This also adds a check to nova/hacking/checks.py that should check dict.iteritems, dict.itervalues and dict.iterkeys should not be used in the future. NOTE: In _dict_from_object() method of test_db_api.py items() method is called on dict and iteritems() method is called if object is other than dict. Changed it to directly use obj.items as obj can either be dict or object of nova.db.sqlalchemy.models.<Class> and both have items() method.

Guidelines for writing new hacking checks
|
|
|
|
- Use only for Nova specific tests. OpenStack general tests
|
|
should be submitted to the common 'hacking' module.
|
|
- Pick numbers in the range N3xx. Find the current test with
|
|
the highest allocated number and then pick the next value.
|
|
- Keep the test method code in the source file ordered based
|
|
on the N3xx value.
|
|
- List the new rule in the top level HACKING.rst file
|
|
- Add test cases for each new rule to nova/tests/unit/test_hacking.py
