[Bug 1657459] Re: WebOb>=1.2.3 requirement for Glance will lead to 0 bytes backing image files on OpenStack Newton, although the image file sent to the python client does not have 0 bytes

[Corey Bryant]

Hi Phil, I lowered the glance (Ubuntu) package importance to low, which
makes sense since we're locked into a single version for ocata in ubuntu
(webob 1.6.2). However for the upstream bug I think your're right.  I
can't change the importance of the upstream bug, but likely it should be
updated.

  WebOb>=1.2.3 requirement for Glance will  lead to 0 bytes backing

Bug description:
  On CentOS 7 AIO Newton OpenStack deployed with packstack, the default
  WebOb glance requirement was >= 1.2.3 and pip installed the 1.7.0
  version.

  When I created a glance image from the cli, using the filesystem
  backend as default, with a raw file of 1GB, the glance image-create
  command showed that a image was created, but with the size of 0 bytes.

  After forcing with pip the WebOb==1.2.3 version, the issue was not
  longer there.

  I have tried with python 2.7 and 3.4 and to upload the image via
  horizon or with different python-glance client versions => when WebOb
  version was 1.7.0 the outcome was wrong, as I ended up with a 0 bytes
  image in the backing store.
