3TODO: docs signal for condvar
4
5 - AF_INET6 was not properly used from Socket6 during configuration
6 time (found by Andy Grundman).
7
85.26 Mon Apr 12 04:49:35 CEST 2010
9 - don't generate spurious readyness notifications when select
10 returns EINTR in the pure perl backend (analysed and testcase
11 by Bas Denissen).
12 - give same examples in SYNOPSIS sections of AnyEvent and AE.
13 - provider faster implementations for AE::time/now/now_update for
14 EV and Perl backends.
15 - provide faster AE::cv and AE::time implementations for all
16 backends.
17 - no longer support lower/mixed-case signal names (this was
18 never documented nor universally supported).
19 - some more memory ยต-optimisations, and somewhat less messy
20 code to cope with both AnyEvent and AE APIs.
21
225.251 Sat Mar 13 00:58:21 CET 2010
23 - make test failed if it was run before make install on perl <=
24 5.8.8, and older versions of perl make our live very difficult,
25 so write constants.pl during Makefile.PL time.
26
275.25 Sat Mar 13 00:23:14 CET 2010
28 - fix a race condition in AnyEvent::Handle that would cause
29 a "bio_read: unsupported method" error (in _another_
30 ssl connection) after user code threw an exception.
31 - added AnyEvent::Handle->destroyed method.
32 - speed up AnyEvent::Socket::format_address and ::format_ipv6.
33 - the AnyEvent::Util::fh_nonblocking function worked only
34 by lucky accident on win32.
35 - smaller and faster AnyEvent::Util::fh_nonblocking.
36 - when the (required!) Time::HiRes module is missing, AnyEvent
37 did not fall back to built-in time properly.
38 - do not load Fcntl at runtime, saving memory and loading time.
39 - precompile a number of constants and use them instead of runtime
40 detection and eval.
41 - free detection code after detection and similar memory optimisations.
42 - Perl backend timer interval best effort drift has been improved
43 (same algorithm as EV).
44 - update unicode idna mapping table.
45
465.24 Tue Jan 5 11:39:43 CET 2010
47 - cygwin never reports errors from failed connects. 1.5 just gives
48 you continous readyness and EAGAIN, 1.7 is even more broken and
49 just hangs. work around both issues in a cygwin-specific hack.
50 - improve idle watcher documentation slightly.
51
525.23 Sun Dec 20 23:48:00 CET 2009
53 - support IDNs in resolve_sockaddr, and therefore in tcp_connect.
54 - implement punycode_encode/decode, idn_nameprep,
55 idn_to_ascii and idn_to_unicode operations in AnyEvent::Util.
56 - provide $AE::VERSION.
57 - removed traces of "no strict 'refs'".
58
595.22 Sat Dec 5 03:51:13 CET 2009
60 - downgrade-or-fail in AnyEvent::Handle::push_write, to
61 diagnose encoding failures earlier and more succinctly.
62 (this works around bugs in perl, throwing away encoding info
63 when passing scalar data to extensions).
64 - add more examples to AnyEvent::Socket manpage.
65 - upgrade internal warning set to the same as common::sense 2.03.
66 - use pack "n/a*" for pre-5.8.9 perl compatibility in AnyEvent::DNS
67 (John Beppu).
68 - AnyEvent::Socket::inet_aton now properly supports ipv6, as documented.
69 - add google public dns servers to fallback server set and make sure
70 we load-balance properly between the three sets. also add all
71 fallback dns servers, not just a random one, to each dns config.
72
735.21 Thu Nov 19 02:48:47 CET 2009
74 - fix a problem where socket constants were called with parameters
75 (spotted by David Friedland).
76 - fork_call never use'd POSIX (reported by Daisuke Maki).
77 - improve perl 5.6 compatibility further (but it still won't work
78 unless you rip out everything but the core).
79 - prefer Net::DNS::Resolver over ipconfig, if installed, on win32.
80 uses 10MB of RAM, but doesn't open a console window. *sigh*.
81
825.202 Wed Oct 14 22:35:44 CEST 2009
83 - AnyEvent::DNS would unexpectedly clobber $_ under windows
84 (analysed by Matthias Waldorf).
85 - AnyEvent::Handle::run_cmd can now pass the PID of the
86 newly-created process, which is much less useful than it might
87 sound (based on patch by Yann Kerherve).
88
895.201 Tue Sep 29 12:09:25 CEST 2009
90 - AnyEvent:Handle::on_starttls/on_stoptls methods were broken
91 (reported by Torsten Foertsch).
92 - common::sense 2.0 could cause tcp_server to throw an exception
93 (analysed by elmex).
94
955.2 Mon Sep 14 07:04:49 CEST 2009
96 - INCOMPATIBLE CHANGE: do no longer support register_read_type
97 and register_write_type in AnyEvent::Handle, instead support
98 package names (the facility was mostly abused).
