=head2 clear

This clears the C<< job_picked_up_by >> value for the given job.

Parameters;

=head3 job_uuid (required)

This is the C<< job_uuid >> of the job to clear.

	}
	
	$job_uuid = $anvil->Job->update_progress({
		debug    => $debug,
		file     => $THIS_FILE, 
		line     => __LINE__, 
		progress => 0, 
		message  => "clear",
		job_uuid => $job_uuid,
	});
	$anvil->Log->variables({source => $THIS_FILE, line => __LINE__, level => 2, list => { job_uuid => $job_uuid }});
	
	return(0);
}

=head2 get_job_details

This takes a C<< job_uuid >> and returns the job's details. If the job is found, C<< 0 >> is returned. If it isn't found, C<< 1 >> is returned. If it is found, but C<< check >> was set and the process is still alive, C<< 2 >> is returned.

When successful, the job details will be stored in;

* C<< jobs::job_uuid >>
* C<< jobs::job_host_uuid >>
* C<< jobs::job_command >>
* C<< jobs::job_data >>
* C<< jobs::job_updated >>
* C<< jobs::job_picked_up_by >>
* C<< jobs::job_picked_up_at >>
* C<< jobs::job_name >>
* C<< jobs::job_progress >>
* C<< jobs::job_title >>
* C<< jobs::job_description >>
* C<< jobs::job_status >>

Parameters;

=head3 check (optional, default '1')

This checks to see if the job was picked up by a program that is still running. If set to C<< 1 >> and that process is running, this method will return C<< 2 >>. If set to C<< 0 >>, the job data will be loaded (if found) and C<< 0 >> will be returned.

=head3 job_uuid (optional)

This is the job UUID to pull up. If not passed, first a check is made to see if C<< --job-uuid >> was passed. If not, a check is made in the database for any pending jobs assigned to this host and whose C<< job_command >> matches the calling program.

=head2 get_job_uuid

This takes the name of a program and looks in jobs for a pending job with the same command. If it is found, C<< jobs::job_uuid >> is set and the C<< job_uuid >> is returned. If no job is found, and empty string is returned.

Parameters;

=head3 host_uuid (optional, default Get->host_uuid())

If set, this will search for the job on a specific host.

=head3 program (required)

This is the program name to look for. Specifically, this string is used to search C<< job_command >> (anchored to the start of the column and a wild-card end, ie: C<< program => foo >> would find C<< foobar >> or C<< foo --bar >>). Be as specific as possible. If two or more results are found, no C<< job_uuid >> will be returned. There must be only one match for this method to work properly.

=head2 update_progress

This updates the progress if we were called with a job UUID.

This also sets C<< sys::last_update >>, allowing you to see how long it's been since the progress was last updated and trigger an update on a time based counter.

Returns C<< 0 >> on success, C<< 1 >> on failure.

B<< Note >>: Some special C<< job_status >> processing is done to support some specific callers. These should not impact generic calls of this method.

Parameters;

=head3 job_uuid (optional, default 'jobs::job_uuid')

This is the UUID of the job to update. If it isn't set, but C<< jobs::job_uuid >> is set, it will be used. If that is also not set, 

=head3 message (optional)

If set, this message will be appended to C<< job_status >>. If set to 'C<< clear >>', previous records will be removed.

NOTE: This is in the format C<< <key>[,!!<variable_name1>!<variable_value1>[,...,!!<variable_nameN>!<variable_valueN>!!]] >>. Example; C<< foo_0001 >> or C<< foo_0002,!!bar!baz!! >>.

=head3 picked_up_by (optional, default '$$' (caller's PID))

If set, this is used for the C<< job_picked_up_by >> column. If it isn't set, the process ID of the caller is used.

=head3 progress (required)

This is a number to set the current progress to.
