Anoop Sam John updated HBASE-20078:
-----------------------------------
Description:
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.
