Description

  1. Problem statement

The general context of this issue is that we have a few Deb repos managed by pulp and we'd like to use apt pinning client-side (https://wiki.debian.org/AptPreferences) to control the priorities of the various repos.

The problem is that apt pinning works by distinguishing the repos based on the information present in each repo metadata file and the metadata produced by pulp_deb effectively uses the codename across the board for all the metadata fields, thus preventing apt pinning.

Here is an example of a Release file (the repo metadata file) produced by pulp_deb (this is version 1.7.1 but looking at the code, current master works the same):

# head -n 10 /var/lib/pulp/published/deb/master/deb_distributor/upstream_ubuntu-xenial-security_all/1529937308.62/dists/xenial/Release
Architectures: amd64
Components: restricted main universe
Codename: xenial
Suite: xenial
Description: Xenial
Origin: Xenial
Label: Xenial
Version: 1.0

Here is a "proper" Release file from http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu/dists/xenial/Release

[...]

The main problem is that, in the Release file generated by pulp, the value for 'Label' and 'Origin' which are typically used to pin repositories, are both 'xenial'/'Xenial' (i.e. the codename) and not something meaningful which allows to distinguish repos.

  1. Suggested solution

Since it's not entirely clear where to get the 'Origin' information I suggest simply fixing the 'Label' by setting it to the repo id: this will enable us to do pinning. Additionally, the 'Description' field can also be fixed.

Fix repo metadata information

Fix the 'Label' and the 'Description' in the repo metadata ('Release' file). This enables Apt Pinning because pinning uses this metadata to distinguish between repos.
