diff tests/test-addremove-similar @ 4135:6cb6cfe43c5d

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Avoid some false positives for addremove -s The original code uses the similary score 1 - len(diff(after, before)) / len(after) The diff can at most be the size of the 'before' file, so any small 'before' file would be considered very similar. Removing an empty file would cause all files added in the same revision to be considered copies of the removed file. This changes the metric to bytes_overlap(before, after) / len(before + after) i.e. the actual percentage of bytes shared between the two files.
