Disallow untyped defs in synapse._scripts (#12422) Of note: * No untyped defs in `register_new_matrix_user` This one might be contraversial. `request_registration` has three dependency-injection arguments used for testing. I'm removing the injection of the `requests` module and using `unitest.mock.patch` in the test cases instead. Doing `reveal_type(requests)` and `reveal_type(requests.get)` before the change: ``` synapse/_scripts/register_new_matrix_user.py:45: note: Revealed type is "Any" synapse/_scripts/register_new_matrix_user.py:46: note: Revealed type is "Any" ``` And after: ``` synapse/_scripts/register_new_matrix_user.py:44: note: Revealed type is "types.ModuleType" synapse/_scripts/register_new_matrix_user.py:45: note: Revealed type is "def (url: Union[builtins.str, builtins.bytes], params: Union[Union[_typeshed.SupportsItems[Union[builtins.str, builtins.bytes, builtins.int, builtins.float], Union[builtins.str, builtins.bytes, builtins.int, builtins.float, typing.Iterable[Union[builtins.str, builtins.bytes, builtins.int, builtins.float]], None]], Tuple[Union[builtins.str, builtins.bytes, builtins.int, builtins.float], Union[builtins.str, builtins.bytes, builtins.int, builtins.float, typing.Iterable[Union[builtins.str, builtins.bytes, builtins.int, builtins.float]], None]], typing.Iterable[Tuple[Union[builtins.str, builtins.bytes, builtins.int, builtins.float], Union[builtins.str, builtins.bytes, builtins.int, builtins.float, typing.Iterable[Union[builtins.str, builtins.bytes, builtins.int, builtins.float]], None]]], builtins.str, builtins.bytes], None] =, data: Union[Any, None] =, headers: Union[Any, None] =, cookies: Union[Any, None] =, files: Union[Any, None] =, auth: Union[Any, None] =, timeout: Union[Any, None] =, allow_redirects: builtins.bool =, proxies: Union[Any, None] =, hooks: Union[Any, None] =, stream: Union[Any, None] =, verify: Union[Any, None] =, cert: Union[Any, None] =, json: Union[Any, None] =) -> requests.models.Response" ``` * Drive-by comment in `synapse.storage.types` * No untyped defs in `synapse_port_db` This was by far the most painful. I'm happy to break this up into smaller pieces for review if it's not managable as-is.
