When a room has the partial state flag, we may not have an accurate
`m.room.member` event for event senders in the room's current state, and
so cannot perform soft fail checks correctly. Skip the soft fail check
entirely in this case.
As an alternative, we could block until we have full state, but that
would prevent us from receiving incoming events over federation, which
is undesirable.

## New error code and status
### Before
Previously, we returned a `404` for `/thumbnail` which isn't even in the spec.
```json
{
"errcode": "M_NOT_FOUND",
"error": "Not found [b'hs1', b'tefQeZhmVxoiBfuFQUKRzJxc']"
}
```
### After
What does the spec say?
> 400: The request does not make sense to the server, or the server cannot thumbnail the content. For example, the client requested non-integer dimensions or asked for negatively-sized images.
>
> *-- https://spec.matrix.org/v1.1/client-server-api/#get_matrixmediav3thumbnailservernamemediaid*
Now with this PR, we respond with a `400` when we don't have thumbnails to serve and we explain why we might not have any thumbnails.
```json
{
"errcode": "M_UNKNOWN",
"error": "Cannot find any thumbnails for the requested media ([b'example.com', b'12345']). This might mean the media is not a supported_media_format=(image/jpeg, image/jpg, image/webp, image/gif, image/png) or that thumbnailing failed for some other reason. (Dynamic thumbnails are disabled on this server.)",
}
```

These columns were added back in Synapse 1.52, and have been populated for new
events since then. It's now (beyond) time to back-populate them for existing
events.
There are two fixes here:
1. A long-standing bug where we incorrectly calculated `delta_ids`; and
2. A bug introduced in #13267 where we got current state incorrect.
When building the docker images for complement testing, copy a preinstalled
complement over from a base image, rather than apt installing it. This avoids

* Replace `get_new_events_for_appservice` with `get_all_new_events_stream`
The functions were near identical and this brings the AS worker closer
to the way federation senders work which can allow for multiple workers
to handle AS traffic.
* Pull received TS alongside events when processing the stream
This avoids an extra query -per event- when both federation sender
and appservice pusher process events.
There is a corner in `_check_event_auth` (long known as "the weird corner") where, if we get an event with auth_events which don't match those we were expecting, we attempt to resolve the diffence between our state and the remote's with a state resolution.
This isn't specced, and there's general agreement we shouldn't be doing it.
However, it turns out that the faster-joins code was relying on it, so we need to introduce something similar (but rather simpler) for that.

This happens when you have some messages imported before the room is created.
Then use MSC3030 to look backwards before the room creation from a remote
federated server. The server won't find anything locally, but will ask over
federation which will have the remote event. The previous logic would
choke on not having the local event assigned.

Method `_get_state_map_for_room` seems to break in presence of some ill-formed events in the database. Reimplementing this method to use `get_current_state`, which is more robust to such events.
This happened if we encountered a stream ordering in `event_push_actions` that had more rows than the batch size of the delete, as If we don't delete any rows in an iteration then the next time round we get the exact same stream ordering and get stuck.
Whenever we want to persist an event, we first compute an event context,
which includes the state at the event and a flag indicating whether the
state is partial. After a lot of processing, we finally try to store the
event in the database, which can fail for partial state events when the
containing room has been un-partial stated in the meantime.
We detect the race as a foreign key constraint failure in the data store
layer and turn it into a special `PartialStateConflictError` exception,
which makes its way up to the method in which we computed the event
context.
To make things difficult, the exception needs to cross a replication
request: `/fed_send_events` for events coming over federation and
`/send_event` for events from clients. We transport the
`PartialStateConflictError` as a `409 Conflict` over replication and
turn `409`s back into `PartialStateConflictError`s on the worker making
the request.
All client events go through
`EventCreationHandler.handle_new_client_event`, which is called in
*a lot* of places. Instead of trying to update all the code which
creates client events, we turn the `PartialStateConflictError` into a
`429 Too Many Requests` in
`EventCreationHandler.handle_new_client_event` and hope that clients
take it as a hint to retry their request.
On the federation event side, there are 7 places which compute event
contexts. 4 of them use outlier event contexts:
`FederationEventHandler._auth_and_persist_outliers_inner`,
`FederationHandler.do_knock`, `FederationHandler.on_invite_request` and
`FederationHandler.do_remotely_reject_invite`. These events won't have
the partial state flag, so we do not need to do anything for then.
The remaining 3 paths which create events are
`FederationEventHandler.process_remote_join`,
`FederationEventHandler.on_send_membership_event` and
`FederationEventHandler._process_received_pdu`.
We can't experience the race in `process_remote_join`, unless we're
handling an additional join into a partial state room, which currently
blocks, so we make no attempt to handle it correctly.
`on_send_membership_event` is only called by
`FederationServer._on_send_membership_event`, so we catch the
`PartialStateConflictError` there and retry just once.
`_process_received_pdu` is called by `on_receive_pdu` for incoming
events and `_process_pulled_event` for backfill. The latter should never
try to persist partial state events, so we ignore it. We catch the
`PartialStateConflictError` in `on_receive_pdu` and retry just once.
Refering to the graph of code paths in
https://github.com/matrix-org/synapse/issues/12988#issuecomment-1156857648

