2 2
3TODO: implement condvars... 3 - use Config module instead of POSIX module to detect signal names
4 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
5 module doesn't even have all POSIX signals :/.
6 - use more workarounds around the many refcnt/corruption bugs in
7 Event::Lib.
8 - work around a race condition in perl's select, causing t/03_child.t
9 to rarely fail.
10
114.81 Thu Jul 9 10:30:30 CEST 2009
12 - AnyEvent::Handle didn't properly diagnose write errors
13 (it expected -1 from syswrite, how lame... :).
14 - support file descriptors in addition to file handles
15 in AnyEvent->io.
16 - new env variables: PERL_ANYEVENT_RESOLV_CONF,
17 PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
18 and PERL_ANYEVENT_CA_PATH.
19 - provide a sensible synopsis section for AnyEvent::TLS.
20 - add a "supported backends" section to the manpage.
21 - added simple io watcher test to testsuite, using a
22 portable_socketpair.
23 - tried to improve the stability of the Event::Lib backend,
24 YMMV.
25
264.8 Mon Jul 6 23:45:16 CEST 2009
27 - AnyEvent::DNS did not properly follow CNAME records with
28 uppercase targets.
29 - AnyEvent::DNS would errornously return AAAA records
30 with v4 mapped addresses (a faulty record) as ipv4 addresses,
31 causing AnyEvent::Socket to throw an exception.
32 - added new module AnyEvent::TLS for easier SSL/TLS context
33 creation, with many options including hostname verification,
34 secure default configuration, lots of documentation and,
35 predefined diffie-hellman keys for perfect forward security
36 and much more. get it while it's still fresh!
37 - use AnyEvent::TLS in AnyEvent::Handle for context management.
38 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
39 so AnyEvent::Socket users have smaller memory footprint
40 in the common case.
41 - add AnyEvent::Handle->push_shutdown method.
42 - add an additional error message parameter to AnyEvent::Handle's
43 on_error callback (for TLS, $! is still available).
44 - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
45 - make AnyEvent::Handle more robust against early conenction
46 failures (during new), and return C<undef> in that case
47 from the constructor.
48 - AnyEvent::Handle will now try to load only JSON::XS first,
49 then fall back to JSON.
50 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
51 and because it was documented that way.
52
534.451 Fri Jul 3 00:28:58 CEST 2009
54 - do not clear rbuf when shutting down an AnyEvent::Handle
55 object - doing so breaks AnyEvent::HTTP.
56
574.45 Mon Jun 29 22:59:26 CEST 2009
58 - a write error could cause AnyEvent::Handle to create
59 an I/O watcher with an undefined $fh.
60 - special-case mapped ipv4 addresses in both
61 AnyEvent::Socket::format_address and parse_address,
62 to treat them just like ipv4 addresses.
63 - updated and overhauled the AnyEvent::Intro doc.
64 - implement AnyEvent::Socket::format_ipv4/ipv6.
65 - slightly speed up portable_pipe/socketpair.
66 - expand condvar begin/end documentation.
67
684.42 Fri Jun 26 08:32:18 CEST 2009
69 - preliminary and neccesarily incomplete support for IO::Async.
70 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
71 case it was set to IGNORE, to ensure we can catch child statuses
72 even when the calling env acts stupidly.
73 - updated benchmarks with IO::Async, which performs very well.
74
754.412 Wed Jun 24 01:35:57 CEST 2009
76 - support an "untaint" attribute for AnyEvent::DNS
77 and set it on the default resolver.
78 - implement and document AnyEvent::Impl::Perl::loop.
79 - remove all anyevent-env variables from %ENV
80 when running in tainted mode.
81 - mention and extend the IO::Lambda benchmark.
82
834.411 Sun Jun 7 18:48:02 CEST 2009
84 - do not try to use F_SETFD on windows.
85
864.41 Thu May 14 06:40:11 CEST 2009
87 - work around issues in older perls (5.8.0?) when
88 a signal handler is deleted from the %SIG hash.
89 - use POSIX::_exit in child test, to avoid running
90 destructors.
91 - speed up CHLD handling by relying on SIGCHLD being
92 synchronously delivered, even when we roll our own
93 implementation.
94 - AnyEvent::DNS: add the "dname" resource record name
95 for cosmetic reasons.
96
974.4 Sun Apr 26 20:12:33 CEST 2009
98 - implemented idle watchers, where applicable.
99 - AnyEvent->time died when Event backend was in use.
