Hello,
I need some help about the interaction when Mojolicious and Minion working
together.
I have the full Mojolicious code where I load the Minion as a plugin and
using Pg as a backend.
sub status {
my $c = shift;
$c->render(json => $c->app->minion->stats, status => 200 );
return;
}
This is showing me the following output when the worker is not running:
{"active_jobs":0,"active_workers":0,"delayed_jobs":0,"enqueued_jobs":43,"failed_jobs":0,"finished_jobs":0,"inactive_jobs":7,"inactive_workers":0}
After I start the minion worker in a different terminal on the same host
and code:
{"active_jobs":0,"active_workers":0,"delayed_jobs":0,"enqueued_jobs":43,"failed_jobs":0,"finished_jobs":0,"inactive_jobs":7,"inactive_workers":1}
Inactive worker number increases as expected.
I am planning to use the following endpoint to post a costly long running
background job:
sub rescan {
my $c = shift;
my $minion = $c->app->minion;
$minion->add_task( 'rescan' => sub{
my $job = shift;
$job->app->SCSICleanup($job);
});
$minion->enqueue('rescan');
$c->render(json => {Service => 'Rescan'}, status => 200 );
return;
}
After I called the rescan function I have the following job in the
database: (select * from minion_jobs order by id desc limit 1 ;)
44;"[]";"2017-06-02 16:58:52.252232+01";"2017-06-02
16:58:52.252232+01";"";0;"";"";0;"";"inactive";"rescan";;"default";1;"{}"
The job remain inactive even if the worker is running.
In the development.log I have the following - worker restarted after code
changes:

I tried the following modification:
sub rescan {
my $c = shift;
my $minion = $c->app->minion;
$minion->add_task( 'rescan' => sub{
my $job = shift;
$job->app->SCSICleanup($job);
});
my id = $minion->enqueue('rescan');
$minion->job($id)->start;
$c->render(json => {Service => 'Rescan'}, status => 200 );
return;
}
After the modification the situation is exactly the same:
45;"[]";"2017-06-02 17:04:12.067348+01";"2017-06-02
17:04:12.067348+01";"";0;"";"";0;"";"inactive";"rescan";;"default";1;"{}"
Could you please help me what I am doing wrong or what I missed ?
Regards,
Arpad
