DESCRIPTION
This class manages publishing jobs. A publishing job designates that a given Story or Media object will be published by a Burner at a given time. Publishing jobs create distribution jobs as they are run. Jobs which fail in execution are tried again, and eventually if the failure continues marked as 'failed'.

  Public Instance Methods
################################################################################

$self = $job->execute_me

Executes the job. This sends the Story or Media object contained by the job to the burner. In case of a template error the job is released to be executed again. Three such errors are considered a failure, in which case the job is marked as such. The most recent error message is stored in the error_message field. At the end of the process, a completion time will be saved to the database. Attempting to execute a job before its scheduled time will throw an exception.

Throws: Quite a few exceptions can be thrown here. Check the do_it() methods on all Bric::Publish::Action subclasses, as well as the put_res() methods of the mover classes (e.g., Bric::Util::Trans::FS). Here are the exceptions thrown from withing this method itself.

•   Cannot execute job before its scheduled time.

•   Cannot execute job that has already been executed.

•   Can't get a lock on job.

•   Unable to connect to database.

•   Unable to prepare SQL statement.

•   Unable to execute SQL statement.

•   Incorrect number of args to Bric::_set().

•   Bric::set() - Problems setting fields.

Side Effects: NONE.

Notes: NONE.
