[jira] [Created] (CASSANDRA-10002) Repeated slices on RowSearchers are incorrect

Tyler Hobbs created CASSANDRA-10002:
---------------------------------------

             Summary: Repeated slices on RowSearchers are incorrect
                 Key: CASSANDRA-10002
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10002
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Tyler Hobbs
            Assignee: Tyler Hobbs
             Fix For: 3.0 beta 1


In {{AbstractThreadUnsafePartition}}, repeated {{slice()}} calls on a {{RowSearcher}} can produce incorrect results.  This is caused by only performing a binary search over a sublist (based on {{nextIdx}}), but not taking {{nextIdx}} into account when using the search result index.

I made a quick fix in [this commit|https://github.com/thobbs/cassandra/commit/73725ea6825c9c0da1fa4986b01f39ae08130e10] on one of my branches, but the full fix also needs to cover {{ReverseRowSearcher}} and include a test to reproduce the issue.
