Walkthrough

This update introduces a workaround in the entrypoint.sh script for both Melodic and Noetic ROS distributions to address issues related to Docker image creation using "docker commit." The solution checks and removes specific lock files that could interfere with the process, ensuring smoother execution of the script.

Changes

Files Change Summary
melodic/entrypoint.sh Added checks and removal for lock files to avoid issues during Docker image creation.
noetic/entrypoint.sh Implemented a similar workaround for Docker image creation, targeting specific temporary lock files for cleanup.

Poem

In a script our code did weave,
A fix for Docker we did achieve.
Locks removed, errors ceased,
Our containers now run like a breeze.
Hopping forward, changes made,
In code’s garden, progress laid. 🌸🐇


Tip

Early access features: enabled

We are currently testing the following features in early access:

  • OpenAI gpt-4o model for code reviews and chat: OpenAI claims that this model is better at understanding and generating code than the previous models. We seek your feedback over the next few weeks before making it generally available.

Note:

  • You can enable or disable early access features from the CodeRabbit UI or by updating the CodeRabbit configuration file.
  • Please join our Discord Community to provide feedback and report issues.
  • OSS projects are always opted into early access features.

Thank you for using CodeRabbit. We offer it for free to the OSS community and would appreciate your support in helping us grow. If you find it useful, would you consider giving us a shout-out on your favorite social media?

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.
    • @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.
