55.112 Fri Aug 21 13:59:04 CEST 2009
6 - AnyEvent::Handle could cause hard crashes in Net::SSLeay when
7 using starttls with an illegal/uncreatable tls context.
8 - port to broken win32 perls.
9
105.111 Sun Aug 16 18:44:36 CEST 2009
11 - perl errornously requires sockaddr_un structures returned by the
12 kernel to have a specific length. work around this bug by padding
13 sockaddr_un structures (found to fail on OS X, as perl only uses
14 the correct code for GNU/Linux, but likely to fail on other
15 OSes as well).
16
175.11 Wed Aug 12 17:49:37 CEST 2009
18 - fixed a bug in run_cmd with input from filename.
19 - create a json coder object when none is given in write direction
20 to reduce dependency on JSON.
21
225.1 Tue Aug 11 03:17:32 CEST 2009
23 - tcp_connect now reports the correct error in $!, not an unrelated
24 one (was broken since 4.91).
25 - AE::Handle did not properly clear rtimeout/wtimeout watchers
26 when retrying a tcp_connect.
27 - new functions: AnyEvent::Util::run_cmd and close_all_fds_except.
28 - fixed wrong documentation in AE::Socket.
29
305.01 Mon Aug 10 03:16:32 CEST 2009
31 - last release broke EV child watchers :/.
32
335.0 Sun Aug 9 17:32:09 CEST 2009
34 - officially introduce and document the AE API.
35 - lowering the timeout at runtime did not have immediate effect
36 in AnyEvent::Handle.
37 - AE::Handle now has separate and independent read and write timeout
38 settings.
39 - probe for Guard module when AnyEvent::Util is loaded, not at
40 runtime (Event doesn't like eval "use" from callbacks, and it avoids
41 exporting the probe function).
42 - Impl::IOAsync's io watchers did not use the filehandle emulation
43 code to work around it's watcher limits.
44 - work around IO::Async's problems with overloaded objects.
45 - try to disable wearnings inside IO::Async, it's just too buggy.
46 - do no longer use Event by default, only EV or Perl, Event is too buggy.
47 - hackishly provide fast AE:: interface when EV or Perl is the backend.
48 - inherit VERSION from AnyEvent::VERSION in most modules.
49
504.91 Thu Aug 6 15:42:45 CEST 2009
51 - AE::Handle::starttls could get out of sync when the read buffer
52 already contains some TLS handshake.
53 - AE::Handle did not properly free the TLS session, causing bigger
54 memory leaks in Net::SSLeay than expected (reported by toaster).
55 - AE::Socket::tcp_connect will now artificially delay invoking
56 the callback to avoid returning after invoking the callback.
57 - convert many internal watcher uses to AE API.
58
594.9 Sat Aug 1 11:07:01 CEST 2009
60 - Glib silently fails when registering a timeout with
61 a negative value, so avoid that.
62 - call condvar callback immediately when it is set
63 after the condition is already signalled.
64 - check rbuf_max condition only after trying to consume
65 data.
66 - normalise signal numbers to names when using the ae's
67 signal handling, but do not document this (yet).
68 - pure perl signal emulation did not properly set nonblocking
69 mode on the signal pipe on win32 (this is unlikely to have caused
70 any issues).
71 - new module: AnyEvent::Debug.
72 - AnyEvent::Strict now checks that a signal was specified
73 by name (not name or number).
74 - reduce memory footprint in typical cases by ~50kb by
75 only compiling signal code when necessary.
76 - add AnyEvent::Handle->rbuf_max.
77 - grab the AE namespace for future new API, implement stubs for
78 said future/alternative API.
79 - new function: AnyEvent::Socket::format_hostport.
80
814.881 Tue Jul 28 12:51:53 CEST 2009
82 - work around a bug in local in pre-5.10 perls, causing
83 AnyEvent::Handle to recurse when it should not
84 (analyzed by elmex).
85
864.88 Tue Jul 28 04:04:37 CEST 2009
87 - re-bless the handle into a dummy package after calling
88 AnyEvent::Handle::destroy, so the user does not need to check
89 for errors after every push_write etc.
90 - do not attempt to run t/02_signals.t on obviously broken
91 platforms.
92
934.87 Sun Jul 26 02:06:16 CEST 2009
94 - do not attempt to linger when there is no longer a valid fh.
95 - enforce tls mode to be either accept or connect, do not simply
96 segfault in Net::SSLeay.
97 - AnyEvent::Handle can now call tcp_connect itself (new parameters
98 connect, on_prepare, on_connect and on_connect_error). Updated
99 tutorial accordingly.
100 - add AnyEvent::Impl::Irssi backend.
101
1024.86 Mon Jul 20 23:52:29 CEST 2009
103 - since the verbose warning is not enough, explicitly document
104 that versions before 1.33 of Net::SSLeay are not secure.
