This should save some CPU time.

We might also want to increase the cache size on is_partial_state_room?

Do we want to target the release branch instead?

Also -- I didn't check if other places besides the sync code could use this?

Yes, I've updated that.

I think we want to nuke the 3 first commits of this PR that are unrelated and got pulled from develop.

Update chat/matrix-synapse to 1.76.0
75d0625 
Synapse 1.76.0 (2023-01-31)
===========================

The 1.76 release is the first to enable faster joins ([MSC3706](matrix-org/matrix-spec-proposals#3706) and [MSC3902](matrix-org/matrix-spec-proposals#3902)) by default. Admins can opt-out: see [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.76/docs/upgrade.md#faster-joins-are-enabled-by-default) for more details.

The upgrade from 1.75 to 1.76 changes the account data replication streams in a backwards-incompatible manner. Server operators running a multi-worker deployment should consult [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.76/docs/upgrade.md#changes-to-the-account-data-replication-streams).

Those who are `poetry install`ing from source using our lockfile should ensure their poetry version is 1.3.2 or higher; [see upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.76/docs/upgrade.md#minimum-version-of-poetry-is-now-132).


Notes on faster joins
---------------------

The faster joins project sees the most benefit when joining a room with a large number of members (joined or historical). We expect it to be particularly useful for joining large public rooms like the [Matrix HQ](https://matrix.to/#/#matrix:matrix.org) or [Synapse Admins](https://matrix.to/#/#synapse:matrix.org) rooms.

After a faster join, Synapse considers that room "partially joined". In this state, you should be able to

- read incoming messages;
- see incoming state changes, e.g. room topic changes; and
- send messages, if the room is unencrypted.

Synapse has to spend more effort to complete the join in the background. Once this finishes, you will be able to

- send messages, if the room is in encrypted;
- retrieve room history from before your join, if permitted by the room settings; and
- access the full list of room members.


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

- Describe the ideas and the internal machinery behind faster joins. ([\#14677](matrix-org/synapse#14677))


Synapse 1.76.0rc2 (2023-01-27)
==============================

Bugfixes
--------

- Faster joins: Fix a bug introduced in Synapse 1.69 where device list EDUs could fail to be handled after a restart when a faster join sync is in progress. ([\#14914](matrix-org/synapse#14914))


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

- Faster joins: Improve performance of looking up partial-state status of rooms. ([\#14917](matrix-org/synapse#14917))


Synapse 1.76.0rc1 (2023-01-25)
==============================

Features
--------

- Update the default room version to [v10](https://spec.matrix.org/v1.5/rooms/v10/) ([MSC 3904](matrix-org/matrix-spec-proposals#3904)). Contributed by @FSG-Cat. ([\#14111](matrix-org/synapse#14111))
- Add a `set_displayname()` method to the module API for setting a user's display name. ([\#14629](matrix-org/synapse#14629))
- Add a dedicated listener configuration for `health` endpoint. ([\#14747](matrix-org/synapse#14747))
- Implement support for [MSC3890](matrix-org/matrix-spec-proposals#3890): Remotely silence local notifications. ([\#14775](matrix-org/synapse#14775))
- Implement experimental support for [MSC3930](matrix-org/matrix-spec-proposals#3930): Push rules for ([MSC3381](matrix-org/matrix-spec-proposals#3381)) Polls. ([\#14787](matrix-org/synapse#14787))
- Per [MSC3925](matrix-org/matrix-spec-proposals#3925), bundle the whole of the replacement with any edited events, and optionally inhibit server-side replacement. ([\#14811](matrix-org/synapse#14811))
- Faster joins: always serve a partial join response to servers that request it with the stable query param. ([\#14839](matrix-org/synapse#14839))
- Faster joins: allow non-lazy-loading ("eager") syncs to complete after a partial join by omitting partial state rooms until they become fully stated. ([\#14870](matrix-org/synapse#14870))
- Faster joins: request partial joins by default. Admins can opt-out of this for the time being---see the upgrade notes. ([\#14905](matrix-org/synapse#14905))


