调研方向

从 tests/ 下 coverage PR diff 中的 TestTelemetryEnablementPropertyIsHonoredAndOptional 开始,然后追踪 Go 驱动程序的 DSN 解析以及连接时对 telemetry 属性的处理。确认驱动程序自身对 EnableTelemetry 的拼写。完成的标准是:格式错误的值允许连接打开,保留默认值,并产生指定的警告诊断;同时,有效值和缺失值仍能正常工作。

描述

Summary

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

Findings

  • SESSION-017 [thrift]: A malformed enableTelemetry DSN value is fatal: ParseDSN rejects the entire DSN (strconv.ParseBool error) so the connection never opens, instead of leaving the telemetry overlay default untouched and diagnosing the typo
    • failing test: TestTelemetryEnablementPropertyIsHonoredAndOptional (see the coverage PR diff under tests/)

Reproduce & Expected

SESSION-017 — Validates the connect-time contract of the driver's telemetry-enablement connection property (reference ODBC key EnableTelemetry; map to the driver's own spelling for the SAME concept, e.g.

Reproduce:

SELECT 1 AS value
SELECT 1 AS value
SELECT 1 AS value
SELECT 1 AS value

Expected (per the shared spec):

  • completes without an exception
  • result has exactly 1 row(s)
  • col 0 is named value
  • completes without an exception
  • result has exactly 1 row(s)
  • completes without an exception
  • result has exactly 1 row(s)
  • completes without an exception
  • result has exactly 1 row(s)
  • full assertion contract:
result:
- label: opt_in
  no_exception: true
- label: opt_in
  row_count: 1
- label: opt_in
  column:
    index: 0
    name: value
- label: opt_in
  warning_diagnostic:
