Add test coverage for the enableConfiguredRecompile option, checking
that we can compile and exec a new xmonad from a user's local config, as
well as restart the originally configured xmonad.
As I needed a reliable way to wait for recompilation to finish before
proceeding with subsequent test steps, I adjusted the startup behavior
to write a file ("oldXMonad" or "newXMonad") to /etc upon startup, and
replaced some "sleep" calls with "wait_for_file".
Update the example config to show a working example for xmonad 0.17.0, which
added an argument to the `launch` function and adjusted the location of the
recompiled binary.
Since release 1.18.4, the ModemManager daemon no longer automatically
performs the FCC unlock procedure by default. The user must, under their
own responsibility, enable the automatic FCC unlock as shipped by
ModemManager.
`assert` has the annoying property that it dumps a lot of code at the
user without the built in capability to display a nicer message. We have
worked around this using `assertMsg` which would *additionally* display
a nice message. We can do even better: By using `throw` we can make
evaluation fail before assert draws its conclusions and prevent it from
displaying the code making up the assert condition, so we get the nicer
message of `throw` and the syntactical convenience of `assert`.
Before:
nix-repl> python.override { reproducibleBuild = true; stripBytecode = false; }
trace: Deterministic builds require stripping bytecode.
error: assertion (((lib).assertMsg (reproducibleBuild -> stripBytecode)) "Deterministic builds require stripping bytecode.") failed at /home/lukas/src/nix/nixpkgs/pkgs/development/interpreters/python/cpython/2.7/default.nix:45:1
After:
nix-repl> python.override { reproducibleBuild = true; stripBytecode = false; }
error: Deterministic builds require stripping bytecode.
The `extraConfig` parameter only handles text - it doesn't support
arbitrary secrets and, with the way it's processed in the setup
script, it's very easy to accidentally unescape the echoed string and
run shell commands / feed garbage to bash.
To fix this, implement a new option, `config`, which instead takes a
typed attribute set, generates the `.env` file in nix and does
arbitrary secret replacement. This option is then used to provide the
configuration for all other options which change the `.env` file.
When upgrading bookstack, if something in the cache conflicts with the
new installation, the artisan commands might fail. To solve this, make
the cache lifetime bound to the setup service. This also removes the
`cacheDir` option, since the path is now handled automatically by
systemd.
