Packages with GHC 9.2 language extensions rejected

[georgefst]

I can't upload a package to Hackage that uses recent extensions:

cabal upload --publish /home/gthomas/code/lifx-lan/dist-newstyle/sdist/lifx-lan-0.7.tar.gz
Uploading
/home/gthomas/code/lifx-lan/dist-newstyle/sdist/lifx-lan-0.7.tar.gz...

Error: Invalid package

Unknown extensions: NoFieldSelectors, OverloadedRecordDot

Possibly related to #1016?

Not related to #1016. hackage-server can be built against Cabal-3.6 with old GHCs as well. The upgrades are better done separately. (GHC is somewhat straight-forward, upgrading used Cabal is often more complicated).

[andreasabel]

A first stab is at

• GHC 9.0 and Cabal 3.4 (fix #1016) #1031. This would at least allow GHC 9.0 language extensions.

[andreasabel]

OP may be fixed by:

• Minimal migration to Cabal-3.6.3.0 #1038

[georgefst]

I am still getting the same error. Is that just because the fix hasn't yet been deployed?

[gbaz]

Yes, we're planning a redeploy tomorrow, tentatively.

[georgefst]

Awesome! I managed to upload the package.

Although building fails because the server appears to be running GHC 8.10.7. Does that mean #1040 wasn't deployed simultaneously?

[georgefst]

Does that mean #1040 wasn't deployed simultaneously?

Ah, just noticed #1040 is an issue, not a PR. Was that closed erroneously?

[gbaz]

No -- that is about being able to build hackage server itself with ghc 9.2. Moving the hackage-builder to build haddocks using another version of ghc is something else entirely.
