  • xattr.get unused

  • xattr.list unused

  • xattr.remove unused

  • xattr.set unused

3. Testing

Those functions use the override security level, hence aren’t checked. This also means that external functions don’t need to be part of the API.

3.1. Internal

3.2. External

  • hasattr

  • int

  • ord

  • os.lstat

  • os.path.join

  • os.remove

  • pow

  • str

  • tempfile.mktemp removed

  • os.getcwd added

4. Repository format

  • the directory rdiff-backup-data/increments does always exist from the start

  • meta data files are now correctly not compressed when using the --no-compression parameter during a backup or regression

  • introduction of the lock file rdiff-backup-data/lock.yml

Note
 to the best of my knowledge, none of those changes breaks the backward compatibility with older versions of rdiff-backup.
