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.
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 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
- 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
Currently the tool prints problems right as it is checking the code
without an intermediate error representation. However for various reasons
it would be beneficial to have an intermediate error type:
- It makes the code cleaner, having all errors in one place
- It allows printing the error in different ways, e.g. for a future
--json mode
This commit prepares for an incremental refactoring for an intermediate
error/problem representation. Most notable is that we want to be able to collect
multiple errors/problems and not just exit on the first one.
We introduce the type alias CheckResult and CheckError (later renamed to
NixpkgsProblem), where CheckError allows collecting multiple
CheckErrors using the utility function flatten_check_results (later
renamed to check_result::sequence)
The write_check_result function is only temporarily introduced to help
refactoring, it's removed again in later commits.
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.
