1Revision history for Perl extension AnyEvent. 1Revision history for Perl extension AnyEvent.
2 2
3 - improve perl 5.6 compatibility of the core event loop.
4
54.83 Fri Jul 17 16:56:26 CEST 2009
6 - implement AnyEvent::Socket::getprotobyname.
7 - AnyEvent::CondVar's will now detect recursive blocking
8 waits and will croak, as too many people fall into
9 this trap.
10 - AnyEvent::Handle will now call ->destroy on itself after
11 executing the on_error callback, instead of doing some
12 half-baked internal shutdown, for fatal errors.
13 - clarify on_eof behaviour w.r.t. the read queue and
14 on_read callbacks.
15 - ignore some possible spurious wake-ups in tcp_connect.
16
174.82 Sat Jul 11 00:34:55 CEST 2009
18 - POE and Event backends didn't accept some callable objects as
19 callbacks.
20 - use Config module instead of POSIX module to detect signal names
21 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
22 module doesn't even have all POSIX signals :/.
23 - use more workarounds around the many refcnt/corruption bugs in
24 Event::Lib.
25 - work around a race condition in perl's select, causing t/03_child.t
26 to rarely fail.
27
284.81 Thu Jul 9 10:30:30 CEST 2009
29 - AnyEvent::Handle didn't properly diagnose write errors
30 (it expected -1 from syswrite, how lame... :).
31 - support file descriptors in addition to file handles
32 in AnyEvent->io.
33 - new env variables: PERL_ANYEVENT_RESOLV_CONF,
34 PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
35 and PERL_ANYEVENT_CA_PATH.
36 - provide a sensible synopsis section for AnyEvent::TLS.
37 - add a "supported backends" section to the manpage.
38 - added simple io watcher test to testsuite, using a
39 portable_socketpair.
40 - tried to improve the stability of the Event::Lib backend,
41 YMMV.
42
434.8 Mon Jul 6 23:45:16 CEST 2009
44 - AnyEvent::DNS did not properly follow CNAME records with
45 uppercase targets.
46 - AnyEvent::DNS would errornously return AAAA records
47 with v4 mapped addresses (a faulty record) as ipv4 addresses,
48 causing AnyEvent::Socket to throw an exception.
49 - added new module AnyEvent::TLS for easier SSL/TLS context
50 creation, with many options including hostname verification,
51 secure default configuration, lots of documentation and,
52 predefined diffie-hellman keys for perfect forward security
53 and much more. get it while it's still fresh!
54 - use AnyEvent::TLS in AnyEvent::Handle for context management.
55 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
56 so AnyEvent::Socket users have smaller memory footprint
57 in the common case.
58 - add AnyEvent::Handle->push_shutdown method.
59 - add an additional error message parameter to AnyEvent::Handle's
60 on_error callback (for TLS, $! is still available).
61 - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
62 - make AnyEvent::Handle more robust against early conenction
63 failures (during new), and return C<undef> in that case
64 from the constructor.
65 - AnyEvent::Handle will now try to load only JSON::XS first,
66 then fall back to JSON.
67 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
68 and because it was documented that way.
69
704.451 Fri Jul 3 00:28:58 CEST 2009
71 - do not clear rbuf when shutting down an AnyEvent::Handle
72 object - doing so breaks AnyEvent::HTTP.
73
744.45 Mon Jun 29 22:59:26 CEST 2009
75 - a write error could cause AnyEvent::Handle to create
76 an I/O watcher with an undefined $fh.
77 - special-case mapped ipv4 addresses in both
78 AnyEvent::Socket::format_address and parse_address,
79 to treat them just like ipv4 addresses.
80 - updated and overhauled the AnyEvent::Intro doc.
81 - implement AnyEvent::Socket::format_ipv4/ipv6.
82 - slightly speed up portable_pipe/socketpair.
83 - expand condvar begin/end documentation.
