* Convert Sliding Sync tests to use higher-level `compute_interested_rooms` ↵Devon Hudson2025-05-071-396/+986
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#18399) Spawning from https://github.com/element-hq/synapse/pull/18375#discussion_r2071768635, This updates some sliding sync tests to use a higher level function in order to move test coverage to cover both fallback & new tables. Important when https://github.com/element-hq/synapse/pull/18375 is merged. In other words, adjust tests to target `compute_interested_room(...)` (relevant to both new and fallback path) instead of the lower level `get_room_membership_for_user_at_to_token(...)` that only applies to the fallback path. ### Dev notes ``` SYNAPSE_TEST_LOG_LEVEL=INFO poetry run trial tests.handlers.test_sliding_sync.ComputeInterestedRoomsTestCase_new ``` ``` SYNAPSE_TEST_LOG_LEVEL=INFO poetry run trial tests.rest.client.sliding_sync ``` ``` SYNAPSE_POSTGRES=1 SYNAPSE_POSTGRES_USER=postgres SYNAPSE_TEST_LOG_LEVEL=INFO poetry run trial tests.handlers.test_sliding_sync.ComputeInterestedRoomsTestCase_new.test_display_name_changes_leave_after_token_range ``` ### Pull Request Checklist <!-- Please read https://element-hq.github.io/synapse/latest/development/contributing_guide.html before submitting your pull request --> * [x] Pull request is based on the develop branch * [x] Pull request includes a [changelog file](https://element-hq.github.io/synapse/latest/development/contributing_guide.html#changelog).

* Correctly changes to required state config in sliding sync (#17785)Erik Johnston2024-10-141-2/+692
| | | | | | | | | | | | | | | | | | Fixes https://github.com/element-hq/synapse/issues/17698 This handles `required_state` changes by checking if new state has been added to the config, and if so fetching and returning that from the current state. This also takes care to ensure that given a state entry S that is added, removed and then re-added that we do *not* send S down a second time if there have been no changes to S in the current state. This is fine for Rust SDK (as it just remembers all state), but we might decide not to do this behaviour in the MSC. If we decide to always send down S then its easy enough to rip out all the code. --------- Co-authored-by: Eric Eastwood <eric.eastwood@beta.gouv.fr>
* Sliding Sync: Move filters tests to rest layer (#17703)Eric Eastwood2024-09-121-1384/+1
| | | | | | | | | | | | | Move filters tests to rest layer in order to test the new (with sliding sync tables) and fallback paths that Sliding Sync can use. Also found a bug in the new path because it's not being tested which is also fixed in this PR. We now take into account `has_known_state` when filtering. Spawning from https://github.com/element-hq/synapse/pull/17662#discussion_r1755574791. This should have been done when we started using the new sliding sync tables in https://github.com/element-hq/synapse/pull/17630
* Speed up sliding sync by avoiding copies (#17670)Erik Johnston2024-09-061-151/+195
| | | | | | | | | We ended up spending ~10% CPU creating a new dictionary and `_RoomMembershipForUser`, so let's avoid creating new dicts and copying by returning `newly_joined`, `newly_left` and `is_dm` as sets directly. --------- Co-authored-by: Eric Eastwood <eric.eastwood@beta.gouv.fr>
* Sliding Sync: Make `PerConnectionState` immutable (#17600)Erik Johnston2024-08-291-18/+5
| | | | | | | | | | | | | | | | | This is so that we can cache it. We also move the sliding sync types to `synapse/types/handlers/sliding_sync.py`. This is mainly in-prep for #17599 to avoid circular imports. The only change in behaviour is that `RoomSyncConfig.combine_sync_config(..)` now returns a new room sync config rather than mutating in-place. Reviewable commit-by-commit. --------- Co-authored-by: Eric Eastwood <eric.eastwood@beta.gouv.fr>
* Sliding sync: factor out room list logic (#17622)Erik Johnston2024-08-281-76/+76
| | | | | | | | | Move calculating of the room lists out of the core handler. This should make it easier to switch things around to start using the tables in #17512. This is just moving code between files and methods. Reviewable commit-by-commit
* Sliding Sync: Update filters to be robust against remote invite rooms (#17450)Eric Eastwood2024-07-301-34/+840
| | | | | | | | | | | | | | | Update `filters.is_encrypted` and `filters.types`/`filters.not_types` to be robust when dealing with remote invite rooms in Sliding Sync. 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. If we can't determine the info needed to filter a room (either from state or stripped state), it is filtered out.
* Add room subscriptions to Sliding Sync `/sync` (#17432)Eric Eastwood2024-07-151-180/+865
| | | | | | | | | | | | | Add room subscriptions to Sliding Sync `/sync` Based on [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575): Sliding Sync Currently, you can only subscribe to rooms you have had *any* membership in before. In the future, we will allow `world_readable` rooms to be subscribed to without joining.
* Fix filtering room types on remote rooms (#17434)Erik Johnston2024-07-111-0/+68
| | | | | | We can only fetch room types for rooms the server is in, so we need to only filter rooms that we're joined to. Also includes a perf fix to bulk fetch room types.
* Add `rooms.bump_stamp` to Sliding Sync `/sync` for easier client-side ↵Eric Eastwood2024-07-081-4/+64
| | | | | | | | | | | | | | | 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
* Add `rooms.required_state` to Sliding Sync `/sync` (#17342)Eric Eastwood2024-07-041-2/+534

* Fix `newly_left` rooms not appearing if we returned early (Sliding Sync) ↵Eric Eastwood2024-06-131-1/+1
| | | | | | | | | | | (#17301) Fix `newly_left` rooms not appearing if we returned early when `membership_snapshot_token.is_before_or_eq(to_token.room_key)`. Introduced in https://github.com/element-hq/synapse/pull/17187 (part of Sliding Sync) The tests didn't catch it because they had a small typo in it `room_id1` vs `room_id2`. Found while working on https://github.com/element-hq/synapse/pull/17293
* Add Sliding Sync `/sync` endpoint (initial implementation) (#17187)Eric Eastwood2024-06-061-0/+1118
Based on [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575): Sliding Sync This iteration only focuses on returning the list of room IDs in the sliding window API (without sorting/filtering). Rooms appear in the Sliding sync response based on: - `invite`, `join`, `knock`, `ban` membership events - Kicks (`leave` membership events where `sender` is different from the `user_id`/`state_key`) - `newly_left` (rooms that were left during the given token range, > `from_token` and <= `to_token`) - In order for bans/kicks to not show up, you need to `/forget` those rooms. This doesn't modify the event itself though and only adds the `forgotten` flag to `room_memberships` in Synapse. There isn't a way to tell when a room was forgotten at the moment so we can't factor it into the from/to range. ### Example request `POST http://localhost:8008/_matrix/client/unstable/org.matrix.msc3575/sync` ```json { "lists": { "foo-list": { "ranges": [ [0, 99] ], "sort": [ "by_notification_level", "by_recency", "by_name" ], "required_state": [ ["m.room.join_rules", ""], ["m.room.history_visibility", ""], ["m.space.child", "*"] ], "timeline_limit": 100 } } } ``` Response: ```json { "next_pos": "s58_224_0_13_10_1_1_16_0_1", "lists": { "foo-list": { "count": 1, "ops": [ { "op": "SYNC", "range": [0, 99], "room_ids": [ "!MmgikIyFzsuvtnbvVG:my.synapse.linux.server" ] } ] } }, "rooms": {}, "extensions": {} } ```
