Description RHOS Integration 2013-12-13 16:47:46 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/oslo/+spec/api-validation-utility.

Description:

This is a feature request to enable openstack-common code in oslo to perform common input validations 
across Openstack API.

Most of the validation of create resource API are scattered and duplicated, across Nova, Keystone, Cinder, Glance. Due to this, there is a lot of inconsistency in how the APIs respond to similar classes of input.

Refer: https://docs.google.com/file/d/0BwufSlaYow2GUUZJVlJYVGM2VVU/edit?usp=sharing

A utility in Oslo will enable common validation tasks such as:
* checking input length (based on min and max values)
* checking input well-formedness (say, based on an expected regex), 
* raise appropriate exceptions wherever needed

This could go into a separate module like openstack/common/validation_utils.py
