3TODO: maybe support "peerip" verificstion, i.e. getpeername diretcly as
4additional peername?
5
6 - do not attempt to linger when there is no longer a valid fh.
7 - enforce tls mode to be either accept or connect, do not simply
8 segfault in Net::SSLeay.
9 - AnyEvent::Handle can now call tcp_connect itself (new parameters
10 connect, on_prepare, on_connect and on_connect_error). Updated
11 tutorial accordingly.
12 - add AnyEvent::Impl::Irssi backend.
13
144.86 Mon Jul 20 23:52:29 CEST 2009
15 - since the verbose warning is not enough, explicitly document
16 that versions before 1.33 of Net::SSLeay are not secure.
17 - work around signal handling races in Event and (...) Event::Lib.
18 - try to align signal-race timer to full-second boundaries.
19 - work around Tk not liking negative timeouts.
20 - don't complain of different grades of environmental unfriendlyness
21 in IO::ASync.
22
234.85 Sat Jul 18 06:16:14 CEST 2009
24 - nail the signal race problem in perl once and for all
25 (see $AnyEvent::MAX_SIGNAL_LATENCY).
26 - take advantage of Async::Interrupt if it is available.
27 - load Time::HiRes and Guard modules on demand only.
28 - add optional/recommended modules section to AnyEvent
29 documentation.
30 - reduce memory usage considerably (and reduce startup penalty)
31 by not using "strict", "warnings" and "overload" modules.
32 - work around buggy windows/openbsd perls and provide EBADMSG
33 and EPROTO ourselves when missing.
34 - improve perl 5.6 compatibility of the core event loop.
35 - made Net::SSLeay version 1.33 a soft requirement.
36
374.83 Fri Jul 17 16:56:26 CEST 2009
38 - implement AnyEvent::Socket::getprotobyname.
39 - AnyEvent::CondVar's will now detect recursive blocking
40 waits and will croak, as too many people fall into
41 this trap.
42 - AnyEvent::Handle will now call ->destroy on itself after
43 executing the on_error callback, instead of doing some
44 half-baked internal shutdown, for fatal errors.
45 - clarify on_eof behaviour w.r.t. the read queue and
46 on_read callbacks.
47 - ignore some possible spurious wake-ups in tcp_connect.
48
494.82 Sat Jul 11 00:34:55 CEST 2009
50 - POE and Event backends didn't accept some callable objects as
51 callbacks.
52 - use Config module instead of POSIX module to detect signal names
53 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
54 module doesn't even have all POSIX signals :/.
55 - use more workarounds around the many refcnt/corruption bugs in
56 Event::Lib.
57 - work around a race condition in perl's select, causing t/03_child.t
58 to rarely fail.
59
604.81 Thu Jul 9 10:30:30 CEST 2009
61 - AnyEvent::Handle didn't properly diagnose write errors
62 (it expected -1 from syswrite, how lame... :).
63 - support file descriptors in addition to file handles
64 in AnyEvent->io.
65 - new env variables: PERL_ANYEVENT_RESOLV_CONF,
66 PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
67 and PERL_ANYEVENT_CA_PATH.
68 - provide a sensible synopsis section for AnyEvent::TLS.
69 - add a "supported backends" section to the manpage.
70 - added simple io watcher test to testsuite, using a
71 portable_socketpair.
72 - tried to improve the stability of the Event::Lib backend,
73 YMMV.
74
754.8 Mon Jul 6 23:45:16 CEST 2009
76 - AnyEvent::DNS did not properly follow CNAME records with
77 uppercase targets.
78 - AnyEvent::DNS would errornously return AAAA records
79 with v4 mapped addresses (a faulty record) as ipv4 addresses,
80 causing AnyEvent::Socket to throw an exception.
81 - added new module AnyEvent::TLS for easier SSL/TLS context
82 creation, with many options including hostname verification,
83 secure default configuration, lots of documentation and,
84 predefined diffie-hellman keys for perfect forward security
85 and much more. get it while it's still fresh!
86 - use AnyEvent::TLS in AnyEvent::Handle for context management.
87 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
88 so AnyEvent::Socket users have smaller memory footprint
89 in the common case.
