Erm, well it will until we hit the 5GB Swift chunking limit, anyway.
Do you know what this means (glance/store/swift.py +347)?
Why can't we stream from body_file?
else:
# Write the image into Swift in chunks. We cannot
# stream chunks of the webob.Request.body_file, unfortunately,
# so we must write chunks of the body_file into a temporary
# disk buffer, and then pass this disk buffer to Swift.
Thanks,
Ewan.
