PatchPro Bot Example

This directory contains example files and data for testing the PatchPro bot.

Structure

• src/ - Example Python files with various code issues
• artifact/analysis/ - Sample JSON output from Ruff and Semgrep analyzers

Sample Issues

The example files contain various types of issues that PatchPro can detect and fix:

Security Issues (Semgrep)

• Shell Injection (CWE-78): Using subprocess.call() with shell=True
• Weak Cryptography (CWE-327): Using MD5 hash algorithm
• Exception Handling: Catching broad exceptions before specific ones

Code Quality Issues (Ruff)

• F401: Unused imports
• F841: Unused variables
• E501: Line too long
• B007: Loop control variable not used

Running the Example

To test the PatchPro bot with this example:

1. Set your OpenAI API key:

   export OPENAI_API_KEY="your-api-key-here"

2. Run the agent core:

   cd examples
   python -m patchpro_bot.agent_core

Or use the example as a test case in your development workflow.

Expected Output

The bot should generate:

• Unified diff patches for each file
• A comprehensive report in artifact/report.md
• Individual or combined patch files in artifact/

File Descriptions

src/example.py

Main example file containing:

• Unused import (os)
• Long line (E501)
• Security vulnerability (shell injection)
• Insecure hash usage

src/utils.py

Utility functions with:

• Unused variables
• Loop control issues
• Bad exception handling order
• More security issues

Analysis Files

• ruff_output.json: Sample Ruff analyzer output
• semgrep_output.json: Sample Semgrep analyzer output

These JSON files represent what would typically be generated by running:

ruff check --output-format json examples/src/ > artifact/analysis/ruff_output.json
semgrep --config=auto --json examples/src/ > artifact/analysis/semgrep_output.json