90 - add AnyEvent::Handle->push_shutdown method.
91 - add an additional error message parameter to AnyEvent::Handle's
92 on_error callback (for TLS, $! is still available).
93 - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
94 - make AnyEvent::Handle more robust against early conenction
95 failures (during new), and return C<undef> in that case
96 from the constructor.
97 - AnyEvent::Handle will now try to load only JSON::XS first,
98 then fall back to JSON.
99 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
100 and because it was documented that way.
101
1024.451 Fri Jul 3 00:28:58 CEST 2009
103 - do not clear rbuf when shutting down an AnyEvent::Handle
104 object - doing so breaks AnyEvent::HTTP.
105
1064.45 Mon Jun 29 22:59:26 CEST 2009
107 - a write error could cause AnyEvent::Handle to create
108 an I/O watcher with an undefined $fh.
109 - special-case mapped ipv4 addresses in both
110 AnyEvent::Socket::format_address and parse_address,
111 to treat them just like ipv4 addresses.
112 - updated and overhauled the AnyEvent::Intro doc.
113 - implement AnyEvent::Socket::format_ipv4/ipv6.
114 - slightly speed up portable_pipe/socketpair.
115 - expand condvar begin/end documentation.
116
1174.42 Fri Jun 26 08:32:18 CEST 2009
118 - preliminary and neccesarily incomplete support for IO::Async.
119 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
120 case it was set to IGNORE, to ensure we can catch child statuses
121 even when the calling env acts stupidly.
122 - updated benchmarks with IO::Async, which performs very well.
123
1244.412 Wed Jun 24 01:35:57 CEST 2009
125 - support an "untaint" attribute for AnyEvent::DNS
126 and set it on the default resolver.
127 - implement and document AnyEvent::Impl::Perl::loop.
128 - remove all anyevent-env variables from %ENV
129 when running in tainted mode.
130 - mention and extend the IO::Lambda benchmark.
131
1324.411 Sun Jun 7 18:48:02 CEST 2009
133 - do not try to use F_SETFD on windows.
134
1354.41 Thu May 14 06:40:11 CEST 2009
136 - work around issues in older perls (5.8.0?) when
137 a signal handler is deleted from the %SIG hash.
138 - use POSIX::_exit in child test, to avoid running
139 destructors.
140 - speed up CHLD handling by relying on SIGCHLD being
141 synchronously delivered, even when we roll our own
142 implementation.
143 - AnyEvent::DNS: add the "dname" resource record name
144 for cosmetic reasons.
145
1464.4 Sun Apr 26 20:12:33 CEST 2009
147 - implemented idle watchers, where applicable.
148 - AnyEvent->time died when Event backend was in use.
149 - fix a memleak in the Tk backend.
150 - sped up Tk timer handling.
151 - clip negative "after" values to 0 in AnyEvent::Impl::Event
152 to avoid spamming out warning messages.
153 - fix Qt timers without interval.
154 - avoid Qt zero-timeout special case, in old libqt's.
155
1564.352 Mon Apr 20 16:31:11 CEST 2009
157 - fix AnyEvent::Strict error messages for child watchers.
158 - fix/update Makefile.PL "recommends" versions.
159 - add AnyEvent->now_update.
160
1614.351 Sat Apr 11 07:56:14 CEST 2009
162 - actually make the signal pipe work under win32.
163 - localise $! in signal handler to avoid changing $!, although
164 perl itself does not seem to save/restore errno either.
165 - set the cloexec flag on the signal pipe (normally set by perl too).
166
1674.35 Fri Mar 27 11:48:20 CET 2009
168 - event models relying on AnyEvent's signal watcher emulation did
169 invoke the callback asynchronously, contradicting documentation
170 and causing signals to get lost (this includes AnyEvent's own
171 event loop). AnyEvent now uses the standard pipe trick to make
172 callback execution synchronous to the event loop.
173 - AnyEvent::Handle didn't free TLS context data on DESTROY
174 (patch by Pavel Shaydo).
175 - work around the ever-incompatibly-changing API of MakeMaker.
176 - document that changing global variables without restoring them
177 is a bad idea in Perl (noted by Adam Rosenstein).
