5.34 Thu May 12 09:59:41 CEST 2011

• AE::TLS didn't support both cert_file and key at the same time, due to some copy&paste bug (reported and analyzed by vti).
• improve AE::Handle timeout documentation slightly.

5.33 Mon Feb 7 21:51:41 CET 2011

• never appeared on CPAN, for unknown reasons.
• AnyEvent::Handle on_connect_error - do not try to destroy a handle object when it's already gone (analyzed by Ryan Bullock).
• update idna algorithm(s) to UTS#46 version 6.0.0.
• preserve trailing dot in idn_to_ascii - testsuite says to preserve, uts46 says it's an error, and testsuite makes more sense.
• remove leading dots in idn_to_ascii - testsuite says to remove, uts46 says it's an error, and testsuite makes more sense.
• fixed a bug in idn ignored character processing.
• passes the uts46 6.0.0 testsuite except for three cases which apparently are bugs in the testsuite itself.
• passes the uts46 6.0.1 testsuite except for eleven cases which apparently are bugs in the testsuite itself.

5.31 Sun Jan 23 11:49:19 CET 2011

• work around a POE bug where POE would first poll for new events and invoke handlers BEFORE handling the message queue.
• fix parsing of "domain" statement in resolv.conf (Johannes Plunien).
• stop_read now does just that in TLS mode. see its documentation for caveats.
• update to common::sense 3.4 warning set (some warnings in perl impose an arbitrary 32kb limit on regex matches, which affects AnyEvent::Handle).
• AE::Handle had a broken rbuf_max method and missing wbuf_max method.
• new experimental AE::Handle::resettls method.

5.3 Fri Dec 31 05:48:13 CET 2010

• major IOAsync patch by Paul Evans - 0.33 is required, as the major issues with IO::Async have been solved in that version, including the availabilty of a default loop!
• implement new wbuf_max parameter for AnyEvent::Handle.
• added Cocoa::EventLoop backend by Daisuke Murase.
• the default testsuite now honors PERL_ANYEVENT_MODEL (Paul Evans).
• clarify handle on_prepare documentation.
• set CLOEXEC flag on parent-side fd's in AnyEvent::Util::run_cmd, to avoid leaking them to any child processes.
• try to force files into the arch-dependend lib directory, for the half-"turly obsessive compulsive person"(s) that depend on it.

5.29 Sun Dec 5 10:49:21 CET 2010

• convert EV backend to EV 4.00 API (so better upgrade EV too).
• AE::Handle: implement dynamic read_size adjustment, add max_read_size parameter, reduce default read_size to 2048.
• add some FAQ entries for servers and/or on_eof vs. on_error.
• work around OS bugs (cygwin again) when lingering in AE::Handle.
• reduce memory usage slightly when connect was used in AE::Handle.
• wrok around more segfaults in Tk.
• document tls_ctx => undef as valid.
• detect WNOHANG value at compiletime.
• include some probably linux-only support for building AnyEvent as part of the perl core.
• improve compatibility of t/08_idna.t to perl 5.8.
• make AnyEvent::Strict truly optional (in case somebody builds a minimal perl...).

5.28 Wed Oct 13 04:14:23 CEST 2010

• due to a glitch, AnyEvent's internal getprotobyname wasn't actually used in tcp_server.
• implement AnyEvent::CondVar->new method, which was documented but missing.
• support autoloading of read types in unshift_read.
• AnyEvent::Strict: do the test for invalid fh arguments differently, resulting in more informative error messages.
• new AnyEvent::FAQ manpage.
• clarify that you can actually call push_read etc. in on_read.
• put keys and certs in /tmp, not into the current directory, and document this in the SECURITY CONSIDERATIONS sections of AnyEvent::TLS.
• support ";" as resolv.conf comment character in AnyEvent::DNS, as requested by Ron Isaacson.
• document $AnyEvent::DNS::RESOLVER variable.
• incorporated major typo patches by Abhijit Menon-Sen.
• AnyEvent::Handle now croaks when negative timeouts are passed.
• add a shitload of TCP_xxx sockopt name constants to AnyEvent::Util, undocumented, but who knows when they might come in handy.

5.271 Tue Jun 8 12:05:46 CEST 2010

• backport to perl 5.8.x.

5.27 Sun Jun 6 12:12:05 CEST 2010

• postpone differently in AnyEvent::Socket now, as when not, canceling the connection attempt might fail (found by Felix Antonius Wilhelm Ostmann).
• explicitly check for non-stream sockets in AE::Handle, too many clueless people fell into the trap of this somehow working.
• simplified and reworked the "OTHER MODULES" section.
• better/more condvar examples.

5.261 Wed Apr 28 16:13:36 CEST 2010

• AF_INET6 was not properly used from Socket6 during configuration time (found by Andy Grundman).

5.26 Mon Apr 12 04:49:35 CEST 2010

• don't generate spurious readyness notifications when select returns EINTR in the pure perl backend (analysed and testcase by Bas Denissen).
• give same examples in SYNOPSIS sections of AnyEvent and AE.
• provider faster implementations for AE::time/now/now_update for EV and Perl backends.
• provide faster AE::cv and AE::time implementations for all backends.
• no longer support lower/mixed-case signal names (this was never documented nor universally supported).
• some more memory µ-optimisations, and somewhat less messy code to cope with both AnyEvent and AE APIs.

