Yang Yang commented on CASSANDRA-3390:
--------------------------------------
I mean
buffer.getData().length returns the underlying byte[] length, which is always
doubled on expansion, so this will not be the same as the actual bytes written
buffer.getLength() returns the "count" var, yes, this should be the same as
the serializedSize() calculation
> 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
