Since https://github.com/NixOS/nixpkgs/pull/279892, there's a separate
check that makes sure all changed Nix files evaluate. To not trigger
that, we need to remove all invalid Nix expressions from the tests.
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.
Previously, not passing `--base` would enforce the most strict checks.
While there's currently no actual violation of these stricter checks,
this does not match the previous behavior.
This won't matter once CI passes `--base`, the code handling the
optionality can be removed then.
This makes it such that these two errors can both be thrown for a single
package:
- The attribute value not being a derivation
- The attribute not being a proper callPackage
The tests had to be adjusted to only throw the error they were testing
for
Allows detecting whether attributes are overridden in all-packages.nix.
In a future commit we'll use this to detect empty arguments being set in
all-packages.nix and complain about that.
- Better filesystem case-sensitivity heuristic
We shouldn't assume that Linux is always case-sensitive.
- Don't include case-sensitive filename in tree
Was used for tests, but this broke channel updates because there's a
check to make sure there's no case-sensitive files!