* Add auth events to events used in tests

* Rename check_auth_rules_for_event
Now it only checks the state-dependent auth rules, it needs a better name.
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.

This simplifies the access token verification logic by removing the `rights`
parameter which was only ever used for the unsubscribe link in email
notifications. The latter has been moved under the `/_synapse` namespace,
since it is not a standard API.
This also makes the email verification link more secure, by embedding the
app_id and pushkey in the macaroon and verifying it. This prevents the user
from tampering the query parameters of that unsubscribe link.
Macaroon generation is refactored:
- Centralised all macaroon generation and verification logic to the
`MacaroonGenerator`
- Moved to `synapse.utils`
- Changed the constructor to require only a `Clock`, hostname, and a secret key
(instead of a full `Homeserver`).
- Added tests for all methods.
Instead, use the `room_version` property of the event we're checking.
The `room_version` was originally added as a parameter somewhere around #4482,
but really it's been redundant since #6875 added a `room_version` field to `EventBase`.
Instead, use the `room_version` property of the event we're validating.
The `room_version` was originally added as a parameter somewhere around #4482,
but really it's been redundant since #6875 added a `room_version` field to `EventBase`.
In practice, when we run the auth rules, all of the events have the right room
version. Let's stop building Room V1 events for these tests and use the right
version.
The `room_id` field was removed from MSC2946 before
it was accepted. It was initially kept for backwards compatibility
and should be removed now that the stable form of the API
is used.
This change only stops Synapse from validating that it is returned,
a future PR will remove returning it as part of the response.

Currently, we try to pull the event corresponding to a sync token from the database. However, when
we fetch redaction events, we check the target of that redaction (because we aren't allowed to send
redactions to clients without validating them). So, if the sync token points to a redaction of an event
that we don't have, we have a problem.
It turns out we don't really need that event, and can just work with its ID and metadata, which
sidesteps the whole problem.
* Raise a dedicated `InvalidEventSignatureError` from `_check_sigs_on_pdu`
* Downgrade logging about redactions to DEBUG
this can be very spammy during a room join, and it's not very useful.
* Raise `InvalidEventSignatureError` from `_check_sigs_and_hash`
... and, more importantly, move the logging out to the callers.

Synapse 1.60.0rc2 (2022-05-27)
==============================
This release of Synapse adds a unique index to the `state_group_edges` table, in
order to prevent accidentally introducing duplicate information (for example,
because a database backup was restored multiple times). If your Synapse database
already has duplicate rows in this table, this could fail with an error and
require manual remediation.
Additionally, the signature of the `check_event_for_spam` module callback has changed.
The previous signature has been deprecated and remains working for now. Module authors
should update their modules to use the new signature where possible.
See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1600)
for more details.
Features
--------
- Add an option allowing users to use their password to reauthenticate for privileged actions even though password login is disabled. ([\#12883](https://github.com/matrix-org/synapse/issues/12883))
Bugfixes
--------
- Explicitly close `ijson` coroutines once we are done with them, instead of leaving the garbage collector to close them. ([\#12875](https://github.com/matrix-org/synapse/issues/12875))
Internal Changes
----------------
- Improve URL previews by not including the content of media tags in the generated description. ([\#12887](https://github.com/matrix-org/synapse/issues/12887))
Hopefully this means that exceptions raised due to truncated JSON
get a sensible logging context and stack.

