1 root 1.1 Revision history for Perl extension AnyEvent.
2    
3 root 1.191 4.3
4 root 1.193 - fixed a great number of bugs and corner cases in AnyEvent::Handle:
5     - fix a bug in where in SSL connect mode, the
6 root 1.191 client would first wait for some data by the server and
7     otherwise hang. (Reported and analyzed in an absolutely
8     exemplary manner by Adam Rosenstein).
9 root 1.193 - fix a bug in where SSL EOF would not be treated
10 root 1.191 as stream EOF, putting the connection into a hung state.
11     (Reported and analyzed in an absolutely exemplary manner by Adam
12     Rosenstein).
13 root 1.193 - fix a potential segfault when the TLS context
14 root 1.191 would go missing in a read callback (e.g. due to stoptls) -
15     Net::SSLeay of course makes no type checking whatsoever.
16 root 1.192 - AnyEvent::Handle will not stop the read watcher in TLS mode.
17     - AnyEvent::Handle->stoptls will send a TLS close notify
18     instead of simply destroying the stream now.
19 root 1.193 - on_drain will now take the tls write buffer into account.
20     - SSL operations have been streamlined a bit and should be faster
21     now, more to come, though.
22 root 1.191
23 root 1.190 4.234 Mon Sep 29 04:08:13 CEST 2008
24 root 1.189 - fix child watcher documentation: only child exits will be reported,
25     no trace events.
26 root 1.190 - mention SIGPIPE in AnyEvent::Handle.
27     - perl backend will now use POSIX::times as monotonic clock
28 root 1.188 when available and the monotonic clock option is not.
29 root 1.187 - run even without Time::HiRes in some cases now, but do not
30 root 1.190 provide sub-second accuracy (all *supported* perl versions have
31 root 1.187 Time::HiRes).
32    
33 root 1.186 4.233 Fri Aug 22 01:48:05 CEST 2008
34     - fix a bug in the testsuite, causing a hang.
35     - clarified lots of AnyEvent::Handle constructor arguments.
36    
37 root 1.185 4.232 Thu Aug 21 20:44:25 CEST 2008
38     - fix a bug in AnyEvent::Handle that could cause two fatal error
39     callbacks on EOF, which caused AnyEvent::HTTP to signal success twice
40     (testcase by Leon Brocard).
41     - clarified on_eof/on_error documentation a bit.
42    
43 root 1.184 4.231 Tue Jul 29 13:12:15 CEST 2008
44     - remove some debugging code left in AnyEvent::Util::fork_call
45     (and no, it's impossible to implement with the broken windows
46     perls without resource leaks or worse).
47    
48 root 1.183 4.23 Tue Jul 29 12:19:59 CEST 2008
49 root 1.177 - document the first parameter passed to condvar callbacks to be
50     the callback.
51 root 1.178 - add AnyEvent::Socket::{ntoa,aton} aliases.
52 root 1.180 - optimize the AE::Handle->push_read (line) for the default
53 root 1.179 eol marker.
54 root 1.180 - optimize push_read (packstring|storable) for small packets.
55 root 1.182 - invoke on_error callback when no on_eof callback is set.
56 root 1.180 - fix a bug in push_read (storable) of unknown impact.
57 root 1.177
58 root 1.176 4.22 Sun Jul 20 16:34:13 CEST 2008
59 root 1.174 - new function AnyEvent::Socket::parse_hostport.
60 root 1.175 - as the bulkheads at microsoft can't even get getprotobyname reliably
61     working on their shitty fucking broken os we need to hardcode
62     some common protocol numbers in AnyEvent::Socket. How can
63     people even bother with such a pile of shit as windows.
64 root 1.174
65 root 1.173 4.21 Thu Jul 17 14:40:05 CEST 2008
66 root 1.171 - INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype
67     which is incompatible to previous invocation syntax.
68 root 1.172 - work around more windows perl bugs in fork_call. I cannot imagine
69     why anybody would bother implementing fork in such an obviously
70     unusable way.
71     - avoid calling $do_retry if the request has already finished in
72     AnyEvent::DNS, thus avoiding an exception (reported by Anatoly
73     K. Sharifulin).
74 root 1.170
75 root 1.169 4.2 Sat Jul 12 22:42:11 CEST 2008
76 root 1.165 - support an "interval" argument for repeating timers.
77 root 1.164 - fix a bug in the pure perl event loop that caused timers to
78     be delayed under some circumstances.
