Unique index allows duplicate key insert #89

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Adding the same key twice to a unique index should lead to 
UniqueConstraintViolation error. However, the key is being added.

This is due to an incorrect implementation of IntexItem.compareTo() which is 
considering the location as part of the key when searching on leaf nodes.

The existing test case was checking unique constraint violation on non-unique 
indexes, 
which is why this bug was never detected.
