	__construct ( $command, $params=null)
	allowRetries ()
	Whether to retry execution of this job if run() returned false or threw an exception. Warning In some setups (i.e. when using change-propagation) jobs may still be retried even when this is false if the job fails due to a timeout unless it is also configured in change-prop config (T358939). Returns bool Whether this job can be retried on failure by job runners Since 1.21
	getDeduplicationInfo ()
	Subclasses may need to override this to make duplication detection work.
	getLastError ()
	Returns string
	getMetadata ( $field=null)
	getParams ()
	Returns array Parameters that specify sources, targets, and options for execution
	getQueuedTimestamp ()
	getReadyTimestamp ()
	Returns int|null UNIX timestamp of when the job was runnable, or null Since 1.26
	getReleaseTimestamp ()
	getRequestId ()
	Returns string|null Id of the request that created this job. Follows jobs recursively, allowing to track the id of the request that started a job when jobs insert jobs which insert other jobs. Since 1.27

run()

DuplicateJob::run

(

)

Run the job.

If this method returns false or completes exceptionally, the job runner will retry executing this job unless the number of retries has exceeded its configured retry limit. Retries are allowed by default, unless allowRetries() is overridden to disable retries.

See the architecture doc for more information.

Returns

bool Return false to instruct the job runner to retry a failed job. Otherwise return true to indicate that a job completed (i.e. succeeded, or failed in a way that's deterministic or redundant).

Implements RunnableJob.
