  • [nitpick] Consider renaming 'UvloopUvicornWorker' to 'UVLoopUvicornWorker' to clearly indicate the 'UVLoop' acronym using uppercase, aligning with common naming conventions.

Walkthrough

The pull request updates the application's worker configuration. In the Dockerfile, the CMD instruction now references a new worker, switching from using uvicorn.workers.UvicornWorker to src.settings.gunicorn.UvloopUvicornWorker. Additionally, a new class is added in the gunicorn settings file that extends the original worker, preconfiguring it with uvloop through a class-level attribute. These changes adjust the concurrency handling in the application without modifying other command parameters.

Changes

File(s) Change Summary
Dockerfile Updated the CMD instruction to reference src.settings.gunicorn.UvloopUvicornWorker instead of uvicorn.workers.UvicornWorker.
src/settings/gunicorn.py Added a new class UvloopUvicornWorker (extending UvicornWorker) with CONFIG_KWARGS configured as { "loop": "uvloop" }, and an associated import.

Poem

I'm a bouncy bunny, coding with delight,
Hopping into changes under soft moonlight.
A new worker sprouts, swift as a breeze,
With uvloop magic that aims to please.
In the realm of code, I nibble and cheer,
Celebrating each tweak, my joy is clear!

    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

19-19: Remove redundant --loop uvloop parameter.

The worker class UvloopUvicornWorker already configures uvloop through its CONFIG_KWARGS, making the --loop uvloop parameter at the end of the command redundant. Consider removing this parameter to avoid potential conflicts.

3-3: Appropriate import for the worker implementation.

This import is necessary for creating the custom worker class that extends UvicornWorker.


21-22: Good implementation of a custom worker with uvloop.

This is a clean implementation for ensuring uvloop is used. By extending UvicornWorker and setting CONFIG_KWARGS, you're properly configuring uvloop at the class level rather than through command-line arguments.
