Synapse previously did not correctly cap the max depth of an event to
the max canonical json int. This can cause ordering issues for any
events that were sent locally at the time.
This background update goes and correctly caps the topological ordering
to the new `MAX_DEPTH`.

This PR makes a few radical changes to media. This now stores the SHA256
hash of each file stored in the database (excluding thumbnails, more on
that later). If a set of media is quarantined, any additional uploads of
the same file contents or any other files with the same hash will be
quarantined at the same time.
Currently this does NOT:
- De-duplicate media, although a future extension could be to do that.
- Run any background jobs to identify the hashes of older files. This
could also be a future extension, though the value of doing so is
limited to combat the abuse of recent media.
- Hash thumbnails. It's assumed that thumbnails are parented to some
form of media, so you'd likely be wanting to quarantine the media and
the thumbnail at the same time.

This background DB delta removes the old state group deletion background
update from the `background_updates` table if it exists.
The `delete_unreferenced_state_groups_bg_update` update should only
exist in that table if a homeserver ran v1.126.0rc1/v1.126.0rc2, and
rolled back or forward to any other version of Synapse before letting
the update finish.

This PR fixes #18154 to avoid de-deltaing state groups which resulted in
DB size temporarily increasing until the DB was `VACUUM`'ed. As a
result, less state groups will get deleted now.
It also attempts to improve performance by not duplicating work when
processing state groups it has already processed in previous iterations.

Currently we don't really have anything that stops us from deleting
state groups when an in-flight event references it. This is a fairly
rare race currently, but we want to be able to more aggressively delete
state groups so it is important to address this to ensure that the
database remains valid.
This implements the locking, but doesn't actually use it.
See the class docstring of the new data store for an explanation for how
this works.

Added in #17912, was a bad copy and paste.
|
| |
|
|
| |
This was due to a missing index, which meant that deleting previous
connections associated with the device and `conn_id` took a long time.

To work around the fact that,
pre-https://github.com/element-hq/synapse/pull/17903, our database may
have old one-time-keys that the clients have long thrown away the
private keys for, we want to delete OTKs that look like they came from
libolm.
To spread the load a bit, without holding up other background database
updates, we use a scheduled task to do the work.
|
| |
|
|
| |
As we're now using it in the sync APIs to get state changes within a
room
|
| |
|
|
|
|
|
|
| |
Currently, one-time-keys are issued in a somewhat random order. (In
practice, they are issued according to the lexicographical order of
their key IDs.) That can lead to a situation where a client gives up
hope of a given OTK ever being used, whilst it is still on the server.

rejoining a room) (#17835)
Reset `sliding_sync_membership_snapshots` -> `forgotten` status when
membership changes (like rejoining a room).
Fix https://github.com/element-hq/synapse/issues/17781
### What was the problem before?
Previously, if someone used `/forget` on one of their rooms, it would
update `sliding_sync_membership_snapshots` as expected but when someone
rejoined the room (or had any membership change), the upsert didn't
overwrite and reset the `forgotten` status so it remained `forgotten`
and invisible down the Sliding Sync endpoint.

For rooms with a name we can skip fetching a full room summary, as we
don't need to calculate heroes, and instead just fetch the room counts
directly.
This also changes things to not return counts and heroes for non-joined
rooms. For left/banned rooms we were returning zero values anyway, and
for invite/knock rooms we don't really want to leak such information
(even if some of is included in the stripped state).

I thought ruff check would also format, but it doesn't.
This runs ruff format in CI and dev scripts. The first commit is just a
run of `ruff format .` in the root directory.

