<p><i> I try to implement the Thread::Queue module, but the provided example and the other resources I have been reading only consider a defined amount of queued tasks (when this may vary in my case). </i>
<P> What does that mean?
<p> Its unclear what your diagram looks like, but I think Thread::Queue is workable like this <c>
#!/usr/bin/perl --
use strict; use warnings;
use threads stack_size => 4096;
use Thread::Queue;
my %serverQ;
my $resultQ = Thread::Queue->new;
my @workers = map {
my $workQ = Thread::Queue->new;
threads->create( \&Worker, $workQ, $resultQ );
} 1..10;
...
while( @targets ){
...
if( my $q = $serverQ{ $host } ){
$q->enqueue( [
## 'Foo::bar::deployRoutine', $onearg, $twoarg, $threearg ,
'deployRoutine' =>
$targetServer, $deploySource, $deployDest, "true",
] );
...
FreeFreeWorkers( \%serverQ ); ## check empty Qs, unassociate from a host
...
$_->join for threads->list;
exit( 0 );
sub Worker {
my( $workQ, $resultQ ) = @_;
while( defined( my $jobDesc = $workQ->dequeue ) ) {
my( $package, $function, @args ) = @$jobDesc;
require Module::Load;
Module::Load::load( $package );
$resultQ->enqueue( [ $function->( @args ) ] );
}
return;
}
</c>
