This implements the option for a gradual migration to stricter checks.
For now this is only done for the check against empty non-auto-called
callPackage arguments, but in the future this can be used to ensure all
new packages make use of `pkgs/by-name`.
This is implemented by adding a `--base <BASE_NIXPKGS>` flag, which then
compares the base nixpkgs against the main nixpkgs version, making sure
that there are no regressions.
The `--version` flag is removed. While it was implemented, it was never
used in CI, so this is fine.
This prepares the code base for the removal of the `--version` flag, to
be replaced with a flag that can specify a base version to compare the
main Nixpkgs against, in order to have gradual transitions to stricter
checks.
This refactoring does:
- Introduce the `version` module that can house the logic to increase
strictness, with a `version::Nixpkgs` struct that contains the
strictness conformity of a single Nixpkgs version
- Make the check return `version::Nixpkgs`
- Handle the behavior of the still-existing `--version` flag with `version::Nixpkgs`
- Introduce an intermediate `process` function to handle the top-level
logic, especially useful in the next commit
Convenience function to run another validation over a successful validation result.
This will be usable in more locations in future commits, making the code
nicer.
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
While using very old compilers is a fair usecase, it induces a maintenance churn as
we collect more and more LLVM versions for the LLVM maintainers.
Especially when we need to backport uniform changes to the whole tree,
furthermore, it consumes and waste CI resources.
- passing it as expression gives large error messages
which are not very readable
- this commits puts the file in nix-store
and patches the final program to have access to
the path to the file as env.
- We simply pass this file to nix-instantiate
We have several cross-compilation bugs that show up if
hostPlatform!=buildPlatform yet
hostPlatform.config==buildPlatform.config.
These bugs have appeared and disappeared as we've fiddled with the
definition of equality for platform objects. This commit adds a
clear-cut case where they are *not* equal and never will be, so we
can test it.
