34.160 35.2 Mon Sep 14 07:04:49 CEST 2009
4 - INCOMPATIBLE CHANGE: do no longer support register_read_type
5 and register_write_type in AnyEvent::Handle, instead support
6 package names (the facility was mostly abused).
7 - implement "packagename-as-read/write type" support in
8 AnyEvent::Handle.
9 - AnyEvent::Handle: new options "keepalive" and "oobinline".
10 - oobinline set by default to avoid security issues.
11 - the pure-perl event loop backend wrongly detected times() fallback
12 support (spotted by Pavel Boldin).
13
145.12 Tue Sep 1 20:26:50 CEST 2009
15 - be more lenient when parsing resolv.conf files, as some people
16 use hashmarks as comment indicator inside directives (reported
17 by Michael S. Fischer).
18 - use same set of warnings as common::sense 2.0.
19 - fix a potential 32 bit overflow issue due to perl having problems
20 with large hex constants in the Perl backend.
21 - do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS
22 by default.
23 - fix some prototypes.
24 - (optionally) require Async::Interrupt 1.02.
25 - replace opendns fallbacks by verizon/level3 public dns servers.
26
275.112 Fri Aug 21 13:59:04 CEST 2009
28 - AnyEvent::Handle could cause hard crashes in Net::SSLeay when
29 using starttls with an illegal/uncreatable tls context.
30 - port to broken win32 perls.
31
325.111 Sun Aug 16 18:44:36 CEST 2009
33 - perl errornously requires sockaddr_un structures returned by the
34 kernel to have a specific length. work around this bug by padding
35 sockaddr_un structures (found to fail on OS X, as perl only uses
36 the correct code for GNU/Linux, but likely to fail on other
37 OSes as well).
38
395.11 Wed Aug 12 17:49:37 CEST 2009
40 - fixed a bug in run_cmd with input from filename.
41 - create a json coder object when none is given in write direction
42 to reduce dependency on JSON.
43
445.1 Tue Aug 11 03:17:32 CEST 2009
45 - tcp_connect now reports the correct error in $!, not an unrelated
46 one (was broken since 4.91).
47 - AE::Handle did not properly clear rtimeout/wtimeout watchers
48 when retrying a tcp_connect.
49 - new functions: AnyEvent::Util::run_cmd and close_all_fds_except.
50 - fixed wrong documentation in AE::Socket.
51
525.01 Mon Aug 10 03:16:32 CEST 2009
53 - last release broke EV child watchers :/.
54
555.0 Sun Aug 9 17:32:09 CEST 2009
56 - officially introduce and document the AE API.
57 - lowering the timeout at runtime did not have immediate effect
58 in AnyEvent::Handle.
59 - AE::Handle now has separate and independent read and write timeout
60 settings.
61 - probe for Guard module when AnyEvent::Util is loaded, not at
62 runtime (Event doesn't like eval "use" from callbacks, and it avoids
63 exporting the probe function).
64 - Impl::IOAsync's io watchers did not use the filehandle emulation
65 code to work around it's watcher limits.
66 - work around IO::Async's problems with overloaded objects.
67 - try to disable wearnings inside IO::Async, it's just too buggy.
68 - do no longer use Event by default, only EV or Perl, Event is too buggy.
69 - hackishly provide fast AE:: interface when EV or Perl is the backend.
70 - inherit VERSION from AnyEvent::VERSION in most modules.
71
724.91 Thu Aug 6 15:42:45 CEST 2009
73 - AE::Handle::starttls could get out of sync when the read buffer
74 already contains some TLS handshake.
75 - AE::Handle did not properly free the TLS session, causing bigger
76 memory leaks in Net::SSLeay than expected (reported by toaster).
77 - AE::Socket::tcp_connect will now artificially delay invoking
78 the callback to avoid returning after invoking the callback.
79 - convert many internal watcher uses to AE API.
80
814.9 Sat Aug 1 11:07:01 CEST 2009
82 - Glib silently fails when registering a timeout with
83 a negative value, so avoid that.
84 - call condvar callback immediately when it is set
85 after the condition is already signalled.
86 - check rbuf_max condition only after trying to consume
87 data.
88 - normalise signal numbers to names when using the ae's
89 signal handling, but do not document this (yet).
90 - pure perl signal emulation did not properly set nonblocking
91 mode on the signal pipe on win32 (this is unlikely to have caused
92 any issues).
