Hi,
After much discussion and 10 iterations of reviews, this proposal has
evolved from what was the original isSameContent method to a mismatch
method. API-wise, a compare method was also considered as it looked like
just a short step forward from mismatch, however, it was eventually
dropped since there is no convincing use case comparing files
lexicographically by contents. Impl-wise, extensive performance
benchmarking has been done to compare a buffered reading vs memory
mapping, the result was that a simple buffered reading performed better
among small files, and those with the mismatched byte closer to the
beginning of files. Since the proposed method's targeted files are small
ones, the impl currently does a buffered reading only.
Please review.
