Fixup for https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/3017
This reverts 1cd82cf068 and also multiplies results by `1024`
so as to pass bytes to Synapse, not KB (as done before).
1cd82cf068 was correctly documenting what we were doing (passing KB values),
but that's incorrect.
Synapse's Config Conventions
(https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#config-conventions)
are supposed to clear it up, but they don't currently state what happens when you pass a plain number (without a unit suffix).
Thankfully, the source code tells us:
bc1db16086/synapse/config/_base.py (L181-L206)
> If an integer is provided it is treated as bytes and is unchanged.
>
> String byte sizes can have a suffix of ...
> No suffix is understood as a plain byte count.
We were previously passing strings, but that has been improved in 3d73ec887a.
Regardless, non-suffixed values seem to be treated as bytes by Synapse,
so this patch changes the variables to use bytes.
Moreover, we're moving from `matrix_synapse_memtotal_kb` to
`matrix_synapse_cache_size_calculations_memtotal_bytes` as working with
the base unit everywhere is preferrable.
Here, we also introduce 2 new variables to allow for the caps to be
tweaked:
- `matrix_synapse_cache_size_calculations_max_cache_memory_usage_cap_bytes`
- `matrix_synapse_cache_size_calculations_target_cache_memory_usage_cap_bytes`
* Modify Synapse Cache Factor to use Auto Tune
Synapse has the ability to as it calls in its config auto tune caches.
This ability lets us set very high cache factors and then instead limit our resource use.
Defaults for this commit are 1/10th of what Element apparently runs for EMS stuff and matrix.org on Cache Factor and upstream documentation defaults for auto tune.
* Add vars to Synapse main.yml to control cache related config
This commit adds various cache related vars to main.yml for Synapse.
Some are auto tune and some are just adding explicit ways to control upstream vars.
* Updated Auto Tune figures
Autotuned figures have been bumped in consultation with other community members as to a reasonable level. Please note these defaults are more on the one of each workers side than they are on the monolith Side.
* Fix YML Error
The playbook is not happy with the previous state of this patch so this commit hopefully fixes it
* Add to_json to various Synapse tuning related configs
* Fix incorrect indication in homeserver.yaml.j2
* Minor cleanups
* Synapse Cache Autotuning Documentation
* Upgrade Synapse Cache Autotune to auto configure memory use
* Update Synapse Tuning docs to reflect automatic memory use configuration
* Fix Linting errors in synapses main.yml
* Rename variables for consistency (matrix_synapse_caches_autotuning_* -> matrix_synapse_cache_autotuning_*)
* Remove FIX ME comment about Synapse's `cache_autotuning`
`docs/maintenance-synapse.md` and `roles/custom/matrix-synapse/defaults/main.yml`
already contains documentation about these variables and the default values we set.
* Improve "Tuning caches and cache autotuning" documentation for Synapse
* Announce larger Synapse caches and cache auto-tuning

This changes the behavior of
`matrix_playbook_migration_matrix_nginx_proxy_uninstallation_enabled`
and is against what we initially described in the changelog entry,
but I've discovered some problems when the `matrix-nginx-proxy` service
and container remain running. They need to go.
Issues and Pull Requests were not migrated to the new
organization/repository, so `matrix-org/synapse/pull` and
`matrix-org/synapse/issues` references were kept as-is.
`matrix-org/synapse-s3-storage-provider` references were also kept,
as that module still continues living under the `matrix-org` organization.
This patch mainly aims to change documentation-related things, not actual
usage in full yet. For polish that, another more comprehensive patch is coming later.
Hopefully, this makes it clearer that it's not just "public rooms"
that will now be exposed,
but rather "public rooms which are also published to the room directory".
This brings the values up-to-date as of the latest indexing run done
today. Due to a bug, the previous values were somewhat off.
The new numbers are different and actually demonstrate that the situation is
much worse than initially imagined.
Draupnir moved its repo on github from the namespace of its maintainer Gnuxie to a newly created Github Organisation the-draupnir-project and this commit reflects this.
The variable was necessary when multiple playbooks could have
potentially tried to manage a shared `devture-traefik.serivce` systemd service
and shared `/devture-traefik` directory.
Since adcc6d9723, we use our own `/matrix/traefik`
(`matrix-traefik.service`) installation and no conflicts can arise.
It's safe to always enable the role, just like we do with all the other roles.
The newly extracted role also has native Traefik support,
so we no longer need to rely on `matrix-nginx-proxy` for
reverse-proxying to Ntfy.
The new role uses port `80` inside the container (not `8080`, like
before), because that's the default assumption of the officially
published container image. Using a custom port (like `8080`), means the
default healthcheck command (which hardcodes port `80`) doesn't work.
Instead of fiddling to override the healthcheck command, we've decided
to stick to the default port instead. This only affects the
inside-the-container port, not any external ports.
The new role also supports adding the network ranges of the container's
multiple additional networks as "exempt hosts". Previously, only one
network's address range was added to "exempt hosts".
This helps large deployments which need to open up thousands of ports
(matrix_coturn_turn_udp_min_port, matrix_coturn_turn_udp_min_port)
On a test VM, opening 1k ports takes 17 seconds for Docker to "publish"
all of these ports (setting up forwarding rules with the firewall, etc),
so service startup and shutdown take a long amount of time.
If host-networking is used, there's no need to open any ports at all
and startup/shutdown can be quick.
This role is usable on its own and it's not tied to Matrix, so
extracting it out into an independent role that we install via
ansible-galaxy makes sense.
This also fixes the confusion from the other day, where
`matrix_postgres_*` had to be renamed to `devture_postgres_*`
(unless it was about `matrix_postgres_backup_*`).
We now can safely say that ALL `matrix_postgres_*` variables need to be
renamed.

As stream writer workers are also powered by the `generic_worker`
Synapse app, this necessitated that we provide means for distinguishing
between them and regular `generic_workers`.
I've also taken the time to optimize nginx configuration generation
(more Jinja2 macro usage, less duplication).
Worker names have also changed.
Workers are now named sequentially like this:
- `matrix-synapse-worker-0-generic`
- `matrix-synapse-worker-1-stream-writer-typing`
- `matrix-synapse-worker-2-pusher`
instead of `matrix-synapse-worker_generic_worker-18111` (indexed with a
port number).
People who modify `matrix_synapse_workers_enabled_list` directly will
need to adjust their configuration.