93 - new module: AnyEvent::Debug.
94 - AnyEvent::Strict now checks that a signal was specified
95 by name (not name or number).
96 - reduce memory footprint in typical cases by ~50kb by
97 only compiling signal code when necessary.
98 - add AnyEvent::Handle->rbuf_max.
99 - grab the AE namespace for future new API, implement stubs for
100 said future/alternative API.
101 - new function: AnyEvent::Socket::format_hostport.
102
1034.881 Tue Jul 28 12:51:53 CEST 2009
104 - work around a bug in local in pre-5.10 perls, causing
105 AnyEvent::Handle to recurse when it should not
106 (analyzed by elmex).
107
1084.88 Tue Jul 28 04:04:37 CEST 2009
109 - re-bless the handle into a dummy package after calling
110 AnyEvent::Handle::destroy, so the user does not need to check
111 for errors after every push_write etc.
112 - do not attempt to run t/02_signals.t on obviously broken
113 platforms.
114
1154.87 Sun Jul 26 02:06:16 CEST 2009
116 - do not attempt to linger when there is no longer a valid fh.
117 - enforce tls mode to be either accept or connect, do not simply
118 segfault in Net::SSLeay.
119 - AnyEvent::Handle can now call tcp_connect itself (new parameters
120 connect, on_prepare, on_connect and on_connect_error). Updated
121 tutorial accordingly.
122 - add AnyEvent::Impl::Irssi backend.
123
1244.86 Mon Jul 20 23:52:29 CEST 2009
125 - since the verbose warning is not enough, explicitly document
126 that versions before 1.33 of Net::SSLeay are not secure.
127 - work around signal handling races in Event and (...) Event::Lib.
128 - try to align signal-race timer to full-second boundaries.
129 - work around Tk not liking negative timeouts.
130 - don't complain of different grades of environmental unfriendlyness
131 in IO::Async.
132
1334.85 Sat Jul 18 06:16:14 CEST 2009
134 - nail the signal race problem in perl once and for all
135 (see $AnyEvent::MAX_SIGNAL_LATENCY).
136 - take advantage of Async::Interrupt if it is available.
137 - load Time::HiRes and Guard modules on demand only.
138 - add optional/recommended modules section to AnyEvent
139 documentation.
140 - reduce memory usage considerably (and reduce startup penalty)
141 by not using "strict", "warnings" and "overload" modules.
142 - work around buggy windows/openbsd perls and provide EBADMSG
143 and EPROTO ourselves when missing.
144 - improve perl 5.6 compatibility of the core event loop.
145 - made Net::SSLeay version 1.33 a soft requirement.
146
1474.83 Fri Jul 17 16:56:26 CEST 2009
148 - implement AnyEvent::Socket::getprotobyname.
149 - AnyEvent::CondVar's will now detect recursive blocking
150 waits and will croak, as too many people fall into
151 this trap.
152 - AnyEvent::Handle will now call ->destroy on itself after
153 executing the on_error callback, instead of doing some
154 half-baked internal shutdown, for fatal errors.
155 - clarify on_eof behaviour w.r.t. the read queue and
156 on_read callbacks.
157 - ignore some possible spurious wake-ups in tcp_connect.
158
1594.82 Sat Jul 11 00:34:55 CEST 2009
160 - POE and Event backends didn't accept some callable objects as
161 callbacks.
162 - use Config module instead of POSIX module to detect signal names
163 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
164 module doesn't even have all POSIX signals :/.
165 - use more workarounds around the many refcnt/corruption bugs in
166 Event::Lib.
167 - work around a race condition in perl's select, causing t/03_child.t
168 to rarely fail.
169
1704.81 Thu Jul 9 10:30:30 CEST 2009
171 - AnyEvent::Handle didn't properly diagnose write errors
172 (it expected -1 from syswrite, how lame... :).
173 - support file descriptors in addition to file handles
174 in AnyEvent->io.
175 - new env variables: PERL_ANYEVENT_RESOLV_CONF,
176 PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
177 and PERL_ANYEVENT_CA_PATH.
178 - provide a sensible synopsis section for AnyEvent::TLS.
179 - add a "supported backends" section to the manpage.
180 - added simple io watcher test to testsuite, using a
181 portable_socketpair.
