From 5a7dd058184613c70041a61fdbc2ccce104bb500 Mon Sep 17 00:00:00 2001 From: Kegan Dougal Date: Mon, 9 Feb 2015 14:14:15 +0000 Subject: [PATCH] Modify auth.get_user_by_req for authing appservices directly. Add logic to map the appservice token to the autogenned appservice user ID. Add unit tests for all forms of get_user_by_req (user/appservice, valid/bad/missing tokens) --- synapse/api/auth.py | 34 +++--- synapse/storage/appservice.py | 4 +- tests/api/test_auth.py | 139
