Born out of trying to test a particular condition in #11905.

There's some duplication between these methods, though not so much that I think refactoring it out is sorely needed. Feel free to refute that claim though!

Otherwise LGTM

# receiving device list updates for that room.
# In order to test the case where Bob has previously been joined to the room,
# instead of restarting Synapse, we can just stub out the notifier machinery
# that is triggered when a user joins a room.

I'm fairly dubious about doing this, as it really is wrenching into the guts of the code and changing things (rather than just mocking out an interface). Why do we need this? My reading of the code is that _user_joined_room will only have an effect if the user is currently syncing when they joined the room?

Hmm, a user stream entry is created when a user syncs, but I fail to see where it's removed at the end of a sync. I only see streams being removed when they expire:

expired_stream.remove(self)

Nevertheless, putting in a breakpoint here resulted in no trigger when running the full test, so this is indeed not necessary! Removed in edc28b0.

It happens here:

synapse/synapse/notifier.py

Lines 155 to 164 in 5de46ac

def remove(self, notifier: "Notifier"):
"""Remove this listener from all the indexes in the Notifier
it knows about.
"""
for room in self.rooms:
lst = notifier.room_to_user_streams.get(room, set())
lst.discard(self)
notifier.user_to_user_stream.pop(self.user_id)

(I spent a while tracking that down)

Right, though the only code I can see that calls this is remove_expired_streams.

Oh, that seems odd that it doesn't get removed when the stream gets notified 🤷

Turns out this was not necessary\!

Synapse 1.54.0rc1 (2022-03-02)
==============================

Please note that this will be the last release of Synapse that is compatible with Mjolnir 1.3.1 and earlier.
Administrators of servers which have the Mjolnir module installed are advised to upgrade Mjolnir to version 1.3.2 or later.

Features
--------

- Add support for [MSC3202](matrix-org/matrix-spec-proposals#3202): sending one-time key counts and fallback key usage states to Application Services. ([\#11617](#11617))
- Improve the generated URL previews for some web pages. Contributed by @AndrewRyanChama. ([\#11985](#11985))
- Track cache invalidations in Prometheus metrics, as already happens for cache eviction based on size or time. ([\#12000](#12000))
- Implement experimental support for [MSC3720](matrix-org/matrix-spec-proposals#3720) (account status endpoints). ([\#12001](#12001), [\#12067](#12067))
- Enable modules to set a custom display name when registering a user. ([\#12009](#12009))
- Advertise Matrix 1.1 and 1.2 support on `/_matrix/client/versions`. ([\#12020](#12020), ([\#12022](#12022))
- Support only the stable identifier for [MSC3069](matrix-org/matrix-spec-proposals#3069 `is_guest` on `/_matrix/client/v3/account/whoami`. ([\#12021](#12021))
- Use room version 9 as the default room version (per [MSC3589](matrix-org/matrix-spec-proposals#3589)). ([\#12058](#12058))
- Add module callbacks to react to user deactivation status changes (i.e. deactivations and reactivations) and profile updates. ([\#12062](#12062))

Bugfixes
--------

- Fix a bug introduced in Synapse 1.48.0 where an edit of the latest event in a thread would not be properly applied to the thread summary. ([\#11992](#11992))
- Fix long-standing bug where the `get_rooms_for_user` cache was not correctly invalidated for remote users when the server left a room. ([\#11999](#11999))
- Fix a 500 error with Postgres when looking backwards with the [MSC3030](matrix-org/matrix-spec-proposals#3030) `/timestamp_to_event?dir=b` endpoint. ([\#12024](#12024))
- Properly fix a long-standing bug where wrong data could be inserted into the `event_search` table when using SQLite. This could block running `synapse_port_db` with an `argument of type 'int' is not iterable` error. This bug was partially fixed by a change in Synapse 1.44.0. ([\#12037](#12037))
- Fix slow performance of `/logout` in some cases where refresh tokens are in use. The slowness existed since the initial implementation of refresh tokens in version 1.38.0. ([\#12056](#12056))
- Fix a long-standing bug where Synapse would make additional failing requests over federation for missing data. ([\#12077](#12077))
- Fix occasional `Unhandled error in Deferred` error message. ([\#12089](#12089))
- Fix a bug introduced in Synapse 1.51.0 where incoming federation transactions containing at least one EDU would be dropped if debug logging was enabled for `synapse.8631_debug`. ([\#12098](#12098))
- Fix a long-standing bug which could cause push notifications to malfunction if `use_frozen_dicts` was set in the configuration. ([\#12100](#12100))
- Fix an extremely rare, long-standing bug in `ReadWriteLock` that would cause an error when a newly unblocked writer completes instantly. ([\#12105](#12105))
- Make a `POST` to `/rooms/<room_id>/receipt/m.read/<event_id>` only trigger a push notification if the count of unread messages is different to the one in the last successfully sent push. This reduces server load and load on the receiving device. ([\#11835](#11835))

