Haskell GHC 8.10.7 & Stackage LTS 18.28

Summary

The GHC Haskell compiler will be updated from minor version 8.10.5 to 8.10.7, and Haskell packages will be updated to Stackage LTS 18.28 minor versions.

Current status

Targeted release: Fedora Linux 37
Last updated: 2022-08-04

devel thread
FESCo issue: #2844
Tracker bug: #2115399
Release notes tracker: #873

Detailed Description

For Fedora 37, the GHC Haskell compiler will be updated from version 8.10.5 to 8.10.7 release (rebasing from the ghc8.10 package). Along with this, Haskell packages in Stackage (the stable Haskell source package distribution) will be updated to the final LTS 18.28 minor release. Haskell packages not in Stackage will be updated to the latest appropriate version in the upstream Hackage package repository.

Feedback

Benefit to Fedora

Fedora users will have a newer more stable Haskell compiler, tools, and current Haskell packages from final Stackage LTS 18.

GHC 8.10.7 contains some important bug fixes (see the release notes linked in the Documentation section for more details).

Scope

Proposal owners:
- rebase ghc to 8.10.7
- update ghc-rpm-macros to the final version for F37
- update packages to latest Stackage LTS 18 versions using cabal-rpm
- build all the packages in a Koji sidetag repo in dependency order using fbrnch
- push the sidetag through Bodhi to Rawhide before the mass rebuild [done]

Other developers: no actions should be needed

Policies and guidelines: N/A (not needed for this Change)

Trademark approval: N/A (not needed for this Change)

Alignment with Objectives:

Upgrade/compatibility impact

There should not be any significant upgrade impact, except that ghc-8.10.7 conflicts with ghc8.10: users should remove ghc8.10 from their system before upgrading.

Users' Haskell projects will get built with ghc-8.10.7 when they next build: 8.10.7 should be quite compatible with 8.10.5.

How To Test

install ghc and cabal-install
install pandoc, ShellCheck, ghcid, git-annex, hadolint, stack, xmonad
install ghc-*-devel or ghc-*-prof or ghc-*-doc
cabal-rpm builddep <favouritepackage>; cabal install <favouritepackage>
test upgrades of F36 Haskell packages to F37

User Experience

Users will have the newer stable minor version of ghc and Haskell libraries and tools available to them. This makes it easier to build the recent versions of Haskell projects.

Dependencies

Contingency Plan

Contingency mechanism: (What to do? Who will do it?)
- Change owner can revert back to the versions in F36.
Contingency deadline: Beta Freeze

Contingency mechanism: (What to do? Who will do it?) N/A (not a System Wide Change)