5.251 Sat Mar 13 00:58:21 CET 2010

• make test failed if it was run before make install on perl <= 5.8.8, and older versions of perl make our live very difficult, so write constants.pl during Makefile.PL time.

5.25 Sat Mar 13 00:23:14 CET 2010

• fix a race condition in AnyEvent::Handle that would cause a "bio_read: unsupported method" error (in another ssl connection) after user code threw an exception.
• added AnyEvent::Handle->destroyed method.
• speed up AnyEvent::Socket::format_address and ::format_ipv6.
• the AnyEvent::Util::fh_nonblocking function worked only by lucky accident on win32.
• smaller and faster AnyEvent::Util::fh_nonblocking.
• when the (required!) Time::HiRes module is missing, AnyEvent did not fall back to built-in time properly.
• do not load Fcntl at runtime, saving memory and loading time.
• precompile a number of constants and use them instead of runtime detection and eval.
• free detection code after detection and similar memory optimisations.
• Perl backend timer interval best effort drift has been improved (same algorithm as EV).
• update unicode idna mapping table.

5.24 Tue Jan 5 11:39:43 CET 2010

• cygwin never reports errors from failed connects. 1.5 just gives you continous readyness and EAGAIN, 1.7 is even more broken and just hangs. work around both issues in a cygwin-specific hack.
• improve idle watcher documentation slightly.

5.23 Sun Dec 20 23:48:00 CET 2009

• support IDNs in resolve_sockaddr, and therefore in tcp_connect.
• implement punycode_encode/decode, idn_nameprep, idn_to_ascii and idn_to_unicode operations in AnyEvent::Util.
• provide $AE::VERSION.
• removed traces of "no strict 'refs'".

5.22 Sat Dec 5 03:51:13 CET 2009

• downgrade-or-fail in AnyEvent::Handle::push_write, to diagnose encoding failures earlier and more succinctly. (this works around bugs in perl, throwing away encoding info when passing scalar data to extensions).
• add more examples to AnyEvent::Socket manpage.
• upgrade internal warning set to the same as common::sense 2.03.
• use pack "n/a*" for pre-5.8.9 perl compatibility in AnyEvent::DNS (John Beppu).
• AnyEvent::Socket::inet_aton now properly supports ipv6, as documented.
• add google public dns servers to fallback server set and make sure we load-balance properly between the three sets. also add all fallback dns servers, not just a random one, to each dns config.

5.21 Thu Nov 19 02:48:47 CET 2009

• fix a problem where socket constants were called with parameters (spotted by David Friedland).
• fork_call never use'd POSIX (reported by Daisuke Maki).
• improve perl 5.6 compatibility further (but it still won't work unless you rip out everything but the core).
• prefer Net::DNS::Resolver over ipconfig, if installed, on win32. uses 10MB of RAM, but doesn't open a console window. sigh.

5.202 Wed Oct 14 22:35:44 CEST 2009

• AnyEvent::DNS would unexpectedly clobber $ under windows (analysed by Matthias Waldorf).
• AnyEvent::Handle::runcmd can now pass the PID of the newly-created process, which is much less useful than it might sound (based on patch by Yann Kerherve).

5.201 Tue Sep 29 12:09:25 CEST 2009

• AnyEvent:Handle::on_starttls/on_stoptls methods were broken (reported by Torsten Foertsch).
• common::sense 2.0 could cause tcp_server to throw an exception (analysed by elmex).

5.2 Mon Sep 14 07:04:49 CEST 2009

• INCOMPATIBLE CHANGE: do no longer support register_read_type and register_write_type in AnyEvent::Handle, instead support package names (the facility was mostly abused).
• implement "packagename-as-read/write type" support in AnyEvent::Handle.
• AnyEvent::Handle: new options "keepalive" and "oobinline".
• oobinline set by default to avoid security issues.
• the pure-perl event loop backend wrongly detected times() fallback support (spotted by Pavel Boldin).

5.12 Tue Sep 1 20:26:50 CEST 2009

• be more lenient when parsing resolv.conf files, as some people use hashmarks as comment indicator inside directives (reported by Michael S. Fischer).
• use same set of warnings as common::sense 2.0.
• fix a potential 32 bit overflow issue due to perl having problems with large hex constants in the Perl backend.
• do not use the slower 5.6 version fo the enc_name code in AnyEvent::DNS by default.
• fix some prototypes.
• (optionally) require Async::Interrupt 1.02.
• replace opendns fallbacks by verizon/level3 public dns servers.

5.112 Fri Aug 21 13:59:04 CEST 2009

• AnyEvent::Handle could cause hard crashes in Net::SSLeay when using starttls with an illegal/uncreatable tls context.
• port to broken win32 perls.

5.111 Sun Aug 16 18:44:36 CEST 2009

• perl errornously requires sockaddr_un structures returned by the kernel to have a specific length. work around this bug by padding sockaddr_un structures (found to fail on OS X, as perl only uses the correct code for GNU/Linux, but likely to fail on other OSes as well).

5.11 Wed Aug 12 17:49:37 CEST 2009

• fixed a bug in run_cmd with input from filename.
• create a json coder object when none is given in write direction to reduce dependency on JSON.