Updates to the Docker image
---------------------------

- The Docker image no longer automatically creates a temporary volume at `/data`. This is not expected to affect normal usage. ([\#11997](#11997))
- Use Python 3.9 in Docker images by default. ([\#12112](#12112))

Improved Documentation
----------------------

- Document support for the `to_device`, `account_data`, `receipts`, and `presence` stream writers for workers. ([\#11599](#11599))
- Explain the meaning of spam checker callbacks' return values. ([\#12003](#12003))
- Clarify information about external Identity Provider IDs. ([\#12004](#12004))

Deprecations and Removals
-------------------------

- Deprecate using `synctl` with the config option `synctl_cache_factor` and print a warning if a user still uses this option. ([\#11865](#11865))
- Remove support for the legacy structured logging configuration (please see the the [upgrade notes](https://matrix-org.github.io/synapse/develop/upgrade#legacy-structured-logging-configuration-removal) if you are using `structured: true` in the Synapse configuration). ([\#12008](#12008))
- Drop support for [MSC3283](matrix-org/matrix-spec-proposals#3283) unstable flags now that the stable flags are supported. ([\#12018](#12018))
- Remove the unstable `/spaces` endpoint from [MSC2946](matrix-org/matrix-spec-proposals#2946). ([\#12073](#12073))

Internal Changes
----------------

- Make the `get_room_version` method use `get_room_version_id` to benefit from caching. ([\#11808](#11808))
- Remove unnecessary condition on knock -> leave auth rule check. ([\#11900](#11900))
- Add tests for device list changes between local users. ([\#11972](#11972))
- Optimise calculating `device_list` changes in `/sync`. ([\#11974](#11974))
- Add missing type hints to storage classes. ([\#11984](#11984))
- Refactor the search code for improved readability. ([\#11991](#11991))
- Move common deduplication code down into `_auth_and_persist_outliers`. ([\#11994](#11994))

- Preparation for faster-room-join work: parse MSC3706 fields in send_join response. ([\#12011](#12011))
- Preparation for faster-room-join work: persist information on which events and rooms have partial state to the database. ([\#12012](#12012))
- Preparation for faster-room-join work: Support for calling `/federation/v1/state` on a remote server. ([\#12013](#12013))
- Configure `tox` to use `venv` rather than `virtualenv`. ([\#12015](#12015))
- Fix bug in `StateFilter.return_expanded()` and add some tests. ([\#12016](#12016))
- Use Matrix v1.1 endpoints (`/_matrix/client/v3/auth/...`) in fallback auth HTML forms. ([\#12019](#12019))
- Update the `olddeps` CI job to use an old version of `markupsafe`. ([\#12025](#12025))
- Upgrade Mypy to version 0.931. ([\#12030](#12030))
- Remove legacy `HomeServer.get_datastore()`. ([\#12031](#12031), [\#12070](#12070))
- Minor typing fixes. ([\#12034](#12034), [\#12069](#12069))

- Support only the stable identifier for [MSC3069](matrix-org/matrix-spec-proposals#3069 `is_guest` on `/_matrix/client/v3/account/whoami`. ([\#12021](matrix-org/synapse#12021))
- Use room version 9 as the default room version (per [MSC3589](matrix-org/matrix-spec-proposals#3589)). ([\#12058](matrix-org/synapse#12058))
- Add module callbacks to react to user deactivation status changes (i.e. deactivations and reactivations) and profile updates. ([\#12062](matrix-org/synapse#12062))

