* Support MSC3916 by adding a federation /thumbnail endpoint and authenticated ↵Shay2024-07-088-47/+178
| | | | | | | | | | | | | | `_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`. This PR implements those endpoints, along with stabilizing `_matrix/client/v1/media/config` and `_matrix/client/v1/media/preview_url`. Complement tests are at https://github.com/matrix-org/complement/pull/728

| | | Based on #17392
* Finish up work to allow per-user feature flags (#17392)Erik Johnston2024-07-054-26/+98
| | | | | | | Follows on from @H-Shay's great work at https://github.com/matrix-org/synapse/pull/15344 and MSC4026. Also enables its use for MSC3881, mainly as an easy but concrete example of how to use it.
* Upon deactivation, forget all of the user's rooms (#17400)Travis Ralston2024-07-051-0/+4
| | | | | | This can help ensure that the rooms are eventually purged if the other local users also forget them. Synapse already clears some of the room information as part of the `_background_remove_left_rooms` background task, but this doesn't catch `events`, `event_json`, etc.
* Add `rooms.required_state` to Sliding Sync `/sync` (#17342)Eric Eastwood2024-07-045-81/+433
| | | Also handles excluding rooms with partial state when people are asking for room membership events unless it's `$LAZY` room membership.

| * Fix regression when bounding future tokens (#17391)Erik Johnston2024-07-021-4/+22
| | | | | | | | | | | | Fix bug added in #17386, where we accidentally used `room_key` for the receipts stream. See first commit. Reviewable commit-by-commit
| * Fix sync waiting for an invalid token from the "future" (#17386)Erik Johnston2024-07-0214-29/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Handle multiple rows device inbox (#17362)Erik Johnston2024-06-271-3/+2
|/ | | | | | | | | | Fix bug where we don't get new to-device from remote if they resent a message we've already persisted and have recorded in the DB twice. `device_federation_inbox` table doesn't have a unique index, and so we can race and store an entry in there twice. If we do so then `simple_select_one_txn` will throw an error due to the query returning more than one row. We should add an unique index, but it doesn't really matter so lets just handle the case of multiple rows correctly for now.

* Limit amount of replication we send (#17358)Erik Johnston2024-06-251-8/+7
| | | | | | | | | Fixes up #17333, where we failed to actually send less data (the `DISTINCT` didn't work due to `stream_id` being different). We fix this by making it so that every device list outbound poke for a given user ID has the same stream ID. We can't change the query to only return e.g. max stream ID as the receivers look up the destinations to send to by doing `SELECT WHERE stream_id = ?`

| | | | | | | This is #17291 (which got reverted), with some added fixups, and change so that tests actually pick up the error. The problem was that we were not calculating any new chain IDs due to a missing `not` in a condition.

* Reduce device lists replication traffic. (#17333)Erik Johnston2024-06-244-48/+80
| | | | | | | | | | Reduce the replication traffic of device lists, by not sending every destination that needs to be sent the device list update over replication. Instead a "hosts to send to have been calculated" notification over replication, and then federation senders read the destinations from the DB. For non federation senders this should heavily reduce the impact of a user in many large rooms changing a device.
* Tidy up integer parsing (#17339)Denis Kasak2024-06-247-34/+24
| | | | | | | | | | The parse_integer function was previously made to reject negative values by default in https://github.com/element-hq/synapse/pull/16920, but the documentation stated otherwise. This fixes the documentation and also: - Removes explicit negative=False parameters from call sites. - Brings the negative default of parse_integer_from_args in alignment with parse_integer.

| | | | | | | | | | | | | | | | | | | | | | (#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 `event.internal_metadata.instance_name` (#17300)Eric Eastwood2024-06-135-6/+16
| | | | | | | | | | | | | | | | | | | | Add `event.internal_metadata.instance_name` (the worker instance that persisted the event) to go alongside the existing `event.internal_metadata.stream_ordering`. `instance_name` is useful to properly compare and query for events with a token since you need to compare both the `stream_ordering` and `instance_name` against the vector clock/`instance_map` in the `RoomStreamToken`. This is pre-requisite work and may be used in https://github.com/element-hq/synapse/pull/17293 Adding `event.internal_metadata.instance_name` was first mentioned in the initial Sliding Sync PR while pairing with @erikjohnston, see https://github.com/element-hq/synapse/pull/17187/commits/09609cb0dbca3a4cfd9fbf90cc962e765ec469c0#diff-5cd773fb307aa754bd3948871ba118b1ef0303f4d72d42a2d21e38242bf4e096R405-R410

