Revoking a privilege from a table should invalidate statements dependent on
that table
--------------------------------------------------------------------------------------
Key: DERBY-2594
URL: https://issues.apache.org/jira/browse/DERBY-2594
Project: Derby
Issue Type: Improvement
Components: SQL
Affects Versions: 10.2.1.6
Reporter: Dyre Tjeldvoll
Assigned To: Dyre Tjeldvoll
Revoking a privilege on a table will currently cause the
DependencyManager.invalidateFor() to be called on the table's
TablePermsDescriptor with the action=REVOKE_PRIVILEGE. However, the prepared
statements that refer to that table are dependents of the table's
TableDescriptor, but NOT its TablePermsDescriptor, so the statements are not
invalidated after revoke.
This problem is currently hidden by the fact that authorization is checked on
every execution, but this will change when language result sets are no longer
reused (see DERBY-827).
