Part of #11106. The Prometheus recording rules are updated to use the futureproof names. This is compatible with both 'legacy' Synapse installations and experimental 'non-legacy' Synapse installations.

The Prometheus v1 recording rules are removed since Prometheus v1 is very old and we don't update that file anymore; it doesn't seem worth keeping.

(N.B. I also fix a metric that I forgot to rename in #13540)

Daunting but looks sane!

Have you had a chance to test this?

This is compatible with both 'legacy' Synapse installations and experimental 'non-legacy' Synapse installations.

Because both configurations report the futureproof metrics?

Any way to check if we've missed any others? I guess grep for "synapse_.*:.*"?

Should have thought of that; suppose I never really twigged that they all have a convenient synapse_ prefix that makes them greppable instead of 'string with colon' in :-)

Found another pair of sneaky ones ...

I'm just guessing here!!

Could also grep for something like Counter\(\n?.*".*: and Gauge\(\n?.*".*: if you can get the multiline regex stuff working

Conventionally we definitely are meant to use an easily-recognised prefix like synapse_. I don't think even we would ignore that...

  • Not yet, I will do so before merging.

yep, exactly, we have been doing so for a long time :)

Synapse 1.68.0 (2022-09-27)
===========================

Please note that Synapse will now refuse to start if configured to use a version of SQLite older than 3.27.

In addition, please note that installing Synapse from a source checkout now requires a recent Rust compiler.
Those using packages will not be affected. On most platforms, installing with `pip install matrix-synapse` will not be affected.
See the [upgrade notes](https://matrix-org.github.io/synapse/v1.68/upgrade.html#upgrading-to-v1680).

Bugfixes
--------

- Fix packaging to include `Cargo.lock` in `sdist`. ([\matrix-org#13909](matrix-org#13909))

Synapse 1.68.0rc2 (2022-09-23)
==============================

Bugfixes
--------

- Fix building from packaged sdist. Broken in v1.68.0rc1. ([\matrix-org#13866](matrix-org#13866))

Synapse 1.68.0rc1 (2022-09-20)
==============================

- Keep track of when we fail to process a pulled event over federation so we can intelligently back off in the future. ([\matrix-org#13589](matrix-org#13589), [\matrix-org#13814](matrix-org#13814))
- Add an [admin API endpoint to fetch messages within a particular window of time](https://matrix-org.github.io/synapse/v1.68/admin_api/rooms.html#room-messages-api). ([\matrix-org#13672](matrix-org#13672))
- Add an [admin API endpoint to find a user based on their external ID in an auth provider](https://matrix-org.github.io/synapse/v1.68/admin_api/user_admin_api.html#find-a-user-based-on-their-id-in-an-auth-provider). ([\matrix-org#13810](matrix-org#13810))
- Cancel the processing of key query requests when they time out. ([\matrix-org#13680](matrix-org#13680))

([\matrix-org#13687](matrix-org#13687), [\matrix-org#13736](matrix-org#13736))

Bugfixes
--------

- Fix a bug introduced in Synapse 1.41.0 where the `/hierarchy` API returned non-standard information (a `room_id` field under each entry in `children_state`). ([\matrix-org#13506](matrix-org#13506))
- Fix a long-standing bug where previously rejected events could end up in room state because they pass auth checks given the current state of the room. ([\matrix-org#13723](matrix-org#13723))
- Fix a long-standing bug where Synapse fails to start if a signing key file contains an empty line. ([\matrix-org#13738](matrix-org#13738))
- Fix a long-standing bug where Synapse would fail to handle malformed user IDs or room aliases gracefully in certain cases. ([\matrix-org#13746](matrix-org#13746))
- Fix a long-standing bug where device lists would remain cached when remote users left and rejoined the last room shared with the local homeserver. ([\matrix-org#13749](matrix-org#13749), [\matrix-org#13826](matrix-org#13826))
- Fix a long-standing bug that could cause stale caches in some rare cases on the first startup of Synapse with replication. ([\matrix-org#13766](matrix-org#13766))
- Fix a long-standing spec compliance bug where Synapse would accept a trailing slash on the end of `/get_missing_events` federation requests. ([\matrix-org#13789](matrix-org#13789))
- Delete associated data from `event_failed_pull_attempts`, `insertion_events`, `insertion_event_extremities`, `insertion_event_extremities`, `insertion_event_extremities` when purging the room. ([\matrix-org#13825](matrix-org#13825))

Improved Documentation
----------------------

- Note that `libpq` is required on ARM-based Macs. ([\matrix-org#13480](matrix-org#13480))
- Fix a mistake in the config manual introduced in Synapse 1.22.0: the `event_cache_size` _is_ scaled by `caches.global_factor`. ([\matrix-org#13726](matrix-org#13726))
- Fix a typo in the documentation for the login ratelimiting configuration. ([\matrix-org#13727](matrix-org#13727))
- Define Synapse's compatability policy for SQLite versions. ([\matrix-org#13728](matrix-org#13728))
- Add docs for the common fix of deleting the `matrix_synapse.egg-info/` directory for fixing Python dependency problems. ([\matrix-org#13785](matrix-org#13785))

Deprecations and Removals
-------------------------

- Synapse will now refuse to start if configured to use SQLite < 3.27. ([\matrix-org#13760](matrix-org#13760))
- Don't include redundant `prev_state` in new events. Contributed by Denis Kariakin (@dakariakin). ([\matrix-org#13791](matrix-org#13791))

Internal Changes
----------------

- Add a stub Rust crate. ([\matrix-org#12595](matrix-org#12595), [\matrix-org#13734](matrix-org#13734), [\matrix-org#13735](matrix-org#13735), [\matrix-org#13743](matrix-org#13743), [\matrix-org#13763](matrix-org#13763), [\matrix-org#13769](matrix-org#13769), [\matrix-org#13778](matrix-org#13778))
- Bump the minimum dependency of `matrix_common` to 1.3.0 to make use of the `MXCUri` class. Use `MXCUri` to simplify media retention test code. ([\matrix-org#13162](matrix-org#13162))
- Add and populate the `event_stream_ordering` column on the `receipts` table for future optimisation of push action processing. Contributed by Nick @ Beeper (@Fizzadar). ([\matrix-org#13703](matrix-org#13703))

- Update the docstrings for `get_users_in_room` and `get_current_hosts_in_room` to explain the impact of partial state. ([\matrix-org#13750](matrix-org#13750))

- Deduplicate `is_server_notices_room`. ([\matrix-org#13780](matrix-org#13780))
- Simplify the dependency DAG in the tests workflow. ([\matrix-org#13784](matrix-org#13784))
- Remove an old, incorrect migration file. ([\matrix-org#13788](matrix-org#13788))
