◆ getContentBlobsForBatch()

MediaWiki\Revision\RevisionStore::getContentBlobsForBatch	(	$rowsOrIds,

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

	)

private

Loads a Content object based on a slot row.

This method does not call $slot->getContent(), and may be used as a callback called by $slot->getContent().

MCR migration note: this roughly corresponded to Revision::getContentInternal

Parameters

SlotRecord	$slot	The SlotRecord to load content for
string \| null	$blobData	The content blob, in the form indicated by $blobFlags
string \| null	$blobFlags	Flags indicating how $blobData needs to be processed. Use null if no processing should happen. That is in contrast to the empty string, which causes the blob to be decoded according to the configured legacy encoding.
string \| null	$blobFormat	MIME type indicating how $dataBlob is encoded
int	$queryFlags

Exceptions

RevisionAccessException

Returns: Content

◆ newNullRevision()

MediaWiki\Revision\RevisionStore::newNullRevision	(	IDatabase	$dbw,
		PageIdentity	$page,
		CommentStoreComment	$comment,
			$minor,
		UserIdentity	$user
	)

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 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

	)

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.

	)

private

Given a set of conditions, fetch a revision.

This method should be used if we are pretty sure the revision exists. Unless $flags has READ_LATEST set, this method will first try to find the revision on a replica before hitting the primary database.

MCR migration note: this corresponded to Revision::newFromConds

Parameters

array	$conditions
int	$flags	(optional)
PageIdentity \| null	$page	(optional)
array	$options	(optional) additional query options

Returns: RevisionRecord|null

Parameters

◆ 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.

◆ newRevisionSlots()

MediaWiki\Revision\RevisionStore::newRevisionSlots	(		$revId,

	)

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[] \| null	$slotRows
int	$queryFlags
PageIdentity	$page

Returns: RevisionSlots
