+Specifications for Pacemaker Resource Agents for OpenStack
+==========================================================
+
+
+This git repository is used to hold approved design specifications for
+additions to the Pacemaker Resource Agents for OpenStack project.
+Reviews of the specs are done in gerrit, using a similar workflow to
+how we review and merge changes to the code itself. For specific
+policies around specification review, refer to the end of this
+document.
+
+The layout of this repository is::
+
+  specs/<release>/
+
+Where there are two sub-directories:
+
+  specs/<release>/approved: specifications approved but not yet implemented
+  specs/<release>/implemented: implemented specifications
+
+The lifecycle of a specification
+--------------------------------
+
+Developers proposing a specification should propose a new file in the
+``approved`` directory. ``openstack-resource-agents-core`` will review
+the change in the usual manner for the OpenStack project, and eventually it
+will get merged if a consensus is reached. At this time the Launchpad blueprint
+is also approved.  The developer is then free to propose code reviews to
+implement their specification. These reviews should be sure to reference the
+Launchpad blueprint in their commit message for tracking purposes.
+
+Once all code for the feature is merged, the Launchpad blueprint is
+marked complete. As the developer of an approved specification it is your
+responsibility to mark your blueprint complete when all of the required
+patches have merged.
+
+Periodically, someone from ``openstack-resource-agents-core`` will move
+implemented specifications from the ``approved`` directory to the
+``implemented`` directory. Whilst individual developers are welcome to propose
+this move for their implemented specifications, we have generally just done
+this in a batch at the end of the release cycle. It is important to create
+redirects when this is done so that existing links to the approved
+specification are not broken. Redirects aren't symbolic links, they are defined
+in a file which sphinx consumes. An example is at ``specs/newton/redirects``.
+
+This directory structure allows you to see what we thought about doing,
+decided to do, and actually got done. Users interested in functionality in a
+given release should only refer to the ``implemented`` directory.
+
+Example specifications
+----------------------
+
+You can find an example spec in ``specs/template.rst``.
+
+Backlog specifications
+----------------------
+
+Additionally, we allow the proposal of specifications that do not have a
+developer assigned to them. These are proposed for review in the same manner as
+above, but are added to::
+
+  specs/backlog/approved
+
+Specifications in this directory indicate the original author has either
+become unavailable, or has indicated that they are not going to implement the
+specification. The specifications found here are available as opportunities for
+people looking to get involved with the project. If you are interested in
+claiming a spec, start by posting a review for the specification that moves it
+from this directory to the next active release. Please set yourself as the new
+`primary assignee` and maintain the original author in the `other contributors`
+list.
+
+Working with gerrit and specification unit tests
+------------------------------------------------
+
+For more information about working with gerrit, see
+http://docs.openstack.org/infra/manual/developers.html#development-workflow
+
+To validate that the specification is syntactically correct (i.e. get more
+confidence in the Jenkins result), please execute the following command::
+
+  $ tox
+
+After running ``tox``, the documentation will be available for viewing in HTML
+format in the ``doc/build/`` directory.
+
+Specification review policies
+=============================
+
+There are a number of review policies which ``openstack-resource-agents-core``
+will apply when reviewing proposed specifications. They are:
+
+Trivial specifications
+----------------------
+
+Proposed changes which are trivial (very small amounts of code) and don't
+change any of our public APIs are sometimes not required to provide a
+specification. In these cases a Launchpad blueprint is considered sufficient.
+These proposals are approved during the open discussion portion of the `weekly
+HA IRC meeting`_. If you think your proposed feature is trivial and meets these
+requirements, we recommend you bring it up for discussion there before writing
+a full specification.
+
+.. _weekly HA IRC meeting: https://wiki.openstack.org/wiki/Meetings/HATeamMeeting
+
+Previously approved specifications
+----------------------------------
+
+`Specifications are only approved for a single release`. If your specification
+was previously approved but not implemented (or not completely implemented),
+then you must seek re-approval for the specification. You can re-propose your
+specification by doing the following:
+
+* Copy (not move) your specification to the right directory for the current release.
+* Update the document to comply with the new template.
+* If there are no functional changes to the specification (only template changes) then add the `Previously-approved: <release>` tag to your commit message.
+* Send for review.
+* ``openstack-resource-agents-core`` will merge specifications which meet
+  these requirements with a single +2.
+
+Specifications which depend on merging code in other OpenStack projects
+-----------------------------------------------------------------------
+
+For specifications `that depend on code in other OpenStack projects merging` we
+will not approve the openstack-resource-agents specification until the code in
+that other project has merged. To indicate your specification is in this state,
+please use the Depends-On git commit message tag. The correct format is
+`Depends-On: <change id of other work>`. ``openstack-resource-agents-core`` can
+approve the specification at any time, but it wont merge until the code we need
+to land in the other project has merged as well.

+The spec backlog is a place for the team to record decisions about

+A spec that exists here is something that either needs a driver or

+Highly Available VMs
+--------------------
+
+The OpenStack `Product Working Group`_ is maintaining a user story for
+`High Availability for Virtual Machines`_.  During and since the
+Austin summit, there has been a lot of discussion within the OpenStack
+HA community about how to converge on an upstream implementation which
+fulfils this user story, which has been captured in the
+`newton-instance-ha etherpad`_ and in the minutes of the `weekly HA
+IRC meetings`_.  The first step is to write a series of specs which
+will describe the architectural design and corresponding deliverables
+for each of the components which were agreed as necessary for a
+flexible, modular solution.

+==========================================
+Example Spec - The title of your blueprint
+==========================================
+
+Include the URL of your launchpad blueprint:
+
+https://blueprints.launchpad.net/openstack-resource-agents/+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 the openstack-resource-agents-spec and blueprint process:
+
+* Not all blueprints need a spec. For more information see
+  http://docs.openstack.org/developer/openstack-resource-agents/blueprints.html
+
+* 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.
+  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 match the launchpad URL, for
+  example a URL of: https://blueprints.launchpad.net/openstack-resource-agents/+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.
+
+* If your specification proposes any changes to an API such as changing
+  parameters which can be returned or accepted, or even the semantics of what
+  happens when a client calls into the API, then you should add the APIImpact
+  flag to the commit message. Specifications with the APIImpact flag can be
+  found with the following query:
+
+  https://review.openstack.org/#/q/status:open+project:openstack/openstack-resource-agents-specs+message:apiimpact,n,z
+
+
+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 if the problem and
+proposed change fit in ``openstack-resource-agents``, 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 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
+---------------
+
+Each API method which is either added or changed 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 definition do not need to be included.
+
+  * URL for the resource
+
+    * URL should not include underscores, and use hyphens instead.
+
+  * Parameters which can be passed via the url
+
+  * JSON schema definition for the request body data if allowed
+
+    * Field names should use snake_case style, not CamelCase or MixedCase
+      style.
+
+  * JSON schema definition for the response body data if any
+
+    * Field names should use snake_case style, not CamelCase or MixedCase
+      style.
+
+* 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?
+
+* What does the operator interface 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.
+
+* Scheduler filters get called once per host for every instance being created,
+  so any latency they introduce is linear with the size of 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 driver API, discussion of how
+  other hypervisors 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.
+
+
+Dependencies
+============
+
+* Include specific references to specs and/or blueprints, that this
+  one either depends on or is related to.
+
+* If this introduces 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 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, or can be simulated inside the tree.
+
+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
+====================
+
+Which audiences are affected most by this change, and which documentation
+titles on docs.openstack.org 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 Operations Guide targets
+cloud operators, and 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 what's happened along the time.
