Infinite loop in StreamFileContainer.writeColumn
------------------------------------------------
Key: DERBY-4519
URL: https://issues.apache.org/jira/browse/DERBY-4519
Project: Derby
Issue Type: Bug
Components: Store
Affects Versions: 10.5.3.0, 10.4.2.0, 10.3.3.0, 10.2.2.0, 10.1.3.1, 10.0.2.1
Reporter: Kristian Waagan
Assignee: Kristian Waagan
Fix For: 10.6.0.0
The offset and length argument have been swapped in the calls to
InputStream.read(byte,offset, length) and write(byte,offset, length). This code
is inside a do-while (true) loop, and the only normal way out is when
InputStream.read returns -1. This will never happen since the stream is asked
to read zero bytes. Derby ends up eating up all available CPU, limited to a
single core / CPU.
The bug hasn't been observed because Derby is materializing all values when
calling this code. Enabling streaming capabilities in the sorter revealed it.
