Hi Monks,

I have list of async jobs that need to happen one after the other. I can do that as per example below. However it has a deep recursion problem that limits the size of the queue. Also it has to store all the async instances (in this example in @times) which is silly as only 1 is really active at a time.

What would be the correct way to do this without recurssion?

Thanks!

use AnyEvent;

my @queue = (9,8,7,6,5,4,3,2,1);
my @timers;

my $cv = AnyEvent->condvar;

DoQueue();

# Do other things here...

$cv->recv;

sub DoQueue
{
    my $i = pop @queue;
    
    if (!defined $i)
    {
        $cv->send;
        return;
    }

    print "Starting async operation $i\n";
    $timers[$i] = AnyEvent->timer(after => 1, interval => 0, cb => sub
+ {
        print "Finish async operation $i\n";
        DoQueue();
    });
}
