Otherwise I get this beautiful stacktrace:

Synapse 1.47.0rc3 (2021-11-16)
==============================

Bugfixes
--------

- Fix a bug introduced in 1.47.0rc1 which caused worker processes to not halt startup in the presence of outstanding database migrations. ([\#11346](https://github.com/matrix-org/synapse/issues/11346))
- Fix a bug introduced in 1.47.0rc1 which prevented the 'remove deleted devices from `device_inbox` column' background process from running when updating from a recent Synapse version. ([\#11303](https://github.com/matrix-org/synapse/issues/11303), [\#11353](https://github.com/matrix-org/synapse/issues/11353))

Different users may be allowed to see different rooms within a space,
so sharing responses between users is inadvisable.

This is one of the changes required to support Matrix 1.1

It already seems to pass mypy. I wonder what changed, given that it was
on the exclusion list. So this commit consists of me ensuring
`--disallow-untyped-defs` passes and a minor fixup to a function that
returned either `True` or `None`.

I was sad that I couldn't do better for
`_curr_state_delta_stream_cache`. At least it's explicitly called out in
a comment with #TODO.

This was only checking the __init__ files in modules instead of
all files in a module, which don't pass yet.

* Prefer `HTTPStatus` over plain `int`

This is an Opinion that no-one has seemed to object to yet.

* `--disallow-untyped-defs` for `tests.rest.client.test_directory`
* Improve synapse's annotations for deleting aliases
* Test case for deleting a room alias
* Changelog

* change display names/avatar URLS to None if they contain null bytes

* add changelog

* add POC test, requested changes

* add a saner test and remove old one

* update test to verify that display name has been changed to None

* make test less fragile

* Make DataStore inherit from EventForwardExtremitiesStore before CacheInvalidationWorkerStore

the former implicitly inherits from the latter, so they should be
ordered like this when used.

* Annotate HomeserverTestCase.servlets
* Correct annotation of federation_auth_origin
* Use AnyStr custom_headers instead of a Union

This allows (str, str) and (bytes, bytes).
This disallows (str, bytes) and (bytes, str)

* DomainSpecificString.SIGIL is a ClassVar

I'm not sure why this was excluded---it seemed to be passing for me. But
it's easy enough to fixup.