84
854.42 Fri Jun 26 08:32:18 CEST 2009
86 - preliminary and neccesarily incomplete support for IO::Async.
87 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
88 case it was set to IGNORE, to ensure we can catch child statuses
89 even when the calling env acts stupidly.
90 - updated benchmarks with IO::Async, which performs very well.
91
924.412 Wed Jun 24 01:35:57 CEST 2009
93 - support an "untaint" attribute for AnyEvent::DNS
94 and set it on the default resolver.
95 - implement and document AnyEvent::Impl::Perl::loop.
96 - remove all anyevent-env variables from %ENV
97 when running in tainted mode.
98 - mention and extend the IO::Lambda benchmark.
99
1004.411 Sun Jun 7 18:48:02 CEST 2009
101 - do not try to use F_SETFD on windows.
102
1034.41 Thu May 14 06:40:11 CEST 2009
104 - work around issues in older perls (5.8.0?) when
105 a signal handler is deleted from the %SIG hash.
106 - use POSIX::_exit in child test, to avoid running
107 destructors.
108 - speed up CHLD handling by relying on SIGCHLD being
109 synchronously delivered, even when we roll our own
110 implementation.
111 - AnyEvent::DNS: add the "dname" resource record name
112 for cosmetic reasons.
113
1144.4 Sun Apr 26 20:12:33 CEST 2009
115 - implemented idle watchers, where applicable.
116 - AnyEvent->time died when Event backend was in use.
117 - fix a memleak in the Tk backend.
118 - sped up Tk timer handling.
119 - clip negative "after" values to 0 in AnyEvent::Impl::Event
120 to avoid spamming out warning messages.
121 - fix Qt timers without interval.
122 - avoid Qt zero-timeout special case, in old libqt's.
123
1244.352 Mon Apr 20 16:31:11 CEST 2009
125 - fix AnyEvent::Strict error messages for child watchers.
126 - fix/update Makefile.PL "recommends" versions.
127 - add AnyEvent->now_update.
128
1294.351 Sat Apr 11 07:56:14 CEST 2009
130 - actually make the signal pipe work under win32.
131 - localise $! in signal handler to avoid changing $!, although
132 perl itself does not seem to save/restore errno either.
133 - set the cloexec flag on the signal pipe (normally set by perl too).
134
1354.35 Fri Mar 27 11:48:20 CET 2009
136 - event models relying on AnyEvent's signal watcher emulation did
137 invoke the callback asynchronously, contradicting documentation
138 and causing signals to get lost (this includes AnyEvent's own
139 event loop). AnyEvent now uses the standard pipe trick to make
140 callback execution synchronous to the event loop.
141 - AnyEvent::Handle didn't free TLS context data on DESTROY
142 (patch by Pavel Shaydo).
143 - work around the ever-incompatibly-changing API of MakeMaker.
144 - document that changing global variables without restoring them
145 is a bad idea in Perl (noted by Adam Rosenstein).
146 - AnyEvent::Strict now barfs if ->io is passed a file.
147
1484.34 Thu Feb 12 18:32:45 CET 2009
149 - separately buffer TLS read data, as otherwise the read queue could
150 deadlock as receiving data is not expected while draining the
151 read queue (which cna only happen with TLS).
152 - raise EBADMSG error on JSON decoding errors.
153 - fix some minor manpage bugs (reported by Maximilian Gaß).
154 - speed up select bitmask parsing quite a bit in the pure perl
155 backend.
156 - use CORE::select instead of just select in AnyEvent::Impl::Perl.
157
1584.331 Tue Jan 6 21:07:25 CET 2009
159 - socketpair fails on many vista machines because vista has
160 completely broken accept/getpeername and getsockname functions,
161 so we provide our own socketpair emulation that kind of works
162 (AnyEvent::Util::portable_pipe).
163 - new function: AnyEvent::Util::portable_socketpair.
164 - take advantage of the Guard module if it exists.
