Erik Johnston	588e5b521d	Sliding Sync: Retrieve fewer events from DB in sync (#17688) ... When using timeline limit of 1 we end up fetching 2 events from the DB purely to tell if the response was "limited" or not. Lets not do that.	2024-09-10 09:52:42 +01:00
Eric Eastwood	5389374ef8	Sliding Sync: Speed up incremental sync by avoiding extra work (#17665) ... Speed up incremental sync by avoiding extra work. We first look at the state delta changes and only fetch and calculate further derived things if they have changed.	2024-09-09 10:36:22 +01:00

Quentin Gliech	ca69d0f571	MSC3861: load the issuer and account management URLs from OIDC discovery (#17407) ... This will help mitigating any discrepancies between the issuer configured and the one returned by the OIDC provider. This also removes the need for configuring the `account_management_url` explicitely, as it will now be loaded from the OIDC discovery, as per MSC2965. Because we may now fetch stuff for the .well-known/matrix/client endpoint, this also transforms the client well-known resource to be asynchronous.	2024-08-30 14:04:08 +00:00

Eric Eastwood	1a6b718f8c	Sliding Sync: Pre-populate room data for quick filtering/sorting (#17512) ... Pre-populate room data for quick filtering/sorting in the Sliding Sync API Spawning from https://github.com/element-hq/synapse/pull/17450#discussion_r1697335578 This PR is acting as the Synapse version `N+1` step in the gradual migration being tracked by https://github.com/element-hq/synapse/issues/17623 Adding two new database tables: - `sliding_sync_joined_rooms`: A table for storing room meta data that the local server is still participating in. The info here can be shared across all `Membership.JOIN`. Keyed on `(room_id)` and updated when the relevant room current state changes or a new event is sent in the room. - `sliding_sync_membership_snapshots`: A table for storing a snapshot of room meta data at the time of the local user's membership. Keyed on `(room_id, user_id)` and only updated when a user's membership in a room changes. Also adds background updates to populate these tables with all of the existing data. We want to have the guarantee that if a row exists in the sliding sync tables, we are able to rely on it (accurate data). And if a row doesn't exist, we use a fallback to get the same info until the background updates fill in the rows or a new event comes in triggering it to be fully inserted. This means we need a couple extra things in place until we bump `SCHEMA_COMPAT_VERSION` and run the foreground update in the `N+2` part of the gradual migration. For context on why we can't rely on the tables without these things see [1]. 1. On start-up, block until we clear out any rows for the rooms that have had events since the max-`stream_ordering` of the `sliding_sync_joined_rooms` table (compare to max-`stream_ordering` of the `events` table). For `sliding_sync_membership_snapshots`, we can compare to the max-`stream_ordering` of `local_current_membership` - This accounts for when someone downgrades their Synapse version and then upgrades it again. This will ensure that we don't have any stale/out-of-date data in the `sliding_sync_joined_rooms`/`sliding_sync_membership_snapshots` tables since any new events sent in rooms would have also needed to be written to the sliding sync tables. For example a new event needs to bump `event_stream_ordering` in `sliding_sync_joined_rooms` table or some state in the room changing (like the room name). Or another example of someone's membership changing in a room affecting `sliding_sync_membership_snapshots`. 1. Add another background update that will catch-up with any rows that were just deleted from the sliding sync tables (based on the activity in the `events`/`local_current_membership`). The rooms that need recalculating are added to the `sliding_sync_joined_rooms_to_recalculate` table. 1. Making sure rows are fully inserted. Instead of partially inserting, we need to check if the row already exists and fully insert all data if not. All of this extra functionality can be removed once the `SCHEMA_COMPAT_VERSION` is bumped with support for the new sliding sync tables so people can no longer downgrade (the `N+2` part of the gradual migration). <details> <summary><sup>[1]</sup></summary> For `sliding_sync_joined_rooms`, since we partially insert rows as state comes in, we can't rely on the existence of the row for a given `room_id`. We can't even rely on looking at whether the background update has finished. There could still be partial rows from when someone reverted their Synapse version after the background update finished, had some state changes (or new rooms), then upgraded again and more state changes happen leaving a partial row. For `sliding_sync_membership_snapshots`, we insert items as a whole except for the `forgotten` column ~~so we can rely on rows existing and just need to always use a fallback for the `forgotten` data. We can't use the `forgotten` column in the table for the same reasons above about `sliding_sync_joined_rooms`.