Summary of Changes
Hello @akitaSummer, 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 addresses a compatibility issue with HTTP redirection handling in urllib when operating within a Node.js 18 environment. It introduces a targeted configuration that delegates the responsibility of managing redirects to undici's built-in capabilities, thereby ensuring proper request flow and preventing potential errors. The changes are validated by a new dedicated test case.
Highlights
- Node.js 18 Redirection Compatibility: Implemented a specific workaround for HTTP redirection handling when running on Node.js 18. This involves explicitly disabling
urllib's internal redirection logic and instead configuringundici's global dispatcher with a redirect interceptor to manage redirections. - New Dependency: Added
undicias a direct dependency to facilitate the new redirection handling mechanism for Node.js 18 environments. - Test Coverage: Introduced a new test case to verify that
maxRedirectionsfunctions correctly and does not throw errors when running on Node.js 18, ensuring the fix behaves as expected.

Code Review
This pull request addresses a compatibility issue with urllib on Node.js 18 by using undici for handling redirects. The implementation modifies a global state on every request, which could lead to performance problems and memory leaks. A fix has been suggested. Additionally, improvements to the test suite have been recommended to ensure the redirection logic is more thoroughly verified.
