Importing haskell packages from hackage doesn't apply metadata revisions

The hackage store of haskell packages allows maintainers to update package metadata directly on hackage without updating the associated archive of a package. For instance, the cabal file of the integer-logarithms package version 1.0.3 [0] has been updated since 1.0.3 was published, relaxing the constraints on some dependencies[1]. This means that, if I try to build the attached integer-logarithms.scm (created from guix import hackage integer-logarithms and modified to use ghc-8.8) I get the following error:

```

In ghc 8.8 the base version is 4.13, and the updated cabal file for integer-logarithms amends the constrants to allow that version.

The solution might be to use `cabal get` to download the archive instead of downloading the .tar.gz directly, or manually amending the cabal file after downloading.

I've run into the same problem, seems like fetching the revised cabal file would be the best bet. (In the meantime I've modified package definitions to make the metadata changes, but that is manual and certainly should be automated by import.)

Actually, this does exist in the Haskell build system in Guix, but seems to be undocumented and not used by the importer. You can add the following to the arguments (in the bootstrap package in this case) to use a metadata revision:

#:cabal-revision ("2" "0a6j3313vz7n7dn8abddyib4jggblaq89f87ib4imdwjxjajbm33")

The hash is from running guix hash file (where file = 2.cabal in this case, downloaded from Hackage). This should be part of the importer, to specify a revision or by default grab the latest, I would say.

(and I'm guessing you know this is packaged in guix as integer-logarithms, without the "ghc-" prefix for some reason; not the only package like that I've noticed)

Ah yes, good catch! I agree that the fix should be to amend the importer, such that it finds out about these revisions and automatically uses the latest one.

Actually, upon closer inspection, that's exactly what it does! Instead of actually using the importer in my original example (as I claimed), I had actually just modified the code from gnu/packages/haskell-xyz.scm. Doing a fresh import correctly picks up that there is a new revision of the cabal file and produces the right derivation. I'll close this issue.

Yes, I noticed that later too on some packages I'm working on. Glad you got it sorted out.

Still should be documented somewhere, I guess under the build systems.
