fix: handle deleted files in git patch processing and update section header logic

[mrT23]

PR Type

Bug fix, Enhancement

---

Description

• Improved section header logic:
  • Now updates both start and size in a single operation for better efficiency
  • Adjusts extended_start2 and extended_size2 along with their counterparts
• Added handling for deleted files:
  • Checks if the file has an edit_type attribute set to DELETED
  • Returns a message indicating file deletion instead of processing the patch
• Enhanced context limits calculation:
  • Ensures more accurate representation of changes in the patch
• These changes improve the overall robustness and accuracy of git patch processing

⚡ Key issues to review Potential Edge Case The new code for handling deleted files assumes that all file objects have an 'edit_type' attribute. This might cause AttributeError if some file objects don't have this attribute.

PR Code Suggestions ✨

Latest suggestions up to c2f5253

Category	Suggestion	Score
Consistency	Use consistent formatting for file headers in the output Consider using an f-string for the return statement to improve readability and consistency with the rest of the code. pr_agent/algo/git_patch_processing.py [243] -return f"\n\n## file '{file.filename.strip()}' was deleted\n" +return f"\n\n## file: '{file.filename.strip()}' was deleted\n" Apply this suggestion Suggestion importance[1-10]: 8 Why: This suggestion improves consistency with the rest of the code and enhances readability. It's a small but important change for maintaining code quality.	8
Best practice	Use an enum for edit type comparison instead of a string Consider using a constant or an enum for the 'DELETED' edit type instead of a string comparison. This can improve code readability and maintainability. pr_agent/algo/git_patch_processing.py [242] -if hasattr(file, 'edit_type') and file.edit_type == EDIT_TYPE.DELETED: +if hasattr(file, 'edit_type') and file.edit_type == EditType.DELETED: Apply this suggestion Suggestion importance[1-10]: 7 Why: This suggestion improves code maintainability and reduces the risk of errors, but the existing code is already using EDIT_TYPE.DELETED, which appears to be an enum.	7
Enhancement	Use tuple unpacking to update multiple variables in a single line Consider using tuple unpacking to update extended_start1, extended_start2, extended_size1, and extended_size2 in a single line. This can make the code more concise and Pythonic. pr_agent/algo/git_patch_processing.py [89-90] -extended_start1, extended_start2 = extended_start1 + i, extended_start2 + i -extended_size1, extended_size2 = extended_size1 - i, extended_size2 - i +(extended_start1, extended_start2), (extended_size1, extended_size2) = (extended_start1 + i, extended_start2 + i), (extended_size1 - i, extended_size2 - i) Apply this suggestion Suggestion importance[1-10]: 5 Why: The suggestion is valid and can make the code more concise, but it's a minor improvement that doesn't significantly impact functionality or readability.	5

Category	Suggestion	Score
Best practice	Use a more descriptive variable name in the loop to improve code readability Consider using a more descriptive variable name instead of i in the for loop. A name like line_index or header_offset might better convey the purpose of the variable. pr_agent/algo/git_patch_processing.py [85-91] -for i,line, in enumerate(lines_before): +for header_offset, line in enumerate(lines_before): if section_header in line: found_header = True # Update start and size in one line each - extended_start1, extended_start2 = extended_start1 + i, extended_start2 + i - extended_size1, extended_size2 = extended_size1 - i, extended_size2 - i - get_logger().debug(f"Found section header in line {i} before the hunk") + extended_start1, extended_start2 = extended_start1 + header_offset, extended_start2 + header_offset + extended_size1, extended_size2 = extended_size1 - header_offset, extended_size2 - header_offset + get_logger().debug(f"Found section header in line {header_offset} before the hunk") Suggestion importance[1-10]: 7 Why: This suggestion enhances code readability by using a more descriptive variable name, which is a good practice for maintaining clear and understandable code.	7
Enhancement	Combine multiple variable assignments into a single tuple unpacking operation Consider using tuple unpacking to update extended_start1, extended_start2, extended_size1, and extended_size2 in a single line. This can make the code more concise and Pythonic. pr_agent/algo/git_patch_processing.py [89-90] -extended_start1, extended_start2 = extended_start1 + i, extended_start2 + i -extended_size1, extended_size2 = extended_size1 - i, extended_size2 - i +extended_start1, extended_start2, extended_size1, extended_size2 = extended_start1 + i, extended_start2 + i, extended_size1 - i, extended_size2 - i Suggestion importance[1-10]: 5 Why: The suggestion is valid and improves code conciseness, but it's a minor optimization that doesn't significantly impact functionality or readability.	5
