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

[Łukasz Zemczak]

SRU template is available in comment #8. Moved it into the description
and proceeding with upload review.

** Description changed:

+ [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]
+ 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.

  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.

** Changed in: python-glance-store (Ubuntu Disco)
       Status: Incomplete => In Progress