5.1 Tue Aug 11 03:17:32 CEST 2009

• tcp_connect now reports the correct error in $!, not an unrelated one (was broken since 4.91).
• AE::Handle did not properly clear rtimeout/wtimeout watchers when retrying a tcp_connect.
• new functions: AnyEvent::Util::run_cmd and close_all_fds_except.
• fixed wrong documentation in AE::Socket.

5.01 Mon Aug 10 03:16:32 CEST 2009

• last release broke EV child watchers :/.

5.0 Sun Aug 9 17:32:09 CEST 2009

• officially introduce and document the AE API.
• lowering the timeout at runtime did not have immediate effect in AnyEvent::Handle.
• AE::Handle now has separate and independent read and write timeout settings.
• probe for Guard module when AnyEvent::Util is loaded, not at runtime (Event doesn't like eval "use" from callbacks, and it avoids exporting the probe function).
• Impl::IOAsync's io watchers did not use the filehandle emulation code to work around it's watcher limits.
• work around IO::Async's problems with overloaded objects.
• try to disable wearnings inside IO::Async, it's just too buggy.
• do no longer use Event by default, only EV or Perl, Event is too buggy.
• hackishly provide fast AE:: interface when EV or Perl is the backend.
• inherit VERSION from AnyEvent::VERSION in most modules.

4.91 Thu Aug 6 15:42:45 CEST 2009

• AE::Handle::starttls could get out of sync when the read buffer already contains some TLS handshake.
• AE::Handle did not properly free the TLS session, causing bigger memory leaks in Net::SSLeay than expected (reported by toaster).
• AE::Socket::tcp_connect will now artificially delay invoking the callback to avoid returning after invoking the callback.
• convert many internal watcher uses to AE API.

4.9 Sat Aug 1 11:07:01 CEST 2009

• Glib silently fails when registering a timeout with a negative value, so avoid that.
• call condvar callback immediately when it is set after the condition is already signalled.
• check rbuf_max condition only after trying to consume data.
• normalise signal numbers to names when using the ae's signal handling, but do not document this (yet).
• pure perl signal emulation did not properly set nonblocking mode on the signal pipe on win32 (this is unlikely to have caused any issues).
• new module: AnyEvent::Debug.
• AnyEvent::Strict now checks that a signal was specified by name (not name or number).
• reduce memory footprint in typical cases by ~50kb by only compiling signal code when necessary.
• add AnyEvent::Handle->rbuf_max.
• grab the AE namespace for future new API, implement stubs for said future/alternative API.
• new function: AnyEvent::Socket::format_hostport.

4.881 Tue Jul 28 12:51:53 CEST 2009

• work around a bug in local in pre-5.10 perls, causing AnyEvent::Handle to recurse when it should not (analysed by elmex).

4.88 Tue Jul 28 04:04:37 CEST 2009

• re-bless the handle into a dummy package after calling AnyEvent::Handle::destroy, so the user does not need to check for errors after every push_write etc.
• do not attempt to run t/02_signals.t on obviously broken platforms.

4.87 Sun Jul 26 02:06:16 CEST 2009

• do not attempt to linger when there is no longer a valid fh.
• enforce tls mode to be either accept or connect, do not simply segfault in Net::SSLeay.
• AnyEvent::Handle can now call tcp_connect itself (new parameters connect, on_prepare, on_connect and on_connect_error). Updated tutorial accordingly.
• add AnyEvent::Impl::Irssi backend.

4.86 Mon Jul 20 23:52:29 CEST 2009

• since the verbose warning is not enough, explicitly document that versions before 1.33 of Net::SSLeay are not secure.
• work around signal handling races in Event and (...) Event::Lib.
• try to align signal-race timer to full-second boundaries.
• work around Tk not liking negative timeouts.
• don't complain of different grades of environmental unfriendlyness in IO::Async.

4.85 Sat Jul 18 06:16:14 CEST 2009

• nail the signal race problem in perl once and for all (see $AnyEvent::MAX_SIGNAL_LATENCY).
• take advantage of Async::Interrupt if it is available.
• load Time::HiRes and Guard modules on demand only.
• add optional/recommended modules section to AnyEvent documentation.
• reduce memory usage considerably (and reduce startup penalty) by not using "strict", "warnings" and "overload" modules.
• work around buggy windows/openbsd perls and provide EBADMSG and EPROTO ourselves when missing.
• improve perl 5.6 compatibility of the core event loop.
• made Net::SSLeay version 1.33 a soft requirement.

4.83 Fri Jul 17 16:56:26 CEST 2009

• implement AnyEvent::Socket::getprotobyname.
• AnyEvent::CondVar's will now detect recursive blocking waits and will croak, as too many people fall into this trap.
• AnyEvent::Handle will now call ->destroy on itself after executing the on_error callback, instead of doing some half-baked internal shutdown, for fatal errors.
• clarify on_eof behaviour w.r.t. the read queue and on_read callbacks.
• ignore some possible spurious wake-ups in tcp_connect.

4.82 Sat Jul 11 00:34:55 CEST 2009

• POE and Event backends didn't accept some callable objects as callbacks.
• use Config module instead of POSIX module to detect signal names in AnyEvent::Strict and AnyEvent::Impl::EventLib, as the POSIX module doesn't even have all POSIX signals :/.
• use more workarounds around the many refcnt/corruption bugs in Event::Lib.
• work around a race condition in perl's select, causing t/03_child.t to rarely fail.

