If you leave a room and forget it, then rejoin it, the room would be
missing from the next initial sync.

The port DB script would try and run database background tasks, which
could fail if the data they acted on was in the process of being ported.
These exceptions were non fatal.
Fixes#15789
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.

* 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.

This manifests as purple lines that show up on all time series panels
that you can hover and see what version was deployed.
Also added a new "Deployed Synapse versions over time" panel
where the color block changes with each version. And mixed this
color block into the "Up" time series panel.
To get the Grafana dashboard JSON to copy here: use the **Share** icon at the top -> **Export** -> check the **Export for sharing externally** option -> **View JSON** or **Save to file**
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).
* Fully qualified docker image names for the main Dockerfile and Complement related.
* Fully qualified docker image names for Dockerfiles associated with building Debian release artifacts.
This one is harder and is separate from the other commit in case it wasn't correct or was unwanted. I decided to
do the expansion on the docker images in the Dockerfile itself, instead of the various source places that build
which distribution that is selected, as it would have been more invasive with the scripts breaking up the string
for tagging and such. This one is untested.
* Changelog
* Update docker/Dockerfile-workers
* Update docker/complement/Dockerfile

Fix#15667
- Reiterate the importance of getting Rust installed and set up before attempting to install the Python dependencies.
- Mention the importance of confirming that `poetry install` completed successfully and include a typical error that the user might see if it did not.
- Expand on "Now edit homeserver.yaml" to give examples of things likely to need changing and to link to the relevant sections of the Synapse server documentation.
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.
Each table is updated as a separate schema delta to avoid
deadlocks between them.
For SQLite we simply rebuild the table & copy the data.
The cached decorators always return a Deferred, which was not
properly propagated. It was close enough when wrapping coroutines,
but failed if a bare function was wrapped.

This moves the deactivated user check to the method which
all login types call.
Additionally updates the application service tests to be more
realistic by removing invalid tests and fixing server names.
All the information needed is already in the `instance_map`, so
use that instead of passing the hostname / IP & port manually
for each replication request.
This consolidates logic for future improvements of using e.g.
UNIX sockets for workers.

### Dev notes
The `Twisted.Logger` controls the `2023-05-19 18:16:20-0500 [-]` prefix, see : [`twisted/twisted` -> `src/twisted/logger/_format.py#L362-L374`](34b161e66b/src/twisted/logger/_format.py (L362-L374))
And we delegate our logs to the Twisted Logger for the tests which puts it in `_trial_temp/test.log`
The event_fields property in filters should use the proper
escape rules, namely backslashes can be escaped with
an additional backslash.
This adds tests (adapted from matrix-js-sdk) and implements
the logic to properly split the event_fields strings.
...to try to control memory usage. `HomeServerConfig`s hold on to
many Jinja2 objects, which come out to over 0.5 MiB per config.
Over the course of a full test run, the cache grows to ~360 entries.

Instrument `state` and `state_group` storage related things (tracing) so it's a little more clear where these database transactions are coming from as there is a lot of wires crossing in these functions.
Part of `/messages` performance investigation: https://github.com/matrix-org/synapse/issues/13356
R30v2 has been out since 2021-07-19 (https://github.com/matrix-org/synapse/pull/10332)
and we started collecting stats on 2021-08-16. Since it's been over a year now
(almost 2 years), this is enough grace period for us to now rip it out.
Synapse will no longer send (or respond to) the unstable flags
for faster joins. These were only available behind a configuration
flag and handled in parallel with the stable flags.
This change fixes two memory leaks during `trial` test runs.
Garbage collection is disabled during each test case and a gen-0 GC is
run at the end of each test. However, when the gen-0 GC is run, the
`TestCase` object usually still holds references to the `HomeServer`
used during the test. As a result, the `HomeServer` gets promoted to
gen-1 and then never garbage collected.
Fix this by periodically running full GCs.
Additionally, fix `HomeServer`s leaking after tests that touch inbound
federation due to `FederationRateLimiter`s adding themselves to a global
set, by turning the set into a `WeakSet`.
Resolves#15622.

If the previous read marker is pointing to an event that no longer exists
(e.g. due to retention) then assume that the newly given read marker
is newer.
To track changes in MSC2666:
- The change from `/mutual_rooms/{user_id}` to `/mutual_rooms?user_id={user_id}`.
- The addition of `next_batch_token` (and logic).
- Unstable flag now being `uk.half-shot.msc2666.query_mutual_rooms`.
- The error code when your own user is requested.
The second argument of `ConfigError` is a path, passed as an optional
`Iterable[str]` and not a `str`. If a string is passed directly,
Synapse unhelpfully emits "Error in configuration at
a.p.p._.s.e.r.v.i.c.e._.c.o.n.f.i.g._.f.i.l.e.s'" when the config
option has the wrong data type.

There are two situations which were previously not properly checked:
1. If the requested URL was replaced with an oEmbed URL, then the
oEmbed URL was not checked against url_preview_url_blacklist.
2. Follow-up URLs (either via autodiscovery of oEmbed or to pre-cache
images) were not checked against url_preview_url_blacklist.
