Summary of Changes

Hello @MalumaDev, 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 addresses a UnicodeDecodeError that can occur when subprocess commands return output containing characters not decodable by the default 'utf-8' codec, particularly in Windows environments. The fix implements a robust handling mechanism for such decoding errors by replacing problematic characters, thereby improving the stability of command execution.

Highlights

• Subprocess Output Decoding: Modified sky/utils/cluster_utils.py to include errors='replace' in a subprocess.run call within the _get_windows_userprofile_via_cmd() function. This change ensures that any non-UTF-8 characters in the command's output are gracefully handled by being replaced, preventing UnicodeDecodeError.

🧠 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

• sky/utils/cluster_utils.py
  • Added errors='replace' to the subprocess.run call in _get_windows_userprofile_via_cmd() to prevent UnicodeDecodeError when processing command output.

Activity

• The pull request was created by MalumaDev to fix an issue related to subprocess output decoding, as referenced in issue UnicodeDecodeError when running under WSL #8791.

Code Review

This pull request addresses a UnicodeDecodeError that occurs when running sky check on Windows Subsystem for Linux (WSL). The crash is caused by non-UTF-8 characters in the output of a subprocess that retrieves the user's home directory. The proposed fix adds errors='replace' to the subprocess.run call, which prevents the crash by replacing invalid characters. While this is a valid approach, I've suggested an improvement to use errors='surrogateescape' instead. This is a more robust method for handling arbitrary byte sequences, especially for file paths, as it avoids data loss and reduces the risk of invalidating the path.
