Pulp

https://github.com/pulp/pulp/pull/2340

Steps to reproduce:

This assumes you already have a nodes setup and the child node is named: child.

1. Create a small test repository on the parent node using the attached https://pulp.plan.io/attachments/download/189/test-repo.tar.

$ cd /tmp
$ untar test-repo.tar
# cd test
$ createrepo .
$ modifyrepo --mdtype=productid productid repodata

1. Create a pulp repository and sync it with the test repo.

$ pulp-admin rpm repo create --repo-id=test --feed=file:///tmp/test
$ pulp-admin node enable --repo-id=test
$ pulp-admin rpm repo sync run --repo-id=test

1. Bind (node) the child node to the repository.

$ pulp-admin node bind --repo-id=test --node-id=child

1. Do a node sync.

$ pulp-admin node sync run --node-id=child

1. Make sure the sync succeeds!

1. Edit the productid and update the repository.

$ cd /tmp/test
$ echo "product: 3000-xxxxxxx" > productid
$ rm packages/vim-enhanced-7.4.475-2.fc20.x86_64.rpm
$ createrepo .
$ modifyrepo --mdtype=productid productid repodata

1. Re-sync the pulp repository with changed upstream.

   $ pulp-admin rpm repo sync run --repo-id=test
   

1. Do another node sync. This is where the error occurred.

   $ pulp-admin node sync run --node-id=child