100 - fix a memleak in the Tk backend.
101 - sped up Tk timer handling.
102 - clip negative "after" values to 0 in AnyEvent::Impl::Event
103 to avoid spamming out warning messages.
104 - fix Qt timers without interval.
105 - avoid Qt zero-timeout special case, in old libqt's.
106
1074.352 Mon Apr 20 16:31:11 CEST 2009
108 - fix AnyEvent::Strict error messages for child watchers.
109 - fix/update Makefile.PL "recommends" versions.
110 - add AnyEvent->now_update.
111
1124.351 Sat Apr 11 07:56:14 CEST 2009
113 - actually make the signal pipe work under win32.
114 - localise $! in signal handler to avoid changing $!, although
115 perl itself does not seem to save/restore errno either.
116 - set the cloexec flag on the signal pipe (normally set by perl too).
117
1184.35 Fri Mar 27 11:48:20 CET 2009
119 - event models relying on AnyEvent's signal watcher emulation did
120 invoke the callback asynchronously, contradicting documentation
121 and causing signals to get lost (this includes AnyEvent's own
122 event loop). AnyEvent now uses the standard pipe trick to make
123 callback execution synchronous to the event loop.
124 - AnyEvent::Handle didn't free TLS context data on DESTROY
125 (patch by Pavel Shaydo).
126 - work around the ever-incompatibly-changing API of MakeMaker.
127 - document that changing global variables without restoring them
128 is a bad idea in Perl (noted by Adam Rosenstein).
129 - AnyEvent::Strict now barfs if ->io is passed a file.
130
1314.34 Thu Feb 12 18:32:45 CET 2009
132 - separately buffer TLS read data, as otherwise the read queue could
133 deadlock as receiving data is not expected while draining the
134 read queue (which cna only happen with TLS).
135 - raise EBADMSG error on JSON decoding errors.
136 - fix some minor manpage bugs (reported by Maximilian Gaß).
137 - speed up select bitmask parsing quite a bit in the pure perl
138 backend.
139 - use CORE::select instead of just select in AnyEvent::Impl::Perl.
140
1414.331 Tue Jan 6 21:07:25 CET 2009
142 - socketpair fails on many vista machines because vista has
143 completely broken accept/getpeername and getsockname functions,
144 so we provide our own socketpair emulation that kind of works
145 (AnyEvent::Util::portable_pipe).
146 - new function: AnyEvent::Util::portable_socketpair.
147 - take advantage of the Guard module if it exists.
148
1494.33 Fri Nov 21 02:35:40 CET 2008
150 - AnyEvent::Strict did errornously flag a fileno of 0 as
151 illegal.
152 - reduce memory usage and slightly speed up the pure perl backend
153 by only storing the file descriptor, not the file handle.
154 - add missing autocork method to AnyEvent::Handle (reported
155 by Adam Rosenstein).
156 - AnyEvent::DNS->resolve errornously documented an $rcode result
157 argument, but there isn't (spotted by Henrik Krohns).
158 - the naked truth about Tk - it's basically unmaintained.
159
1604.32 Mon Nov 3 22:46:32 CET 2008
161 - fix AnyEvent::Socket::resolve_sockaddr to properly support
162 unix sockets again and choose a proper default for
163 the socket type.
164 - fix call to resolve_sockaddr in tcp_connect.
165
1664.31 Thu Oct 30 04:41:48 CET 2008
167 - implemented AnyEvent::Handle->destroy method.
168 - hint about unexpected effects in TLS mode.
169 - speed up AnyEvent::Impl::Perl by using more arrays
170 instead of hashes without the slightest loss of readability :)
171 - work around a perl argument refcounting bug.
172 - with some perl patches applied, AnyEvent now seems leak-free.
173
1744.3 Fri Oct 3 09:18:43 CEST 2008
175 - AnyEvent will now install a no-op signal handler for SIGPIPE,
176 unless one has been installed already.
177 - warn about not loaidng AnyEvent::Impl::POE early enough
178 (patch by Adam Rosenstein).
179 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
180 - fix a bug in where in SSL connect mode, the
181 client would first wait for some data by the server and
182 otherwise hang. (reported and analyzed in an absolutely
183 exemplary manner by Adam Rosenstein).
184 - fix a bug in where SSL EOF would not be treated
185 as stream EOF, putting the connection into a hung state.
