Detailed Description

Constructor & Destructor Documentation

◆ __construct()

RefreshLinks::__construct ( )

Default constructor.

Children should call this first if implementing their own constructors

Stability: stable
to call

Reimplemented from Maintenance.

Definition at line 38 of file refreshLinks.php.

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

Member Function Documentation

◆ execute()

RefreshLinks::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.

Reimplemented from Maintenance.

◆ fixLinksFromArticle()

static RefreshLinks::fixLinksFromArticle ( $id)
static

Run LinksUpdate for all links on a given page_id.

Parameters
int$idThe page_id

Definition at line 236 of file refreshLinks.php.

◆ fixRedirect()

static RefreshLinks::fixRedirect ( Maintenance $maint,
$id )
static

Update the redirect entry for a given page.

This methods bypasses the "redirect" table to get the redirect target, and parses the page's content to fetch it. This allows to be sure that the redirect target is up to date and valid. This is particularly useful when modifying namespaces to be sure the entry in the "redirect" table points to the correct page and not to an invalid one.

Access: internal
Parameters
Maintenance$maint
int$idThe page ID to check
