Implementation of hook_cron

Delete old batches from the batch_queue table. These would be normal "old" batches we no longer need, or ones that never finished for some reason and are just taking up space.

Code

function batch_cron() {

  $older_than = strtotime("2 HOURS AGO");
  db_query("DELETE FROM batch_queue WHERE created <= ? ", $older_than);


  // Should we check to see if there are any temp files to delete?
  if (time() > variable_get("batch_check_to_delete_temp_files", 0)) {
    // Also look for any "batch_" files which are too old.
    $private_path = fp_get_files_path() . "/private";

    $files = scandir($private_path);
    foreach ($files as $file) {

      if (str_starts_with($file, "batch_") && str_ends_with($file, ".tmp")) {
        $temp = explode("__", $file);
        $temp2 = explode(".", $temp [1]);
        $ts = intval($temp2 [0]);

        if ($ts > 999) { // hopefully this is a valid timestamp
          if ($ts <= $older_than) {
            // Yes, we can delete now.
            watchdog("batch", "Delete old temp file: " . $file, array(), WATCHDOG_DEBUG);
            unlink($private_path . '/' . $file);
          }
        }

      }
    } // foreach file


    // Set a new time to check to delete temp files...
    variable_set("batch_check_to_delete_temp_files", strtotime("NOW + 2 HOURS"));

  } // if time > variable_get....