186 (reported and analyzed in an absolutely exemplary manner by Adam
187 Rosenstein).
188 - fix a potential segfault when the TLS context
189 would go missing in a read callback (e.g. due to stoptls) -
190 Net::SSLeay of course makes no type checking whatsoever.
191 - AnyEvent::Handle will not stop the read watcher in TLS mode.
192 - AnyEvent::Handle->stoptls will send a TLS close notify
193 instead of simply destroying the stream now.
194 - fix a bug where large blocks of data written in TLS mode
195 would not be sent unless triggered by receives.
196 - on_drain will now take the tls write buffer into account.
197 - SSL operations have been streamlined a bit and should be faster
198 now, more to come, though.
199 - added a FAQ section, will document nontrivial issues in there.
200
2014.234 Mon Sep 29 04:08:13 CEST 2008
202 - fix child watcher documentation: only child exits will be reported,
203 no trace events.
204 - mention SIGPIPE in AnyEvent::Handle.
205 - perl backend will now use POSIX::times as monotonic clock
206 when available and the monotonic clock option is not.
207 - run even without Time::HiRes in some cases now, but do not
208 provide sub-second accuracy (all *supported* perl versions have
209 Time::HiRes).
210
2114.233 Fri Aug 22 01:48:05 CEST 2008
212 - fix a bug in the testsuite, causing a hang.
213 - clarified lots of AnyEvent::Handle constructor arguments.
214
2154.232 Thu Aug 21 20:44:25 CEST 2008
216 - fix a bug in AnyEvent::Handle that could cause two fatal error
217 callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
218 (testcase by Leon Brocard).
219 - clarified on_eof/on_error documentation a bit.
220
2214.231 Tue Jul 29 13:12:15 CEST 2008
222 - remove some debugging code left in AnyEvent::Util::fork_call
223 (and no, it's impossible to implement with the broken windows
224 perls without resource leaks or worse).
225
2264.23 Tue Jul 29 12:19:59 CEST 2008
227 - document the first parameter passed to condvar callbacks to be
228 the callback.
229 - add AnyEvent::Socket::{ntoa,aton} aliases.
230 - optimize the AE::Handle->push_read (line) for the default
231 eol marker.
232 - optimize push_read (packstring|storable) for small packets.
233 - invoke on_error callback when no on_eof callback is set.
234 - fix a bug in push_read (storable) of unknown impact.
235
2364.22 Sun Jul 20 16:34:13 CEST 2008
237 - new function AnyEvent::Socket::parse_hostport.
238 - as the bulkheads at microsoft can't even get getprotobyname reliably
239 working on their shitty fucking broken os we need to hardcode
240 some common protocol numbers in AnyEvent::Socket. How can
241 people even bother with such a pile of shit as windows.
242
2434.21 Thu Jul 17 14:40:05 CEST 2008
244 - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
245 which is incompatible to previous invocation syntax.
246 - work around more windows perl bugs in fork_call. I cannot imagine
247 why anybody would bother implementing fork in such an obviously
248 unusable way.
249 - avoid calling $do_retry if the request has already finished in
250 AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
251 K. Sharifulin).
252
2534.2 Sat Jul 12 22:42:11 CEST 2008
254 - support an "interval" argument for repeating timers.
255 - fix a bug in the pure perl event loop that caused timers to
256 be delayed under some circumstances.
257 - implement optional argument checking via PERL_ANYEVENT_STRICT.
258 - not importing anything from Event causes it to malfunction
259 and not use Time::HiRes, work around this bug.
260 - more bug workarounds against the endlessly broken Tk module,
261 seems to work now on 32 bit machines, but less so on 64 bit.
262 - minor optimisations applied to most backends.
263
2644.161 Fri Jul 4 14:24:48 CEST 2008
265 - fixed the t/handle/02_write.t, it read after write, with the
266 assumption that all data could be written before read
267 (reported by Jim Razmus).
268
2694.160 Thu Jul 3 04:02:21 CEST 2008
270 - re-registering signal watchers after unregistering one did
271 not work if a backend falls back on AnyEvent's default
272 implementation (also affected child watchers).
273 - new AnyEvent::Handle options: autocork and no_delay.
274
2754.152 Sun Jun 22 14:15:44 CEST 2008
276 - allow for 32-bit perls that implement shifts differently
277 on different architectures in parse_ipv4 (reported and
278 analysed by Keiichi DAIBA).
279
2804.151 Fri Jun 6 17:34:24 CEST 2008
281 - make sure specifying _only_ on_read and never pushing reads
282 works.
