We have a couple of hacking checks that are specific to Cinder that were written a while back. Unfortunately, when they were written the numbering scheme for hacking checks was not understood. We used N3xx when we should have used C3xx. This patch corrects that mistake. Change-Id: Ia17797005d444ab53a45b47b80b97799114001ee Closes-bug: 1440833

Cinder Style Commandments
|
|
=========================
|
|
|
|
- Step 1: Read the OpenStack Style Commandments
|
|
http://docs.openstack.org/developer/hacking/
|
|
- Step 2: Read on
|
|
|
|
Cinder Specific Commandments
|
|
----------------------------
|
|
- [N314] Check for vi editor configuration in source files.
|
|
- [N319] Validate that debug level logs are not translated
|
|
- [N322] Ensure default arguments are not mutable.
|
|
- [N323] Add check for explicit import of _() to ensure proper translation.
|
|
- [N327] assert_called_once is not a valid Mock method.
|
|
- [N328] LOG.info messages require translations `_LI()`.
|
|
- [N329] LOG.exception and LOG.error messages require translations `_LE()`.
|
|
- [N330] LOG.warning messages require translations `_LW()`.
|
|
- [N333] Ensure that oslo namespaces are used for namespaced libraries.
|
|
- [C301] timeutils.utcnow() from oslo_utils should be used instead of datetime.now().
|
|
- [C302] six.text_type should be used instead of unicode
|
|
- [C303] Ensure that there are no 'print()' statements in code that is being committed.
|
|
- [C304] Enforce no use of LOG.audit messages. LOG.info should be used instead.
|
|
- [C305] Prevent use of deprecated contextlib.nested.
|
|
|
|
|
|
General
|
|
-------
|
|
- 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.
|
|
|
|
Cinder is transitioning to use mock, rather than mox, and so new tests should
|
|
use mock only.
|
|
|
|
For more information on creating unit tests and utilizing the testing
|
|
infrastructure in OpenStack Cinder, please read the Cinder testing
