Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Revision\RevisionStore::__construct	(	ILoadBalancer	$loadBalancer,
		SqlBlobStore	$blobStore,
		WANObjectCache	$cache,
		BagOStuff	$localCache,
		CommentStore	$commentStore,
		NameTableStore	$contentModelStore,
		NameTableStore	$slotRoleStore,
		SlotRoleRegistry	$slotRoleRegistry,

		ActorStore	$actorStore,
		IContentHandlerFactory	$contentHandlerFactory,
		PageStore	$pageStore,
		TitleFactory	$titleFactory,
		HookContainer	$hookContainer,
			$wikiId = WikiAwareEntity::LOCAL )

Parameters

ILoadBalancer	$loadBalancer
SqlBlobStore	$blobStore
WANObjectCache	$cache	A cache for caching revision rows. This can be the local wiki's default instance even if $wikiId 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.
BagOStuff	$localCache	Another layer of cache, best to use APCu here.
CommentStore	$commentStore
NameTableStore	$contentModelStore
NameTableStore	$slotRoleStore
SlotRoleRegistry	$slotRoleRegistry
ActorMigration	$actorMigration
ActorStore	$actorStore
IContentHandlerFactory	$contentHandlerFactory
PageStore	$pageStore
TitleFactory	$titleFactory
HookContainer	$hookContainer
false \| string	$wikiId	Relevant wiki id or WikiAwareEntity::LOCAL for the current one

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

◆ 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 containing two fields:

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

Definition at line 2250 of file RevisionStore.php.

◆ getKnownCurrentRevision()

MediaWiki\Revision\RevisionStore::getKnownCurrentRevision	(	PageIdentity	$page,
			$revId = 0 )

Load a revision based on a known page ID and current revision ID from the DB.

This method allows for the use of caching, though accessing anything that normally requires permission checks (aside from the text) will trigger a small DB lookup.

MCR migration note: this replaced Revision::newKnownCurrent

Parameters

PageIdentity	$page	the associated page
int	$revId	current revision of this page. Defaults to $title->getLatestRevID().

Returns: RevisionRecord|bool Returns false if missing

Note: This method grabs a FOR UPDATE lock on the relevant row of the page table, to prevent a new revision from being inserted before the null revision has been written to the database.

MCR migration note: this replaced Revision::newNullRevision

Todo: Introduce newFromParentRevision(). newNullRevision can then be based on that (or go away).

Parameters

IDatabase	$dbw	used for obtaining the lock on the page table row
PageIdentity	$page	the page to read from
CommentStoreComment	$comment	RevisionRecord's summary
bool	$minor	Whether the revision should be considered as minor
UserIdentity	$user	The user to attribute the revision to

Returns: RevisionRecord|null RevisionRecord or null on error

◆ newRevisionFromArchiveRow()

MediaWiki\Revision\RevisionStore::newRevisionFromArchiveRow	(		$row,
			$queryFlags = 0,
		PageIdentity	$page = null,
		array	$overrides = [] )

Make a fake RevisionRecord object from an archive table row.

This is queried for permissions or even inserted (as in Special:Undelete)

The user ID and user name may optionally be supplied using the aliases ar_user and ar_user_text (the names of fields which existed before MW 1.34).

MCR migration note: this replaced Revision::newFromArchiveRow

Parameters

\\stdClass	$row
int	$queryFlags
PageIdentity \| null	$page
array	$overrides	associative array with fields of $row to override. This may be used e.g. to force the parent revision ID or page ID. Keys in the array are fields names from the archive table without the 'ar_' prefix, i.e. use 'parent_id' to override ar_parent_id.

Returns: RevisionRecord

Exceptions

MWException

Implements MediaWiki\Revision\RevisionFactory.

See also: newRevisionFromArchiveRow()

Since: 1.35

Parameters

stdClass	$row
null \| stdClass[] \| RevisionSlots	$slots	Database rows generated from a query based on getSlotsQueryInfo with the 'content' flag set. Or RevisionSlots instance
int	$queryFlags
PageIdentity \| null	$page
array	$overrides	associative array with fields of $row to override. This may be used e.g. to force the parent revision ID or page ID. Keys in the array are fields names from the archive table without the 'ar_' prefix, i.e. use 'parent_id' to override ar_parent_id.

Returns: RevisionRecord

◆ newRevisionsFromBatch()

MediaWiki\Revision\RevisionStore::newRevisionsFromBatch	(		$rows,
		array	$options = [],
			$queryFlags = 0,
		PageIdentity	$page = null )

Construct a RevisionRecord instance for each row in $rows, and return them as an associative array indexed by revision ID.

Use getQueryInfo() or getArchiveQueryInfo() to construct the query that produces the rows.

Parameters

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
PageIdentity \| null	$page	The page to which all the revision rows belong, if there is such a page 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 Article Id associated with the page, 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.

◆ updateSlotsOn()

MediaWiki\Revision\RevisionStore::updateSlotsOn	(	RevisionRecord	$revision,
		RevisionSlotsUpdate	$revisionSlotsUpdate,
		IDatabase	$dbw )

Update derived slots in an existing revision into the database, returning the modified slots on success.

Parameters

RevisionRecord	$revision	After this method returns, the $revision object will be obsolete in that it does not have the new slots.
RevisionSlotsUpdate	$revisionSlotsUpdate
IDatabase	$dbw	(primary connection)

Returns: SlotRecord[] the new slot records.

Access: internal

◆ 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 replaced 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 had been deprecated since 1.24 (the Revision class was removed entirely in 1.37).

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
