function poormanscron_exit in Poormanscron 5

Same name and namespace in other branches

1. 6 poormanscron.module \poormanscron_exit()

Implementation of hook_exit().

Checks if poormanscron needs to be run. If this is the case, it invokes the cron hooks of all enabled modules, which are executed after all HTML is returned to the browser. So the user who kicks off the cron jobs should not notice any delay.

File

./poormanscron.module, line 28

A module which runs Drupal cron jobs without the cron application.

Code

function poormanscron_exit() {

  // Calculate when the next poormanscron run is due.
  $lastrun = variable_get('poormanscron_lastrun', 0);
  $nextrun = $lastrun + 60 * variable_get('poormanscron_interval', 60);

  // If the configured time has passed, start the next poormanscron run.
  if (time() > $nextrun) {

    // If this cron run fails to complete, wait a few minutes before retrying.
    variable_set('poormanscron_lastrun', $lastrun + 60 * variable_get('poormanscron_retry_interval', 10));

    // Get the current Drupal messages. Use drupal_set_message() so that
    // the messages aren't deleted in case the cron run fails and
    // we don't get a chance to restore them below.
    $saved_messages = drupal_set_message();

    // Invoke the cron hooks of all enabled modules.
    if (drupal_cron_run()) {
      $message = 'Cron run completed (via poormanscron).';
    }
    else {
      $message = 'Cron run unsuccessful (via poormanscron).';
    }

    // Write a message to the logs if the user wants us to do so.
    if (variable_get('poormanscron_log_cron_runs', 1) == 1) {
      watchdog('cron', $message);
    }
    $t = time();

    // Update the time of the last poormanscron run (this one).
    variable_set('poormanscron_lastrun', $t);

    // Delete any messages added during the cron run (and existing prior
    // messages).
    drupal_get_messages();

    // Restore any prior messages.
    if (isset($saved_messages)) {
      foreach ($saved_messages as $type => $types_messages) {
        foreach ($types_messages as $message) {
