Additional Inherited Members
Static Public Member Functions inherited from Maintenance
static	getTermSize ()
	Get the terminal size as a two-element array where the first element is the width (number of columns) and the second element is the height (number of rows).
static	posix_isatty ( $fd)

static	setLBFactoryTriggers (LBFactory $LBFactory, Config $config)

Detailed Description

Maintenance script that looks for 'orphan' revisions hooked to pages which don't exist and 'childless' pages with no revisions.

Definition at line 42 of file orphans.php.

Constructor & Destructor Documentation

__construct()

Orphans::__construct

(

)

Default constructor.

Children should call this first if implementing their own constructors

Reimplemented from Maintenance.

Definition at line 43 of file orphans.php.

Member Function Documentation

checkOrphans()

Orphans::checkOrphans (   $fix )

private

Check for orphan revisions.

Parameters

bool

$fix

Whether to fix broken revisions when found

Definition at line 77 of file orphans.php.

References as, DB_MASTER, Maintenance\getDB(), lockTables(), and Maintenance\output().

Referenced by execute().

checkSeparation()

Orphans::checkSeparation (   $fix )

private

Check for pages where page_latest is wrong.

Parameters

bool

$fix

Whether to fix broken entries

Definition at line 194 of file orphans.php.

References $article, $title, as, DB_MASTER, Maintenance\getDB(), lockTables(), Revision\newFromId(), and Maintenance\output().

Referenced by execute().

checkWidows()

Orphans::checkWidows (   $fix )

private

Parameters

bool

$fix

Todo:

DON'T USE THIS YET! It will remove entries which have children, but which aren't properly attached (eg if page_latest is bogus but valid revisions do exist)

Definition at line 148 of file orphans.php.

References as, DB_MASTER, Maintenance\getDB(), lockTables(), and Maintenance\output().

execute()

Orphans::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.

Definition at line 53 of file orphans.php.

References checkOrphans(), checkSeparation(), and Maintenance\hasOption().

lockTables()

Orphans::lockTables (   $db,   $extraTable = []  )

private

Lock the appropriate tables for the script.

Parameters

IMaintainableDatabase	$db
string[]	$extraTable	The name of any extra tables to lock (eg: text)
