Re: rolling back only a single package

[cdelia]

Hi again,

This is odd, it doesn't downgrade:

$/var/guix/profiles/per-user/catriel/current-guix-1-link/bin/guix package -i 
xmobar
The following package will be upgraded:
   xmobar       0.28 -> 0.28    
/gnu/store/b7kyq7a7p622gf1cwyf4l29hz8840rj2-xmobar-0.28

$guix package -l
...
Generation 31   dic 30 2018 20:57:55    (current)
 + xmobar       0.28    out     
/gnu/store/b7kyq7a7p622gf1cwyf4l29hz8840rj2-xmobar-0.28
 - xmobar       0.28    out     
/gnu/store/crhjq02nz07wrycvyxr21z00n0g7wxwa-xmobar-0.28

The commit hash it's fine:

$guix pull -l
Generation 1    nov 10 2018 18:52:17
  guix e8b9aaf
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: origin/master
    commit: e8b9aaf0b167812dee6be26772837ef2a271a843

$/var/guix/profiles/per-user/catriel/current-guix-1-link/bin/guix --version
guix (GNU Guix) e8b9aaf0b167812dee6be26772837ef2a271a843

Installing xmobar it even builds ghc 8.4.3 derivation, when in guix
generation 1 it was 8.0.2 at most.

$guix package -l | grep -e Generation -e ghc
Generation 21   nov 30 2018 16:09:52
 + ghc  8.0.2   out     /gnu/store/ljcgfckycml8a2vj47w6ywwn4vdw20zv-ghc-8.0.2

...
Generation 27   dic 08 2018 18:42:03
 + ghc  8.4.3   out     /gnu/store/564215v4ma3jqxai20hf1ymcrn60nm44-ghc-8.4.3
 + ghc-xmonad-contrib   0.14    out     
/gnu/store/ckklwgqi1hxgcrbpsd9myslwz5p2mgxw-ghc-xmonad-contrib-0.14
 - ghc-xmonad-contrib   0.13    out     
/gnu/store/fdkdysalmg8fb5jcyn0wz2jh4syaf6mv-ghc-xmonad-contrib-0.13
 - ghc  8.0.2   out     /gnu/store/ljcgfckycml8a2vj47w6ywwn4vdw20zv-ghc-8.0.2
Generation 28   dic 09 2018 21:44:29
...


If I do 

$/var/guix/profiles/per-user/catriel/current-guix-1-link/bin/guix edit xmobar

or

$/var/guix/profiles/per-user/catriel/current-guix-1-link/bin/guix edit ghc

I see the the currents versions (0.28 and 8.4.3) defined in the packages.


So I'm not shure what's goin on here.

I installed xmobar the 30 of november.

Generation 18   nov 30 2018 12:10:17
 + xmobar       0.26    out     
/gnu/store/d0xc7k7i73dqdzw1cjwg6cypmm3fp8d3-xmobar-0.26

By that time I had got generation 1 of guix:

$guix pull -l | head -n 2
Generation 1    nov 10 2018 18:52:17
Generation 2    nov 30 2018 21:21:28

this's weird.

I don't think I had corrupted my guix installation, never touched the
store and never did anything fancy...

maybe I'm reading something the wrong way?
