal was specified
48 by name (not name or number).
49 - reduce memory footprint in typical cases by ~50kb by
50 only compiling signal code when necessary.
51 - add AnyEvent::Handle->rbuf_max.
52 - grab the AE namespace for future new API, implement stubs for
53 said future/alternative API.
54 - new function: AnyEvent::Socket::format_hostport.
55
564.881 Tue Jul 28 12:51:53 CEST 2009
57 - work around a bug in local in pre-5.10 perls, causing
58 AnyEvent::Handle to recurse when it should not
59 (analyzed by elmex).
60
614.88 Tue Jul 28 04:04:37 CEST 2009
62 - re-bless the handle into a dummy package after calling
63 AnyEvent::Handle::destroy, so the user does not need to check
64 for errors after every push_write etc.
65 - do not attempt to run t/02_signals.t on obviously broken
66 platforms.
67
684.87 Sun Jul 26 02:06:16 CEST 2009
69 - do not attempt to linger when there is no longer a valid fh.
70 - enforce tls mode to be either accept or connect, do not simply
71 segfault in Net::SSLeay.
72 - AnyEvent::Handle can now call tcp_connect itself (new parameters
73 connect, on_prepare, on_connect and on_connect_error). Updated
74 tutorial accordingly.
75 - add AnyEvent::Impl::Irssi backend.
76
774.86 Mon Jul 20 23:52:29 CEST 2009
78 - since the verbose warning is not enough, explicitly document
79 that versions before 1.33 of Net::SSLeay are not secure.
80 - work around signal handling races in Event and (...) Event::Lib.
81 - try to align signal-race timer to full-second boundaries.
82 - work around Tk not liking negative timeouts.
83 - don't complain of different grades of environmental unfriendlyness
84 in IO::Async.
85
864.85 Sat Jul 18 06:16:14 CEST 2009
87 - nail the signal race problem in perl once and for all
88 (see $AnyEvent::MAX_SIGNAL_LATENCY).
89 - take advantage of Async::Interrupt if it is available.
90 - load Time::HiRes and Guard modules on demand only.
91 - add optional/recommended modules section to AnyEvent
92 documentation.
93 - reduce memory usage considerably (and reduce startup penalty)
94 by not using "strict", "warnings" and "overload" modules.
95 - work around buggy windows/openbsd perls and provide EBADMSG
96 and EPROTO ourselves when missing.
97 - improve perl 5.6 compatibility of the core event loop.
98 - made Net::SSLeay version 1.33 a soft requirement.
99
1004.83 Fri Jul 17 16:56:26 CEST 2009
101 - implement AnyEvent::Socket::getprotobyname.
102 - AnyEvent::CondVar's will now detect recursive blocking
103 waits and will croak, as too many people fall into
104 this trap.
105 - AnyEvent::Handle will now call ->destroy on itself after
106 executing the on_error callback, instead of doing some
107 half-baked internal shutdown, for fatal errors.
108 - clarify on_eof behaviour w.r.t. the read queue and
109 on_read callbacks.
110 - ignore some possible spurious wake-ups in tcp_connect.
111
1124.82 Sat Jul 11 00:34:55 CEST 2009
113 - POE and Event backends didn't accept some callable objects as
114 callbacks.
115 - use Config module instead of POSIX module to detect signal names
116 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
117 module doesn't even have all POSIX signals :/.
118 - use more workarounds around the many refcnt/corruption bugs in
119 Event::Lib.
120 - work around a race condition in perl's select, causing t/03_child.t
121 to rarely fail.
122
1234.81 Thu Jul 9 10:30:30 CEST 2009
124 - AnyEvent::Handle didn't properly diagnose write errors
125 (it expected -1 from syswrite, how lame... :).
126 - support file descriptors in addition to file handles
127 in AnyEvent->io.
128 - new env variables: PERL_ANYEVENT_RESOLV_CONF,
129 PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
130 and PERL_ANYEVENT_CA_PATH.