99 - implement "packagename-as-read/write type" support in
100 AnyEvent::Handle.
101 - AnyEvent::Handle: new options "keepalive" and "oobinline".
102 - oobinline set by default to avoid security issues.
103 - the pure-perl event loop backend wrongly detected times() fallback
104 support (spotted by Pavel Boldin).
105
1065.12 Tue Sep 1 20:26:50 CEST 2009
107 - be more lenient when parsing resolv.conf files, as some people
108 use hashmarks as comment indicator inside directives (reported
109 by Michael S. Fischer).
110 - use same set of warnings as common::sense 2.0.
111 - fix a potential 32 bit overflow issue due to perl having problems
112 with large hex constants in the Perl backend.
113 - do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS
114 by default.
115 - fix some prototypes.
116 - (optionally) require Async::Interrupt 1.02.
117 - replace opendns fallbacks by verizon/level3 public dns servers.
118
1195.112 Fri Aug 21 13:59:04 CEST 2009
120 - AnyEvent::Handle could cause hard crashes in Net::SSLeay when
121 using starttls with an illegal/uncreatable tls context.
122 - port to broken win32 perls.
123
1245.111 Sun Aug 16 18:44:36 CEST 2009
125 - perl errornously requires sockaddr_un structures returned by the
126 kernel to have a specific length. work around this bug by padding
127 sockaddr_un structures (found to fail on OS X, as perl only uses
128 the correct code for GNU/Linux, but likely to fail on other
129 OSes as well).
130
1315.11 Wed Aug 12 17:49:37 CEST 2009
132 - fixed a bug in run_cmd with input from filename.
133 - create a json coder object when none is given in write direction
134 to reduce dependency on JSON.
135
1365.1 Tue Aug 11 03:17:32 CEST 2009
137 - tcp_connect now reports the correct error in $!, not an unrelated
138 one (was broken since 4.91).
139 - AE::Handle did not properly clear rtimeout/wtimeout watchers
140 when retrying a tcp_connect.
141 - new functions: AnyEvent::Util::run_cmd and close_all_fds_except.
142 - fixed wrong documentation in AE::Socket.
143
1445.01 Mon Aug 10 03:16:32 CEST 2009
145 - last release broke EV child watchers :/.
146
1475.0 Sun Aug 9 17:32:09 CEST 2009
148 - officially introduce and document the AE API.
149 - lowering the timeout at runtime did not have immediate effect
150 in AnyEvent::Handle.
151 - AE::Handle now has separate and independent read and write timeout
152 settings.
153 - probe for Guard module when AnyEvent::Util is loaded, not at
154 runtime (Event doesn't like eval "use" from callbacks, and it avoids
155 exporting the probe function).
156 - Impl::IOAsync's io watchers did not use the filehandle emulation
157 code to work around it's watcher limits.
158 - work around IO::Async's problems with overloaded objects.
159 - try to disable wearnings inside IO::Async, it's just too buggy.
160 - do no longer use Event by default, only EV or Perl, Event is too buggy.
161 - hackishly provide fast AE:: interface when EV or Perl is the backend.
162 - inherit VERSION from AnyEvent::VERSION in most modules.
163
1644.91 Thu Aug 6 15:42:45 CEST 2009
165 - AE::Handle::starttls could get out of sync when the read buffer
166 already contains some TLS handshake.
167 - AE::Handle did not properly free the TLS session, causing bigger
168 memory leaks in Net::SSLeay than expected (reported by toaster).
169 - AE::Socket::tcp_connect will now artificially delay invoking
170 the callback to avoid returning after invoking the callback.
171 - convert many internal watcher uses to AE API.
172
1734.9 Sat Aug 1 11:07:01 CEST 2009
174 - Glib silently fails when registering a timeout with
175 a negative value, so avoid that.
176 - call condvar callback immediately when it is set
177 after the condition is already signalled.
178 - check rbuf_max condition only after trying to consume
179 data.
180 - normalise signal numbers to names when using the ae's
181 signal handling, but do not document this (yet).
182 - pure perl signal emulation did not properly set nonblocking
183 mode on the signal pipe on win32 (this is unlikely to have caused
184 any issues).
185 - new module: AnyEvent::Debug.
186 - AnyEvent::Strict now checks that a signal was specified
187 by name (not name or number).
188 - reduce memory footprint in typical cases by ~50kb by
189 only compiling signal code when necessary.
190 - add AnyEvent::Handle->rbuf_max.
191 - grab the AE namespace for future new API, implement stubs for
192 said future/alternative API.
193 - new function: AnyEvent::Socket::format_hostport.
