I have coded a module to modify access to nodes; but when I rebuild permissions, it starts at node 1, goes counting, and then when it reaches 49 it starts rebuilding permission for node 35. My custom function to write permissions is: function wu_node_access_records($node) { $extra_strings=module_invoke_all('wu_node_access_records', $node); //this allow other modules to add strings sort($extra_strings); // idem $res=db_query("SELECT * FROM {wu_nodes} WHERE nid=%d",$node->nid); while ($row=db_fetch_object($res)) $grants[] = array( 'realm' => 'wu_'.$row->wu_realm.(!empty($extra_strings) ? " <###> ".implode(" <###> ", $extra_strings): ""), 'gid' => $row->wu_nid, 'grant_view' => 1, 'grant_update' => 1, 'grant_delete' => 1, 'priority' => 0, //maybe should be increased ); drupal_set_message("rebuilding node: ".$node->nid."-".$node->vid); //debug return isset($grants) ? $grants : NULL; } and it returns: * rebuilding node: 1-1 * rebuilding node: 23-23 * rebuilding node: 24-24 * rebuilding node: 27-27 * rebuilding node: 28-28 * rebuilding node: 29-29 * rebuilding node: 30-30 * rebuilding node: 31-31 * rebuilding node: 32-32 * rebuilding node: 33-33 * rebuilding node: 34-34 * rebuilding node: 35-35 * rebuilding node: 36-36 * rebuilding node: 40-40 * rebuilding node: 42-42 * rebuilding node: 43-43 * rebuilding node: 44-44 * rebuilding node: 45-45 * rebuilding node: 35-35 * rebuilding node: 47-47 * rebuilding node: 48-48 * rebuilding node: 49-49 * rebuilding node: 35-35 * rebuilding node: 35-35 * The content access permissions have been rebuilt.
