There is a corner in `_check_event_auth` (long known as "the weird corner") where, if we get an event with auth_events which don't match those we were expecting, we attempt to resolve the diffence between our state and the remote's with a state resolution.
This isn't specced, and there's general agreement we shouldn't be doing it.
However, it turns out that the faster-joins code was relying on it, so we need to introduce something similar (but rather simpler) for that.
* Drop support for delegating email validation
Delegating email validation to an IS is insecure (since it allows the owner of
the IS to do a password reset on your HS), and has long been deprecated. It
will now cause a config error at startup.
* Update unit test which checks for email verification
Give it an `email` config instead of a threepid delegate
* Remove unused method `requestEmailToken`
* Simplify config handling for email verification
Rather than an enum and a boolean, all we need here is a single bool, which
says whether we are or are not doing email verification.
* update docs
* changelog
* upgrade.md: fix typo
* update version number
this will be in 1.64, not 1.63
* update version number
this one too
Inspired by the room batch handler, this uses previous event inserts to
pre-populate prev events during room creation, reducing the number of
queries required to create a room.

==============================
This release of Synapse adds a unique index to the `state_group_edges` table, in
order to prevent accidentally introducing duplicate information (for example,
because a database backup was restored multiple times). If your Synapse database
already has duplicate rows in this table, this could fail with an error and
require manual remediation.
Additionally, the signature of the `check_event_for_spam` module callback has changed.
The previous signature has been deprecated and remains working for now. Module authors
should update their modules to use the new signature where possible.
See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1600)

Makes it so that groups/communities no longer exist from a user-POV. E.g. we remove:
* All API endpoints (including Client-Server, Server-Server, and admin).
* Documented configuration options (and the experimental flag, which is now unused).
* Special handling during room upgrades.
* The `groups` section of the `/sync` response.
Parse the `m.relates_to` event content field (which describes relations)
in a single place, this is used during:
* Event persistence.
* Validation of the Client-Server API.
* Fetching bundled aggregations.
* Processing of push rules.
Each of these separately implement the logic and each made slightly
different assumptions about what was valid. Some had minor / potential
bugs.
Fixes a regression from 8b309adb43 (#11660)
and b65acead42 (#11752) where events which
themselves were an edit or an annotation could have bundled aggregations calculated,
which is not allowed.
* Changes hidden read receipts to be a separate receipt type
(instead of a field on `m.read`).
* Updates the `/receipts` endpoint to accept `m.fully_read`.
* `m.login.jwt`, which was never specced and has been deprecated
since Synapse 1.16.0. (`org.matrix.login.jwt` can be used instead.)
* `uk.half-shot.msc2778.login.application_service`, which was
stabilized as part of the Matrix spec v1.2 release.
The `latest_event` field of the bundled aggregations for `m.thread` relations
did not include bundled aggregations itself. This resulted in clients needing to
immediately request the event from the server (and thus making it useless that
the latest event itself was serialized instead of just including an event ID).
When configuring the return values of mocks, prefer awaitables from
`make_awaitable` over `defer.succeed`. `Deferred`s are only awaitable
once, so it is inappropriate for a mock to return the same `Deferred`
multiple times.
Also update `run_in_background` to support functions that return
arbitrary awaitables.