178 - AnyEvent::Strict now barfs if ->io is passed a file.
179
1804.34 Thu Feb 12 18:32:45 CET 2009
181 - separately buffer TLS read data, as otherwise the read queue could
182 deadlock as receiving data is not expected while draining the
183 read queue (which cna only happen with TLS).
184 - raise EBADMSG error on JSON decoding errors.
185 - fix some minor manpage bugs (reported by Maximilian Gaß).
186 - speed up select bitmask parsing quite a bit in the pure perl
187 backend.
188 - use CORE::select instead of just select in AnyEvent::Impl::Perl.
189
1904.331 Tue Jan 6 21:07:25 CET 2009
191 - socketpair fails on many vista machines because vista has
192 completely broken accept/getpeername and getsockname functions,
193 so we provide our own socketpair emulation that kind of works
194 (AnyEvent::Util::portable_pipe).
195 - new function: AnyEvent::Util::portable_socketpair.
196 - take advantage of the Guard module if it exists.
197
1984.33 Fri Nov 21 02:35:40 CET 2008
199 - AnyEvent::Strict did errornously flag a fileno of 0 as
200 illegal.
201 - reduce memory usage and slightly speed up the pure perl backend
202 by only storing the file descriptor, not the file handle.
203 - add missing autocork method to AnyEvent::Handle (reported
204 by Adam Rosenstein).
205 - AnyEvent::DNS->resolve errornously documented an $rcode result
206 argument, but there isn't (spotted by Henrik Krohns).
207 - the naked truth about Tk - it's basically unmaintained.
208
2094.32 Mon Nov 3 22:46:32 CET 2008
210 - fix AnyEvent::Socket::resolve_sockaddr to properly support
211 unix sockets again and choose a proper default for
212 the socket type.
213 - fix call to resolve_sockaddr in tcp_connect.
214
2154.31 Thu Oct 30 04:41:48 CET 2008
216 - implemented AnyEvent::Handle->destroy method.
217 - hint about unexpected effects in TLS mode.
218 - speed up AnyEvent::Impl::Perl by using more arrays
219 instead of hashes without the slightest loss of readability :)
220 - work around a perl argument refcounting bug.
221 - with some perl patches applied, AnyEvent now seems leak-free.
222
2234.3 Fri Oct 3 09:18:43 CEST 2008
224 - AnyEvent will now install a no-op signal handler for SIGPIPE,
225 unless one has been installed already.
226 - warn about not loaidng AnyEvent::Impl::POE early enough
227 (patch by Adam Rosenstein).
228 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
229 - fix a bug in where in SSL connect mode, the
230 client would first wait for some data by the server and
231 otherwise hang. (reported and analyzed in an absolutely
232 exemplary manner by Adam Rosenstein).
233 - fix a bug in where SSL EOF would not be treated
234 as stream EOF, putting the connection into a hung state.
235 (reported and analyzed in an absolutely exemplary manner by Adam
236 Rosenstein).
237 - fix a potential segfault when the TLS context
238 would go missing in a read callback (e.g. due to stoptls) -
239 Net::SSLeay of course makes no type checking whatsoever.
240 - AnyEvent::Handle will not stop the read watcher in TLS mode.
241 - AnyEvent::Handle->stoptls will send a TLS close notify
242 instead of simply destroying the stream now.
243 - fix a bug where large blocks of data written in TLS mode
244 would not be sent unless triggered by receives.
245 - on_drain will now take the tls write buffer into account.
246 - SSL operations have been streamlined a bit and should be faster
247 now, more to come, though.
248 - added a FAQ section, will document nontrivial issues in there.
249
2504.234 Mon Sep 29 04:08:13 CEST 2008
251 - fix child watcher documentation: only child exits will be reported,
252 no trace events.
253 - mention SIGPIPE in AnyEvent::Handle.
254 - perl backend will now use POSIX::times as monotonic clock
255 when available and the monotonic clock option is not.
256 - run even without Time::HiRes in some cases now, but do not
257 provide sub-second accuracy (all *supported* perl versions have
258 Time::HiRes).
259
2604.233 Fri Aug 22 01:48:05 CEST 2008
261 - fix a bug in the testsuite, causing a hang.
