Revisit Spec Compliance on Retryable Writes

    • 5
    • Not Needed

      Use Case

      As a developers
      I want the driver to retry writes according to the specification
      So that the driver behaves as expected.

      The driver currently determines if a write is retryable by only looking at the error code. The retryable writes specification states which error codes are retryable but that the driver MUST retry any write when the error has the "RetryableWriteError" label. From server 4.4 the server adds the label itself so that must be the source of truth, not the error code.

        -Re-enable the currently skipped tests.
        -Limit scope to 4.x driver unless it is a straight forward port to 3.x.
