SpecialGadgetUsage::getDefaultGadgets	(	$gadgetRepo,
		$gadgetIds
	)

array	$gadgetIds	list of gagdet ids registered in the wiki

Returns: array

◆ getGroupName()

SpecialGadgetUsage::getGroupName ( )

protected

Under which header this special page is listed in Special:SpecialPages See messages 'specialpages-group-*' for valid names This method defaults to group 'other'.

Returns: string

Since: 1.21

Reimplemented from SpecialPage.

Definition at line 246 of file SpecialGadgetUsage.php.

◆ getOrderFields()

SpecialGadgetUsage::getOrderFields ( )

Subclasses return an array of fields to order by here.

Don't append DESC to the field names, that'll be done automatically if sortDescending() returns true.

Returns: array

Since: 1.18

Reimplemented from QueryPage.

Definition at line 119 of file SpecialGadgetUsage.php.

◆ getQueryInfo()

SpecialGadgetUsage::getQueryInfo ( )

Define the database query that is used to generate the stats table.

This uses 1 of 2 possible queries, depending on $wgSpecialGadgetUsageActiveUsers.

The simple query is essentially: SELECT up_property, SUM(up_value) FROM user_properties WHERE up_property LIKE 'gadget-' GROUP BY up_property;

The more expensive query is: SELECT up_property, SUM(up_value), count(qcc_title) FROM user_properties LEFT JOIN user ON up_user = user_id LEFT JOIN querycachetwo ON user_name = qcc_title AND qcc_type = 'activeusers' AND up_value = 1 WHERE up_property LIKE 'gadget-' GROUP BY up_property;

Returns: array

Reimplemented from QueryPage.

Definition at line 69 of file SpecialGadgetUsage.php.

References $dbr, DB_SLAVE, and wfGetDB().

◆ isExpensive()

SpecialGadgetUsage::isExpensive ( )

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

$wgDisableQueryPages causes all query pages to be declared expensive. Some query pages are always expensive.

Returns: bool

Reimplemented from QueryPage.

Definition at line 46 of file SpecialGadgetUsage.php.

◆ outputResults()

SpecialGadgetUsage::outputResults	(	$out,
		$skin,
		$dbr,
		$res,
		$num,
		$offset

int	$num	Number of available result rows
int	$offset	Paging offset
