issue seems to be: having already a promotion passed and making a second try to the same org/env (but different promotion name).

I've reproduced this problem, when the first promotion was made prior to synchronization. It seems Pulp ends up then with the following error:

However, there is no error showed on the Katello side. This error prevents creation of an association between repo and it's clone in Pulp (all clone_ids are empty, even if the cloned repos are already there).

Due to missing this association, Katello is not aware of the existing clone and tries to clone it again in next promotion. This causes the validation error on pulp_id (because a record is aready created from the previous try)

*** Bug 765962 has been marked as a duplicate of this bug. ***

The bug above is not a duplicate of this one

Two issues:

1) We do not report error when an async task fails. We need to properly report those errors in Katello.

2) We should not allow to promote an empty repo.

Working on the 2)

Taking the 1)

Number 1 fixed in version katello-0.1.139-1

commit 1542d8c21802b56b79a102685a38c9f6c23f2661
async tasks - raising exception when a task fails while waiting until it finishes

Waiting for number 2.

Note to myself: empty repo is UNSYNCHRONIZED repo in this context.

Empty repo is okay: http://lzap.fedorapeople.org/fakerepos/empty/

   def add_product cpid
     product = find_product_by_cpid(cpid)
+
+    # check if product was already synced
+    raise _("Product '#{product.name}' was not synchronized yet") if product.last_sync.nil?
+
     self.products << product
     product
   end


0f5c9f7 765888 - Error during promotion

The problem with repositories not being promoted before synchronization relates to the bug on Pulp side:

https://bugzilla.redhat.com/show_bug.cgi?id=760310

With the fix on the Pulp side there is no need to check the sync status before promotion.

Ok I will revert the patch as it was fixed in Pulp.

    Revert "765888 - Error during promotion"

# VERIFIED

Trying with scenarios of import manifest/sync repo/promoting, re-promoting content - all works fine so far.

Please fill free to reopen this bug or another defect related to the Red Hat provider's manifest import/sync/promotion.

As an CDN was used: http://inecas.fedorapeople.org/fakerepos/cds/ (and the fake -manifest-syncable.zip)

a note: promoting empty repos is allowed and is ok now.
