The RefreshLinksJob.php file contains the RefreshLinksJob class for jobs to update links for a given title.
These jobs use the class LinksUpdate to update several database tables.
Variants
The refreshLink jobs come in three different variants:
- Recursive jobs to update links for backlink pages for a given title. They are scheduled by LinksUpdate::queueRecursiveJobsForTable() and used to refresh pages which link / transclude a given title. These jobs have
(recursive:true,table:<table>)set. They just look up which pages link to the job title and schedule them as a set of non-recursive RefreshLinksJob jobs (and possibly, one new recursive job as a way of continuation). - Jobs to update links for a set of pages (the job title is ignored). These jobs have (pages:(<page ID>:(<namespace>,<title>),...) set.
- Jobs to update links for a single page (the job title). These jobs need no extra fields set.
Parameters
Job parameters for all jobs
recursive(bool): When false, updates the current page. When true, updates the pages which link/transclude the current page.triggeringRevisionId(int): The revision of the edit which caused the link refresh. For manually triggered updates, the last revision of the page (at the time of scheduling).triggeringUser(array): The user who triggered the refresh, in the form of a[ 'userId' => int, 'userName' => string ]array. This is not necessarily the user who created the revision.triggeredRecursive(bool): Set on all jobs which were partitioned from another, recursive job. Intended for debugging.
Standard deduplication params
See also JobQueue::deduplicateRootJob().
For recursive jobs :
table(string): Which table to use (imagelinks or templatelinks) when searching for affected pages.range(array): Used for recursive jobs when some pages have already been partitioned into separate jobs. Contains the list of ranges that still need to be partitioned. See BacklinkJobUtils::partitionBacklinkJob().division: Number of times the job was partitioned already (for debugging).
For non-recursive jobs :
pages(array): Associative array of[ <page ID> => [ <namespace>, <dbkey> ] ]. Might be omitted, then the job title will be used.isOpportunistic(bool): Set for opportunistic single-page updates. These are "free" updates that are queued when most of the work needed to be performed anyway for non-linkrefresh-related reasons, and can be more easily discarded if they don't seem useful. See WikiPage::triggerOpportunisticLinksUpdate().useRecursiveLinksUpdate(bool): When true, triggers recursive jobs for each page.
Metrics
refreshlinks_warning.<warning>: a recoverable issue. The job will continue as normal.refreshlinks_outcome.<reason>: if the job ends with an unusual outcome, it will increment this exactly once.- The reason starts with
bad_: a failure is logged and the job may be retried later. - The reason starts with
good_: the job was cancelled and considered a success, i.e. it was superseded.
- The reason starts with
