Also make the attribute name to match the domain name.
This is more in line with the home-assistant custom component ecosystem
and allows additional validation between the derivation and the manifest.
Also, at a later time, this will enable us to check for domain conflicts
at eval time.
Closes#216989
First of all, a bit of context: in PostgreSQL, newly created users don't
have the CREATE privilege on the public schema of a database even with
`ALL PRIVILEGES` granted via `ensurePermissions` which is how most of
the DB users are currently set up "declaratively"[1]. This means e.g. a
freshly deployed Nextcloud service will break early because Nextcloud
itself cannot CREATE any tables in the public schema anymore.
The other issue here is that `ensurePermissions` is a mere hack. It's
effectively a mixture of SQL code (e.g. `DATABASE foo` is relying on how
a value is substituted in a query. You'd have to parse a subset of SQL
to actually know which object are permissions granted to for a user).
After analyzing the existing modules I realized that in every case with
a single exception[2] the UNIX system user is equal to the db user is
equal to the db name and I don't see a compelling reason why people
would change that in 99% of the cases. In fact, some modules would even
break if you'd change that because the declarations of the system user &
the db user are mixed up[3].
So I decided to go with something new which restricts the ways to use
`ensure*` options rather than expanding those[4]. Effectively this means
that
* The DB user _must_ be equal to the DB name.
* Permissions are granted via `ensureDBOwnerhip` for an attribute-set in
`ensureUsers`. That way, the user is actually the owner and can
perform `CREATE`.
* For such a postgres user, a database must be declared in
`ensureDatabases`.
For anything else, a custom state management should be implemented. This
can either be `initialScript`, doing it manual, outside of the module or
by implementing proper state management for postgresql[5], but the
current state of `ensure*` isn't even declarative, but a convergent tool
which is what Nix actually claims to _not_ do.
Regarding existing setups: there are effectively two options:
* Leave everything as-is (assuming that system user == db user == db
name): then the DB user will automatically become the DB owner and
everything else stays the same.
* Drop the `createDatabase = true;` declarations: nothing will change
because a removal of `ensure*` statements is ignored, so it doesn't
matter at all whether this option is kept after the first deploy (and
later on you'd usually restore from backups anyways).
The DB user isn't the owner of the DB then, but for an existing setup
this is irrelevant because CREATE on the public schema isn't revoked
from existing users (only not granted for new users).
[1] not really declarative though because removals of these statements
are simply ignored for instance: https://github.com/NixOS/nixpkgs/issues/206467
[2] `services.invidious`: I removed the `ensure*` part temporarily
because it IMHO falls into the category "manage the state on your
own" (see the commit message). See also
https://github.com/NixOS/nixpkgs/pull/265857
[3] e.g. roundcube had `"DATABASE ${cfg.database.username}" = "ALL PRIVILEGES";`
[4] As opposed to other changes that are considered a potential fix, but
also add more things like collation for DBs or passwords that are
_never_ touched again when changing those.
[5] As suggested in e.g. https://github.com/NixOS/nixpkgs/issues/206467
Prepare the tests for a change in dependency handling, by not relying on
bespoke files dropped into the package output.
Instead we now check the journal log for whether a configured component
was setup, once for the initial specialisation another time for the one
introducing esphome configuration.
Also improve abstractions for getting journal data relative to a cursor
and generally make a few things more concise.
Wait until home-assistant is fully reloaded or restarted to spot
possible errors during startup.
Swap out bluetooth_tracker for esphome, since the bluetooth tracker
causes errors, when it does not find a bluetooth device.
Drop mosquitto from the environment. It wasn't used since the 2022.3.0
release when MQTT stopped being configurable from the YAML config.
With multiple specialization changes this isn't very helpful anymore,
but no biggie since we check the log for errors anyway and the log is
not too verbose anyway.
There are now multiple combinations of how one can pass either
extraPackages or extraComponents. We now test those passed directly to
the package via an override, and those passed indirectly via the module,
that ultimately results in a second override to the package.
mosquitto needs a lot of attention concerning its config because it doesn't
parse it very well, often ignoring trailing parts of lines, duplicated config
keys, or just looking back way further in the file to associated config keys
with previously defined items than might be expected.
this replaces the mosquitto module completely. we now have a hierarchical config
that flattens out to the mosquitto format (hopefully) without introducing spooky
action at a distance.
The modules overrides extraComponents which leads to a costly rebuild of
the home-assistant package with all tests. Make it less costly by not
running the tests, as does the default for the package option. The
package's tests are already run by ofborg on every pull request as well
as by Hydra when building home-assistant.
Configures the emulated_hue component and expects CAP_NET_BIND_SERVICE
to be passed in order to be able to bind to 80/tcp.
Also print the systemd security analysis, so we can spot changes more
quickly.
We are running over 6000 tests by now and they take around 5 minutes
on faster machines and tests alot of components that endusers will not
actually be using. It is sufficient if we run them on package upgrades
and in the passthrough test.
