Subject: bug#53162: ’guix shell ghc@8.4’ downloads ghc@8.10

Message-ID: <87zgo3woqs.fsf@gmail.com> (raw)
Hi,
Using 3dcc74d, I get an unexpected behaviour. First, all expected:
--8<---------------cut here---------------start------------->8---
$ guix build ghc@8.10 -n
122,4 MB would be downloaded:
/gnu/store/p8rk5cp1p4b2zky4zj1shfqb11qb5nmk-ghc-8.10.7-doc
/gnu/store/i92h6i23rnvrvn7xva6w9x7gjkljmfws-ghc-8.10.7
$ guix build ghc@8.4 -n
/gnu/store/5gp4k7ly1smhkx95rhq21nvxmyg687bv-ghc-8.4.4-doc
/gnu/store/wxfr2naibx3qpy4w243a7ga98mchf6g3-ghc-8.4.4
--8<---------------cut here---------------end--------------->8---
I have ghc@8.4 in my local store, but not ghc@8.10. In addition, no
path between ghc@8.4 and ghc@8.10,
--8<---------------cut here---------------start------------->8---
$ guix graph --path ghc@8.4 ghc@8.10
guix graph: error: no path from 'ghc@8.4.4' to 'ghc@8.10.7'
--8<---------------cut here---------------end--------------->8---
Even, ghc@8.4 is used in the bootstrap chain of ghc@8.10,
--8<---------------cut here---------------start------------->8---
$ guix graph --path ghc@8.10 ghc@8.4
ghc@8.10.7
ghc@8.8.4
ghc@8.6.5
ghc@8.4.4
--8<---------------cut here---------------end--------------->8---
However, tandam!
--8<---------------cut here---------------start------------->8---
$ guix shell -C ghc@8.4
The following derivation will be built:
/gnu/store/rx0spryh76az0ll6ddy7f7hy8ykhglnh-profile.drv
117,7 MB will be downloaded
ghc-8.10.7 112.3MiB 3.3MiB/s 00:01 [ ] 1.9% C-c C-c
--8<---------------cut here---------------end--------------->8---
From the profile.drv, the culprit is identified:
/gnu/store/…-ghc-package-cache.drv,
--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---
From my perspective, it is a bug from (guix profiles)
’ghc-package-cache-file’ which always includes ’ghc’, currently pointing
to ghc@8.10.
--8<---------------cut here---------------start------------->8---
(define ghc ;lazy reference
(module-ref (resolve-interface '(gnu packages haskell)) 'ghc))
--8<---------------cut here---------------end--------------->8---
Well, the fix is not jumping to my eyes. If someone has an idea to
conditionally remove this reference to ’ghc’?
Cheers,
simon
