Línea de trabajo

Comienza con las pruebas Expected-Failure del Coverage-PR y compara sus assertions para DIRECTRES-001 a DIRECTRES-011 con el Reference Driver PR. Rastrea la solicitud nativa SEA ExecuteStatement y el manejo de resultados CLOSED y respuestas de varios chunks. Se considera terminado cuando las pruebas xfail pasan sin un wait_timeout positivo al habilitar los resultados directos, incluidos los casos de cierre redundante y truncamiento.

Descripción

Surfaced by the multi-language coverage fan-out while conformance-testing these SPEC-IDs against databricks/databricks-sql-python.

Each is committed as an expected-failure (xfail) test in the coverage PR — the test asserts the CORRECT behavior and stays red until this driver is fixed.

DIRECTRES-001: native SEA backend sends a positive wait_timeout on ExecuteStatement; ES-2034600 fix omits it when direct results are on
DIRECTRES-002: native SEA backend sends a positive wait_timeout on ExecuteStatement; ES-2034600 fix omits it when direct results are on
DIRECTRES-003: native SEA backend sends a positive wait_timeout on ExecuteStatement; ES-2034600 fix omits it when direct results are on
DIRECTRES-004: native SEA backend sends a positive wait_timeout; the CLOSED-as-success skip-redundant-close contract cannot be conformed (ES-2034600)
DIRECTRES-011: SEA ExecuteStatement sends positive wait_timeout instead of omitting it; multi-chunk result can be silently truncated to chunk 0 under sync-hybrid (ES-2034600)
