mysql already has its socket path hardcoded to to
/run/mysqld/mysqld.sock.
There's not much value in making the pidDir configurable, which also
points to /run/mysqld by default.
We only seem to use `services.mysql.pidDir` in the wordpress startup
script, to wait for mysql to boot up, but we can also simply wait on the
(hardcoded) socket location too.
A much nicer way to accomplish that would be to properly describe a
dependency on mysqld.service. This however is not easily doable, due to
how the apache-httpd module was designed.
As we don't need to setup data directories from ExecStartPre= scripts
anymore, which required root, but use systemd.tmpfiles.rules instead,
everything can be run as just the mysql user.
define commands like "waiting for the mysql socket to appear" or "setup
initial databases" in a let expression, so the main control flow becomes
more readable.
We need to keep using `RuntimeDirectory=mysqld`, which translates to
`/run/mysqld`, as this is used for the location of the file socket, that
could differ with what is configured via `cfg.pidDir`.
This was a testing oversight that came from #61009 -- I forgot to test
the new traceFormat option with older server versions while I was
working on FDB 6.1.
Since trace_format is only available in 6.1+, emitting it
unconditionally caused older versions of the database fail to start,
reporting an error. We simply gate it behind a version check instead,
and assert the format is always XML on older versions. This avoids the
case where the user has an old version, changes traceFormat willingly,
and then is confused by why it didn't work.

Prevent it from getting copied to nix store as people might use it for
credentials, and make the tests cover it.
The default, which is /tmp, has a few issues associated with it:
One being that it makes it easy for users on the system to spoof a
PostgreSQL server if it's not running, causing applications to connect
to their provided sockets instead of just failing to connect.
Another one is that it makes sandboxing of PostgreSQL and other services
unnecessarily difficult. This is already the case if only PrivateTmp is
used in a systemd service, so in order for such a service to be able to
connect to PostgreSQL, a bind mount needs to be done from /tmp to some
other path, so the service can access it. This pretty much defeats the
whole purpose of PrivateTmp.
We regularily run into issues with this in the past already (one example
would be https://github.com/NixOS/nixpkgs/pull/24317) and with the new
systemd-confinement mode upcoming in
https://github.com/NixOS/nixpkgs/pull/57519, it makes it even more
tedious to sandbox services.
I've tested this change against all the postgresql NixOS VM tests and
they still succeed and I also grepped through the source tree to replace
other occasions where we might have /tmp hardcoded. Luckily there were
very few occasions.

The default galera_new_cluster script tries to set this environment
variable using systemctl set-environment which doesn't work if the
variable is not being used in the unit file ;)
Although the package itself builds fine, the module fails because it
tries to log into a non-existant file in `/var/log` which breaks the
service. Patching to default config to log to stdout by default fixes
the issue. Additionally this is the better solution as NixOS heavily
relies on systemd (and thus journald) for logging.
Also, the runtime relies on `/etc/localtime` to start, as it's not
required by the module system we set UTC as sensitive default when using
the module.
To ensure that the service's basic functionality is available, a simple
NixOS test has been added.
As cassandra start script hardcodes the location of logback
configuration to `CASSANDRA_CONF_DIR/logback.xml` there is no way to
pass an alternate file via `$JVM_OPTS` for example.
Also, without logback configuration DEBUG level is used which is not
necessary for standard usage.
With this commit a default logback configuration is set with log level
INFO.