* Refactor HTTP response size limits
Rather than passing a separate `max_response_size` down the stack, make it an

* Allow bigger responses on `federation/v1/state`
`/state` can return huge responses, so we need to handle that.
Makes it so that groups/communities no longer exist from a user-POV. E.g. we remove:
* All API endpoints (including Client-Server, Server-Server, and admin).
* Documented configuration options (and the experimental flag, which is now unused).
* Special handling during room upgrades.
* The `groups` section of the `/sync` response.
By always returning all requested values from the function
wrapped by cachedList. Otherwise implicit None values get
added into the cache, which are unexpected.
Implements the following behind an experimental configuration flag:
* A new push rule kind for mutually related events.
* A new default push rule (`.m.rule.thread_reply`) under an unstable prefix.
This is missing part of MSC3772:
* The `.m.rule.thread_reply_to_me` push rule, this depends on MSC3664 / #11804.
The main differences are:
- values with delimiters (such as colons) should be quoted, so always
quote the origin, since it could contain a colon followed by a port
number
- should allow more than one space after "X-Matrix"
- quoted values with backslash-escaped characters should be unescaped
- names should be case insensitive
A minor optimization to avoid unnecessary copying/building
identical dictionaries when filtering private read receipts.
Also clarifies comments and cleans-up some tests.

* Validation of the Client-Server API.
* Fetching bundled aggregations.

Each of these separately implement the logic and each made slightly
different assumptions about what was valid. Some had minor / potential

Refactor how the `EventContext` class works, with the intention of reducing the amount of state we fetch from the DB during event processing.
The idea here is to get rid of the cached `current_state_ids` and `prev_state_ids` that live in the `EventContext`, and instead defer straight to the database (and its caching).
One change that may have a noticeable effect is that we now no longer prefill the `get_current_state_ids` cache on a state change. However, that query is relatively light, since its just a case of reading a table from the DB (unlike fetching state at an event which is more heavyweight). For deployments with workers this cache isn't even used.
Part of #12684
All async request processing goes through `_AsyncResource`, so this is
the only place where a `Deferred` needs to be captured for cancellation.
Unfortunately, the same isn't true for determining whether a request
can be cancelled. Each of `RestServlet`, `BaseFederationServlet`,
`DirectServe{Html,Json}Resource` and `ReplicationEndpoint` have
different wrappers around the method doing the request handling and they
all need to be handled separately.

* `uk.half-shot.msc2778.login.application_service`, which was
stabilized as part of the Matrix spec v1.2 release.
The `latest_event` field of the bundled aggregations for `m.thread` relations
did not include bundled aggregations itself. This resulted in clients needing to
immediately request the event from the server (and thus making it useless that
the latest event itself was serialized instead of just including an event ID).
I've seen a few errors which can only plausibly be explained by the calculated
event id for an event being different from the ID of the event in the
database. It should be cheap to check this, so let's do so and raise an
exception.
Check we're on the right branch before tagging, and on the right tag before uploading
* Abort if we're on the wrong branch
* Check we have the right tag checked out

This works by taking a row level lock on the `rooms` table at the start of both transactions, ensuring that they don't run at the same time. In the event persistence transaction we also check that there is an entry still in the `rooms` table.
I can't figure out how to do this in SQLite. I was just going to lock the table, but it seems that we don't support that in SQLite either, so I'm *really* confused as to how we maintain integrity in SQLite when using `lock_table`....
This was originally added when we first added a `MemoryHandler` to the default
log config back in https://github.com/matrix-org/synapse/pull/8040, to ensure
that we didn't explode with an infinite loop if there was an error formatting
the logs.
Since then, we made additional improvements to logging which make this
workaround redundant. In particular:
* we no longer attempt to log un-UTF8-decodable byte sequences, which were the
most likely cause of an error in the first place.
* https://github.com/matrix-org/synapse/pull/8268 ensures that in the unlikely
case that there *is* an error, it won't cause an infinite loop.

arbitrary awaitables.

