Revert "Add background job to clear unreferenced state groups (#18154)"
This mechanism is suspected of inserting large numbers of rows into
`state_groups_state`,
thus unreasonably increasing disk usage.
See: https://github.com/element-hq/synapse/issues/18217
This reverts commit 5121f9210c (#18154).

The context for this is that the Matrix spec allows basically anything
in the device ID. With MSC3861, we're restricting this to strings that
can be represented as scopes.
Whilst this works well for next-gen auth sessions, compatibility/legacy
sessions still can have characters that can't be encoded (mainly spaces)
in them.
To work around that, we added in MAS a behaviour where the device_id is
given as an explicit property of the token introspection response, and
remove it from the scope.
Because we don't expect users to rollout new Synapse and MAS versions in
sync, we needed a way to 'advertise' support for this behaviour: the
easiest way to do that was through an extra header in the introspection
response.
On the longer term, I expect MAS and Synapse to move away from the
introspection endpoint, and instead define a specific API for Synapse ->
MAS communication.
PR on the MAS side:
https://github.com/element-hq/matrix-authentication-service/pull/4067
Allows overriding the `redirect_uri` parameter sent to both the
authorization and token endpoints of the IdP. Typically this parameter
is hardcoded to `<public_baseurl>/_synapse/client/oidc/callback`.
Yet it can be useful in certain contexts to allow a different callback
URL. For instance, if you would like to intercept the authorization code
returned from the IdP and do something with it, before eventually
calling Synapse's OIDC callback URL yourself.
This change enables enterprise use cases but does not change the default
behaviour.

MSC4108 relies on ETag to determine if something has changed on the
rendez-vous channel.
Strong and correct ETag comparison works if the response body is
bit-for-bit identical, which isn't the case if a proxy in the middle
compresses the response on the fly.
This adds a `no-transform` directive to the `Cache-Control` header,
which tells proxies not to transform the response body.
Additionally, some proxies (nginx) will switch to `Transfer-Encoding:
chunked` if it doesn't know the Content-Length of the response, and
'weakening' the ETag if that's the case. I've added `Content-Length`
headers to all responses, to hopefully solve that.
This basically fixes QR-code login when nginx or cloudflare is involved,
with gzip/zstd/deflate compression enabled.
Normally, when `discovery` is enabled,
`id_token_signing_alg_values_supported` comes from the OpenID Discovery
Document (`/.well-known/openid-configuration`). If nothing was
specified, we default to supporting `RS256` in the downstream usage.
This PR just adds support for adding a default/overriding the the
discovered value [just like we do for other things like the
`token_endpoint`](1525a3b4d4/docs/usage/configuration/config_documentation.md (oidc_providers)),
etc.
This is a split off #18033
This uses a few tricks to speed up the building of docker images:
- This switches to use `uv pip install` instead of `pip install`. This
saves a bunch of time, especially when cross-compiling
- I then looked at what packages were not using binary wheels: I
upgraded MarkupSafe to have binaries for py3.12, and got back to Python
3.12 because hiredis didn't have builds for py3.13 with the version we
were using
- The generation of the requirements.txt is arch-agnostic, so I've
switched this one to run on the build architecture, so that both arch
can share it
- The download of runtime depdendencies can be done on the build
architecture through manual `apt-get download` plus `dpkg --extract`
- We were using -slim images, but still installed a bunch of -dev
dependencies. Turns out, all the dev dependencies were already installed
in the non-slim image, which saves a bunch of time as well
This has been a problem with Element Web, as it will proble /register
with an empty body, which gave this error:
```
curl -d '{}' -HContent-Type:application/json /_matrix/client/v3/register
{"errcode": "M_UNKNOWN",
"error": "Invalid username"}
```
And Element Web would choke on it. This changes that so we reply
instead:
```
{"errcode": "M_FORBIDDEN",
"error": "Registration has been disabled. Only m.login.application_service registrations are allowed."}
```
Also adds a test for this.

