[jira] [Created] (DRILL-6343) bit vector copyFromSafe is not doing realloc

Padma Penumarthy created DRILL-6343:
---------------------------------------

             Summary: bit vector copyFromSafe is not doing realloc 
                 Key: DRILL-6343
                 URL: https://issues.apache.org/jira/browse/DRILL-6343
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
    Affects Versions: 1.13.0
            Reporter: Padma Penumarthy
            Assignee: Padma Penumarthy
             Fix For: 1.14.0


bit vector copyFromSafe simply returns false when asked to copy to an index greater than it's capacity. It should do realloc if needed and copy correctly.

This bug is very subtle and shows up as random wrong result. allocateNew for bit vector allocates 4096 bytes initially and if we do copyFromSafe to any index greater than that, we basically do not do any copy, but just return false.