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)

### 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
https://github.com/element-hq/synapse/commit/76b5a576eb363496315dfd39510cad7d02b0fc73
- [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)

Both of these are equivalent and work in SQLite and Postgres

(SELECT membership FROM room_memberships WHERE event_id = ?),
(SELECT stream_ordering FROM events WHERE event_id = ?),

)
)
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 != ?
ON CONFLICT (room_id, user_id)
DO UPDATE SET
membership_event_id = EXCLUDED.membership_event_id,
membership = EXCLUDED.membership,
event_stream_ordering = EXCLUDED.event_stream_ordering,
{", ".join(f"{key} = EXCLUDED.{key}" for key in insert_keys)}
```
Option 2:
```sql
INSERT INTO sliding_sync_non_join_memberships
(room_id, user_id, membership_event_id, membership, event_stream_ordering, {", ".join(insert_keys)})
SELECT
column1 as room_id,
column2 as user_id,
column3 as membership_event_id,
column4 as membership,
column5 as event_stream_ordering,
{", ".join("column" + str(i) for i in range(6, 6 + len(insert_keys)))}
FROM (
VALUES (
?, ?, ?,
(SELECT membership FROM room_memberships WHERE event_id = ?),
(SELECT stream_ordering FROM events WHERE event_id = ?),
{", ".join("?" for _ in insert_values)}

) as v
WHERE membership != ?
ON CONFLICT (room_id, user_id)

membership = EXCLUDED.membership,
event_stream_ordering = EXCLUDED.event_stream_ordering,