131 - provide a sensible synopsis section for AnyEvent::TLS.
132 - add a "supported backends" section to the manpage.
133 - added simple io watcher test to testsuite, using a
134 portable_socketpair.
135 - tried to improve the stability of the Event::Lib backend,
136 YMMV.
137
1384.8 Mon Jul 6 23:45:16 CEST 2009
139 - AnyEvent::DNS did not properly follow CNAME records with
140 uppercase targets.
141 - AnyEvent::DNS would errornously return AAAA records
142 with v4 mapped addresses (a faulty record) as ipv4 addresses,
143 causing AnyEvent::Socket to throw an exception.
144 - added new module AnyEvent::TLS for easier SSL/TLS context
145 creation, with many options including hostname verification,
146 secure default configuration, lots of documentation and,
147 predefined diffie-hellman keys for perfect forward security
148 and much more. get it while it's still fresh!
149 - use AnyEvent::TLS in AnyEvent::Handle for context management.
150 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
151 so AnyEvent::Socket users have smaller memory footprint
152 in the common case.
153 - add AnyEvent::Handle->push_shutdown method.
154 - add an additional error message parameter to AnyEvent::Handle's
155 on_error callback (for TLS, $! is still available).
156 - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
157 - make AnyEvent::Handle more robust against early conenction
158 failures (during new), and return C<undef> in that case
159 from the constructor.
160 - AnyEvent::Handle will now try to load only JSON::XS first,
161 then fall back to JSON.
162 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
163 and because it was documented that way.
164
1654.451 Fri Jul 3 00:28:58 CEST 2009
166 - do not clear rbuf when shutting down an AnyEvent::Handle
167 object - doing so breaks AnyEvent::HTTP.
168
1694.45 Mon Jun 29 22:59:26 CEST 2009
170 - a write error could cause AnyEvent::Handle to create
171 an I/O watcher with an undefined $fh.
172 - special-case mapped ipv4 addresses in both
173 AnyEvent::Socket::format_address and parse_address,
174 to treat them just like ipv4 addresses.
175 - updated and overhauled the AnyEvent::Intro doc.
176 - implement AnyEvent::Socket::format_ipv4/ipv6.
177 - slightly speed up portable_pipe/socketpair.
178 - expand condvar begin/end documentation.
179
1804.42 Fri Jun 26 08:32:18 CEST 2009
181 - preliminary and neccesarily incomplete support for IO::Async.
182 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
183 case it was set to IGNORE, to ensure we can catch child statuses
184 even when the calling env acts stupidly.
185 - updated benchmarks with IO::Async, which performs very well.
186
1874.412 Wed Jun 24 01:35:57 CEST 2009
188 - support an "untaint" attribute for AnyEvent::DNS
189 and set it on the default resolver.
190 - implement and document AnyEvent::Impl::Perl::loop.
191 - remove all anyevent-env variables from %ENV
192 when running in tainted mode.
193 - mention and extend the IO::Lambda benchmark.
194
1954.411 Sun Jun 7 18:48:02 CEST 2009
196 - do not try to use F_SETFD on windows.
197
1984.41 Thu May 14 06:40:11 CEST 2009
199 - work around issues in older perls (5.8.0?) when
200 a signal handler is deleted from the %SIG hash.
201 - use POSIX::_exit in child test, to avoid running
202 destructors.
203 - speed up CHLD handling by relying on SIGCHLD being
204 synchronously delivered, even when we roll our own
205 implementation.
206 - AnyEvent::DNS: add the "dname" resource record name
207 for cosmetic reasons.
208
2094.4 Sun Apr 26 20:12:33 CEST 2009
210 - implemented idle watchers, where applicable.
211 - AnyEvent->time died when Event backend was in use.
212 - fix a memleak in the Tk backend.
213 - sped up Tk timer handling.
214 - clip negative "after" values to 0 in AnyEvent::Impl::Event
215 to avoid spamming out warning messages.
216 - fix Qt timers without interval.
217 - avoid Qt zero-timeout special case, in old libqt's.
