[Pki-devel] [PATCH] 100 Refactoring profile.py and fixes a few issues

The attached patch contains the following changes. -- Refactoring profile.py and replacing the usage of property with a dictionary for attribute name conversions(when sending the objects back to server). -- Replace the logic of traversing the dict of NOTYPES with a search in NOTYPES.itervalues for the instance of an object. The traversal method causes an issue in-case of inherited classes as isinstance(cert_review_response, obj)) is true for obj= CertEnrolmentRequest/CertReviewResponse. Since a dict is not an ordered data structure, we cannot traverse it correctly. This creates problems during attr name conversion. This can still be modified by using a Set for NOTYPES and TYPES and adding the class objects to the sets and performing a lookup. Since this requires changes across the python code, i think we should take this up in a separate patch. -- Rewrote the attr_name_conversion method in encoder.py to return a new dict with the changes attribute names rather than make the changes to the object's __dict__. This would allow re-usage of the object. Otherwise an AttributeError will be raised when accessing an attribute. --Abhishek
