AnyEvent::AggressiveIdle(3pm) User Contributed Perl Documentation AnyEvent::AggressiveIdle(3pm)
NAME
AnyEvent::AggressiveIdle - Aggressive idle processes for AnyEvent.
SYNOPSIS
use AnyEvent::AggressiveIdle qw(aggressive_idle};
aggressive_idle {
... do something important
};
my $idle;
$idle = aggressive_idle {
... do something important
if (FINISH) {
undef $idle; # do not call the sub anymore
}
};
DESCRIPTION
Sometimes You need to do something that takes much time but can be split into elementary phases. If You use AE::idle and Your program is a
highload project, idle process can be delayed for much time (second, hour, day, etc). aggressive_idle will be called for each AnyEvent loop
cycle. So You can be sure that Your idle process will continue.
EXPORTS
aggressive_idle
Register Your function as aggressive idle watcher. If it is called in VOID context, the watcher wont be deinstalled. Be carrefully.
In NON_VOID context the function returns a guard. Hold the guard until You want to cancel idle process.
stop_aggressive_idle
You can use the function to stop idle process. The function receives idle process PID that can be received in idle callback (the first
argument).
Example:
use AnyEvent::AggressiveIdle ':all'; # or:
use AnyEvent::AggressiveIdle qw(aggressive_idle stop_aggressive_idle);
aggressive_idle {
my ($pid) = @_;
....
stop_aggressive_idle $pid;
}
The function will throw an exception if invalid PID is received.
Continuous process.
Sometimes You need to to something continuous inside idle callback. If You want to stop idle calls until You have done Your work, You can
hold guard inside Your process:
aggressive_idle {
my ($pid, $guard) = @_;
my $timer;
$timer = AE::timer 0.5, 0 => sub {
undef $timer;
undef $guard; # POINT 1
}
}
Until 'POINT 1' aggressive_idle won't call its callback. Feel free to stop_aggressive_idle before free the guard.