Adds new environment variables that can be used with the Docker image
(`SYNAPSE_HTTP_PROXY`/`SYNAPSE_HTTPS_PROXY`/`SYNAPSE_NO_PROXY`)
Useful for things like the [Secure Border
Gateway](https://element.io/server-suite/secure-border-gateways)
### Why is this necessary?
You can already configure the `HTTP_PROXY`/`HTTPS_PROXY` environment
variables to proxy outbound requests but setting this globally in the
Docker image affects all processes which isn't always desirable or
workable in the case where the proxy is running in the Docker image
itself (because the Debian packages will fail to download because the
proxy isn't up and running yet) . Adding Synapse specific environment
variables
(`SYNAPSE_HTTP_PROXY`/`SYNAPSE_HTTPS_PROXY`/`SYNAPSE_NO_PROXY`) makes
things much more targetable.
If a user search has many words we can end up creating really large
queries that take a long time for the database to process. Generally,
such searches don't return any results anyway (due to limits on user ID
and display name length).
We "fix" this by cheating and only searching for the first ten words.
Document consequences of replacing secrets. The covered config options
are `registration_shared_secret`, `macaroon_secret_key`, `form_secret`
and `worker_replication_secret`.
Even though I looked at the source code to check the added documentation
is right, I would appreciate additional verification of the statements
made.
In an hand-wavy attempt at classifying how bad the consequences of
secret replacement are, I added some explanations as warnings and others
as regular paragraphs.
Closes#17971

This is to help track down a possible, but very rare, worker deadlock
that was seen on matrix.org.
In theory, you could work back from an instance of these new logs to the
approximate time when the lock was obtained and focus the diagnostic
efforts there.

I forgot the guide applies to Oracle Linux as well. In fact, I ran a
small homeserver on OEL a few months back.
I did minimal installations on Rocky and OEL on VirtualBox and noticed
Codeready/Powertools repos aren't required, so I removed those commands
from the guide. I switched `RHEL`-references to `EL`.
#17423 was merged before I remembered about OEL but a new PR shouldn't
hurt :)

Broke in #17916, as the signature inspection incorrectly looks at the
wrapper function. We fix this by setting the signature on the wrapper
function to that of the wrapped function via `@functools.wraps`.
Another PR on my quest to a `*_path` variant for every secret. Adds two
config options `admin_token_path` and `client_secret_path` to the
experimental config under `experimental_features.msc3861`. Also includes
tests.
I tried to be a good citizen here by following `attrs` conventions and
not rewriting the corresponding non-path variants in the class, but
instead adding methods to retrieve the value.
Reading secrets from files has the security advantage of separating the
secrets from the config. It also simplifies secrets management in
Kubernetes. Also useful to NixOS users.
When purging history, we try and delete any state groups that become
unreferenced (i.e. there are no longer any events that directly
reference them). When we delete a state group that is referenced by
another state group, we "de-delta" that state group so that it no longer
refers to the state group that is deleted.
There are two bugs with this approach that we fix here:
1. There is a common pattern where we end up storing two state groups
when persisting a state event: the state before and after the new state
event, where the latter is stored as a delta to the former. When
deleting state groups we only deleted the "new" state and left (and
potentially de-deltaed) the old state. This was due to a bug/typo when
trying to find referenced state groups.
2. There are times where we store unreferenced state groups in the DB,
during the purging of history these would not get rechecked and instead
always de-deltaed. Instead, we should check for this case and delete any
unreferenced state groups rather than de-deltaing them.
The effect of the above bugs is that when purging history we'd end up
with lots of unreferenced state groups that had been de-deltaed (i.e.
stored as the full state). This can lead to dramatic increases in
storage space used.
Currently we don't really have anything that stops us from deleting
state groups when an in-flight event references it. This is a fairly
rare race currently, but we want to be able to more aggressively delete
state groups so it is important to address this to ensure that the
database remains valid.
This implements the locking, but doesn't actually use it.
See the class docstring of the new data store for an explanation for how
this works.

This is so workers can call these functions.
This was preventing the [Delete Room Admin
API](https://element-hq.github.io/synapse/latest/admin_api/rooms.html#version-2-new-version)
from succeeding when `block: true` was specified. This was because we
had `run_background_tasks_on` configured to run on a separate worker.
As workers weren't able to call the `block_room` storage function before
this PR, the (delete room) task failed when taken off the queue by the
worker.
Previously, a value like `5q` would be interpreted as 5 milliseconds. We
should just raise an error instead of letting someone run with a
misconfiguration.
This PR changes the logic so that deactivated users are always ignored.
Suspended users were already effectively ignored as Synapse forbids a
join while suspended.
