This Merge

This PR is the regular merge of the haskell-updates branch into staging. This time we are upgrading our default GHC version from the 9.8 to the 9.10 series and Stackage LTS from 23 to 24 to match.

This branch is being continually built and tested by hydra at https://hydra.nixos.org/jobset/nixpkgs/haskell-updates. You may be able to find an up-to-date Hydra build report at cdepillabout/nix-haskell-updates-status.

A Stackage/default compiler upgrade is a big job, so we hope for contributions from outside the core @NixOS/haskell team. Try checking for the state of your favorite packages on Hydra and attempt to fix regressions.

haskellPackages Workflow Summary

Our workflow is currently described in pkgs/development/haskell-modules/HACKING.md.

The short version is this:

  • We regularly update the Stackage and Hackage pins on haskell-updates (normally at the beginning of a merge window).
  • The community fixes builds of Haskell packages on that branch.
  • We aim at at least one merge of haskell-updates into staging every two weeks.
  • We only do the merge if the mergeable job is succeeding on hydra.
  • If a maintained package is still broken at the time of merge, we will only merge if the maintainer has been pinged 7 days in advance. (If you care about a Haskell package, become a maintainer!)

More information about Haskell packages in nixpkgs can be found in the nixpkgs manual.

This is the follow-up to #424162. Come to #haskell:nixos.org if you have any questions.

Test suite of say is broken because of haskell/text#648, we could apply the corresponding patch to the text 2.1.2 core library we ship with GHC 9.10.2, 9.12.1 and 9.12.2. Since text-2.1.3 has been released, we could also wait for 9.10.3 (rc1 is already out) and 9.12.3.

Alternatively, we would need to apply

to GHC's text (which effectively makes it 2.1.2, we could even bump the version number…).

Is it feasible to build and test that package with a downgraded Cabal as a workaround?

Is it feasible to build and test that package with a downgraded Cabal as a workaround?

Wouldn't it be enough to disable the tests for that package? Maybe even just that specific failing test, if possible. Seems to be a test-only problem according to that issue.

@roberth @wolfgangwalther, I think we have fix for that in Soostone/katip#159, I will coordinate hackage release with the fix. Hopefully, it's there soon.

I'm keeping an eye on nix-tree - right now it's broken because of data-clist which is broken because of the quickcheck change that you've noted before. I am a bit busy these days but hopefully I might be able to have a look at it over this weekend.
