## The big move to all-on-Postgres (potentially dangerous)
**TLDR**: all your bridges (and other services) will likely be auto-migrated from SQLite/nedb to Postgres, hopefully without trouble. You can opt-out (see how below), if too worried about breakage.
Until now, we've only used Postgres as a database for Synapse. All other services (bridges, bots, etc.) were kept simple and used a file-based database (SQLite or nedb).
Since [this huge pull request](https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/740), **all of our services now use Postgres by default**. Thanks to [Johanna Dorothea Reichmann](https://github.com/jdreichmann) for starting the work on it and for providing great input!
Moving all services to Postgres brings a few **benefits** to us:
- **improved performance**
- **improved compatibility**. Most bridges are deprecating SQLite/nedb support or offer less features when not on Postgres.
- **easier backups**. It's still some effort to take a proper backup (Postgres dump + various files, keys), but a Postgres dump now takes you much further.
- we're now **more prepared to introduce other services** that need a Postgres database - [Dendrite](https://github.com/matrix-org/dendrite), the [mautrix-signal](https://github.com/tulir/mautrix-signal) bridge (existing [pull request](https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/686)), etc.
### Key takeway
- existing installations that use an [external Postgres](https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/master/docs/configuring-playbook-external-postgres.md) server should be unaffected (they remain on SQLite/nedb for all services, except Synapse)
- for existing installations which use our integrated Postgres database server (`matrix-postgres`, which is the default), **we automatically migrate data** from SQLite/nedb to Postgres and **archive the database files** (`something.db` -> `something.db.backup`), so you can restore them if you need to go back (see how below).
### Opting-out of the Postgres migration
This is a **very large and somewhat untested change** (potentially dangerous), so **if you're not feeling confident/experimental, opt-out** of it for now. Still, it's the new default and what we (and various bridges) will focus on going forward, so don't stick to old ways for too long.
You can remain on SQLite/nedb (at least for now) by adding a variable like this to your `vars.yml` file for each service you use: `matrix_COMPONENT_database_engine: sqlite` (e.g. `matrix_mautrix_facebook_database_engine: sqlite`).
Some services (like `appservice-irc` and `appservice-slack`) don't use SQLite, so use `nedb`, instead of `sqlite` for them.
### Going back to SQLite/nedb if things went wrong
If you went with the Postgres migration and it went badly for you (some bridge not working as expected or not working at all), do this:
- stop all services (`ansible-playbook -i inventory/hosts setup.yml --tags=stop`)
- SSH into the server and rename the old database files (`something.db.backup` -> `something.db`). Example: `mv /matrix/mautrix-facebook/data/mautrix-facebook.db.backup /matrix/mautrix-facebook/data/mautrix-facebook.db`
- switch the affected service back to SQLite (e.g. `matrix_mautrix_facebook_database_engine: sqlite`). Some services (like `appservice-irc` and `appservice-slack`) don't use SQLite, so use `nedb`, instead of `sqlite` for them.
- re-run the playbook (`ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`)

## synapse-janitor support removed
We've removed support for the unmaintained [synapse-janitor](https://github.com/xwiki-labs/synapse_scripts) script. There's been past reports of it corrupting the Synapse database. Since there hasn't been any new development on it and it doesn't seem too useful nowadays, there's no point in including it in the playbook.
If you need to clean up or compact your database, consider using the Synapse Admin APIs directly. See our [Synapse maintenance](docs/maintenance-synapse.md) and [Postgres maintenance](docs/maintenance-postgres.md) documentation pages for more details.
## Docker 20.10 is here
(No need to do anything special in relation to this. Just something to keep in mind)
Docker 20.10 got released recently and your server will likely get it the next time you update.
This is the first major Docker update in a long time and it packs a lot of changes.
Some of them introduced some breakage for us initially (see [here](https://github.com/spantaleev/matrix-docker-ansible-deploy/commit/d08b27784f222effcbce2abf924bf07bbe0893be) and [here](https://github.com/spantaleev/matrix-docker-ansible-deploy/commit/7593d969e316cc0144bce378a5be58c76c2c37ee)), but it should be all good now.
# 2020-12-08
## openid APIs exposed by default on the federation port when federation disabled
We've changed some defaults. People running with our default configuration (federation enabled), are not affected at all.
If you are running an unfederated server (`matrix_synapse_federation_enabled: false`), this may be of interest to you.
