Summary of Changes

Hello @ReneWerner87, 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 introduces a crucial update to the v3 migration script for the cache middleware. It addresses a breaking change where the CacheControl configuration field was renamed to DisableCacheControl and its semantic meaning inverted. The changes ensure that existing configurations are automatically and correctly transformed, preventing issues for users upgrading to the new version. The inclusion of comprehensive tests guarantees the reliability and idempotency of this migration process.

Highlights

  • Cache Middleware Migration Update: The migration script for cache.Config has been updated to handle the rename of the CacheControl field to DisableCacheControl. This involves inverting the boolean logic during the conversion.
  • Robust Migration Logic: The migration now correctly processes various forms of boolean expressions for CacheControl, including true, false, direct variable references, and negated expressions (e.g., !cfg.DisableCacheHeaders).
  • Comprehensive Migration Tests: New tests have been added to verify the migration's correctness for literal boolean values and complex expressions, as well as to ensure the migration is idempotent, meaning it can be run multiple times without unintended side effects.

Code Review

This pull request adds a migration script to rename CacheControl to DisableCacheControl with inverted semantics. The implementation is mostly correct and includes good test coverage. However, I've found a potential bug in the regex-based replacement logic where it doesn't correctly handle comments, which could lead to syntax errors in the migrated code. I've provided a suggestion to fix this and also recommended enhancing the tests to cover these edge cases. Overall, a good contribution that will be solid after addressing the feedback.
