Hi,

i was trying http://gearman.org and i've therefor got from cpan Gearman::Client and Gearman::Client::Async but, for what i need, i felt like they weren't designed as i need, and i've tried to write another which suits best my needs.

Having not wrote any documentation, i'll just show you the usage:

use Gearman::OO::Client;

my $client = Gearman::OO::Client->new(
        servers => ['127.0.0.1:4730'],
        max_queue => 4,
);

logit("connected");
foreach my $id (1..8) {
        $client->submit(
                func=>'test',
                req=>"Data for $id",
                complete => sub { logit("completed #$id: @_"); },
                error => sub { logit("ERROR #$id! @_"); },
        );
        logit("added #$id");
}

logit("sync...");
$client->sync();
logit("done.");

and here the output with 2 workers which just sleep for 1 second and respond with an empty string1: 
00:00:00 connected
00:00:00 added #1
00:00:00 added #2
00:00:00 added #3
00:00:00 added #4
00:00:01 completed #1:
00:00:01 completed #2:
00:00:01 added #5
00:00:01 added #6
00:00:02 completed #3:
00:00:02 completed #4:
00:00:02 added #7
00:00:02 added #8
00:00:02 sync...
00:00:03 completed #5:
00:00:03 completed #6:
00:00:04 completed #7:
00:00:04 completed #8:
00:00:04 done.

As you can see, some jobs are added early up to the max_queue limit, then it will block until any of the previous job complete to continue.

Also you can use a completely OO Job object: 

package MyJob;
use base 'Gearman::OO::Job';

sub new { my ($class, %args) = @_; bless \%args, $class; }
sub function { 'test'; }
sub complete { my ($self, $data) = @_; logit("$self completed($data)")
+; }
sub req_data { my ($self) = @_; return $self->{req}; }

use Gearman::OO::Client;

my $client = Gearman::OO::Client->new(
        servers => ['127.0.0.1:4730'],
        max_queue => 4,
);

logit("connected");
foreach my $id (1..8) {
        $client->submit_job(MyJob->new(req => "OO #$id"));
        logit("added #$id");
}

logit("sync...");
$client->sync();
logit("done.");

and now the meditation: anyone think this could be usefull? and if so, which name should i use? does it merit to be on CPAN?
1 -- on twp distinct shells: gearman -w -f test sleep 1
