function tracker_cron in Drupal 10

Same name and namespace in other branches

1. 8 core/modules/tracker/tracker.module \tracker_cron()
2. 7 modules/tracker/tracker.module \tracker_cron()
3. 9 core/modules/tracker/tracker.module \tracker_cron()

Implements hook_cron().

Updates tracking information for any items still to be tracked. The state 'tracker.index_nid' is set to ((the last node ID that was indexed) - 1) and used to select the nodes to be processed. If there are no remaining nodes to process, 'tracker.index_nid' will be 0. This process does not run regularly on live sites, rather it updates tracking info once on an existing site just after the tracker module was installed.
