[coverage] Conformance findings: ERRORRECOV-014

[peco-engineer-bot]

Summary

Surfaced by the multi-language coverage fan-out while conformance-testing these SPEC-IDs against databricks/databricks-sql-nodejs. 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-nodejs) is fixed, then flips green as a tripwire.

Findings

• ERRORRECOV-014 [sea]: SEA: retryDelayMax < retryDelayMin is passed to the kernel unvalidated and trips a Rust assertion failed: min <= max, surfacing as Error: panic in native binding and killing the tokio worker — an inconsistent backoff-bound pair must be corrected (raise max to min) and warn, not take the connection down
  • failing test: Errors — RetryBackoffBounds > retryDelayMax below retryDelayMin — connection opens and the retried query still succeeds [xfail] [sea] (see the coverage PR diff under tests/)

Reproduce & Expected

ERRORRECOV-014 — Validate that a backoff-bound typo — a configured MAXIMUM wait below the configured MINIMUM — does NOT fail the connection.

Reproduce:

SELECT 1 AS test_value

Expected (per the shared spec):

• completes without an exception
• result has exactly 1 row(s)
• full assertion contract:

result:
- connection_not_null: true
  description: "max < min is corrected, not rejected \u2014 the connection opens"
- no_exception: true
- row_count: 1
  description: The retried query still succeeds under the corrected policy
protocol:
  thrift:
  - call_min:
      method: ExecuteStatement
      min: 2
  sea:
  - call_min:
      operation: ExecuteStatement
      min: 2

Context

• The behavior was first fixed in a DIFFERENT driver — reference PR: https://github.com/databricks/databricks-odbc/pull/181 — which seeded the shared language-neutral spec. This issue tracks the same conformance gap in databricks/databricks-sql-nodejs; 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/1110