79 root 1.167 - implement optional argument checking via PERL_ANYEVENT_STRICT.
80 root 1.169 - not importing anything from Event causes it to malfunction
81     and not use Time::HiRes, work around this bug.
82     - more bug workarounds against the endlessly broken Tk module,
83 root 1.168 seems to work now on 32 bit machines, but less so on 64 bit.
84 root 1.164 - minor optimisations applied to most backends.
85    
86 root 1.163 4.161 Fri Jul 4 14:24:48 CEST 2008
87 elmex 1.162 - fixed the t/handle/02_write.t, it read after write, with the
88 root 1.163 assumption that all data could be written before read
89     (reported by Jim Razmus).
90 elmex 1.162
91 root 1.161 4.160 Thu Jul 3 04:02:21 CEST 2008
92 root 1.160 - re-registering signal watchers after unregistering one did
93     not work if a backend falls back on AnyEvent's default
94     implementation (also affected child watchers).
95 root 1.159 - new AnyEvent::Handle options: autocork and no_delay.
96    
97 root 1.158 4.152 Sun Jun 22 14:15:44 CEST 2008
98 root 1.159 - allow for 32-bit perls that implement shifts differently
99     on different architectures in parse_ipv4 (reported and
100 root 1.158 analysed by Keiichi DAIBA).
101    
102 root 1.157 4.151 Fri Jun 6 17:34:24 CEST 2008
103     - make sure specifying _only_ on_read and never pushing reads
104     works.
105    
106 root 1.155 4.15 Fri Jun 6 13:00:46 CEST 2008
107 root 1.154 - the pure perl backend would keep some watchers alive when more than
108     one watcher was registered for the same fd.
109 root 1.155 - new "packstring" and "storable" read and write types
110     for AnyEvent::Handle.
111 root 1.156 - allow on_eof handler to be called after on_error with EPIPE returns.
112 root 1.153 - do not immediately call on_read callback in handle constructor.
113    
114 root 1.152 4.14 Thu Jun 5 20:29:31 CEST 2008
115 elmex 1.149 - Fixed a bug in DNS SRV priority sorting.
116 root 1.150 - AnyEvent::Util::guard now reports runtime errors while
117     executing the guard block as warnings.
118 root 1.152 - handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.
119 elmex 1.149
120 root 1.148 4.13 Thu Jun 5 00:47:59 CEST 2008
121 root 1.146 - AnyEvent::DNS only followed cname chains with length 2,
122     contrary to documentation. bumped it up to 10, thanks to
123     microsoft, the current broken-dns-config-king.
124 root 1.147 - AnyEvent::DNS didn't check for socket return status
125     but instead relied on perl not creating filehandles in that
126     case - too bad it gives you a bogus file handle (reported
127     and analysed by Vladimir Timofeev).
128 root 1.145 - fix queue management logic in AnyEvent::Handle:
129     when on_read was registered, the queue was empty
130     and no progress could be made AnyEvent::Handle would
131     enter an endless loop.
132     - correctly start reading again when the handle became
133     busy again after idling.
134 root 1.146 - correctly treat tls shut-downs as EOF condition
135     (for the time being, would be nice to have a callback for that).
136 root 1.145 - correctly call eof callback under all conditions
137     (hopefully).
138 root 1.146 - the timeout callback did not expect that $self can go
139     away any time.
140 root 1.145
141 root 1.144 4.12 Tue Jun 3 10:58:04 CEST 2008
142     - include AnyEvent::Intro, a tutorial for anyevent,
143     anyevent::socket and anyevent::handle.
144 root 1.143 - allow more options in on_error.
145 root 1.142
146 root 1.141 4.11 Fri May 30 23:42:25 CEST 2008
147 root 1.135 - INCOMPATIBLE CHANGE: replace ptr by real PTR lookup, provide
148     reverse_lookup and reverse_verify to replace it, support
149     v4mapped and v4compat addresses.
150 root 1.129 - provide more documentation for the resolver class.
151 root 1.130 - really replace longest run of :0: by :: in format_address,
152     also properly convert :: and ::1 again.
153 root 1.134 - support NAPTR record name and decode it.
154 root 1.133 - implement random weight sampling for SRV records, as per
155     rfc 2782.
156 root 1.137 - correctly abort on srv-record targets of ".".
157     - added AnyEvent::DNS::wait_for_slot.
158 root 1.138 - in the unlikely event of a virtual circuit connection
159     being invalidated by a delayed udp reply, AnyEvent::DNS
160     could die. this has been fixed.
