Example Spec - The title of your blueprint
|
|
==========================================
|
|
|
|
Include the URL of your launchpad blueprint:
|
|
|
|
https://blueprints.launchpad.net/python-cratonclient/+spec/example
|
|
|
|
Introduction paragraph -- why are we doing anything? A single paragraph of
|
|
prose that operators can understand.
|
|
|
|
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/python-cratonclient/+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:
|
|
https://www.siafoo.net/reST.xml
|
|
|
|
* 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.

Problem description
|
|
===================
|
|
|
|
A detailed description of the problem:
|
|
|
|
* For a new feature this might be use cases. Ensure you are clear about the
|
|
actors in each use case: End User vs Deployer
|
|
|
|
* For a major reworking of something existing it would describe the
|
|
problems in that feature that are being addressed.
|
|
|
|
|
|
Proposed change
|
|
===============
|
|
|
|
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?
|
|
|
|
Alternatives
|
|
------------
|
|
|
|
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.
|
|
|
|
|
|
Security impact
|
|
---------------
|
|
|
|
Describe any potential security impact on the system. Some of the items to
|
|
consider include:
|
|
|
|
* Does this change touch sensitive data such as tokens, keys, or user data?
|
|
|
|
* Does this change involve cryptography or hashing?
|
|
|
|
* Does this change require the use of sudo or any elevated privileges?
|
|
|
|
* Does this change involve using or parsing user-provided data? This could
|
|
be directly at the API level or indirectly such as changes to a cache layer.
|
|
|
|
* Can this change enable a resource exhaustion attack, such as allowing a
|
|
single API interaction to consume significant server resources? Some examples
|
|
of this include launching subprocesses for each connection, or entity
|
|
expansion attacks in XML.
|
|
|
|
For more detailed guidance, please see the OpenStack Security Guidelines as
|
|
a reference (https://wiki.openstack.org/wiki/Security/Guidelines). These
|
|
guidelines are a work in progress and are designed to help you identify
|
|
security best practices. For further information, feel free to reach out
|
|
to the OpenStack Security Group at openstack-security@lists.openstack.org.
|
|
|
|
Other end user impact
|
|
---------------------
|
|
|
|
Aside from the API, are there other ways a user will interact with this
|
|
feature?
|
|
|
|
Performance Impact
|
|
------------------
|
|
|
|
Describe any potential performance impact on the system. How often will new
|
|
code be called? Is there a major change to the calling pattern of existing
|
|
code?
|
|
|
|
Examples of things to consider here include:
|
|
|
|
* A small change in a utility function or a commonly used decorator can have a
|
|
large impact on performance.
|
|
|
|
* Calls which result in database queries can have a profound impact on
|
|
performance when called in critical sections of the code.
|
|
|
|
* Will the change include any locking, and if so what considerations are there
|
|
on holding the lock?
|
|
|
|
Developer impact
|
|
----------------
|
|
|
|
Discuss things that will affect other developers working on OpenStack,
|
|
such as:
|
|
|
|
* If the blueprint proposes a change to the store API, discussion of how
|
|
stores would implement the feature is required.
|
|
|
|

Implementation
|
|
==============
|
|
|
|
Assignee(s)
|
|
-----------
|
|
|
|
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.
|
|
|
|
Primary assignee:
|
|
- <launchpad-id or None>

|
|
Work Items
|
|
----------
|
|
|
|
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.
|
|
|
|
|
|
Dependencies
|
|
============
|
|
|
|
* Include specific references to specs and/or blueprints in
|
|
python-cratonclient, or in other
|
|
projects, that this one either depends on or is related to.
|
|
|
|
* If this requires functionality of another project that is not currently used
|
|
by python-cratonclient: document that fact.
|
|
|
|
* Does this feature require any new library dependencies or code otherwise not
|
|
included in OpenStack? Or does it depend on a specific version of library?
|
|
|
|
|
|
Testing
|
|
=======
|
|
|
|
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)? If so, are there mitigation plans (3rd
|
|
party testing, gate enhancements, etc).
|
|
|
|
|
|
Documentation Impact
|
|
====================
|
|
|
|
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.
|
|
|
|
|
|
