If simple_{insert,upsert,update}_many_txn is called without any data
to modify then return instead of executing the query.
This matches the behavior of simple_{select,delete}_many_txn.
* More precise type for LoggingTransaction.execute
* Add an annotation for stream_ordering_month_ago
This would have spotted the error that was fixed in "Add comma missing from #15382. (#15429)"
* Batch look-ups to see if rooms are partial stated.
* Fix issues found in linting.
* Fix typo.
* Apply suggestions from code review

* Also improve the cache size while we're at it
* is_partial_state_rooms -> is_partial_state_room_batched
* Run `black`
* Improve annotation for `simple_select_many_batch`
* Fix is_partial_state_room_batched impl

Doesn't do much but helps me sleep better at night.
* Changelog
* Fix name of the ignore
* Fix one more missed cast
Not sure why I didn't see this one locally, maybe I needed a poetry update
* Remove old comment

To perform an emulated upsert into a table safely, we must either:
* lock the table,
* be the only writer upserting into the table
* or rely on another unique index being present.
When the 2nd or 3rd cases were applicable, we previously avoided locking
the table as an optimization. However, as seen in #14406, it is easy to
slip up when adding new schema deltas and corrupt the database.
The only time we lock when performing emulated upserts is while waiting
for background updates on postgres. On sqlite, we do no locking at all.
Let's remove the option to skip locking tables, so that we don't shoot
ourselves in the foot again.

When a local device list change is added to
`device_lists_changes_in_room`, the `converted_to_destinations` flag is
set to `FALSE` and the `_handle_new_device_update_async` background
process is started. This background process looks for unconverted rows
in `device_lists_changes_in_room`, copies them to
`device_lists_outbound_pokes` and updates the flag.
To update the `converted_to_destinations` flag, the database performs a
`DELETE` and `INSERT` internally, which fragments the table. To avoid
this, track unconverted rows using a `(stream ID, room ID)` position
instead of the flag.
From now on, the `converted_to_destinations` column indicates rows that
need converting to outbound pokes, but does not indicate whether the
conversion has already taken place.
Closes#14037.

When retrieving counts of notifications segment the results based on the
thread ID, but choose whether to return them as individual threads or as
a single summed field by letting the client opt-in via a sync flag.
The summarization code is also updated to be per thread, instead of per
room.
Instead of running a single large query, run a single query for
user-only lookups and additional queries for batches of user device
lookups.
Resolves#13580.

This reverts commit f383b9b3ec. Other PRs
were seeing mypy failures that looked to be related to mypy-zope.
Confusingly, we didn't see this on #13521.
Revert this for now and investigate later.
Fix race conditions in the async cache invalidation logic, by separating
the async & local invalidation calls and ensuring any async call i
executed first.