Consider the requester's ignored users when calculating the
bundled aggregations.
See #12285 / 4df10d3214
for corresponding changes for the `/relations` endpoint.
There are a bunch of places we call get_success on an immediate value, which is unnecessary. Let's rip them out, and remove the redundant functionality in get_success and friends.
This endpoint was removed from MSC2675 before it was approved.
It is currently unspecified (even in any MSCs) and therefore subject to
removal. It is not implemented by any known clients.
This also changes the bundled aggregation format for `m.annotation`,
which previously included pagination tokens for the `/aggregations`
endpoint, which are no longer useful.
We fetch the thread summary in two phases:
1. The summary that is shared by all users (count of messages and latest event).
2. Whether the requesting user has participated in the thread.
There's no use in attempting step 2 for events which did not return a summary
from step 1.
An error occured if a filter was supplied with `event_fields` which did not include
`unsigned`.
In that case, bundled aggregations are still added as the spec states it is allowed
for servers to add additional fields.
* Moves the relation pagination tests to a separate class.
* Move the assertion of the response code into the `_send_relation` helper.
* Moves some helpers into the base-class.
The unstable identifiers are still supported if the experimental configuration
flag is enabled. The unstable identifiers will be removed in a future release.
This is allowed per MSC2675, although the original implementation did
not allow for it and would return an empty chunk / not bundle aggregations.
The main thing to improve is that the various caches get cleared properly
when an event is redacted, and that edits must not leak if the original
event is redacted (as that would presumably leak something similar to
the original event content).
* Remove unused mocks from `test_typing`
It's not clear what these do. `get_user_by_access_token` has the wrong
signature, including the return type. Tests all pass without these. I
think we should nuke them.
* Changelog
* Fixup imports
* Add type hints to `tests/rest/client`
* newsfile
* fix imports
* add `test_account.py`
* Remove one type hint in `test_report_event.py`
* change `on_create_room` to `async`

If the latest event in a thread was edited than the original
event content was included in bundled aggregation for
threads instead of the edited event content.
If ther are more than 100 to-device messages pending for a device
`/sync` will only return the first 100, however the next batch token was
incorrectly calculated and so all other pending messages would be
dropped.
This is due to `txn.rowcount` only returning the number of rows that
*changed*, rather than the number *selected* in SQLite.
If we prepopulate the test homeserver with a key for a remote homeserver, we
can make federation requests to it without having to stub out the
authenticator. This has two advantages:
* means that what we are testing is closer to reality (ie, we now have
complete tests for the incoming-request-authorisation flow)
* some tests require that other objects be signed by the remote server (eg,
the event in `/send_join`), and doing that would require a whole separate
set of mocking out. It's much simpler just to use real keys.
This implements an allow list for content types for which Synapse will attempt URL preview. If a URL resolves to a resource with a content type which isn't in the list, the download will terminate immediately.
This makes sense given that Synapse would never successfully generate a URL preview for such files in the first place, and helps prevent issues with streaming media servers, such as #8302.

Only allow files which file size and content types match configured

Most of the inspiration from the non-test code comes from matrix-org/synapse-dinsic#19
This is some odds and ends found during the review of #11791
and while continuing to work in this code:
* Return attrs classes instead of dictionaries from some methods
to improve type safety.
* Call `get_bundled_aggregations` fewer times.
* Adds a missing assertion in the tests.
* Do not return empty bundled aggregations for an event (preferring
to not include the bundle at all, as the docstring states).
This is mostly motivated by the tchap use case, where usernames are automatically generated from the user's email address (in a way that allows figuring out the email address from the username). Therefore, it's an issue if we respond to requests on /register and /register/available with M_USER_IN_USE, because it can potentially leak email addresses (which include the user's real name and place of work).
This commit adds a flag to inhibit the M_USER_IN_USE errors that are raised both by /register/available, and when providing a username early into the registration process. This error will still be raised if the user completes the registration process but the username conflicts. This is particularly useful when using modules (https://github.com/matrix-org/synapse/pull/11790 adds a module callback to set the username of users at registration) or SSO, since they can ensure the username is unique.
More context is available in the PR that introduced this behaviour to synapse-dinsic: matrix-org/synapse-dinsic#48 - as well as the issue in the matrix-dinsic repo: matrix-org/matrix-dinsic#476
Always add state.room_id after the configurable ORDER BY. Otherwise,
for any sort, certain pages can contain results from
other pages. (Especially when sorting by creator, since there may
be many rooms by the same creator)
* Document different order direction of numerical fields
"joined_members", "joined_local_members", "version" and "state_events"
are ordered in descending direction by default (dir=f). Added a note
in tests to explain the differences in ordering.

This makes the serialization of events synchronous (and it no
longer access the database), but we must manually calculate and
provide the bundled aggregations.
Overall this should cause no change in behavior, but is prep work
for other improvements.
* Disable aggregation bundling on `/sync` responses
A partial revert of #11478. This turns out to have had a significant CPU impact
on initial-sync handling. For now, let's disable it, until we find a more
efficient way of achieving this.
* Fix tests.