161     - plug a probable memleak in the DNS vc code.
162     - use configured timeout also for VC request phase.
163 root 1.139 - implement timeout and max_outstanding methods
164     for resolver class.
165 root 1.140 - update version numbers in all modules.
166 root 1.129
167 root 1.128 4.1 Thu May 29 05:45:40 CEST 2008
168 root 1.123 - INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address
169     which mirrors their purpose better (old names still available
170     for a while). Also moved AnyEvent::DNS::addr to
171     AnyEvent::Socket::resolve_sockaddr.
172 root 1.127 - implement AnyEvent->time and AnyEvent->now.
173 root 1.124 - fix IPv6 support in pack_sockaddr.
174 root 1.123 - officially un-experimentalise all newly introduced code.
175     - support unix domain sockets everywhere by specifying
176     a host of "unix/" and the pathname as service.
177 root 1.126 - implement an activity timeout in AnyEvent::Handle.
178 root 1.122 - added a regex read type to AnyEvent::Handle.
179     - added a json read/write type to AnyEvent::Handle.
180 root 1.118 - always croak in on_error in AnyEvent::Handle.
181     - document how to subclass AnyEvent::Handle.
182 root 1.120 - implement AnyEvent::Util::fork_call.
183 root 1.127 - add support for IPv6 nameservers and nameserver statements.
184 root 1.121 - work around _yet_ _another_ windows perl bug in where empty
185     select masks cause errors in the pure perl backend (this
186     workaround cannot be implemented for the other event loops,
187     but EV also works around this).
188 root 1.123 - supply AnyEvent::Socket::address_type and make good use of it.
189 root 1.122 - clarify and fix the Handle documentation w.r.t $self vs. $handle
190     vs. callback arguments.
191 root 1.127 - add some recommends to the META.yml.
192 root 1.117
193 root 1.116 4.05 Mon May 26 19:44:06 CEST 2008
194     - some platforms ignore the rfc and prepend an extra sa_len member to
195     the sockaddr structure, cater for those. also use sockaddr_family,
196     didn't know it was there, but comes in handy for the workaround.
197 root 1.114 - undo the import WIN32 hack.
198    
199 root 1.113 4.04 Mon May 26 08:03:31 CEST 2008
200 root 1.109 - try to work around yet another windows bug: failed connects are reported
201 root 1.110 as if it were out-of-band data. windows users: you suck. Only
202     EV, Glib, Event and the pure perl backend can handle this condition.
203 root 1.111 - optimize write algorithm in AnyEvent::Handle.
204 root 1.106 - properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
205 root 1.112 - tcp_connect now properly iterates through all targets.
206 root 1.104 - check wether IPv6 sockets can actually be created, otherwise, disable ipv6
207 root 1.114 support entirely. also hardcode some AF_INET6 constants for the
208 root 1.107 sake of perl 5.8.
209 root 1.106 - vastly improved nameserver/suffix detection algorithm for windows
210     (still a hack...)
211     - try to use a fallback dns server if no dns servers could be found.
212 root 1.108 - splatter around some local $SIG{__DIE__}'s to work around bad
213     die handlers.
214 root 1.104
215 root 1.102 4.03 Sun May 25 05:05:57 CEST 2008
216 root 1.100 - work around perl bugs on windows, where perl returns undocumented
217     error codes for sysread, syswrite etc.
218 root 1.96 - fix AnyEvent::Handle::unshift_read to really unshift and not push.
219 root 1.97 - AnyEvent::Handle could sometimes stumble over 0-byte writes.
220 root 1.101 - fix unpack_sockaddr, now works for AF_INET6 sockaddr's.
221 root 1.100 - updated documentation.
222 root 1.103 - lots of workarounds for perl 5.8 quirks.
223 root 1.98 - implement a more flexible type system for both reads and writes
224     in AnyEvent::Handle.
225 root 1.101 - support IPv6 in tcp_server.
226     - pass local hostname and port to the prepare callback in tcp_server.
227 root 1.99 - make types extendable in AnyEvent::Handle.
228 root 1.100 - croak, not die, in AnyEvent::Handle;
229 root 1.96
230 root 1.95 4.0 Sat May 24 19:58:08 CEST 2008
231 root 1.88 - added (experimental) AnyEvent::DNS module.
232     - added (experimental) AnyEvent::Socket module.
233 root 1.93 - added (experiemntal) support for TLS/SSL in AnyEvent::Handle.
