2023-11-24lib.systems.elaborate: fix passing `rust`Alyssa Ross1-92/+92
Usually, attributes passed explicitly to elaborate take precedence over the elaborated ones, but since we also elaborate the nested "rust" attrset, we need to push that one level down, so the rest of "rust" is still filled in if you just pass { rust = { config = ... } }. I've had to drop the assertion that checked that at most one of "rust" and "rustc" was part of the un-elaborated system, because doing this broke passing an elaborated system in, which should be idempotent. For the same reason, I've also had to make it possible for rust.rustcTargetSpec to be passed in. Otherwise, on the second call, since platform was filled in by the first, the custom target file would be constructed. The only other way to avoid this would be to compare the platform attrs to all built in Rust targets to check it wasn't one of those, and that isn't feasible. Fixes: e3e57b8f1885 ("lib.systems: elaborate Rust metadata") (cherry picked from commit 886c89287f6a35adb6eb9230a3a0cccf682d0f88)

2023-11-18lib.tests: build nix without flaky aws-sdk-cppAdam Joseph3-5/+26
The aws-sdk-cpp tests are flaky. Since pull requests to staging cause nix to be rebuilt, this means that staging PRs end up getting false CI failures due to whatever is flaky in the AWS SDK tests. Since none of our CI needs to (or should be able to) contact AWS S3, let's just omit it all. Bonus: the tests build way faster.

2023-11-15lib.fileset.fileFilter: Restrict second argument to pathsSilvan Mosberger4-31/+52
While this change is backwards-incompatible, I think it's okay because: - The `fileFilter` function is not yet in a stable NixOS release, it was only merged about [a month ago](https://github.com/NixOS/nixpkgs/pull/257356). - All public uses of the function on GitHub only pass a path - Any `fileFilter pred fileset` can also be expressed as `intersection fileset (fileFilter pred path)` without loss of functionality. - This is furthermore pointed out in the new error message when a file set is passed

2023-11-09lib: add asserts.assertEachOneOfProfpatsch1-0/+29
Along the lines of `assertOneOf`, but expects a list of values to be compared. This gives a good error message and is useful for lists of values, like `supportedGhcVersions` in the arguments of `haskell-language-server`.
2023-11-09lib.systems: elaborate Rust metadataAlyssa Ross1-2/+98
We need this stuff to be available in lib so make-derivation.nix can access it to construct the Meson cross file. This has a couple of other advantages: - It makes Rust less special. Now figuring out what Rust calls a platform is the same as figuring out what Linux or QEMU call it. - We can unify the schema used to define Rust targets, and the schema used to access those values later. Just like you can set "config" or "system" in a platform definition, and then access those same keys on the elaborated platform, you can now set "rustcTarget" in your crossSystem, and then access "stdenv.hostPlatform.rustcTarget" in your code. "rustcTarget", "rustcTargetSpec", "cargoShortTarget", and "cargoEnvVarTarget" have the "rustc" and "cargo" prefixes because these are not exposed to code by the compiler, and are not standardized. The arch/os/etc. variables are all named to match the forms in the Rust target spec JSON. The new rust.target-family only takes a list, since we don't need to worry about backwards compatibility when that name is used. The old APIs are all still functional with no warning for now, so that it's possible for external code to use a single API on both 23.05 and 23.11. We can introduce the warnings once 23.05 is EOL, and make them hard errors when 23.11 is EOL.

2023-11-08lib.fileset: Make error messages more uniformSilvan Mosberger3-45/+47
Just minor changes like: - Always using "X is a Y, but it should be Z" - "X is a path that does not exist" rather than "X does not exist" - Always using multi-line strings for errors - Always quoting string-like values and not quoting path-like values - But do quote filesystem roots. Even though they're paths, they might be very small, good to have quotes to know the start/end - Capitalise the first word - Distinguish root vs filesystem root more
