◆ getRevisionText()

static Revision::getRevisionText	(	$row,
		$prefix = `'old_'`,
		$wiki = `false`
	)

static

Get revision text associated with an old or archive row.

If the text field is not included, this uses RevisionStore to load the appropriate slot and return its serialized content. This is the default backwards-compatibility behavior when reading from the MCR aware database schema is enabled. For this to work, either the revision ID or the page ID must be included in the row.

When using the old text field, the flags field must also be set. Including the old_id field will activate cache usage as long as the $wiki parameter is not set.

Deprecated:: since 1.32, use RevisionStore::newRevisionFromRow instead.

Parameters

stdClass	$row	The text data. If a falsy value is passed instead, false is returned.
string	$prefix	Table prefix (default 'old_')
string \| bool	$wiki	The name of the wiki to load the revision text from (same as the wiki $row was loaded from) or false to indicate the local wiki (this is the default). Otherwise, it must be a symbolic wiki database identifier as understood by the LoadBalancer class.

Returns: string|false Text the text requested or false on failure

◆ newFromRow()

static Revision::newFromRow ( $row )

static

Since: 1.19

MCR migration note: replaced by RevisionStore::newRevisionFromRow(). Note that newFromRow() also accepts arrays, while newRevisionFromRow() does not. Instead, a MutableRevisionRecord should be constructed directly. RevisionStore::newMutableRevisionFromArray() can be used as a temporary replacement, but should be avoided.

Parameters

object | array $row

Returns: Revision

			$id = `0`,
			$flags = `0`
	)

static

Load either the current, or a specified, revision that's attached to a given link target.

If not attached to that link target, will return null.

$flags include: Revision::READ_LATEST : Select the data from the master Revision::READ_LOCKING : Select & lock the data from the master

Parameters

LinkTarget	$linkTarget
int	$id	(optional)
int	$flags	Bitfield (optional)

Returns: Revision|null

◆ newKnownCurrent()

static Revision::newKnownCurrent	(	IDatabase	$db,
			$pageIdOrTitle,
			$revId = `0`
	)

static

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. The title will also be loaded if $pageIdOrTitle is an integer ID.

Parameters

IDatabase	$db	ignored!
int \| Title	$pageIdOrTitle	Page ID or Title object
int	$revId	Known current revision of this page. Determined automatically if not given.

Returns: Revision|bool Returns false if missing

◆ newNullRevision()

static Revision::newNullRevision	(	$dbw,
		$pageId,
		$summary,
		$minor,
		$user = `null`
	)

static

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.

Parameters

IDatabase	$dbw
int	$pageId	ID number of the page to read from
string	$summary	Revision's summary
bool	$minor	Whether the revision should be considered as minor
User \| null	$user	User object to use or null for $wgUser

Returns: Revision|null Revision or null on error
