The previous version was getting **ALL** membership events (as
`ClientEvents`, so going through `NewEventFromTrustedJSONWithID`) for a
given room.
Now we are querying only locally joined users as `ClientEvents`, which
should **significantly** reduce allocations.
Take for example a large room with 2k membership events, but only 1
local user - avoiding 1999 `NewEventFromTrustedJSONWithID` calls just to
calculate the `roomSize` which we can also query by other means.
This is also getting called for every `OutputRoomEvent` in the userAPI.
Benchmark with 1 local user and 100 remote users.

When we're adding state to the database, we check which eventNIDs are
already in a block, if we already have that eventNID, we remove it from
the list. In its current form we would skip over eventNIDs in the case
we already found a match (we're decrementing `i` twice)
My theory is, that when we later get the state blocks, we are receiving
"too many" eventNIDs (well, yea, we stored too many), which may or may
not can result in state resets when comparing different state snapshots.
(e.g. when adding state we stored a eventNID by accident because we
skipped it, later we add more state and are not adding it because we
don't skip it)
This should fix two issues with backfilling:
1. right after creating and joining a room over federation, we are doing
a `/backfill` request, which would return redacted events, because the
`authEvents` are empty. Even though the spec states that, in the absence
of a history visibility event, it should be handled as `shared`.
2. `gomatrixserverlib: unsupported room version ''` - because, well, we
were never setting the `roomInfo` field..
They are fundamentally different concepts, so should be represented as
such. Proto events are exchanged in /make_xxx calls over federation, and
made as "fledgling" events in /createRoom and general event sending.
*Building* events is a reasonably complex VERSION SPECIFIC process which
needs amongst other things, auth event providers, prev events, signing
keys, etc.
Requires https://github.com/matrix-org/gomatrixserverlib/pull/379
Requires https://github.com/matrix-org/gomatrixserverlib/pull/376
This has numerous upsides:
- Less type casting to `*Event` is required.
- Making Dendrite work with `PDU` interfaces means we can swap out Event
impls more easily.
- Tests which represent weird event shapes are easier to write.
Part of a series of refactors on GMSL.
This removes `PerformError`, which was needed when we still had
polylith.
This removes quite a bunch of
```go
if err != nil {
return err
}
if err := res.Error; err != nil {
return err.JSONResponse()
}
```
Hopefully can be read commit by commit. [skip ci]
We only use it in a few places currently, enough to get things to
compile and run. We should be using it in much more places.
Similarly, in some places we cast []PDU back to []*Event, we need to not
do that. Likewise, in some places we cast PDU to *Event, we need to not
do that. For now though, hopefully this is a start.
Replaced with types.HeaderedEvent _for now_. In reality we want to move
them all to gmsl.Event and only use HeaderedEvent when we _need_ to
bundle the version/event ID with the event (seriailsation boundaries,
and even then only when we don't have the room version).
Requires https://github.com/matrix-org/gomatrixserverlib/pull/373
Adds tests for `QueryRestrictedJoinAllowed`, `IsServerAllowed` and
`PerformRoomUpgrade`. Refactors the `QueryRoomVersionForRoom` method to
accept a string and return a `gmsl.RoomVersion` instead of req/resp
structs.
Adds some more caching for `GetStateEvent`
This should also fix#2912 by ignoring state events belonging to other
users.
As outlined in https://github.com/matrix-org/gomatrixserverlib/pull/368
The main change Dendrite side is that `RoomVersion` no longer has any
methods on it. Instead, you need to bounce via `gmsl.GetRoomVersion`.
It's very interesting to see where exactly Dendrite cares about this.
For some places it's creating events (fine) but others are way more
specific. Those areas will need to migrate to GMSL at some point.
Threepid seems to be pretty out of date, several missing endpoints.
Should also fix#3037, where we were still listening on the `/unstable`
prefix, while Element Web uses `/r0`
Contains a breaking change, since the endpoints `/_dendrite/admin/evacuateRoom/{roomID}` and `/_dendrite/admin/evacuateUser/{userID}` are now using `POST` instead of `GET`
Preparations to actually remove/replace `BaseDendrite`.
Quite a few changes:
- SyncAPI accepts an `fulltext.Indexer` interface (fulltext is removed
from `BaseDendrite`)
- Caches are removed from `BaseDendrite`
- Introduces a `Router` struct (likely to change)
- also fixes#2903
- Introduces a `sqlutil.ConnectionManager`, which should remove
`base.DatabaseConnection` later on
- probably more
This should deflake UTs and be more correct in terms of getting
`Events`.
`Events` tries to fetch the event from the cache first and may get an
unredacted event from it, while it should already be redacted.
We need to check the redaction PL in Dendrite, if we do it in GMSL, we
end up not sending the event to the output stream because it will be
rejected.