182 - tried to improve the stability of the Event::Lib backend,
183 YMMV.
184
1854.8 Mon Jul 6 23:45:16 CEST 2009
186 - AnyEvent::DNS did not properly follow CNAME records with
187 uppercase targets.
188 - AnyEvent::DNS would errornously return AAAA records
189 with v4 mapped addresses (a faulty record) as ipv4 addresses,
190 causing AnyEvent::Socket to throw an exception.
191 - added new module AnyEvent::TLS for easier SSL/TLS context
192 creation, with many options including hostname verification,
193 secure default configuration, lots of documentation and,
194 predefined diffie-hellman keys for perfect forward security
195 and much more. get it while it's still fresh!
196 - use AnyEvent::TLS in AnyEvent::Handle for context management.
197 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
198 so AnyEvent::Socket users have smaller memory footprint
199 in the common case.
200 - add AnyEvent::Handle->push_shutdown method.
201 - add an additional error message parameter to AnyEvent::Handle's
202 on_error callback (for TLS, $! is still available).
203 - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
204 - make AnyEvent::Handle more robust against early conenction
205 failures (during new), and return C<undef> in that case
206 from the constructor.
207 - AnyEvent::Handle will now try to load only JSON::XS first,
208 then fall back to JSON.
209 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
210 and because it was documented that way.
211
2124.451 Fri Jul 3 00:28:58 CEST 2009
213 - do not clear rbuf when shutting down an AnyEvent::Handle
214 object - doing so breaks AnyEvent::HTTP.
215
2164.45 Mon Jun 29 22:59:26 CEST 2009
217 - a write error could cause AnyEvent::Handle to create
218 an I/O watcher with an undefined $fh.
219 - special-case mapped ipv4 addresses in both
220 AnyEvent::Socket::format_address and parse_address,
221 to treat them just like ipv4 addresses.
222 - updated and overhauled the AnyEvent::Intro doc.
223 - implement AnyEvent::Socket::format_ipv4/ipv6.
224 - slightly speed up portable_pipe/socketpair.
225 - expand condvar begin/end documentation.
226
2274.42 Fri Jun 26 08:32:18 CEST 2009
228 - preliminary and neccesarily incomplete support for IO::Async.
229 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
230 case it was set to IGNORE, to ensure we can catch child statuses
231 even when the calling env acts stupidly.
232 - updated benchmarks with IO::Async, which performs very well.
233
2344.412 Wed Jun 24 01:35:57 CEST 2009
235 - support an "untaint" attribute for AnyEvent::DNS
236 and set it on the default resolver.
237 - implement and document AnyEvent::Impl::Perl::loop.
238 - remove all anyevent-env variables from %ENV
239 when running in tainted mode.
240 - mention and extend the IO::Lambda benchmark.
241
2424.411 Sun Jun 7 18:48:02 CEST 2009
243 - do not try to use F_SETFD on windows.
244
2454.41 Thu May 14 06:40:11 CEST 2009
246 - work around issues in older perls (5.8.0?) when
247 a signal handler is deleted from the %SIG hash.
248 - use POSIX::_exit in child test, to avoid running
249 destructors.
250 - speed up CHLD handling by relying on SIGCHLD being
251 synchronously delivered, even when we roll our own
252 implementation.
253 - AnyEvent::DNS: add the "dname" resource record name
254 for cosmetic reasons.
255
2564.4 Sun Apr 26 20:12:33 CEST 2009
257 - implemented idle watchers, where applicable.
258 - AnyEvent->time died when Event backend was in use.
259 - fix a memleak in the Tk backend.
260 - sped up Tk timer handling.
261 - clip negative "after" values to 0 in AnyEvent::Impl::Event
262 to avoid spamming out warning messages.
263 - fix Qt timers without interval.
264 - avoid Qt zero-timeout special case, in old libqt's.
265
2664.352 Mon Apr 20 16:31:11 CEST 2009
267 - fix AnyEvent::Strict error messages for child watchers.
268 - fix/update Makefile.PL "recommends" versions.
269 - add AnyEvent->now_update.
270
2714.351 Sat Apr 11 07:56:14 CEST 2009
272 - actually make the signal pipe work under win32.
273 - localise $! in signal handler to avoid changing $!, although
274 perl itself does not seem to save/restore errno either.
275 - set the cloexec flag on the signal pipe (normally set by perl too).
