Fix `/messages` throwing a 500 when querying for non-existent room #12683

Fix /messages throwing a 500 when querying for non-existent room

Complement test added: matrix-org/complement#369

Before: 500 internal server error

After: According to the spec, calling /messages against a non-existent room_id should throw a 403 forbidden (since you're not part of the room). This also matches the behavior before #12370 which regressed Synapse to the 500 behavior.

{
    "errcode": "M_FORBIDDEN",
    "error": "User @test:my.synapse.server not in room !dne:my.synapse.server, and room previews are disabled"
}

Todo

Add Complement test for running /messages against non-existent room_id (expect 403 forbidden)
- -> Add test to make sure /messages behaves as expected for non-existent room_id's complement#369

I've checked the usages. We never have to worry about a case where the room_id is optional.

Even though this function was annotated to always return int, it previously returned None when the room_id didn't exist in the database (rows = [(None,)] in this case).

Now we properly fallback to 0 topological_ordering when there is no room entry.

great spot, thanks!

Thanks for your diligence on this, it's much appreciated. Would it be worth a quick test case for this, given that the return-403 behaviour is specced?

Ahh, I see you've opened a complement issue. In that case, LGTM!

One changelog nit, which I'm happy to defer to you on. Otherwise LGTM, thank you!

Synapse 1.60.0rc1 (2022-05-24) ============================== This release of Synapse adds a unique index to the `state_group_edges` table, in order to prevent accidentally introducing duplicate information (for example, because a database backup was restored multiple times). If your Synapse database already has duplicate rows in this table, this could fail with an error and require manual remediation. Additionally, the signature of the `check_event_for_spam` module callback has changed. The previous signature has been deprecated and remains working for now. Module authors should update their modules to use the new signature where possible. See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1600) for more details. Features -------- - Measure the time taken in spam-checking callbacks and expose those measurements as metrics. ([\#12513](#12513)) - Add a `default_power_level_content_override` config option to set default room power levels per room preset. ([\#12618](#12618)) - Add support for [MSC3787: Allowing knocks to restricted rooms](matrix-org/matrix-spec-proposals#3787). ([\#12623](#12623)) - Send `USER_IP` commands on a different Redis channel, in order to reduce traffic to workers that do not process these commands. ([\#12672](#12672), [\#12809](#12809)) - Synapse will now reload [cache config](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#caching) when it receives a [SIGHUP](https://en.wikipedia.org/wiki/SIGHUP) signal. ([\#12673](#12673)) - Add a config options to allow for auto-tuning of caches. ([\#12701](#12701)) - Update [MSC2716](matrix-org/matrix-spec-proposals#2716) implementation to process marker events from the current state to avoid markers being lost in timeline gaps for federated servers which would cause the imported history to be undiscovered. ([\#12718](#12718)) - Add a `drop_federated_event` callback to `SpamChecker` to disregard inbound federated events before they take up much processing power, in an emergency. ([\#12744](#12744)) - Implement [MSC3818: Copy room type on upgrade](matrix-org/matrix-spec-proposals#3818). ([\#12786](#12786), [\#12792](#12792)) - Update to the `check_event_for_spam` module callback. Deprecate the current callback signature, replace it with a new signature that is both less ambiguous (replacing booleans with explicit allow/block) and more powerful (ability to return explicit error codes). ([\#12808](#12808)) Bugfixes -------- - Fix a bug introduced in Synapse 1.7.0 that would prevent events from being sent to clients if there's a retention policy in the room when the support for retention policies is disabled. ([\#12611](#12611)) - Fix a bug introduced in Synapse 1.57.0 where `/messages` would throw a 500 error when querying for a non-existent room. ([\#12683](#12683)) - Add a unique index to `state_group_edges` to prevent duplicates being accidentally introduced and the consequential impact to performance. ([\#12687](#12687)) - Fix a long-standing bug where an empty room would be created when a user with an insufficient power level tried to upgrade a room. ([\#12696](#12696)) - Fix a bug introduced in Synapse 1.30.0 where empty rooms could be automatically created if a monthly active users limit is set. ([\#12713](#12713)) - Fix push to dismiss notifications when read on another client. Contributed by @SpiritCroc @ Beeper. ([\#12721](#12721)) - Fix poor database performance when reading the cache invalidation stream for large servers with lots of workers. ([\#12747](#12747)) - Delete events from the `federation_inbound_events_staging` table when a room is purged through the admin API. ([\#12770](#12770)) - Give a meaningful error message when a client tries to create a room with an invalid alias localpart. ([\#12779](#12779)) - Fix a bug introduced in 1.43.0 where a file (`providers.json`) was never closed. Contributed by @arkamar. ([\#12794](#12794)) - Fix a long-standing bug where finished log contexts would be re-started when failing to contact remote homeservers. ([\#12803](#12803)) - Fix a bug, introduced in Synapse 1.21.0, that led to media thumbnails being unusable before the index has been added in the background. ([\#12823](#12823)) Updates to the Docker image --------------------------- - Fix the docker file after a dependency update. ([\#12853](#12853)) Improved Documentation ---------------------- - Fix a typo in the Media Admin API documentation.

This breaks compatibility with Element Android 1.2.0 and earlier: users of those clients will be unable to send read receipts.
