Perform one update and store the results which will later be displayed on the finished page.

An update function can force the current and all later updates for this module to abort by returning a $ret array with an element like: $ret['#abort'] = array('success' => FALSE, 'query' => 'What went wrong'); The schema version will not be updated in this case, and all the aborted updates will continue to appear on update.php as updates that have not yet been run.

Parameters

$module: The module whose update will be run.

$number: The update number to run.

$context: The batch context array

File

drupal-6.x/update.php, line 150
