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 the process: - -* 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. - -* This is not intended to be extensive documentation for a new feature. - -* 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. - -* 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 sphinx - -* 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? - -At this point, if you would like to just get feedback on the problem and -proposed change, 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. - -OVSDB schema 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? - -User interface impact ---------------------- - -Each user interface that is either added, changed or removed should have the -following: - -* Specification for the user interface - -* Example use case including typical examples for both data supplied - by the caller and the response - -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 interface in a way that may impact security, such as - a new way to access sensitive information? - -* 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 interaction to consume significant server resources? - -Other end user impact ---------------------- - -Aside from the user interfaces, are there other ways a user will interact with this -feature? - -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: - -* 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 Open vSwitch -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 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 Open vSwitch, -such as: - -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: - <email address> - -Other contributors: - <email address> - -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 -============ - -* If this requires functionality of another project that is not currently used - document that fact. - -* Does this feature require any new library dependencies or code otherwise not - included in Open vSwitch? 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. - -Please discuss how the change will be tested: Open vSwitch unit tests, VSPERF -performance tests, Yardstick tests, etc. - -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 -==================== - -Which audiences are affected most by this change, and which documentation -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. 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 relevant research, if appropriate - -* Related specifications as appropriate - -* 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 what's happened along the -time. - -.. list-table:: Revisions - :header-rows: 1 - - * - Release Name - - Description - * - 2.x - - Introduced |
