Previously only Twisted's EPollReactor was compatible with the
reactor timing metric, notably not working when asyncio was used.
After this change, the following configurations support the reactor
timing metric:
* poll, epoll, or select reactors
* asyncio reactor with a poll, epoll, select, /dev/poll, or kqueue event loop.
The event persistence code used to handle multiple rooms
at a time, but was simplified to only ever be called with a
single room at a time (different rooms are now handled in
parallel). The code is still generic to multiple rooms causing
a lot of work that is unnecessary (e.g. unnecessary loops, and
partitioning data by room).
This strips out the ability to handle multiple rooms at once, greatly
simplifying the code.
Just to standardize on the normal helpers, it might also have
a slight perf improvement on PostgreSQL which will now use
`ANY (?)` instead of `IN (?, ?, ...)`.
This is mostly useful for federated rooms where some users
would get stuck in the invite or knock state when the room
was purged from their homeserver.
This adds a module API which allows a module to update a user's
presence state/status message. This is useful for controlling presence
from an external system.
To fully control presence from the module the presence.enabled config
parameter gains a new state of "untracked" which disables internal tracking
of presence changes via user actions, etc. Only updates from the module will
be persisted and sent down sync properly).
* Fix bug where a new writer advances their token too quickly
When starting a new writer (for e.g. persisting events), the
`MultiWriterIdGenerator` doesn't have a minimum token for it as there
are no rows matching that new writer in the DB.
This results in the the first stream ID it acquired being announced as
persisted *before* it actually finishes persisting, if another writer
gets and persists a subsequent stream ID. This is due to the logic of
setting the minimum persisted position to the minimum known position of
across all writers, and the new writer starts off not being considered.
* Fix sending out POSITIONs when our token advances without update
Broke in #14820
* For replication HTTP requests, only wait for minimal position
This could happen if the last rows in the account data stream were inserted into `account_data`. After a restart the max account ID would be calculated without looking at the `account_data` table, and so have an old ID.
If using the script remotely, there's no particularly convincing reason
to disable certificate verification, as this makes the connection
interceptible.
If on the other hand, the script is used locally (the most common use
case), you can simply target the HTTP listener and avoid TLS altogether.
This is what the script already attempts to do if passed a homeserver
configuration YAML file.
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.
Synapse was incorrectly implemented with a knock_state_events
property on some APIs (instead of knock_room_state). This was
correct in Synapse 1.70.0, but *both* fields were sent to also be
compatible with Synapse versions expecting the wrong field.
Enough time has passed that only the correct field needs to be
included/handled.
This converts the media servlet URLs in the same way as
(most) of the rest of Synapse. This will give more flexibility
in the versions each endpoint exists under.
This avoids calling cursor_to_dict and then immediately
unpacking the values in the dict for other users. By not
creating the intermediate dictionary we can avoid allocating
the dictionary and strings for the keys, which should generally
be more performant.
Additionally this improves type hints by avoid Dict[str, Any]
dictionaries coming out of the database layer.

Assert that the return type of callables wrapped in @cached
and @cachedList are cachable (aka immutable).
This is because if a worker reaches ~100% CPU then everything starts
lagging and we hit the log line a lot. When at error we invoke sentry
and that has a lot of overhead, which then puts even more pressure on
the worker.
Also add restore of purge/shutdown rooms after a synapse restart.

Refresh tokens were not correctly moved to the rehydrated
device (similar to how the access token is currently handled).
This resulted in invalid refresh tokens after rehydration.
Adds both the List-Unsubscribe (RFC2369) and List-Unsubscribe-Post (RFC8058)
headers to push notification emails, which together should:
* Show an "Unsubscribe" link in the MUA UI when viewing Synapse notification emails.
* Enable "one-click" unsubscribe (the user never leaves their MUA, which automatically
makes a POST request to the specified endpoint).
Using the new `TaskScheduler` meant that we'ed create lots of new
metrics (due to adding task ID to the desc of background process),
resulting in requests for metrics taking an increasing amount of CPU.

Add a (long) timeout to when a "busy" device is considered not online.
This does *not* match MSC3026, but is a reasonable thing for an
implementation to do.
Expands tests for the (unstable) busy presence with multiple devices.
Tracks presence on an individual per-device basis and combine
the per-device state into a per-user state. This should help in
situations where a user has multiple devices with conflicting status
(e.g. one is syncing with unavailable and one is syncing with online).
The tie-breaking is done by priority:
BUSY > ONLINE > UNAVAILABLE > OFFLINE
* Fix rare bug that broke looping calls
We can't interact with the reactor from the main thread via looping
call.
Introduced in v1.90.0 / #15791.
* Newsfile
Refactoring to use both the user ID & the device ID when tracking
the currently syncing users in the presence handler.
This is done both locally and over replication. Note that the device
ID is discarded but will be used in a future change.
Refactoring to pass the device ID (in addition to the user ID) through
the presence handler (specifically the `user_syncing`, `set_state`,
and `bump_presence_active_time` methods and their replication
versions).
Simplify some of the presence code by reducing duplicated code between
worker & non-worker modes.
The main change is to push some of the logic from `user_syncing` into
`set_state`. This is done by passing whether the user is setting the presence
via a `/sync` with a new `is_sync` flag to `set_state`. If this is `true` some
additional logic is performed:
* Don't override `busy` presence.
* Update the `last_user_sync_ts`.
* Never update the status message.
* Properly update retry_last_ts when hitting the maximum retry interval
This was broken in 1.87 when the maximum retry interval got changed from
almost infinite to a week (and made configurable).

