Title:
libvirt imagebackend cache code encapsulation needs refactoring
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
libvirt.imagebackend.cache needs to be refactored to eliminate the
callback to call_if_not_exists(). The only way it could meet all the
requirements while remaining a callback is if the os.path.exists()
check were removed from the function, which would then require path
checks in each of the backend classes where prepare_template() is
called. Ultimately, this is a lot more code than simply adding a
backend-specific call to each class.
There's too much risk associated with such a refactor at such a late
stage for Grizzly, so we'll look to tackle this for Havana.
