Summary of Changes

Hello @eriksjolund, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request streamlines the error handling within the libcrun library by eliminating a superfluous check on the return value of xasprintf(). The xasprintf() function is typically implemented to manage its own allocation failures, meaning the explicit check for a negative return value was redundant. This change results in cleaner and more concise code without altering the functional behavior.

Highlights

• Code Cleanup: Removed an unnecessary error check for the xasprintf() function call in src/libcrun/linux.c.
• Error Handling: The xasprintf() function is designed to handle allocation failures internally, making an explicit return value check redundant and improving code clarity.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

• src/libcrun/linux.c
  • Removed the if (UNLIKELY (ret < 0)) condition that checked the return value of xasprintf() when assigning to private_data->maskdir_proc_path.

Code Review

This pull request correctly removes an unnecessary check on the return value of xasprintf. Following the convention of other x prefixed functions in this codebase (like xmalloc), xasprintf is designed to terminate the program on memory allocation failure rather than returning an error code. This makes the check for a negative return value unreachable. The change simplifies the code and improves clarity by removing this redundant check. The modification is sound and I approve of it.

Indeed, xasprintf never returns a negative value.
