Walkthrough

The changes in this pull request primarily involve modifications to the Server struct and its methods in the udp/server/server.go file. The responseMsgCache field has been removed, along with its initialization in the New constructor. Additionally, the call to check for expired messages in the Serve method has been eliminated, simplifying the server's operational logic while maintaining existing error handling and connection management functionalities.

🐇 "In the server's heart, a change took place,
The cache is gone, a simpler space.
Requests flow freely, no checks to delay,
Just pure connection, come what may!
Hopping along, we embrace the new,
A streamlined path, for me and you!" 🐇

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • 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.
