Pulp

• Create a repo
• upload a package -> this should generate version 1
• remove a package -> this should generate version 2
• optionally upload another package -> this should generate version 3
• Now export version 1
• copy and extract the generated tar gz

$ cat pulpcore.app.modelresource.RepositoryResource.json
[{"pulp_type": "rpm.rpm", "name": "life-531063", "description": "", "next_version": 4, "remote": ""}]

• do an ls

$ ls|grep repo
repository-life-531063_1

so notice that next version is pointing to 4 while the directory name ends with _1

• Now wipe the db
• Create a new yum repository called foo
• Create an importer with the mapping -> {'foo':"life-531063"}
• Try to import the exported tgz
• The operation should fail
• You should see an error along the lines of

• The logic for this error is here -> https://github.com/pulp/pulpcore/blob/master/pulpcore/app/tasks/importer.py#L71-L74 . The code looks for repository-life-531063_3 when it should be looking at repository-life-531063_1

Not sure if its the importer's fault or exporter's. But we definitely need to be able to handle this.
