Workflow
Experiments are a way for us to test out new features in Task before committing to them in a major release. Because this concept is built around the idea of feedback from our community, we have built a workflow for the process of introducing these changes. This ensures that experiments are given the attention and time that they need and that we are getting the best possible results out of them.
The sections below describe the various stages that an experiment must go through from its proposal all the way to being released in a major version of Task.
1. Proposal
All experimental features start with a proposal in the form of a GitHub issue.
If the maintainers decide that an issue has enough support and is a breaking
change or is complex/controversial enough to require user feedback, then the
issue will be marked with the label. At this point, the issue
becomes a proposal and a period of consultation begins. During this period, we
request that users provide feedback on the proposal and how it might effect
their use of Task. It is up to the discretion of the maintainers to decide how
long this period lasts.
2. Draft
Once a proposal's consultation ends, a contributor may pick up the work and
begin the initial implementation. Once a PR is opened, the maintainers will
ensure that it meets the requirements for an experimental feature (i.e. flags
are in the right format etc) and merge the feature. Once this code is released,
the status will be updated via the label. This indicates that an
implementation is now available for use in a release and the experiment is open
for feedback.
During the draft period, major changes to the implementation may be made based on the feedback received from users. There are no stability guarantees and experimental features may be abandoned at any time.
3. Candidate
Once an acceptable level of consensus has been reached by the community and
feedback/changes are less frequent/significant, the status may be updated via
the label. This indicates that a proposal is likely to accepted
and will enter a period for final comments and minor changes.
4. Stable
Once a suitable amount of time has passed with no changes or feedback, an
experiment will be given the label. At this point, the functionality
will be treated like any other feature in Task and any changes must be
backward compatible. This allows users to migrate to the new functionality
without having to worry about anything breaking in future releases. This
provides the best experience for users migrating to a new major version.
5. Released
When making a new major release of Task, all experiments marked as
will move to
and their behaviors will become the new default in
Task. Experiments in an earlier stage (i.e. not stable) cannot be released and
so will continue to be experiments in the new version.
Abandoned / Superseded
If an experiment is unsuccessful at any point then it will be given the
or
labels depending on which is more suitable. These
experiments will be removed from Task.
