1 node.module | _node_access_rebuild_batch_operation(&$context) |
Performs batch operation for node_access_rebuild().
This is a multistep operation: we go through all nodes by packs of 20. The batch processing engine interrupts processing and sends progress feedback after 1 second execution time.
Parameters
array $context: An array of contextual key/value information for rebuild batch process.
