Watcher Project Plans

Priorities

During each design summit, we agree what the whole community wants to focus on for the upcoming release. This is the output of those discussions:

Specifications

Here you can find the specs, and spec template, for each release:

specs/train/index specs/stein/index specs/rocky/index specs/queens/index specs/pike/index specs/ocata/index specs/newton/index specs/mitaka/index

There are also some approved backlog specifications that are looking for owners:

specs/backlog/index

Process

The lifecycle of a specification

Developers proposing a specification should propose a new file in the approved directory. watcher-specs-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. Developers are 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 into Watcher, 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 watcher-specs-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/mitaka/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 projects for people looking to get involved with Watcher. 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 watcher-specs-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 Watcher 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.

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.
• watcher-specs-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 Watcher 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>. watcher-specs-core can approve the specification at any time, but it won't merge until the code we need to land in the other project has merged as well.
