Jan,

Would you please review this BZ and add any notes of what you require?

Thanks,
John

Hi, I think description is correct, implementation as an option sounds good. 

In Conductor we have sw selection UI similar to gpk-application, so when user selects group (group of groups in fact) in the left panel, conductor fetches packagegroups for this group. In retrieved package list are listed packages which are not in repository (for example package 'silo' in 'coreutils' group). When user selects this package, image building fails because of missing package.

Only workaround for now is to fetch all packages (very slow query) to filter only existing pkgs, so filtering on pulp side will be very helpful.

We have modified the package group call on the repositories controller.  The call takes in 2 optional parameters "filter_missing_packages" and/or "filter_incomplete_groups".  


Webservice call:
title: Repository Package Groups
description: Get the package groups in the repositories.
method: GET
path: /repositories/<repository id>/packagegroups/
permission: READ
success response: 200 OK
failure response: 404 Not Found if the id does not match a repository
return: list of package group names
filters:
* filter_missing_packages, bool, True means to filter results to remove missing package names
* filter_incomplete_groups, bool, True means to filter results to remove groups with missing packages


"filter_missing_packages" will return the groups information minus any package names that are not part of this repository.

"filter_incomplete_groups" will return only those groups that all packages listed are in the repository.  (If a group has a package not in the repo, then this group will not be returned in the result).

QE:
Example from pulp-admin using the "-f/--filter" option.

Create two groups.
On first group add a package that exists in the repo
On second group add a package that exists in the repo AND a package name that is made up (not part of the repo)

To test: "filter_missing_packages" you will need to look at 'packagegroup info' on a specific group
 sudo pulp-admin packagegroup info --repoid test_repo --id jwm_group -f

 This should only return package names that are part of the repo



To test: "filter_incomplete_groups" you would run:
 sudo pulp-admin packagegroup list --repoid test_repo -f
 This should only return the first packagegroup, the one that all package names listed are part of the repo.

AND:
  sudo pulp-admin packagegroup list --repoid test_repo
  This should return both packagegroups
