Walkthrough

The StartCommand class now employs both head and tail commands to capture and log output more comprehensively. This dual-command approach ensures that both the beginning and end of the output are monitored, providing a fuller picture of the process's execution status.

Changes

File	Change Summary
.../start.js	Modified to use head and tail for output capturing. Adjusted logging to include both outputs with an ellipsis for continuity.

🐇✨
In the land of code, where the rabbits hop,
A change was made, oh what a swap!
Head and tail, both in play,
Capturing logs, night and day.
Celebrate we shall, with a carrot top! 🥕

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>.
  • 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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @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.

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.

CodeRabbit Commands (invoked as PR comments)

Optimize error log retrieval and improve logging structure.

- const [ headStdout ] = await execFile('head', args);
- const [ tailStdout ] = await execFile('tail', args);
- this.logger.error('Got error when startup: ');
- this.logger.error(headStdout);
- this.logger.error('...');
- this.logger.error(tailStdout);
+ const [ combinedStdout ] = await execFile('sh', ['-c', `head ${args.join(' ')} && echo '...' && tail ${args.join(' ')}`]);
+ this.logger.error('Startup error log:\\n%s', combinedStdout);

This change combines the head and tail commands into a single shell command, reducing the number of file reads. Additionally, it structures the error log into a single message, making it clearer and more concise.
