             Summary: C++ Broker Acl creates too many run-time rules
                 Key: QPID-4123
                 URL: https://issues.apache.org/jira/browse/QPID-4123
             Project: Qpid
          Issue Type: Improvement
          Components: C++ Broker
    Affects Versions: 0.16
            Reporter: Chuck Rolke
            Assignee: Chuck Rolke
            Priority: Minor


The Acl module creates a table rules in a two dimensional array. The typical reference to this table is: actionList[action][objType].

When an Acl rule from the file is processed and the action or objType is '*' then the rule is propagated into the actionList table at every row or column even when the action/object pair will never be references.

For example a rule such as
 acl allow bob publish * name=X routingkey=a.b.c
will put the rule into publish/queue, publish/exchange, publish/broker, etc. even when only publish/exchange will ever be referenced.

In AclModule.h a validationMap is created that identifies which intersections in the actionList are ever used but this map is not used.

With 5 objects and 9 actions there are 45 actionList entries. Of these only 13 are ever referenced for authorise lookups.
