This script compares a release branch against a source branch
(e.g. master) to verify that all cherry-picked commits are
unmodified. It first attempts fast matching using normalized
patch hashes.
If no exact match is found, it falls back to a fuzzy matching
mechanism:
- Filters source commits by matching author and commit subject
- Compares normalized diffs using diff -u
- Selects the closest match based on line difference count
Useful for verifying cherry-picks or rebased commits during
release processes. Supports scan and compare limits for
performance.
