👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

Summary of Changes

Hello @yewentao256, 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 focuses on improving code maintainability and reducing redundancy by consolidating the logic for finding an open network port. It eliminates a duplicate utility function, ensuring that a single, standardized approach is used across the codebase for this common task.

Highlights

• Refactoring: I've removed a duplicate find_free_port utility function from vllm/model_executor/layers/fused_moe/utils.py.
• Code Standardization: All call sites that previously used the removed function now correctly utilize the canonical get_open_port function from vllm.utils.

Looks like the utils function is the same behavior but objectively better