~~ We could have an out-of-date membership from when someone reverted their Synapse version. (same problems as outlined for `sliding_sync_joined_rooms` above) Discussed in an [internal meeting](https://docs.google.com/document/d/1MnuvPkaCkT_wviSQZ6YKBjiWciCBFMd-7hxyCO-OCbQ/edit#bookmark=id.dz5x6ef4mxz7) </details> ### TODO - [x] Update `stream_ordering`/`bump_stamp` - [x] Handle remote invites - [x] Handle state resets - [x] Consider adding `sender` so we can filter `LEAVE` memberships and distinguish from kicks. - [x] We should add it to be able to tell leaves from kicks - [x] Consider adding `tombstone` state to help address https://github.com/element-hq/synapse/issues/17540 - [x] We should add it `tombstone_successor_room_id` - [x] Consider adding `forgotten` status to avoid extra lookup/table-join on `room_memberships` - [x] We should add it - [x] Background update to fill in values for all joined rooms and non-join membership - [x] Clean-up tables when room is deleted - [ ] Make sure tables are useful to our use case - First explored in https://github.com/element-hq/synapse/compare/erikj/ss_use_new_tables - Also explored in 76b5a576eb - [x] Plan for how can we use this with a fallback - See plan discussed above in main area of the issue description - Discussed in an [internal meeting](https://docs.google.com/document/d/1MnuvPkaCkT_wviSQZ6YKBjiWciCBFMd-7hxyCO-OCbQ/edit#bookmark=id.dz5x6ef4mxz7) - [x] Plan for how we can rely on this new table without a fallback - Synapse version `N+1`: (this PR) Bump `SCHEMA_VERSION` to `87`. Add new tables and background update to backfill all rows. Since this is a new table, we don't have to add any `NOT VALID` constraints and validate them when the background update completes. Read from new tables with a fallback in cases where the rows aren't filled in yet. - Synapse version `N+2`: Bump `SCHEMA_VERSION` to `88` and bump `SCHEMA_COMPAT_VERSION` to `87` because we don't want people to downgrade and miss writes while they are on an older version. Add a foreground update to finish off the backfill so we can read from new tables without the fallback. Application code can now rely on the new tables being populated. - Discussed in an [internal meeting](https://docs.google.com/document/d/1MnuvPkaCkT_wviSQZ6YKBjiWciCBFMd-7hxyCO-OCbQ/edit#bookmark=id.hh7shg4cxdhj) ### Dev notes ``` SYNAPSE_TEST_LOG_LEVEL=INFO poetry run trial tests.storage.test_events.SlidingSyncPrePopulatedTablesTestCase SYNAPSE_POSTGRES=1 SYNAPSE_POSTGRES_USER=postgres SYNAPSE_TEST_LOG_LEVEL=INFO poetry run trial tests.storage.test_events.SlidingSyncPrePopulatedTablesTestCase ``` ``` SYNAPSE_TEST_LOG_LEVEL=INFO poetry run trial tests.handlers.test_sliding_sync.FilterRoomsTestCase ``` Reference: - [Development docs on background updates and worked examples of gradual migrations ](1dfa59b238/docs/development/database_schema.md (background-updates)) - A real example of a gradual migration: https://github.com/matrix-org/synapse/pull/15649#discussion_r1213779514 - Adding `rooms.creator` field that needed a background update to backfill data, https://github.com/matrix-org/synapse/pull/10697 - Adding `rooms.room_version` that needed a background update to backfill data, https://github.com/matrix-org/synapse/pull/6729 - Adding `room_stats_state.room_type` that needed a background update to backfill data, https://github.com/matrix-org/synapse/pull/13031 - Tables from MSC2716: `insertion_events`, `insertion_event_edges`, `insertion_event_extremities`, `batch_events` - `current_state_events` updated in `synapse/storage/databases/main/events.py` --- ``` persist_event (adds to queue) _persist_event_batch _persist_events_and_state_updates (assigns `stream_ordering` to events) _persist_events_txn _store_event_txn _update_metadata_tables_txn _store_room_members_txn _update_current_state_txn ``` --- > Concatenated Indexes [...] (also known as multi-column, composite or combined index) > > [...] key consists of multiple columns. > > We can take advantage of the fact that the first index column is always usable for searching > > *-- https://use-the-index-luke.com/sql/where-clause/the-equals-operator/concatenated-keys* --- Dealing with `portdb` (`synapse/_scripts/synapse_port_db.py`), https://github.com/element-hq/synapse/pull/17512#discussion_r1725998219 --- <details> <summary>SQL queries:</summary> Both of these are equivalent and work in SQLite and Postgres Options 1: ```sql WITH data_table (room_id, user_id, membership_event_id, membership, event_stream_ordering, {", ".join(insert_keys)}) AS ( VALUES ( ?, ?, ?, (SELECT membership FROM room_memberships WHERE event_id = ?), (SELECT stream_ordering FROM events WHERE event_id = ?), {", ".join("?" for _ in insert_values)} ) ) INSERT INTO sliding_sync_non_join_memberships (room_id, user_id, membership_event_id, membership, event_stream_ordering, {", ".join(insert_keys)}) SELECT * FROM data_table WHERE membership != ?

Eric Eastwood	a308d99f30	Sliding Sync: Exclude partially stated rooms if we must await full state (#17538) ... Previously, we just had very basic partial room exclusion based on whether we were lazy-loading room members. Now with this PR, we added `must_await_full_state(...)` with rules to check if we have a we're only requesting `required_state` which is completely satisfied even with partial state. Partially-stated rooms should have all state events except for remote membership events so if we require a remote membership event anywhere, then we need to return `True`.	2024-08-13 12:27:42 -05:00

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

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. When no joined or invited members are available, this should consist of the banned and left users. > > *-- https://spec.matrix.org/v1.10/client-server-api/#_matrixclientv3sync_roomsummary* Related to https://github.com/matrix-org/matrix-spec/issues/1334	2024-07-17 13:10:15 -05:00
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

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
Shay	cf69f8d59b	Support MSC3916 by adding a federation /thumbnail endpoint and authenticated _matrix/client/v1/media/thumbnail endpoint (#17388) ... [MSC3916](https://github.com/matrix-org/matrix-spec-proposals/pull/3916) added the endpoints `_matrix/federation/v1/media/thumbnail` and the authenticated `_matrix/client/v1/media/thumbnail`.

Erik Johnston	b3b793786c	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 12:39:49 +01:00
