I had one of these error messages yesterday and assumed it was an
invalid auth token (because that was an HTTP query parameter in the
test) I was working on. In fact, it was an invalid next batch token for
syncing.
We've already batched up the events previously, and assume in other
places in the events.py file that we have. Removing this makes it easier
to adjust the batch sizes in one place.
Hint to clients via the room capabilities API (MSC3244) that
room version 9 should be preferred for creating a room with
restricted join rules (instead of room version 8).
* Split up the documentation in several files rather than one huge one

When releasing 1.42.0 with @Azrenbeth and talking with @clokep yesterday I realised doing the dch incantations related to releasing Synapse wasn't trivial on eg a macOS system, so this is a script to run in a Debian container to make things a bit easier.
This adds the format to the request arguments / URL to
ensure that JSON data is returned (which is all that
Synapse supports).
This also adds additional error checking / filtering to the
configuration file to ignore XML-only providers.
I think I have finally teased apart the codepaths which handle outliers, and those that handle non-outliers.
Let's add some assertions to demonstrate my newfound knowledge.
If we're persisting an event E which has auth_events A1, A2, then we ought to make sure that we correctly auth
and persist A1 and A2, before we blindly accept E.
This PR does part of that - it persists the auth events first - but it does not fully solve the problem, because we
still don't check that the auth events weren't rejected.
The full event content cannot be trusted from this API (as no auth
chain, etc.) is processed over federation. Returning the full event
content was a bug as MSC2946 specifies that only the stripped
state should be returned.
This also avoids calculating aggregations / annotations which go
unused.
This is part of my ongoing war against BaseHandler. I've moved kick_guest_users into RoomMemberHandler (since it calls out to that handler anyway), and split maybe_kick_guest_users into the two places it is called.
* Allow room creator to send MSC2716 related events in existing room versions

44bb3f0cf5
* Add changelog
* Stop people from trying to redact MSC2716 events in unsupported room versions
* Populate rooms.creator column for easy lookup
> From some [out of band discussion](https://matrix.to/#/!UytJQHLQYfvYWsGrGY:jki.re/$p2fKESoFst038x6pOOmsY0C49S2gLKMr0jhNMz_JJz0?via=jki.re&via=matrix.org), my plan is to use `rooms.creator`. But currently, we don't fill in `creator` for remote rooms when a user is invited to a room for example. So we need to add some code to fill in `creator` wherever we add to the `rooms` table. And also add a background update to fill in the rows missing `creator` (we can use the same logic that `get_create_event_for_room_txn` is doing by looking in the state events to get the `creator`).

We use `txn.fetchall` because it will return the results as a
list or an empty list when there are no results.
Docs:
> `cursor` objects are iterable, so, instead of calling explicitly fetchone() in a loop, the object itself can be used:
>
> https://www.psycopg.org/docs/cursor.html#cursor-iterable
And I'm guessing iterating over a raw cursor does something weird when there are no results.

* Move code not under the MSC2716 room version underneath an experimental config option

* Use constant field
This updates the ordering of the returned events from the spaces
summary API to that defined in MSC2946 (which updates MSC1772).
Previously a step was skipped causing ordering to be inconsistent with
clients.
Judging by the template, this was intended ages ago, but we never
actually passed an avatar URL to the template. So let's provide one.
Closes#1546.

Use `gc.freeze()` on exit to exclude all existing objects from the final GC.
In testing, this sped up shutdown by up to a few seconds.
`gc.freeze()` runs in constant time, so there is little chance of performance
regression.

Turns out that the functionality added in #10546 to skip TLS was incompatible
with older Twisted versions, so we need to be a bit more inventive.
Also, add a test to (hopefully) not break this in future. Sadly, testing TLS is
really hard.
- Removed page summaries from CONTRIBUTING and installation pages as
this information was already in the table of contents on the right hand side
- Fixed some broken links in CONTRIBUTING
- Added margin-right tag for when table of contents is being shown
(otherwise the text in the page sometimes overlaps with it)
The code to deduplicate repeated fetches of the same set of events was
N^2 (over the number of events requested), which could lead to a process
being completely wedged.
The main fix is to deduplicate the returned deferreds so we only await
on a deferred once rather than many times. Seperately, when handling the
returned events from the defrered we only add the events we care about
to the event map to be returned (so that we don't pay the price of
inserting extraneous events into the dict).
Given that backfill and get_missing_events are basically the same thing, it's somewhat crazy that we have entirely separate code paths for them. This makes backfill use the existing get_missing_events code, and then clears up all the unused code.
When a user deletes an email from their account it will
now also remove all pushers for that email and that user
(even if these pushers were created by a different client)
* Fix the titles in the OIDC documentation
Having them as links broke the table-of-contents rendering in mdbook.
Plus there's no reason for only some of the provider titles to be links.
* Changelog
* Add link to google idp docs
Setting `update_existing: true` in the `create-an-issue` GitHub Action
will avoid opening duplicate issues if an open issue already exists with
an identical title.
If no open issues match the title, then a new issue will be created.
This helps avoid spamming our issue tracker should there be a failure
when testing against Twisted's trunk.
This PR also pins the SHA of the `create-an-issue` action to mitigate
the risk of a malicious actor gaining access to JasonEtco's account.

* Validate device_keys for C-S /keys/query requests
Closes#10354
A small, not particularly critical fix. I'm interested in seeing if we
can find a more systematic approach though. #8445 is the place for any discussion.
Here we split on_receive_pdu into two functions (on_receive_pdu and process_pulled_event), rather than having both cases in the same method. There's a tiny bit of overlap, but not that much.
