libsoup_2_4: Rename from libsoup

[jtojnar]

The 2.4 ABI branch has not been supported by upstream for a while now but people still keep accidentally adding it to new packages.

See #360897

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• 25.05 Release Notes (or backporting 24.11 and 25.05 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking
  • (Module updates) Added a release notes entry if the change is significant
  • (Module addition) Added a release notes entry if adding a new NixOS module
• Fits CONTRIBUTING.md.

Not much we can do about that if we do not want to break eval without aliases. Well, we could place the alias to all-packages.nix instead, modify cabal2nix to use the new name, and then move it to aliases.nix but that sounds like to much bother.

[maralorn]

Well, we have to do something about it. I see two options: Either add overrides for these packages in configuration-nix.nix or in cabal2nix. I assume @sternenseemann has an opinion on what’s right here.

I mean in theory we don’t even know if the Haskell packages build with the newer libsoup.

[jtojnar]

It is not a new version, only the attribute name changed.

[sternenseemann]

We should probably do the same as we did with the attribute name rename of webkitgtk:

• Change cabal2nix to emit versioned attributes where the ABI version is statically known, but otherwise emit a dependency on a generic libsoup attribute (may it exist in nixpkgs or not). C.f. Name: use explicit ABI version of webkitgtk cabal2nix#629.
• In the cases where no versioned attribute was generated, manually add overrides to configuration-common.nix: pkg = super.pkg.override { libsoup = pkgs.…; }. (I think with webkitgtk we didn't need to do this because all relevant packages use pkg-config which has the ABI version in the pc module name.)

[jtojnar]

Opened NixOS/cabal2nix#635

Edit: Rebased and added lib.warnOnInstantiate to the alias.

[sternenseemann]

I've added the cabal2nix-unstable update to 2476dd6, so hackage-packages.nix should be reproducible using the generation script again.

The libsoup -> libsoup_2_4 rename breaks the updateScript which then breaks the updateScript fetcher for the nixpkgs-update bot.

Can we remove the updateScript from libsoup_2_4?