If we don't need the `membership` condition, we could use:
```sql
INSERT INTO sliding_sync_non_join_memberships

VALUES (
?, ?, ?,

If the stream ID in the unconverted table is ahead of the device lists
ID gen, then it can break all /sync requests that had an ID from ahead
of the table.
The fix is to make sure we add the unconverted table to the list of
tables we check at start up.

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.

This table was no longer used, except for a background process
which purged old entries in it.

This splits thinsg into two queries, but most of the time we won't have
new event backwards extremities so this shouldn't actually add an extra
RTT for the majority of cases.
Note this removes the check for events with no prev events, but that was
part of MSC2716 work that has since been removed.

Updates the database schema to require a thread_id (by adding a

(#15280)
This makes it so that we rely on the `device_id` to delete pushers on logout,
instead of relying on the `access_token_id`. This ensures we're not removing
pushers on token refresh, and prepares for a world without access token IDs
(also known as the OIDC).
This actually runs the `set_device_id_for_pushers` background update, which
was forgotten in #13831.
Note that for backwards compatibility it still deletes pushers based on the
`access_token` until the background update finishes.

Specifically this adds the column to `current_state_events`,

is regularly joined with the `events` table to get the stream ordering
and denormalising this into each table will yield significant query
performance improvements once used.

* Add comment in schema file explaining new denormalised columns
* Add triggers to enforce consistency of `event_stream_ordering` columns
* Re-order purge room tables to account for foreign keys

is regularly joined with the `events` table to get the stream ordering

if a Synapse deployment upgraded (from < 1.62.0 to >= 1.70.0) then it
is possible for schema deltas to run before background updates causing
drift in the database schema due to:
1. A delta registered a background update to create an index.
2. A delta dropped the above index if it exists (but it yet exist won't since
the background job hasn't run).
3. The code assumed the index was dropped.
To fix this we:
1. Cancel the background update which could create the index.
2. Drop the index again.
3. Drop a related index which is dropped by the background update.

Due to the various fixes to the StreamChangeCache it is not

When a local device list change is added to
`device_lists_changes_in_room`, the `converted_to_destinations` flag is
set to `FALSE` and the `_handle_new_device_update_async` background
process is started. This background process looks for unconverted rows
in `device_lists_changes_in_room`, copies them to
`device_lists_outbound_pokes` and updates the flag.
To update the `converted_to_destinations` flag, the database performs a
`DELETE` and `INSERT` internally, which fragments the table. To avoid
this, track unconverted rows using a `(stream ID, room ID)` position
instead of the flag.
From now on, the `converted_to_destinations` column indicates rows that
need converting to outbound pokes, but does not indicate whether the
conversion has already taken place.
Closes #14037.

PostgreSQL may underestimate the number of distinct `room_id`s in
`event_search`, which can cause it to use table scans for queries for
multiple rooms.
Fix this by setting `n_distinct` on the column.

underlying DB. (#11635)
Support a unified search query syntax which leverages more of the full-text
search of each database supported by Synapse.
Supports, with the same syntax across Postgresql 11+ and Sqlite:
- quoted "search terms"
- `AND`, `OR`, `-` (negation) operators
- Matching words based on their stem, e.g. searches for "dog" matches
documents containing "dogs".
This is achieved by
- If on postgresql 11+, pass the user input to `websearch_to_tsquery`
- If on sqlite, manually parse the query and transform it into the sqlite-specific
query syntax.
Note that postgresql 10, which is close to end-of-life, falls back to using
`phraseto_tsquery`, which only supports a subset of the features.
Multiple terms separated by a space are implicitly ANDed.
Note that:
1. There is no escaping of full-text syntax that might be supported by the database;
e.g. `NOT`, `NEAR`, `*` in sqlite. This runs the risk that people might discover this
as accidental functionality and depend on something we don't guarantee.
2. English text is assumed for stemming. To support other languages, either the target
language needs to be known at the time of indexing the message (via room metadata,
or otherwise), or a separate index for each language supported could be created.

When retrieving counts of notifications segment the results based on the
thread ID, but choose whether to return them as individual threads or as
a single summed field by letting the client opt-in via a sync flag.
The summarization code is also updated to be per thread, instead of per
room.

c.f. #12993 (comment), point 3
This stores all device list updates that we receive while partial joins are ongoing, and processes them once we have the full state.
Note: We don't actually process the device lists in the same ways as if we weren't partially joined. Instead of updating the device list remote cache, we simply notify local users that a change in the remote user's devices has happened. I think this is safe as if the local user requests the keys for the remote user and we don't have them we'll simply fetch them as normal.

Adds a `thread_id` column to the `event_push_actions`, `event_push_actions_staging`,
and `event_push_summary` tables. This will notifications to be segmented by the thread
in a future pull request. The `thread_id` column stores the root event ID or the special
value `"main"`.
The `thread_id` column for `event_push_actions` and `event_push_summary` is
backfilled with `"main"` for all existing rows. New entries into `event_push_actions`
and `event_push_actions_staging` will get the proper thread ID.
