Description

This fix addresses a static analysis violation where generic Exception was being caught before more specific exceptions in the ASGI middleware error handling.

The issue was in the exception handling order at line 460 of ddtrace/contrib/internal/asgi/middleware.py. The Exception handler was positioned before the BaseException handler, which violates the principle that generic exceptions must be caught last to allow specific exception handlers to execute properly.

The fix reorders the exception handlers so that BaseException is caught first, allowing it to handle both BlockingException (via find_exception) and regular Exception instances appropriately. This ensures specific exception types are properly handled before falling back to the generic exception handler.

Testing

The existing test suite for ASGI middleware should be run to verify that exception handling continues to work correctly for:

• BlockingException cases (both regular and within BaseExceptionGroup)
• Regular exceptions with proper span tagging
• All other exception types

Risks

Low risk. This change only reorders exception handlers without altering the underlying logic. The same operations are performed; they're simply organized in the correct order to follow Python best practices.

Additional Notes

This change maintains backward compatibility and ensures compliance with the python-best-practices/generic-exception-last static analysis rule across all affected branches.
