Ec2api Style Commandments ========================= - Step 1: Read the OpenStack Style Commandments https://github.com/openstack-dev/hacking/blob/master/doc/source/index.rst - Step 2: Read on Ec2api Specific Commandments ---------------------------- General ------- - Do not use locals(). Example:: LOG.debug("volume %(vol_name)s: creating size %(vol_size)sG" % locals()) # BAD LOG.debug("volume %(vol_name)s: creating size %(vol_size)sG" % {'vol_name': vol_name, 'vol_size': vol_size}) # OKAY - Use 'raise' instead of 'raise e' to preserve original traceback or exception being reraised:: except Exception as e: ... raise e # BAD except Exception: ... raise # OKAY Creating Unit Tests ------------------- For every new feature, unit tests should be created that both test and (implicitly) document the usage of said feature. If submitting a patch for a bug that had no unit test, a new passing unit test should be added. If a submitted bug fix does have a unit test, be sure to add a new one that fails without the patch and passes with the patch. For more information on creating unit tests and utilizing the testing infrastructure in OpenStack Ec2api, please read ec2api/testing/README.rst.
