 __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

 getParams ()
 
Returns
array Parameters that specify sources, targets, and options for execution

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.

Detailed Description

Custom job to perform updates on tables in busier environments.

Job parameters include:

  • table : DB table to update
  • column : The *_user_text column to update
  • oldname : The old user name
  • newname : The new user name
  • count : The expected number of rows to update in this batch

Additionally, one of the following groups of parameters must be set: a) The timestamp based rename parameters:

  • timestampColumn : The *_timestamp column
  • minTimestamp : The minimum bound of the timestamp column range for this batch
  • maxTimestamp : The maximum bound of the timestamp column range for this batch
  • uniqueKey : A column that is unique (preferably the PRIMARY KEY) [optional] b) The unique key based rename parameters:
  • uniqueKey : A column that is unique (preferably the PRIMARY KEY)
  • keyId : A list of values for this column to determine rows to update for this batch

To avoid some race conditions, the following parameters should be set:

  • userID : The ID of the user to update
  • uidColumn : The *_user_id column

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\RenameUser\RenameUserJob::__construct ( Title $title,
$params,
Config $config,
ILBFactory $lbFactory )

Member Function Documentation

◆ run()

MediaWiki\RenameUser\RenameUserJob::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.
