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
for no reason, too, but I didn't care for checking, it's too
depressing. This version only works around the WSAEWOULDBLOCK
issue, because I don't have a nice way to work around the
WSAEINPROGRESS bug.
7.08 Wed Dec 10 05:27:17 CET 2014
- work around a newly introduced bug in Socket 2.011 (an
errornous sun_length check) (analyzed by Maxime Soulé).
- AnyEvent::TLS didn't load (but refer to) AnyEvent::Socket
(analyzed by Ben Magistro).
- AnyEvent::Strict will now confess, not croak. This is in line with
it being a development/debugging tool.
- work around a number of libglib bugs (debug builds of libglib enforce
certain undocumented behaviour patterns such as not being able to
remove a child watch source after it has fired, which we will try
to emulate to avoid "criticals". what where they thinking...).
- mention json security issues in AnyEvent::Handle, now that Douglas
Crockford has foolishly and incompatibly changed JSON.
- changed default dns resolver "max_outstanding" value from 1 to 10,
the latter beinfg the intended value all along
(reported by Ilya Chesnokov).
- added new "AnyEvent::Impl::UV" interface module to the UV event lib
(written by Mike Lowell).
7.07 Tue Dec 17 17:45:02 CET 2013
- the documentation for custom tls verify schemes was wrong. make it agree
with the code (reported by Maxime Soulé).
- added cbor read and write types to AnyEvent::Handle (using CBOR::XS).
- work around an API change in openssl that could cause wrong tls connection
aborts, likely on windows only (analyzed by sten).
- calling AnyEvent->now_update with AnyEvent::Impl::Perl caused an
endless loop (reported by Dietrich Rebmann).
- add tlsv1_1 and tlsv1_2 protocols to AnyEvent::TLS
(patch by Maxime Soulé).
- document AnyEvent::Impl::IOAsync::set_loop and
$AnyEvent::Impl::IOAsync::LOOP. Though only documented now, this
functionality has _always_ been available.
- force a toplevel domain name in t/81_hosts.t (analyzed by
David Jack Wange Olrik).
- document that AnyEvent::Log uses AnyEvent::IO.
- warn about AnyEvent::Filesys::Notify performance.
- praise the joys of AnyEvent::Fork::*.
- time for an =encoding directive.
- do no longer use JSON to create a default json coder, use
JSON::XS or JSON::PP directly.
7.05 Wed Aug 21 10:38:08 CEST 2013
- uts46data.pl couldn't be found due to wrong naming of the file
(reported by Fulko Hew).
- handle lone \015's properly in AE::Handle's default line read
(reported by various people).
- untaint ip addresses found in /etc/hosts (patch by José Micó).
- the memleak fix in 7.03 caused resolving via /etc/hosts to always
fail on first use (reported and testcase by Andrew Whatson).
- expose AnyEvent::Log::format_time, and allow users to redefine it.
- expose AnyEvent::Log::default_format, and allow redefinition.
- expose AnyEvent::Log::fatal_exit, to allow redefinition.
- AnyEvent::Debug shell can now run coro shell commands, if available.
- t/63* tests were wrongly in MANIFEST.
- kernel.org's finger server went MIA, switch to freebsd.org and
icculus.org.
- clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO
to function asynchronously (reported by Daniel Carosone).
- hard-disable $^W in most tests, it generates too much garbage output.
- use a (hopefully) more future-proof method to emulate common::sense.
- upgrade to UTS-46:6.2.0.
- switch to INSTLIB from INSTLIBDIR, as INSTLIBDIR was wrongly
documented. should not affect anything.
7.04 Thu Nov 15 02:23:58 CET 2012
- debugging code left in.
7.03 Thu Nov 15 02:16:11 CET 2012
- AnyEvent::Socket::inet_aton did not work when dns resolution was
used to find the addresses (analyzed and patch by Maxime Soulé).
- fix a memory leak in the /etc/hosts lookup code when hosts don't
resolve and are not in hosts (analyzed by sten).
7.02 Tue Aug 14 04:27:58 CEST 2012
- AnyEvent::Util::run_cmd could block indefinitely (analyzed and test
program by Yorhel).
