Walkthrough

The pull request introduces enhancements to signal handling and diagnostic capabilities in the server application. The changes focus on two primary components: the main server configuration and a utility function for goroutine stack trace dumping.

In the main-server.go file, a new signal handler for SIGUSR1 is implemented, allowing the application to dump goroutine stack traces on demand. This provides developers with a mechanism to capture runtime diagnostic information without interrupting the application's core functionality.

Simultaneously, the existing shutdown signal handling mechanism has been improved with additional error recovery capabilities. A deferred panic handler is added to ensure that unexpected errors during the shutdown process do not cause the entire application to crash.

The accompanying utility function DumpGoRoutineStacks() in the utilfn package enables capturing and printing stack traces of all active goroutines, which can be crucial for debugging complex concurrent systems.

🪧 Tips

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.
