From ffc2ee521d26f5b842df7902ade5de7a538e602d Mon Sep 17 00:00:00 2001 From: David Robertson Date: Thu, 16 Feb 2023 16:09:11 +0000 Subject: Use mypy 1.0 (#15052) * Update mypy and mypy-zope * Remove unused ignores These used to suppress ``` synapse/storage/engines/__init__.py:28: error: "__new__" must return a class instance (got "NoReturn") [misc] ``` and ``` synapse/http/matrixfederationclient.py:1270: error: "BaseException" has no attribute "reasons" [attr-defined] ``` (note that we check `hasattr(e, "reasons")` above) * Avoid empty body warnings, sometimes by marking methods as abstract E.g. ``` tests/handlers/test_register.py:58: error: Missing return statement [empty-body] tests/handlers/test_register.py:108: error: Missing return statement [empty-body] ``` * Suppress false positive about `JaegerConfig` Complaint was ``` synapse/logging/opentracing.py:450: error: Function "Type[Config]" could always be true in boolean context [truthy-function] ``` * Fix not calling `is_state()` Oops! ``` tests/rest/client/test_third_party_rules.py:428: error: Function "Callable[[], bool]" could always be true in boolean context [truthy-function] ``` * Suppress false positives from ParamSpecs ```` synapse/logging/opentracing.py:971: error: Argument 2 to "_custom_sync_async_decorator" has incompatible type "Callable[[Arg(Callable[P, R], 'func'), **P], _GeneratorContextManager[None]]"; expected "Callable[[Callable[P, R], **P], _GeneratorContextManager[None]]" [arg-type] synapse/logging/opentracing.py:1017: error: Argument 2 to "_custom_sync_async_decorator" has incompatible type "Callable[[Arg(Callable[P, R], 'func'), **P], _GeneratorContextManager[None]]"; expected "Callable[[Callable[P, R], **P], _GeneratorContextManager[None]]" [arg-type] ```` * Drive-by improvement to `wrapping_logic` annotation * Workaround false "unreachable" positives See https://github.com/Shoobx/mypy-zope/issues/91 ``` tests/http/test_proxyagent.py:626: error: Statement is unreachable [unreachable] tests/http/test_proxyagent.py:762: error: Statement is unreachable [unreachable] tests/http/test_proxyagent.py:826: error: Statement is unreachable [unreachable] tests/http/test_proxyagent.py:838: error: Statement is unreachable [unreachable] tests/http/test_proxyagent.py:845: error: Statement is unreachable [unreachable] tests/http/federation/test_matrix_federation_agent.py:151: error: Statement is unreachable [unreachable] tests/http/federation/test_matrix_federation_agent.py:452: error: Statement is unreachable [unreachable] tests/logging/test_remote_handler.py:60: error: Statement is unreachable [unreachable] tests/logging/test_remote_handler.py:93: error: Statement is unreachable [unreachable] tests/logging/test_remote_handler.py:127: error: Statement is unreachable [unreachable] tests/logging/test_remote_handler.py:152: error: Statement is unreachable [unreachable] ``` * Changelog * Tweak DBAPI2 Protocol to be accepted by mypy 1.0 Some extra context in: - https://github.com/matrix-org/python-canonicaljson/pull/57 - https://github.com/python/mypy/issues/6002 - https://mypy.readthedocs.io/en/latest/common_issues.html#covariant-subtyping-of-mutable-protocol-members-is-rejected * Pull in updated canonicaljson lib so the protocol check just works * Improve comments in opentracing I tried to workaround the ignores but found it too much trouble. I think the corresponding issue is https://github.com/python/mypy/issues/12909. The mypy repo has a PR claiming to fix this (https://github.com/python/mypy/pull/14677) which might mean this gets resolved soon? * Better annotation for INTERACTIVE_AUTH_CHECKERS * Drive-by AUTH_TYPE annotation, to remove an ignore --- synapse/rest/media/v1/_base.py | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) (limited to 'synapse/rest/media/v1/_base.py') diff --git a/synapse/rest/media/v1/_base.py b/synapse/rest/media/v1/_base.py index d30878f704..6e035afcce 100644 --- a/synapse/rest/media/v1/_base.py +++ b/synapse/rest/media/v1/_base.py @@ -16,6 +16,7 @@ import logging import os import urllib +from abc import ABC, abstractmethod from types import TracebackType from typing import Awaitable, Dict, Generator, List, Optional, Tuple, Type @@ -284,13 +285,14 @@ async def respond_with_responder( finish_request(request) -class Responder: +class Responder(ABC): """Represents a response that can be streamed to the requester.
