Pull Request Overview

This PR introduces a reusable utility for finding a specific Middleware type in a list and refactors existing code to use it, while updating component type hints.

• Adds findType in servc/util.py to locate a middleware instance by its class.
• Refactors HTTP blob component lookup in blob.py to use findType.
• Updates _components type annotations from List[type[Middleware]] to List[Middleware] in HTTP classes.

• Function names should follow PEP8 snake_case; consider renaming findType to find_type.

def findType(c: List[Middleware], type: type[T]) -> T:

servc/util.py:8

• Avoid shadowing the built-in type; rename this parameter to something like middleware_type for clarity.

def findType(c: List[Middleware], type: type[T]) -> T:

servc/util.py:11

• Improve the error message by using middleware_type.__name__ to display the class name, e.g., f"Middleware {middleware_type.__name__} not found".

raise ValueError(f"Middleware {type} not found")

servc/util.py:1

• The new findType utility lacks unit tests; add tests covering successful lookups and the error case.

from typing import List, TypeVar

servc/svc/com/http/blob.py:45

• BlobStorage is not imported in this module, which will cause a NameError. Please add the correct import for BlobStorage.

self._blobStorage = findType(components, BlobStorage)
