From cf66d712c615b96bce19e44118cce1ebda41d0b8 Mon Sep 17 00:00:00 2001 From: Sean Quah <8349537+squahtx@users.noreply.github.com> Date: Thu, 26 Jan 2023 10:38:49 +0000 Subject: [PATCH] Fix initialization of `_device_list_id_gen` (#14914) On startup, the `_device_list_id_gen` stream id generator is initialized using the maximum stream id seen in a list of tables. When we started populating the `device_list_remote_pending` table in #13913, we forgot to add it to the aforementioned list of tables, so the stream id generator can hand out old stream ids after a restart. The end result is that Synapse can fail to handle device list update EDUs after a restart when a partial state join is in progress. Add the `device_list_remote_pending` table to the list of tables to consider when initializing the `_device_list_id_gen` stream id generator.