Over time we've begun to use newer versions of mypy, typeshed, stub
packages---and of course we've improved our own annotations. This makes
some type ignore comments no longer necessary. I have removed them.
There was one exception: a module that imports `select.epoll`. The
ignore is redundant on Linux, but I've kept it ignored for those of us
who work on the source tree using not-Linux. (#11771)
I'm more interested in the config line which enforces this. I want
unused ignores to be reported, because I think it's useful feedback when
annotating to know when you've fixed a problem you had to previously
ignore.
* Installing extras before typechecking
Lacking an easy way to install all extras generically, let's bite the bullet and
make install the hand-maintained `all` extra before typechecking.
Now that https://github.com/matrix-org/backend-meta/pull/6 is merged to
the release/v1 branch.
Synapse 1.58.0rc2 (2022-04-26)
==============================
This release candidate fixes bugs related to Synapse 1.58.0rc1's logic for handling device list updates.
Bugfixes
--------
- Fix a bug introduced in Synapse 1.58.0rc1 where the main process could consume excessive amounts of CPU and memory while handling sentry logging failures. ([\#12554](https://github.com/matrix-org/synapse/issues/12554))
- Fix a bug introduced in Synapse 1.58.0rc1 where opentracing contexts were not correctly sent to whitelisted remote servers with device lists updates. ([\#12555](https://github.com/matrix-org/synapse/issues/12555))
Internal Changes
----------------
- Reduce unnecessary work when handling remote device list updates. ([\#12557](https://github.com/matrix-org/synapse/issues/12557))
Try to avoid an OOM by checking fewer extremities.
Generally this is a big rewrite of _maybe_backfill, to try and fix some of the TODOs and other problems in it. It's best reviewed commit-by-commit.
Multiple calls to `EventsWorkerStore._get_events_from_cache_or_db` can
reuse the same database fetch, which is initiated by the first call.
Ensure that cancelling the first call doesn't cancel the other calls
sharing the same database fetch.

This will mainly be useful when dealing with module callbacks, which are
all typed as returning `Awaitable`s instead of coroutines or
`Deferred`s.
Signed-off-by: Sean Quah <seanq@element.io>
When we join a room via the faster-joins mechanism, we end up with "partial
state" at some points on the event DAG. Many parts of the codebase need to
wait for the full state to load. So, we implement a mechanism to keep track of
which events have partial state, and wait for them to be fully-populated.
MSC2314 has now been closed, so we're backing out its implementation, which
originally happened in #6176.
Unfortunately it's not a direct revert, as that PR mixed in a bunch of
unrelated changes to tests etc.

