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
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 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.

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.

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.

* WIP Event rejection
* Still send back errors for rejected events
Instead, discard them at the federationapi /send layer rather than
re-implementing checks at the clientapi/PerformJoin layer.
* Implement rejected events
Critically, rejected events CAN cause state resolution to happen
as it can merge forks in the DAG. This is fine, _provided_ we
do not add the rejected event when performing state resolution,
which is what this PR does. It also fixes the error handling
when NotAllowed happens, as we were checking too early and needlessly
handling NotAllowed in more than one place.
* Update test to match reality
* Modify InputRoomEvents to no longer return an error
Errors do not serialise across HTTP boundaries in polylith mode,
so instead set fields on the InputRoomEventsResponse. Add `Err()`
function to make the API shape basically the same.
* Remove redundant returns; linting
* Update blacklist
* Remove QueryBulkStateContent from current state server
Expected fail due to db impl not existing
* Implement query bulk state content
* Fix up rejecting invites over federation
* Fix bulk content marshalling
* Move currentstateserver API to roomserver
Stub out DB functions for now, nothing uses the roomserver version yet.
* Allow it to startup
* Implement some current-state-server storage interface functions
* Add missing package
* Per-room input mutex
* GetMembership should use transaction when assigning state key NID
* Actually use writer transactions rather than ignoring them
* Limit per-room mutexes to Postgres
* Flip the check in InputRoomEvents
* Emit redacted_event from the roomserver when redactions are validated
- Consume them in the currentstateserver and act accordingly.
- Add integration test for the roomserver to check that injecting
`m.room.redaction` events result in `redacted_event` being emitted.
* Linting
* Ignore events that redact themselves
* Use content_value instead of membership
* Fix build
* Replace publicroomsapi with a combination of clientapi/roomserver/currentstateserver
- All public rooms paths are now handled by clientapi
- Requests to (un)publish rooms are sent to the roomserver via `PerformPublish`
which are stored in a new `published_table.go`
- Requests for public rooms are handled in clientapi by:
* Fetch all room IDs which are published using `QueryPublishedRooms` on the roomserver.
* Apply pagination parameters to the slice.
* Do a `QueryBulkStateContent` request to the currentstateserver to pull out
required state event *content* (not entire events).
* Aggregate and return the chunk.
Mostly but not fully implemented (DB queries on currentstateserver are missing)
* Fix pq query
* Make postgres work
* Make sqlite work
* Fix tests
* Unbreak pagination tests
* Linting
* Initial cut for backfilling
The syncserver now asks the roomserver via QueryBackfill (which already
existed to *handle* backfill requests) which then makes federation requests
via gomatrixserverlib.RequestBackfill.
Currently, tests fail on subsequent /messages requests because we don't know
which servers are in the room, because we are unable to get state snapshots
from a backfilled event because that code doesn't exist yet.
* WIP backfill, doesn't work
* Make initial backfill pass checks
* Persist backfilled events with state snapshots
* Remove debug lines
* Linting
* Review comments
* Update gomatixserverlib
* Try to build invite stripped state if not given to us
* SendInvite improvements
* Transpose invite_room_state into invite_state.events for sync API
* Remove syncapi debugging output
* Use RespInviteV2
* Update gomatrixserverlib
* Send the invite event as a normal roomserver event too, for incorporating into room (should this be done by the roomserver automatically for invite inputs?)
* Federation sender use invite_room_state, room server try to insert membership state
* Check supported room versions on the invite endpoint
* Prevent roomserver query API from trying to handle requests for stub rooms
* Adding a nolint
* Replace IsRoomStub with RoomNIDExcludingStubs, fix query API to use that instead
* Review comments
* Start converting v1 invite endpoint to v2
* Update gomatrixserverlib
* Early federationsender code for sending invites

* Update to latest go-sqlite-js version
* Replace prometheus with a stub. sigh
* Hard-code a config and don't use opentracing
* Latest go-sqlite3-js version
* Generate a key for now
* Listen for fetch traffic rather than HTTP
* Latest hacks for js
* libp2p support
* More libp2p
* Fork gjson to allow us to enforce auth checks as before
Previously, all events would come down redacted because the hash
checks would fail. They would fail because sjson.DeleteBytes didn't
remove keys not used for hashing. This didn't work because of a build
tag which included a file which no-oped the index returned.
See https://github.com/tidwall/gjson/issues/157
When it's resolved, let's go back to mainline.
* Use gjson@1.6.0 as it fixes https://github.com/tidwall/gjson/issues/157
* Use latest gomatrixserverlib for sig checks
* Fix a bug which could cause exclude_from_sync to not be set
Caused when sending events over federation.
* Use query variadic to make lookups actually work!
* Latest gomatrixserverlib
* Add notes on getting p2p up and running
Partly so I don't forget myself!
* refactor: Move p2p specific stuff to cmd/dendritejs
This is important or else the normal build of dendrite will fail
because the p2p libraries depend on syscall/js which doesn't work
on normal builds.
Also, clean up main.go to read a bit better.
* Update ho-http-js-libp2p to return errors from RoundTrip
* Add an LRU cache around the key DB
We actually need this for P2P because otherwise we can *segfault*
with things like: "runtime: unexpected return pc for runtime.handleEvent"
where the event is a `syscall/js` event, caused by spamming sql.js
caused by "Checking event signatures for 14 events of room state" which
hammers the key DB repeatedly in quick succession.
Using a cache fixes this, though the underlying cause is probably a bug
in the version of Go I'm on (1.13.7)
* breaking: Add Tracing.Enabled to toggle whether we do opentracing
Defaults to false, which is why this is a breaking change. We need
this flag because WASM builds cannot do opentracing.
* Start adding conditional builds for wasm to handle lib/pq
The general idea here is to have the wasm build have a `NewXXXDatabase`
that doesn't import any postgres package and hence we never import
`lib/pq`, which doesn't work under WASM (undefined `userCurrent`).
* Remove lib/pq for wasm for syncapi
* Add conditional building to remaining storage APIs
* Update build script to set env vars correctly for dendritejs
* sqlite bug fixes
* Docs
* Add a no-op main for dendritejs when not building under wasm
* Use the real prometheus, even for WASM
Instead, the dendrite-sw.js must mock out `process.pid` and
`fs.stat` - which must invoke the callback with an error (e.g `EINVAL`)
in order for it to work:
```
global.process = {
pid: 1,
};
global.fs.stat = function(path, cb) {
cb({
code: "EINVAL",
});
}
```
* Linting
