[jira] Commented: (CASSANDRA-2256) BRAF assertion error

["Pavel Yaskevich (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-2256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13001502#comment-13001502 ] 

Pavel Yaskevich commented on CASSANDRA-2256:
--------------------------------------------

Test for the problem:
{code}
public void testAssertOnRead() throws IOException
    {
        BufferedRandomAccessFile file = createTempFile("braf");
        file.write(new byte[10]);
        file.sync();

        BufferedRandomAccessFile copy = new BufferedRandomAccessFile(file.getPath(), "r");

        copy.seek(15);
        copy.read();

        file.close();
        copy.close();
    }
{code}

This happens when you are trying to seek to position > file length on read-only file and then read (because fileLength is cached, method isEOF() does not work properly). I don't think that we should allow such seeks.
