Detailed Description

Service for looking up page revisions.

Since: 1.31; 1.32 Renamed from MediaWiki\Storage\RevisionStore

Note: This was written to act as a drop-in replacement for the corresponding static methods in Revision.

Definition at line 79 of file RevisionStore.php.

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Revision\RevisionStore::__construct	(	ILoadBalancer	$loadBalancer,
		SqlBlobStore	$blobStore,
		WANObjectCache	$cache,
		CommentStore	$commentStore,
		NameTableStore	$contentModelStore,
		NameTableStore	$slotRoleStore,
		SlotRoleRegistry	$slotRoleRegistry,
		ActorMigration	$actorMigration,
		IContentHandlerFactory	$contentHandlerFactory,
		HookContainer	$hookContainer,
			$dbDomain = `false`
	)

Todo:: $blobStore should be allowed to be any BlobStore!

Parameters

ILoadBalancer	$loadBalancer
SqlBlobStore	$blobStore
WANObjectCache	$cache	A cache for caching revision rows. This can be the local wiki's default instance even if $dbDomain refers to a different wiki, since makeGlobalKey() is used to constructed a key that allows cached revision rows from the same database to be re-used between wikis. For example, enwiki and frwiki will use the same cache keys for revision rows from the wikidatawiki database, regardless of the cache's default key space.

NameTableStore	$slotRoleStore
SlotRoleRegistry	$slotRoleRegistry
ActorMigration	$actorMigration

◆ getContentBlobsForBatch()

MediaWiki\Revision\RevisionStore::getContentBlobsForBatch	(	$rowsOrIds,
		$slots = `null`,
		$queryFlags = `0`
	)

Gets raw (serialized) content blobs for the given set of revisions.

Callers are responsible for unserializing and interpreting the content blobs based on the model_name field and the slot role.

This method is intended for bulk operations in maintenance scripts. It may be chosen over newRevisionsFromBatch by code that are only interested in raw content, as opposed to meta data. Code that needs to access meta data of revisions, slots, or content objects should use newRevisionsFromBatch() instead.

Parameters

Traversable \| array	$rowsOrIds	list of revision ids, or revision rows from a db query.
array \| null	$slots	the role names for which to get slots.
int	$queryFlags

Returns

StatusValue a status containing, if isOK() returns true, a two-level nested associative array, mapping from revision ID to an associative array that maps from role name to an anonymous object object containing two fields:

model_name: the name of the content's model
blob_data: serialized content data

int	$queryFlags

Returns: StatusValue a status containing, if isOK() returns true, a two-level nested associative array, mapping from revision ID to an associative array that maps from role name to a database row object.

Create a new null-revision for insertion into a page's history.

This will not re-save the text, but simply refer to the text from the previous version.

Such revisions can for instance identify page rename operations and other such meta-modifications.

IResultWrapper \| \\stdClass[]	$rows	the rows to construct revision records from
array	$options	Supports the following options: 'slots' - whether metadata about revision slots should be loaded immediately. Supports falsy or truthy value as well as an explicit list of slot role names. The main slot will always be loaded. 'content' - whether the actual content of the slots should be preloaded. 'archive' - whether the rows where generated using getArchiveQueryInfo(), rather than getQueryInfo.
int	$queryFlags
Title \| null	$title	The title to which all the revision rows belong, if there is such a title and the caller has it handy, so we don't have to look it up again. If this parameter is given and any of the rows has a rev_page_id that is different from $title->getArticleID(), an InvalidArgumentException is thrown.

Returns: StatusValue a status with a RevisionRecord[] of successfully fetched revisions and an array of errors for the revisions failed to fetch.

◆ newRevisionSlots()

MediaWiki\Revision\RevisionStore::newRevisionSlots	(		$revId,
			$revisionRow,
			$slotRows,
			$queryFlags,
		Title	$title
	)

private

Factory method for RevisionSlots based on a revision ID.

Note: If other code has a need to construct RevisionSlots objects, this should be made public, since RevisionSlots instances should not be constructed directly.

Parameters

int	$revId
\\stdClass	$revisionRow
\\stdClass[] \| null	$slotRows
int	$queryFlags
Title	$title

Returns: RevisionSlots

Exceptions

MWException

◆ userWasLastToEdit()

MediaWiki\Revision\RevisionStore::userWasLastToEdit	(	IDatabase	$db,
			$pageId,
			$userId,
			$since
	)

Check if no edits were made by other users since the time a user started editing the page.

Limit to 50 revisions for the sake of performance.

MCR migration note: this replaces Revision::userWasLastToEdit

Deprecated:: since 1.31; Can possibly be removed, since the self-conflict suppression logic in EditPage that uses this seems conceptually dubious. Revision::userWasLastToEdit has been deprecated since 1.24.

Parameters

IDatabase	$db	The Database to perform the check on.
int	$pageId	The ID of the page in question
int	$userId	The ID of the user in question
string	$since	Look at edits since this time

Returns: bool True if the given user was the only one to edit since the given timestamp
