From 6d47b7e32589e816eb766446cc1ff19ea73fc7c1 Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Tue, 22 Nov 2022 14:08:04 -0500 Subject: Add a type hint for `get_device_handler()` and fix incorrect types. (#14055) This was the last untyped handler from the HomeServer object. Since it was being treated as Any (and thus unchecked) it was being used incorrectly in a few places. --- synapse/handlers/deactivate_account.py | 4 +++ synapse/handlers/device.py | 65 ++++++++++++++++++++++++++-------- synapse/handlers/e2e_keys.py | 61 ++++++++++++++++--------------- synapse/handlers/register.py | 4 +++ synapse/handlers/set_password.py | 6 +++- synapse/handlers/sso.py | 9 +++++ synapse/module_api/__init__.py | 10 +++++- synapse/replication/http/devices.py | 11 ++++-- synapse/rest/admin/__init__.py | 26 ++++++++------ synapse/rest/admin/devices.py | 13 +++++-- synapse/rest/client/devices.py | 17 ++++++--- synapse/rest/client/logout.py | 9 +++-- synapse/server.py | 2 +- 13 files changed, 167 insertions(+), 70 deletions(-) (limited to 'synapse') diff --git a/synapse/handlers/deactivate_account.py b/synapse/handlers/deactivate_account.py index 816e1a6d79..d74d135c0c 100644 --- a/synapse/handlers/deactivate_account.py +++ b/synapse/handlers/deactivate_account.py @@ -16,6 +16,7 @@ import logging from typing import TYPE_CHECKING, Optional from synapse.api.errors import SynapseError +from synapse.handlers.device import DeviceHandler from synapse.metrics.background_process_metrics import run_as_background_process from synapse.types import Codes, Requester, UserID, create_requester @@ -76,6 +77,9 @@ class DeactivateAccountHandler: True if identity server supports removing threepids, otherwise False.
