🐛 bug: Fix missing Allow header in EnvVar middleware per RFC 9110#3570
🐛 bug: Fix missing Allow header in EnvVar middleware per RFC 9110#3570ReneWerner87 merged 3 commits intomainfrom
Conversation
WalkthroughThe middleware for handling environment variable requests was updated to allow both GET and HEAD HTTP methods. When a disallowed method is used, the "Allow: GET, HEAD" HTTP header is set before returning a 405 Method Not Allowed response. Tests were added and enhanced to verify correct handling of HEAD requests and the Allow header. Changes

Summary of Changes
Hello @gaby, 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 improves the HTTP compliance of the envvar middleware by ensuring that 405 (Method Not Allowed) responses include the appropriate Allow header. It also updates the test suite to validate this new behavior, making the middleware more robust and standards-compliant.
Highlights
- HTTP Compliance: The
envvarmiddleware now correctly sets theAllow: GETheader in 405 Method Not Allowed responses, ensuring better adherence to HTTP specifications. - Test Coverage: A new assertion has been added to the
envvarmiddleware tests to verify that theAllowheader is properly set toGETwhen a 405 response is returned.

Code Review
This pull request correctly adds the Allow header to 405 responses in the envvar middleware, which is a good fix for HTTP compliance. The new test case properly verifies this behavior. I've added one suggestion to also support HEAD requests, which is a common convention for GET endpoints and aligns better with Fiber's default behavior, along with a corresponding test update.
