[Bug 1805332] Re: [Swift backend] Upload image hit error: Unicode-objects must be encoded before hashing

[Corey Bryant]

Hello wangxiyuan, or anyone else affected,

Accepted python-glance-store into rocky-proposed. The package will build
now and be available in the Ubuntu Cloud Archive in a few hours, and
then in the -proposed repository.

Please help us by testing this new package. To enable the -proposed
repository:

  sudo add-apt-repository cloud-archive:rocky-proposed
  sudo apt-get update

Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-rocky-needed to verification-rocky-done. If it does
not fix the bug for you, please add a comment stating that, and change
the tag to verification-rocky-failed. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance!

Bug description:
  [Impact]
  If we upload a large image (larger than 1G), the glance_store will hit a Unicode error. To fix this a patch has been merged in upstream master and backported to stable rocky.

  [Test Case]
  Deploy glance related to swift-proxy using the object-store relation. Then attempt to upload a large image (not cirros)

  $ openstack image create --public --file /home/ubuntu/images/bionic-server-cloudimg-amd64.img bionic-test
  500 Internal Server Error: The server has either erred or is incapable of performing the requested operation. (HTTP 500)

  If the patch is manually applied and glance-api restarted then the
  above command succeeds.

  In order to avoid regression of existing consumers, the OpenStack team will
  run their continuous integration test against the packages that are in
  -proposed. A successful run of all available tests will be required before the
  proposed packages can be let into -updates.

  The OpenStack team will be in charge of attaching the output summary of the
  executed tests. The OpenStack team members will not mark ‘verification-done’ until
  this has happened.

  [Regression Potential]
  In order to mitigate the regression potential, the results of the
  aforementioned tests are attached to this bug.

  [Original Description]

  env: master branch, Glance using swift backend.

  We hit a strange error， if we upload a large image (larger than 1G),
  the glance_store will hit a error:Unicode-objects must be encoded
  before hashing. But if the image is small enough, the error won't
  happen.

  error log:
  https://www.irccloud.com/pastebin/jP3DapNy/

  After dig into the code, it appears that when chunk reading the image
  data, the date piece may be non-byte, so the checksum.updating will
  raise the error.

  encoding the date piece to ensure it's byte can solve the problem.
