Summary of Changes

Hello @deepdring, 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 refactors existing Go test code by eliminating unnecessary variable reassignments within for loops. This change aligns the codebase with recent Go language optimizations, where explicit reassignments of loop variables (e.g., tt := tt) are no longer required to ensure correct behavior with closures. The refactoring improves code readability and maintains functionality without altering the logic of the tests.

Highlights

• Code Refactoring: The pull request refactors Go test files by removing redundant variable reassignments within for loops. This change leverages optimizations in newer Go versions where such reassignments are no longer necessary to prevent issues with loop variable capture in closures.

Code Review

This pull request refactors Go tests to remove the tt := tt variable shadowing, which is a good cleanup for projects using Go 1.22 or newer. The change correctly identifies an outdated pattern. However, this refactoring introduces a critical dependency on Go 1.22+. Without an accompanying update to the go.mod file to enforce this Go version, the parallel tests will be subject to race conditions and will likely fail or produce incorrect results when run with older Go versions. My review includes a critical comment to address this potential issue by ensuring the Go version is updated.

[gemini-code-assist]

Removing the tt := tt shadowing is only safe if the project's Go version is 1.22 or higher. This change relies on the new loop variable semantics introduced in Go 1.22. If the project is compiled with an older Go version, this will introduce a race condition in these parallel tests, causing them to behave incorrectly and fail unpredictably.

Recommendation:
To prevent this critical issue, the go.mod file must be updated to go 1.22 or newer as part of this pull request. If updating the Go version is not possible, this change should be reverted.
