Tyler Hobbs created CASSANDRA-9239:
--------------------------------------
Summary: OHCProvider doesn't write ByteBuffers with non-zero
position correctly
Key: CASSANDRA-9239
URL: https://issues.apache.org/jira/browse/CASSANDRA-9239
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Tyler Hobbs
Assignee: Tyler Hobbs
Priority: Minor
Fix For: 3.0
Attachments: use-buffer-position.txt
In {{OHCProvider.DataOutputPlusAdapter.write()}}, we do the following:
{noformat}
if (buffer.hasArray())
out.write(buffer.array(), buffer.arrayOffset(), buffer.remaining());
{noformat}
This doesn't behave correctly if the ByteBuffer has a non-zero position.
Instead, we need to add {{buffer.position()}} to {{buffer.arrayOffset()}}.
At least against CASSANDRA-8099, this has the effect of writing incorrect row
cache entries.
