Code

protected function assetDiff(array $assets, array $start_assets, $diff_function) {
    $diff = $diff_function($assets, $start_assets);
    // Cleanup the resulting array since drupal_array_diff_assoc_recursive() can
    // leave half populated arrays behind.
    foreach ($diff as $key => $entry) {
        // If only the weight was different we can remove this entry.
        if (count($entry) == 1 && isset($entry['weight'])) {
            unset($diff[$key]);
        }
        elseif ($entry != $assets[$key]) {
            $diff[$key] = $assets[$key];
        }
    }
    return $diff;