194
1954.881 Tue Jul 28 12:51:53 CEST 2009
196 - work around a bug in local in pre-5.10 perls, causing
197 AnyEvent::Handle to recurse when it should not
198 (analysed by elmex).
199
2004.88 Tue Jul 28 04:04:37 CEST 2009
201 - re-bless the handle into a dummy package after calling
202 AnyEvent::Handle::destroy, so the user does not need to check
203 for errors after every push_write etc.
204 - do not attempt to run t/02_signals.t on obviously broken
205 platforms.
206
2074.87 Sun Jul 26 02:06:16 CEST 2009
208 - do not attempt to linger when there is no longer a valid fh.
209 - enforce tls mode to be either accept or connect, do not simply
210 segfault in Net::SSLeay.
211 - AnyEvent::Handle can now call tcp_connect itself (new parameters
212 connect, on_prepare, on_connect and on_connect_error). Updated
213 tutorial accordingly.
214 - add AnyEvent::Impl::Irssi backend.
215
2164.86 Mon Jul 20 23:52:29 CEST 2009
217 - since the verbose warning is not enough, explicitly document
218 that versions before 1.33 of Net::SSLeay are not secure.
219 - work around signal handling races in Event and (...) Event::Lib.
220 - try to align signal-race timer to full-second boundaries.
221 - work around Tk not liking negative timeouts.
222 - don't complain of different grades of environmental unfriendlyness
223 in IO::Async.
224
2254.85 Sat Jul 18 06:16:14 CEST 2009
226 - nail the signal race problem in perl once and for all
227 (see $AnyEvent::MAX_SIGNAL_LATENCY).
228 - take advantage of Async::Interrupt if it is available.
229 - load Time::HiRes and Guard modules on demand only.
230 - add optional/recommended modules section to AnyEvent
231 documentation.
232 - reduce memory usage considerably (and reduce startup penalty)
233 by not using "strict", "warnings" and "overload" modules.
234 - work around buggy windows/openbsd perls and provide EBADMSG
235 and EPROTO ourselves when missing.
236 - improve perl 5.6 compatibility of the core event loop.
237 - made Net::SSLeay version 1.33 a soft requirement.
238
2394.83 Fri Jul 17 16:56:26 CEST 2009
240 - implement AnyEvent::Socket::getprotobyname.
241 - AnyEvent::CondVar's will now detect recursive blocking
242 waits and will croak, as too many people fall into
243 this trap.
244 - AnyEvent::Handle will now call ->destroy on itself after
245 executing the on_error callback, instead of doing some
246 half-baked internal shutdown, for fatal errors.
247 - clarify on_eof behaviour w.r.t. the read queue and
248 on_read callbacks.
249 - ignore some possible spurious wake-ups in tcp_connect.
250
2514.82 Sat Jul 11 00:34:55 CEST 2009
252 - POE and Event backends didn't accept some callable objects as
253 callbacks.
254 - use Config module instead of POSIX module to detect signal names
255 in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX
256 module doesn't even have all POSIX signals :/.
257 - use more workarounds around the many refcnt/corruption bugs in
258 Event::Lib.
259 - work around a race condition in perl's select, causing t/03_child.t
260 to rarely fail.
261
2624.81 Thu Jul 9 10:30:30 CEST 2009
263 - AnyEvent::Handle didn't properly diagnose write errors
264 (it expected -1 from syswrite, how lame... :).
265 - support file descriptors in addition to file handles
266 in AnyEvent->io.
267 - new env variables: PERL_ANYEVENT_RESOLV_CONF,
268 PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
269 and PERL_ANYEVENT_CA_PATH.
270 - provide a sensible synopsis section for AnyEvent::TLS.
271 - add a "supported backends" section to the manpage.
272 - added simple io watcher test to testsuite, using a
273 portable_socketpair.
274 - tried to improve the stability of the Event::Lib backend,
275 YMMV.
276
2774.8 Mon Jul 6 23:45:16 CEST 2009
278 - AnyEvent::DNS did not properly follow CNAME records with
279 uppercase targets.
280 - AnyEvent::DNS would errornously return AAAA records
281 with v4 mapped addresses (a faulty record) as ipv4 addresses,
282 causing AnyEvent::Socket to throw an exception.
283 - added new module AnyEvent::TLS for easier SSL/TLS context
284 creation, with many options including hostname verification,
285 secure default configuration, lots of documentation and,
286 predefined diffie-hellman keys for perfect forward security
287 and much more. get it while it's still fresh!
288 - use AnyEvent::TLS in AnyEvent::Handle for context management.
289 - load AnyEvent::Handle only on demand in AnyEvent::DNS,
290 so AnyEvent::Socket users have smaller memory footprint
291 in the common case.
292 - add AnyEvent::Handle->push_shutdown method.
293 - add an additional error message parameter to AnyEvent::Handle's
294 on_error callback (for TLS, $! is still available).
