PR Feedback

• 💡 General suggestions: The changes in the PR seem to be addressing a specific issue related to handling of None values. However, it would be beneficial to add some comments in the code explaining why these checks are necessary and what kind of issues they are solving. This would help other developers understand the context and the reason for these changes.

• 🤖 Code feedback:

  • relevant file: pr_agent/algo/git_patch_processing.py
    suggestion: Consider replacing the for loop used for replacing None values with a list comprehension. This would make the code more concise and Pythonic. [medium]
    relevant line: for i in range(len(res)):

  • relevant file: pr_agent/algo/git_patch_processing.py
    suggestion: It would be better to handle the exception more specifically rather than using a general except clause. This would help in identifying and handling specific issues that might arise. [important]