`receipts_linearized` and `receipts_graph` also gain a `thread_id` column, which is similar,
except `NULL` is a special value meaning the receipt is "unthreaded".
See MSC3771 and MSC3773 for where this data will be useful.

Partial indices have been supported since SQLite 3.8, but Synapse
now requires >= 3.27, so we can enable support for them.
This requires rebuilding previous indices which were partial on

* Remove incorrect migration file from `state` logical DB
The table `ex_outlier_stream` is part of the `main` logical DB; it
should not have been created in the `state` logical DB. We remove this
migration now as a tidy-up.
Note: we cannot `DROP TABLE IF EXISTS ex_outlier_stream` in a new
migration, because some (most) instances of Synapse host both of these
logical DBs on the same DB cluster.

Fixes #11887 hopefully.
The core change here is that `event_push_summary` now holds a summary of counts up until a much more recent point, meaning that the range of rows we need to count in `event_push_actions` is much smaller.
This needs two major changes:
1. When we get a receipt we need to recalculate `event_push_summary` rather than just delete it
2. The logic for deleting `event_push_actions` is now divorced from calculating `event_push_summary`.
In future it would be good to calculate `event_push_summary` while we persist a new event (it should just be a case of adding one to the relevant rows in `event_push_summary`), as that will further simplify the get counts logic and remove the need for us to periodically update `event_push_summary` in a background job.

* Remove redundant references to `event_edges.room_id`
We don't need to care about the room_id here, because we are already checking
the event id.
* Clean up the event_edges table
We make a number of changes to `event_edges`:
* We give the `room_id` and `is_state` columns defaults (null and false
respectively) so that we can stop populating them.
* We drop any rows that have `is_state` set true - they should no longer
exist.
* We drop any rows that do not exist in `events` - these should not exist
either.
* We drop the old unique constraint on all the colums, which wasn't much use.
* We create a new unique index on `(event_id, prev_event_id)`.
* We add a foreign key constraint to `events`.
These happen rather differently depending on whether we are on Postgres or
SQLite. For SQLite, we just rebuild the whole table, copying only the rows we
want to keep. For Postgres, we try to do things in the background as much as
possible.
* Stop populating `event_edges.room_id` and `is_state`
We can just rely on the defaults.

This is a first step in dealing with #7721.
The idea is basically that rather than calculating the full set of users a device list update needs to be sent to up front, we instead simply record the rooms the user was in at the time of the change. This will allow a few things:
1. we can defer calculating the set of remote servers that need to be poked about the change; and
2. during `/sync` and `/keys/changes` we can avoid also avoid calculating users who share rooms with other users, and instead just look at the rooms that have changed.
However, care needs to be taken to correctly handle server downgrades. As such this PR writes to both `device_lists_changes_in_room` and the `device_lists_outbound_pokes` table synchronously. In a future release we can then bump the database schema compat version to `69` and then we can assume that the new `device_lists_changes_in_room` exists and is handled.
There is a temporary option to disable writing to `device_lists_outbound_pokes` synchronously, allowing us to test the new code path does work (and by implication upgrading to a future release and downgrading to this one will work correctly).
Note: Ideally we'd do the calculation of room to servers on a worker (e.g. the background worker), but currently only master can write to the `device_list_outbound_pokes` table.

Switching to a sequence means there's no need to track `last_txn` on the
AS state table to generate new TXN IDs. This also means that there is
no longer contention between the AS scheduler and AS handler on updates
to the `application_services_state` table, which will prevent serialization
errors during the complete AS txn transaction.

When we get a partial_state response from send_join, store information in the
database about it:
* store a record about the room as a whole having partial state, and stash the
list of member servers too.
* flag the join event itself as having partial state
* also, for any new events whose prev-events are partial-stated, note that
they will *also* be partial-stated.
We don't yet make any attempt to interpret this data, so API calls (and a bunch
of other things) are just going to get incorrect data.

(MSC2716) (#10975)
Resolve and share `state_groups` for all historical events in batch. This also helps for showing the appropriate avatar/displayname in Element and will work whenever `/messages` has one of the historical messages as the first message in the batch.
This does have the flaw where if you just insert a single historical event somewhere, it probably won't resolve the state correctly from `/messages` or `/context` since it will grab a non historical event above or below with resolved state which never included the historical state back then. For the same reasions, this also does not work in Element between the transition from actual messages to historical messages. In the Gitter case, this isn't really a problem since all of the historical messages are in one big lump at the beginning of the room.
For a future iteration, might be good to look at `/messages` and `/context` to additionally add the `state` for any historical messages in that batch.
---
How are the `state_groups` shared? To illustrate the `state_group` sharing, see this example:
**Before** (new `state_group` for every event 😬, very inefficient):

* Make historical messages available to federated servers
Part of MSC2716: https://github.com/matrix-org/matrix-doc/pull/2716
Follow-up to https://github.com/matrix-org/synapse/pull/9247