295 - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
296 - make AnyEvent::Handle more robust against early conenction
297 failures (during new), and return C<undef> in that case
298 from the constructor.
299 - AnyEvent::Handle will now try to load only JSON::XS first,
300 then fall back to JSON.
301 - format_ipv4/format_ipv6 are now exported by default, for symmetry,
302 and because it was documented that way.
303
3044.451 Fri Jul 3 00:28:58 CEST 2009
305 - do not clear rbuf when shutting down an AnyEvent::Handle
306 object - doing so breaks AnyEvent::HTTP.
307
3084.45 Mon Jun 29 22:59:26 CEST 2009
309 - a write error could cause AnyEvent::Handle to create
310 an I/O watcher with an undefined $fh.
311 - special-case mapped ipv4 addresses in both
312 AnyEvent::Socket::format_address and parse_address,
313 to treat them just like ipv4 addresses.
314 - updated and overhauled the AnyEvent::Intro doc.
315 - implement AnyEvent::Socket::format_ipv4/ipv6.
316 - slightly speed up portable_pipe/socketpair.
317 - expand condvar begin/end documentation.
318
3194.42 Fri Jun 26 08:32:18 CEST 2009
320 - preliminary and neccesarily incomplete support for IO::Async.
321 - reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
322 case it was set to IGNORE, to ensure we can catch child statuses
323 even when the calling env acts stupidly.
324 - updated benchmarks with IO::Async, which performs very well.
325
3264.412 Wed Jun 24 01:35:57 CEST 2009
327 - support an "untaint" attribute for AnyEvent::DNS
328 and set it on the default resolver.
329 - implement and document AnyEvent::Impl::Perl::loop.
330 - remove all anyevent-env variables from %ENV
331 when running in tainted mode.
332 - mention and extend the IO::Lambda benchmark.
333
3344.411 Sun Jun 7 18:48:02 CEST 2009
335 - do not try to use F_SETFD on windows.
336
3374.41 Thu May 14 06:40:11 CEST 2009
338 - work around issues in older perls (5.8.0?) when
339 a signal handler is deleted from the %SIG hash.
340 - use POSIX::_exit in child test, to avoid running
341 destructors.
342 - speed up CHLD handling by relying on SIGCHLD being
343 synchronously delivered, even when we roll our own
344 implementation.
345 - AnyEvent::DNS: add the "dname" resource record name
346 for cosmetic reasons.
347
3484.4 Sun Apr 26 20:12:33 CEST 2009
349 - implemented idle watchers, where applicable.
350 - AnyEvent->time died when Event backend was in use.
351 - fix a memleak in the Tk backend.
352 - sped up Tk timer handling.
353 - clip negative "after" values to 0 in AnyEvent::Impl::Event
354 to avoid spamming out warning messages.
355 - fix Qt timers without interval.
356 - avoid Qt zero-timeout special case, in old libqt's.
357
3584.352 Mon Apr 20 16:31:11 CEST 2009
359 - fix AnyEvent::Strict error messages for child watchers.
360 - fix/update Makefile.PL "recommends" versions.
361 - add AnyEvent->now_update.
362
3634.351 Sat Apr 11 07:56:14 CEST 2009
364 - actually make the signal pipe work under win32.
365 - localise $! in signal handler to avoid changing $!, although
366 perl itself does not seem to save/restore errno either.
367 - set the cloexec flag on the signal pipe (normally set by perl too).
368
3694.35 Fri Mar 27 11:48:20 CET 2009
370 - event models relying on AnyEvent's signal watcher emulation did
371 invoke the callback asynchronously, contradicting documentation
372 and causing signals to get lost (this includes AnyEvent's own
373 event loop). AnyEvent now uses the standard pipe trick to make
374 callback execution synchronous to the event loop.
375 - AnyEvent::Handle didn't free TLS context data on DESTROY
376 (patch by Pavel Shaydo).
377 - work around the ever-incompatibly-changing API of MakeMaker.
378 - document that changing global variables without restoring them
379 is a bad idea in Perl (noted by Adam Rosenstein).
380 - AnyEvent::Strict now barfs if ->io is passed a file.
2 381
34.34 Thu Feb 12 18:32:45 CET 2009 3824.34 Thu Feb 12 18:32:45 CET 2009
4 - separately buffer TLS read data, as otherwise the read queue could 383 - separately buffer TLS read data, as otherwise the read queue could
5 deadlock as receiving data is not expected while draining the 384 deadlock as receiving data is not expected while draining the
6 read queue (which cna only happen with TLS). 385 read queue (which cna only happen with TLS).
464.3 Fri Oct 3 09:18:43 CEST 2008 4254.3 Fri Oct 3 09:18:43 CEST 2008
