Hi everyone I would like to point out the bp https://blueprints.launchpad.net/swift/+spec/authorization-policy to may be have some early feedback from the community. I have submitted a first patch which I hope will serves as an example/base for discussion. Specially I was wondering what would be the best way to integrate the policy engine (or not) within swift. For now I have roughly adapted the policy engine found here (https://github.com/openstack/oslo-incubator/blob/master/openstack/common/policy.py) and I removed all the unnecessary dependencies to modules like oslo.config, log, etc, and finally kept only the parts that deal with parsing and rule checking, but any advice in this (or more globally) would be highly appreciated.
