Revision history for IO-Async
0.19 CHANGES:
* Allow control of Sequencer's pipelining
* Documentation fixes
* Allow Loop->run_child to take a 'setup' array
* Added 'setuid', 'setgid' and 'setgroups' child setup operations
* Support 'on_notifier' in Loop->listen
BUGFIXES:
* carp before return in Stream->write so it actually prints
* Ensure Streams still work after being closed and reopened by
->set_handle
* If IO::Socket->new() fails, try again with generic ->socket
(makes IPv6 work on platforms without IO::Socket::INET6)
0.18 CHANGES:
* Allow Sequencer to be a base class as well as using constructor
callbacks
* Use signal names from Config.pm rather than relying on POSIX.pm.
Covers more signals that way
BUGFIXES:
* Gracefully handle accept() returning EAGAIN
* Fixed handling of IO::Socket->getsockopt( SOL_SOCKET, SO_ERROR )
0.17 CHANGES:
* Added Stream->close_when_empty and ->close_now. Added docs
* Added OS abstractions of socketpair() and pipe()
* Many documentation changes and updates
BUGFIXES:
* Properly handle stream read/write errors; close immediately rather
than deferring until empty.
* Various CPAN testers somketest bug fixes
* Fixed http://rt.cpan.org/Ticket/Display.html?id=38476
0.16 ADDITIONS:
* Loop->requeue_timer()
* Magic constructor in IO::Async::Loop which tries to find the best
subclass
* 'chdir' and 'nice' ChildManager operations
CHANGES:
* Make sure that top-level objects are refcount-clean by using
Test::Refcount, and Scalar::Util::weaken()
BUGFIXES:
* Keep perl 5.6.1 happy by not passing LocalPort => 0 when
constructing IO::Socket::INETs
* Pass the Type option to IO::Socket::INET constructor in test
scripts
0.15 REMOVALS:
* IO::Async::Set subclasses and IO::Async::Buffer have now been
entirely removed.
CHANGES:
* Support handle-less IO::Async::Sequencer, like ::Notifier
* Set SO_REUSEADDR on listening sockets by default
* Allow Loop->listen() on a plain filehandle containing a socket
* No longer any need to explcitly call Loop->enable_childmanager
BUGFIXES:
* IO::Async::Loop->_adjust_timeout actually works properly
* Notifier->close() only runs on_closed callback if it actually
closed - allows for neater cross-connected Notifiers
* Made Notifier->want_{read,write}ready more efficient
* Notifier->close() on a child notifier works
* Loop->listen() should take the first successful address, rather
than trying them all
0.14 REMOVALS:
* IO::Async::Set subclasses and IO::Async::Buffer are now completely
deprecated. Any attempt to use them will fail immediately.
ADDITIONS:
* 'keep' ChildManager operation
* IO::Async::Test::wait_for_stream()
* Loop->listen()
* IO::Async::Sequencer class
CHANGES:
* Support dynamic swapping of temporary 'on_read' handlers in Stream
* Now requires Socket::GetAddrInfo >= 0.08
* Further shortcuts in ChildManager setup keys - IO references and
simple string operation names
* Support handle-less IO::Async::Notifiers that have IO handles added
to them later
* Allow 'setup' key to Loop->detach_code()
* Various documentation updates
BUGFIXES:
* Allow the same filehandle to be 'dup'ed more than once in
ChildManager
0.13 CHANGES:
* Flush all awaiting data from Stream when it becomes writeready
* Supply a real IO::Async::Test module to allow testing in 3rd party
distros
* Various documentation fixes
BUGFIXES:
* Don't rely on STDOUT being writable during test scripts
0.12 CHANGES:
* Allow Notifiers that are write-only.
* Added ChildManager->open and ->run; with ->open_child and
->run_child on the containing Loop.
* Moved IO::Async::Loop::Glib out to its own CPAN dist, to
simplify Build.PL and testing scripts
BUGFIXES:
* Make sure to "use IO::Socket" in IO::Async::Connector
* Pass 'socktype' argument to ->connect during testing
0.11 INCOMPATIBLE CHANGES:
* Renamed IO::Async::Set::* to IO::Async::Loop::* - provided
backward-compatibility wrappers around old names.