262 - clarified lots of AnyEvent::Handle constructor arguments.
263
2644.232 Thu Aug 21 20:44:25 CEST 2008
265 - fix a bug in AnyEvent::Handle that could cause two fatal error
266 callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
267 (testcase by Leon Brocard).
268 - clarified on_eof/on_error documentation a bit.
269
2704.231 Tue Jul 29 13:12:15 CEST 2008
271 - remove some debugging code left in AnyEvent::Util::fork_call
272 (and no, it's impossible to implement with the broken windows
273 perls without resource leaks or worse).
274
2754.23 Tue Jul 29 12:19:59 CEST 2008
276 - document the first parameter passed to condvar callbacks to be
277 the callback.
278 - add AnyEvent::Socket::{ntoa,aton} aliases.
279 - optimize the AE::Handle->push_read (line) for the default
280 eol marker.
281 - optimize push_read (packstring|storable) for small packets.
282 - invoke on_error callback when no on_eof callback is set.
283 - fix a bug in push_read (storable) of unknown impact.
284
2854.22 Sun Jul 20 16:34:13 CEST 2008
286 - new function AnyEvent::Socket::parse_hostport.
287 - as the bulkheads at microsoft can't even get getprotobyname reliably
288 working on their shitty fucking broken os we need to hardcode
289 some common protocol numbers in AnyEvent::Socket. How can
290 people even bother with such a pile of shit as windows.
291
2924.21 Thu Jul 17 14:40:05 CEST 2008
293 - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
294 which is incompatible to previous invocation syntax.
295 - work around more windows perl bugs in fork_call. I cannot imagine
296 why anybody would bother implementing fork in such an obviously
297 unusable way.
298 - avoid calling $do_retry if the request has already finished in
299 AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
300 K. Sharifulin).
301
3024.2 Sat Jul 12 22:42:11 CEST 2008
303 - support an "interval" argument for repeating timers.
304 - fix a bug in the pure perl event loop that caused timers to
305 be delayed under some circumstances.
306 - implement optional argument checking via PERL_ANYEVENT_STRICT.
307 - not importing anything from Event causes it to malfunction
308 and not use Time::HiRes, work around this bug.
309 - more bug workarounds against the endlessly broken Tk module,
310 seems to work now on 32 bit machines, but less so on 64 bit.
311 - minor optimisations applied to most backends.
312
3134.161 Fri Jul 4 14:24:48 CEST 2008
314 - fixed the t/handle/02_write.t, it read after write, with the
315 assumption that all data could be written before read
316 (reported by Jim Razmus).
317
3184.160 Thu Jul 3 04:02:21 CEST 2008
319 - re-registering signal watchers after unregistering one did
320 not work if a backend falls back on AnyEvent's default
321 implementation (also affected child watchers).
322 - new AnyEvent::Handle options: autocork and no_delay.
323
3244.152 Sun Jun 22 14:15:44 CEST 2008
325 - allow for 32-bit perls that implement shifts differently
326 on different architectures in parse_ipv4 (reported and
327 analysed by Keiichi DAIBA).
328
3294.151 Fri Jun 6 17:34:24 CEST 2008
330 - make sure specifying _only_ on_read and never pushing reads
331 works.
332
3334.15 Fri Jun 6 13:00:46 CEST 2008
334 - the pure perl backend would keep some watchers alive when more than
335 one watcher was registered for the same fd.
336 - new "packstring" and "storable" read and write types
337 for AnyEvent::Handle.
338 - allow on_eof handler to be called after on_error with EPIPE returns.
339 - do not immediately call on_read callback in handle constructor.
340
3414.14 Thu Jun 5 20:29:31 CEST 2008
342 - Fixed a bug in DNS SRV priority sorting.
343 - AnyEvent::Util::guard now reports runtime errors while
344 executing the guard block as warnings.
345 - handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.
346
3474.13 Thu Jun 5 00:47:59 CEST 2008
3 - AnyEvent::DNS only followed cname chains with length 2, 348 - AnyEvent::DNS only followed cname chains with length 2,
