Detailed Description

Job to update link tables for pages.

This job comes in a few variants:

a) Recursive jobs to update links for backlink pages for a given title. These jobs have (recursive:true,table:

set.
b) Jobs to update links for a set of pages (the job title is ignored). These jobs have (pages:(<page ID>:(<namespace>,<title>),...) set.
c) Jobs to update links for a single page (the job title) These jobs need no extra fields set.

◆ getCurrentRevisionIfUnchanged()

RefreshLinksJob::getCurrentRevisionIfUnchanged	(	WikiPage	$page,
		StatsdDataFactoryInterface	$stats
	)

private

Get the current revision record if it is unchanged from what was loaded in $page.

Parameters

WikiPage	$page	Page already loaded with READ_LATEST
StatsdDataFactoryInterface	$stats

Returns: RevisionRecord|null The same instance that $page->getRevisionRecord() uses

Definition at line 272 of file RefreshLinksJob.php.

References Job\$title, WikiPage\getId(), Title\getLatestRevID(), WikiPage\getRevisionRecord(), WikiPage\getTitle(), and Job\setLastError().

◆ getDataUpdateOptions()

RefreshLinksJob::getDataUpdateOptions ( )

private

Returns: array

◆ getDeduplicationInfo()

RefreshLinksJob::getDeduplicationInfo ( )

Subclasses may need to override this to make duplication detection work.

The resulting map conveys everything that makes the job unique. This is only checked if ignoreDuplicates() returns true, meaning that duplicate jobs are supposed to be ignored.

Returns: array Map of key/values

Since: 1.21

Reimplemented from Job.

Parameters
