As revealed in the pre-release tests, db-dtypes is incompatible with the upcoming pandas 3.1 release. This PR fixes the gaps:

  • 79c3640: remove references to an internal, removed variable
  • 3fd5190: added required _cast_pointwise_result implementation to BaseDatetimeArray
  • b954d7a added required _cast_pointwise_result and _from_pyarrow_array implementations to JSONArray
  • 4a11a99: added (and marked as skip or xfail, if not relevant to the types) new compliance test cases

Code Review

This pull request prepares the codebase for pandas 3.1.0 compatibility by implementing _cast_pointwise_result and _from_pyarrow_array methods, removing the pandas version constraint, and updating compliance tests with necessary xfail and skip markers. The reviewer feedback suggests calling _from_sequence via type(self) in json.py for idiomatic consistency, and simplifying the NumPy version checks in the compliance tests to use a dependency-free string split instead of importing packaging.version.