218
2194.352 Mon Apr 20 16:31:11 CEST 2009
220 - fix AnyEvent::Strict error messages for child watchers.
221 - fix/update Makefile.PL "recommends" versions.
222 - add AnyEvent->now_update.
223
2244.351 Sat Apr 11 07:56:14 CEST 2009
225 - actually make the signal pipe work under win32.
226 - localise $! in signal handler to avoid changing $!, although
227 perl itself does not seem to save/restore errno either.
228 - set the cloexec flag on the signal pipe (normally set by perl too).
229
2304.35 Fri Mar 27 11:48:20 CET 2009
231 - event models relying on AnyEvent's signal watcher emulation did
232 invoke the callback asynchronously, contradicting documentation
233 and causing signals to get lost (this includes AnyEvent's own
234 event loop). AnyEvent now uses the standard pipe trick to make
235 callback execution synchronous to the event loop.
236 - AnyEvent::Handle didn't free TLS context data on DESTROY
237 (patch by Pavel Shaydo).
238 - work around the ever-incompatibly-changing API of MakeMaker.
239 - document that changing global variables without restoring them
240 is a bad idea in Perl (noted by Adam Rosenstein).
241 - AnyEvent::Strict now barfs if ->io is passed a file.
242
2434.34 Thu Feb 12 18:32:45 CET 2009
244 - separately buffer TLS read data, as otherwise the read queue could
245 deadlock as receiving data is not expected while draining the
246 read queue (which cna only happen with TLS).
247 - raise EBADMSG error on JSON decoding errors.
248 - fix some minor manpage bugs (reported by Maximilian Gaß).
249 - speed up select bitmask parsing quite a bit in the pure perl
250 backend.
251 - use CORE::select instead of just select in AnyEvent::Impl::Perl.
252
2534.331 Tue Jan 6 21:07:25 CET 2009
254 - socketpair fails on many vista machines because vista has
255 completely broken accept/getpeername and getsockname functions,
256 so we provide our own socketpair emulation that kind of works
257 (AnyEvent::Util::portable_pipe).
258 - new function: AnyEvent::Util::portable_socketpair.
259 - take advantage of the Guard module if it exists.
260
2614.33 Fri Nov 21 02:35:40 CET 2008
262 - AnyEvent::Strict did errornously flag a fileno of 0 as
263 illegal.
264 - reduce memory usage and slightly speed up the pure perl backend
265 by only storing the file descriptor, not the file handle.
266 - add missing autocork method to AnyEvent::Handle (reported
267 by Adam Rosenstein).
268 - AnyEvent::DNS->resolve errornously documented an $rcode result
269 argument, but there isn't (spotted by Henrik Krohns).
270 - the naked truth about Tk - it's basically unmaintained.
271
2724.32 Mon Nov 3 22:46:32 CET 2008
273 - fix AnyEvent::Socket::resolve_sockaddr to properly support
274 unix sockets again and choose a proper default for
275 the socket type.
276 - fix call to resolve_sockaddr in tcp_connect.
277
2784.31 Thu Oct 30 04:41:48 CET 2008
279 - implemented AnyEvent::Handle->destroy method.
280 - hint about unexpected effects in TLS mode.
281 - speed up AnyEvent::Impl::Perl by using more arrays
282 instead of hashes without the slightest loss of readability :)
283 - work around a perl argument refcounting bug.
284 - with some perl patches applied, AnyEvent now seems leak-free.
285
2864.3 Fri Oct 3 09:18:43 CEST 2008
287 - AnyEvent will now install a no-op signal handler for SIGPIPE,
288 unless one has been installed already.
289 - warn about not loaidng AnyEvent::Impl::POE early enough
290 (patch by Adam Rosenstein).
291 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
292 - fix a bug in where in SSL connect mode, the
293 client would first wait for some data by the server and
294 otherwise hang. (reported and analyzed in an absolutely
295 exemplary manner by Adam Rosenstein).
