Many thanks to the OpenStack Nova team for the Example Spec that formed the
|
||||
basis for this document.
|
||||
|
||||
=======================
|
||||
StarlingX: Example Spec
|
||||
=======================
|
||||
|
||||
Some notes about the Spec process:
|
||||
|
||||
* The aim of this document is first to define the problem we need to solve, and
|
||||
second agree on the overall approach to solve that problem.
|
||||
|
||||
* This is not intended to be extensive documentation for a new feature. For
|
||||
example, there is no need to specify the exact configuration changes, nor the
|
||||
exact details of any DB model changes. But you should still define that such
|
||||
changes are required, and be clear on how that will affect upgrades.
|
||||
|
||||
* 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.
|
||||
|
||||
* But, API changes are held to a much higher level of scrutiny. As soon as an
|
||||
API change merges, we must assume it could be in production somewhere, and as
|
||||
such, we then need to support that API change forever. To avoid getting that
|
||||
wrong, we do want lots of details about API changes upfront.
|
||||
|
||||
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 include the StoryBoard number and
|
||||
name, for example a Story at
|
||||
https://storyboard.openstack.org/#!/story/1234567 should be named
|
||||
[category]_1234567-feature-name.rst (refer to instructions.rst for guidelines
|
||||
on a suitable category name)
|
||||
|
||||
* 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.
|
||||
|
||||
|
||||
Example Spec - The title of your blueprint
|
||||
==========================================
|
||||
|
||||
Include the URL of your Storyboard Story:
|
||||
|
||||
Storyboard:
|
||||
https://storyboard.openstack.org/#!/story/list?status=active&project_group_id=86
|
||||
|
||||
Introduction paragraph -- why are we doing anything? The essential "Why" or
|
||||
motivation is key to laying the ground for the work ahead. It provides contexts
|
||||
for all involved in the work. 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.
|
||||
|
||||
Problem description
|
||||
===================
|
||||
|
||||
A detailed description of the problem. What problem is this spec addressing?
|
||||
|
||||
Use Cases
|
||||
---------
|
||||
|
||||
What use cases does this address? What impact on actors does this change have?
|
||||
Ensure you are clear about the actors/personas 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?
|
||||
|
||||
At this point, if you would like to just get feedback on if the problem and
|
||||
proposed change fit in StarlingX, you can stop here and post this for review to
|
||||
get preliminary feedback. If so please say: Posting to get preliminary feedback
|
||||
on the scope of this spec.
|
||||
|
||||
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.
|
||||
|
||||
Data model impact
|
||||
-----------------
|
||||
|
||||
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 should include:
|
||||
|
||||
* What new data objects and/or database schema changes is this going to
|
||||
require?
|
||||
|
||||
* What database migrations will accompany this change.
|
||||
|
||||
* How will the initial set of new data objects be generated.
|
||||
|
||||
REST API impact
|
||||
---------------
|
||||
|
||||
Each API method which is either added or changed should have the following
|
||||
|
||||
* Specification for the method : As best as can be determined at the definition
|
||||
stage.
|
||||
|
||||
* Parameters which can be passed via the url
|
||||
|
||||
* Example use case including typical API samples for both data supplied by the
|
||||
caller and the response
|
||||
|
||||
* Discuss any policy changes, and discuss what things a deployer needs to think
|
||||
about when defining their policy.
|
||||
|
||||
Note that the schema should be defined as restrictively as possible. Parameters
|
||||
which are required should be marked as such and only under exceptional
|
||||
circumstances should additional parameters which are not defined in the schema
|
||||
be permitted (eg additionaProperties should be False).
|
||||
|
||||
Reuse of existing predefined parameter types such as regexps for passwords and
|
||||
user defined names is highly encouraged.
|
||||
|
||||
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 alter the API in a way that may impact security, such as a
|
||||
new way to access sensitive information or a new way to login?
|
||||
|
||||
* 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?
|
||||
|
||||
* Does this change have an impact on python-client? What does the user
|
||||
interface there look like?
