Release v4.2.0

[sirosen]

Python Support

• Add support for Python 3.14. (Add support for Python 3.14 #1340)

• Remove support for Python 3.8. (Remove support for Python 3.8 #1341)

Added

• GlobusApp and SDK client classes now support usage as context managers, and
  feature a new close() method to close internal resources.
  close() is automatically called on exit. (Support context manager usage of clients and apps to implicitly close token storage and transports #1326)

  • In support of this, token storages now all feature a close() method,
    which does nothing in the default implementation.
    Previously, only storages with underlying resources to manage featured a
    close() method.

  • GlobusApp will close any token storage via close() if the token storage
    was created by the app on init. Explicitly created storages will not be closed
    and must be explicitly closed via their close() method.

  • Any class inheriting from BaseClient features close(), which will
    close any transport object created during client construction.

  • Transports which are created explicitly will not be closed by their clients,
    and must be explicitly closed.

• Add TimersClient.add_app_flow_user_scope for TimersClient
  instances which are integrated with GlobusApp. This method registers the
  specific flow user scope dependency needed for a flow timer. (Add a TimersClient app scope helper for specific flow user #1333)

• Added automatic Globus Auth Requirements Error (GARE) redriving to GlobusApp
  (Auto-retry gares in a GlobusApp #1339).

  • More details available at :ref:globus_app_gare_integration
  • This feature is disabled by default but can be turned on by setting
    auto_retry_gares=True in a GlobusAppConfig.

Fixed

• Fixed a resource leak in which a GlobusApp would create internal client
  objects and never close the associated transports. (Support context manager usage of clients and apps to implicitly close token storage and transports #1326)

Development

• Added a new make install recipe.