When we run a worker-mode synapse under docker, everything gets logged to stdout. Currently, output from the workers is tacked with a worker name, for example:
```
2022-04-13 15:27:56,810 - worker:frontend_proxy1 - synapse.util.caches.lrucache - 154 - INFO - LruCache._expire_old_entries-0 - Dropped 0 items from caches
```
- note `worker:frontend_proxy1`. No such tag is applied to log lines from the master, which makes somewhat confusing reading.
To fix this, we generate a dedicated log config file for the master in the same way that we do for the workers, and use that.
In trying to use the MSC3026 busy presence status, the user's status
would be set back to 'online' next time they synced. This change makes
it so that syncing does not affect a user's presence status if it
is currently set to 'busy': it must be removed through the presence
API.
The MSC defers to implementations on the behaviour of busy presence,
so this ought to remain compatible with the MSC.
* Run "main" trial tests under poetry
Olddeps and twisted trunk tests are handled in separate PRs.
The PyPy config is a best-effort only; it's completely untested.
Pulled out from #12337.
* Changelog
This was missed when initially stabilising room version 8 and was
left in as a compatibility shim. Most homeservers have upgraded
to a version which expects the proper field name, and the failure
mode is reasonable (a user on an older server may have to attempt
joining the room twice with an obscure error message the first time).
We work through all the events with partial state, updating the state at each
of them. Once it's done, we recalculate the state for the whole room, and then
mark the room as having complete state.
* Add some type hints to datastore
* newsfile
* change `Collection` to `List`
* refactor return type of `select_users_txn`
* correct type hint in `stream.py`
* Remove `Optional` in `select_users_txn`
* remove not needed return type in `__init__`
* Revert change in `get_stream_id_for_event_txn`
* Remove import from `Literal`
* Specify `tls` extra for Twisted dependency.
It was already pulled in for us by `treq`, but we should be explicit
that we do use the `tls` functionality of Twisted directly.
* Mark `idna` as dev-dependency
This doesn't actually change anything, as `Twisted[tls]` will put it in
as a main dependency anyway.
The requirements file generated by `poetry export` isn't correctly processed by `pip install -r requirements.txt`. It contains twisted and treq, both pinned to 22.2.0.
When `pip` installs treq, it notices that `Twisted[tls]` is required. It then tries to acquire the latest twisted release, only to fail (because this hash isn't listed in the requirements file).From e.g. https://github.com/matrix-org/synapse/runs/5977154990?check_suite_focus=true
> ```
> #15 9.204 Collecting Twisted[tls]>=18.7.0
> #15 9.205 ERROR: In --require-hashes mode, all requirements must have their versions pinned with ==. These do not:

