Detailed Description

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

Definition at line 40 of file namespaceDupes.php.

Constructor & Destructor Documentation

◆ __construct()

NamespaceConflictChecker::__construct ( )

Default constructor.

Children should call this first if implementing their own constructors

Reimplemented from Maintenance.

Definition at line 53 of file namespaceDupes.php.

References Maintenance\addDescription(), and Maintenance\addOption().

Member Function Documentation

◆ canMerge()

NamespaceConflictChecker::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

integer	$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 561 of file namespaceDupes.php.

◆ checkAll()

NamespaceConflictChecker::checkAll ( $options )

private

Check all namespaces.

Parameters

array $options Associative array of validated command-line options
