Stack LTS 21.6 uses GHC 9.4.5, binaries for HLS are available via ghcup.
Changes required:
1. Fix warnings about type level `:` and `[]` used without backticks.
2. Fix warnings about deprecation of builtin `~` - replaced with `import
Data.Type.Equality ( type (~) )` in the Prelude
3. SemVer is no longer a monoid
4. `path-io` now contains the `AnyPath` instances we were defining
(thanks to Jan) so they can be removed.
5. Added `aeson-better-errors-0.9.1.1` as an extra-dep. The reason it is
not part of the resolver is only because it has a strict bound on base
which is not compatible with ghc 9.4.5. To work around this I've set:
```
allow-newer: true
allow-newer-deps:
- aeson-better-errors
```
which relaxed the upper constraint bounds for `aeson-better-errors`
only. When the base constraints have been updated we can remove this
workaround.
6. Use stack2cabal to generate the cabal.project file and to freeze
dependency versions.
https://www.stackage.org/lts-21.6/cabal.config now contains the
constraint `haskeline installed`, which means that the version of
haskeline that is globally installed with GHC 9.4.5 will be used, see:
* https://github.com/commercialhaskell/stackage/issues/7002
GHC 9.4.5 comes with haskeline 0.8.2 preinstalled but our configuration
contains the source-repository-package for haskeline 0.8.2.1 (required
because we're using a fork) so if you try to run` cabal build` you get a
conflict.
Constraints from cabal imports cannot yet be overridden so it's not
possible to get rid of this conflict using the import method. So we need
to use stack2cabal with an explicit freeze file instead.
7. Remove `runTempFilePure` as this is unused and depends on
`Polysemy.Fresh` in `polysemy-zoo` which is not available in the
resolver. It turns out that it's not possible to use the `Fresh` effect
in a pure context anyway, so it was not possible to use
`runTempFilePure` for its original purpose.
8. We now use https://github.com/benz0li/ghc-musl as the base container
for static linux builds, this means we don't need to maintain our own
Docker container for this purpose.
9. The PR for the nightly builds is ready
https://github.com/anoma/juvix-nightly-builds/pull/2, it should be
merged as soon as this PR is merged.
Thanks to @benz0li for maintaining https://github.com/benz0li/ghc-musl
and (along with @TravisCardwell) for help with building the static
binary.
* Closes https://github.com/anoma/juvix/issues/2166
This PR upgrades our Haskell configurations to compile with version
9.2.7. The checklist below can serve as a guide for similar future
updates:
- [x] Update Stack resolver in `stack.yaml`
- [x] Modify `tested-with` section in `package.yaml`
- [x] Build and push the new compiler docker image, see instructions
here
[docker/README.md](https://github.com/anoma/juvix/blob/main/docker/README.md):
`ghcr.io/paulcadman/ghc-alpine:9.2.7 container`.
- [x] Update Linux Github Action workflow in
`.github/workflows/linux-static-binary.yaml` and adjust
`docker/Dockerfile-ghc-alpine-9.2.7`
- [x] Revise GHC/Stack/Cabal versions in `.devcontainer/Dockerfile`
- [x] Refresh Cabal configuration in `cabal-project`
The binary inside the Juvix release archive is now named `juvix` so this
PR updates the script that unzips and adds the juvix binary to the
devcontainer PATH to expect this.