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": {} } ```

* Fix deduplicating of membership events to not create unused state groups. ↵Erik Johnston2024-05-302-35/+32
| | | | | | | | | | | | | (#17164) We try and deduplicate in two places: 1) really early on, and 2) just before we persist the event. The first case was broken due to it occuring before the profile information was added, and so it thought the event contents were different. The second case did catch it and handle it correctly, however doing so creates a redundant state group leading to bloat. Fixes #3791

* Move towards using `MultiWriterIdGenerator` everywhere (#17226)Erik Johnston2024-05-298-215/+153
| | | | | | | | | | | | | | | There is a problem with `StreamIdGenerator` where it can go backwards over restarts when a stream ID is requested but then not inserted into the DB. This is problematic if we want to land #17215, and is generally a potential cause for all sorts of nastiness. Instead of trying to fix `StreamIdGenerator`, we may as well move to `MultiWriterIdGenerator` that does not suffer from this problem (the latest positions are stored in `stream_positions` table). This involves adding SQLite support to the class. This only changes id generators that were already using `MultiWriterIdGenerator` under postgres, a separate PR will move the rest of the uses of `StreamIdGenerator` over.

| | | | | | | | Currently sending a to-device message to a user ID with a dodgy destination is accepted, but then ends up spamming the logs when we try and send to the destination. An alternative would be to reject the request, but I'm slightly nervous that could break things.

* Fix slipped logging context when media rejected (#17239)Erik Johnston2024-05-293-77/+40
| | | | | | | When a module rejects a piece of media we end up trying to close the same logging context twice. Instead of fixing the existing code we refactor to use an async context manager, which is easier to write correctly.
* Support MSC3916 by adding unstable media endpoints to `_matrix/client` (#17213)Shay2024-05-244-468/+703
| | | | | | | | | | [MSC3916](https://github.com/matrix-org/matrix-spec-proposals/blob/rav/authentication-for-media/proposals/3916-authentication-for-media.md) adds new media endpoints under `_matrix/client`. This PR adds the `/preview_url`, `/config`, and `/thumbnail` endpoints. `/download` will be added in a follow-up PR once the work for the federation `/download` endpoint is complete (see https://github.com/element-hq/synapse/pull/17172). Should be reviewable commit-by-commit.
* Add Sliding Sync `/sync/e2ee` endpoint for To-Device messages (#17167)Eric Eastwood2024-05-233-10/+411
| | | | | | | | | | | This is being introduced as part of Sliding Sync but doesn't have any sliding window component. It's just a way to get E2EE events without having to sit through a big initial sync (`/sync` v2). And we can avoid encryption events being backed up by the main sync response or vice-versa. Part of some Sliding Sync simplification/experimentation. See [this discussion](https://github.com/element-hq/synapse/pull/17167#discussion_r1610495866) for why it may not be as useful as we thought.

* Bring auto-accept invite logic into Synapse (#17147)devonh2024-05-216-1/+250
| | | | | | | | | | | | | | This PR ports the logic from the [synapse_auto_accept_invite](https://github.com/matrix-org/synapse-auto-accept-invite) module into synapse. I went with the naive approach of injecting the "module" next to where third party modules are currently loaded. If there is a better/preferred way to handle this, I'm all ears. It wasn't obvious to me if there was a better location to add this logic that would cleanly apply to all incoming invite events.