105 - work around signal handling races in Event and (...) Event::Lib.
106 - try to align signal-race timer to full-second boundaries.
107 - work around Tk not liking negative timeouts.
108 - don't complain of different grades of environmental unfriendlyness
109 in IO::Async.
110
1114.85 Sat Jul 18 06:16:14 CEST 2009
112 - nail the signal race problem in perl once and for all
113 (see $AnyEvent::MAX_SIGNAL_LATENCY).
114 - take advantage of Async::Interrupt if it is available.
115 - load Time::HiRes and Guard modules on demand only.
116 - add optional/recommended modules section to AnyEvent
117 documentation.
118 - reduce memory usage considerably (and reduce startup penalty)
119 by not using "strict", "warnings" and "overload" modules.
120 - work around buggy windows/openbsd perls and provide EBADMSG
121 and EPROTO ourselves when missing.
122 - improve perl 5.6 compatibility of the core event loop.
123 - made Net::SSLeay version 1.33 a soft requirement.
124
1254.83 Fri Jul 17 16:56:26 CEST 2009
126 - implement AnyEvent::Socket::getprotobyname.
127 - AnyEvent::CondVar's will now detect recursive blocking
128 waits and will croak, as too many people fall into
129 this trap.
130 - AnyEvent::Handle will now call ->destroy on itself after
131 executing the on_error callback, instead of doing some
132 half-baked internal shutdown, for fatal errors.
133 - clarify on_eof behaviour w.r.t. the read queue and
134 on_read callbacks.
135 - ignore some possible spurious wake-ups in tcp_connect.
136
1374.82 Sat Jul 11 00:34:55 CEST 2009
138 - POE and Event backends didn't accept some callable objects as
139 callbacks.
140 - use Config module instead of POSIX module to detect signal names
141 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
142 module doesn't even have all POSIX signals :/.
143 - use more workarounds around the many refcnt/corruption bugs in
144 Event::Lib.
145 - work around a race condition in perl's select, causing t/03_child.t
146 to rarely fail.
147
1484.81 Thu Jul 9 10:30:30 CEST 2009
149 - AnyEvent::Handle didn't properly diagnose write errors
150 (it expected -1 from syswrite, how lame... :).
151 - support file descriptors in addition to file handles
152 in AnyEvent->io.
153 - new env variables: PERL_ANYEVENT_RESOLV_CONF,
154 PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
155 and PERL_ANYEVENT_CA_PATH.
156 - provide a sensible synopsis section for AnyEvent::TLS.
157 - add a "supported backends" section to the manpage.
158 - added simple io watcher test to testsuite, using a
159 portable_socketpair.
160 - tried to improve the stability of the Event::Lib backend,
161 YMMV.
162
1634.8 Mon Jul 6 23:45:16 CEST 2009
164 - AnyEvent::DNS did not properly follow CNAME records with
165 uppercase targets.
166 - AnyEvent::DNS would errornously return AAAA records
167 with v4 mapped addresses (a faulty record) as ipv4 addresses,
168 causing AnyEvent::Socket to throw an exception.
169 - added new module AnyEvent::TLS for easier SSL/TLS context
170 creation, with many options including hostname verification,
171 secure default configuration, lots of documentation and,
172 predefined diffie-hellman keys for perfect forward security
173 and much more. get it while it's still fresh!
174 - use AnyEvent::TLS in AnyEvent::Handle for context management.
175 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
176 so AnyEvent::Socket users have smaller memory footprint
177 in the common case.
178 - add AnyEvent::Handle->push_shutdown method.
179 - add an additional error message parameter to AnyEvent::Handle's
180 on_error callback (for TLS, $! is still available).
181 - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
182 - make AnyEvent::Handle more robust against early conenction
183 failures (during new), and return C<undef> in that case
184 from the constructor.
185 - AnyEvent::Handle will now try to load only JSON::XS first,
186 then fall back to JSON.
187 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
188 and because it was documented that way.
189
1904.451 Fri Jul 3 00:28:58 CEST 2009
191 - do not clear rbuf when shutting down an AnyEvent::Handle
192 object - doing so breaks AnyEvent::HTTP.
193
1944.45 Mon Jun 29 22:59:26 CEST 2009
195 - a write error could cause AnyEvent::Handle to create
196 an I/O watcher with an undefined $fh.
197 - special-case mapped ipv4 addresses in both
198 AnyEvent::Socket::format_address and parse_address,
199 to treat them just like ipv4 addresses.
200 - updated and overhauled the AnyEvent::Intro doc.
201 - implement AnyEvent::Socket::format_ipv4/ipv6.
202 - slightly speed up portable_pipe/socketpair.
203 - expand condvar begin/end documentation.
