This replaces the specific `is_room_mention` push rule condition
used in MSC3952 with the generic `exact_event_match` push rule
condition from MSC3758.
No functionality changes due to this.
It's important that collections returned from `@cached` methods are not
modified, otherwise future retrievals from the cache will return the
modified collection.
This applies to the return values from `@cached` methods and the values
inside the dictionaries returned by `@cachedList` methods. It's not
necessary for the dictionaries returned by `@cachedList` methods
themselves to be read-only.

This specifies to search for an exact value match, instead of
string globbing. It only works across non-compound JSON values
(null, boolean, integer, and strings).
This disambiguates keys which attempt to match fields
with a dot in them (e.g. m.relates_to).
Disabled by default behind an experimental configuration flag.
* Better test for bad values in power levels events
The previous test only checked that Synapse didn't raise an exception,
but didn't check that we had correctly interpreted the value of the
dodgy power level.
It also conflated two things: bad room notification levels, and bad user
levels. There _is_ logic for converting the latter to integers, but we
should test it separately.
* Check we ignore types that don't convert to int
* Handle `None` values in `notifications.room`
* Changelog
* Also test that bad values are rejected by event auth
* Docstring
* linter scripttttttttt
MSC3952 defines push rules which searches for mentions in a list of
Matrix IDs in the event body, instead of searching the entire event
body for display name / local part.
This is implemented behind an experimental configuration flag and
does not yet implement the backwards compatibility pieces of the MSC.
* Support MSC1767's `content.body` behaviour in push rules
* Add the base rules from MSC3933
* Changelog entry
* Flip condition around for finding `m.markup`
* Remove forgotten import
* Add support for MSC3931: Room Version Supports push rule condition
* Create experimental flag for future work, and use it to gate MSC3931
* Changelog entry
==============================
Please note that legacy Prometheus metric names are now deprecated and will be removed in Synapse 1.73.0.
Server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.

Deprecations and Removals
-------------------------
- Deprecate the `generate_short_term_login_token` method in favor of an async `create_login_token` method in the Module API. ([\#13842](https://github.com/matrix-org/synapse/issues/13842))
Internal Changes
----------------
- Ensure Synapse v1.69 works with upcoming database changes in v1.70. ([\#14045](https://github.com/matrix-org/synapse/issues/14045))
- Fix a bug introduced in Synapse v1.68.0 where messages could not be sent in rooms with non-integer `notifications` power level. ([\#14073](https://github.com/matrix-org/synapse/issues/14073))
- Temporarily pin build-system requirements to workaround an incompatibility with poetry-core 1.3.0. This will be reverted before the v1.69.0 release proper, see [\#14079](https://github.com/matrix-org/synapse/issues/14079). ([\#14080](https://github.com/matrix-org/synapse/issues/14080))

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.
We move the expensive check of visibility to after calculating push actions, avoiding the expensive check for users who won't get pushed anyway.
I think this should have a big impact on rooms with large numbers of local users that have pushed disabled.
Adds a `thread_id` column to the `event_push_actions`, `event_push_actions_staging`,
and `event_push_summary` tables. This will notifications to be segmented by the thread
in a future pull request. The `thread_id` column stores the root event ID or the special
value `"main"`.
The `thread_id` column for `event_push_actions` and `event_push_summary` is
backfilled with `"main"` for all existing rows. New entries into `event_push_actions`
and `event_push_actions_staging` will get the proper thread ID.
`receipts_linearized` and `receipts_graph` also gain a `thread_id` column, which is similar,
except `NULL` is a special value meaning the receipt is "unthreaded".
See MSC3771 and MSC3773 for where this data will be useful.
Most of the time this function is heavily cached, but when that isn't
the case fetching the counts room by room slows down push delivery on
users with many (thousands) of rooms.

This avoids doing work that will never be used (since the
resulting unread counts will never be sent in a /sync
response).
The negative of doing this is that unread counts will be
incorrect when the feature is initially enabled.
Broke by #13522
It looks like we have some rules in the DB with a priority class less
than 0 that don't override the base rules. Before these were just
dropped, but #13522 made that a hard error.
This improves load times for push rules:
| Version | Time per user | Time for 1k users |
| -------------------- | ------------- | ----------------- |
| Before | 138 µs | 138ms |
| Now (with custom) | 2.11 µs | 2.11ms |
| Now (without custom) | 49.7 ns | 0.05 ms |
This therefore has a large impact on send times for rooms
with large numbers of local users in the room.
Fixes#11887 hopefully.
The core change here is that `event_push_summary` now holds a summary of counts up until a much more recent point, meaning that the range of rows we need to count in `event_push_actions` is much smaller.
This needs two major changes:
1. When we get a receipt we need to recalculate `event_push_summary` rather than just delete it
2. The logic for deleting `event_push_actions` is now divorced from calculating `event_push_summary`.
In future it would be good to calculate `event_push_summary` while we persist a new event (it should just be a case of adding one to the relevant rows in `event_push_summary`), as that will further simplify the get counts logic and remove the need for us to periodically update `event_push_summary` in a background job.
This simplifies the access token verification logic by removing the `rights`
parameter which was only ever used for the unsubscribe link in email
notifications. The latter has been moved under the `/_synapse` namespace,
since it is not a standard API.
This also makes the email verification link more secure, by embedding the
app_id and pushkey in the macaroon and verifying it. This prevents the user
from tampering the query parameters of that unsubscribe link.
Macaroon generation is refactored:
- Centralised all macaroon generation and verification logic to the
`MacaroonGenerator`
- Moved to `synapse.utils`
- Changed the constructor to require only a `Clock`, hostname, and a secret key
(instead of a full `Homeserver`).
- Added tests for all methods.
