Richard van der Hoff	0e68e9b7f4	Fix bug in calculating state for non-gappy syncs (#16942) ... Unfortunately, the optimisation we applied here for non-gappy syncs is not actually valid. Fixes https://github.com/element-hq/synapse/issues/16941. ~~Based on https://github.com/element-hq/synapse/pull/16930.~~ Requires https://github.com/matrix-org/sytest/pull/1374.	2024-04-04 16:15:35 +00:00
Richard van der Hoff	05957ac70f	Fix bug in /sync response for archived rooms (#16932) ... This PR fixes a very, very niche edge-case, but I've got some more work coming which will otherwise make the problem worse. The bug happens when the syncing user leaves a room, and has a sync filter which includes "left" rooms, but sets the timeline limit to 0. In that case, the state returned in the `state` section is calculated incorrectly. The fix is to pass a token corresponding to the point that the user leaves the room through to `compute_state_delta`.	2024-04-04 12:47:59 +01:00