165
1664.33 Fri Nov 21 02:35:40 CET 2008
167 - AnyEvent::Strict did errornously flag a fileno of 0 as
168 illegal.
169 - reduce memory usage and slightly speed up the pure perl backend
170 by only storing the file descriptor, not the file handle.
171 - add missing autocork method to AnyEvent::Handle (reported
172 by Adam Rosenstein).
173 - AnyEvent::DNS->resolve errornously documented an $rcode result
174 argument, but there isn't (spotted by Henrik Krohns).
175 - the naked truth about Tk - it's basically unmaintained.
176
1774.32 Mon Nov 3 22:46:32 CET 2008
178 - fix AnyEvent::Socket::resolve_sockaddr to properly support
179 unix sockets again and choose a proper default for
180 the socket type.
181 - fix call to resolve_sockaddr in tcp_connect.
182
1834.31 Thu Oct 30 04:41:48 CET 2008
184 - implemented AnyEvent::Handle->destroy method.
185 - hint about unexpected effects in TLS mode.
186 - speed up AnyEvent::Impl::Perl by using more arrays
187 instead of hashes without the slightest loss of readability :)
188 - work around a perl argument refcounting bug.
189 - with some perl patches applied, AnyEvent now seems leak-free.
190
1914.3 Fri Oct 3 09:18:43 CEST 2008
192 - AnyEvent will now install a no-op signal handler for SIGPIPE,
193 unless one has been installed already.
194 - warn about not loaidng AnyEvent::Impl::POE early enough
195 (patch by Adam Rosenstein).
196 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
197 - fix a bug in where in SSL connect mode, the
198 client would first wait for some data by the server and
199 otherwise hang. (reported and analyzed in an absolutely
200 exemplary manner by Adam Rosenstein).
201 - fix a bug in where SSL EOF would not be treated
202 as stream EOF, putting the connection into a hung state.
203 (reported and analyzed in an absolutely exemplary manner by Adam
204 Rosenstein).
205 - fix a potential segfault when the TLS context
206 would go missing in a read callback (e.g. due to stoptls) -
207 Net::SSLeay of course makes no type checking whatsoever.
208 - AnyEvent::Handle will not stop the read watcher in TLS mode.
209 - AnyEvent::Handle->stoptls will send a TLS close notify
210 instead of simply destroying the stream now.
211 - fix a bug where large blocks of data written in TLS mode
212 would not be sent unless triggered by receives.
213 - on_drain will now take the tls write buffer into account.
214 - SSL operations have been streamlined a bit and should be faster
215 now, more to come, though.
216 - added a FAQ section, will document nontrivial issues in there.
217
2184.234 Mon Sep 29 04:08:13 CEST 2008
219 - fix child watcher documentation: only child exits will be reported,
220 no trace events.
221 - mention SIGPIPE in AnyEvent::Handle.
222 - perl backend will now use POSIX::times as monotonic clock
223 when available and the monotonic clock option is not.
224 - run even without Time::HiRes in some cases now, but do not
225 provide sub-second accuracy (all *supported* perl versions have
226 Time::HiRes).
227
2284.233 Fri Aug 22 01:48:05 CEST 2008
229 - fix a bug in the testsuite, causing a hang.
230 - clarified lots of AnyEvent::Handle constructor arguments.
231
2324.232 Thu Aug 21 20:44:25 CEST 2008
233 - fix a bug in AnyEvent::Handle that could cause two fatal error
234 callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
235 (testcase by Leon Brocard).
236 - clarified on_eof/on_error documentation a bit.
237
2384.231 Tue Jul 29 13:12:15 CEST 2008
239 - remove some debugging code left in AnyEvent::Util::fork_call
240 (and no, it's impossible to implement with the broken windows
241 perls without resource leaks or worse).
242
2434.23 Tue Jul 29 12:19:59 CEST 2008
244 - document the first parameter passed to condvar callbacks to be
245 the callback.
