I was sleepy and confused that "interpolated expression" was a new type of thing at first. This nudges the reader to understand that its just a regular expression, and these conditions are imposed by the interpolation operation.
Additionally this skipping of the building is reimplemented to be a bit
more robust and use the same idioms as the functionality for skipping
the tests. In particular, it will now work even if the source files
exist, so we can do this during development too.
I think the our `flake.nix` is currently too large and too scary looking.
I think this matters --- if Nix cannot dog-food itself in a way that is
elegant, why should other people have confidence that their own code can
be elegant and easy to maintain?
We could do this at many points in time, but I think around now, when we
are thinking about stabilizing parts of Flakes, is an especially good
time.
This is a first step to make the `flake.nix` smaller, and make
individual components responsible for their own packaging. I hope we can
do this many more follow-ups like it, until the top-level `flake.nix` is
very small and just coordinates between other things.
I think it is bad for these reasons when `tests/` contains a mix of
functional and integration tests
- Concepts is harder to understand, the documentation makes a good
unit vs functional vs integration distinction, but when the
integration tests are just two subdirs within `tests/` this is not
clear.
- Source filtering in the `flake.nix` is more complex. We need to
filter out some of the dirs from `tests/`, rather than simply pick
the dirs we want and take all of them. This is a good sign the
structure of what we are trying to do is not matching the structure
of the files.
With this change we have a clean:
```shell-session
$ git show 'HEAD:tests'
tree HEAD:tests
functional/
installer/
nixos/
```
A couple of tests require building some libraries that depend on Nix,
and assume it to be built locally.
Don't run these if we only want to run the install tests.
This prevents the CI from rebuilding several times Nix (like in
https://github.com/NixOS/nix/actions/runs/6404422275/job/17384964033#step:6:6412), thus removing a fair amount of build time.
the `term` output mode leaves inline HTML around verbatim, while `nroff`
mode (used for `man` pages) does not.
the correct solution would be to pre-render all output with a more
benign tool so we have less liabilities in our own code, but this has to
do for now.
This has been the behaviour before Nix 2.4. It was dropped in a rewrite
in 759947bf72, allowing the creation of
store paths that aren't considered valid by older Nix versions or other
Nix tooling.
Nix 2.4 didn't ship in NixOS until 22.05, and stdenv.mkDerivation in
nixpkgs drops leading periods since April 2022, so it's unlikely anyone
is relying on the current lax behaviour.
Closes#9091.

This was somewhat of a false alarm. The problem was not that the
protocol implementation actually failed to round trip, but that two of
the fields were ignored entirely --- not serialized and deserialized at
all.
For reference, those fields were added in
fa68eb367e.