276
2774.35 Fri Mar 27 11:48:20 CET 2009
278 - event models relying on AnyEvent's signal watcher emulation did
279 invoke the callback asynchronously, contradicting documentation
280 and causing signals to get lost (this includes AnyEvent's own
281 event loop). AnyEvent now uses the standard pipe trick to make
282 callback execution synchronous to the event loop.
283 - AnyEvent::Handle didn't free TLS context data on DESTROY
284 (patch by Pavel Shaydo).
285 - work around the ever-incompatibly-changing API of MakeMaker.
286 - document that changing global variables without restoring them
287 is a bad idea in Perl (noted by Adam Rosenstein).
288 - AnyEvent::Strict now barfs if ->io is passed a file.
289
2904.34 Thu Feb 12 18:32:45 CET 2009
291 - separately buffer TLS read data, as otherwise the read queue could
292 deadlock as receiving data is not expected while draining the
293 read queue (which cna only happen with TLS).
294 - raise EBADMSG error on JSON decoding errors.
295 - fix some minor manpage bugs (reported by Maximilian Gaß).
296 - speed up select bitmask parsing quite a bit in the pure perl
297 backend.
298 - use CORE::select instead of just select in AnyEvent::Impl::Perl.
299
3004.331 Tue Jan 6 21:07:25 CET 2009
301 - socketpair fails on many vista machines because vista has
302 completely broken accept/getpeername and getsockname functions,
303 so we provide our own socketpair emulation that kind of works
304 (AnyEvent::Util::portable_pipe).
305 - new function: AnyEvent::Util::portable_socketpair.
306 - take advantage of the Guard module if it exists.
307
3084.33 Fri Nov 21 02:35:40 CET 2008
309 - AnyEvent::Strict did errornously flag a fileno of 0 as
310 illegal.
311 - reduce memory usage and slightly speed up the pure perl backend
312 by only storing the file descriptor, not the file handle.
313 - add missing autocork method to AnyEvent::Handle (reported
314 by Adam Rosenstein).
315 - AnyEvent::DNS->resolve errornously documented an $rcode result
316 argument, but there isn't (spotted by Henrik Krohns).
317 - the naked truth about Tk - it's basically unmaintained.
318
3194.32 Mon Nov 3 22:46:32 CET 2008
320 - fix AnyEvent::Socket::resolve_sockaddr to properly support
321 unix sockets again and choose a proper default for
322 the socket type.
323 - fix call to resolve_sockaddr in tcp_connect.
324
3254.31 Thu Oct 30 04:41:48 CET 2008
326 - implemented AnyEvent::Handle->destroy method.
327 - hint about unexpected effects in TLS mode.
328 - speed up AnyEvent::Impl::Perl by using more arrays
329 instead of hashes without the slightest loss of readability :)
330 - work around a perl argument refcounting bug.
331 - with some perl patches applied, AnyEvent now seems leak-free.
332
3334.3 Fri Oct 3 09:18:43 CEST 2008
334 - AnyEvent will now install a no-op signal handler for SIGPIPE,
335 unless one has been installed already.
336 - warn about not loaidng AnyEvent::Impl::POE early enough
337 (patch by Adam Rosenstein).
338 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
339 - fix a bug in where in SSL connect mode, the
340 client would first wait for some data by the server and
341 otherwise hang. (reported and analyzed in an absolutely
342 exemplary manner by Adam Rosenstein).
343 - fix a bug in where SSL EOF would not be treated
344 as stream EOF, putting the connection into a hung state.
345 (reported and analyzed in an absolutely exemplary manner by Adam
346 Rosenstein).
347 - fix a potential segfault when the TLS context
348 would go missing in a read callback (e.g. due to stoptls) -
349 Net::SSLeay of course makes no type checking whatsoever.
350 - AnyEvent::Handle will not stop the read watcher in TLS mode.
351 - AnyEvent::Handle->stoptls will send a TLS close notify
352 instead of simply destroying the stream now.
353 - fix a bug where large blocks of data written in TLS mode
354 would not be sent unless triggered by receives.
355 - on_drain will now take the tls write buffer into account.
356 - SSL operations have been streamlined a bit and should be faster
357 now, more to come, though.
358 - added a FAQ section, will document nontrivial issues in there.
