------------------------------------------
Summary: Mutated ColumnFamily is not available to per-row indexes
during update
Key: CASSANDRA-7742
URL: https://issues.apache.org/jira/browse/CASSANDRA-7742
Project: Cassandra
Issue Type: Bug
Reporter: Sam Tunnicliffe
Assignee: Sam Tunnicliffe
PerRowSecondaryIndex implementations are updated when
SecondaryIndexManager.Updater.updateRowLevelIndexes is called from
AtomicBTreeColumns.addAllWithSizeDelta. The StandardUpdater implementation does
this by passing the key and cf from the incoming Mutation to the PRSI.index()
method. However, the StandardUpdater instance created in Keyspace.apply() does
not wrap the Mutation's cf as it is obtained using the wrong factory method.
This results in the cf passed to the PRSI always being null.
This isn't caught by PerRowSecondaryIndexTest because the stub index
implementation there only verifies that the latest version of the cf can be
obtained by the index reading from the base cf.
Attaching a trivial patch to obtain an Updater which does wrap the mutated cf
and also fix the test so it verifies both of the actual arguments passed to
PRSI.index
