Cloudkitty Style Commandments
=============================
- Step 1: Read the OpenStack Style Commandments
https://docs.openstack.org/hacking/latest
- Step 2: Read on
Cloudkitty Specific Commandments
--------------------------------
- [C310] Check for improper use of logging format arguments.
- [C311] Use assertIsNone(...) instead of assertEqual(None, ...).
- [C312] Use assertTrue(...) rather than assertEqual(True, ...).
- [C313] Validate that logs are not translated.
- [C314] str() and unicode() cannot be used on an exception.
Remove or use six.text_type().
- [C315] Translated messages cannot be concatenated. String should be
included in translated message.
- [C317] `oslo_` should be used instead of `oslo.`
- [C318] Must use a dict comprehension instead of a dict constructor
with a sequence of key-value pairs.
- [C319] Ensure to not use xrange().
- [C320] Do not use LOG.warn as it's deprecated.
- [C321] Ensure that the _() function is explicitly imported to ensure
proper translations.
LOG Translations
----------------
LOG.debug messages will not get translated. Use ``_LI()`` for
``LOG.info``, ``_LW`` for ``LOG.warning``, ``_LE`` for ``LOG.error``
and ``LOG.exception``, and ``_LC()`` for ``LOG.critical``.
``_()`` is preferred for any user facing message, even if it is also
going to a log file. This ensures that the translated version of the
message will be available to the user.
The log marker functions (``_LI()``, ``_LW()``, ``_LE()``, and ``_LC()``)
must only be used when the message is only sent directly to the log.
Anytime that the message will be passed outside of the current context
(for example as part of an exception) the ``_()`` marker function
must be used.
A common pattern is to define a single message object and use it more
than once, for the log call and the exception. In that case, ``_()``
must be used because the message is going to appear in an exception that
may be presented to the user.
For more details about translations, see
https://docs.openstack.org/oslo.i18n/latest/
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.
Running Tests
-------------
The testing system is based on a combination of tox and testr. If you just
want to run the whole suite, run `tox` and all will be fine. However, if
you'd like to dig in a bit more, you might want to learn some things about
testr itself. A basic walkthrough for OpenStack can be found at
https://wiki.openstack.org/wiki/Testr

Commit Messages
---------------
Using a common format for commit messages will help keep our git history
readable. Follow these guidelines:
First, provide a brief summary (it is recommended to keep the commit title
under 50 chars).
The first line of the commit message should provide an accurate
description of the change, not just a reference to a bug or
blueprint. It must be followed by a single blank line.
Following your brief summary, provide a more detailed description of
the patch, manually wrapping the text at 72 characters. This
description should provide enough detail that one does not have to
refer to external resources to determine its high-level functionality.
Once you use 'git review', two lines will be appended to the commit
message: a blank line followed by a 'Change-Id'. This is important
to correlate this commit with a specific review in Gerrit, and it
should not be modified.
For further information on constructing high quality commit messages,
and how to split up commits into a series of changes, consult the
project wiki:
