◆ getEtag()

MediaWiki\Rest\Handler\PageHistoryCountHandler::getEtag ( )

protected

Choosing to not implement etags in this handler.

Generating an etag when getting revision counts must account for things like visibility settings (e.g. rev_deleted bit) which requires hitting the database anyway. The response for these requests are so small that we wouldn't be gaining much efficiency. Etags are strong validators and if provided would take precendence over last modified time, a weak validator. We want to ensure only last modified time is used since it is more efficient than using etags for this particular case.

Returns: null

Definition at line 365 of file PageHistoryCountHandler.php.

◆ getLastModified()

MediaWiki\Rest\Handler\PageHistoryCountHandler::getLastModified ( )

protected

Returns latest of 2 timestamps:

Current revision
OR entry from the DB logging table for the given page
Returns
int|null

Reimplemented from MediaWiki\Rest\Handler.

Definition at line 310 of file PageHistoryCountHandler.php.

◆ getLastModifiedTimes()

MediaWiki\Rest\Handler\PageHistoryCountHandler::getLastModifiedTimes ( )

protected

Returns array with 2 timestamps:

Current revision
OR entry from the DB logging table for the given page
Returns
array

◆ getMinorCount()

MediaWiki\Rest\Handler\PageHistoryCountHandler::getMinorCount	(		$pageId,
		RevisionRecord	$fromRev = `null`
	)

protected

Parameters

int	$pageId	the id of the page to load history for
RevisionRecord \| null	$fromRev

Returns: int the count

◆ getPage()

MediaWiki\Rest\Handler\PageHistoryCountHandler::getPage ( )

private

Returns: ExistingPageRecord|null

References MediaWiki\Rest\Handler\getValidatedParams().

Referenced by MediaWiki\Rest\Handler\PageHistoryCountHandler\getCount(), MediaWiki\Rest\Handler\PageHistoryCountHandler\getCurrentRevision(), and MediaWiki\Rest\Handler\PageHistoryCountHandler\run().

◆ getParamSettings()

MediaWiki\Rest\Handler\PageHistoryCountHandler::getParamSettings ( )

Fetch ParamValidator settings for parameters.

Every setting must include self::PARAM_SOURCE to specify which part of the request is to contain the parameter.

Can be used for validating parameters inside an application/x-www-form-urlencoded or multipart/form-data POST body (i.e. parameters which would be present in PHP's $_POST array). For validating other kinds of request bodies, override getBodyValidator().

Stability: stable: to override

Returns: array[] Associative array mapping parameter names to ParamValidator settings arrays

Reimplemented from MediaWiki\Rest\Handler.

◆ getRevertedCount()

MediaWiki\Rest\Handler\PageHistoryCountHandler::getRevertedCount	(		$pageId,
		RevisionRecord	$fromRev = `null`
	)

protected

Parameters

int	$pageId	the id of the page to load history for
RevisionRecord \| null	$fromRev

Parameters

int $revId

Returns: RevisionRecord

◆ loggingTableTime()

MediaWiki\Rest\Handler\PageHistoryCountHandler::loggingTableTime ( $pageId )

private

Return timestamp of latest entry in logging table for given page id.

Parameters

int $pageId

Returns: int|null

Definition at line 345 of file PageHistoryCountHandler.php.

References $res, DB_REPLICA, and wfTimestamp().

◆ needsWriteAccess()

MediaWiki\Rest\Handler\PageHistoryCountHandler::needsWriteAccess ( )

Indicates whether this route requires write access.

The handler should override this if the route does not need to write to the database.

This should return true for routes that may require synchronous database writes. Modules that do not need such writes should also not rely on primary database access, since only read queries are needed and each primary DB is a single point of failure.

Stability: stable: to override

Returns: bool

	)

private

Reorders revisions if they are present.

Parameters
