NAME AnyEvent::DBus - adapt Net::DBus to AnyEvent SYNOPSIS use AnyEvent::DBus; # now use the Net::DBus API, preferably the non-blocking variants: use Net::DBus::Annotation qw(:call); $bus->get_object (...) ->Method (dbus_call_async, $arg1, ...) ->set_notify (sub { my @data = $_[0]->get_result ... }); $bus->get_connection->send (...); DESCRIPTION This module is an AnyEvent user, you need to make sure that you use and run a supported event loop. Loading this module will install the necessary magic to seamlessly integrate Net::DBus into AnyEvent. It does this by quite brutally hacking Net::DBus::Reactor so that all dbus connections created after loading this module will automatically be managed by this module. Note that a) a lot inside Net::DBus is still blocking b) if you call a method that blocks, you again block your process (basically anything but calls to the Net::DBus::Binding::Connection objects block, but see Net::DBus::Annoation, specifically dbus_call_async) c) the underlying libdbus is often blocking itself, even with infinite timeouts and d) this module only implements the minimum API required to make Net::DBus work - Net::DBus unfortunately has no nice hooking API. However, unlike Net::DBus::Reactor, this module should be fully non-blocking as long as you only use non-blocking APIs (Net::DBus::Reactor blocks on writes). It should also be faster, but Net::DBus is such a morass so unneeded method calls that speed won't matter much... EXAMPLE Here is a simple example. Both work with AnyEvent::DBus and do the same thing, but only the second is actually non-blocking. Example 1: list registered named, blocking version. use AnyEvent::DBus; my $conn = Net::DBus->find; my $bus = $conn->get_bus_object; for my $name (@{ $bus->ListNames }) { print " $name\n"; } Example 1: list registered named, somewhat non-blocking version. use AnyEvent; use AnyEvent::DBus; use Net::DBus::Annotation qw(:call); my $conn = Net::DBus->find; # always blocks :/ my $bus = $conn->get_bus_object; my $quit = AE::cv; # the trick here is to prepend dbus_call_async to any method # arguments and then to call the set_notify method on the # returned Net::DBus::AsyncReply object $bus->ListNames (dbus_call_async)->set_notify (sub { for my $name (@{ $_[0]->get_result }) { print " $name\n"; } $quit->send; }); $quit->recv; SEE ALSO AnyEvent, Net::DBus.
