             Summary: C++ broker has odd treatment of empty and whitespace only selectors
                 Key: QPID-5874
                 URL: https://issues.apache.org/jira/browse/QPID-5874
             Project: Qpid
          Issue Type: Bug
          Components: C++ Broker
    Affects Versions: 0.28
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher
            Priority: Minor


The selector parser in the C++ broker treats empty selectors oddly:

If the selector is a completely empty string : "" then the selector is treated as if it was always true. However if the selector only contains white space : " " then this treated as a parse error.

These 2 cases are for all visible user purposes the same selector and so should have the same behaviour.

Probably the most logical behaviour is to make both these cases act as if the selector was always true so that they are equivalent to the selector being entirely absent.
