From 197fae16398a3cacc310fbba6e1dc343f552fd03 Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Tue, 26 Mar 2019 12:45:22 +0000 Subject: Use event streams to calculate presence Primarily this fixes a bug in the handling of remote users joining a room where the server sent out the presence for all local users in the room to all servers in the room. We also change to using the state delta stream, rather than the distributor, as it will make it easier to split processing out of the master process (as well as being more flexible). Finally, when sending presence states to newly joined servers we filter out old presence states to reduce the number sent. Initially we filter out states that are offline and have a last active more than a week ago, though this can be changed down the line.