* Debug message not available on federation
* Add base starting insertion point when no chunk ID is provided
* Fix messages from multiple senders in historical chunk
Follow-up to https://github.com/matrix-org/synapse/pull/9247
Part of MSC2716: https://github.com/matrix-org/matrix-doc/pull/2716
---
Previously, Synapse would throw a 403,
`Cannot force another user to join.`,
because we were trying to use `?user_id` from a single virtual user
which did not match with messages from other users in the chunk.
* Remove debug lines
* Messing with selecting insertion event extremeties
* Move db schema change to new version
* Add more better comments
* Make a fake requester with just what we need
See https://github.com/matrix-org/synapse/pull/10276#discussion_r660999080
* Store insertion events in table
* Make base insertion event float off on its own
See https://github.com/matrix-org/synapse/pull/10250#issuecomment-875711889
Conflicts:
synapse/rest/client/v1/room.py
* Validate that the app service can actually control the given user
See https://github.com/matrix-org/synapse/pull/10276#issuecomment-876316455
Conflicts:
synapse/rest/client/v1/room.py
* Add some better comments on what we're trying to check for
* Continue debugging
* Share validation logic
* Add inserted historical messages to /backfill response
* Remove debug sql queries

* Clean up PR
* Rename insertion_event_id to just event_id
* Add some better sql comments
* More accurate description
* Add changelog
* Make it clear what MSC the change is part of
* Add more detail on which insertion event came through
* Address review and improve sql queries
* Only use event_id as unique constraint
* Fix test case where insertion event is already in the normal DAG
* Remove debug changes
* Add support for MSC2716 marker events
* Process markers when we receive it over federation
* WIP: make hs2 backfill historical messages after marker event
* hs2 to better ask for insertion event extremity
But running into the `sqlite3.IntegrityError: NOT NULL constraint failed: event_to_state_groups.state_group`
error
* Add insertion_event_extremities table
* Switch to chunk events so we can auth via power_levels
Previously, we were using `content.chunk_id` to connect one
chunk to another. But these events can be from any `sender`
and we can't tell who should be able to send historical events.
We know we only want the application service to do it but these
events have the sender of a real historical message, not the
application service user ID as the sender. Other federated homeservers
also have no indicator which senders are an application service on
the originating homeserver.
So we want to auth all of the MSC2716 events via power_levels
and have them be sent by the application service with proper
PL levels in the room.
* Switch to chunk events for federation
* Add unstable room version to support new historical PL
* Messy: Fix undefined state_group for federated historical events

Per discussion with @erikjohnston,
https://matrix.to/#/!UytJQHLQYfvYWsGrGY:jki.re/$12bTUiObDFdHLAYtT7E-BvYRp3k_xv8w0dUQHibasJk?via=jki.re&via=matrix.org
* Make it possible to get the room_version with txn
* Allow but ignore historical events in unsupported room version
See https://github.com/matrix-org/synapse/pull/10245#discussion_r675592489
We can't reject historical events on unsupported room versions because homeservers without knowledge of MSC2716 or the new room version don't reject historical events either.
Since we can't rely on the auth check here to stop historical events on unsupported room versions, I've added some additional checks in the processing/persisting code (`synapse/storage/databases/main/events.py` -> `_handle_insertion_event` and `_handle_chunk_event`). I've had to do some refactoring so there is method to fetch the room version by `txn`.
* Move to unique index syntax
See https://github.com/matrix-org/synapse/pull/10245#discussion_r675638509
* High-level document how the insertion->chunk lookup works
* Remove create_event fallback for room_versions
See https://github.com/matrix-org/synapse/pull/10245/files#r677641879
* Use updated method name

The postgres statistics collector sometimes massively underestimates the
number of distinct state groups are in the `state_groups_state`, which
can cause postgres to use table scans for queries for multiple state
groups.
We fix this by manually setting `n_distinct` on the column.

while I'm dealing with INTEGERs and BIGINTs, let's replace room_depth.min_depth
with a BIGINT.

Fixes #9602

this was a typo introduced in #10282. We don't want to end up doing the
`replace_stream_ordering_column` update after anything that comes up in
migration 60/03.
|
| | |
|
| |
|
|
| |
We need to rebuild *all* of the indexes that use the current `stream_ordering`
column.

Fixes #9490
This will break a couple of SyTest that are expecting failures to be added to the response of a federation /send, which obviously doesn't happen now that things are asynchronous.
Two drawbacks:
Currently there is no logic to handle any events left in the staging area after restart, and so they'll only be handled on the next incoming event in that room. That can be fixed separately.
We now only process one event per room at a time. This can be fixed up further down the line.

This adds a simple best effort locking mechanism that works cross workers.

* Move background update names out to a separate class
`EventsBackgroundUpdatesStore` gets inherited and we don't really want to
further pollute the namespace.
* Migrate stream_ordering to a bigint

This implements refresh tokens, as defined by MSC2918
This MSC has been implemented client side in Hydrogen Web: vector-im/hydrogen-web#235
The basics of the MSC works: requesting refresh tokens on login, having the access tokens expire, and using the refresh token to get a new one.

The hope here is that by moving all the schema files into synapse/storage/schema, it gets a bit easier for newcomers to navigate.
It certainly got easier for me to write a helpful README. There's more to do on that front, but I'll follow up with other PRs for that.
