Detailed Description

Maintenance script that checks for articles to fix after adding/deleting namespaces.

Constructor & Destructor Documentation

◆ __construct()

NamespaceDupes::__construct ( )

Default constructor.

Children should call this first if implementing their own constructors

Stability: stable: to call

Reimplemented from Maintenance.

Definition at line 79 of file namespaceDupes.php.

Member Function Documentation

◆ canMerge()

NamespaceDupes::canMerge	(		$id,
		LinkTarget	$linkTarget,
		&	$logStatus
	)

private

Determine if we can merge a page.

We check if an inaccessible revision would become the latest and deny the merge if so – it's theoretically possible to update the latest revision, but opens a can of worms – search engine updates, recentchanges review, etc.

Parameters

int	$id	The page_id
LinkTarget	$linkTarget	The new link target
string	&$logStatus	This is set to the log status message on failure

Returns: bool

Definition at line 618 of file namespaceDupes.php.

◆ checkAll()

NamespaceDupes::checkAll ( $options )

private

Check all namespaces.

Parameters

array $options Associative array of validated command-line options

Returns: bool

Parameters

array $options Associative array of validated command-line options

Returns: bool

◆ execute()

NamespaceDupes::execute ( )

Do the actual work.

All child classes will need to implement this

Returns: bool|null|void True for success, false for failure. Not returning a value, or returning null, is also interpreted as success. Returning false for failure will cause doMaintenance.php to exit the process with a non-zero exit status.
