#tracked_permissions(path) ⇒ Object
Git doesn’t really track file permissions, it just looks at executable bit and uses 0755 if it’s set or 0644 if not. We have to mimic that behavior in the fingerprint calculation to avoid the situation where seemingly clean working copy would trigger new fingerprints for artifacts with changed permissions. Also we don’t want current fingerprints to change, hence the exact values below.