| | | | | | | | | | | | | | | | | | | | ... when workers are unreachable, etc. Fixes https://github.com/element-hq/synapse/issues/17117. The general principle is just to make sure that we propagate any exceptions to the JsonResource, so that we return an error code to the sending server. That means that the sending server no longer considers the message safely sent, so it will retry later. In the issue, Erik mentions that an alternative solution would be to persist the to-device messages into a table so that they can be retried. This might be an improvement for performance, but even if we did that, we still need this mechanism, since we might be unable to reach the database. So, if we want to do that, it can be a later follow-up. --------- Co-authored-by: Erik Johnston <erik@matrix.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Weakness in auth chain indexing allows DoS from remote room members through disk fill and high CPU usage. A remote Matrix user with malicious intent, sharing a room with Synapse instances before 1.104.1, can dispatch specially crafted events to exploit a weakness in how the auth chain cover index is calculated. This can induce high CPU consumption and accumulate excessive data in the database of such instances, resulting in a denial of service. Servers in private federations, or those that do not federate, are not affected.

* | Use receipts `event_stream_ordering` instead of joins (#17032)Nick Mills-Barrett2024-04-122-19/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resurrecting https://github.com/matrix-org/synapse/pull/13918. This should reduce IOPs incurred by joining to the events table to lookup stream ordering, which happens in many receipt handling code paths. Like the previous PR I believe sufficient time has passed between the original migration in DB schema 72 and now to merge this as-is. It's highly unlikely that both the migration is still ongoing AND (active) users still have any receipts prior to that date. In the unlikely event there is a receipt without a populated `event_stream_ordering` synapse will behave just as it does now when receipts exist for events that don't (yet): for push action calculation the receipts are just ignored. I've removed the validation on event IDs as this is already covered here: https://github.com/element-hq/synapse/blob/59ceabcb9798793cd4312fdbcced4e612aeda84d/synapse/handlers/receipts.py#L189-L192

| | | | | | | | | | | | 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`.

* Improve lock performance when a lot of locks are waiting (#16840)Mathieu Velten2024-03-141-6/+9
| | | | | | | | | | | | When a lot of locks are waiting for a single lock, notifying all locks independently with `call_later` on each release is really costly and incurs some kind of async contention, where the CPU is spinning a lot for not much. The included test is taking around 30s before the change, and 0.5s after. It was found following failing tests with https://github.com/element-hq/synapse/pull/16827.

* Prevent locking up while processing batched_auth_events (#16968)Gerrit Gogel2024-03-121-9/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR aims to fix #16895, caused by a regression in #7 and not fixed by #16903. The PR #16903 only fixes a starvation issue, where the CPU isn't released. There is a second issue, where the execution is blocked. This theory is supported by the flame graphs provided in #16895 and the fact that I see the CPU usage reducing and far below the limit. Since the changes in #7, the method `check_state_independent_auth_rules` is called with the additional parameter `batched_auth_events`: https://github.com/element-hq/synapse/blob/6fa13b4f927c10b5f4e9495be746ec28849f5cb6/synapse/handlers/federation_event.py#L1741-L1743 It makes the execution enter this if clause, introduced with #15195 https://github.com/element-hq/synapse/blob/6fa13b4f927c10b5f4e9495be746ec28849f5cb6/synapse/event_auth.py#L178-L189 There are two issues in the above code snippet. First, there is the blocking issue. I'm not entirely sure if this is a deadlock, starvation, or something different. In the beginning, I thought the copy operation was responsible. It wasn't. Then I investigated the nested `store.get_events` inside the function `update`. This was also not causing the blocking issue. Only when I replaced the set difference operation (`-` ) with a list comprehension, the blocking was resolved. Creating and comparing sets with a very large amount of events seems to be problematic. This is how the flamegraph looks now while persisting outliers. As you can see, the execution no longer locks up in the above function. ![output_2024-02-28_13-59-40](https://github.com/element-hq/synapse/assets/13143850/6db9c9ac-484f-47d0-bdde-70abfbd773ec) Second, the copying here doesn't serve any purpose, because only a shallow copy is created. This means the same objects from the original dict are referenced. This fails the intention of protecting these objects from mutation. The review of the original PR https://github.com/matrix-org/synapse/pull/15195 had an extensive discussion about this matter. Various approaches to copying the auth_events were attempted: 1) Implementing a deepcopy caused issues due to builtins.EventInternalMetadata not being pickleable. 2) Creating a dict with new objects akin to a deepcopy. 3) Creating a dict with new objects containing only necessary attributes. Concluding, there is no easy way to create an actual copy of the objects. Opting for a deepcopy can significantly strain memory and CPU resources, making it an inefficient choice. I don't see why the copy is necessary in the first place. Therefore I'm proposing to remove it altogether. After these changes, I was able to successfully join these rooms, without the main worker locking up: - #synapse:matrix.org - #element-android:matrix.org - #element-web:matrix.org - #ecips:matrix.org - #ipfs-chatter:ipfs.io - #python:matrix.org - #matrix:matrix.org

