Example Spec - The title of your blueprint
==========================================
Include the URL of your launchpad blueprint:
https://blueprints.launchpad.net/tacker/+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 80 columns.
* The filename in the git repository should match the launchpad URL, for
example a URL of: https://blueprints.launchpad.net/tacker/+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, text representations
are preferred. http://asciiflow.com/ is a very nice tool to assist with
making ascii diagrams. blockdiag is another tool. These are described below.
If you require an image (screenshot) for your BP, attaching that to the BP
and checking it in is also accepted. However, text representations are prefered.

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.
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 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, for example if you
need to take into account existing instances, or modify other existing data
describe how that will work.
REST API impact
---------------
For each API resource to be implemented using Tacker's attribute map
facility (see the tacker.api.v2.attributes), describe the resource
collection and specify the name, type, and other essential details of
each new or modified attribute. A table similar to the following may
be used:
+----------+-------+---------+---------+------------+--------------+
|Attribute |Type |Access |Default |Validation/ |Description |
|Name | | |Value |Conversion | |
+==========+=======+=========+=========+============+==============+
|id |string |RO, all |generated|N/A |identity |
| |(UUID) | | | | |
+----------+-------+---------+---------+------------+--------------+
|name |string |RW, all |'' |string |human-readable|
| | | | | |name |
+----------+-------+---------+---------+------------+--------------+
|color |string |RW, admin|'red' |'red', |color |
| | | | |'yellow', or|indicating |
| | | | |'green' |state |
+----------+-------+---------+---------+------------+--------------+
Here is the other example of the table using csv-table
.. csv-table:: CSVTable
:header: Attribute Name,Type,Access,Default Value,Validation Conversion,Description
id,string (UUID),"RO, all",generated,N/A,identity
name,string,"RW, all","''",string,human-readable name
color,string,"RW, admin",red,"'red', 'yellow' or 'green'",color indicating state
Each API method which is either added or changed that does not use
Tacker's attribute map facility should have the following:
* Specification for the method
* A description of what the method does suitable for use in
user documentation
* Method type (POST/PUT/GET/DELETE)
* Normal http response code(s)
* Expected error http response code(s)
* A description for each possible error code should be included
describing semantic errors which can cause it such as
inconsistent parameters supplied to the method, or when an
instance is not in an appropriate state for the request to
succeed. Errors caused by syntactic problems covered by the JSON
schema defintion do not need to be included.
* URL for the resource
* Parameters which can be passed via the url
* JSON schema definition for the body data if allowed
* JSON schema definition for the response data if any
* Example use case including typical API samples for both data supplied
by the caller and the response
* Discuss any API policy changes, and discuss what things a deployer needs to
think about when defining their API policy. This is in reference to the
policy.json file.
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.
Notifications impact
--------------------
Please specify any changes to notifications. Be that an extra notification,
changes to an existing notification, or removing a notification.
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-tackerclient? 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.
* 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 (for example a flag that other hypervisor drivers might want to
implement as well)? 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. For example, if we
change the directory name that instances are stored in, how do we handle
instance directories created before the change landed? Do we move them? Do
we have a special case in the code? Do we assume that the operator will
recreate all the instances in their cloud?
Developer impact
----------------
Discuss things that will affect other developers working on OpenStack,
such as:
* If the blueprint proposes a change to the API, discussion of how other
plugins 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>
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.
Apart from the main functionality, the developer needs to deliver the following
work items as part of any major blueprint:
* Unit Tests
* Functional Tests
* Feature documentation in doc/source/devref/feature
NOTE: This feature documentation should be treated like code. Preferably
this should be included in the primary patchset itself and not as an
afterthought. This is also mandatory for a blueprint to be marked complete.
Dependencies
============
* Include specific references to specs and/or blueprints in tacker, 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 Tacker (such as the glance v2 API when we previously only required v1),
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.
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. link any vendor documentation)
* Anything else you feel it is worthwhile to refer to

