If things like the signing key file are missing, let's just try to generate them on startup.

Again, this is useful for k8s-like deployments where we just want to generate keys on the first run.

This is a very neat change! In principle this opens up the possibility of sidestepping the dpkg-statoverride for /{etc,var/{lib,log}}/matrix-synapse' completely, by having ConfigurationDirectory=, StateDirectory=andLogsDirectory=` in the service file, so that they too are created before synapse starts for the first time.

I don't entirely follow this. This change is not about creating files before Synapse starts; rather it is about creating them after it first starts.

Sorry if I was obtuse. systemd has unit file options for services ConfigurationDirectory=, StateDirectory=, LogsDirectory= (and a few more). They are created (or recreated for those that are not persisted) on start of the service. So by adding these options to the shipped service file, combined with the change in this PR, shipping a default config file by default should no longer be necessary, as it will be created on first start (something that Debian does by default on install anyway). This also omits creating the synapse-specific directories in the postinst script.

I'll open a PR to discuss this once this one lands.

Synapse 1.67.0 (2022-09-13)
===========================

This release removes using the deprecated direct TCP replication configuration
for workers. Server admins should use Redis instead. See the [upgrade
notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).

The minimum version of `poetry` supported for managing source checkouts is now
1.2.0.

**Notice:** from the next major release (1.68.0) installing Synapse from a source
checkout will require a recent Rust compiler. Those using packages or
`pip install matrix-synapse` will not be affected. See the [upgrade
notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).

**Notice:** from the next major release (1.68.0), running Synapse with a SQLite
database will require SQLite version 3.27.0 or higher. (The [current minimum
 version is SQLite 3.22.0](https://github.com/matrix-org/synapse/blob/release-v1.67/synapse/storage/engines/sqlite.py#L69-L78).)
See [matrix-org#12983](matrix-org#12983) and the [upgrade notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670) for more details.

No significant changes since 1.67.0rc1.

Synapse 1.67.0rc1 (2022-09-06)
==============================

Features
--------

- Support setting the registration shared secret in a file, via a new `registration_shared_secret_path` configuration option. ([\matrix-org#13614](matrix-org#13614))
- Change the default startup behaviour so that any missing "additional" configuration files (signing key, etc) are generated automatically. ([\matrix-org#13615](matrix-org#13615))
- Improve performance of sending messages in rooms with thousands of local users. ([\matrix-org#13634](matrix-org#13634))

Bugfixes
--------

- Fix a bug introduced in Synapse 1.13 where the [List Rooms admin API](https://matrix-org.github.io/synapse/develop/admin_api/rooms.html#list-room-api) would return integers instead of booleans for the `federatable` and `public` fields when using a Sqlite database. ([\matrix-org#13509](matrix-org#13509))
- Fix bug that user cannot `/forget` rooms after the last member has left the room. ([\matrix-org#13546](matrix-org#13546))
- Faster Room Joins: fix `/make_knock` blocking indefinitely when the room in question is a partial-stated room. ([\matrix-org#13583](matrix-org#13583))
- Fix loading the current stream position behind the actual position. ([\matrix-org#13585](matrix-org#13585))
- Fix a longstanding bug in `register_new_matrix_user` which meant it was always necessary to explicitly give a server URL. ([\matrix-org#13616](matrix-org#13616))
- Fix the running of [MSC1763](matrix-org/matrix-spec-proposals#1763) retention purge_jobs in deployments with background jobs running on a worker by forcing them back onto the main worker. Contributed by Brad @ Beeper. ([\matrix-org#13632](matrix-org#13632))
- Fix a long-standing bug that downloaded media for URL previews was not deleted while database background updates were running. ([\matrix-org#13657](matrix-org#13657))
- Fix [MSC3030](matrix-org/matrix-spec-proposals#3030) `/timestamp_to_event` endpoint to return the correct next event when the events have the same timestamp. ([\matrix-org#13658](matrix-org#13658))
- Fix bug where we wedge media plugins if clients disconnect early. Introduced in v1.22.0. ([\matrix-org#13660](matrix-org#13660))
- Fix a long-standing bug which meant that keys for unwhitelisted servers were not returned by `/_matrix/key/v2/query`. ([\matrix-org#13683](matrix-org#13683))
- Fix a bug introduced in Synapse v1.20.0 that would cause the unstable unread counts from [MSC2654](matrix-org/matrix-spec-proposals#2654) to be calculated even if the feature is disabled. ([\matrix-org#13694](matrix-org#13694))

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

- Update docker image to use a stable version of poetry. ([\matrix-org#13688](matrix-org#13688))

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

- Improve the description of the ["chain cover index"](https://matrix-org.github.io/synapse/latest/auth_chain_difference_algorithm.html) used internally by Synapse. ([\matrix-org#13602](matrix-org#13602))
- Document how ["monthly active users"](https://matrix-org.github.io/synapse/latest/usage/administration/monthly_active_users.html) is calculated and used. ([\matrix-org#13617](matrix-org#13617))
- Improve documentation around user registration. ([\matrix-org#13640](matrix-org#13640))
- Remove documentation of legacy `frontend_proxy` worker app. ([\matrix-org#13645](matrix-org#13645))
- Clarify documentation that HTTP replication traffic can be protected with a shared secret. ([\matrix-org#13656](matrix-org#13656))

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

- Drop support for calling `/_matrix/client/v3/rooms/{roomId}/invite` without an `id_access_token`, which was not permitted by the spec. Contributed by @Vetchu. ([\matrix-org#13241](matrix-org#13241))
- Remove redundant `_get_joined_users_from_context` cache. Contributed by Nick @ Beeper (@Fizzadar). ([\matrix-org#13569](matrix-org#13569))
