How to repoquery without false-evaluated conditional requires?

[Miro Hrončok]

Hello.

I need to repoquery rawhide and rawhide-source for dependency on python3-toml.

Unfortunately, due to pyproject-rpm-macros, 413 packages BuildRequire:

(python3dist(toml) if python3-devel < 3.11)

I am not interested in this dependency because python3-devel on rawhide is 3.11+.

When I run a naïve repoquery on my Fedora 35 machine (with python3-devel 3.10), 
like this:

$ repoquery --repo=rawhide{,-source} --whatrequires python3-toml

I get all the 413 packages in the results. I kinda expected that.

I've tried:

$ repoquery --installroot ~/tmp/non-existent ... --whatrequires python3-toml

No dice, returns the same list as the first repoquery.

Then I've tried to podman into a rawhide container and run a repoquery there. 
When I have no pytohn3-devel installed or when I have python3-devel 3.11+ 
installed in the container, I still get all the packages that BR 
(python3dist(toml) if python3-devel < 3.11) only.

How do I filter them out?

I came up with this monstrosity:

for pkg in $(repoquery --repo=rawhide{,-source} --whatrequires python3-toml)
   do repoquery -q --repo=rawhide{,-source} --requires $pkg | \
      grep -Fv '(python3dist(toml) if python3-devel < 3.11)' | \
      grep -Eq '\btoml\b' && echo $pkg
done | tee toml-requires

But it is very slow and might contain false finds.

Do you know a better trick?

I feel repoquery should respect --installroot. It needs to take @system
repository (i.e. installad packages) from somewhere. --instalroot is that
place. If DNF does not do that, I recommend filing a bug.
