LXC containers like those used by VPSAdminOS might want to install a bootloader
so passing `true` to `system.build.installBootLoader` without any priority specified,
causes a conflict for such systems with the recent `system.build` changes:

If the Nix daemon has never been enabled (nix.enable has always been
set to false), the gcroots directory won't exist. If the Nix daemon
is later enabled, the GC roots for booted-system and current-system
will be missing, and they might end up being garbage collected. Since
it's cheap to add GC roots even if the daemon will never be enabled,
let's just always add them so we're okay in the case where the daemon
is enabled later.
Replace sleep() calls where possible, using wait_for_* methods. This
should provide more robustness in cases where tests are running on a
congested system.
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.
`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.
Add a new type, inheriting 'types.str' but checking whether the value
doesn't contain any newline characters.
The motivation comes from a problem with the
'users.users.${u}.openssh.authorizedKeys' option.
It is easy to unintentionally insert a newline character at the end of a
string, or even in the middle, for example:
restricted_ssh_keys = command: keys:
let
prefix = ''
command="${command}",no-pty,no-agent-forwarding,no-port-forwarding,no-X11-forwarding
'';
in map (key: "${prefix} ${key}") keys;
The 'prefix' string ends with a newline, which ends up in the middle of
a key entry after a few manipulations.
This is problematic because the key file is built by concatenating all
the keys with 'concatStringsSep "\n"', with result in two entries for
the faulty key:
''
command="...",options...
MY_KEY
''
This is hard to debug and might be dangerous. This is now caught at
build time.
This commit introduces a new option
`services.nextcloud.nginx.recommendedHttpHeaders` that can be used to
optionally disable serving recommended HTTP Response Headers in nginx.
This is especially useful if some headers are already configured
elsewhere to be served in nginx and thus result in duplicate headers.
