haskellPackages: update stackage and hackage

[ncfavier]

This Merge

This PR is the regular merge of the haskell-updates branch into master.

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.

We roughly aim to merge these haskell-updates PRs at least once every two weeks. See the @NixOS/haskell team calendar for who is currently in charge of this branch.

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 master 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 #296524. Come to #haskell:nixos.org if you have any questions.

Let me delay these builds for a couple days, until PR #298548 gets merged (hopefully, in a day or two).

Currently only two relevant appearing build errors on the branch:

• [📱❌] [🐧❌] carp @jluttine
• [📱❌] [🐧❌] haskellPackages.eventlog2html @maralorn

I’ll look into the eventlog thing, not immediately sure what to do about carp.

We also have an eval error on darwin:

in job ‘haskell.compiler.ghc963Binary.x86_64-darwin’:
error: Failed to evaluate ghc-binary-9.6.3: «broken»: is marked as broken

What’s going on there?

I’ll look into the eventlog thing, not immediately sure what to do about carp.

Carp repo seems pretty inactive. I asked if it's still maintained at all: carp-lang/Carp#1462

[maralorn]

@jluttine So, would it be okay for you if we marked Carp broken for the time being?
