oslo_should be used instead of
Beginning with the Pike series, OpenStack no longer supports log translation. It is not useful to add translation instructions to new code, the instructions can be removed from old code, and the hacking checks that enforced use of special translation markers for log messages have been removed.
Other user-facing strings, e.g. in exception messages, should be translated using
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/user/guidelines.html
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 Manila, please read manila/testing/README.rst.
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 http://wiki.openstack.org/testr

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.
If the change relates to a specific driver (libvirt, xenapi, qpid, etc...), begin the first line of the commit message with the driver name, lowercased, followed by a colon.
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.
