Full URI not passed to demo_admin_settings_validate

When trying to setup automated resets, kept receiving an error "The snapshot directory demo could not be created."

Did some digging and the offender was the call to file_prepare_directory in demo_admin_settings_validate [demo.admin.inc]. As the "private://" stream identifier was not passed, the file_prepare_directory function would fail as there would be no directory to find. Adding in the stream identifier so there was a full URI to parse fixed the issue.

Before Fix

function demo_admin_settings_validate($form, &$form_state) {
  if (!file_prepare_directory($form_state['values']['demo_dump_path'], FILE_CREATE_DIRECTORY)) {
    form_set_error('demo_dump_path', t('The snapshot directory %directory could not be created.', array('%directory' => $form_state['values']['demo_dump_path'])));
  }
}

After Fix

function demo_admin_settings_validate($form, &$form_state) {
 $fullpath = 'private://'.$form_state['values']['demo_dump_path'];
 $dirprep = file_prepare_directory($fullpath, FILE_CREATE_DIRECTORY);
 if (!$dirprep) {
   form_set_error('demo_dump_path', t('The snapshot directory %directory could not be created.', array('%directory' => $form_state['values']['demo_dump_path'])));
  }
}