4.81 Thu Jul 9 10:30:30 CEST 2009

• AnyEvent::Handle didn't properly diagnose write errors (it expected -1 from syswrite, how lame... :).
• support file descriptors in addition to file handles in AnyEvent->io.
• new env variables: PERL_ANYEVENT_RESOLV_CONF, PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE and PERL_ANYEVENT_CA_PATH.
• provide a sensible synopsis section for AnyEvent::TLS.
• add a "supported backends" section to the manpage.
• added simple io watcher test to testsuite, using a portable_socketpair.
• tried to improve the stability of the Event::Lib backend, YMMV.

4.8 Mon Jul 6 23:45:16 CEST 2009

• AnyEvent::DNS did not properly follow CNAME records with uppercase targets.
• AnyEvent::DNS would errornously return AAAA records with v4 mapped addresses (a faulty record) as ipv4 addresses, causing AnyEvent::Socket to throw an exception.
• added new module AnyEvent::TLS for easier SSL/TLS context creation, with many options including hostname verification, secure default configuration, lots of documentation and, predefined diffie-hellman keys for perfect forward security and much more. get it while it's still fresh!
• use AnyEvent::TLS in AnyEvent::Handle for context management.
• load AnyEvent::Handle only on demand in AnyEvent::DNS, so AnyEvent::Socket users have smaller memory footprint in the common case.
• add AnyEvent::Handle->push_shutdown method.
• add an additional error message parameter to AnyEvent::Handle's on_error callback (for TLS, $! is still available).
• add AnyEvent::Handle on_starttls/on_stoptls callbacks.
• make AnyEvent::Handle more robust against early conenction failures (during new), and return C<undef> in that case from the constructor.
• AnyEvent::Handle will now try to load only JSON::XS first, then fall back to JSON.
• format_ipv4/format_ipv6 are now exported by default, for symmetry, and because it was documented that way.

4.451 Fri Jul 3 00:28:58 CEST 2009

• do not clear rbuf when shutting down an AnyEvent::Handle object - doing so breaks AnyEvent::HTTP.

4.45 Mon Jun 29 22:59:26 CEST 2009

• a write error could cause AnyEvent::Handle to create an I/O watcher with an undefined $fh.
• special-case mapped ipv4 addresses in both AnyEvent::Socket::format_address and parse_address, to treat them just like ipv4 addresses.
• updated and overhauled the AnyEvent::Intro doc.
• implement AnyEvent::Socket::format_ipv4/ipv6.
• slightly speed up portable_pipe/socketpair.
• expand condvar begin/end documentation.

4.42 Fri Jun 26 08:32:18 CEST 2009

• preliminary and neccesarily incomplete support for IO::Async.
• reset SIGCHLD to DEFAULT when AnyEvent is loaded, in case it was set to IGNORE, to ensure we can catch child statuses even when the calling env acts stupidly.
• updated benchmarks with IO::Async, which performs very well.

4.412 Wed Jun 24 01:35:57 CEST 2009

• support an "untaint" attribute for AnyEvent::DNS and set it on the default resolver.
• implement and document AnyEvent::Impl::Perl::loop.
• remove all anyevent-env variables from %ENV when running in tainted mode.
• mention and extend the IO::Lambda benchmark.

4.411 Sun Jun 7 18:48:02 CEST 2009

• do not try to use F_SETFD on windows.

4.41 Thu May 14 06:40:11 CEST 2009

• work around issues in older perls (5.8.0?) when a signal handler is deleted from the %SIG hash.
• use POSIX::_exit in child test, to avoid running destructors.
• speed up CHLD handling by relying on SIGCHLD being synchronously delivered, even when we roll our own implementation.
• AnyEvent::DNS: add the "dname" resource record name for cosmetic reasons.

4.4 Sun Apr 26 20:12:33 CEST 2009

• implemented idle watchers, where applicable.
• AnyEvent->time died when Event backend was in use.
• fix a memleak in the Tk backend.
• sped up Tk timer handling.
• clip negative "after" values to 0 in AnyEvent::Impl::Event to avoid spamming out warning messages.
• fix Qt timers without interval.
• avoid Qt zero-timeout special case, in old libqt's.

4.352 Mon Apr 20 16:31:11 CEST 2009

• fix AnyEvent::Strict error messages for child watchers.
• fix/update Makefile.PL "recommends" versions.
• add AnyEvent->now_update.

4.351 Sat Apr 11 07:56:14 CEST 2009

• actually make the signal pipe work under win32.
• localise $! in signal handler to avoid changing $!, although perl itself does not seem to save/restore errno either.
• set the cloexec flag on the signal pipe (normally set by perl too).

4.35 Fri Mar 27 11:48:20 CET 2009

• event models relying on AnyEvent's signal watcher emulation did invoke the callback asynchronously, contradicting documentation and causing signals to get lost (this includes AnyEvent's own event loop). AnyEvent now uses the standard pipe trick to make callback execution synchronous to the event loop.
• AnyEvent::Handle didn't free TLS context data on DESTROY (patch by Pavel Shaydo).
• work around the ever-incompatibly-changing API of MakeMaker.
• document that changing global variables without restoring them is a bad idea in Perl (noted by Adam Rosenstein).
• AnyEvent::Strict now barfs if ->io is passed a file.

