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. - - new function: AnyEvent::postpone. + - *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 (currently third-party) AnyEvent::Impl::FLTK. + - 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). - - resolve AnyEvent::Util::guard at first-use-time, not at load time, - for further speed and memory savings when not used. - 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,
