function registry_update

7.x bootstrap.inc registry_update()

Updates the registry based on the latest files listed in the database.

This function should be used when system_rebuild_module_data() does not need to be called, because it is already known that the list of files in the {system} table matches those in the file system.

Return value

TRUE if the registry was rebuilt, FALSE if another thread was rebuilding in parallel and the current thread just waited for completion.