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.
Notifications impact
--------------------
Please specify any changes to notifications. Be that an extra notification,
changes to an existing notification, or removing a notification.
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-tackerclient? 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.
* 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 (for example a flag that other hypervisor drivers might want to
implement as well)? 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. For example, if we
change the directory name that instances are stored in, how do we handle
instance directories created before the change landed? Do we move them? Do
we have a special case in the code? Do we assume that the operator will
recreate all the instances in their cloud?
Developer impact
----------------
Discuss things that will affect other developers working on OpenStack,
such as:
* If the blueprint proposes a change to the API, discussion of how other
plugins 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>
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.
Apart from the main functionality, the developer needs to deliver the following
work items as part of any major blueprint:
* Unit Tests
* Functional Tests
* Feature documentation in doc/source/devref/feature
NOTE: This feature documentation should be treated like code. Preferably
this should be included in the primary patchset itself and not as an
afterthought. This is also mandatory for a blueprint to be marked complete.
Dependencies
============
* Include specific references to specs and/or blueprints in tacker, 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 Tacker (such as the glance v2 API when we previously only required v1),
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.
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. link any vendor documentation)
* Anything else you feel it is worthwhile to refer to

Example Spec - The title of your blueprint
==========================================
Include the URL of your launchpad blueprint:
https://blueprints.launchpad.net/tacker/+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 80 columns.
* The filename in the git repository should match the launchpad URL, for
example a URL of: https://blueprints.launchpad.net/tacker/+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, text representations
are preferred. http://asciiflow.com/ is a very nice tool to assist with
making ascii diagrams. blockdiag is another tool. These are described below.
If you require an image (screenshot) for your BP, attaching that to the BP
and checking it in is also accepted. However, text representations are prefered.

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.
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 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, for example if you
need to take into account existing instances, or modify other existing data
describe how that will work.
REST API impact
---------------
For each API resource to be implemented using Tacker's attribute map
facility (see the tacker.api.v2.attributes), describe the resource
collection and specify the name, type, and other essential details of
each new or modified attribute. A table similar to the following may
be used:
+----------+-------+---------+---------+------------+--------------+
|Attribute |Type |Access |Default |Validation/ |Description |
|Name | | |Value |Conversion | |
+==========+=======+=========+=========+============+==============+
|id |string |RO, all |generated|N/A |identity |
| |(UUID) | | | | |
+----------+-------+---------+---------+------------+--------------+
|name |string |RW, all |'' |string |human-readable|
| | | | | |name |
+----------+-------+---------+---------+------------+--------------+
|color |string |RW, admin|'red' |'red', |color |
| | | | |'yellow', or|indicating |
| | | | |'green' |state |
+----------+-------+---------+---------+------------+--------------+
Here is the other example of the table using csv-table
.. csv-table:: CSVTable
:header: Attribute Name,Type,Access,Default Value,Validation Conversion,Description
id,string (UUID),"RO, all",generated,N/A,identity
name,string,"RW, all","''",string,human-readable name
color,string,"RW, admin",red,"'red', 'yellow' or 'green'",color indicating state
Each API method which is either added or changed that does not use
Tacker's attribute map facility should have the following:
* Specification for the method
* A description of what the method does suitable for use in
user documentation
* Method type (POST/PUT/GET/DELETE)
* Normal http response code(s)
* Expected error http response code(s)
* A description for each possible error code should be included
describing semantic errors which can cause it such as
inconsistent parameters supplied to the method, or when an
instance is not in an appropriate state for the request to
succeed. Errors caused by syntactic problems covered by the JSON
schema defintion do not need to be included.
* URL for the resource
* Parameters which can be passed via the url
* JSON schema definition for the body data if allowed
* JSON schema definition for the response data if any
* Example use case including typical API samples for both data supplied
by the caller and the response
* Discuss any API policy changes, and discuss what things a deployer needs to
think about when defining their API policy. This is in reference to the
policy.json file.
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.
