Summary of Changes

Hello @olavloite, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a critical bug where the DecodeToNativeArrays setting, when provided via the ConnectorConfig, was not being properly propagated to the underlying database connection. This fix ensures that connections correctly honor this configuration, improving data type handling. Additionally, the changes include an updated test suite to validate the correct application of this setting, enhancing the robustness of the driver.

Highlights

• Bug Fix: DecodeToNativeArrays: The DecodeToNativeArrays option specified in ConnectorConfig is now correctly copied to the initial connection state, resolving an issue where this setting was previously ignored.
• Test Coverage: An existing test case (TestQueryWithAllNativeTypes) has been enhanced to explicitly verify that DecodeToNativeArrays is correctly applied when configured through ConnectorConfig, alongside the existing parameter-based configuration.

Code Review

This pull request correctly fixes an issue where the DecodeToNativeArrays option in ConnectorConfig was being ignored. The change in driver.go ensures this option is properly copied to the initial connection state, consistent with other connector configuration properties. The accompanying update to driver_with_mockserver_test.go is excellent, refactoring the test to cover both setting the option via ConnectorConfig and through connection string parameters. This ensures the fix is robust and well-tested. The changes are clean, correct, and improve the driver's reliability.
