Public Member Functions
	__construct ( $name='MediaStatistics')

	formatResult ( $skin, $result)
	This method isn't used, since we override outputResults, but we need to implement since abstract in parent class.

	getOrderFields ()
	How to sort the results.

	getQueryInfo ()
	Query to do.

	isExpensive ()
	Is this query expensive (for some definition of expensive)? Then we don't let it run in miser mode.

	preprocessResults ( $dbr, $res)
	Initialize total values so we can figure out percentages later.

Public Member Functions inherited from QueryPage
	closeList ()

	delete (LinkTarget $title)
	Remove a cached result.

	doQuery ( $offset=false, $limit=false)
	Somewhat deprecated, you probably want to be using execute()

	getRecacheDB ()
	Get a DB connection to be used for slow recache queries.

	getSQL ()
	For back-compat, subclasses may return a raw SQL query here, as a string.

	isCacheable ()
	Is the output of this query cacheable? Non-cacheable expensive pages will be disabled in miser mode and will not have their results written to the querycache table.

Member Function Documentation

◆ formatResult()

SpecialMediaStatistics::formatResult	(		$skin,
			$result )

This method isn't used, since we override outputResults, but we need to implement since abstract in parent class.

Parameters

Skin	$skin
stdClass	$result	Result row

Returns: bool|string|void

Exceptions

MWException

Reimplemented from QueryPage.

Definition at line 358 of file SpecialMediaStatistics.php.

◆ getExtensionList()

SpecialMediaStatistics::getExtensionList ( $mime )

private

Given a mime type, return a comma separated list of allowed extensions.

Parameters

string $mime mime type

Returns: string Comma separated list of allowed extensions (e.g. ".ogg, .oga")

Returns: string

Reimplemented from SpecialPage.

Definition at line 345 of file SpecialMediaStatistics.php.

◆ getOrderFields()

SpecialMediaStatistics::getOrderFields ( )

How to sort the results.

It's important that img_media_type come first, otherwise the tables will be fragmented.

Returns: array Fields to sort by

Reimplemented from QueryPage.

Definition at line 107 of file SpecialMediaStatistics.php.

◆ getQueryInfo()

SpecialMediaStatistics::getQueryInfo ( )

Query to do.

This abuses the query cache table by storing mime types as "titles".

This will store entries like [[Media:BITMAP;image/jpeg;200;20000]] where the form is Media type;mime type;count;bytes.

This relies on the behaviour that when value is tied, the order things come out of querycache table is the order they went in. Which is hacky. However, other special pages like Special:Deadendpages and Special:BrokenRedirects also rely on this.

Returns: array