When federation is disabled, but ma1sd or Dimension are enabled, we'll now expose the `openid` APIs on the federation port.
These APIs are necessary for some ma1sd features to work. If you'd like to prevent this, you can: `matrix_synapse_federation_port_openid_resource_required: false`.
# 2020-11-27
## Recent Jitsi updates may require configuration changes
We've recently [updated from Jitsi build 4857 to build 5142](https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/719), which brings a lot of configuration changes.
**If you use our default Jitsi settings, you won't have to do anything.**
People who have [fine-tuned Jitsi](docs/configuring-playbook-jitsi.md#optional-fine-tune-jitsi) may find that some options got renamed now, others are gone and yet others still need to be defined in another way.
The next time you run the playbook [installation](docs/installing.md) command, our validation logic will tell you if you're using some variables like that and will recommend a migration path for each one.
Additionally, we've recently disabled transcriptions (`matrix_jitsi_enable_transcriptions: false`) and recording (`matrix_jitsi_enable_recording: false`) by default. These features did not work anyway, because we don't install the required dependencies for them (Jigasi and Jibri, respectively). If you've been somehow pointing your Jitsi installation to some manually installed Jigasi/Jibri service, you may need to toggle these flags back to enabled to have transcriptions and recordings working.

## Breaking change matrix-sms-bridge
Because of many problems using gammu as SMS provider, matrix-sms-bridge now uses (https://github.com/RebekkaMa/android-sms-gateway-server) by default. See (the docs)[./docs/configuring-playbook-bridge-matrix-bridge-sms.md] which new vars you need to add.
If you are using this playbook to deploy matrix-sms-bridge and still really want to use gammu as SMS provider, we could possibly add support for both android-sms-gateway-server and gammu.
# 2020-11-13
## Breaking change matrix-sms-bridge
The new version of [matrix-sms-bridge](https://github.com/benkuly/matrix-sms-bridge) changed its database from neo4j to h2. You need to sync the bridge at the first start. Note that this only will sync rooms where the @smsbot:yourServer is member. For rooms without @smsbot:yourServer you need to kick and invite the telephone number **or** invite @smsbot:yourServer.
1. Add the following to your `vars.yml` file: `matrix_sms_bridge_container_extra_arguments=['--env SPRING_PROFILES_ACTIVE=initialsync']`
2. Login to your host shell and remove old systemd file from your host: `rm /etc/systemd/system/matrix-sms-bridge-database.service`
2. Run `ansible-playbook -i inventory/hosts setup.yml --tags=setup-matrix-sms-bridge,start`
3. Login to your host shell and check the logs with `journalctl -u matrix-sms-bridge` until the sync finished.
4. Remove the var from the first step.
5. Run `ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`.

## Dynamic DNS support
Thanks to [Scott Crossen](https://github.com/scottcrossen), the playbook can now manage Dynamic DNS for you using [ddclient](https://ddclient.net/).
To learn more, follow our [Dynamic DNS docs page](docs/configuring-playbook-dynamic-dns.md).
# 2020-10-28
## (Compatibility Break) https://matrix.DOMAIN/ now redirects to https://element.DOMAIN/
Until now, we used to serve a static page coming from Synapse at `https://matrix.DOMAIN/`. This page was not very useful to anyone.
Since `matrix.DOMAIN` may be accessed by regular users in certain conditions, it's probably better to redirect them to a better place (e.g. to the [Element](docs/configuring-playbook-client-element.md) client).
If Element is installed (`matrix_client_element_enabled: true`, which it is by default), we now redirect people to it, instead of showing them a Synapse static page.
If you'd like to control where the redirect goes, use the `matrix_nginx_proxy_proxy_matrix_client_redirect_root_uri_to_domain` variable.
To restore the old behavior of not redirecting anywhere and serving the Synapse static page, set it to an empty value (`matrix_nginx_proxy_proxy_matrix_client_redirect_root_uri_to_domain: ""`).
# 2020-10-26
## (Compatibility Break) /_synapse/admin is no longer publicly exposed by default
We used to expose the Synapse Admin APIs publicly (at `https://matrix.DOMAIN/_synapse/admin`).
These APIs require authentication with a valid access token, so it's not that big a deal to expose them.
However, following [official Synapse's reverse-proxying recommendations](https://github.com/matrix-org/synapse/blob/master/docs/reverse_proxy.md#synapse-administration-endpoints), we're no longer exposing `/_synapse/admin` by default.