* Fix joining remote rooms when a `on_new_event` callback is registered (#16973)Quentin Gliech2024-03-062-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Synapse 1.76.0, any module which registers a `on_new_event` callback would brick the ability to join remote rooms. This is because this callback tried to get the full state of the room, which would end up in a deadlock. Related: https://github.com/matrix-org/synapse-auto-accept-invite/issues/18 The following module would brick the ability to join remote rooms: ```python from typing import Any, Dict, Literal, Union import logging from synapse.module_api import ModuleApi, EventBase logger = logging.getLogger(__name__) class MyModule: def __init__(self, config: None, api: ModuleApi): self._api = api self._config = config self._api.register_third_party_rules_callbacks( on_new_event=self.on_new_event, ) async def on_new_event(self, event: EventBase, _state_map: Any) -> None: logger.info(f"Received new event: {event}") @staticmethod def parse_config(_config: Dict[str, Any]) -> None: return None ``` This is technically a breaking change, as we are now passing partial state on the `on_new_event` callback. However, this callback was broken for federated rooms since 1.76.0, and local rooms have full state anyway, so it's unlikely that it would change anything.

* Improve DB performance of calculating badge counts for push. (#16756)Erik Johnston2024-01-112-114/+147
| | | | | | | | | | | | | | | | The crux of the change is to try and make the queries simpler and pull out fewer rows. Before, there were quite a few joins against subqueries, which caused postgres to pull out more rows than necessary. Instead, let's simplify the query and do some of the filtering out in Python instead, letting Postgres do better optimizations now that it doesn't have to deal with joins against subqueries.

| | | | | | | | | | | In previous versions of authlib using `client_secret_basic` without a `client_secret` would result in an invalid auth header. Since authlib 1.3 it throws an exception. The configuration may be accepted in by very lax servers, so we don't want to deny it outright. Instead, let's default the `client_auth_method` to `none`, which does the right thing. If the config specifies `client_auth_method` and no `client_secret` then that is going to be bogus and we should reject it

* | Speed up deleting device messages (#16643)Erik Johnston2023-11-163-29/+87
| | | | | | Keeping track of a lower bound of stream ID where we've deleted everything below makes the queries much faster. Otherwise, every time we scan for rows to delete we'd re-scan across all the rows that have previously deleted (until the next table VACUUM).
* | Speed up persisting large number of outliers (#16649)Erik Johnston2023-11-162-11/+58
| | | | | | Recalculating the roots tuple every iteration could be very expensive, so instead let's do a topological sort.
* | Fix sending out of order `POSITION` over replication (#16639)Erik Johnston2023-11-163-21/+36
| | | | | | | | | | If a worker reconnects to Redis we send out the current positions of all our streams. However, if we're also trying to send out a backlog of RDATA at the same time then we can end up sending a `POSITION` with the current token *before* we've sent all the RDATA before the current token. This doesn't cause actual bugs as the receiving servers see the POSITION, fetch the relevant rows from the DB, and then ignore the old RDATA as they come in. However, this is inefficient so it'd be better if we didn't send out-of-order positions
* | More efficiently handle no-op POSITION (#16640)Erik Johnston2023-11-162-0/+52
| | | | | | | | We may receive `POSITION` commands where we already know that worker has advanced past that position, so there is no point in handling it.

* | Use _invalidate_cache_and_stream_bulk in more places. (#16616)Patrick Cloke2023-11-096-46/+70
| | | | | | | | | | This takes advantage of the new bulk method in more places to invalidate caches for many keys at once (and then to stream that over replication).