204
2054.42 Fri Jun 26 08:32:18 CEST 2009
206 - preliminary and neccesarily incomplete support for IO::Async.
207 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
208 case it was set to IGNORE, to ensure we can catch child statuses
209 even when the calling env acts stupidly.
210 - updated benchmarks with IO::Async, which performs very well.
211
2124.412 Wed Jun 24 01:35:57 CEST 2009
213 - support an "untaint" attribute for AnyEvent::DNS
214 and set it on the default resolver.
215 - implement and document AnyEvent::Impl::Perl::loop.
216 - remove all anyevent-env variables from %ENV
217 when running in tainted mode.
218 - mention and extend the IO::Lambda benchmark.
219
2204.411 Sun Jun 7 18:48:02 CEST 2009
221 - do not try to use F_SETFD on windows.
222
2234.41 Thu May 14 06:40:11 CEST 2009
224 - work around issues in older perls (5.8.0?) when
225 a signal handler is deleted from the %SIG hash.
226 - use POSIX::_exit in child test, to avoid running
227 destructors.
228 - speed up CHLD handling by relying on SIGCHLD being
229 synchronously delivered, even when we roll our own
230 implementation.
231 - AnyEvent::DNS: add the "dname" resource record name
232 for cosmetic reasons.
233
2344.4 Sun Apr 26 20:12:33 CEST 2009
235 - implemented idle watchers, where applicable.
236 - AnyEvent->time died when Event backend was in use.
237 - fix a memleak in the Tk backend.
238 - sped up Tk timer handling.
239 - clip negative "after" values to 0 in AnyEvent::Impl::Event
240 to avoid spamming out warning messages.
241 - fix Qt timers without interval.
242 - avoid Qt zero-timeout special case, in old libqt's.
243
2444.352 Mon Apr 20 16:31:11 CEST 2009
245 - fix AnyEvent::Strict error messages for child watchers.
246 - fix/update Makefile.PL "recommends" versions.
247 - add AnyEvent->now_update.
248
2494.351 Sat Apr 11 07:56:14 CEST 2009
250 - actually make the signal pipe work under win32.
251 - localise $! in signal handler to avoid changing $!, although
252 perl itself does not seem to save/restore errno either.
253 - set the cloexec flag on the signal pipe (normally set by perl too).
254
2554.35 Fri Mar 27 11:48:20 CET 2009
256 - event models relying on AnyEvent's signal watcher emulation did
257 invoke the callback asynchronously, contradicting documentation
258 and causing signals to get lost (this includes AnyEvent's own
259 event loop). AnyEvent now uses the standard pipe trick to make
260 callback execution synchronous to the event loop.
261 - AnyEvent::Handle didn't free TLS context data on DESTROY
262 (patch by Pavel Shaydo).
263 - work around the ever-incompatibly-changing API of MakeMaker.
264 - document that changing global variables without restoring them
265 is a bad idea in Perl (noted by Adam Rosenstein).
266 - AnyEvent::Strict now barfs if ->io is passed a file.
267
2684.34 Thu Feb 12 18:32:45 CET 2009
269 - separately buffer TLS read data, as otherwise the read queue could
270 deadlock as receiving data is not expected while draining the
271 read queue (which cna only happen with TLS).
272 - raise EBADMSG error on JSON decoding errors.
273 - fix some minor manpage bugs (reported by Maximilian Gaß).
274 - speed up select bitmask parsing quite a bit in the pure perl
275 backend.
276 - use CORE::select instead of just select in AnyEvent::Impl::Perl.
277
2784.331 Tue Jan 6 21:07:25 CET 2009
279 - socketpair fails on many vista machines because vista has
280 completely broken accept/getpeername and getsockname functions,
281 so we provide our own socketpair emulation that kind of works
282 (AnyEvent::Util::portable_pipe).
283 - new function: AnyEvent::Util::portable_socketpair.
284 - take advantage of the Guard module if it exists.
285
2864.33 Fri Nov 21 02:35:40 CET 2008
287 - AnyEvent::Strict did errornously flag a fileno of 0 as
288 illegal.
289 - reduce memory usage and slightly speed up the pure perl backend
290 by only storing the file descriptor, not the file handle.
291 - add missing autocork method to AnyEvent::Handle (reported
292 by Adam Rosenstein).
293 - AnyEvent::DNS->resolve errornously documented an $rcode result
294 argument, but there isn't (spotted by Henrik Krohns).
295 - the naked truth about Tk - it's basically unmaintained.
296
2974.32 Mon Nov 3 22:46:32 CET 2008
298 - fix AnyEvent::Socket::resolve_sockaddr to properly support
299 unix sockets again and choose a proper default for
300 the socket type.
301 - fix call to resolve_sockaddr in tcp_connect.
302
3034.31 Thu Oct 30 04:41:48 CET 2008
304 - implemented AnyEvent::Handle->destroy method.
