Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
Every time a repository sync is executed, pulp is downloading all the metadata files from the upstream repository. This generates big downloads, depending on the size of the repo, and a lot of time is wasted processing the same repodata again.
Version-Release number of selected component (if applicable):
satellite-6.10.1-2.el7sat.noarch
How reproducible:
Always
Steps to Reproduce:
1. Enable any repository (used Red Hat Enterprise Linux 8 for x86_64 - BaseOS RPMs 8 in my reproducer)
2. Sync it once
3. Sync it again. Check the details of the task from the second sync. Note the step "Downloading Metadata Files"
~~~
- message: Downloading Metadata Files
code: sync.downloading.metadata
state: completed
done: 10 <===== downloaded 10 files
~~~
Actual results:
Multiple metadata files downloaded on every sync, consuming bandwidth and resources to process it.
Expected results:
Download all the metadata only if there were changes on the repository, keeping the downloading and processing time to the minimum possible.
Additional info:
A little more background:
Pulp tries to avoid doing this by using a couple of heuristics. In pulp_rpm 3.14 which is shipped with Satellite 6.10, the heuristics were as follows:
* If no repository version has been created since the one created by the last sync
* If the repomd.xml is the same
* If the remote has not been changed since the last sync.
THEN the sync is skipped.
This is fine in isolation, but in the Katello context, the remote is *always* updated just prior to the sync in order to refresh the TLS client certificates. Thus the heuristic is violated and the sync always occurs.

1. Enable any repository (Red Hat Enterprise Linux 8 for x86_64 - BaseOS RPMs was used in testing)
2. Sync it once
3. Sync it again.
Actual results:
10 Files synced the first time, none the next time.
Expected results:
