stack commented on HBASE-20078:
-------------------------------
Thanks [~anoop.hbase] Agree buffers of this size will never happen. Helped me
fix a bug in getShort though (smile). Thanks.
> Add more unit tests of MultiByteBuff facility

> Key: HBASE-20078
> URL: https://issues.apache.org/jira/browse/HBASE-20078
> Project: HBase
> Issue Type: Task
> Components: test
> Reporter: stack
> Assignee: stack
> Priority: Major
>
> Copied from the bottom of HBASE-13916, the JIRA that introduced MultiByteBuff:
> [~anoop.hbase] This bit of code needs more test. It does not seem to be doing
> the right thing....
> Doing something like the below, it does not seem to be returning the right
> answers....
> {code}
> @Ignore // This test fails.
> @Test
> public void testGetInt() {
> ByteBuffer bb1 = ByteBuffer.allocate(1);
> bb1.put((byte)1);
> ByteBuffer bb2 = ByteBuffer.allocate(1);
> bb2.put((byte)0);
> ByteBuffer bb3 = ByteBuffer.allocate(1);
> bb3.put((byte)0);
> ByteBuffer bb4 = ByteBuffer.allocate(1);
> bb4.put((byte)1);
> MultiByteBuff mbb = new MultiByteBuff(bb1, bb2, bb3, bb4);
> // Value is wrong here ... needs adjusting but code is doing wrong thing.
> assertEquals(256, mbb.getIntAfterPosition(0));
> }
> {code}
> Ignore the expected answer in the above... just a place holder as i messed
> with the return... but if I make buffers of one byte, we do not seem to be
> moving into the next buffer properly... If I make the buffers of two bytes,
> similar. This stuff normally works because we are not spanning buffer
> boundaries... but if we do, response seems like it could be off sir. I'll
> have a go at this. You might have input meantime.
