Installing oslo.rootwrap from pypi hides oslo.* installed as editable

This is fixed in:
http://git.openstack.org/cgit/openstack/oslo.rootwrap/commit/?id=4c499d366429f68ff29c7a2f93553b06f3697405

I just need to cut a new release so that Pypi looks good too. Will do once https://review.openstack.org/#/c/69033 merges.

Given that the failure is 100% reproduceable in devstack, how did the gate check pass for the nova commit in question?

Because the gate runs from the master branch.

so in my environment i have the following in my /usr/local/lib/python2.7/dist-packages space:
oslo/
oslo.config-1.2.0a3-py2.7-nspkg.pth
oslo.messaging.egg-link
oslo.config-1.2.0a3-py2.7.egg-info/
oslo.config.egg-link
oslo.rootwrap.egg-link

i have the above patch but i still get the rootwrap.cmd importerror shown here: https://answers.launchpad.net/devstack/+question/242879

do i need to clean something before this should work for me? i'm not using pypi package (or at least i don't think i am)

1.1.0 is on Pypi now, it should fix the issue. please report here if it doesn't.

master works for me. for reference, in case anyone runs into same issue i had, i had to remove stray oslo.config-1.2.0a3-py2.7.egg-info package for it to work.

How to make this work on f20? It does not work .. tried to install oslo-rootwrap as suggested but encountering the same issue...

FORCE=yes ./stack.sh throws this error...

Let's try that again:

I'm afraid the 1.1.0 release of oslo.rootwrap on pypi has not solved the problem. As before, oslo/__init__.py does not get deployed, despite appearing in the distribution file. If you manually install it in a venv on a devstack-provisioned host, can you reproduce this behaviour?

The __init__.py file for a namespace package isn't supposed to be installed.

I can't reproduce this problem. Can you post your localrc and any other configuration for devstack that you're using?

Hmm, I see now that the installation deliberately skips installation of the namespace package's init module. I was confused by the fact that manually touching that file seems to fix the problem I'm seeing. As per the bug description, it appears that installing one namespace package as non-editable precludes installing other packages in the same namespace as editable. Can you reproduce the problem with the script that follows?

#/bin/bash -eux
sudo apt-get install -y git python-pip python-virtualenv
virtualenv /tmp/foo_env
cd /tmp/foo_env
git clone https://github.com/openstack/oslo.config.git
. bin/activate
pip install --editable oslo.config
pip install oslo.rootwrap
python -c 'import oslo.config'

It turns out my problem was environment-specific. I use a local mirror for git repos and oslo.rootwrap was missing. Devstack doesn't stop when a git checkout fails, so oslo.rootwrap wasn't installed from source and was subsequently installed by nova from pypi.

The oslo.config version that came with my Ubuntu was 1.2.1, which had this same error. Check it with:

root@controller:~# pip search oslo.config
oslo.config - Oslo Configuration API
  INSTALLED: 1.2.1
  LATEST: 1.4.0.0a5

So, what I did was to update it with:

pip --upgrade oslo.config

Then, check:

root@controller:~# pip search oslo.config
oslo.config - Oslo Configuration API
  INSTALLED: 1.3.0
  LATEST: 1.4.0.0a5

And with this, the command finally succeeded in its execution. Hope this helps!

UPDATE-WARNING: although what I posted helps executing the glance-manage db_sync command, from then on I haven't been able to anything with glance, as I always get the same error:

root@controller:~# glance image-list
'Discover' object has no attribute 'url_for'

Tried installing openstack and it led me to this bug.

Can't start nova-api.

Removed all /usr/local/lib/python2.7/dist-packages/oslo*

Copied /usr/local/lib/python2.7/dist-packages/novaclient from my earlier installations.

Then restarted nova-api. It worked.

Running below command fixed with updated patch.

pip install oslo.rootwrap --upgrade