4.34 Thu Feb 12 18:32:45 CET 2009

• separately buffer TLS read data, as otherwise the read queue could deadlock as receiving data is not expected while draining the read queue (which cna only happen with TLS).
• raise EBADMSG error on JSON decoding errors.
• fix some minor manpage bugs (reported by Maximilian Gaß).
• speed up select bitmask parsing quite a bit in the pure perl backend.
• use CORE::select instead of just select in AnyEvent::Impl::Perl.

4.331 Tue Jan 6 21:07:25 CET 2009

• socketpair fails on many vista machines because vista has completely broken accept/getpeername and getsockname functions, so we provide our own socketpair emulation that kind of works (AnyEvent::Util::portable_pipe).
• new function: AnyEvent::Util::portable_socketpair.
• take advantage of the Guard module if it exists.

4.33 Fri Nov 21 02:35:40 CET 2008

• AnyEvent::Strict did errornously flag a fileno of 0 as illegal.
• reduce memory usage and slightly speed up the pure perl backend by only storing the file descriptor, not the file handle.
• add missing autocork method to AnyEvent::Handle (reported by Adam Rosenstein).
• AnyEvent::DNS->resolve errornously documented an $rcode result argument, but there isn't (spotted by Henrik Krohns).
• the naked truth about Tk - it's basically unmaintained.

4.32 Mon Nov 3 22:46:32 CET 2008

• fix AnyEvent::Socket::resolve_sockaddr to properly support unix sockets again and choose a proper default for the socket type.
• fix call to resolve_sockaddr in tcp_connect.

4.31 Thu Oct 30 04:41:48 CET 2008

• implemented AnyEvent::Handle->destroy method.
• hint about unexpected effects in TLS mode.
• speed up AnyEvent::Impl::Perl by using more arrays instead of hashes without the slightest loss of readability :)
• work around a perl argument refcounting bug.
• with some perl patches applied, AnyEvent now seems leak-free.

4.3 Fri Oct 3 09:18:43 CEST 2008

• AnyEvent will now install a no-op signal handler for SIGPIPE, unless one has been installed already.
• warn about not loaidng AnyEvent::Impl::POE early enough (patch by Adam Rosenstein).
• fixed a great number of bugs and corner cases in AnyEvent::Handle.
• fix a bug in where in SSL connect mode, the client would first wait for some data by the server and otherwise hang. (reported and analysed in an absolutely exemplary manner by Adam Rosenstein).
• fix a bug in where SSL EOF would not be treated as stream EOF, putting the connection into a hung state. (reported and analysed in an absolutely exemplary manner by Adam Rosenstein).
• fix a potential segfault when the TLS context would go missing in a read callback (e.g. due to stoptls) - Net::SSLeay of course makes no type checking whatsoever.
• AnyEvent::Handle will not stop the read watcher in TLS mode.
• AnyEvent::Handle->stoptls will send a TLS close notify instead of simply destroying the stream now.
• fix a bug where large blocks of data written in TLS mode would not be sent unless triggered by receives.
• on_drain will now take the tls write buffer into account.
• SSL operations have been streamlined a bit and should be faster now, more to come, though.
• added a FAQ section, will document nontrivial issues in there.

4.234 Mon Sep 29 04:08:13 CEST 2008

• fix child watcher documentation: only child exits will be reported, no trace events.
• mention SIGPIPE in AnyEvent::Handle.
• perl backend will now use POSIX::times as monotonic clock when available and the monotonic clock option is not.
• run even without Time::HiRes in some cases now, but do not provide sub-second accuracy (all supported perl versions have Time::HiRes).

4.233 Fri Aug 22 01:48:05 CEST 2008

• fix a bug in the testsuite, causing a hang.
• clarified lots of AnyEvent::Handle constructor arguments.

4.232 Thu Aug 21 20:44:25 CEST 2008

• fix a bug in AnyEvent::Handle that could cause two fatal error callbacks on EOF, which caused AnyEvent::HTTP to signal success twice (testcase by Leon Brocard).
• clarified on_eof/on_error documentation a bit.

4.231 Tue Jul 29 13:12:15 CEST 2008

• remove some debugging code left in AnyEvent::Util::fork_call (and no, it's impossible to implement with the broken windows perls without resource leaks or worse).

4.23 Tue Jul 29 12:19:59 CEST 2008

• document the first parameter passed to condvar callbacks to be the callback.
• add AnyEvent::Socket::{ntoa,aton} aliases.
• optimize the AE::Handle->push_read (line) for the default eol marker.
• optimize push_read (packstring|storable) for small packets.
• invoke on_error callback when no on_eof callback is set.
• fix a bug in push_read (storable) of unknown impact.

4.22 Sun Jul 20 16:34:13 CEST 2008

• new function AnyEvent::Socket::parse_hostport.
• as the bulkheads at microsoft can't even get getprotobyname reliably working on their shitty fucking broken os we need to hardcode some common protocol numbers in AnyEvent::Socket. How can people even bother with such a pile of shit as windows.

