--------------------------------------------

             Summary: Legacy deserializer can create empty range tombstones
                 Key: CASSANDRA-13341
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13341
             Project: Cassandra
          Issue Type: Bug
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
             Fix For: 3.0.x, 3.11.x


Range tombstones in the 2.x file format is a bit far-westy so you can actually get sequences of range tombstones like {{\[1, 4\]@3 \[1, 10\]@5}}. But the current legacy deserializer doesn't handle this correctly. On the first range, it will generate a {{INCL_START(1)@3}} open marker, but upon seeing the next tombstone it will decide to close the previously opened range and re-open with deletion time 5, so will generate {{EXCL_END_INCL_START(1)@3-5}}. That result in the first range being empty, which break future assertions in the code.
