Description

To reproduce:

  • Pulp 3: sync/publish/distribute RHEL8 Appstream (which has a group "conflicts-appstream" which has an empty packagelist)

Pulp 3 uses libcomps to generate a comps.xml file and it doesn't generate empty XML elements.
Pulp 2 expects packagelist to be always present, even if empty.
It also seems to be a mandatory however it is according to the unofficial spec.

Revision 84e42021 | View on GitHub

Configure createrepo_c to always generate packagelist element within a package group.

Pulp 2 relies on the packagelist element being present, even if it's empty. It also seems to be a mandatory element according to this unofficial spec https://pagure.io/rpm-metadata/blob/master/f/fedora/comps-schema/comps.dtd#_6

Before this fix, the packagelist element would only be generated if there is at least one package in a group.
