Problem

When a repository with feed "https://repos.fedorapeople.org/pulp/pulp/fixtures/rpm-with-modules/" is created, synced and published, the updateinfo.xml of the published repo contains an inconsistent number of modules.

Steps to reproduce :

Create and sync a repo pointing to the rpm-with-modules fixture.

pulp-admin rpm repo create --feed https://repos.fedorapeople.org/pulp/pulp/fixtures/rpm-with-modules/ --repo-id test-repo

pulp-admin rpm repo sync run --repo-id test-repo

After the repo is synced, get the number of module tags present in the repo

# note the repo id and the timestamp directory after that can change
zcat 8147252315a121c89a1be2058fe3367a52bf81dac61788e53358c271421cd9d6-updateinfo.xml.gz |grep "module" | wc -l
33 # current output of the number of modules in the update_info.xml

If the above repository is deleted, and then again the same steps are followed for a new repo, the total number of modules in the new repo are seen to be increased

pulp-admin rpm repo delete --repo-id test-repo
pulp-admin rpm repo create --feed https://repos.fedorapeople.org/pulp/pulp/fixtures/rpm-with-modules/ --repo-id test-repo-new

pulp-admin rpm repo sync run --repo-id test-repo-new

zcat ef13ff9115725082dd55fef6251880d28d66c1b0acf28abf89ba7fd2b1ade96f-updateinfo.xml.gz |grep module |wc -l
36 # current output of the number of modules in the update_info.xml

As seen the number of modules have increased for the same feed url with different repo names.

Also the update-info.xml of the published repo is different comparing with the actual update-info.xml of the fixtures repo.

Have attached the update-info.xml of both the syncs and the fixtures repo.
