PR Type

Enhancement, Bug fix

---

Description

• Added error handling for empty diff files in utils.py to prevent processing on an empty list
• Optimized file content retrieval in the Bitbucket provider:
  • Implemented a limit on the number of files for which full content is retrieved
  • Added a counter to track the number of valid files processed
  • Limited full content retrieval to half of MAX_FILES_ALLOWED_FULL to conserve API calls
• Imported MAX_FILES_ALLOWED_FULL constant from git_provider module for consistency
• Improved logging to inform when the file limit is reached and full content retrieval is stopped

PR Code Suggestions ✨

Category	Suggestion	Score
Enhancement	Add logging for empty diff_files list to improve debugging Consider adding a log message or raising a custom exception when an empty diff_files list is encountered. This can help with debugging and provide more context about why no position was found. pr_agent/algo/utils.py [784-785] if not diff_files: + get_logger().warning("Empty diff_files list encountered in find_line_number_of_relevant_line_in_file") return position, absolute_position Apply this suggestion Suggestion importance[1-10]: 7 Why: The suggestion improves error handling and debugging by adding a log message for an empty diff_files list, which is a valid enhancement to the existing code.	7
Best practice	Use a named constant for the division factor to improve code maintainability Consider using a constant or configuration value for the division factor (2) used in the condition. This would make the code more maintainable and easier to adjust if needed. pr_agent/git_providers/bitbucket_provider.py [210] -if counter_valid < MAX_FILES_ALLOWED_FULL // 2: # factor 2 because bitbucket has limited API calls +BITBUCKET_API_LIMIT_FACTOR = 2 # Bitbucket has limited API calls +if counter_valid < MAX_FILES_ALLOWED_FULL // BITBUCKET_API_LIMIT_FACTOR: Apply this suggestion Suggestion importance[1-10]: 6 Why: The suggestion improves code maintainability by introducing a named constant for the division factor, making the code more readable and easier to modify in the future.	6
Maintainability	Use a more descriptive variable name to improve code readability Consider using a more descriptive variable name instead of counter_valid. A name like processed_valid_files might better convey the purpose of this counter. pr_agent/git_providers/bitbucket_provider.py [201-209] -counter_valid = 0 +processed_valid_files = 0 for index, diff in enumerate(diffs): file_path = _gef_filename(diff) if not is_valid_file(file_path): invalid_files_names.append(file_path) continue try: - counter_valid += 1 + processed_valid_files += 1 Apply this suggestion Suggestion importance[1-10]: 6 Why: The suggestion improves code readability by using a more descriptive variable name, which is a good practice for maintaining clear and understandable code.	6
Performance	Optimize loop structure to avoid redundant condition checks The code block for handling the case when counter_valid == MAX_FILES_ALLOWED_FULL // 2 could be moved outside the loop for better performance, as it only needs to be executed once. pr_agent/git_providers/bitbucket_provider.py [221-225] -if counter_valid == MAX_FILES_ALLOWED_FULL // 2: - get_logger().info( - f"Bitbucket too many files in PR, will avoid loading full content for rest of files") +if counter_valid >= MAX_FILES_ALLOWED_FULL // 2: + if counter_valid == MAX_FILES_ALLOWED_FULL // 2: + get_logger().info( + f"Bitbucket too many files in PR, will avoid loading full content for rest of files") + original_file_content_str = "" + new_file_content_str = "" Apply this suggestion Suggestion importance[1-10]: 5 Why: While the suggestion aims to improve performance, the proposed change might make the code less readable. The performance gain is likely minimal, so a moderate score is appropriate.	5
