llvmPackages_{13,14,15,16,17,18,git}: commonify the default.nix by RossComputerGuy · Pull Request #325175 · NixOS/nixpkgs

RossComputerGuy · 2024-07-07T04:45:14Z

Description of changes

Drop all default.nix files for LLVM versions and simply the entrypoint to a common place. This will greatly reduce the amount of work to maintain LLVM and simply updating. Not bothering with LLVM 12 as it is a legacy version and it sits with the pre-monorepo setup which would increase complexity for this PR.

pkgs/development/compilers/llvm/default.nix

There are a couple of ways to implement this and I'm not deadset on anything specific, just adding suggestions.

Suggestion, untested! - feel free to ignore: condensed but possibly a bit opaque:

versions = { "13.0.1".officialRelease.sha256 = "06dv6h5dmvzdxbif2s8njki6h32796v368dyb5945x8gjj72xh7k"; "14.0.6".officialRelease.sha256 = "sha256-vffu4HilvYwtzwgq+NlS26m65DGbp6OSSne2aje1yJE="; "15.0.7".officialRelease.sha256 = "sha256-wjuZQyXQ/jsmvy6y1aksCcEDXGBjuhpgngF3XQJ/T4s="; "16.0.6".officialRelease.sha256 = "sha256-fspqSReX+VD+Nl/Cfq+tDcdPtnQPV1IRopNDfd5VtUs="; "17.0.6".officialRelease.sha256 = "sha256-8MEDLLhocshmxoEBRSKlJ/GzJ8nfuzQ8qn0X/vLA+ag="; "18.1.8".officialRelease.sha256 = "sha256-iiZKMRo/WxJaBXct9GdAcAT3cz9d9pnAcO1mmR6oPNE="; "19.0.0-git".gitRelease = { rev = "9b9405621bcc55b74d2177c960c21f62cc95e6fd"; rev-version = "19.0.0-unstable-2024-06-30"; sha256 = "sha256-Tlk+caav7e7H6bha8YQyOl+x2iNk9iH7xKpHQkWQyJ4="; }; } # ... llvmPackages = lib.mapAttrs' (version: args: mkPackage (args // { inherit version; })) versions

Another thought is to have a mechanism for overriding/extending it: take llvmVersions as a parameter defaulting to empty set. Then do versions // llvmVersions -- this would potentially allow users to override LLVM versions by putting llvmVersions = { ... } in their overlay. The issue I see with this is of keying the llvmPackage_{version} on the major version but having the attribute be a full version.

How would making the version list an attr set work with the officialRelease or gitRelease stuff?

That is already accounted for in my suggested code block, "13.0.1".officialRelease.sha256 expands to "13.0.1" = { officialRelease = { sha256 = ... }; } such that the only missing attribute is the version, which we reinject via mapAttrs' in mkPackage (args // { inherit version; } so that it reads officialRelease = { version = ..., sha256 = ...}. Then the last one is .gitRelease.

Ok, I made it work with an attr set.

If someone nixpkgs-review's this and there's a rebuild count of 0 before Ofborg gets to this, I'll merge this.

Weird CI error.

Couldn't rebase on GitHub website since I can't access one of my systems right now. Will fix up the commits as soon as I can, maybe this will fix the CI fail.

pkgs/top-level/aliases.nix

This was added to aliases to prevent packages in nixpkgs from using it. Dropping it from aliases would change that. Is it intended that llvmPackages_git be usable in nixpkgs going forward?

I don't really care if LLVM git is or isn't in alias. I just moved it so all versions past 12 are using the commonified default.nix. Probably isn't a bad idea either way so Ofborg tests for the weekly git updates.

This was in aliases.nix on purpose — if packages in Nixpkgs start relying on it, it blocks us from keeping it up to date, and the point of llvmPackages_git is to always be up to date. Could you please move it back?

(For the same reason, e.g. linuxPackages_latest is in aliases.nix on purpose, because when it wasn't it created tension between keeping it up to date and keeping dependent packages working.)

linuxPackages_latest is in aliases.nix on purpose

Where is linuxPackages_latest in aliases.nix? I don't see it in there.

Moved back into aliases.nix in #331880

Where is linuxPackages_latest in aliases.nix? I don't see it in there.

Sorry, I was mistaken about that. It's not in aliases.nix — it's been prevented from being used in Nixpkgs entirely through consistent review, and providing an alternative linuxHeaders package that doesn't promise to be "latest", even though in practice we update it as soon as we can.

RossComputerGuy · 2024-07-08T02:59:43Z

Huh, firefox.stdenv.cc.bintools is resulting in a different value that is causing a rebuild.

RossComputerGuy · 2024-07-08T03:31:34Z

It seems the recurse into attrs + call packages of the default.nix in mkPackage was causing issues.

Suggested change

&& !stdenv.targetPlatform.isAarch64

&& (lib.versionOlder darwin.apple_sdk.sdk.version "11.0")

&& lib.versionOlder stdenv.targetPlatform.darwinSdkVersion "11.0"

will align this with the changes in https://github.com/NixOS/nixpkgs/pull/324155/files

then, which ever change has to deal with the merge conflicts with the deleted files can just re-delete the files and everything should just work.

Sweet, I've made the change. Not gonna push until #324155 is merged.

Pull NixOS#320261 introduced the possibility to consistently override dependencies within an llvm package set. I think NixOS#325175 accidentally dropped this, so reinstate it. Signed-off-by: Peter Waller <[email protected]>