296 - fix a bug in where SSL EOF would not be treated
297 as stream EOF, putting the connection into a hung state.
298 (reported and analyzed in an absolutely exemplary manner by Adam
299 Rosenstein).
300 - fix a potential segfault when the TLS context
301 would go missing in a read callback (e.g. due to stoptls) -
302 Net::SSLeay of course makes no type checking whatsoever.
303 - AnyEvent::Handle will not stop the read watcher in TLS mode.
304 - AnyEvent::Handle->stoptls will send a TLS close notify
305 instead of simply destroying the stream now.
306 - fix a bug where large blocks of data written in TLS mode
307 would not be sent unless triggered by receives.
308 - on_drain will now take the tls write buffer into account.
309 - SSL operations have been streamlined a bit and should be faster
310 now, more to come, though.
311 - added a FAQ section, will document nontrivial issues in there.
312
3134.234 Mon Sep 29 04:08:13 CEST 2008
314 - fix child watcher documentation: only child exits will be reported,
315 no trace events.
316 - mention SIGPIPE in AnyEvent::Handle.
317 - perl backend will now use POSIX::times as monotonic clock
318 when available and the monotonic clock option is not.
319 - run even without Time::HiRes in some cases now, but do not
320 provide sub-second accuracy (all *supported* perl versions have
321 Time::HiRes).
322
3234.233 Fri Aug 22 01:48:05 CEST 2008
324 - fix a bug in the testsuite, causing a hang.
325 - clarified lots of AnyEvent::Handle constructor arguments.
326
3274.232 Thu Aug 21 20:44:25 CEST 2008
328 - fix a bug in AnyEvent::Handle that could cause two fatal error
329 callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
330 (testcase by Leon Brocard).
331 - clarified on_eof/on_error documentation a bit.
332
3334.231 Tue Jul 29 13:12:15 CEST 2008
334 - remove some debugging code left in AnyEvent::Util::fork_call
335 (and no, it's impossible to implement with the broken windows
336 perls without resource leaks or worse).
337
3384.23 Tue Jul 29 12:19:59 CEST 2008
339 - document the first parameter passed to condvar callbacks to be
340 the callback.
341 - add AnyEvent::Socket::{ntoa,aton} aliases.
342 - optimize the AE::Handle->push_read (line) for the default
343 eol marker.
344 - optimize push_read (packstring|storable) for small packets.
345 - invoke on_error callback when no on_eof callback is set.
346 - fix a bug in push_read (storable) of unknown impact.
347
3484.22 Sun Jul 20 16:34:13 CEST 2008
349 - new function AnyEvent::Socket::parse_hostport.
350 - as the bulkheads at microsoft can't even get getprotobyname reliably
351 working on their shitty fucking broken os we need to hardcode
352 some common protocol numbers in AnyEvent::Socket. How can
353 people even bother with such a pile of shit as windows.
354
3554.21 Thu Jul 17 14:40:05 CEST 2008
356 - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
357 which is incompatible to previous invocation syntax.
358 - work around more windows perl bugs in fork_call. I cannot imagine
359 why anybody would bother implementing fork in such an obviously
360 unusable way.
361 - avoid calling $do_retry if the request has already finished in
362 AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
363 K. Sharifulin).
364
3654.2 Sat Jul 12 22:42:11 CEST 2008
366 - support an "interval" argument for repeating timers.
367 - fix a bug in the pure perl event loop that caused timers to
368 be delayed under some circumstances.
369 - implement optional argument checking via PERL_ANYEVENT_STRICT.
370 - not importing anything from Event causes it to malfunction
371 and not use Time::HiRes, work around this bug.
372 - more bug workarounds against the endlessly broken Tk module,
373 seems to work now on 32 bit machines, but less so on 64 bit.
374 - minor optimisations applied to most backends.
375
3764.161 Fri Jul 4 14:24:48 CEST 2008
377 - fixed the t/handle/02_write.t, it read after write, with the
378 assumption that all data could be written before read
379 (reported by Jim Razmus).