- verified that AnyEvent::Socket follows RFC5952.
- try to parse "ADDR#PORT" in addition to "ADDR PORT".
7.01 Sun May 13 01:03:17 CEST 2012
- fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but
not available, instead of throwing an exception.
- use File::Spec to get the tmpdir in t/*, to avoid needless
failures on (most, not mine :) windows boxes.
- new handle read types: tls_detect and tls_autostart.
7.0 Fri Apr 13 06:33:30 CEST 2012
- child watchers are broken in POE 1.352 (also many earlier
versions) and there seems to be no way to work around it, as POE
itself is inherently racy. Document this regression and add a delay
in t/68_poe_03_child.t for the time being.
- new module AnyEvent::IO, that is a frontend to either a pure-perl
synchronous I/O implementation (AnyEvent::IO::Perl), or to the
asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO).
- load /etc/hosts only when DNS has no answer.
- stat /etc/hosts on every access and reload it if it changed.
- load /etc/hosts via AnyEvent::IO - potentially asynchronous.
- fix a buggy croak in the dh parameter reading in AnyEvent::TLS.
- AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As
a side effect, they now use true appending as opposed to libc
appending, and the file might not have been opened when the function
returns.
- the default logging level was not properly documented in a variety of
places, this has hopefully been rectified.
- updated uts46data.pl for unicode 6.1.0.
- made log messages generated by AnyEvent submodules not
include the package name anymore, as it will be logged
by default already.
- upgrade to the trick used by common-sense 3.5 to work
around extra warning torture/breakage under perl 5.15.x.
- log messages by anyevent are now ucfirst, are usually full
sentences and do no longer include the package name.
- the storable read type would sometimes throw an exception instead
of causing EBADMSG (analyzed by Maxime Soulé).
- work around a bug in openssl 1.0.1 which enforces a minimum rsa
keysize (reported by Paul Howarth).
- documented Rocco fabricating statements about AnyEvent and me.
6.14 Tue Jan 31 20:00:24 CET 2012
- AnyEvent::Impl::Tk was broken due to a mysterious "die" inside,
probably an editing mistake (reported by Darin McBride).
6.13 Thu Jan 12 07:27:01 CET 2012
- AnyEvent::Util::fork_call checked for POSIX availability in the wrong way,
causing it to fail if POSIX wasn't loaded already (analysed by Rock Power).
- AnyEvent::Handle::push_read (line => did pass $1 directly, so
regex-matching inside the callback would change the parameter, despite
$1 being dynamically scoped per-block. this perl bug is now being
worked around (testcase by Cindy Wang).
6.12 Mon Dec 12 13:21:10 CET 2011
- $! was clobbered by subsequent calls in tcp_connect, due to
the postpone not saving/restoring it (analyzed by Richard Garnish).
6.11 Tue Nov 22 10:36:05 CET 2011
- Tk cannot create windows when tainted unless you set a title, so
set a dummy title for AnyEvent's dummy mainwindow. How dummy.
- escape any nonprintable/nonascii characters when stringifying
backtraces.
- log the reason loading an interface module fails to load at level debug.
6.1 Tue Oct 4 19:44:30 CEST 2011
- INCOMPATIBLE CHANGE: the default log level is now "4" (error
and above), and some messages inside AnyEvent have been elevated
to higher log levels to print by default.
- AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
- work around yet another signal race bug, newly introduced by POE. My
how that module sucks.
- add google public ipv6 dns as fallback servers, so AE::DNS can finally
support ipv6-only operation even with defaults (also use ::1 instead
of 127.0.0.1).
- give better guidelines on how to chose a logging level.
- AnyEvent::Log can now cap (limit) log message priority by context.
- AE::log will now save and restore $! and $@, so callers don't have to.
- AE::Strict now checks that registered fds are still valid at regular
intervals.
- skip frequently called 'require' calls if the module appears loaded.
- increase signal latency test timer considerably for poor little osx,
which can't be bothered with basic posix functionality such as signal
delivery.
- mention some debugging aids in the tutorial.
- new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
- private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
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.
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.
- 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::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
- 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
- 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.
( run in 1.506 second using v1.01-cache-2.11-cpan-e1769b4cff6 )
