This PR significantly improves the robustness of the call_python_script function in docker_tool.py. It introduces comprehensive error handling for Docker image pulls, script execution failures, and container management, preventing silent failures and providing clear, actionable error messages.
Problem Solved
Previously, the function could fail silently or crash without informative output under several common error conditions:
Failure to pull the python:3.11 Docker image.
Syntax errors or runtime exceptions within the user-provided script.
Docker API errors during container creation or execution.
This lack of feedback made debugging difficult and the tool less reliable.
Changes Implemented
Hardened Docker Image Pull: Wrapped the images.pull() call in a try...except block to gracefully handle API errors.
Exit Code Verification: The function now checks the exit_code of the script execution. Non-zero codes are now correctly reported as errors.
Robust Container Lifecycle: The entire Docker operation is now within a try...finally block to ensure containers are reliably cleaned up, even in case of an error.
This contribution enhances the tool's stability and provides a much-improved developer experience.
