Detailed Description

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

Definition at line 43 of file namespaceDupes.php.

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 81 of file namespaceDupes.php.

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

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 637 of file namespaceDupes.php.

Referenced by checkNamespace().

◆ checkAll()

NamespaceDupes::checkAll ( $options )

private

Check all namespaces.

Parameters

array $options Associative array of validated command-line options

Returns: bool

Definition at line 133 of file namespaceDupes.php.

		$extraConds = `[]`
	)

private

Check and repair the destination fields in a link table.

Parameters

string	$table	The link table name
string	$fieldPrefix	The field prefix in the link table
int	$ns	Destination namespace id
string	$name
array	$options	Associative array of validated command-line options

string	$name
array	$options	Associative array of validated command-line options

◆ checkPrefix()

NamespaceDupes::checkPrefix ( $options )

Move the given pseudo-namespace, either replacing the colon with a hyphen (useful for pseudo-namespaces that conflict with interwiki links) or move them to another namespace if specified.

Parameters

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.