Bugfixes
--------

- Add index to improve performance of the `/timestamp_to_event` endpoint used for jumping to a specific date in the timeline of a room. ([\#14799](matrix-org/synapse#14799))
- Fix a long-standing bug where Synapse would exhaust the stack when processing many federation requests where the remote homeserver has disconencted early. ([\#14812](matrix-org/synapse#14812), [\#14842](matrix-org/synapse#14842))
- Fix rare races when using workers. ([\#14820](matrix-org/synapse#14820))
- Fix a bug introduced in Synapse 1.64.0 when using room version 10 with frozen events enabled. ([\#14864](matrix-org/synapse#14864))
- Fix a long-standing bug where the `populate_room_stats` background job could fail on broken rooms. ([\#14873](matrix-org/synapse#14873))
- Faster joins: Fix a bug in worker deployments where the room stats and user directory would not get updated when finishing a fast join until another event is sent or received. ([\#14874](matrix-org/synapse#14874))
- Faster joins: Fix incompatibility with joins into restricted rooms where no local users have the ability to invite. ([\#14882](matrix-org/synapse#14882))
- Fix a regression introduced in Synapse 1.69.0 which can result in database corruption when database migrations are interrupted on sqlite. ([\#14910](matrix-org/synapse#14910))


Updates to the Docker image
---------------------------

- Bump default Python version in the Dockerfile from 3.9 to 3.11. ([\#14875](matrix-org/synapse#14875))


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

- Include `x_forwarded` entry in the HTTP listener example configs and remove the remaining `worker_main_http_uri` entries. ([\#14667](matrix-org/synapse#14667))
- Remove duplicate commands from the Code Style documentation page; point to the Contributing Guide instead. ([\#14773](matrix-org/synapse#14773))
- Add missing documentation for `tag` to `listeners` section. ([\#14803](matrix-org/synapse#14803))
- Updated documentation in configuration manual for `user_directory.search_all_users`. ([\#14818](matrix-org/synapse#14818))
- Add `worker_manhole` to configuration manual. ([\#14824](matrix-org/synapse#14824))
- Fix the example config missing the `id` field in [application service documentation](https://matrix-org.github.io/synapse/latest/application_services.html). ([\#14845](matrix-org/synapse#14845))
- Minor corrections to the logging configuration documentation. ([\#14868](matrix-org/synapse#14868))
- Document the export user data command. Contributed by @thezaidbintariq. ([\#14883](matrix-org/synapse#14883))


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

- Poetry 1.3.2 or higher is now required when `poetry install`ing from source. ([\#14860](matrix-org/synapse#14860))

- Add `cargo fmt` and `cargo clippy` to the lint script. ([\#14822](matrix-org/synapse#14822))
- Drop unused table `presence`. ([\#14825](matrix-org/synapse#14825))
- Merge the two account data and the two device list replication streams. ([\#14826](matrix-org/synapse#14826), [\#14833](matrix-org/synapse#14833))
- Faster joins: use stable identifiers from [MSC3706](matrix-org/matrix-spec-proposals#3706). ([\#14832](matrix-org/synapse#14832), [\#14841](matrix-org/synapse#14841))
- Add a parameter to control whether the federation client performs a partial state join. ([\#14843](matrix-org/synapse#14843))
- Add check to avoid starting duplicate partial state syncs. ([\#14844](matrix-org/synapse#14844))
- Add an early return when handling no-op presence updates. ([\#14855](matrix-org/synapse#14855))

- Always notify replication when a stream advances automatically. ([\#14877](matrix-org/synapse#14877))
- Reduce max time we wait for stream positions. ([\#14881](matrix-org/synapse#14881))
- Faster joins: allow the resync process more time to fetch `/state` ids. ([\#14912](matrix-org/synapse#14912))
- Bump regex from 1.7.0 to 1.7.1. ([\#14848](matrix-org/synapse#14848))
