Well, at very least in Xena I still do experience issues with uwsgi. It mostly depends on clients though and if they do support chunking properly. For example python-openstackclient works properly, but if you use python-glanceclient with ceph backend, as example, you will hit issues. And other projects, like heat, do still use glanceclient.
Also interoperable import still was not working with uwsgi. I have not tested it on Yoga, but haven't saw patches that was aiming to fix it either.
I think you have also missed to mention neutron, that does not really work with uwsgi and ovn as a ml2 driver. Not sure if that was fixed on Zed, but as of Yoga it was known not to work.
I've heard that it's now fixed with Glance, but I haven't checked the
fact for myself. Has anyone already run Glance (with Swift as backend)
under uwsgi, instead of eventlet? What's the status? Has all of the
remaining issues been tackled?
