Size of created image is 0 - no image data is sent

[Kamil Madac]

I'm trying to install OpenStack Newton from sources and I'm not able to successfully upload/create Cirros image:

openstack image create --container-format bare --disk-format qcow2 --file /app/cirros.img --public cirros

Everyting looks OK, except the fact that size of image is 0

When I look into glance filesystem, the file size is 0:

ls -la 0419ce1b-2165-48e5-a37e-c39436babddd

I found out that chunking doesn't work for some reason. I fixed the problem by patching /usr/local/lib/python2.7/dist-packages/glanceclient/common/http.py

After further investigation, root cause of a problem is WebOB 1.7.0 incompatibility with Glance in Newton. Bug is reported here - https://bugs.launchpad.net/glance/+bug/1657459.

More description and discussion about incompatibility can be found here - https://github.com/Pylons/webob/issues/307

After downgrade of WebOB to 1.6.0 on Glance side I can successfully upload new image.
