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 +--------------- + +Octavia includes several internal APIs (all of which should be versioned). +In defining how API(s) are affected by this change, make sure to +clearly indicate which API(s) specifically are being altered, which version +of the API(s) are being altered, and other pertinent details as described +below. + +While we are not using Neutron's attribute map facility since Octavia is +not Neutron, following the tried-and-true guidelines Neutron uses around +API changes is a good idea, including defining attribute map tables. For +reference: + +For each API resource to be implemented using Neutron's attribute map +facility (see the neutron.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 +Neutron'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? +Keep in mind that 'user' in this context could mean either tenant or operator. + +* Does this change have an impact on python-neutronclient? 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: + + +Other contributors: + + +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 octavia, 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 Octavia 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.
