Configuration options for Updater class.

class UpdaterConfig(max_root_rotations=32, max_delegations=32, root_max_length=512000, timestamp_max_length=16384, snapshot_max_length=2000000, targets_max_length=5000000, prefix_targets_with_hash=True)

Used to store Updater configuration.

  • max_root_rotations (int) – Maximum number of root rotations.

  • max_delegations (int) – Maximum number of delegations.

  • root_max_length (int) – Maxmimum length of a root metadata file.

  • timestamp_max_length (int) – Maximum length of a timestamp metadata file.

  • snapshot_max_length (int) – Maximum length of a snapshot metadata file.

  • targets_max_length (int) – Maximum length of a targets metadata file.

  • prefix_targets_with_hash (bool) – When consistent snapshots are used, target download URLs are formed by prefixing the filename with a hash digest of file content by default. This can be overridden by setting prefix_targets_with_hash to False.
