Added decorator `@get_user_params()` to various route handlers in `routes.py`. Adjusted user handling in `config.py` by eliminating checks for 'login' and directly accessing user parameters from Flask's global variable `g`. Also moved user retrieval process from `routes.py` to lower level operations allowing for better abstraction and less redundancy.
The code changes focus on enhancing the server application's functionality by improving the error handling mechanism and streamlining the logic. Modifications include refining how servers get created, updated, and deleted, optimizing how ssh related actions are performed, and ensuring more accurate server scanning. The changes help reduce potential errors and make the application more efficient.
