Thiruvalluvan M. G. updated AVRO-1097:
--------------------------------------
Attachment: AVRO-1097.patch
This patch addresses the issue by checking if there are indeed bytes to be
decoded. If not, it throws an EOFException. If there are some bytes and they do
not constitute a valid Zigzag encoding, it throws "Invalid int/long encoding"
exception.
> BinaryDecoder does not detect EOF sometimes

> This is the first problem reported in AVRO-1058.
> The trouble is, in case of end of stream, ensureBounds() does not really
> ensure that the requisite number of actual bytes are available in the buffer.
> It merely ensures that there won't be array index overflow. readInt() and
> readLong() check for overflow at the very end. But these two methods continue
> to read whatever bytes are in the buffer and interpret. If the bytes do not
> really belong to the stream (because of EOF), they need not be valid Zigzag
> encoding. That is the reason we get the "Invalid int encoding" exception.
