Include the URL of your launchpad blueprint:
Introduction paragraph – why are we doing anything? A single paragraph of prose that operators can understand. The title and this first paragraph should be used as the subject line and body of the commit message respectively.
Some notes about using this template:
Your spec should be in ReSTructured text, like this template.
Please wrap text at 79 columns.
The filename in the git repository should match the launchpad URL, for example a URL of: https://blueprints.launchpad.net/sahara/+spec/awesome-thing should be named awesome-thing.rst
Please do not delete any of the sections in this template. If you have nothing to say for a whole section, just write: None
For help with syntax, see http://sphinx-doc.org/rest.html
To test out your formatting, build the docs using tox, or see: http://rst.ninjs.org
If you would like to provide a diagram with your spec, ascii diagrams are required. http://asciiflow.com/ is a very nice tool to assist with making ascii diagrams. The reason for this is that the tool used to review specs is based purely on plain text. Plain text will allow review to proceed without having to look at additional files which can not be viewed in gerrit. It will also allow inline feedback on the diagram itself.
If your specification proposes any changes to the Sahara REST API such as changing parameters which can be returned or accepted, or even the semantics of what happens when a client calls into the API, then you should add the APIImpact flag to the commit message. Specifications with the APIImpact flag can be found with the following query:
A detailed description of the problem:
Here is where you cover the change you propose to make in detail. How do you propose to solve this problem?
If this is one part of a larger effort make it clear where this piece ends. In other words, what’s the scope of this effort?
What other ways could we do this thing? Why aren’t we using those? This doesn’t have to be a full literature review, but it should demonstrate that thought has been put into why the proposed solution is an appropriate one.
Changes which require modifications to the data model often have a wider impact on the system. The community often has strong opinions on how the data model should be evolved, from both a functional and performance perspective. It is therefore important to capture and gain agreement as early as possible on any proposed changes to the data model.
Questions which need to be addressed by this section include:
Each API method which is either added or changed should have the following
Aside from the API, are there other ways a user will interact with this feature?
Discuss things that will affect how you deploy and configure OpenStack that have not already been mentioned, such as:
Discuss things that will affect other developers working on OpenStack, such as:
Does it require changes to the sahara-image-elements? If so, changes should be described well.
Does it require changes to the sahara-dashboard / horizon? If so, changes should be described well. If it’s about complex changes than probably a separate blueprint / spec should be created for it.
Who is leading the writing of the code? Or is this a blueprint where you’re throwing it out there to see who picks it up?
If more than one person is working on the implementation, please designate the primary author and contact.
Work items or tasks – break the feature up into the things that need to be done to implement it. Those parts might end up being done by different people, but we’re mostly trying to understand the timeline for implementation.
Please discuss how the change will be tested. We especially want to know what tempest tests will be added. It is assumed that unit test coverage will be added so that doesn’t need to be mentioned explicitly, but discussion of why you think unit tests are sufficient and we don’t need to add more tempest tests would need to be included.
Is this untestable in gate given current limitations (specific hardware / software configurations available)? Is this untestable in sahara-ci? If so, are there mitigation plans (3rd party testing, gate enhancements, etc).
What is the impact on the docs team of this change? Some changes might require donating resources to the docs team to have the documentation updated. Don’t repeat details discussed above, but please reference them here.
Please add any useful references here. You are not required to have any reference. Moreover, this specification should still make sense when your references are unavailable. Examples of what you could include are:
