◆ 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$rowThe text data. If a falsy value is passed instead, false is returned.
string$prefixTable prefix (default 'old_')
string | bool$wikiThe 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

◆ 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$dbignored!
int | Title$pageIdOrTitlePage ID or Title object
int$revIdKnown current revision of this page. Determined automatically if not given.
Returns
Revision|bool Returns false if missing

static Revision::newNullRevision (   $dbw,
