Detailed Description

A handle for managing updates for derived page data on edit, import, purge, etc.

Note
Avoid direct usage of DerivedPageDataUpdater.
Todo:
Define interfaces for the different use cases of DerivedPageDataUpdater, particularly providing access to post-PST content and ParserOutput to callbacks during revision creation, which currently use WikiPage::prepareContentForEdit, and allowing updates to be triggered on purge, import, and undeletion, which currently use WikiPage::doEditUpdates() and Content::getSecondaryDataUpdates().

DerivedPageDataUpdater instances are designed to be cached inside a WikiPage instance, and re-used by callback code over the course of an update operation. It's a stepping stone on the way to a more complete refactoring of WikiPage.

When using a DerivedPageDataUpdater, the following life cycle must be observed: grabCurrentRevision (optional), prepareContent (optional), prepareUpdate (required for doUpdates). getCanonicalParserOutput, getSlots, and getSecondaryDataUpdates require prepareContent or prepareUpdate to have been called first, to initialize the DerivedPageDataUpdater.

See also
docs/pageupdater.md for more information.

MCR migration note: this replaces the relevant methods in WikiPage, and covers the use cases of PreparedEdit.

Other aspects of a MutableRevisionRecord returned from here, such as the user or the comment, may be changed, but may not be reflected in ParserOutput until after prepareUpdate() has been called.
Todo:
This is currently used by PageUpdater::makeNewRevision() to construct an unsaved MutableRevisionRecord instance. Introduce something like an UnsavedRevisionFactory service for that purpose instead!

◆ getWikiPage()

MediaWiki\Storage\DerivedPageDataUpdater::getWikiPage ( )
private

◆ grabCurrentRevision()

MediaWiki\Storage\DerivedPageDataUpdater::grabCurrentRevision ( )

Returns the revision that was the page's current revision when grabCurrentRevision() was first called.

During an edit, that revision will act as the logical parent of the new revision.

Some updates are performed based on the difference between the database state at the moment this method is first called, and the state after the edit.

See also
docs/pageupdater.md for more information on when thie method can and should be called.
Note
After prepareUpdate() was called, grabCurrentRevision() will throw an exception to avoid confusion, since the page's current revision is then the new revision after the edit, which was presumably passed to prepareUpdate() as the $revision parameter. Use getParentRevision() instead to access the revision that is the parent of the new revision.
Returns
RevisionRecord|null the page's current revision, or null if the page does not yet exist.

◆ isChange()

MediaWiki\Storage\DerivedPageDataUpdater::isChange ( )

Whether the edit created, or should create, a new revision (that is, it's not a null-edit).

Warning
at present, "null-revisions" that do not change content but do have a revision record would return false after prepareContent(), but true after prepareUpdate()! This should probably be fixed.
Returns
bool

UserIdentity | null$userThe user creating the revision in question
RevisionRecord | null$revisionNew revision (after save, if already saved)
RevisionSlotsUpdate | null$slotsUpdateNew content (before PST)
null | int$parentIdParent revision of the edit (use 0 for page creation)

References MediaWiki\Storage\DerivedPageDataUpdater\assertHasPageState().

◆ prepareContent()

MediaWiki\Storage\DerivedPageDataUpdater::prepareContent ( User  $user,
RevisionSlotsUpdate  $slotsUpdate,
  $useStash = true 
)

Prepare updates based on an update which has not yet been saved.

This may be used to create derived data that is needed when creating a new revision; particularly, this makes available the slots of the new revision via the getSlots() method, after applying PST and slot inheritance.

The derived data prepared for revision creation may then later be re-used by doUpdates(), without the need to re-calculate.

See also
docs/pageupdater.md for more information on when thie method can and should be called.
Note
Calling this method more than once with the same $slotsUpdate has no effect. Calling this method multiple times with different content will cause an exception.
Calling this method after prepareUpdate() has been called will cause an exception.
Parameters
User$userThe user to act as context for pre-save transformation (PST). Type hint should be reduced to UserIdentity at some point.
RevisionSlotsUpdate$slotsUpdateThe new content of the slots to be updated by this edit, before PST.
bool$useStashWhether to use stashed ParserOutput

◆ prepareUpdate()

MediaWiki\Storage\DerivedPageDataUpdater::prepareUpdate ( RevisionRecord  $revision,
array  $options = [] 
)

Prepare derived data updates targeting the given Revision.

Calling this method requires the given revision to be present in the database. This may be right after a new revision has been created, or when re-generating derived data e.g. in ApiPurge, RefreshLinksJob, and the refreshLinks script.

See also
docs/pageupdater.md for more information on when thie method can and should be called.
Note
Calling this method more than once with the same revision has no effect. $options are only used for the first call. Calling this method multiple times with different revisions will cause an exception.
If grabCurrentRevision() (or prepareContent()) has been called before calling this method, $revision->getParentRevision() has to refer to the revision that was the current revision at the time grabCurrentRevision() was called.
Parameters
RevisionRecord$revision
array$optionsArray of options, following indexes are used:
  • changed: bool, whether the revision changed the content (default true)
  • created: bool, whether the revision created the page (default false)
  • moved: bool, whether the page was moved (default false)
  • restored: bool, whether the page was undeleted (default false)
  • oldrevision: RevisionRecord object for the pre-update revision (default null) can also be a Revision object, which is deprecated since 1.35
  • triggeringUser: The user triggering the update (UserIdentity, defaults to the user who created the revision)
  • oldredirect: bool, null, or string 'no-change' (default null):
    • bool: whether the page was counted as a redirect before that revision, only used in changed is true and created is false
    • null or 'no-change': don't update the redirect status.
  • oldcountable: bool, null, or string 'no-change' (default null):
    • bool: whether the page was counted as an article before that revision, only used in changed is true and created is false
    • null: if created is false, don't update the article count; if created is true, do update the article count
    • 'no-change': don't update the article count, ever When set to null, pageState['oldCountable'] will be used instead if available.
  • causeAction: an arbitrary string identifying the reason for the update. See DataUpdate::getCauseAction(). (default 'unknown')
  • causeAgent: name of the user who caused the update. See DataUpdate::getCauseAgent(). (string, default 'unknown')
  • known-revision-output: a combined canonical ParserOutput for the revision, perhaps from some cache. The caller is responsible for ensuring that the ParserOutput indeed matched the $rev and $options. This mechanism is intended as a temporary stop-gap, for the time until caches have been changed to store RenderedRevision states instead of ParserOutput objects. (default: null) (since 1.33)

◆ $pageState

array MediaWiki\Storage\DerivedPageDataUpdater::$pageState = null
private

The state of the relevant row in page table before the edit.

This is determined by the first call to grabCurrentRevision, prepareContent, or prepareUpdate (so it is only accessible in 'knows-current' or a later stage). If pageState was not initialized when prepareUpdate() is called, prepareUpdate() will attempt to emulate the state of the page table before the edit.

Contains the following fields:

  • oldRevision (RevisionRecord|null): the revision that was current before the change associated with this update. Might not be set, use getParentRevision().
  • oldId (int|null): the id of the above revision. 0 if there is no such revision (the change was about creating a new page); null if not known (that should not happen).
  • oldIsRedirect (bool|null): whether the page was a redirect before the change. Lazy-loaded, can be null; use wasRedirect() instead of direct access.
  • oldCountable (bool|null): whether the page was countable before the change (or null if we don't have that information)