283
2844.15 Fri Jun 6 13:00:46 CEST 2008
285 - the pure perl backend would keep some watchers alive when more than
286 one watcher was registered for the same fd.
287 - new "packstring" and "storable" read and write types
288 for AnyEvent::Handle.
289 - allow on_eof handler to be called after on_error with EPIPE returns.
290 - do not immediately call on_read callback in handle constructor.
291
2924.14 Thu Jun 5 20:29:31 CEST 2008
293 - Fixed a bug in DNS SRV priority sorting.
294 - AnyEvent::Util::guard now reports runtime errors while
295 executing the guard block as warnings.
296 - handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.
297
2984.13 Thu Jun 5 00:47:59 CEST 2008
299 - AnyEvent::DNS only followed cname chains with length 2,
300 contrary to documentation. bumped it up to 10, thanks to
301 microsoft, the current broken-dns-config-king.
302 - AnyEvent::DNS didn't check for socket return status
303 but instead relied on perl not creating filehandles in that
304 case - too bad it gives you a bogus file handle (reported
305 and analysed by Vladimir Timofeev).
306 - fix queue management logic in AnyEvent::Handle:
307 when on_read was registered, the queue was empty
308 and no progress could be made AnyEvent::Handle would
309 enter an endless loop.
310 - correctly start reading again when the handle became
311 busy again after idling.
312 - correctly treat tls shut-downs as EOF condition
313 (for the time being, would be nice to have a callback for that).
314 - correctly call eof callback under all conditions
315 (hopefully).
316 - the timeout callback did not expect that $self can go
317 away any time.
318
3194.12 Tue Jun 3 10:58:04 CEST 2008
320 - include AnyEvent::Intro, a tutorial for anyevent,
321 anyevent::socket and anyevent::handle.
322 - allow more options in on_error.
323
3244.11 Fri May 30 23:42:25 CEST 2008
325 - INCOMPATIBLE CHANGE: replace ptr by real PTR lookup, provide
326 reverse_lookup and reverse_verify to replace it, support
327 v4mapped and v4compat addresses.
328 - provide more documentation for the resolver class.
329 - really replace longest run of :0: by :: in format_address,
330 also properly convert :: and ::1 again.
331 - support NAPTR record name and decode it.
332 - implement random weight sampling for SRV records, as per
333 rfc 2782.
334 - correctly abort on srv-record targets of ".".
335 - added AnyEvent::DNS::wait_for_slot.
336 - in the unlikely event of a virtual circuit connection
337 being invalidated by a delayed udp reply, AnyEvent::DNS
338 could die. this has been fixed.
339 - plug a probable memleak in the DNS vc code.
340 - use configured timeout also for VC request phase.
341 - implement timeout and max_outstanding methods
342 for resolver class.
343 - update version numbers in all modules.
344
3454.1 Thu May 29 05:45:40 CEST 2008
346 - INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address
347 which mirrors their purpose better (old names still available
348 for a while). Also moved AnyEvent::DNS::addr to
349 AnyEvent::Socket::resolve_sockaddr.
350 - implement AnyEvent->time and AnyEvent->now.
351 - fix IPv6 support in pack_sockaddr.
352 - officially un-experimentalise all newly introduced code.
353 - support unix domain sockets everywhere by specifying
354 a host of "unix/" and the pathname as service.
355 - implement an activity timeout in AnyEvent::Handle.
356 - added a regex read type to AnyEvent::Handle.
357 - added a json read/write type to AnyEvent::Handle.
358 - always croak in on_error in AnyEvent::Handle.
359 - document how to subclass AnyEvent::Handle.
360 - implement AnyEvent::Util::fork_call.
361 - add support for IPv6 nameservers and nameserver statements.
362 - work around _yet_ _another_ windows perl bug in where empty
363 select masks cause errors in the pure perl backend (this
364 workaround cannot be implemented for the other event loops,
365 but EV also works around this).
366 - supply AnyEvent::Socket::address_type and make good use of it.
367 - clarify and fix the Handle documentation w.r.t $self vs. $handle
368 vs. callback arguments.
369 - add some recommends to the META.yml.
370
3714.05 Mon May 26 19:44:06 CEST 2008
372 - some platforms ignore the rfc and prepend an extra sa_len member to
373 the sockaddr structure, cater for those. also use sockaddr_family,
374 didn't know it was there, but comes in handy for the workaround.
375 - undo the import WIN32 hack.