|
||||
|
||||
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 periodic task might look like a small addition but if it calls conductor or
|
||||
another service the load is multiplied by the number of nodes in the system.
|
||||
|
||||
* Any impacts to the deployment performance
|
||||
|
||||
* A small change in a utility function or a commonly used decorator can have a
|
||||
large impacts on performance.
|
||||
|
||||
* Calls which result in a database queries (whether direct or via conductor)
|
||||
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?
|
||||
|
||||
Other 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? Should they be more generic than
|
||||
proposed? 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 those upgrading from the previous release,
|
||||
need to be aware of. Also describe any plans to deprecate configuration
|
||||
values or features. Consider the potential implications of automated
|
||||
deployment technologies.
|
||||
|
||||
Developer impact
|
||||
----------------
|
||||
|
||||
Discuss things that will affect other developers working on StarlingX.
|
||||
|
||||
Upgrade impact
|
||||
--------------
|
||||
|
||||
Describe any potential upgrade impact on the system, such as:
|
||||
|
||||
* StarlingX supports N-1 version for rolling upgrades. Does the proposed change
|
||||
need to consider older code running that may impact how the new change
|
||||
functions, for example, by changing or overwriting global state in the
|
||||
database? This is generally most problematic when making changes that involve
|
||||
multiple compute hosts, like move operations such as migrate, resize,
|
||||
unshelve and evacuate.
|
||||
|
||||
|
||||
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>
|

Repos Impacted
|
||||
--------------
|
||||
|
||||
List repositories in StarlingX that are impacted by this spec.
|
||||
|
||||
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 in StarlingX, 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 StarlingX 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 your plans for testing this feature. Your plans should
|
||||
include:
|
||||
|
||||
* A discussion of whether or not you plan to create unit tests for the
|
||||
feature.
|
||||
|
||||
* A discussion of how the new functionality you are adding
|
||||
will be tested by you. Describe at a high level the test scenarios that
|
||||
are needed and which (if any) can be covered by existing tests. Identify
|
||||
any areas outside of your changes that could be impacted by them, and
|
||||
thus would need to be tested.
|
||||
|
||||
* Once we have an infrastructure for
|
||||
automated functional testing for StarlingX,
|
||||
this section should include a brief description of the kinds of test
|
||||
cases that can be automated within that framework for this feature.
|
||||
|
||||
* any existing tests that should be run to test this feature.
|
||||
|
||||
Your test plan should cover the important scenarios that
|
||||
need to be tested. Please think about
|
||||
edge cases as well. Your test plan should cover all of
|
||||
the StarlingX physical (e.g. simplex, duplex, standard)
|
||||
configurations that might be impacted by the changes you are making.
|
||||
|
||||
Your changes may impact several parts of the operation of a StarlingX
|
||||
deployment. Please work with your sub-project PL, TL and sub-project
|
||||
team to prepare and review your test plan. Successful completion of
|
||||
the feature test plan is a gate to the code being approved
|
||||
by the project's core reviewers.
|
||||
|
||||
Documentation Impact
|
||||
====================
|
||||
|
||||
Which audiences are affected most by this change, and which documentation
|
||||
titles for StarlingX 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. For example, the End User Guide would
|
||||
need to be updated if the change offers a new feature available through the CLI
|
||||
or dashboard. If a config option changes or is deprecated, note here that the
|
||||
documentation needs to be updated to reflect this specification's change.
|
||||
|
||||
References
|
||||
==========
|
||||
|
||||
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:
|
||||
|
||||
* Links to mailing list or IRC discussions
|
||||
|
||||
* Links to notes from a summit session
|
||||
|
||||
* Links to relevant research, if appropriate
|
||||
|
||||
* Related specifications as appropriate (e.g. if it's an EC2 thing, link the
|
||||
EC2 docs)
|
||||
|
||||
* Anything else you feel it is worthwhile to refer to
|
||||
|
||||
|
||||
History
|
||||

|
||||
|
||||
Optional section intended to be used each time the spec is updated to describe
|
||||
new design, API or any database schema updated. Useful to let reader understand
|
||||
