bug#28743: guix package dry-run upgrade incorrect behaviour with verbosity

[zimoun <zimon.toutoune@gmail.com>]

Hi,

This old bug [1] is about dry-run.  IIUC, it is not now fixed as shown
below.  However, there is another annoying thing about the option
’--verbosity’.

Let create a profile with a package without the grafts, then check the
update with dry-run, make the upgrade, check the dry-run upgrade again.
All seem fine, right?

However, let do the same thing with the option ’--verbosity=2’ (equal
deprecated ’--verbose’).

--8<---------------cut here---------------start------------->8---
$ rm -fr /tmp/foo*
$ guix package -i r-shiny -p /tmp/foo --no-grafts 2>/dev/null
$ guix package -p /tmp/foo --upgrade --dry-run --verbosity=2
The following package would be upgraded:
   r-shiny (dependencies or package changed)

$ guix package -p /tmp/foo --list-generations

$ guix package -p /tmp/foo --upgrade --verbosity=2
guix package: warning: nothing to do
--8<---------------cut here---------------end--------------->8---

Et voilà!  Still a bug.  Same with any other ’verbosity’ value.


All the best,