380
3814.160 Thu Jul 3 04:02:21 CEST 2008
382 - re-registering signal watchers after unregistering one did
383 not work if a backend falls back on AnyEvent's default
384 implementation (also affected child watchers).
385 - new AnyEvent::Handle options: autocork and no_delay.
386
3874.152 Sun Jun 22 14:15:44 CEST 2008
388 - allow for 32-bit perls that implement shifts differently
389 on different architectures in parse_ipv4 (reported and
390 analysed by Keiichi DAIBA).
391
3924.151 Fri Jun 6 17:34:24 CEST 2008
393 - make sure specifying _only_ on_read and never pushing reads
394 works.
395
3964.15 Fri Jun 6 13:00:46 CEST 2008
397 - the pure perl backend would keep some watchers alive when more than
398 one watcher was registered for the same fd.
399 - new "packstring" and "storable" read and write types
400 for AnyEvent::Handle.
401 - allow on_eof handler to be called after on_error with EPIPE returns.
402 - do not immediately call on_read callback in handle constructor.
403
4044.14 Thu Jun 5 20:29:31 CEST 2008
405 - Fixed a bug in DNS SRV priority sorting.
406 - AnyEvent::Util::guard now reports runtime errors while
407 executing the guard block as warnings.
408 - handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.
409
4104.13 Thu Jun 5 00:47:59 CEST 2008
411 - AnyEvent::DNS only followed cname chains with length 2,
412 contrary to documentation. bumped it up to 10, thanks to
413 microsoft, the current broken-dns-config-king.
414 - AnyEvent::DNS didn't check for socket return status
415 but instead relied on perl not creating filehandles in that
416 case - too bad it gives you a bogus file handle (reported
417 and analysed by Vladimir Timofeev).
418 - fix queue management logic in AnyEvent::Handle:
419 when on_read was registered, the queue was empty
420 and no progress could be made AnyEvent::Handle would
421 enter an endless loop.
422 - correctly start reading again when the handle became
423 busy again after idling.
424 - correctly treat tls shut-downs as EOF condition
425 (for the time being, would be nice to have a callback for that).
426 - correctly call eof callback under all conditions
427 (hopefully).
428 - the timeout callback did not expect that $self can go
429 away any time.
430
4314.12 Tue Jun 3 10:58:04 CEST 2008
432 - include AnyEvent::Intro, a tutorial for anyevent,
433 anyevent::socket and anyevent::handle.
434 - allow more options in on_error.
435
4364.11 Fri May 30 23:42:25 CEST 2008
437 - INCOMPATIBLE CHANGE: replace ptr by real PTR lookup, provide
438 reverse_lookup and reverse_verify to replace it, support
439 v4mapped and v4compat addresses.
440 - provide more documentation for the resolver class.
441 - really replace longest run of :0: by :: in format_address,
442 also properly convert :: and ::1 again.
443 - support NAPTR record name and decode it.
444 - implement random weight sampling for SRV records, as per
445 rfc 2782.
446 - correctly abort on srv-record targets of ".".
447 - added AnyEvent::DNS::wait_for_slot.
448 - in the unlikely event of a virtual circuit connection
449 being invalidated by a delayed udp reply, AnyEvent::DNS
450 could die. this has been fixed.
451 - plug a probable memleak in the DNS vc code.
452 - use configured timeout also for VC request phase.
453 - implement timeout and max_outstanding methods
454 for resolver class.
455 - update version numbers in all modules.
2 456
34.1 Thu May 29 05:45:40 CEST 2008 4574.1 Thu May 29 05:45:40 CEST 2008
4 - INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address 458 - INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address
5 which mirrors their purpose better (old names still available 459 which mirrors their purpose better (old names still available
6 for a while). Also moved AnyEvent::DNS::addr to 460 for a while). Also moved AnyEvent::DNS::addr to
78 - support service names in tcp_connect and tcp_server. 532 - support service names in tcp_connect and tcp_server.
