Refactor GitHub RAG application: added URL validation, improved error… #109
Conversation
… handling, and enhanced logging. Introduced custom exception handling and streamlined repository processing logic. Updated chat functionality for better user experience.
WalkthroughThis pull request refactors and extends the GitHub RAG application functionality. The changes add a custom exception class and new functions to validate GitHub URLs, extract repository names, process repository data, and create a query engine. Additionally, the repository loading logic has been restructured to include a progress spinner, improved logging, and enhanced session state management. The chat input handling has been updated to catch and log processing errors, ensuring that exceptions are managed more gracefully throughout the application. Changes

16-17: Logging configuration looks good.The logging setup with
INFOlevel andloggerinitialization is clear and standard.
25-28: Custom exception definition looks fine.The
GitHubRAGErrorclass clearly communicates application-specific errors.
102-109: Session state initialization looks correct.Storing a unique UUID and preparing caches is well-structured.
112-118: GitHub URL input and header are fine.The UI elements appear straightforward with a helpful placeholder and prompt.
120-120: Load repository button setup is clear.No issues found with this logic.
124-127: URL validation feedback.Positive approach to guard invalid URLs early. Looks good.
129-130: Repository name extraction is consistent.Handles creation of a unique key for caching with minimal overhead.
162-164: Exception handling for repository loading is appropriate.Catching unexpected errors and logging them is a good practice.
166-166: Section heading is well-noted.No issues identified here.
170-170: Header styling is acceptable.Clear indicator for the chat section.
172-173: Chat reset button usage is clean.Ties nicely to the
reset_chatfunction.
175-175: Comment for displaying chat history.Nothing problematic found.
181-226: Main chat logic is well-structured.The code gracefully handles user input, updates the session state, and uses the query engine. Adequate exception handling is present.

Raise original traceback for clarity.
When re-raising an exception in line 38, add from e to preserve the original traceback context.

Exception chaining recommended.