246 - add AnyEvent::Socket::{ntoa,aton} aliases.
247 - optimize the AE::Handle->push_read (line) for the default
248 eol marker.
249 - optimize push_read (packstring|storable) for small packets.
250 - invoke on_error callback when no on_eof callback is set.
251 - fix a bug in push_read (storable) of unknown impact.
252
2534.22 Sun Jul 20 16:34:13 CEST 2008
254 - new function AnyEvent::Socket::parse_hostport.
255 - as the bulkheads at microsoft can't even get getprotobyname reliably
256 working on their shitty fucking broken os we need to hardcode
257 some common protocol numbers in AnyEvent::Socket. How can
258 people even bother with such a pile of shit as windows.
259
2604.21 Thu Jul 17 14:40:05 CEST 2008
261 - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
262 which is incompatible to previous invocation syntax.
263 - work around more windows perl bugs in fork_call. I cannot imagine
264 why anybody would bother implementing fork in such an obviously
265 unusable way.
266 - avoid calling $do_retry if the request has already finished in
267 AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
268 K. Sharifulin).
269
2704.2 Sat Jul 12 22:42:11 CEST 2008
271 - support an "interval" argument for repeating timers.
272 - fix a bug in the pure perl event loop that caused timers to
273 be delayed under some circumstances.
274 - implement optional argument checking via PERL_ANYEVENT_STRICT.
275 - not importing anything from Event causes it to malfunction
276 and not use Time::HiRes, work around this bug.
277 - more bug workarounds against the endlessly broken Tk module,
278 seems to work now on 32 bit machines, but less so on 64 bit.
279 - minor optimisations applied to most backends.
280
2814.161 Fri Jul 4 14:24:48 CEST 2008
282 - fixed the t/handle/02_write.t, it read after write, with the
283 assumption that all data could be written before read
284 (reported by Jim Razmus).
285
2864.160 Thu Jul 3 04:02:21 CEST 2008
287 - re-registering signal watchers after unregistering one did
288 not work if a backend falls back on AnyEvent's default
289 implementation (also affected child watchers).
290 - new AnyEvent::Handle options: autocork and no_delay.
291
2924.152 Sun Jun 22 14:15:44 CEST 2008
293 - allow for 32-bit perls that implement shifts differently
294 on different architectures in parse_ipv4 (reported and
295 analysed by Keiichi DAIBA).
296
2974.151 Fri Jun 6 17:34:24 CEST 2008
298 - make sure specifying _only_ on_read and never pushing reads
299 works.
300
3014.15 Fri Jun 6 13:00:46 CEST 2008
302 - the pure perl backend would keep some watchers alive when more than
303 one watcher was registered for the same fd.
304 - new "packstring" and "storable" read and write types
305 for AnyEvent::Handle.
306 - allow on_eof handler to be called after on_error with EPIPE returns.
307 - do not immediately call on_read callback in handle constructor.
308
3094.14 Thu Jun 5 20:29:31 CEST 2008
310 - Fixed a bug in DNS SRV priority sorting.
311 - AnyEvent::Util::guard now reports runtime errors while
312 executing the guard block as warnings.
313 - handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.
314
3154.13 Thu Jun 5 00:47:59 CEST 2008
316 - AnyEvent::DNS only followed cname chains with length 2,
317 contrary to documentation. bumped it up to 10, thanks to
318 microsoft, the current broken-dns-config-king.
319 - AnyEvent::DNS didn't check for socket return status
320 but instead relied on perl not creating filehandles in that
321 case - too bad it gives you a bogus file handle (reported
322 and analysed by Vladimir Timofeev).
323 - fix queue management logic in AnyEvent::Handle:
324 when on_read was registered, the queue was empty
325 and no progress could be made AnyEvent::Handle would
326 enter an endless loop.
327 - correctly start reading again when the handle became
328 busy again after idling.
329 - correctly treat tls shut-downs as EOF condition
330 (for the time being, would be nice to have a callback for that).
