📝 Walkthrough

Walkthrough

The update introduces enhanced error handling in the main function. A deferred function now handles panics by using recover() along with the runtime/debug package to print a stack trace on standard error before exiting. Additionally, errors from NewRootCmd() and svrcmd.Execute are now captured and reported with descriptive messages and an exit status of 1. No public or exported declarations were modified.

Changes

File(s)	Change Summary
cmd/.../main.go	Added a deferred panic recovery mechanism using recover() and runtime/debug to print stack traces; enhanced error messaging for NewRootCmd() and svrcmd.Execute calls.

    participant M as Main Function
    participant C as NewRootCmd Creator
    participant E as Execution Handler
    participant D as Deferred Recovery

    M->>D: Setup deferred recovery (recover)
    M->>C: Call NewRootCmd()
    alt Command creation error
        C-->>M: Return error
        M->>M: Print descriptive error message
        M->>S: Exit with status 1
    else
        C-->>M: Return valid command
        M->>E: Call svrcmd.Execute
        alt Execution error
            E-->>M: Return error
            M->>M: Print "Execution error: %v\n" message
            M->>S: Exit with status 1
        else
            note over M,E: Continue normal execution
        end

Poem

I'm a bouncing bunny of code delight,
Hopping 'round errors in the dead of night.
Panic caught with a gentle recover,
Stack traces printed, problems to uncover.
With each fixed bug, my heart takes flight!
🐇 Happy hops in every byte!

cmd/initiad/main.go (5)

4-6: Great addition of necessary imports for error handling.

These imports support the enhanced error management capabilities being added. The runtime/debug package is particularly useful for obtaining stack traces during panic recovery.

---

8-11: Good import organization and inclusion of required packages.

The imports are well-organized and include necessary packages for the improved error handling implementation.

---

15-25: Excellent panic recovery implementation.

This deferred function is a robust safety net that will catch unexpected panics, print useful diagnostic information including the stack trace, and exit gracefully. This significantly improves application stability and debuggability.

---

27-31: Proper error handling for NewRootCmd().

Previously, errors from NewRootCmd() were ignored. This change appropriately captures and handles potential errors during command initialization, preventing the application from continuing in an invalid state.

---

33-40: Enhanced error reporting for command execution.

The improved error formatting provides clearer context with the "Execution error" prefix and uses the command's designated error output stream. This makes troubleshooting easier for users and developers.

🪧 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.