4.21 Thu Jul 17 14:40:05 CEST 2008

• INCOMPATIBLE CHANGE: AnyEvent::Util::fork_call now has a prototype which is incompatible to previous invocation syntax.
• work around more windows perl bugs in fork_call. I cannot imagine why anybody would bother implementing fork in such an obviously unusable way.
• avoid calling $do_retry if the request has already finished in AnyEvent::DNS, thus avoiding an exception (reported by Anatoly K. Sharifulin).

4.2 Sat Jul 12 22:42:11 CEST 2008

• support an "interval" argument for repeating timers.
• fix a bug in the pure perl event loop that caused timers to be delayed under some circumstances.
• implement optional argument checking via PERL_ANYEVENT_STRICT.
• not importing anything from Event causes it to malfunction and not use Time::HiRes, work around this bug.
• more bug workarounds against the endlessly broken Tk module, seems to work now on 32 bit machines, but less so on 64 bit.
• minor optimisations applied to most backends.

4.161 Fri Jul 4 14:24:48 CEST 2008

• fixed the t/handle/02_write.t, it read after write, with the assumption that all data could be written before read (reported by Jim Razmus).

4.160 Thu Jul 3 04:02:21 CEST 2008

• re-registering signal watchers after unregistering one did not work if a backend falls back on AnyEvent's default implementation (also affected child watchers).
• new AnyEvent::Handle options: autocork and no_delay.

4.152 Sun Jun 22 14:15:44 CEST 2008

• allow for 32-bit perls that implement shifts differently on different architectures in parse_ipv4 (reported and analysed by Keiichi DAIBA).

4.151 Fri Jun 6 17:34:24 CEST 2008

• make sure specifying only on_read and never pushing reads works.

4.15 Fri Jun 6 13:00:46 CEST 2008

• the pure perl backend would keep some watchers alive when more than one watcher was registered for the same fd.
• new "packstring" and "storable" read and write types for AnyEvent::Handle.
• allow on_eof handler to be called after on_error with EPIPE returns.
• do not immediately call on_read callback in handle constructor.

4.14 Thu Jun 5 20:29:31 CEST 2008

• Fixed a bug in DNS SRV priority sorting.
• AnyEvent::Util::guard now reports runtime errors while executing the guard block as warnings.
• handle 0-byte-reads just before EOF correctly in AnyEvent::Handle.

4.13 Thu Jun 5 00:47:59 CEST 2008

• AnyEvent::DNS only followed cname chains with length 2, contrary to documentation. bumped it up to 10, thanks to microsoft, the current broken-dns-config-king.
• AnyEvent::DNS didn't check for socket return status but instead relied on perl not creating filehandles in that case - too bad it gives you a bogus file handle (reported and analysed by Vladimir Timofeev).
• fix queue management logic in AnyEvent::Handle: when on_read was registered, the queue was empty and no progress could be made AnyEvent::Handle would enter an endless loop.
• correctly start reading again when the handle became busy again after idling.
• correctly treat tls shut-downs as EOF condition (for the time being, would be nice to have a callback for that).
• correctly call eof callback under all conditions (hopefully).
• the timeout callback did not expect that $self can go away any time.

4.12 Tue Jun 3 10:58:04 CEST 2008

• include AnyEvent::Intro, a tutorial for anyevent, anyevent::socket and anyevent::handle.
• allow more options in on_error.

4.11 Fri May 30 23:42:25 CEST 2008

• INCOMPATIBLE CHANGE: replace ptr by real PTR lookup, provide reverse_lookup and reverse_verify to replace it, support v4mapped and v4compat addresses.
• provide more documentation for the resolver class.

• support NAPTR record name and decode it.
• implement random weight sampling for SRV records, as per rfc 2782.
• correctly abort on srv-record targets of ".".
• added AnyEvent::DNS::wait_for_slot.

• plug a probable memleak in the DNS vc code.
• use configured timeout also for VC request phase.
• implement timeout and max_outstanding methods for resolver class.
• update version numbers in all modules.

4.1 Thu May 29 05:45:40 CEST 2008

• INCOMPATIBLE CHANGE: renamed xxx_ip functions to xxx_address which mirrors their purpose better (old names still available for a while). Also moved AnyEvent::DNS::addr to AnyEvent::Socket::resolve_sockaddr.
• implement AnyEvent->time and AnyEvent->now.
• fix IPv6 support in pack_sockaddr.
• officially un-experimentalise all newly introduced code.
• support unix domain sockets everywhere by specifying a host of "unix/" and the pathname as service.
• implement an activity timeout in AnyEvent::Handle.
• added a regex read type to AnyEvent::Handle.
• added a json read/write type to AnyEvent::Handle.
• always croak in on_error in AnyEvent::Handle.
• document how to subclass AnyEvent::Handle.
• implement AnyEvent::Util::fork_call.
• add support for IPv6 nameservers and nameserver statements.
• work around yet another windows perl bug in where empty select masks cause errors in the pure perl backend (this workaround cannot be implemented for the other event loops, but EV also works around this).
• supply AnyEvent::Socket::address_type and make good use of it.
• clarify and fix the Handle documentation w.r.t $self vs. $handle vs. callback arguments.
• add some recommends to the META.yml.