376
3774.04 Mon May 26 08:03:31 CEST 2008
378 - try to work around yet another windows bug: failed connects are reported
379 as if it were out-of-band data. windows users: you suck. Only
380 EV, Glib, Event and the pure perl backend can handle this condition.
381 - optimize write algorithm in AnyEvent::Handle.
382 - properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
383 - tcp_connect now properly iterates through all targets.
384 - check wether IPv6 sockets can actually be created, otherwise, disable ipv6
385 support entirely. also hardcode some AF_INET6 constants for the
386 sake of perl 5.8.
387 - vastly improved nameserver/suffix detection algorithm for windows
388 (still a hack...)
389 - try to use a fallback dns server if no dns servers could be found.
390 - splatter around some local $SIG{__DIE__}'s to work around bad
391 die handlers.
392
3934.03 Sun May 25 05:05:57 CEST 2008
394 - work around perl bugs on windows, where perl returns undocumented
395 error codes for sysread, syswrite etc.
396 - fix AnyEvent::Handle::unshift_read to really unshift and not push.
397 - AnyEvent::Handle could sometimes stumble over 0-byte writes.
398 - fix unpack_sockaddr, now works for AF_INET6 sockaddr's.
399 - updated documentation.
400 - lots of workarounds for perl 5.8 quirks.
401 - implement a more flexible type system for both reads and writes
402 in AnyEvent::Handle.
403 - support IPv6 in tcp_server.
404 - pass local hostname and port to the prepare callback in tcp_server.
405 - make types extendable in AnyEvent::Handle.
406 - croak, not die, in AnyEvent::Handle;
407
4084.0 Sat May 24 19:58:08 CEST 2008
409 - added (experimental) AnyEvent::DNS module.
410 - added (experimental) AnyEvent::Socket module.
411 - added (experiemntal) support for TLS/SSL in AnyEvent::Handle.
412 - make condvar->end call ->send as documented.
413 - make condvar constructor support the documented cb => argument.
414 - overload condvars so you can use them instead of code references.
415 - support more of the POSIX forms instead of a pure dotted quad for
416 verbatim ip addresses.
417 - AnyEvent::Socket::inet_aton will use AnyEvent::DNS now and not fork anymore.
418 - try very hard not to freeze on broken windows perls.
419 - make on_eof optional in AnyEvent::Handle.
420 - support service names in tcp_connect and tcp_server.
421 - work around netbsd/openbsd bug causing unix sockets not to
422 become writable until empty.
423 - only make a dummy read for error detection when getpeername
424 returns ENOTCONN.
425 - defend AnyEvent::Util::inet_aton against Coro::LWP's brutal
426 override.
427 - new AnyEvent::Guard::cancel.
428
4293.5 Sat May 17 23:17:14 CEST 2008
430 - gracefully deal with systems not defining CLOCK_MONOTONIC
431 (as opposed to not supporting the clock itself, which worked in 3.41).
432 - added AnyEvent::Util::tcp_connect and AnyEvent::Util::tcp_server
433 helpers, to replace the ill-designed AnyEvent::Socket class.
434 - added some examples (eg/connect, eg/handle).
435 - added AnyEvent::Util::guard.
436 - AnyEvent::Util now exports most of its functions.
437 - fixed a bug in *_read_chunk, where the callback was called with $self as
438 first and second argument.
439 - simplified and fixed regex handling in AnyEvent::Handle::*_read_line.
440 - fix manpage condvars examples to use new syntax.
441 - considerably improve inet_aton with EV::ADNS backend to support
442 cname chains (common dns configuration bug, e.g. with www.google.de)
443 and aaaa records if no a record could be found.
444
4453.41 Sun May 11 19:53:13 CEST 2008
446 - work around a bug in perl 5.8.8's local. Reported by Yi Ma Mao.
447
4483.4 Sun May 11 00:29:25 CEST 2008
449 - complete re-implementation of condvars with a hopefully much more useful
450 API (backward compatible functions exist but are undocumented).
451 - AnyEvent::Handle fully rewritten with a hopefully more powerful API
452 (still subject to change).
4 - take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl. 453 - take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl.
454 - provide AnyEvent::post_detect and @AnyEvent::post_detect, which
455 allows module authors to avoid forcing event loop detection.
456 (used by Coro::AIO, Coro::BDB, Coro::AnyEvent for example).
457 - remove coro backends: Coro now provides generic support for AnyEvent
