Public Member Functions
	__construct (MimeAnalyzer $mimeAnalyzer, ILoadBalancer $loadBalancer, LinkBatchFactory $linkBatchFactory)

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

	getQueryInfo ()
	Query to do.

	isExpensive ()
	Should this query page only be updated offline on large wikis?

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

Public Member Functions inherited from QueryPage
	delete (LinkTarget $title)
	Remove a cached result.

	deleteAllCachedData ()
	Remove all cached value This is needed when the page is no longer using the cache.

	doQuery ( $offset=false, $limit=false)

	execute ( $par)
	This is the actual workhorse.

	fetchFromCache ( $limit, $offset=false)
	Fetch the query results from the query cache.

	getCachedTimestamp ()

	isCacheable ()

		ILoadBalancer	$loadBalancer,
		LinkBatchFactory	$linkBatchFactory )

Parameters

MimeAnalyzer	$mimeAnalyzer
ILoadBalancer	$loadBalancer
LinkBatchFactory	$linkBatchFactory

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 386 of file SpecialMediaStatistics.php.

◆ getGroupName()

SpecialMediaStatistics::getGroupName ( )

protected

What group to put the page in.

Returns: string

Reimplemented from SpecialPage.

Definition at line 372 of file SpecialMediaStatistics.php.

◆ getOrderFields()

SpecialMediaStatistics::getOrderFields ( )

protected

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 132 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

Reimplemented from QueryPage.

Definition at line 95 of file SpecialMediaStatistics.php.

References $dbr, QueryPage\getDBLoadBalancer(), and NS_MEDIA.

◆ getTableHeaderRow()

SpecialMediaStatistics::getTableHeaderRow ( )

protected

Get (not output) the header row for the table.

Returns: string The header row of the table

Definition at line 314 of file SpecialMediaStatistics.php.

References $header, and SpecialPage\msg().

Referenced by outputTableStart().

◆ isExpensive()

SpecialMediaStatistics::isExpensive ( )

Should this query page only be updated offline on large wikis?

If the query for this page is considered too expensive to run on-demand for large wikis (e.g. every time the special page is viewed), then implement this as returning true.

"Large wikis" are those that enable $wgMiserMode. The value of isExpensive() has no effect by default when $wgMiserMode is off.

It is expected that such large wikis, periodically run the UpdateSpecialPages maintenance script to update these query pages.

By enabling $wgDisableQueryPages, all query pages will be considered as expensive and updated offline only, even query pages that do not mark themselves as expensive.

Stability: stable: to override

Returns: bool

Reimplemented from QueryPage.

Definition at line 77 of file SpecialMediaStatistics.php.

◆ makePercentPretty()

SpecialMediaStatistics::makePercentPretty ( $decimal )

protected

Parameters

float $decimal A decimal percentage (ie for 12.3%, this would be 0.123)
