Subject: [PATCH 01/79] WIP: postgres: create databases for all services

If a service is enabled, a database for it is created in postgres with a uniqque password. The service can then use this database for data storage instead of relying on sqlite.

Subject: [PATCH 03/79] Relocate Postgres additional database creation logic

Moving it above the "uninstalling" set of tasks is better.
Extracting it out to another file at the same time, for readability,
especially given that it will probably have to become more complex in
the future (potentially installing `jq`, etc.)

 different

We'll most likely use one that matches the database name, but
it's better to have it configurable.

Subject: [PATCH 07/79] Determine matrix-postgres IP address without relying on
 jq

To avoid needing to have `jq` installed on the machine, we could:
- try to run jq in a Docker container using some small image providing
that
- better yet, avoid `jq` altogether

Subject: [PATCH 08/79] Prevent weird loop error

> Invalid data passed to 'loop', it requires a list, got this instead: matrix_postgres_additional_databases. Hint: If you passed a list/dict of just one element, try adding wantlist=True to your lookup invocation or use q/query instead of lookup.

Well, or working around it, as I've done in this commit (which seems
more sane than `wantlist=True` stuff).

Subject: [PATCH 09/79] Do not execute additional databases creation code if
 not necessary

The tasks in `create_additional_databases.yml` will likely
ensure `matrix-postgres.service` is started, etc.

If no additional databases are defined, we'd rather not execute that
file and all these tasks that it may do in the future.

Subject: [PATCH 10/79] Do not use the postgresql_user/postgresql_db modules

While these modules are really nice and helpful, we can't use them
for at least 2 reasons:

- for us, Postgres runs in a container on a private Docker network
(`--network=matrix`) without usually being exposed to the host.
These modules execute on the host so they won't be able to reach it.

- these modules require `psycopg2`, so we need to install it before
using it. This might or might not be its own can of worms.

Subject: [PATCH 13/79] Make appservice-discord support both SQLite and
 Postgres

People can toggle between them now. The playbook also defaults
to using SQLite if an external Postgres server is used.

Ideally, we'd be able to create databases/users in external Postgres
servers as well, but our initialization logic (and `docker run` command,
etc.) hardcode too many things right now.

Subject: [PATCH 15/79] Simplify password for additional Postgres databases

Using the result of `password_hash` works for creating them,
but authentication seems to be failing with some tools like pgloader.

It's possible that we're not escaping things properly somewhere.
Ideally, it'd be nice to solve that. But the easier (and still
relatively safe/good) solution is to just turn that password hash
into a UUID that's safe for passing around without worrying about
escaping.

Subject: [PATCH 23/79] Rename Postgres-related variables (`matrix*database_*`
 -> `matrix*postgres_*`)

`matrix_SERVICE_database_engine` remains as it is - the only one with a
`_database_` infix. Postgres-related ones move to `_postgres_`.

Subject: [PATCH 24/79] Make --tags=import-generic-sqlite-db commands not pass
 a sensitive connection string around

Instead of passing the connection string, we can now pass a name of a
variable, which contains a connection string.

Both are supported for having extra flexibility.

Subject: [PATCH 28/79] Rename `_database_hostname` to `_postgres_hostname`

Should have been done during 2a99e84b5bfd9f39, but I've missed it.

Because of this, 9bf8ce878e945 was also incomplete and would have caused
an error.

Subject: [PATCH 30/79] Remove some remaining `_database_password` usage in
 favor of `_postgres_pasword`

The only one that remains is `matrix_synapse_database_password`, but
that's something old and should be dealt with separately in the future
(unless it remains as it is).

Subject: [PATCH 32/79] Fix sqlite usage for mautrix-facebook/mautrix-telegram

Regression since 2d99ade72f and 9bf8ce878e94, respectively.

When SQLite is to be used, these bridges expect an `sqlite://`
connection string, and not a plain file name (path), like Appservice
Discord and mautrix-whatsapp do.

Subject: [PATCH 34/79] Rename `matrix_*_postgres_*` back to
 `matrix_*_database_*`

I was thinking that it makes sense to be more specific,
and using `_postgres_` also separated these variables
from the `_database_` variables that ended up in bridge configuration.