IO::Async::Set::GMainLoop has become IO::Async::Lib::Glib
* Renamed IO::Async::Buffer to IO::Async::Stream - provided backward-
compatibility wrapper around old name.
* Loop->get_childmanager() and ->get_sigproxy() no longer allowed
CHANGES:
* Extended ->loop_once() and ->loop() feature out to all
IO::Async::Loop classes
* Added IO::Async::Resolver and IO::Async::Connector, plus Loop
integration
* Allow write-only IO::Async::Notifiers that have no read handle or
readiness callback.
0.10 INCOMPATIBLE CHANGES:
* Renamed events and methods in IO::Async::Notifier to better fit the
naming scheme of normal Perl handles. Backward-compatibility hooks
are currently provided, but will be removed in a later release. Any
code using the old names should be updated
CHANGES:
* Allow DetachedCode to have multiple back-end worker processes.
* Control if a back-end worker exits when the code "die"s
* Added 'close()' method on Notifiers/Buffers. Sensible behaviour on
buffers with queued data to send
* Reset %SIG hash in ChildManager->detach_child()
BUGFIXES:
* Clean up temporary directory during testing
* Shut down DetachedCode workers properly on object deref
* Better handling of borderline timing failures in t/11set-*.t
* Close old handles before dup2()ing new ones when detaching code
* Various other minor test script improvements
0.09 CHANGES:
* Added TimeQueue object and integration with IO::Async::Set and
subclasses.
* Added MergePoint object
* Added 'on_closed' callback support to IO::Async::Notifier
BUGFIXES:
* Don't depend on system locale when checking string value of $!
* Fixed test scripts to more closely approximate real code behaviour
in the presence of poll() vs. deferred signal delivery
0.08 CHANGES:
* Added ChildManager->detach_child() method
* Added DetachedCode object
BUGFIXES:
* Better tests for presence of Glib to improve test false failures
* More lenient times in test script 11set-IO-Poll-timing to allow for
variances at test time
* Avoid bugs in post_select()/post_poll() caused by some notifier
callbacks removing other notifiers from the set
0.07 BUGFIXES:
* Avoid race condition in t/30childmanager.t - wait for child process
to actually exit
* Avoid race condition in IO::Async::ChildManager->spawn() by waiting
for SIGCHLD+pipe close, rather than SIGCHLD+pipe data
0.06 CHANGES:
* Allow 'env' setup key to ChildManager->spawn() to change the
child's %ENV
* Updated the way some of the ->spawn() tests are conducted. There
seems to be massive failures reported on cpantesters against 0.05.
These changes won't fix the bugs, but should assist in reporting
and tracking them down.
BUGFIXES:
* Don't rely on existence of /bin/true - test for /usr/bin/true as
well, fall back on "$^X -e 1"
* Avoid kernel race condition in t/32childmanager-spawn-setup.t by
proper use of select() when testing.
0.05 CHANGES:
* Added ChildManager object
* Added singleton storage in IO::Async::Set to store a SignalProxy or
ChildManager conveniently
BUGFIXES:
* Workaround for a bug in IO::Poll version 0.05
0.04 CHANGES:
* Added dynamic signal attach / detach methods to SignalProxy
* Buffer now has on_read_error / on_write_error callbacks for
handling IO errors on underlying sysread()/syswrite() calls
0.03 CHANGES:
* No longer build_requires 'Glib' - print a warning if it's not
installed but carry on anyway.
* IO_Poll->loop_once() now returns the result from the poll() call
* Added concept of nested child notifiers within Notifier object
BUGFIXES:
* Fix to test scripts that call IO_Poll's loop_once() with a timeout
of zero. This can cause a kernel race condition, so supply some
small non-zero value instead.
0.02 INCOMPATIBLE CHANGES:
* Event methods/callback functions now called "on_*" to distinguish
them
* Callback functions now pass $self as first argument to simplify
called code
CHANGES:
* Improved POD in Notifier.pm and Buffer.pm
BUGFIXES:
* GMainLoop.pm - return 1 from callbacks so that glib doesn't remove
our IO sources
* GMainLoop.pm - make sure re-asserting want_writeready actually adds
the IO source again
0.01 First version, released on an unsuspecting world.