If you'd like to restore restore the old behavior and expose `/_synapse/admin` publicly, you can use the following configuration (in your `vars.yml`):

First you need to ensure, that the bridge has unix read and write rights to your modem. On debian based distributions there is nothing to do. On others distributions you either add a group `dialout` to your host and assign it to your modem or you give the matrix user or group access to your modem.
**The bridge uses [android-sms-gateway-server](https://github.com/RebekkaMa/android-sms-gateway-server). You need to configure it first.**
**[Dimension](https://dimension.t2bot.io) can only be installed after Matrix services are installed and running.**
If you're just installing Matrix services for the first time, please continue with the [Configuration](configuring-playbook.md) / [Installation](installing.md) flow and come back here later.
**Note**: enabling Dimension, means that the `openid` API endpoints will be exposed on the Matrix Federation port (usually `8448`), even if [federation](configuring-playbook-federation.md) is disabled. It's something to be aware of, especially in terms of firewall whitelisting (make sure port `8448` is accessible).
## Prerequisites
This playbook now supports running [Dimension](https://dimension.t2bot.io) in both a federated and an [unfederated](https://github.com/turt2live/matrix-dimension/blob/master/docs/unfederated.md) environment. This is handled automatically based on the value of `matrix_synapse_federation_enabled`.
With that, your server's users will only be able to talk among themselves, but not to anyone who is on another server.
**Disabling federation does not necessarily disable the federation port** (`8448`). Services like [Dimension](configuring-playbook-dimension.md) and [ma1sd](configuring-playbook-ma1sd.md) normally rely on `openid` APIs exposed on that port. Even if you disable federation and only if necessary, we may still be exposing the federation port and serving the `openid` APIs there. To override this and completely disable Synapse's federation port use:
```yaml
# This stops the federation port on the Synapse side (normally `matrix-synapse:8048` on the container network).
matrix_synapse_federation_port_enabled: false
# This removes the `8448` virtual host from the matrix-nginx-proxy reverse-proxy server.

**Note**: If you have some trouble with your installation configuration, you can just [re-run the playbook](installing.md) and it will try to set things up again. You don't need to uninstall and install fresh.
**Warnings**:
However, if you've installed this on some server where you have other stuff you wish to preserve, and now want get rid of Matrix, it's enough to do these:
- If your server federates with others, make sure to **leave any federated rooms before nuking your Matrix server's data**. Otherwise, the next time you set up a Matrix server for this domain (regardless of the installation method you use), you'll encounter trouble federating.
- ensure all Matrix services are stopped (`systemctl stop 'matrix*'`)
- If you have some trouble with your installation, you can just [re-run the playbook](installing.md) and it will try to set things up again. **Uninstalling and then installing anew rarely solves anything**.
- delete the Matrix-related systemd .service files (`rm -f /etc/systemd/system/matrix*`) and reload systemd (`systemctl daemon-reload`)
-----------------
## Uninstalling using a script
Installing places a `/usr/local/bin/matrix-remove-all` script on the server.
You can run it to to have it uninstall things for you automatically (see below). **Use with caution!**
## Uninstalling manually
If you prefer to uninstall manually, run these commands (most are meant to be executed on the Matrix server itself):
- ensure all Matrix services are stopped: `ansible-playbook -i inventory/hosts setup.yml --tags=stop` (if you can't get Ansible working to run this command, you can run `systemctl stop 'matrix*'` manually on the server)
- delete the Matrix-related systemd `.service` files (`rm -f /etc/systemd/system/matrix*.service`) and reload systemd (`systemctl daemon-reload`)
- delete all Matrix-related cronjobs (`rm -f /etc/cron.d/matrix*`)
- delete some helper scripts (`rm -f /usr/local/bin/matrix*`)
- delete some cached Docker images (or just delete them all: `docker rmi $(docker images -aq)`)
- delete some cached Docker images (`docker system prune -a`) or just delete them all (`docker rmi $(docker images -aq)`)
- delete the Docker network: `docker network rm matrix`
- delete the Docker network: `docker network rm matrix` (might have been deleted already if you ran the `docker system prune` command)
- uninstall Docker itself, if necessary
- delete the `/matrix` directory (`rm -rf /matrix`)
The script `/usr/local/bin/matrix-remove-all` performs all these steps (**use with caution!**).
