7.17 Wed Sep 18 03:04:49 CEST 2019
- work around antique openssl version in RHEL 7 by formatting
dh parameters differently (reported by several people).
- add t/13_weaken.t.
7.16 Fri Jul 19 18:00:21 CEST 2019
- add ffdhe group dh parameters from RFC 7919, and use ffdhe3072
as new default, instead of schmorp1539.
- AnyEvent::Log did not reassess logging status of
AnyEvent::Log::logger's when contexts were changed with
->attach/detach/slaves, causing them to not log even though a
recent attach should have caused them to log.
- added some more logging configuration examples.
- mention RFC 8482 in AnyEvent::DNS.
7.15 Tue Feb 26 03:07:42 CET 2019
- INCOMPATIBLE CHANGE: AnyEvent::Handle's tls_detect documentation gave
separate major and minor versions, while code passed only a single
value. This version follows the documentation and now passes separate
major and minor values.
- work around Net::SSLeay not having been ported to openssl 1.1, but many
distributions compiling it against openssl 1.1, which unfortunately
succeeds and results in a very broken module.
- AnyEvent::DNS::dns_unpack now stores the original DNS packet
in the __ member, to allow decoding of undecodable resouce records
containing compressed domian names.
- AnyEvent::Socket::parse_ipv6 would NOT, as advertised, accept ipv4
addresses. It now does and converts them to ipv4 mapped addresses.
- support CAA records, based on patch by Steve Atkins.
- add freenom and cloudflare nameservers as dns fallback.
- AnyEvent::Strict would not properly ward against io watchers
on files when the handle passed was a file descriptor.
- document "internal" variables used by the dns en-/decoder to allow
enterprising users to extend them in a semi-official way.
7.14 Sat Jun 24 01:44:19 CEST 2017
- fix a crash bug in AnyEvent::Handle with openssl 1.1.0 (patched
by Paul Howarth and apparently tracked down by Mike McCauley).
- AnyEvent::Handle->keepalive was documented (and defined) twice
(found by Matt Merhar).
- AnyEvent::Socket::tcp_bind/tcp_server would immediately unlink a unix
listening socket unless a guard is used. Change this so that no
cleanup will be performed unless a guard is used and document this more
clearly.
- make tcp_bind/tcp_server error messages more regular.
- work around latest perl upstream breakage - this time, perl5porters were
apparently bullied by a bogus CVE (CVE-2016-1238), and since distros
stupidly apply anything that has "security fix" stamped on it, it's likely
going to be a problem in practise (and working around it is trivial on
windows and unix).
- add TCP_FASTOPEN/MSG_FASTOPEN and MSG_NOSIGNAL/MSG_MORE/MSG_DONTWAIT
to constants.
- update warnings to common::sense 3.74 standards.
7.13 Sat Sep 17 04:31:49 CEST 2016
- Only call tlsext_host_name for non-empty common names (reported
by Maxime Soulé).
- log a (single) notice message if SNI is not supported.
- upgrade to UTS-46:9.0.0 draft and switch to non-transitional
behaviour, beating thunderbird, ie, edge, chrome and safari to it :)
(see also https://bugzilla.mozilla.org/show_bug.cgi?id=1218179)
- turns out the UTS-46 IDNA testcase failures were indeed bugs in the
testcases and the specification and not in the code - the post-9.0.0
unicode files have all known problems fixed, so finally the AnyEvent
IDNA implementation can pass the full IDNA testsuite - without needing
a single fix :)
- guarantee (and document) that condvar callbacks will be removed
on invocation - important to avoid circular references.
7.12 Wed Jan 27 19:12:26 CET 2016
- use common name as hostname for tls connects, if Net::SSLeay
supports SNI.
- fix documentation of tls_autostart read type in AnyEvent::Handle,
analyzed by Felix Ostmann.
7.11 Thu Jul 16 14:36:00 CEST 2015
- AnyEvent::Socket::parse_ipv6 could accept malformed ipv6
addresses (extra "::" at end and similar cases).
- add a more explicit warning to AnyEvent::Handle that it doesn't
work on files, people keep getting confused.
- new function AnyEvent::Socket::tcp_bind.
- new functions AnyEvent::fh_block and AnyEvent::fh_unblock.
- aligned ipv6 address formatting with RFC 5952 (by not shortening
a single :0: to ::).
- added stability canary support.
7.09 Sat May 2 16:38:53 CEST 2015
- AnyEvent::Debug called an internal function (AnyEvent::Log::ft)
that was renamed to AnyEvent::Log:format_time. uinder its old name
(analyzed by Michael Stovenour).
- update AnyEvent::DNS fallback resolver addresses:
seems google effectively killed most other free dns resolvers,
so remove them, but add cable and wireless (ecrc) since it was
stable for 20 years or so, official or not, and there should be
an alternative to google.
- perl5porters broke windows error codes in 5.20, and mapped
WSAEWOULDBLOCK on the (different) EWOULDBLOCK error code, and
WSAEINPROGRESS into the incompatible ERINPROGRESS code, probably
because they were so cool. They probably broke other error codes
of the context as title.
- AnyEvent::Strict would not restore read-write access to $_ when a callback
died - this is a user bug, but since AE::Strict exists to help dbeugging...
- detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
to work with it - the author is well aware of the issues but refuses
to fix them. This extreme step has been taken because the module actively
attacks the goals of AnyEvent and makes it harder for module authors to use
AnyEvent.
6.02 Fri Aug 26 20:08:31 CEST 2011
- log_to_syslog now accepts facility strings.
- log_to_syslog would not allow facilities - "$facility|$level"
*literally* means that string. sheesh.
- the CPAN parser got confused and thought we provide Sys::Syslog, try
to work around.
- renamed AnyEvent::Impl::FLTK2 to FLTK.
6.01 Fri Aug 26 07:04:11 CEST 2011
- INCOMPATIBLE CHANGE: AnyEvent::DNS resource records now include
the TTL as fourth element - this affects ->resolve, ->request
and ->dns_unpack indirectly. Convenience functions such as
AnyEvent::DNS::{a,txt,mx,srv} are not affected, neither is
AnyEvent::Socket.
- INCOMPATIBLE CHANGE: backend authors now should not implement
one_event or loop, but instead the AnyEvent::CondVar::_wait and _poll
methods.
- INCOMPATIBLE CHANGE: verbosity levels have been redefined, see
AnyEvent (PERL_ANYEVENT_VERBOSE) and AnyEvent::Log for details.
- DEPRECIATION: please change
"use AnyEvent::Impl::Perl" to "use AnyEvent::Loop" and
"AnyEvent::Impl::Perl::loop" to "AnyEvent::Loop::run"
in your programs, for future compatibility.
- *blush* idle watcher emulation was borked.
- AnyEvent::Strict now checks the AE::xxx functions as well.
- querying too long domain names would barf deep inside AnyEvent::DNS - since
this is hard to avoid for applications, AnyEvent:.DNS::request now checks for
for too long domain names explicitly and passes an undef to the callback
instead (reported by James Bromberger).
- make AnyEvent::Util more robust against EINTR (analyzed by Andrew Suffield).
- new functions: AnyEvent::postpone, AnyEvent::log.
- new module: AnyEvent::Log, for simple logging needs.
- new env variable, PERL_ANYEVENT_LOG, for fine-grained logging config.
- new env variable, PERL_ANYEVENT_DEBUG_SHELL, to automatically start
a debug shell.
- new env variable, PERL_ANYEVENT_DEBUG_WRAP, to automatically enable
watcher instrumentation/wrapping (see AnyEvent::Debug::wrap).
- new env variable, PERL_ANYEVENT_HOSTS, to override the place where
/etc/hosts can be found.
- an empty PERL_ANYEVENT_RESOLV_CONF now selects the default
configuration.
- env variables can now be specified using AE_xyz instead of
PERL_ANYEVENT_xyz, subject to some rules.
- lots of new AnyEvent::Debug functionality.
- AnyEvent::Strict now checks for modifications of $_ by the callback
(by setting it to readonly while executing the callback, if possible).
- IO::Async sometimes cancels the wrong timer when you call cancel_timer.
Invest extra overhead to work around this peculiar behaviour.
- split the pure perl backend into a loop module and an impl
module (AnyEvent::Loop and AnyEvent::Impl::Perl).
- some read types (regex, netstring, json, storable) could
errornously keep an AE::Handle object alive on their own
(reported by Mohammad Toossi).
- AnyEvent::Socket::resolve_sockaddr and all functions using it now
supports /etc/hosts overrides.
- add more workarounds around child watcher bugs in IO::Async
and (newly introduced) in POE.
- use glib child watchers and try to work around its limitations,
if possible (based on a patch by Kevin Ryde).
- add support for FLTK (fltk2), via AnyEvent::Impl::FLTK2.
- many read types in AnyEvent::Handle would malfunction during
transitions to TLS because of a "delete $self->{rbuf}".
(reported by Gerald Galster).
- improve condvar blocking wait performance (probably only noticable
with faster backends), also make it easier for event loops that
do not support blocking waits.
- PERL_ANYEVENT_MODEL now also allows full module names, although
the usefulness of this feature is not yet clear.
- add tests for all supported event loops, conditional on PERL_ANYEVENT_LOOP_TESTS.
- add t/80_ssltext.t.
- no longer use AUTOLOAD for the initial loading (for no very good reason).
- tcp_server now tries to unlink unix domain sockets when it gets destroyed.
- do not run event loop detection multiple times when programs call their cached
copies of AnyEvent::detect.
- parse_hostport now accepts absolute paths als unix domain sockets.
- suppress the idiotic warning inside POE by patching the POE::Kernel
run flags instead of asking the user to jump through contortions.
- add Task::Weaken as dependency (as recommends only at this time).
- replace PF_UNSPEC by 0, for good old minix.
6.0 (not officially released, but was on CPAN for about 15 minutes :/)
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.
- 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::run_cmd 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.
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.
- really replace longest run of :0: by :: in format_address,
also properly convert :: and ::1 again.
- 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.
- in the unlikely event of a virtual circuit connection
being invalidated by a delayed udp reply, AnyEvent::DNS
could die. this has been fixed.
- 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
in AnyEvent::Handle.
- 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 *_read_chunk, where the callback was called with $self as
first and second argument.
- simplified and fixed regex handling in AnyEvent::Handle::*_read_line.
- 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.
