Enforce that we use index scans (rather than seq scans), which we also do for state queries. The reason to enforce this is that we can't correctly get PostgreSQL to understand the distribution of `stream_ordering` depends on `highlight`, and so it always defaults (on matrix.org) to sequential scans.
Updates the database schema to require a thread_id (by adding a
constraint that the column is non-null) for event_push_actions,
event_push_actions_staging, and event_push_actions_summary.
For PostgreSQL we add the constraint as NOT VALID, then
VALIDATE the constraint a background job to avoid locking
the table during an upgrade.
For SQLite we simply rebuild the table & copy the data.
Pushers tend to make many connections to the same HTTP host
(e.g. a new event comes in, causes events to be pushed, and then
the homeserver connects to the same host many times). Due to this
the per-host HTTP connection pool size was increased, but this does
not make sense for other SimpleHttpClients.
Add a parameter for the connection pool and override it for pushers
(making a separate SimpleHttpClient for pushers with the increased
configuration).
This returns the HTTP connection pool settings to the default Twisted
ones for non-pusher HTTP clients.
Adds an optional keyword argument to the /relations API which
will recurse a limited number of event relationships.
This will cause the API to return not just the events related to the
parent event, but also events related to those related to the parent
event, etc.
This is disabled by default behind an experimental configuration
flag and is currently implemented using prefixed parameters.
MSC3983 provides a way to request multiple OTKs at once from appservices,
this extends this concept to the Client-Server API.
Note that this will likely be spit out into a separate MSC, but is currently part of
MSC3983.

It can be useful to always return the fallback key when attempting to
claim keys. This adds an unstable endpoint for `/keys/claim` which
always returns fallback keys in addition to one-time-keys.
The fallback key(s) are not marked as "used" unless there are no
corresponding OTKs.
This is currently defined in MSC3983 (although likely to be split out
to a separate MSC). The endpoint shape may change or be requested
differently (i.e. a keyword parameter on the current endpoint), but the
core logic should be reasonable.
Before this change:
* `PerspectivesKeyFetcher` and `ServerKeyFetcher` write to `server_keys_json`.
* `PerspectivesKeyFetcher` also writes to `server_signature_keys`.
* `StoreKeyFetcher` reads from `server_signature_keys`.
After this change:
* `PerspectivesKeyFetcher` and `ServerKeyFetcher` write to `server_keys_json`.
* `PerspectivesKeyFetcher` also writes to `server_signature_keys`.
* `StoreKeyFetcher` reads from `server_keys_json`.
This results in `StoreKeyFetcher` now using the results from `ServerKeyFetcher`
in addition to those from `PerspectivesKeyFetcher`, i.e. keys which are directly
fetched from a server will now be pulled from the database instead of refetched.
An additional minor change is included to avoid creating a `PerspectivesKeyFetcher`
(and checking it) if no `trusted_key_servers` are configured.
The overall impact of this should be better usage of cached results:
* If a server has no trusted key servers configured then it should reduce how often keys
are fetched.
* if a server's trusted key server does not have a requested server's keys cached then it
should reduce how often keys are directly fetched.
These two lines:
```
config_obj = HomeServerConfig()
config_obj.parse_config_dict(config, "", "")
```
are called many times with the exact same value for `config`.
As the test suite is CPU-bound and non-negligeably time is spent in
`parse_config_dict`, this saves ~5% on the overall runtime of the Trial
test suite (tested with both `-j2` and `-j12` on a 12t CPU).
This is sadly rather limited, as the cache cannot be shared between
processes (it contains at least jinja2.Template and RLock objects which
aren't pickleable), and Trial tends to run close tests in different
processes.
* Switch InstanceLocationConfig to a pydantic BaseModel, apply Strict* types and add a few helper methods(that will make more sense in follow up work).

* More precise type for LoggingTransaction.execute
* Add an annotation for stream_ordering_month_ago
This would have spotted the error that was fixed in "Add comma missing from #15382. (#15429)"
c.f. #15264
The two changes are:
1. Add indexes so that the select / deletes don't do sequential scans
2. Don't repeatedly call `SELECT count(*)` each iteration, as that's slow
The registration fallback is broken and unspecced. This removes it
since there is no plan to spec it.
Note that this does not modify the login fallback code.
* Change `store_server_verify_keys` to take a `Mapping[(str, str), FKR]`
This is because we already can't handle duplicate keys — leads to cardinality violation

This change fixes a rare bug where initial /syncs would fail with a
`KeyError` under the following circumstances:
1. A user fast joins a remote room.
2. The user is kicked from the room before the room's full state has
been synced.
3. A second local user fast joins the room.
4. Events are backfilled into the room with a higher topological
ordering than the original user's leave. They are assigned a
negative stream ordering. It's not clear how backfill happened here,
since it is expected to be equivalent to syncing the full state.
5. The second local user leaves the room before the room's full state
has been synced. The homeserver does not complete the sync.
6. The original user performs an initial /sync with lazy_load_members
enabled.
* Because they were kicked from the room, the room is included in
the /sync response even though the include_leave option is not
specified.
* To populate the room's timeline, `_load_filtered_recents` /
`get_recent_events_for_room` fetches events with a lower stream
ordering than the leave event and picks the ones with the highest
topological orderings (which are most recent). This captures the
backfilled events after the leave, since they have a negative
stream ordering. These events are filtered out of the timeline,
since the user was not in the room at the time and cannot view
them. The sync code ends up with an empty timeline for the room
that notably does not include the user's leave event.
This seems buggy, but at least we don't disclose events the user
isn't allowed to see.
* Normally, `compute_state_delta` would fetch the state at the
start and end of the room's timeline to generate the sync
response. Since the timeline is empty, it fetches the state at
`min(now, last event in the room)`, which corresponds with the
second user's leave. The state during the entirety of the second
user's membership does not include the membership for the first
user because of partial state.
This part is also questionable, since we are fetching state from
outside the bounds of the user's membership.
* `compute_state_delta` then tries and fails to find the user's
membership in the auth events of timeline events. Because there
is no timeline event whose auth events are expected to contain
the user's membership, a `KeyError` is raised.
Also contains a drive-by fix for a separate unlikely race condition.

