Summary of Changes

Hello @guglielmo-san, 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 resolves an issue in the request handling mechanism where user information was not consistently carried over when a new server call context was instantiated. By explicitly passing the user object during context creation, the fix prevents data loss and ensures that user-specific data remains available for subsequent operations within the request.

Highlights

  • Bug Fix: User Context Loss: Addresses a bug where the user parameter within the ServerCallContext was inadvertently deleted or lost when a new ServerCallContext was created, specifically when the request included requested extensions.
  • Context Propagation: Ensures that the user property from the original ServerCallContext is correctly propagated and copied to any newly created ServerCallContext instances, maintaining user context throughout the request lifecycle.

Code Review

This pull request addresses a bug where the user property was lost from the ServerCallContext when requested extensions were present. The changes correctly fix this issue by ensuring the user is preserved in two scenarios:

  1. When a new ServerCallContext is created, the user from the original context is now correctly passed along.
  2. The newServerCallContext is now initialized with the original context, which prevents the user from being dropped if no extensions are requested but a context with a user exists.

The fix is direct, easy to understand, and correctly resolves the bug. I've added one suggestion to include a regression test to ensure this bug doesn't reappear in the future.
