keylen seems to be a thing that is frequently incorrectly set, and we don't really need it.

The only time it was used was to figure out if we had removed a subtree in del_multi, which we can do better by changing TreeCache.pop to return a different type (TreeCacheNode).

Commits should be independently reviewable.

@richvdh
Make del_multi independent of keylen
9d7e050 
Changes the way TreeCache works, so that it's easier to tell when you have
removed a subtree or a leaf node from the tree - hence `del_multi` doesn't need
to care about `keylen`.
@richvdh
Remove redundant keylen param on LruCache
175c8ae 
This is no longer required.

I've replaced setdefault with separate get and set to avoid making lots of redundant TreeCacheNode objects.

Update chat/matrix-synapses to 1.35.1
7f7c8d5 
Synapse 1.35.1 (2021-06-03)
===========================

Bugfixes
--------

- Fix a bug introduced in v1.35.0 where invite-only rooms would be shown to all users in a space, regardless of if the user had access to it. ([\#10109](matrix-org/synapse#10109))


Synapse 1.35.0 (2021-06-01)
===========================

Note that [the tag](https://github.com/matrix-org/synapse/releases/tag/v1.35.0rc3) and [docker images](https://hub.docker.com/layers/matrixdotorg/synapse/v1.35.0rc3/images/sha256-34ccc87bd99a17e2cbc0902e678b5937d16bdc1991ead097eee6096481ecf2c4?context=explore) for `v1.35.0rc3` were incorrectly built. If you are experiencing issues with either, it is recommended to upgrade to the equivalent tag or docker image for the `v1.35.0` release.

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

- The core Synapse development team plan to drop support for the [unstable API of MSC2858](https://github.com/matrix-org/matrix-doc/blob/master/proposals/2858-Multiple-SSO-Identity-Providers.md#unstable-prefix), including the undocumented `experimental.msc2858_enabled` config option, in August 2021. Client authors should ensure that their clients are updated to use the stable API (which has been supported since Synapse 1.30) well before that time, to give their users time to upgrade. ([\#10101](matrix-org/synapse#10101))

Bugfixes
--------

- Fixed a bug causing replication requests to fail when receiving a lot of events via federation. Introduced in v1.33.0. ([\#10082](matrix-org/synapse#10082))
- Fix HTTP response size limit to allow joining very large rooms over federation. Introduced in v1.33.0. ([\#10093](matrix-org/synapse#10093))


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

- Log method and path when dropping request due to size limit. ([\#10091](matrix-org/synapse#10091))


Synapse 1.35.0rc2 (2021-05-27)
==============================

Bugfixes
--------

- Fix a bug introduced in v1.35.0rc1 when calling the spaces summary API via a GET request. ([\#10079](matrix-org/synapse#10079))


Synapse 1.35.0rc1 (2021-05-25)
==============================

Features
--------

- Add experimental support to allow a user who could join a restricted room to view it in the spaces summary. ([\#9922](matrix-org/synapse#9922), [\#10007](matrix-org/synapse#10007), [\#10038](matrix-org/synapse#10038))
- Reduce memory usage when joining very large rooms over federation. ([\#9958](matrix-org/synapse#9958))
- Add a configuration option which allows enabling opentracing by user id. ([\#9978](matrix-org/synapse#9978))
- Enable experimental support for [MSC2946](matrix-org/matrix-spec-proposals#2946) (spaces summary API) and [MSC3083](matrix-org/matrix-spec-proposals#3083) (restricted join rules) by default. ([\#10011](matrix-org/synapse#10011))


Bugfixes
--------

- Fix a bug introduced in v1.26.0 which meant that `synapse_port_db` would not correctly initialise some postgres sequences, requiring manual updates afterwards. ([\#9991](matrix-org/synapse#9991))
- Fix `synctl`'s `--no-daemonize` parameter to work correctly with worker processes. ([\#9995](matrix-org/synapse#9995))
- Fix a validation bug introduced in v1.34.0 in the ordering of spaces in the space summary API. ([\#10002](matrix-org/synapse#10002))
- Fixed deletion of new presence stream states from database. ([\#10014](matrix-org/synapse#10014), [\#10033](matrix-org/synapse#10033))
- Fixed a bug with very high resolution image uploads throwing internal server errors. ([\#10029](matrix-org/synapse#10029))


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

- Fix bug introduced in Synapse 1.33.0 which caused a `Permission denied: '/homeserver.log'` error when starting Synapse with the generated log configuration. Contributed by Sergio Miguéns Iglesias. ([\#10045](matrix-org/synapse#10045))


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

- Add hardened systemd files as proposed in [#9760](matrix-org/synapse#9760) and added them to `contrib/`. Change the docs to reflect the presence of these files. ([\#9803](matrix-org/synapse#9803))
- Clarify documentation around SSO mapping providers generating unique IDs and localparts. ([\#9980](matrix-org/synapse#9980))
- Updates to the PostgreSQL documentation (`postgres.md`). ([\#9988](matrix-org/synapse#9988), [\#9989](matrix-org/synapse#9989))
- Fix broken link in user directory documentation. Contributed by @junquera. ([\#10016](matrix-org/synapse#10016))
- Add missing room state entry to the table of contents of room admin API. ([\#10043](matrix-org/synapse#10043))


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

- Removed support for the deprecated `tls_fingerprints` configuration setting. Contributed by Jerin J Titus. ([\#9280](matrix-org/synapse#9280))


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

- Allow sending full presence to users via workers other than the one that called `ModuleApi.send_local_online_presence_to`. ([\#9823](matrix-org/synapse#9823))
- Update comments in the space summary handler. ([\#9974](matrix-org/synapse#9974))
- Minor enhancements to the `@cachedList` descriptor. ([\#9975](matrix-org/synapse#9975))
- Split multipart email sending into a dedicated handler. ([\#9977](matrix-org/synapse#9977))
- Run `black` on files in the `scripts` directory. ([\#9981](matrix-org/synapse#9981))
- Add missing type hints to `synapse.util` module. ([\#9982](matrix-org/synapse#9982))
- Simplify a few helper functions. ([\#9984](matrix-org/synapse#9984), [\#9985](matrix-org/synapse#9985), [\#9986](matrix-org/synapse#9986))
- Remove unnecessary property from SQLBaseStore. ([\#9987](matrix-org/synapse#9987))
- Remove `keylen` param on `LruCache`. ([\#9993](matrix-org/synapse#9993))
- Update the Grafana dashboard in `contrib/`. ([\#10001](matrix-org/synapse#10001))
- Add a batching queue implementation. ([\#10017](matrix-org/synapse#10017))
- Reduce memory usage when verifying signatures on large numbers of events at once. ([\#10018](matrix-org/synapse#10018))
- Properly invalidate caches for destination retry timings every (instead of expiring entries every 5 minutes). ([\#10036](matrix-org/synapse#10036))
- Fix running complement tests with Synapse workers. ([\#10039](matrix-org/synapse#10039))
- Fix typo in `get_state_ids_for_event` docstring where the return type was incorrect. ([\#10050](matrix-org/synapse#10050))
