Description Pavel Moravec 2017-09-14 10:48:30 UTC
Description of problem:
Having an empty repository in a Content View and publishing this C.V. or promoting to a L.E., an (automated) attempt to synchronize the C.V. content fails on trying to sync this empty repo with error:

PulpCodedException: Error retrieving metadata: NOT FOUND

Also manual Capsule sync fails the same way.

This situation (empty repo in a C.V.) can happen due to various legitimate reasons and shouldnt be dealt as a user/config error.

Root cause behind this bug: the empty repo is never published on Satellite. Because step Actions::Pulp::Repository::DistributorPublish is called with "matching_content: true" - since previously published content (empty) matches current content (empty).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
0. Satellite with a Capsule in Library environment
1. Have a repo with 1 package
2. Add the repo to a Content View and use filter to exclude the package
3. Publish the repo
4. Check task Actions::Katello::ContentView::CapsuleGenerateAndSync triggered on background
5. Try to sync the Cpasule manually

Actual results:
4. and 5. fails with error

PulpCodedException: Error retrieving metadata: NOT FOUND

on the empty repo

Expected results:
No such error

Additional info:

Comment 2 Pavel Moravec 2017-09-14 11:33:19 UTC
(not sure if my explanation behind matching_content is correct, but simply I see matching_content=true and hence also matching_content_skip=true in Actions::Pulp::Repository::DistributorPublish, and no repo publish called)

Build: Satellite 6.3.0 snap26

Verification steps:

1) External capsule with "Empty" lifecycle Env
2) CV with empty content , which used filter to exclude all packages
3) Synced the CV with library env 
4) promoted the CV to "Empty" Lifecycle Env
5) Actions::Katello::ContentView::CapsuleGenerateAndSync was triggered
6) The task was successful

Task Result:
Id: eaaeaa63-bf96-48d3-acb5-cb4cda5c85ec

Label: Actions::Katello::ContentView::CapsuleGenerateAndSync
