Detailed Description

Abstract maintenance class for quickly writing and churning out maintenance scripts with minimal effort.

All that must be defined is the execute() method. See docs/maintenance.txt for more info and a quick demo of how to use it.

Terminology: params: registry of named values that may be passed to the script arg list: registry of positional values that may be passed to the script options: passed param values args: passed positional values

In the command: mwscript somescript.php –foo=bar baz foo is a param bar is the option value of the option for param foo baz is the arg value at index 0 in the arg list

Stability: stable: for subclassing

Since: 1.16

Definition at line 55 of file Maintenance.php.

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.