This PR changes the following:
- `StoreEvent` now only stores an event (and possibly prev event),
instead of also doing redactions
- Adds a `MaybeRedactEvent` (pulled out from `StoreEvent`), which should
be called after storing events
- a few other things
This PR changes a few things:
- It pulls out the creation of several NIDs from the `StoreEvent`
function to make the functions more reusable
- Uses more caching when using those NIDs to avoid DB round trips
This removes most of the code used for polylith/API mode.
This removes the `/api` internal endpoints entirely.
Binary size change roughly 5%:

Should fix the following issues or make a lot less worse when using
Postgres:
The main issue behind #2911: The client gives up after a certain time,
causing a cascade of context errors, because the response couldn't be
built up fast enough. This mostly happens on accounts with many rooms,
due to the inefficient way we're getting recent events and current state
For #2777: The queries for getting the membership events for history
visibility were being executed for each room (I think 185?), resulting
in a whooping 2k queries for membership events. (Getting the
statesnapshot -> block nids -> actual wanted membership event)
Both should now be better by:
- Using a LATERAL join to get all recent events for all joined rooms in
one go (TODO: maybe do the same for room summary and current state etc)
- If we're lazy loading on initial syncs, we're now not getting the
whole current state, just to drop the majority of it because we're lazy
loading members - we add a filter to exclude membership events on the
first call to `CurrentState`.
- Using an optimized query to get the membership events needed to
calculate history visibility

This adds Sytest and Complement coverage reporting to the nightly
scheduled CI runs.
Fixes a few API mode related issues as well, since we seemingly never
really ran them with Complement.
Also fixes a bug related to device list changes: When we pass in an
empty `newlyLeftRooms` slice, we got a list of all currently joined
rooms with the corresponding members. When we then got the
`newlyJoinedRooms`, we wouldn't update the `changed` slice, because we
already got the user from the `newlyLeftRooms` query. This is fixed by
simply ignoring empty `newlyLeftRooms`.
This PR implements
[MSC3904](https://github.com/matrix-org/matrix-spec-proposals/pull/3904).
This PR is almost identical to #2781 but this PR is also filed well
technically 1 day before the MSC passes FCP but well everyone knows this
MSC is expected to have passed FCP on monday so im refiling this change
today on saturday as i was doing prep work for monday. I assume that
this PR wont be counted as clogging the queue since by the next time i
expect to be a work day for this project this PR will be implementing an
FCP passed disposition merge MSC.
Also as for the lack of tests i belive that this simple change does not
need to pass new tests due to that these tests are expected to already
have been passed by the successful use of Dendrite with Room version 10
already.

This adds a new admin endpoint `/_dendrite/admin/purgeRoom/{roomID}`. It
completely erases all database entries for a given room ID.
The roomserver will start by clearing all data for that room and then
will generate an output event to notify downstream components (i.e. the
sync API and federation API) to do the same.
It does not currently clear media and it is currently not implemented
for SQLite since it relies on SQL array operations right now.

Needs https://github.com/matrix-org/sytest/pull/1315, as otherwise the
membership events aren't persisted yet when hitting `/state` after
kicking guest users.
Makes the following tests pass:
```
Guest users denied access over federation if guest access prohibited
Guest users are kicked from guest_access rooms on revocation of guest_access
Guest users are kicked from guest_access rooms on revocation of guest_access over federation
```
Todo (in a follow up PR):
- Restrict access to CS API Endpoints as per
https://spec.matrix.org/v1.4/client-server-api/#client-behaviour-14

The stale device lists table might contain entries for users we don't
share a room with anymore. This now asks the roomserver about left users
and removes those entries from the table.

Basically enables us to use `test.WithAllDatabases` when testing
internal HTTP APIs, as this would otherwise result in Prometheus
complaining about already registered metric names.
Makes the following tests pass
```
/upgrade moves remote aliases to the new room
Local and remote users' homeservers remove a room from their public directory on upgrade
```
This optimizes history visibility checks by (mostly) avoiding database
hits.
Possibly solves https://github.com/matrix-org/dendrite/issues/2777

Adds `PUT
/_matrix/client/v3/directory/list/appservice/{networkId}/{roomId}` and
`DELTE
/_matrix/client/v3/directory/list/appservice/{networkId}/{roomId}`
support, as well as the ability to filter `/publicRooms` on networkID
and including all networks.
This prevents us from holding onto durable consumers indefinitely for
rooms that have long since turned inactive, since they do have a bit of
a processing overhead in the NATS Server. If we clear up a consumer and
then a room becomes active again, the consumer gets recreated as needed.
The threshold is set to 24 hours for now, we can tweak it later if needs
be.
Fixes `outliers whose auth_events are in a different room are correctly
rejected`, by validating that auth events are all from the same room and
not using rejected events for event auth.
Sytest was using a wrong `history_visibility` for `invited`
(https://github.com/matrix-org/sytest/pull/1303), so `invited` was
passing for the wrong reason (-> defaulted to `shared`, as `invite`
wasn't understood).
This change now handles missing events like Synapse, if a server isn't
allowed to see the event, it gets a redacted version of it, making the
`get_missing_events` tests pass.
This should hopefully fix an entire class of problems where components
downstream from the roomserver (i.e. the sync API) could just lose a
whole bunch of state after a rewrite operation like a federated join.
The root of the bug is that we set `RewritesState` in the output event
which instructs downstream components to purge their copy of any room
state, but then didn't send the entire state snapshot in
`adds_state_event_ids` so the downstream state ends up being incomplete
as a result.
