Erik Johnston	44ac2aa3b6	SSS: Implement PREVIOUSLY room tracking (#17535) ... Implement tracking of rooms that have had updates that have not been sent down to clients. Simplified Sliding Sync (SSS)	2024-08-08 10:44:17 +01:00
Eric Eastwood	11db575218	Sliding Sync: Use stream_ordering based timeline pagination for incremental sync (#17510) ... Use `stream_ordering` based `timeline` pagination for incremental `/sync` in Sliding Sync. Previously, we were always using a `topological_ordering` but we should only be using that for historical scenarios (initial `/sync`, newly joined, or haven't sent the room down the connection before). This is slightly different than what the [spec suggests](https://spec.matrix.org/v1.10/client-server-api/#syncing) > Events are ordered in this API according to the arrival time of the event on the homeserver. This can conflict with other APIs which order events based on their partial ordering in the event graph. This can result in duplicate events being received (once per distinct API called). Clients SHOULD de-duplicate events based on the event ID when this happens. But we've had a [discussion below in this PR](https://github.com/element-hq/synapse/pull/17510#discussion_r1699105569) and this matches what Sync v2 already does and seems like it makes sense. Created a spec issue https://github.com/matrix-org/matrix-spec/issues/1917 to clarify this.

Erik Johnston	c270355349	SS: Reset connection if token is unrecognized (#17529) ... This triggers the client to start a new sliding sync connection. If we don't do this and the client asks for the full range of rooms, we end up sending down all rooms and their state from scratch (which can be very slow) This causes things like https://github.com/element-hq/element-x-ios/issues/3115 after we restart the server --------- Co-authored-by: Eric Eastwood <eric.eastwood@beta.gouv.fr>	2024-08-06 10:39:11 +01:00

Part of [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575): Sliding Sync Follow-up to https://github.com/element-hq/synapse/pull/17434 We now take into account current state, fallback to stripped state for invite/knock rooms, then historical state.

Erik Johnston	be4a16ff44	Sliding Sync: Track whether we have sent rooms down to clients (#17447) ... The basic idea is that we introduce a new token for a sliding sync connection, which stores the mapping of room to room "status" (i.e. have we sent the room down?). This token allows us to handle duplicate requests properly. In future it can be used to store more "per-connection" information safely. In future this should be migrated into the DB, so its important that we try to reduce the number of syncs where we need to update the per-connection information. In this PoC this only happens when we: a) send down a set of room for the first time, or b) we have previously sent down a room and there are updates but we are not sending the room down the sync (due to not falling in a list range) Co-authored-by: Eric Eastwood <eric.eastwood@beta.gouv.fr>	2024-07-29 22:45:48 +01:00

Erik Johnston	bdf37ad4c4	Sliding Sync: ensure bump stamp ignores backfilled events (#17478) ... Backfill events have a negative stream ordering, and so its not useful to use to compare with other (positive) stream orderings.

We basically invalidate it in all the same places as `get_rooms_for_user`.

Eric Eastwood	3fee32ed6b	Order heroes by stream_ordering (as spec'ed) (#17435) ... The spec specifically mentions `stream_ordering` but that's a Synapse specific concept. In any case, the essence of the spec is basically the first 5 members of the room which `stream_ordering` accomplishes. Split off from https://github.com/element-hq/synapse/pull/17419#discussion_r1671342794 ## Spec compliance > This should be the first 5 members of the room, **ordered by stream ordering**, which are joined or invited. The list must never include the client’s own user ID.

Shay	429ecb7564	Handle remote download responses with UNKNOWN_LENGTH more gracefully (#17439) ... Prior to this PR, remote downloads which did not provide a `content-length` were decremented from the remote download ratelimiter at the max allowable size, leading to excessive ratelimiting - see https://github.com/element-hq/synapse/issues/17394. This PR adds a linearizer to limit concurrent remote downloads to 6 per IP address, and decrements remote downloads without a `content-length` from the ratelimiter *after* the download is complete and the response length is known. Also adds logic to ensure that responses with a known length respect the `max_download_size`.	2024-07-16 11:13:55 +01:00

Erik Johnston	8cdd2d214e	Fix bug in sliding sync when using old DB. (#17398) ... We don't necessarily have `instance_name` for old events (before we support multiple event persisters).

Eric Eastwood	3fef535ff2	Add rooms.bump_stamp to Sliding Sync /sync for easier client-side sorting (#17395) ... `bump_stamp` corresponds to the `stream_ordering` of the latest `DEFAULT_BUMP_EVENT_TYPES` in the room. This helps clients sort more readily without them needing to pull in a bunch of the timeline to determine the last activity. `bump_event_types` is a thing because for example, we don't want display name changes to mark the room as unread and bump it to the top. For encrypted rooms, we just have to consider any activity as a bump because we can't see the content and the client has to figure it out for themselves. Outside of Synapse, `bump_stamp` is just a free-form counter so other implementations could use `received_ts`or `origin_server_ts` (see the [*Security considerations* section in MSC3575 about the potential pitfalls of using `origin_server_ts`](https://github.com/matrix-org/matrix-spec-proposals/blob/kegan/sync-v3/proposals/3575-sync.md#security-considerations)). It doesn't have any guarantee about always going up. In the Synapse case, it could go down if an event was redacted/removed (or purged in cases of retention policies). In the future, we could add `bump_event_types` as [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575) mentions if people need to customize the event types. --- In the Sliding Sync proxy, a similar [`timestamp` field was added](https://github.com/matrix-org/sliding-sync/pull/247) for the same purpose but the name is not obvious what it pertains to or what it's for. The `timestamp` field was also added to Ruma in https://github.com/ruma/ruma/pull/1622	2024-07-08 13:17:08 -05:00

Erik Johnston	1ce59d7ba0	Fix sync waiting for an invalid token from the "future" (#17386) ... Fixes https://github.com/element-hq/synapse/issues/17274, hopefully. Basically, old versions of Synapse could advance streams without persisting anything in the DB (fixed in #17229). On restart those updates would get lost, and so the position of the stream would revert to an older position. If this happened across an upgrade to a later Synapse version which included #17215, then sync could get blocked indefinitely (until the stream advanced to the position in the token). We fix this by bounding the stream positions we'll wait for to the maximum position of the underlying stream ID generator.	2024-07-02 12:40:03 +01:00
