> BTreeScan.isCurrentPositionDeleted() should return true if the row has been
> purged

> Key: DERBY-4086
> URL: https://issues.apache.org/jira/browse/DERBY-4086
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.4.2.0
> Reporter: Knut Anders Hatlen
> Priority: Minor
>
> Currently, BTreeScan.isCurrentPositionDeleted() returns false if the current
> position has been purged (that is, if reposition(scan_position, false)
> returns false). Since a row must be deleted in order to be purged, I believe
> it is more correct if isCurrentPositionDeleted() returns true in this case.
> (I'm not sure if it is possible to exercise this code path in the current
> code. It is not exercised by any of the existing regression tests. Its only
> caller, TableScanResultSet.getCurrentRow(), also calls
> doesCurrentPositionQualify() which correctly returns false in this case, and
> it therefore skips the row and hides this problem. So even if the code can be
> exercised, it shouldn't cause any observable problems at this time.)