Clean-up from adding the thread_id column, which was initially
null but backfilled with values. It is desirable to require it to now
be non-null.
In addition to altering this column to be non-null, we clean up
obsolete background jobs, indexes, and just-in-time updating
code.
If enabled, for users which are exclusively owned by an application
service then the appservice will be queried for devices in addition
to any information stored in the Synapse database.
Previously, we would spin in a tight loop until
`update_state_for_partial_state_event` stopped raising
`FederationPullAttemptBackoffError`s. Replace the spinloop with a wait
until the backoff period has expired.

This should help reduce the number of devices e.g. simple bots the repeatedly login rack up.
We only delete non-e2e devices as they should be safe to delete, whereas if we delete e2e devices for a user we may accidentally break their ability to receive e2e keys for a message.
* Fix joining rooms you have been unbanned from
Since forever synapse did not allow you to join a room after you have
been unbanned from it over federation. This was not actually because of
the unban event not federating. Synapse simply used outdated state to
validate the join transition. This skips the validation if we are not in
the room and for that reason won't have the current room state.

Experimental support for MSC3983 is behind a configuration flag.
If enabled, for users which are exclusively owned by an application
service then the appservice will be queried for one-time keys *if*
there are none uploaded to Synapse.
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.
Invalid mentions data received over the Client-Server API should
be rejected with a 400 error. This will hopefully stop clients from
sending invalid data, although does not help with data received
over federation.
* Add `event_stream_ordering` column to membership state tables
Specifically this adds the column to `current_state_events`,
`local_current_membership` and `room_memberships`. Each of these tables
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.
* Make denormalised `event_stream_ordering` columns foreign keys
* 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
* Bump schema version to 75

* Have replication clients remove _INT_STREAM_POS
Suppose worker A makes an internal http request from worker B. B may
make changes that A later learns about over replication. We want A's
request to block until it has seen those changes—mainly to ensure A's
caches are invalidated promptly. This helps provide read-after-write
consistency, eliminating entire categories of races and test flakes.
To implement this, B includes a top-level field `_INT_STREAM_POS` in its
response JSON. Roughly speaking, the field's value tells A what to wait
for. But we weren't removing that internal field before A's request
completed!
Introduced in https://github.com/matrix-org/synapse/pull/14820.
Fixes#15308.
* Changelog
When a room is deleted in Synapse we remove the event forward
extremities in the room, so if (say a bot) tries to send a message into
the room we error out due to not being able to calculate prev events for
the new event *before* we check if the sender is in the room.

It is not necessary to reach out to the database to check some
parameters if the auto-join rooms are not configured, or (in some cases)
if auto-create rooms is not configured.
When pushing events in partial state rooms down incremental /sync, we
try to find the `m.room.member` state event for their senders by digging
through their auth events, so that we can present the membership to the
client. Events usually have a membership event in their auth events,
with the exception of the `m.room.create` event and a user's first join
into the room.
When implementing #13477, we took the case of a user's first join into
account, but forgot to handle the `m.room.create` case. This change
fixes that.

This removes the experimental configuration option and
always escapes the push rule condition keys.
Also escapes any (experimental) push rule condition keys
in the base rules which contain dot in a field name.
Enables MSC3925 support by default, which:
* Includes the full edit event in the bundled aggregations of an
edited event.
* Stops modifying the original event's content to return the new
content from the edit event.
This is a backwards-incompatible change that is considered to be
"correct" by the spec.
AbstractStreamIdTracker (now) has only a single sub-class: AbstractStreamIdGenerator,
combine them to simplify some code and remove any direct references to
AbstractStreamIdTracker.
This replaces the specific `is_user_mention` push rule condition
used in MSC3952 with the generic `exact_event_property_contains`
push rule condition from MSC3966.
It turns out that no clients rely on server-side aggregation of `m.annotation`
relationships: it's just not very useful as currently implemented.
It's also non-trivial to calculate.
I want to remove it from MSC2677, so to keep the implementation in line, let's
remove it here.
Internally the push rules module uses a `pattern_type` property for `event_match`
conditions (and `related_event_match`) to mark the condition as matching the
current user's Matrix ID or localpart.
This is leaky to the Client-Server API where a user can successfully set a condition
which provides `pattern_type` instead of `pattern` (note that there's no benefit to
doing this -- the user can just use their own Matrix ID or localpart instead). When
serializing back to the client the `pattern_type` property is converted into a proper
`pattern`.
The following changes are made to avoid this:
* Separate the `KnownCondition::EventMatch` enum value into `EventMatch`
and `EventMatchType`, each with their own expected properties. (Note that a
similar change is made for `RelatedEventMatch`.)
* Make it such that the `pattern_type` variants serialize to the same condition kind,
but cannot be deserialized (since they're only provided by base rules).
* As a final tweak, convert `user_id` vs. `user_localpart` values into an enum.
* Add documentation for caching in a module

Previously if an autodiscovered oEmbed request failed (e.g. the
oEmbed endpoint is down or does not exist) then the entire URL
preview would fail. Instead we now return everything we can, even
if this additional request fails.
Ideally we would replace this with parsing of the Accept header
or something else, but for now just make Synapse spec compliant
by ignoring the unspecced parameter.
It does not seem that this is ever sent by a client, and even if it is
there's a reasonable fallback.