However, @jdreichmann makes a good point
(https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/740#discussion_r542281102)
that we don't need to be so specific and can allow for other engines (like MySQL) to use these variables.

-        To continue using SQLite, opt into it explicitly: add `matrix_appservice_discord_database_engine: sqlite` to your vars.yml file and re-run this same command.
-        Alternatively, to migrate your existing SQLite database to Postgres:
-        1. Stop all services (`ansible-playbook -i inventory/hosts setup.yml --tags=stop`)
-        2. Import the SQLite database into Postgres (`ansible-playbook -v -i inventory/hosts setup.yml --tags=import-generic-sqlite-db --extra-vars='sqlite_database_path={{ matrix_appservice_discord_sqlite_database_path_local }} postgres_connection_string_variable_name=matrix_appservice_discord_database_connString'`)
-        3. Re-run the playbook (`ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`)

Subject: [PATCH 56/79] Prepare matrix-registation for (SQLite + Postgres)
 support

Auto-migration and everything seems to work. It's just that
matrix-registration cannot load the Python modules required
for talking to a Postgres database.

Tracked here: https://github.com/ZerataX/matrix-registration/issues/44

Until this gets fixed, we'll continue default to 'sqlite'.

We were referencing them from `group_vars/matrix_servers` since
recently, but there were no such variables and they weren't being put to
use.

Subject: [PATCH 60/79] Fix Postgres database importing/upgrading conflicts

We were running into conflicts, because having initialized
the roles (users) and databases, trying to import leads to
errors (role XXX already exists, etc.).

We were previously ignoring the Synapse database (`homeserver`)
when upgrading/importing, because that one gets created by default
whenever the container starts.

For our additional databases, it's a similar situation now.
It's not created by default as soon as Postgres starts with an empty
database, but rather we create it as part of running the playbook.

So we either need to skip those role/database creation statements
while upgrading/importing, or to avoid creating the additional database
and rely on the import for that. I've gone for the former, because
it's already similar to what we were doing and it's simpler
(it lets `setup_postgres.yml` be the same in all scenarios).

Subject: [PATCH 62/79] Add support for executing additional DB migration
 statements

In cases where pgloader is not enough and we need to do some additional
migration work after it, we can now use
`additional_psql_statements_list` and
`additional_psql_statements_db_name`.

This is to be used when migrating `matrix-registration`'s data at the
very least.

Subject: [PATCH 63/79] Make matrix-registration use Postgres by default

Now that 0.7.2 is out, the Docker image supports Postgres
and we can do the (SQLite -> Postgres) migration.

I've also found out that we needed to fix up the `tokens.ex_date` column
data type a bit to prevent matrix-registration from raising exceptions
when comparing `datetime.now()` with `ex_date` coming from the database.

Example:

> File "/usr/local/lib/python3.8/site-packages/matrix_registration/tokens.py", line 58, in valid
> expired = self.ex_date < datetime.now()
> TypeError: can't compare offset-naive and offset-aware datetimes

Subject: [PATCH 69/79] Ensure mx-puppet-discord directories are created before

It's probably not necessary to keep it anymore, but since we still do,
at least we should take care to ensure it works.

-        matrix_mx_puppet_twitter_database_engine has been set to `postgres` (which is our new default now).
-        However, we've discovered an existing SQLite database in {{ matrix_mx_puppet_twitter_data_path }}/database.db.
-        It appears that you've been using this bridge with the SQLite engine until now.
-        To continue using SQLite, opt into it explicitly: add `matrix_mx_puppet_twitter_database_engine: sqlite` to your vars.yml file and re-run this same command.
-        Alternatively, to migrate your existing SQLite database to Postgres:
-        1. Stop all services (`ansible-playbook -i inventory/hosts setup.yml --tags=stop`)
-        2. Import the SQLite database into Postgres (`ansible-playbook -v -i inventory/hosts setup.yml --tags=import-generic-sqlite-db --extra-vars='sqlite_database_path={{ matrix_mx_puppet_twitter_data_path }}/database.db postgres_connection_string_variable_name=matrix_mx_puppet_twitter_database_connString'`)
-        3. Re-run the playbook (`ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`)
-    when: "matrix_mx_puppet_twitter_sqlite_database_path_local_stat_result.stat.exists"
