Since https://github.com/NixOS/nixpkgs/pull/281374, the
nixpkgs-check-by-name tooling is pinned to a specific /nix/store path to
avoid having to evaluate Nixpkgs in CI.
The same path is used for local runs, but that doesn't actually work
when you're trying to run it on a platform different from CI.
This commit makes it work by being clearer about platforms and making
local runs check out the correct Nixpkgs to evaluate the tool from.
Before this, the tool for CI would update when nixos-unstable updated,
which is kind of terrible because you don't know when it happens, and it
might break master.
In fact, the tooling _right now_ has a serious bug and shouldn't be used!
This PR addresses this by _pinning_ the tooling in Nixpkgs itself.
Updating the tooling now requires two PRs:
- The first PR to update the tooling source
- (wait for Hydra to build and publish it in nixos-unstable)
- The second PR to update the pinned tooling
In turn you know exactly when the changes are going to take effect.
This change however has additional benefits:
- It makes CI more reproducible, because it doesn't depend on the state
of nixos-unstable anymore
- Updates to the tooling can be tested with the workflow itself,
because PRs that update the pinned tool will be tested on the updated
version
- CI gets a sizable speed boost, because there's no need to download and
evaluate a channel anymore
- It makes it more realistic to move the source of the tool into a
separate repository
- It removes the brittle branch-specific logic that was previously
needed to ensure that release branches use their own version of the
tooling.
nix-build failed because the tests assume to run in a CWD equal to the
project root, which is not the case in the derivation build.
This commit fixes it by not using hacky `..` references to paths,
and instead uses NIX_PATH for all implicit Nix testing path
dependencies.
Also the root of the `lib` path gets passed in from the `default.nix`
file, so all the relative path handling is done by Nix during evaluation
already, and in the Nix store when possible.

- Rename AttributeRatchet to ToNixpkgsProblem
- Make the compare trait method into a RatchetState method

All other functions are in the form of `*{c,C}heckpointBuild*`, so we
deprecate the `mkCheckpointedBuild` function in favor of `mkCheckpointBuild`.
Also address some inconsistencies in the docs: some `buildOutput` should
actually be `incrementalBuildArtifacts`.
This makes the attribute ratchet check logic more re-usable, which will
be used in a future commit.
It also renames the ratchet states to something more intuitive
This commit adds a test for the newly added support for
__structuredAttrs in autoPatchelf(hook). It copied a reasonably
small-closure binary derivation that makes use of autoPatchelf, stripped
it down for the purpose of the test, and check that autoPatchelf
correctly set the interpreter and runpath whether __structuredAttrs is
set to true or not.
Due to the check soon depending on the base branch (see `--base`),
the CI check can't reasonably share all code with a local check.
We can still make a script to run it locally, just not sharing all code.