Bugfixes
--------

- Fix a bug introduced in Synapse 1.48.0 where an edit of the latest event in a thread would not be properly applied to the thread summary. ([\#11992](matrix-org/synapse#11992))
- Fix long-standing bug where the `get_rooms_for_user` cache was not correctly invalidated for remote users when the server left a room. ([\#11999](matrix-org/synapse#11999))
- Fix a 500 error with Postgres when looking backwards with the [MSC3030](matrix-org/matrix-spec-proposals#3030) `/timestamp_to_event?dir=b` endpoint. ([\#12024](matrix-org/synapse#12024))
- Properly fix a long-standing bug where wrong data could be inserted into the `event_search` table when using SQLite. This could block running `synapse_port_db` with an `argument of type 'int' is not iterable` error. This bug was partially fixed by a change in Synapse 1.44.0. ([\#12037](matrix-org/synapse#12037))
- Fix slow performance of `/logout` in some cases where refresh tokens are in use. The slowness existed since the initial implementation of refresh tokens in version 1.38.0. ([\#12056](matrix-org/synapse#12056))
- Fix a long-standing bug where Synapse would make additional failing requests over federation for missing data. ([\#12077](matrix-org/synapse#12077))
- Fix occasional `Unhandled error in Deferred` error message. ([\#12089](matrix-org/synapse#12089))
- Fix a bug introduced in Synapse 1.51.0 where incoming federation transactions containing at least one EDU would be dropped if debug logging was enabled for `synapse.8631_debug`. ([\#12098](matrix-org/synapse#12098))
- Fix a long-standing bug which could cause push notifications to malfunction if `use_frozen_dicts` was set in the configuration. ([\#12100](matrix-org/synapse#12100))
- Fix an extremely rare, long-standing bug in `ReadWriteLock` that would cause an error when a newly unblocked writer completes instantly. ([\#12105](matrix-org/synapse#12105))
- Make a `POST` to `/rooms/<room_id>/receipt/m.read/<event_id>` only trigger a push notification if the count of unread messages is different to the one in the last successfully sent push. This reduces server load and load on the receiving device. ([\#11835](matrix-org/synapse#11835))

Updates to the Docker image
---------------------------

- The Docker image no longer automatically creates a temporary volume at `/data`. This is not expected to affect normal usage. ([\#11997](matrix-org/synapse#11997))
- Use Python 3.9 in Docker images by default. ([\#12112](matrix-org/synapse#12112))

Improved Documentation
----------------------

- Document support for the `to_device`, `account_data`, `receipts`, and `presence` stream writers for workers. ([\#11599](matrix-org/synapse#11599))
- Explain the meaning of spam checker callbacks' return values. ([\#12003](matrix-org/synapse#12003))
- Clarify information about external Identity Provider IDs. ([\#12004](matrix-org/synapse#12004))

Deprecations and Removals
-------------------------

- Deprecate using `synctl` with the config option `synctl_cache_factor` and print a warning if a user still uses this option. ([\#11865](matrix-org/synapse#11865))
- Remove support for the legacy structured logging configuration (please see the the [upgrade notes](https://matrix-org.github.io/synapse/develop/upgrade#legacy-structured-logging-configuration-removal) if you are using `structured: true` in the Synapse configuration). ([\#12008](matrix-org/synapse#12008))
- Drop support for [MSC3283](matrix-org/matrix-spec-proposals#3283) unstable flags now that the stable flags are supported. ([\#12018](matrix-org/synapse#12018))
- Remove the unstable `/spaces` endpoint from [MSC2946](matrix-org/matrix-spec-proposals#2946). ([\#12073](matrix-org/synapse#12073))

Internal Changes
----------------

- Limit concurrent joins from applications services. ([\#11996](matrix-org/synapse#11996))
- Preparation for faster-room-join work: when parsing the `send_join` response, get the `m.room.create` event from `state`, not `auth_chain`. ([\#12005](matrix-org/synapse#12005), [\#12039](matrix-org/synapse#12039))
- Preparation for faster-room-join work: parse MSC3706 fields in send_join response. ([\#12011](matrix-org/synapse#12011))
- Preparation for faster-room-join work: persist information on which events and rooms have partial state to the database. ([\#12012](matrix-org/synapse#12012))
- Preparation for faster-room-join work: Support for calling `/federation/v1/state` on a remote server. ([\#12013](matrix-org/synapse#12013))

- Minor typing fixes. ([\#12034](matrix-org/synapse#12034), [\#12069](matrix-org/synapse#12069))
- After joining a room, create a dedicated logcontext to process the queued events. ([\#12041](matrix-org/synapse#12041))
- Tidy up GitHub Actions config which builds distributions for PyPI. ([\#12051](matrix-org/synapse#12051))
- Move configuration out of `setup.cfg`. ([\#12052](matrix-org/synapse#12052), [\#12059](matrix-org/synapse#12059))
- Fix error message when a worker process fails to talk to another worker process. ([\#12060](matrix-org/synapse#12060))

- Add type hints to `tests/rest/client`. ([\#12066](matrix-org/synapse#12066), [\#12072](matrix-org/synapse#12072), [\#12084](matrix-org/synapse#12084), [\#12094](matrix-org/synapse#12094))
- Add some logging to `/sync` to try and track down #11916. ([\#12068](matrix-org/synapse#12068))
- Inspect application dependencies using `importlib.metadata` or its backport. ([\#12088](matrix-org/synapse#12088))
