Helper function to mimic hook_node_grants_alter() and trace what each module does with it.


object $grants: An indexed array of grant records, augmented by the '#module' key, as created by _devel_node_access_module_invoke_all('node_grants'). This array is updated by the hook_node_grants_alter() implementations.

$node: The node that the grant records belong to.

Return value

A tree representation of the grant records in $grants including their history: $data[$realm][$gid] ['cur'] - TRUE or FALSE whether the gid is present or not ['ori'][] - array of module names that contributed this grant (if any) ['chg'][] - array of changes, such as

  • 'added' if module name is a prefix if the $realm,
  • 'added by module' otherwise, or
  • 'removed by module'

This module gives developers feedback as to what their node_access table contains, and which nodes are protected or visible to the public.