> #15 ERROR: executor failed running [/bin/sh -c pip install --prefix="/install" --no-warn-script-location -r /synapse/requirements.txt]: exit code: 1
> ```
The underlying pip issue is https://github.com/pypa/pip/issues/9644. A comment notes that one can avoid this behaviour with by `pip install`ing with the `--no-deps` flag. Let us do so.
(At first glance, the problem looks like https://github.com/python-poetry/poetry/issues/5311, but that was a bug in `poetry install`; this is `poetry export`, whose behaviour is fine AFAICS).
Consider the requester's ignored users when calculating the
bundled aggregations.
See #12285 / 4df10d3214
for corresponding changes for the `/relations` endpoint.
Of note:
* No untyped defs in `register_new_matrix_user`
This one might be contraversial. `request_registration` has three
dependency-injection arguments used for testing. I'm removing the
injection of the `requests` module and using `unitest.mock.patch` in the
test cases instead.
Doing `reveal_type(requests)` and `reveal_type(requests.get)` before the
change:
```

synapse/_scripts/register_new_matrix_user.py:46: note: Revealed type is "Any"
```
And after:

```
* Drive-by comment in `synapse.storage.types`
* No untyped defs in `synapse_port_db`
This was by far the most painful. I'm happy to break this up into
smaller pieces for review if it's not managable as-is.
Fixesmatrix-org/complement#330 (or it will, once we remove the old files).
It's not quite a lift-and-shift: I've also taken the opportunity to get rid of the custom CA that we used to use to sign the TLS certs, which has been superceded by the CA exposed by Complement.
* Pull out query param types to `synapse.http.types`
* Use QueryParams everywhere
* Simplify `encode_query_args`
* Add annotation which would have caught #12410
Principally, `prometheus_client.REGISTRY.register` now requires its argument to
extend `prometheus_client.Collector`.
Additionally, `Gauge.set` is now annotated so that passing `Optional[int]`
causes an error.
Just after a task acquires a contended `Linearizer` lock, it sleeps.

`StreamToken.from_string` and `RoomStreamToken.parse` are both async
methods that could be cancelled. These methods must not replace
`CancelledError`s with `SynapseError`s.

Refactor and convert `Linearizer` to async. This makes a `Linearizer`
cancellation bug easier to fix.
Also refactor to use an async context manager, which eliminates an
unlikely footgun where code that doesn't immediately use the context
manager could forget to release the lock.

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.
There are a bunch of places we call get_success on an immediate value, which is unnecessary. Let's rip them out, and remove the redundant functionality in get_success and friends.
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.
It seems like calling `_get_state_group_for_events` for an event where the
state is unknown is an error. Accordingly, let's raise an exception rather than
silently returning an empty result.
If we're missing most of the events in the room state, then we may as well call the /state endpoint, instead of individually requesting each and every event.
The intention here is to avoid doing state lookups for outliers in
`/_matrix/federation/v1/event`. Unfortunately that's expanded into something of
a rewrite of `filter_events_for_server`, which ended up trying to do that
operation in a couple of places.
The PaginationChunk class attempted to bundle some properties
together, but really just caused callers to jump through hoops and
hid implementation details.
This endpoint was removed from MSC2675 before it was approved.
It is currently unspecified (even in any MSCs) and therefore subject to
removal. It is not implemented by any known clients.
This also changes the bundled aggregation format for `m.annotation`,
which previously included pagination tokens for the `/aggregations`
endpoint, which are no longer useful.
Document the behaviour of `LoggingTransaction.call_after` and
`LoggingTransaction.call_on_exception` when transactions are retried.

Follow-up to https://github.com/matrix-org/synapse/pull/12083
Since we are now using the new `state_event_ids` parameter to do all of the heavy lifting.
We can remove any spots where we plumbed `auth_event_ids` just for MSC2716 things in
https://github.com/matrix-org/synapse/pull/9247/files.
Removing `auth_event_ids` from following functions:
- `create_and_send_nonmember_event`
- `_local_membership_update`
- `update_membership`
- `update_membership_locked`
When we are processing a `/backfill` request from a remote server, exclude any
outliers from consideration early on. We can't return outliers anyway (since we
don't know the state at the outlier), and filtering them out earlier means that
we won't attempt to calulate the state for them.
This should speed up push rule calculations for rooms with large numbers of local users when the main push rule cache fails.

* Make it possible to enable compression for the metrics HTTP resource
This can provide significant bandwidth savings pulling metrics from
synapse instances.
* Add changelog file.
* Fix type hint
We fetch the thread summary in two phases:
1. The summary that is shared by all users (count of messages and latest event).
2. Whether the requesting user has participated in the thread.
There's no use in attempting step 2 for events which did not return a summary
from step 1.

An error occured if a filter was supplied with `event_fields` which did not include
`unsigned`.
In that case, bundled aggregations are still added as the spec states it is allowed
for servers to add additional fields.
To handle cancellation, we ensure that `after_callback`s and
`exception_callback`s are always run, since the transaction will
complete on another thread regardless of cancellation.
We also wait until everything is done before releasing the
`CancelledError`, so that logging contexts won't get used after they
have been finished.

* Moves the relation pagination tests to a separate class.
* Move the assertion of the response code into the `_send_relation` helper.

`delay_cancellation` behaves like `stop_cancellation`, except it
