With the new hashing routine, null values are taken into account when computing row digest. Previous behavior had a regression which stopped computing the hash after the first null value is encountered, but the original behavior was also prone to errors - e.g. row [1, NULL, 2] was not distinguishable from [1, 2, NULL], because their hashes were identical. This hashing is not yet active - it will only be used after the next commit introduces a proper cluster feature for it.