234 root 1.90 - make condvar->end call ->send as documented.
235     - make condvar constructor support the documented cb => argument.
236 root 1.94 - overload condvars so you can use them instead of code references.
237 root 1.93 - support more of the POSIX forms instead of a pure dotted quad for
238 root 1.89 verbatim ip addresses.
239 root 1.88 - AnyEvent::Socket::inet_aton will use AnyEvent::DNS now and not fork anymore.
240 root 1.87 - try very hard not to freeze on broken windows perls.
241 root 1.86 - make on_eof optional in AnyEvent::Handle.
242 root 1.83 - support service names in tcp_connect and tcp_server.
243 root 1.84 - work around netbsd/openbsd bug causing unix sockets not to
244 root 1.121 become writable until empty.
245 root 1.81 - only make a dummy read for error detection when getpeername
246     returns ENOTCONN.
247 root 1.181 - defend AnyEvent::Util::inet_aton against Coro::LWP's brutal
248 root 1.82 override.
249 root 1.91 - new AnyEvent::Guard::cancel.
250 root 1.81
251 root 1.80 3.5 Sat May 17 23:17:14 CEST 2008
252 root 1.79 - gracefully deal with systems not defining CLOCK_MONOTONIC
253     (as opposed to not supporting the clock itself, which worked in 3.41).
254 root 1.77 - added AnyEvent::Util::tcp_connect and AnyEvent::Util::tcp_server
255     helpers, to replace the ill-designed AnyEvent::Socket class.
256     - added some examples (eg/connect, eg/handle).
257     - added AnyEvent::Util::guard.
258     - AnyEvent::Util now exports most of its functions.
259 elmex 1.74 - fixed a bug in *_read_chunk, where the callback was called with $self as
260     first and second argument.
261 root 1.77 - simplified and fixed regex handling in AnyEvent::Handle::*_read_line.
262 root 1.72 - fix manpage condvars examples to use new syntax.
263 root 1.78 - considerably improve inet_aton with EV::ADNS backend to support
264     cname chains (common dns configuration bug, e.g. with www.google.de)
265     and aaaa records if no a record could be found.
266 root 1.72
267 root 1.71 3.41 Sun May 11 19:53:13 CEST 2008
268     - work around a bug in perl 5.8.8's local. Reported by Yi Ma Mao.
269    
270 root 1.70 3.4 Sun May 11 00:29:25 CEST 2008
271 root 1.181 - complete re-implementation of condvars with a hopefully much more useful
272 root 1.70 API (backward compatible functions exist but are undocumented).
273 root 1.69 - AnyEvent::Handle fully rewritten with a hopefully more powerful API
274     (still subject to change).
275 root 1.63 - take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl.
276 root 1.68 - provide AnyEvent::post_detect and @AnyEvent::post_detect, which
277 root 1.67 allows module authors to avoid forcing event loop detection.
278     (used by Coro::AIO, Coro::BDB, Coro::AnyEvent for example).
279 root 1.66 - remove coro backends: Coro now provides generic support for AnyEvent
280     via Coro::AnyEvent.
281 root 1.63
282 root 1.62 3.3 Mon Apr 28 09:51:06 CEST 2008
283     - added AnyEvent::Handle, AnyEvent::Socket and AnyEvent::Util modules.
284 root 1.55 - fix a bug in the pure perl backend that kept watchers alive
285     when multiple watchers were registered for the same fh/poll combo.
286 root 1.54 - add a benchmark section showing AnyEvent overhead and comparing
287     the different event loops with each other.
288 root 1.56 - prefer pure perl over tk when autoprobing, as it's about as fast,
289     but doesn't crash with many watchers.
290 root 1.62 - declare Qt support non-experimental.
291 root 1.56 - clarify the confusing section about the file descriptor being
292     kept alive.
293     - document the race between loading of an event module and
294     child processes exiting.
295 root 1.53 - support POE as "backend" (with some caveats, POE is not generic
296 root 1.54 enough, and darn slow).
297 root 1.53 - support Wx and Prima through POE.
298 root 1.60 - optimise perl backend to use 20% less memory and take advantage
299 root 1.62 of typical timeout behaviour. It can now compete with
300 root 1.60 select/poll-based C event loops in most cases (it is usually
301     faster than Event and Glib :).
302 root 1.59 - roughly cut EV memory use in half and increase its speed by 30%,
303 root 1.62 by removing undocumented functionality. Did something similar
304     to other event loops where possible.
