Yang Yang commented on CASSANDRA-3390:
--------------------------------------
tested with latest on 1.0 branch (I checked that it does have the 3373 fix)
still same:

> ReadResponseSerializer.serializedSize() calculation is wrong

>
> in ReadResponse.java
> the following code
> public long serializedSize(ReadResponse response, int version)
> {
> int size = DBConstants.intSize;
> size += (response.isDigestQuery() ? response.digest() :
> ByteBufferUtil.EMPTY_BYTE_BUFFER).remaining();
> size += DBConstants.boolSize;
> if (response.isDigestQuery())
> size += response.digest().remaining();
> else
> size += Row.serializer().serializedSize(response.row(), version);
> return size;
> }
> adds the digest size 2 times
> this triggers assertion error in at least ReadVerbHandler