delays `CancelledError`s until the original `Deferred` resolves.
This is handy for unifying cleanup paths and ensuring that uncancelled

The unstable identifiers are still supported if the experimental configuration
flag is enabled. The unstable identifiers will be removed in a future release.
This is allowed per MSC2675, although the original implementation did
not allow for it and would return an empty chunk / not bundle aggregations.
The main thing to improve is that the various caches get cleared properly
when an event is redacted, and that edits must not leak if the original
event is redacted (as that would presumably leak something similar to
the original event content).
Since the object it returns is a ReplicationCommandHandler.
This is clean-up from adding support to Redis where the command handler
was added as an additional layer of abstraction from the TCP protocol.
* `@cached` can now take an `uncached_args` which is an iterable of names to not use in the cache key.
* Requires `@cached`, @cachedList` and `@lru_cache` to use keyword arguments for clarity.
* Asserts that keyword-only arguments in cached functions are not accepted. (I tested this briefly and I don't believe this works properly.)
This allows for the target process to be down for around a minute
which provides time for restarts during synapse upgrades/config updates.

* Rewrites the demo documentation to be clearer, accurate, and moves it to our documentation tree.
* Improvements to the demo scripts:
* `clean.sh` now runs `stop.sh` first to avoid zombie processes.
* Uses more modern Synapse configuration (and removes some obsolete configuration).
* Consistently use the HTTP ports for server name, etc.
* Remove the `demo/etc` directory and place everything into the `demo/808x` directories.
This field is only to be used in the Server-Server API, and not the
Client-Server API, but was being leaked when a federation response
was used in the /hierarchy API.
If we locally generate a rejection for an invite received over federation, it
is stored as an outlier (because we probably don't have the state for the
room). However, currently we still generate a state group for it (even though
the state in that state group will be nonsense).
By setting the `outlier` param on `create_event`, we avoid the nonsensical
state.
I've argued in #11537 that poetry and tox don't cooperate well at the
moment. (See also #12119.) Therefore I'm pruning away bits of tox to make the transition to poetry easier. This change removes the commands for coverage.
We don't use coverage in anger at the moment. It shouldn't be too hard to add coverage as a dev-dependency and reintroduce this if we really want it.
* Move the `snapcraft` configuration to `contrib`.
We're happy for people to package this as a snap image if it's useful,
but we don't support or maintain it. I'd like to move the config to
`contrib` to reflect this state of affairs.
* Changelog
* Remove unused mocks from `test_typing`
It's not clear what these do. `get_user_by_access_token` has the wrong
signature, including the return type. Tests all pass without these. I
think we should nuke them.

# Setting up Synapse with Workers using Docker Compose
This directory describes how deploy and manage Synapse and workers via [Docker Compose](https://docs.docker.com/compose/).
Example worker configuration files can be found [here](workers).
All examples and snippets assume that your Synapse service is called `synapse` in your Docker Compose file.
An example Docker Compose file can be found [here](docker-compose.yaml).
## Worker Service Examples in Docker Compose
In order to start the Synapse container as a worker, you must specify an `entrypoint` that loads both the `homeserver.yaml` and the configuration for the worker (`synapse-generic-worker-1.yaml` in the example below). You must also include the worker type in the environment variable `SYNAPSE_WORKER` or alternatively pass `-m synapse.app.generic_worker` as part of the `entrypoint` after `"/start.py", "run"`).
- ${VOLUME_PATH}/data:/data:rw# Replace VOLUME_PATH with the path to your Synapse volume
environment:
SYNAPSE_WORKER:synapse.app.federation_sender
depends_on:
- synapse
```
## `homeserver.yaml` Configuration
### Enable Redis
Locate the `redis` section of your `homeserver.yaml` and enable and configure it:
```yaml
redis:
enabled:true
host:redis
port:6379
# password: <secret_password>
```
This assumes that your Redis service is called `redis` in your Docker Compose file.
### Add a replication Listener
Locate the `listeners` section of your `homeserver.yaml` and add the following replication listener:
```yaml
listeners:
# Other listeners
- port:9093
type:http
resources:
- names:[replication]
```
This listener is used by the workers for replication and is referred to in worker config files using the following settings:
```yaml
worker_replication_host:synapse
worker_replication_http_port:9093
```
### Add Workers to `instance_map`
Locate the `instance_map` section of your `homeserver.yaml` and populate it with your workers:
```yaml
instance_map:
synapse-generic-worker-1:# The worker_name setting in your worker configuration file
host:synapse-generic-worker-1# The name of the worker service in your Docker Compose file
port:8034# The port assigned to the replication listener in your worker config file
synapse-federation-sender-1:
host:synapse-federation-sender-1
port:8034
```
### Configure Federation Senders
This section is applicable if you are using Federation senders (synapse.app.federation_sender). Locate the `send_federation` and `federation_sender_instances` settings in your `homeserver.yaml` and configure them:
```yaml
# This will disable federation sending on the main Synapse instance
send_federation:false
federation_sender_instances:
- synapse-federation-sender-1# The worker_name setting in your federation sender worker configuration file
```
## Other Worker types
Using the concepts shown here it is possible to create other worker types in Docker Compose. See the [Workers](https://matrix-org.github.io/synapse/latest/workers.html#available-worker-applications) documentation for a list of available workers.
