  • The test results, such as pasting the results comparison before and after, or e2e results
  • (Optional) The necessary documentation update, such as updating supported_models.md and examples for a new model.

👋 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 @draftbk, 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 refines the automated labeling system by updating the Mergify configuration. My aim is to ensure that all pull requests touching files relevant to speculative decoding, including new module versions, examples, and specific model implementations, are consistently and automatically tagged with the appropriate label for better organization and tracking.

Highlights

  • Automation Rule Expansion: I have expanded the conditions for automatically applying the 'speculative-decoding' label to pull requests within the .github/mergify.yml configuration.
  • Comprehensive File Pattern Inclusion: The updated rule now includes a broader set of file paths and patterns. This covers new v1 directories for speculative decoding, various example scripts (e.g., spec_decode, mlpspeculator, eagle, speculation), and specific model/config files related to eagle, mlp_speculator, and medusa.

Code Review

This pull request adds new rules to .github/mergify.yml to automatically label pull requests related to speculative decoding. I have a couple of suggestions to improve the maintainability and correctness of the new rules.

The regular expressions for eagle.py and medusa.py config files are not anchored with ^. This could lead to incorrect matches for file paths that contain these strings but are not the exact files intended. Since these are exact file paths, it's better and safer to use the = operator for an exact match, just as you did for mlp_speculator.py on line 171.

      - files=vllm/transformers_utils/configs/eagle.py
      - files=vllm/transformers_utils/configs/medusa.py

These four patterns for matching example files are a bit redundant and can be combined into a single, more concise regular expression. This will improve the readability and maintainability of the configuration file.

      - files~=^examples/.*(spec_decode|mlpspeculator|eagle|speculation).*\.py
