Línea de trabajo

Comienza con la prueba que falla test_get_tables_empty_table_types_filter_matches_all en el PR de cobertura bajo tests/ y luego sigue la ruta Thrift get_tables del conector de Python. Confirma el comportamiento de table_types vacío con respecto al contexto de conformidad enlazado; se considera terminado cuando la prueba pasa y los tipos vacíos coinciden con todos los tipos de tabla.

Descripción

Summary

Surfaced by the multi-language coverage fan-out while conformance-testing these SPEC-IDs against databricks/databricks-sql-python. Each finding is committed as an expected-failure (xfail) test in the coverage PR — the test asserts the CORRECT (post-fix) behavior and stays red until THIS driver (databricks/databricks-sql-python) is fixed, then flips green as a tripwire.

Findings

METADATA-035 [thrift]: Thrift get_tables forwards an empty table_types list verbatim as TGetTablesReq.tableTypes=[], so the server matches no table type and returns 0 rows, instead of treating empty like None (match all) per the hiveserver2 empty-types parity contract; the connector's kernel path already normalises [] to None.
- failing test: test_get_tables_empty_table_types_filter_matches_all (see the coverage PR diff under tests/)

Context

The behavior was first fixed in a DIFFERENT driver — reference PR: https://github.com/databricks/databricks-sql-kernel/pull/183 — which seeded the shared language-neutral spec. This issue tracks the same conformance gap in databricks/databricks-sql-python; the reference PR is for cross-referencing the intended behavior, NOT a change to this repo.
Coverage PR carrying the reproducing xfail test(s): https://github.com/databricks/databricks-driver-test/pull/1021
