Branimir Lambov commented on CASSANDRA-10059:
---------------------------------------------
Updated [branch|https://github.com/blambov/cassandra/tree/10059] with fixes for
iteration of range tombstones in {{RangeTombstoneList}}. Forward iteration was
broken on boundaries, reporting invalid {{\[x, x)}} ranges if a range boundary
matches a slice boundary, and reverse iteration was completely broken. The
former shouldn't have caused any real problems, but the latter could cause
reverse range queries to report deleted data which gets fixed with repair or
compaction.
Patch also relaxes the requirement for {{SearchIterator}} to report null on
already queried names as enforcing it would add too much complexity for
questionable benefit.

> Follow up to CASSANDRA-9932. The test coverage for AbstractBTreePartition and
> its hierarchy is entirely indirect. That is not to say it is not covered, but
> we may have some unexplored behaviour. Coverage for BTree is also missing
> around a couple of edges, and the gaps should be filled in.
