Open Stack

I just wanted to send a quick note about the recent oslo.policy release 
which may impact some projects.  Some new functionality was added that 
allows a context object to be passed in to the enforcer directly, but as 
part of that we added a check that the type of the object passed in was 
valid for use.  This caused an issue in Glance's unit tests because they 
were mocking the context object and a Mock object didn't pass the type 
check.  This was fixed in [1], but if any other projects have a similar 
pattern in their unit tests it is possible it may affect them as well.

If you do run into any issues with this, please contact the Oslo team in 
#openstack-oslo or with the [oslo] tag on the mailing list so we can 
help resolve them.  Thanks.
