🔍 Pull Request Review: Update actions/setup-go to v6

📊 Overall Assessment: ⚠️ NEEDS ATTENTION

This is a Renovate-generated dependency update that requires manual review due to a critical configuration issue.

🐛 CRITICAL ISSUE IDENTIFIED

Go Version 1.25 Does Not Exist: The CI workflow is configured with go-version: '1.25', but Go 1.25 has not been released yet. As of September 2025, the latest Go version is 1.23.x series.

Impact: This will cause the CI pipeline to fail when actions/setup-go@v6 tries to install a non-existent Go version.

🔧 Required Fix

Update .github/workflows/ci.yml line 151 to use a valid Go version:

- name: Setup Go (for Go tools testing)
  uses: actions/setup-go@v6
  with:
    go-version: '1.23'  # or '1.22' for LTS

✅ What's Good

1. Dependency Management: Renovate is correctly maintaining GitHub Actions dependencies
2. Minimal Change: Single line update keeps the change scope focused
3. Semantic Versioning: Update follows proper major version increment (v5 → v6)

🔍 actions/setup-go v6 Analysis

Pros:

• Likely includes bug fixes and security improvements
• Better Node.js runtime support (newer versions)
• Enhanced caching mechanisms

Potential Concerns:

• Major version updates may include breaking changes
• Need to verify compatibility with the specified Go version format

🧪 Testing Recommendations

Before merging:

1. Fix the Go version configuration
2. Test the integration job manually to ensure Go tools installation works
3. Verify that golangci-lint and staticcheck still install correctly

🛡️ Security Assessment

✅ LOW RISK: This is a standard GitHub Actions update from a trusted source (actions organization).

📋 Action Items

• REQUIRED: Fix Go version from 1.25 to 1.23 (or appropriate version)
• Verify CI pipeline passes after the fix
• Consider pinning to a stable Go version for consistency

💡 Recommendation

DO NOT MERGE until the Go version issue is resolved. Once fixed, this is a safe and recommended update.

🔍 PR Review: Update actions/setup-go from v5 to v6

Thank you for this dependency update PR from Renovate. I've reviewed the changes and have the following feedback:

✅ Code Quality & Best Practices

• The change is minimal and follows GitHub Actions best practices
• Single line change upgrading a well-maintained action to its latest major version
• Properly scoped to the integration test job where Go is needed

⚠️ Critical Issue: Invalid Go Version

The workflow specifies go-version: '1.25' which does not exist. Go versions currently only go up to 1.23 (as of late 2024). This will cause the workflow to fail.

Required Fix:

- go-version: '1.25'
+ go-version: '1.23'  # or '1.22' for more stability

📋 Additional Recommendations

1. Version Consistency: Consider using the same Go version strategy as Node.js with a matrix to test multiple versions:

   strategy:
     matrix:
       go-version: ['1.21', '1.22', '1.23']

2. Cache Go Modules: The setup-go@v6 action supports Go module caching. Add:

   - uses: actions/setup-go@v6
     with:
       go-version: '1.23'
       cache: true
       cache-dependency-path: test-go-project/go.sum

3. Action Pinning: For better security and reproducibility, consider pinning to a specific SHA:

   uses: actions/setup-go@0a12ed9d6a96ab950c8f026ed9f722fe0da7ef32  # v6.0.0

✅ Performance Considerations

• No performance impact expected from this upgrade
• v6 includes performance improvements for Go module caching

✅ Security Assessment

• actions/setup-go is an official GitHub Action with good security practices
• v6 includes security updates and improvements
• No security concerns with this upgrade

✅ Test Coverage

• The integration test properly validates Go tool functionality across multiple OS platforms
• Tests create a sample Go project and verify tool integration

📝 Summary

This is a good dependency update, but the PR cannot be merged until the Go version issue is fixed. The workflow will fail with the non-existent Go version '1.25'.

Please update the Go version to a valid release (1.21, 1.22, or 1.23) before merging.
