==========================================
|
||||
Example Spec - The title of your blueprint
|
||||
==========================================
|
||||
|
||||
Include the URL of your launchpad blueprint:
|
||||
|
||||
https://blueprints.launchpad.net/ceilometer-powervm/+spec/example
|
||||
|
||||
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:
|
||||
|
||||
* The aim of this document is first to define the problem we need to solve,
|
||||
and second agree the overall approach to solve that problem.
|
||||
|
||||
* You should aim to get your spec approved before writing your code.
|
||||
While you are free to write prototypes and code before getting your spec
|
||||
approved, its possible that the outcome of the spec review process leads
|
||||
you towards a fundamentally different solution than you first envisaged.
|
||||
|
||||
* 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: https://blueprints.launchpad.net/ceilometer-powervm/+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 and see the generated
|
||||
HTML file in doc/build/html/specs/<path_of_your_file>
|
||||
|
||||
* 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. What problem is this blueprint
|
||||
addressing?
|
||||
|
||||
|
||||
Use Cases
|
||||
---------
|
||||
|
||||
What use cases does this address? What impact on actors does this change have?
|
||||
Ensure you are clear about the actors in each use case: Developer, End User,
|
||||
Deployer etc.
|
||||
|
||||
|
||||
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.
|
||||
|
||||
|
||||
End user impact
|
||||
---------------
|
||||
|
||||
How would the end user be impacted by this change? The "End User" is defined
|
||||
as the users of the deployed cloud?
|
||||
|
||||
|
||||
Performance Impact
|
||||
------------------
|
||||
|
||||
Describe any potential performance impact on the system, for example
|
||||
how often will new code be called, and 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 impacts on performance.
|
||||
|
||||
* Will the change include any locking, and if so what considerations are there
|
||||
on holding the lock?
|
||||
|
||||
|
||||
Deployer impact
|
||||
---------------
|
||||
|
||||
Discuss things that will affect how you deploy and configure OpenStack
|
||||
that have not already been mentioned, such as:
|
||||
|
||||
* What config options are being added? Are the default values ones which will
|
||||
work well in real deployments?
|
||||
|
||||
* Is this a change that takes immediate effect after its merged, or is it
|
||||
something that has to be explicitly enabled?
|
||||
|
||||
* If this change is a new binary, how would it be deployed?
|
||||
|
||||
* Please state anything that those doing continuous deployment, or those
|
||||
upgrading from the previous release, need to be aware of. Also describe
|
||||
any plans to deprecate configuration values or features.
|
||||
|
||||
|
||||
Developer impact
|
||||
----------------
|
||||
|
||||
Discuss things that will affect other developers working on the driver or
|
||||
OpenStack in general.
|
||||
|
||||
|
||||
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>
|
||||
|
||||
Other contributors:
|
||||
<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/blueprints in ceilometer-powervm, or
|
||||
in other projects, that this one either depends on or is related to. For
|
||||
example, a dependency on pypowervm changes should be documented here.
|
||||
|
||||
* If this requires functionality of another project that is not currently used
|
||||
by ceilometer-powervm 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 the important scenarios needed to test here, as well as
|
||||
specific edge cases we should be ensuring work correctly. For each
|
||||
scenario please specify if this requires specialized hardware, a full
|
||||
openstack environment, etc.
|
||||
|
||||
Please discuss how the change will be tested. We especially want to know what
|
||||
functional tests will be added. It is assumed that unit test coverage will be
|
||||
added so that doesn't need to be mentioned explicitly.
|
||||
|
||||
|
||||
Documentation Impact
|
||||
====================
|
||||
|
||||
Which audiences are affected most by this change, and which documentation
|
||||
titles should be updated because of this change? Don't repeat details
|
||||
discussed above, but reference them here in the context of documentation
|
||||
for multiple audiences.
|
||||
|
||||
|
||||
References
|
||||
==========
|
||||
|
||||
Please add any useful references here. You are not required to have any
|
||||