305 - hint about unexpected effects in TLS mode.
306 - speed up AnyEvent::Impl::Perl by using more arrays
307 instead of hashes without the slightest loss of readability :)
308 - work around a perl argument refcounting bug.
309 - with some perl patches applied, AnyEvent now seems leak-free.
310
3114.3 Fri Oct 3 09:18:43 CEST 2008
312 - AnyEvent will now install a no-op signal handler for SIGPIPE,
313 unless one has been installed already.
314 - warn about not loaidng AnyEvent::Impl::POE early enough
315 (patch by Adam Rosenstein).
316 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
317 - fix a bug in where in SSL connect mode, the
318 client would first wait for some data by the server and
319 otherwise hang. (reported and analyzed in an absolutely
320 exemplary manner by Adam Rosenstein).
321 - fix a bug in where SSL EOF would not be treated
322 as stream EOF, putting the connection into a hung state.
323 (reported and analyzed in an absolutely exemplary manner by Adam
324 Rosenstein).
325 - fix a potential segfault when the TLS context
326 would go missing in a read callback (e.g. due to stoptls) -
327 Net::SSLeay of course makes no type checking whatsoever.
328 - AnyEvent::Handle will not stop the read watcher in TLS mode.
329 - AnyEvent::Handle->stoptls will send a TLS close notify
330 instead of simply destroying the stream now.
331 - fix a bug where large blocks of data written in TLS mode
332 would not be sent unless triggered by receives.
333 - on_drain will now take the tls write buffer into account.
334 - SSL operations have been streamlined a bit and should be faster
335 now, more to come, though.
336 - added a FAQ section, will document nontrivial issues in there.
337
3384.234 Mon Sep 29 04:08:13 CEST 2008
339 - fix child watcher documentation: only child exits will be reported,
340 no trace events.
341 - mention SIGPIPE in AnyEvent::Handle.
342 - perl backend will now use POSIX::times as monotonic clock
343 when available and the monotonic clock option is not.
344 - run even without Time::HiRes in some cases now, but do not
345 provide sub-second accuracy (all *supported* perl versions have
346 Time::HiRes).
347
3484.233 Fri Aug 22 01:48:05 CEST 2008
349 - fix a bug in the testsuite, causing a hang.
350 - clarified lots of AnyEvent::Handle constructor arguments.
351
3524.232 Thu Aug 21 20:44:25 CEST 2008
353 - fix a bug in AnyEvent::Handle that could cause two fatal error
354 callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
355 (testcase by Leon Brocard).
356 - clarified on_eof/on_error documentation a bit.
357
3584.231 Tue Jul 29 13:12:15 CEST 2008
359 - remove some debugging code left in AnyEvent::Util::fork_call
360 (and no, it's impossible to implement with the broken windows
361 perls without resource leaks or worse).
362
3634.23 Tue Jul 29 12:19:59 CEST 2008
364 - document the first parameter passed to condvar callbacks to be
365 the callback.
366 - add AnyEvent::Socket::{ntoa,aton} aliases.
367 - optimize the AE::Handle->push_read (line) for the default
368 eol marker.
369 - optimize push_read (packstring|storable) for small packets.
370 - invoke on_error callback when no on_eof callback is set.
371 - fix a bug in push_read (storable) of unknown impact.
372
3734.22 Sun Jul 20 16:34:13 CEST 2008
374 - new function AnyEvent::Socket::parse_hostport.
375 - as the bulkheads at microsoft can't even get getprotobyname reliably
376 working on their shitty fucking broken os we need to hardcode
377 some common protocol numbers in AnyEvent::Socket. How can
378 people even bother with such a pile of shit as windows.
379
3804.21 Thu Jul 17 14:40:05 CEST 2008
381 - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
382 which is incompatible to previous invocation syntax.
383 - work around more windows perl bugs in fork_call. I cannot imagine
384 why anybody would bother implementing fork in such an obviously
385 unusable way.
386 - avoid calling $do_retry if the request has already finished in
387 AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
388 K. Sharifulin).
389
3904.2 Sat Jul 12 22:42:11 CEST 2008
391 - support an "interval" argument for repeating timers.
392 - fix a bug in the pure perl event loop that caused timers to
393 be delayed under some circumstances.
394 - implement optional argument checking via PERL_ANYEVENT_STRICT.
395 - not importing anything from Event causes it to malfunction
396 and not use Time::HiRes, work around this bug.
397 - more bug workarounds against the endlessly broken Tk module,
398 seems to work now on 32 bit machines, but less so on 64 bit.
399 - minor optimisations applied to most backends.
400
4014.161 Fri Jul 4 14:24:48 CEST 2008
402 - fixed the t/handle/02_write.t, it read after write, with the
403 assumption that all data could be written before read
404 (reported by Jim Razmus).