331 - correctly call eof callback under all conditions
332 (hopefully).
333 - the timeout callback did not expect that $self can go
334 away any time.
335
3364.12 Tue Jun 3 10:58:04 CEST 2008
337 - include AnyEvent::Intro, a tutorial for anyevent,
338 anyevent::socket and anyevent::handle.
339 - allow more options in on_error.
340
3414.11 Fri May 30 23:42:25 CEST 2008
342 - INCOMPATIBLE CHANGE: replace ptr by real PTR lookup, provide
343 reverse_lookup and reverse_verify to replace it, support
344 v4mapped and v4compat addresses.
345 - provide more documentation for the resolver class.
346 - really replace longest run of :0: by :: in format_address,
347 also properly convert :: and ::1 again.
348 - support NAPTR record name and decode it.
349 - implement random weight sampling for SRV records, as per
350 rfc 2782.
351 - correctly abort on srv-record targets of ".".
352 - added AnyEvent::DNS::wait_for_slot.
353 - in the unlikely event of a virtual circuit connection
354 being invalidated by a delayed udp reply, AnyEvent::DNS
355 could die. this has been fixed.
356 - plug a probable memleak in the DNS vc code.
357 - use configured timeout also for VC request phase.
358 - implement timeout and max_outstanding methods
359 for resolver class.
360 - update version numbers in all modules.
361
3624.1 Thu May 29 05:45:40 CEST 2008
363 - INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address
364 which mirrors their purpose better (old names still available
365 for a while). Also moved AnyEvent::DNS::addr to
366 AnyEvent::Socket::resolve_sockaddr.
367 - implement AnyEvent->time and AnyEvent->now.
368 - fix IPv6 support in pack_sockaddr.
369 - officially un-experimentalise all newly introduced code.
370 - support unix domain sockets everywhere by specifying
371 a host of "unix/" and the pathname as service.
372 - implement an activity timeout in AnyEvent::Handle.
373 - added a regex read type to AnyEvent::Handle.
374 - added a json read/write type to AnyEvent::Handle.
375 - always croak in on_error in AnyEvent::Handle.
376 - document how to subclass AnyEvent::Handle.
377 - implement AnyEvent::Util::fork_call.
378 - add support for IPv6 nameservers and nameserver statements.
379 - work around _yet_ _another_ windows perl bug in where empty
380 select masks cause errors in the pure perl backend (this
381 workaround cannot be implemented for the other event loops,
382 but EV also works around this).
383 - supply AnyEvent::Socket::address_type and make good use of it.
384 - clarify and fix the Handle documentation w.r.t $self vs. $handle
385 vs. callback arguments.
386 - add some recommends to the META.yml.
387
3884.05 Mon May 26 19:44:06 CEST 2008
389 - some platforms ignore the rfc and prepend an extra sa_len member to
390 the sockaddr structure, cater for those. also use sockaddr_family,
391 didn't know it was there, but comes in handy for the workaround.
392 - undo the import WIN32 hack.
393
3944.04 Mon May 26 08:03:31 CEST 2008
395 - try to work around yet another windows bug: failed connects are reported
396 as if it were out-of-band data. windows users: you suck. Only
397 EV, Glib, Event and the pure perl backend can handle this condition.
398 - optimize write algorithm in AnyEvent::Handle.
3 - properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly. 399 - properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
400 - tcp_connect now properly iterates through all targets.
4 - check wether IPv6 sockets can actually be created, otherwise, disable ipv6 401 - check wether IPv6 sockets can actually be created, otherwise, disable ipv6
5 support entirely. also hardcode some AF_INEt6 constants for the 402 support entirely. also hardcode some AF_INET6 constants for the
6 sake of perl 5.8. 403 sake of perl 5.8.
7 - vastly improved nameserver/suffix detection algorithm for windows 404 - vastly improved nameserver/suffix detection algorithm for windows
