Description

• Added robust error handling for line extraction from git patches with try-except blocks and detailed error logging
• Implemented fallback mechanism to extract lines from patch when file content is missing
• Improved code reliability by filtering out deleted lines and handling edge cases
• Enhanced debugging capabilities with detailed error messages and tracebacks
• Added documentation and improved code structure

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add validation for regex match results before processing to prevent potential runtime errors Add validation for empty or None values in the match variable before calling extract_hunk_headers(). The current code assumes the regex match is successful but could fail if the hunk header is malformed. pr_agent/algo/git_patch_processing.py [385-387] match = RE_HUNK_HEADER.match(line) +if not match: + get_logger().error(f"Failed to parse hunk header: {line}") + continue section_header, size1, size2, start1, start2 = extract_hunk_headers(match) Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion addresses a critical error handling case that could cause runtime errors if the hunk header is malformed. Adding validation before processing the match result improves code robustness.	8
	Validate patch content existence before processing to prevent potential errors Add validation for empty or malformed patch content before attempting to extract lines from it in the fallback mechanism. pr_agent/algo/utils.py [289-291] patch = file.patch +if not patch: + get_logger().error(f"No content or patch found in file: '{file.filename}'") + return "" get_logger().info(f"No content found in file: '{file.filename}' for 'extract_relevant_lines_str'. Using patch instead") _, selected_lines = extract_hunk_lines_from_patch(patch, file.filename, start_line, end_line,side='right') Apply this suggestion Suggestion importance[1-10]: 7 Why: The suggestion adds important null/empty check for patch content before processing, preventing potential errors in the fallback mechanism. This validation improves error handling and code reliability.	7
	Add length validation before string slicing to prevent index errors When filtering out deleted lines from the patch, ensure the line has content before accessing index [1:] to avoid index out of range errors. pr_agent/algo/utils.py [297-300] for line in selected_lines.splitlines(): if line.startswith('-'): continue - relevant_lines_str += line[1:] + '\n' + if len(line) > 0: + relevant_lines_str += line[1:] + '\n' + else: + relevant_lines_str += '\n' Apply this suggestion Suggestion importance[1-10]: 6 Why: The suggestion prevents potential index out of range errors when handling empty lines in the patch content. While not a critical issue, it improves code robustness by handling edge cases.	6

/help "Is the Gemini Flash 2.0 model supported using Google AI Studio?"

[qodo-merge-pro-for-open-source]

Question:

Is the Gemini Flash 2.0 model supported using Google AI Studio?

Answer:

Yes, Google AI Studio models including Gemini-1.5-flash can be used with Qodo Merge. To use it, you need to:

1. Set the model configuration in your configuration.toml file:

[config]
model="google_ai_studio/gemini-1.5-flash"
fallback_models=["google_ai_studio/gemini-1.5-flash"]

2. Set your Google AI Studio API key either in .secrets.toml:

[google_ai_studio]
gemini_api_key = "..."

Or as an environment variable: GOOGLE_AI_STUDIO.GEMINI_API_KEY
