abseil/abseil-py v2.1.0

on GitHub

Added

• (flags) Added absl.flags.override_value function to provide FlagHolder with a construct to modify values. The new interface parallels absl.flags.FlagValues.__setattr__ but checks that the provided value conforms to the flag's expected type.
• (testing) Added a new method absltest.TestCase.assertDataclassEqual that tests equality of dataclass.dataclass objects with better error messages when the assert fails.

Changed

• (flags) absl.flags.argparse_flags.ArgumentParser now correctly inherits an empty instance of FlagValues to ensure that absl flags, such as --flagfile, --undefok are supported.
• (testing) Do not exit 5 if tests were skipped on Python 3.12. This follows the CPython change in python/cpython#113856.

Fixed

• (flags) The flag foo no longer retains the value bar after FLAGS.foo = bar fails due to a validation error.
• (testing) Fixed an issue caused by this Python 3.12.1 change where the test reporter crashes when all tests are skipped.
