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 76 of file RevisionStore.php.

Constructor & Destructor Documentation

◆ __construct()

Revision\RevisionStore::__construct	(	ILoadBalancer	$loadBalancer,
		SqlBlobStore	$blobStore,
		WANObjectCache	$cache,
		CommentStore	$commentStore,
		NameTableStore	$contentModelStore,
		NameTableStore	$slotRoleStore,
		SlotRoleRegistry	$slotRoleRegistry,
			$mcrMigrationStage,
		ActorMigration	$actorMigration,
			$wikiId = `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 $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.
CommentStore	$commentStore
NameTableStore	$contentModelStore
NameTableStore	$slotRoleStore
SlotRoleRegistry	$slotRoleRegistry
int	$mcrMigrationStage	An appropriate combination of SCHEMA_COMPAT_XXX flags

◆ emulateContentId()

Revision\RevisionStore::emulateContentId ( $textId )

private

Provides a content ID to use with emulated SlotRecords in SCHEMA_COMPAT_OLD mode, based on the revision's text ID (rev_text_id or ar_text_id, respectively).

Note that in SCHEMA_COMPAT_WRITE_BOTH, a callback to findSlotContentId() should be used instead, since in that mode, some revision rows may already have a real content ID, while other's don't - and for the ones that don't, we should indicate that it is missing and cause SlotRecords::hasContentId() to return false.

Parameters

int $textId

Returns: int The emulated content ID

◆ newNullRevision()

Revision\RevisionStore::newNullRevision	(	IDatabase	$dbw,
		Title	$title,

			$minor,

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.

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 replaces 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
Title	$title	Title of the page to read from
CommentStoreComment	$comment	RevisionRecord's summary
bool	$minor	Whether the revision should be considered as minor
User	$user	The user to attribute the revision to

MCR migration note: this replaces Revision::newFromArchiveRow

Parameters

object	$row
int	$queryFlags
Title \| null	$title
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.
