Detailed Description

Delete unused local passwords.

Mainly intended to be used as a base class by authentication extensions to provide maintenance scripts which allow deleting local passwords for users who have another way of logging in. Such scripts would customize how to locate users who have other login methods and don't need local login anymore. Make sure to set LocalPasswordPrimaryAuthenticationProvider to loginOnly => true or disable it completely before running this, otherwise it might recreate passwords.

This class can also be used directly to just delete all local passwords, or those for a specific user. Deleting all passwords is useful when the wiki has used local password login in the past but it has been disabled.

Constructor & Destructor Documentation

__construct()

DeleteLocalPasswords::__construct

(

)

Default constructor.

Children should call this first if implementing their own constructors

Reimplemented from Maintenance.

Definition at line 51 of file DeleteLocalPasswords.php.

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

Member Function Documentation

execute()

DeleteLocalPasswords::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 96 of file DeleteLocalPasswords.php.

References getUserBatches(), getUserDB(), initialize(), Maintenance\output(), and processUsers().

getUserBatches()

DeleteLocalPasswords::getUserBatches ( )

protected

This method iterates through the requested users and returns their names in batches of self::$mBatchSize.

Subclasses should reimplement this and locate users who use the specific authentication method. The default implementation just iterates through all users. Extensions that work with wikifarm should also update self::getUserDB() as necessary.

Returns

getUserDB()

DeleteLocalPasswords::getUserDB ( )

protected

Get the master DB handle for the current user batch.

This is provided for the benefit of authentication extensions which subclass this and work with wiki farms.
