------------------------------------------------
Summary: Range.subtractContained produces incorrect results when
used on full ring
Key: CASSANDRA-14869
URL: https://issues.apache.org/jira/browse/CASSANDRA-14869
Project: Cassandra
Issue Type: Bug
Reporter: Aleksandr Sorokoumov
Assignee: Aleksandr Sorokoumov
Fix For: 3.0.x, 3.11.x, 4.0.x
Attachments: range bug.jpg
The bug is in the way {{Range.subtractContained}} works if minuend range covers
the full ring and subtrahend range goes over 0 (see illustration). For example,
{{(-50, 50] - (10, 100]}} returns \{{{(50,10], (100,50]}}} instead of
\{{(100,10]}}.
