From 7982891794e26cabe18448f4e0ec0d301f13d186 Mon Sep 17 00:00:00 2001 From: Sean Quah <8349537+squahtx@users.noreply.github.com> Date: Mon, 12 Dec 2022 18:13:43 +0000 Subject: [PATCH] Fix missing cache invalidation in application service code (#14670) #11915 introduced the `@cached` `is_interested_in_room` method in Synapse 1.55.0, which depends upon `get_aliases_for_room`. Add a missing cache invalidation callback so that the `is_interested_in_room` cache is invalidated when `get_aliases_for_room` is invalidated. #13787 made `get_rooms_for_user` `@cached`. Add a missing cache invalidation callback so that the `is_interested_in_presence` cache is invalidated when `get_rooms_for_user` is invalidated.