4.05 Mon May 26 19:44:06 CEST 2008

• some platforms ignore the rfc and prepend an extra sa_len member to the sockaddr structure, cater for those. also use sockaddr_family, didn't know it was there, but comes in handy for the workaround.
• undo the import WIN32 hack.

4.04 Mon May 26 08:03:31 CEST 2008

• try to work around yet another windows bug: failed connects are reported as if it were out-of-band data. windows users: you suck. Only EV, Glib, Event and the pure perl backend can handle this condition.
• optimize write algorithm in AnyEvent::Handle.
• properly parse PERL_ANYEVENT_PROTOCOLS and use the info correctly.
• tcp_connect now properly iterates through all targets.
• check wether IPv6 sockets can actually be created, otherwise, disable ipv6 support entirely. also hardcode some AF_INET6 constants for the sake of perl 5.8.
• vastly improved nameserver/suffix detection algorithm for windows (still a hack...)
• try to use a fallback dns server if no dns servers could be found.
• splatter around some local $SIG{__DIE__}'s to work around bad die handlers.

4.03 Sun May 25 05:05:57 CEST 2008

• support IPv6 in tcp_server.
• pass local hostname and port to the prepare callback in tcp_server.
• make types extendable in AnyEvent::Handle.
• croak, not die, in AnyEvent::Handle;

4.0 Sat May 24 19:58:08 CEST 2008

• added (experimental) AnyEvent::DNS module.
• added (experimental) AnyEvent::Socket module.
• added (experiemntal) support for TLS/SSL in AnyEvent::Handle.
• make condvar->end call ->send as documented.
• make condvar constructor support the documented cb => argument.
• overload condvars so you can use them instead of code references.
• support more of the POSIX forms instead of a pure dotted quad for verbatim ip addresses.
• AnyEvent::Socket::inet_aton will use AnyEvent::DNS now and not fork anymore.
• try very hard not to freeze on broken windows perls.
• make on_eof optional in AnyEvent::Handle.
• support service names in tcp_connect and tcp_server.
• work around netbsd/openbsd bug causing unix sockets not to become writable until empty.
• only make a dummy read for error detection when getpeername returns ENOTCONN.
• defend AnyEvent::Util::inet_aton against Coro::LWP's brutal override.
• new AnyEvent::Guard::cancel.

3.5 Sat May 17 23:17:14 CEST 2008

• gracefully deal with systems not defining CLOCK_MONOTONIC (as opposed to not supporting the clock itself, which worked in 3.41).
• added AnyEvent::Util::tcp_connect and AnyEvent::Util::tcp_server helpers, to replace the ill-designed AnyEvent::Socket class.
• added some examples (eg/connect, eg/handle).
• added AnyEvent::Util::guard.
• AnyEvent::Util now exports most of its functions.
• fixed a bug in readchunk, where the callback was called with $self as first and second argument.
• simplified and fixed regex handling in AnyEvent::Handle::readline.
• fix manpage condvars examples to use new syntax.
• considerably improve inet_aton with EV::ADNS backend to support cname chains (common dns configuration bug, e.g. with www.google.de) and aaaa records if no a record could be found.

3.41 Sun May 11 19:53:13 CEST 2008

• work around a bug in perl 5.8.8's local. Reported by Yi Ma Mao.

3.4 Sun May 11 00:29:25 CEST 2008

• complete re-implementation of condvars with a hopefully much more useful API (backward compatible functions exist but are undocumented).
• AnyEvent::Handle fully rewritten with a hopefully more powerful API (still subject to change).
• take advantage of CLOCK_MONOTONIC, if available, in AnyEvent::Impl::Perl.
• provide AnyEvent::post_detect and @AnyEvent::post_detect, which allows module authors to avoid forcing event loop detection. (used by Coro::AIO, Coro::BDB, Coro::AnyEvent for example).
• remove coro backends: Coro now provides generic support for AnyEvent via Coro::AnyEvent.

3.3 Mon Apr 28 09:51:06 CEST 2008

• added AnyEvent::Handle, AnyEvent::Socket and AnyEvent::Util modules.
• fix a bug in the pure perl backend that kept watchers alive when multiple watchers were registered for the same fh/poll combo.
• add a benchmark section showing AnyEvent overhead and comparing the different event loops with each other.
• prefer pure perl over tk when autoprobing, as it's about as fast, but doesn't crash with many watchers.
• declare Qt support non-experimental.
• clarify the confusing section about the file descriptor being kept alive.
• document the race between loading of an event module and child processes exiting.
• support POE as "backend" (with some caveats, POE is not generic enough, and darn slow).
• support Wx and Prima through POE.
• optimise perl backend to use 20% less memory and take advantage of typical timeout behaviour. It can now compete with select/poll-based C event loops in most cases (it is usually faster than Event and Glib :).
• roughly cut EV memory use in half and increase its speed by 30%, by removing undocumented functionality. Did something similar to other event loops where possible.

3.2 Thu Apr 24 10:10:40 CEST 2008

• do not die when anyevent watchers are destroyed while running callbacks in the pureperl backend (could only happen when two watchers are registered for the same fh/poll combo).
• support autoloading for child watchers, was broken in all versions.
• implement PERL_ANYEVENT_MODEL env variable.
• (experimental) implement interface to the (very crashy/buggy) Event::Lib module.
• (experimental) implement interface to the Qt module (cannot be autoprobed).
• this release is IO:AnyEvent-proof.

