When there have been lots of changes compared with the number of
entities, we can do a fast(er) path.
Locally I ran some benchmarking, and the comparison seems to give the
best determination of which method we use.
This change will apply the `email` & `picture` provided by OIDC to the
new user account when registering a new user via OIDC. If the user is
directed to the account details form, this change makes sure they have
been selected before applying them, otherwise they are omitted. In
particular, this change ensures the values are carried through when
Synapse has consent configured, and the redirect to the consent form/s
are followed.
I have tested everything manually. Including:
- with/without consent configured
- allowing/not allowing the use of email/avatar (via
`sso_auth_account_details.html`)
- with/without automatic account detail population (by un/commenting the
`localpart_template` option in synapse config).

before submitting your pull request -->
* [X] Pull request is based on the develop branch
* [X] Pull request includes a [changelog
file](https://element-hq.github.io/synapse/latest/development/contributing_guide.html#changelog).
The entry should:
- Be a short description of your change which makes sense to users.
"Fixed a bug that prevented receiving messages from other servers."
instead of "Moved X method from `EventStore` to `EventWorkerStore`.".
- Use markdown where necessary, mostly for `code blocks`.
- End with either a period (.) or an exclamation mark (!).
- Start with a capital letter.
- Feel free to credit yourself, by adding a sentence "Contributed by
@github_username." or "Contributed by [Your Name]." to the end of the
entry.
* [X] [Code
style](https://element-hq.github.io/synapse/latest/code_style.html) is
correct

... when workers are unreachable, etc.
Fixes https://github.com/element-hq/synapse/issues/17117.
The general principle is just to make sure that we propagate any
exceptions to the JsonResource, so that we return an error code to the
sending server. That means that the sending server no longer considers
the message safely sent, so it will retry later.
In the issue, Erik mentions that an alternative solution would be to
persist the to-device messages into a table so that they can be retried.
This might be an improvement for performance, but even if we did that,
we still need this mechanism, since we might be unable to reach the
database. So, if we want to do that, it can be a later follow-up.

This makes it easy to store UNIX sockets with correct permissions. Those
would be located in /run/synapse which is the directory used in many
examples in Synapse configuration manual. Additionally, the directory
and sockets are deleted when Synapse is shut down.
This adds functions to transform a Twisted request to the
`http::Request`, and then to send back an `http::Response` through it.
It also imports the SynapseError exception so that we can throw that
from Rust code directly
Example usage of this would be:
```rust
use crate::http::{http_request_from_twisted, http_response_to_twisted, HeaderMapPyExt};
fn handler(twisted_request: &PyAny) -> PyResult<()> {
let request = http_request_from_twisted(twisted_request)?;
let ua: headers::UserAgent = request.headers().typed_get_required()?;
if whatever {
return Err((crate::errors::SynapseError::new(
StatusCode::UNAUTHORIZED,
"Whatever".to_owned
"M_UNAUTHORIZED",
None,
None,
)));
}
let response = Response::new("hello".as_bytes());
http_response_to_twisted(twisted_request, response)?;
Ok(())
}
```
Resurrecting https://github.com/matrix-org/synapse/pull/13918.
This should reduce IOPs incurred by joining to the events table to
lookup stream ordering, which happens in many receipt handling code
paths. Like the previous PR I believe sufficient time has passed between
the original migration in DB schema 72 and now to merge this as-is. It's
highly unlikely that both the migration is still ongoing AND (active)
users still have any receipts prior to that date.
In the unlikely event there is a receipt without a populated
`event_stream_ordering` synapse will behave just as it does now when
receipts exist for events that don't (yet): for push action calculation
the receipts are just ignored.
I've removed the validation on event IDs as this is already covered
here:
59ceabcb97/synapse/handlers/receipts.py (L189-L192)
PR #16942 removed an invalid optimisation that avoided pulling out state
for non-gappy syncs. This causes a large increase in DB usage. c.f.
#16941 for why that optimisation was wrong.
However, we can still optimise in the simple case where the events in
the timeline are a linear chain without any branching/merging of the
DAG.

Before we were pulling out *all* read receipts for a user for every
event we pushed. Instead let's only pull out the relevant receipts.
This also pulled out the event rows for each receipt, causing load on
the events table.
