Justin Sampson added a comment -

The chunked encoding implemented for PRV-22 accomplishes this, though slightly differently than suggested here. Each transaction is preceded by its size in bytes and followed by a CRLF pair, so if either not enough bytes remain in the file, or the bytes are not followed by CRLF, we know the transaction was not written fully.