If we don't have all the auth events in a room then not all state events will have a chain cover index. Even so, we can still use the chain cover index on the events that do have it, rather than bailing and using the slower functions.
This situation should not arise for newly persisted rooms, as we check we have the full auth chain for each event, but can happen for existing rooms.

For now this maintains compatible with old Synapses by falling back
to using transaction semantics on a per-access token. A future version
of Synapse will drop support for this.
Adds three new configuration variables:
* destination_min_retry_interval is identical to before (10mn).
* destination_retry_multiplier is now 2 instead of 5, the maximum value will
be reached slower.
* destination_max_retry_interval is one day instead of (essentially) infinity.
Capping this will cause destinations to continue to be retried sometimes instead
of being lost forever. The previous value was 2 ^ 62 milliseconds.
The location of the redacts field changes in room version 11. Ensure
it is copied to the *new* location for *old* room versions for
forwards-compatibility with clients.
Note that copying it to the *old* location for the *new* room version
was previously handled.
The un_partial_stated_event_stream_sequence and
application_services_txn_id_seq were never properly configured
in the portdb script, resulting in an error on start-up.

Allow configuring the set of workers to proxy outbound federation traffic through (`outbound_federation_restricted_to`).
This is useful when you have a worker setup with `federation_sender` instances responsible for sending outbound federation requests and want to make sure *all* outbound federation traffic goes through those instances. Before this change, the generic workers would still contact federation themselves for things like profile lookups, backfill, etc. This PR allows you to set more strict access controls/firewall for all workers and only allow the `federation_sender`'s to contact the outside world.
**Before:**
```
Error retrieving alias
```
**After:**
```

```
*Spawning from creating the [manual testing strategy for the outbound federation proxy](https://github.com/matrix-org/synapse/pull/15773).*
Unix socket support for `federation` and `client` Listeners has existed now for a little while(since [1.81.0](https://github.com/matrix-org/synapse/pull/15353)), but there was one last hold out before it could be complete: HTTP Replication communication. This should finish it up. The Listeners would have always worked, but would have had no way to be talked to/at.

Old device entries for the same user were being removed in individual
SQL commands, making the batch take way longer than necessary.
This combines the commands into a single one with a IN/ANY clause.
Example of log entry before the change, regularly observed with
"log_min_duration_statement = 10000" in PostgreSQL's config:
LOG: duration: 42538.282 ms statement:
DELETE FROM device_lists_stream
WHERE user_id = '@someone' AND device_id = 'someid1'
AND stream_id < 123456789
;
DELETE FROM device_lists_stream
WHERE user_id = '@someone' AND device_id = 'someid2'
AND stream_id < 123456789
;
[repeated for each device ID of that user, potentially a lot...]
With the patch applied on my instance for the past couple of days, I
no longer notice overly long statements of that particular kind.

We now only block the client to backfill when we see a large gap in the events (more than 2 events missing in a row according to `depth`), more than 3 single-event holes, or not enough messages to fill the response. Otherwise, we return the messages directly to the client and backfill in the background for eventual consistency sake.
Fix https://github.com/matrix-org/synapse/issues/15696
* Check required power levels earlier in createRoom handler.
- If a server was configured to reject the creation of rooms with E2EE
enabled (by specifying an unattainably high power level for
"m.room.encryption" in default_power_level_content_override), the 403
error was not being triggered until after the room was created and
before the "m.room.power_levels" was sent. This allowed a user to
access the partially-configured room and complete the setup of E2EE
and power levels manually.
- This change causes the power level overrides to be checked earlier and
the request to be rejected before the user gains access to the room.
- A new `_validate_room_config` method is added to contain checks that
should be run before a room is created.
- The new test case confirms that a user request is rejected by the new
validation method.

This is useful because when see that a relevant event is an `outlier` or `soft-failed`, then that's a good unexpected indicator explaining why it's not showing up. `filter_events_for_client` is used in `/sync`, `/messages`, `/context` which are all common end-to-end assertion touch points (also notifications, relations).
Implements stable support for MSC3882; this involves updating Synapse's support to
match the MSC / the spec says.
Continue to support the unstable version to allow clients to transition.
The stubs have some issues so this has some generous cast
and ignores in it, but it is better than not having stubs.
Note that confusing that Element is a function which creates
_Element instances (and similarly for Comment).
