glance-simplestreams-sync installs simplestreams from ppa:cloud-installer/simplestreams-testing

Hi Felipe, thanks for tracking this down, and my apologies for the problem. The PPA exists because of bug https://bugs.launchpad.net/simplestreams/+bug/1340983 -- the fix for which was merged in simplesteams 0.1.0~bzr354-0ubuntu1 , but trusty still only has version 0.1.0~bzr341-0ubuntu2.4

The missing feature is providing the ability to get progress updates on long downloads, which is used in the openstack installer.

Merging this branch will break that feature for any users of the openstack installer on trusty - it will simply degrade to showing no progress and no completion notification for sync'd images.

Ideally we could get that change for simplestreams backported into trusty so this important fix can go through without breaking anything.

Please hold off merging this until we can talk to Scott and come up with reasonable way to address this (possibly backporting simplestreams)

Here is the relevant code that went into the package in our ppa:

Also, just for completeness and because it confused me - the PPA should be added by both trunk and next/ versions of the charm:

next:

http://bazaar.launchpad.net/~openstack-charmers/charms/trusty/glance-simplestreams-sync/next/view/head:/hooks/hooks.py#L201

trunk:

http://bazaar.launchpad.net/~openstack-charmers/charms/trusty/glance-simplestreams-sync/trunk/view/head:/hooks/hooks.py#L208

Felipe - are you seeing different behavior?

I understand that you'll lose a feature, but IIRC the cloud-installer
allows users to choose ceph-radosgw to provide the object-store
service, if that's the case, then that use case is also broken.

Did you try to request an SRU?, I understand this is a feature and it
doesn't fit into SRU's definition, but considering this important for
our users maybe an exception could be granted.

Felipe, I'm planning to SRU that. Scott Moser has let me know that he'd sponsor it.

Thanks Mike, I really appreciate it. I'll set back my MP to 'work in
progress' until your SRU lands into trusty-updates.