3.12 Tue Apr 22 07:11:46 CEST 2008

• reinstate AUTHOR section that got lost somehow.
• do not hang in the testsuite with badly broken perls (activestate, strawberry...), but instead diagnose the problem and continue.
• use INT instead of CHLD in an attempt to support broken windows perls better (this decreases the test quality, unfortunately).
• do not send the signal to the process group (no problem for CHLD, bad for INT :).

3.11 Sat Apr 19 06:57:31 CEST 2008

• major documentation rework.
• document the fact that child watchers only watch for zombies.
• fix the child watcher example.

3.1 Wed Apr 16 17:09:01 CEST 2008

• work around recurring bugs in Tk by dup'ing filehandles, the only method with good success chances on Tk (the bugs apparently don't get fixed anytime soon).
• lift the restriction of only one watcher per fh direction (as the Tk bug workaround also lifts it and only Tk imposed such strong limits).
• changed probe order to prefer coro adaptors.
• explain why recursion into the event loop is not supported unless the backend supports it (only Coro::EV does without any restrictions...).
• add simple manpages for all backend modules.

3.0 Mon Apr 7 21:30:23 CEST 2008

• Coro::Signal changed semantics, roll our own, also cleaning up the Coro implementation in general.
• rename Coro backend to CoroEvent.
• add some decision helping paragraph to the manpage that should help people to decide whether AnyEvent is the right thing for them.

2.9 Mon Jan 28 13:31:54 CET 2008

• update for EV 3.0 API changes.

2.8 Sun Nov 25 15:06:03 CET 2007

• waitpid can validly return 0. accept this fact of life instead of reporting it to any watchers.

2.7 Fri Nov 23 11:41:14 CET 2007

• force use of AnyEvent::Impl::Perl in testsuite, there is too much breakage outside AnyEvent.
• deliver signals synchronously in AnyEvent::Impl::Perl or any other event loop that relies on AnyEvents child watcher emulation. Could help with hanging testsuite (except when Event or EV are installed).

2.6 Fri Nov 9 20:36:35 CET 2007

• fix bug in testsuite.
• move EV adaptor modules to AnyEvent.
• add Coro+EV adaptor module.

2.55 Tue Nov 6 17:41:32 CET 2007

• add EV to the list of supported event models.
• do not auto-reset pid watchers, pass pid and status to them.
• allow a pid of zero to watch for all children in child watchers.

2.54 Wed Jul 18 17:36:23 CEST 2007

• work around a perl bug that results in BEGIN not safe after errors--compilation aborted without any discernible reason or error message by once again not use'ing strict.

2.53 Sun Jul 8 10:51:53 CEST 2007

• make Glib interface work again (spotted by elmex).

2.52 Wed Mar 7 18:36:16 CET 2007

• child watchers stopped working permanently when all current child watchers were destroyed.

2.51 Mon Dec 11 21:33:24 CET 2006

• work around bugs in perl where eval "require Module" returns true even if the module couldn't be loaded :/.

2.5 Mon Dec 11 02:15:28 CET 2006

• avoid $AUTOLOAD because many perls corrupt it.
• AnyEvent::detect forces autodetection.
• implement signal watchers (experimental) (Tk does not support async signals (<= 804.027 at least), so they might get delayed indefinitely on Tk).
• implement child watchers (experimental).
• moved default condvar implementation into base module, simplifying most implementation modules.

2.1 Fri Nov 24 15:50:48 CET 2006

• better docs.
• simple testsuite.
• added AnyEvent->one_event method for special purposes.

2.0 Wed Nov 1 02:21:30 CET 2006

• INCOMPATIBLE CHANGE: poll can now either be "r" or "w" but not both.
• INCOMPATIBLE CHANGE: io watcher callbacks have no arguments anymore.
• EXPERIMENTAL: new pure-perl model added, AnyEvent now always finds a suitable event model.
• improved documentation.
• reduced cpu overhead.

1.02 Fri Jan 13 14:15:40 CET 2006

• add COPYING to clarify license.

1.01 Sun Jan 8 05:48:09 CET 2006

• correctly cancel Event timers, avoid memory leaks.

1.0 Sun Jan 8 05:40:58 CET 2006

• allow third-party interfaces to be added at runtime.
• fix version number.

0.9 Fri Dec 30 02:25:41 CET 2005

• fixed errors in the documentation.
• going back to using $VERSION as "load check", as suggested by Jörn Reder. Let's see why I stopped using this method.
• add 'hup' to the list of events to receive for glib and generate 'rw' events for it, as some versions of glib seem to require this, while this breaks other (older) versions of glib.
• implemented PERL_ANYEVENT_VERBOSE env variable.

0.3 Sun Dec 4 10:43:33 CET 2005

• no changes to the code.
• fixed documentation.
• clarified some corner cases.
• vastly improved documentation with a long example.

0.2 Thu Dec 1 22:18:49 CET 2005

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

0.1 Thu Dec 1 19:44:57 CET 2005

• spiced up and cleaned up for release.

0.01 Tue Sep 21 18:12:09 CEST 2004

• original version; copied from Convert::Scalar.