305 root 1.53
306 root 1.50 3.2 Thu Apr 24 10:10:40 CEST 2008
307 root 1.51 - do not die when anyevent watchers are destroyed while running callbacks
308     in the pureperl backend (could only happen when two watchers are registered
309     for the same fh/poll combo).
310     - support autoloading for child watchers, was broken in all versions.
311 root 1.47 - implement PERL_ANYEVENT_MODEL env variable.
312 root 1.49 - (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
313     - (experimental) implement interface to the Qt module (cannot be autoprobed).
314 root 1.52 - this release is IO:AnyEvent-proof.
315 root 1.47
316 root 1.46 3.12 Tue Apr 22 07:11:46 CEST 2008
317     - reinstate AUTHOR section that got lost somehow.
318     - do not hang in the testsuite with badly broken perls (activestate,
319     strawberry...), but instead diagnose the problem and continue.
320     - use INT instead of CHLD in an attempt to support broken windows perls
321     better (this decreases the test quality, unfortunately).
322     - do not send the signal to the process group
323     (no problem for CHLD, bad for INT :).
324    
325 root 1.45 3.11 Sat Apr 19 06:57:31 CEST 2008
326     - major documentation rework.
327     - document the fact that child watchers only watch for zombies.
328     - fix the child watcher example.
329    
330 root 1.43 3.1 Wed Apr 16 17:09:01 CEST 2008
331 root 1.40 - work around recurring bugs in Tk by dup'ing filehandles, the
332 root 1.43 only method with good success chances on Tk (the bugs apparently
333     don't get fixed anytime soon).
334 root 1.42 - lift the restriction of only one watcher per fh direction
335     (as the Tk bug workaround also lifts it and only Tk imposed
336     such strong limits).
337 root 1.41 - changed probe order to prefer coro adaptors.
338     - explain why recursion into the event loop is not supported
339     unless the backend supports it (only Coro::EV does without
340     any restrictions...).
341     - add simple manpages for all backend modules.
342 root 1.40
343 root 1.39 3.0 Mon Apr 7 21:30:23 CEST 2008
344 root 1.38 - Coro::Signal changed semantics, roll our own, also cleaning
345     up the Coro implementation in general.
346     - rename Coro backend to CoroEvent.
347     - add some decision helping paragraph to the manpage that should
348 root 1.44 help people to decide whether AnyEvent is the right thing for them.
349 root 1.38
350 root 1.37 2.9 Mon Jan 28 13:31:54 CET 2008
351     - update for EV 3.0 API changes.
352    
353 root 1.36 2.8 Sun Nov 25 15:06:03 CET 2007
354     - waitpid can validly return 0. accept this fact of life
355     instead of reporting it to any watchers.
356    
357 root 1.35 2.7 Fri Nov 23 11:41:14 CET 2007
358 root 1.34 - force use of AnyEvent::Impl::Perl in testsuite, there is
359     too much breakage outside AnyEvent.
360 root 1.35 - deliver signals synchronously in AnyEvent::Impl::Perl
361     or any other event loop that relies on AnyEvents child
362     watcher emulation. *Could* help with hanging testsuite
363     (except when Event or EV are installed).
364 root 1.34
365 root 1.33 2.6 Fri Nov 9 20:36:35 CET 2007

393 root 1.19 - avoid $AUTOLOAD because many perls corrupt it.
394 root 1.20 - AnyEvent::detect forces autodetection.
395     - implement signal watchers (experimental)
396     (Tk does not support async signals (<= 804.027 at least),
397     so they might get delayed indefinitely on Tk).
398     - implement child watchers (experimental).
399     - moved default condvar implementation into base module, simplifying
400     most implementation modules.

409     - INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
410     - EXPERIMENTAL:
411     new pure-perl model added, AnyEvent now always finds a suitable
412     event model.

427 root 1.6 - fixed errors in the documentation.
428 root 1.7 - going back to using $VERSION as "load check",
429     as suggested by Jörn Reder. Let's see why I stopped using
430     this method.
431     - add 'hup' to the list of events to receive for glib
432     and generate 'rw' events for it, as some versions of
433     glib seem to require this, while this breaks other
434     (older) versions of glib.

444 root 1.44 - check whether a valid method was called, to avoid endless loops.
445 root 1.4 - move condvars into their own class (cleaner, safer).
446     - don't die when some modules are not available.
447     - Tk is too broken to allow for words. Will work once Tk works.
