ghc 8.10.3

[carlocab]

Created with brew bump-formula-pr.

resource blocks may require updates.

[carlocab]

Rebased against master to incorporate fix for allureofthestars (#67259).

[fishtreesugar]

Adga build failed because the bound of transformers is too tight, and fixed in upstream

[carlocab]

Thanks. Would you know if any of the other builds are failing because of version specifications that are unnecessarily strict?

[fishtreesugar]

Thanks. Would you know if any of the other builds are failing because of version specifications that are unnecessarily strict?

I roughly browse the error messages, it seems that is the only one error cause by too strict version bound.

cabal: Invalid package ID: .

elm failed with weird error message, I guess it causes by cabal-install. I will investigate it later.

[fishtreesugar]

@carlocab carlocab I patched the elm formula #67404, you can give it a try.

11.0:

brew linkage --test allureofthestars
brew install --build-from-source elm
brew install --build-from-source jupyterlab
brew fetch --retry youtube-dlc
brew install --verbose --build-bottle git-annex
brew install --verbose --build-bottle hledger

10.15:

brew linkage --test allureofthestars
brew install --build-from-source bond
brew install --build-from-source elm
brew fetch --retry youtube-dlc

10.14:

brew linkage --test allureofthestars

brew install --build-from-source elm
brew fetch --retry youtube-dlc

git-annex and hledger still failed with:

can't load framework: Cocoa (not found)

Because they are using wrong ghc version: git-annex build dependency still require ghc@8.6 and hledger use stack with lts-16.25 snapshot which ghc version is 8.8.4

[carlocab]

Good catch. I should've checked that. What is the correct resolver to use for hledger so that it uses ghc 8.10.3?

Stack doesn't support ghc 8.10.3, currently commercialhaskell/stack#5463.

[carlocab]

That's annoying. I suppose it doesn't help to let stack just vendor its own ghc for the build? I suspect that that runs into similar Big Sur incompatibility issues. Not to mention that Homebrew stack is outdated.

[fishtreesugar]

Yes, what we can do is waiting for a new stackage snapshot with ghc 8.10.3 support :(

[carlocab]

How difficult would it be to switch hledger to a vanilla cabal v2-install?

Tagging @simonmichael, who might have ideas on how to get hledger to build with ghc 8.10.3.

[simonmichael]

@carlcab thanks for working on this. I can switch hledger back to cabal but I would prefer not to; I switched to stack to fix CI failures with cabal.

Once ghc-8.10.3 is available in homebrew, I can make the hledger formula use it, without waiting for a new stackage snapshot. But is there a chicken and egg problem here ? ghc can't be updated unless hledger builds, and it's not easy to temporarily disable the hledger formula ? I'll go ahead and make this update so that possibly both can be merged at the same time.

[carlocab]

Yes, please open a PR to fix hledger for ghc 8.10.3. That will make it easy for me to add your commit fixing hledger to this one.

[simonmichael]

44c7fdd5 pushed [to #66599], it might work when combined with this PR.

[simonmichael]

@carlocab please try 5d7c609418, which uses the old cabal build method.

[carlocab]

The old cabal build method has been disabled, so you can no longer use it, unfortunately.

[simonmichael]

Oh dear. Meaning, I should use cabal v2-install like in git-annex.rb ? I assumed brew's cabal-install (3.2) is new enough so that "install" is equivalent to "v2-install", but perhaps there's more to it and testing would take a while. I'll pursue this when I can. Is hledger is the only blocker here ? If there's a way to disable it temporarily without actually removing hledger.rb, I'd be fine with that.

[carlocab]

Yes.

there's more to it

There is, but not much more. The issue is that the old hledger formula used a special method called install_cabal_package, which no longer exists. You may wish to look at agda to see how I tried to get around it. (I may have done it wrong, tbh; I don't really know how to use cabal. However, it works.)

[carlocab]

Ok, dropped hledger from this PR.

With any luck, the only CI error from the next run should be just hledger on Big Sur (and possibly a whole lot of failures on the ARM runner if that's active now).

If this is the case then I intend to merge this PR as is, since hledger doesn't have any Big Sur bottles anyway. #65000 (Someone please warn me if that's a mistake.)

[fxcoudert]

Sorry, I've killed CI because we couldn't have used to bottles on Big Sur anyway, due to #67713

You'll need to rebase on top of master and push to start it again

[carlocab]

Yes, I was expecting that. I actually wanted to ping you here to check, but I figured you were busy fighting fires elsewhere and it could wait. Rebasing against master.

The kids, mostly 😸

@carlocab has triggered a merge.

[carlocab]

@fishtreesugar looks like haskell-stack now supports ghc 8.10.3: commercialhaskell/stackage-content@812b7e6

[fishtreesugar]

@carlocab Still not show on https://www.stackage.org

[carlocab]

That's annoying. I wonder if this setting help: https://docs.haskellstack.org/en/stable/yaml_configuration/#allow-newer

[fishtreesugar]

If it failed at compiler version checking, try below config may help.

system-ghc: true
resolver: nightly-2020-12-14
compiler: ghc-8.10.3
compiler-check: newer-minor

[simonmichael]

Right, there isn't a new stackage snapshot tested with GHC 8.10.3 yet, but stack now has the ability to build with GHC 8.10.3 at least. Let's see if efb0f42 at #66599 succeeds.
