A handle for managing updates for derived page data on edit, import, purge, etc.
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.
MCR migration note: this replaces the relevant methods in WikiPage, and covers the use cases of PreparedEdit.

| MediaWiki\Storage\DerivedPageDataUpdater::doUpdates | ( | ) |
Do standard updates after page edit, purge, or import.
Update links tables and other derived data. Purges pages that depend on this page when appropriate. With a 10% chance, triggers pruning the recent changes table.
Further updates may be triggered by core components and extensions that listen to the PageLatestRevisionChanged event. Search for method names starting with "handlePageLatestRevisionChangedEvent" to find listeners.

| MediaWiki\Storage\DerivedPageDataUpdater::prepareContent | ( | UserIdentity | $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.
| UserIdentity | $user | The user to act as context for pre-save transformation (PST). |
| RevisionSlotsUpdate | $slotsUpdate | The new content of the slots to be updated by this edit, before PST. |

| MediaWiki\Storage\DerivedPageDataUpdater::prepareUpdate | ( | RevisionRecord | $revision, |

Prepare derived data updates targeting the given RevisionRecord.
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.
