	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).

)

Callers should use DuplicateJob::newFromJob() instead.

Parameters

Member Function Documentation

newFromJob()

static MediaWiki\JobQueue\Jobs\DuplicateJob::newFromJob ( RunnableJob $job )

static

Get a duplicate no-op version of a job.

Parameters

RunnableJob

$job

Returns

Job

Definition at line 51 of file DuplicateJob.php.

References $job.

run()

MediaWiki\JobQueue\Jobs\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 MediaWiki\JobQueue\RunnableJob.
