Stu Hood commented on CASSANDRA-1661:
-------------------------------------
* A few of the loops involving direct array access (in particular the one in
RandomPartitioner) could be simplified with judicious use of mark() and get()
* Adding the follow function and using it in the tests would clarify things a
lot: CFSTest looks like it exploded.
{code:java}public static ByteBuffer bytes(String s) { return
ByteBuffer.wrap(s.getBytes(UTF_8)); }{code}
* Converting BytesToken to ByteBuffer storage would clean up a ton of special
casing (should probably be tackled in a separate issue though)
* ByteBufferTest is literally a test of ByteBuffers: I don't think it should be
in C*
Thanks!
> Use of ByteBuffer limit() must account for arrayOffset()

> There are a few places in the code where it loops across a byte buffers
> backing array wrong:
> for (int i=bytes.position()+bytes.arrayOffset(); i<bytes.limit(); i++)
> This is incorrect as the limit() does not account for arrayOffset()
> for (int i=bytes.position()+bytes.arrayOffset();
> i<bytes.limit()+bytes.arrayOffset(); i++)
> is the correct code.
> There is also a few places where the unit tests would fail if we used non
> wrapped byte arrays.