359
3604.234 Mon Sep 29 04:08:13 CEST 2008
361 - fix child watcher documentation: only child exits will be reported,
362 no trace events.
363 - mention SIGPIPE in AnyEvent::Handle.
364 - perl backend will now use POSIX::times as monotonic clock
365 when available and the monotonic clock option is not.
366 - run even without Time::HiRes in some cases now, but do not
367 provide sub-second accuracy (all *supported* perl versions have
368 Time::HiRes).
369
3704.233 Fri Aug 22 01:48:05 CEST 2008
371 - fix a bug in the testsuite, causing a hang.
372 - clarified lots of AnyEvent::Handle constructor arguments.
373
3744.232 Thu Aug 21 20:44:25 CEST 2008
375 - fix a bug in AnyEvent::Handle that could cause two fatal error
376 callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
377 (testcase by Leon Brocard).
378 - clarified on_eof/on_error documentation a bit.
379
3804.231 Tue Jul 29 13:12:15 CEST 2008
381 - remove some debugging code left in AnyEvent::Util::fork_call
382 (and no, it's impossible to implement with the broken windows
383 perls without resource leaks or worse).
384
3854.23 Tue Jul 29 12:19:59 CEST 2008
386 - document the first parameter passed to condvar callbacks to be
387 the callback.
388 - add AnyEvent::Socket::{ntoa,aton} aliases.
389 - optimize the AE::Handle->push_read (line) for the default
390 eol marker.
391 - optimize push_read (packstring|storable) for small packets.
392 - invoke on_error callback when no on_eof callback is set.
393 - fix a bug in push_read (storable) of unknown impact.
394
3954.22 Sun Jul 20 16:34:13 CEST 2008
396 - new function AnyEvent::Socket::parse_hostport.
397 - as the bulkheads at microsoft can't even get getprotobyname reliably
398 working on their shitty fucking broken os we need to hardcode
399 some common protocol numbers in AnyEvent::Socket. How can
400 people even bother with such a pile of shit as windows.
401
4024.21 Thu Jul 17 14:40:05 CEST 2008
403 - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
404 which is incompatible to previous invocation syntax.
405 - work around more windows perl bugs in fork_call. I cannot imagine
406 why anybody would bother implementing fork in such an obviously
407 unusable way.
408 - avoid calling $do_retry if the request has already finished in
409 AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
410 K. Sharifulin).
411
4124.2 Sat Jul 12 22:42:11 CEST 2008
413 - support an "interval" argument for repeating timers.
414 - fix a bug in the pure perl event loop that caused timers to
415 be delayed under some circumstances.
416 - implement optional argument checking via PERL_ANYEVENT_STRICT.
417 - not importing anything from Event causes it to malfunction
418 and not use Time::HiRes, work around this bug.
419 - more bug workarounds against the endlessly broken Tk module,
420 seems to work now on 32 bit machines, but less so on 64 bit.
421 - minor optimisations applied to most backends.
422
4234.161 Fri Jul 4 14:24:48 CEST 2008
424 - fixed the t/handle/02_write.t, it read after write, with the
425 assumption that all data could be written before read
426 (reported by Jim Razmus).
427
4284.160 Thu Jul 3 04:02:21 CEST 2008
429 - re-registering signal watchers after unregistering one did
430 not work if a backend falls back on AnyEvent's default
431 implementation (also affected child watchers).
4 - new AnyEvent::Handle options: autocork and no_delay. 432 - new AnyEvent::Handle options: autocork and no_delay.

64.152 Sun Jun 22 14:15:44 CEST 2008 4344.152 Sun Jun 22 14:15:44 CEST 2008
7 - allow for 32-bit perls that implement shifts differently 435 - allow for 32-bit perls that implement shifts differently
8 on different architectures in parse_ipv4 (reported and 436 on different architectures in parse_ipv4 (reported and
151 - support service names in tcp_connect and tcp_server. 579 - support service names in tcp_connect and tcp_server.
152 - work around netbsd/openbsd bug causing unix sockets not to 580 - work around netbsd/openbsd bug causing unix sockets not to

156 - defend AnyEvent::Util::inet_aton against Coro::LWP brutal 584 - defend AnyEvent::Util::inet_aton against Coro::LWP's brutal
157 override. 585 override.
158 - new AnyEvent::Guard::cancel. 586 - new AnyEvent::Guard::cancel.
