Implements hook_update_dependencies().

File

modules/system/system.install, line 1824
Install, update and uninstall functions for the system module.

Code

function system_update_dependencies() {

  // system_update_7053() queries the {block} table, so it must run after
  // block_update_7002(), which creates that table.
  $dependencies['system'][7053] = array(
    'block' => 7002,
  );

  // system_update_7061() queries the {node_revision} table, so it must run
  // after node_update_7001(), which renames the {node_revisions} table.
  $dependencies['system'][7061] = array(
    'node' => 7001,
  );

  // system_update_7067() migrates role permissions and therefore must run
  // after the {role} and {role_permission} tables are properly set up, which
  // happens in user_update_7007().
  $dependencies['system'][7067] = array(
    'user' => 7007,
  );
  return $dependencies;
