Galaxy Issue Management¶

The purpose of this document is to formalize how we manage the full cycle (reporting, tracking progress, resolution) of both feature/enhancement ideas and bugs, as well as providing a few general guidelines for longer term planning for various Galaxy related projects. Some inspiration taken from the way the Docker project labels issues.

Issue Reporting¶

Issues (bugs, feature requests, etc.) should be reported at GitHub issues, and handling of issues follows the procedures described in the issues document.

Milestones¶

Every pull request should, prior to merge, be assigned to the milestone corresponding to the Galaxy release it will first appear in (15.10, 16.01, and so on). This, along with the tags applied, will be used to generate the release notes.

Any non-PR issue assigned to a milestone must be resolved or reassigned prior to publishing that release. This is the primary mechanism by which we force reconciliation (issue/bug fixed, closed, or intentionally postponed) prior to release, and prevent things falling through the cracks. In practice, bugs should almost always be tagged with a milestone which forces the reconciliation date. Issues may be, but they don’t necessarily have to be – this is subjective and it depends on whether or not the issue should be revisited prior to the corresponding release.

Effective use of milestones should prevent bugs from falling through the cracks, and will provide a mechanism for forcing the revisitation(and thus progress or even potential discard) of ideas for enhancements or features.

Deferring Issues¶

To prevent the review of issues attached to milestones from becoming too cumbersome, and to encourage active review and handling of issues, any contributor can choose to ‘defer’ an issue attached to an upcoming release milestone to a later one. To do this, simply reassign the issue to the new milestone and leave a comment so that others notice, something like ‘Issue deferred to target_milestone_reference, does not block release current_milestone_reference’.

Once deferred, an issue can’t simply be reattached back to the earlier milestone – this requires a PR. The intent here is to make it such that if a contributor wants to force an issue to be handle with a release, they need to put the work forward to do so or convince someone else to.

Labeling Structure¶

To allow for easy search, filtering, and general issue management every issue or PR (not tagged procedures or planning) is required to have three labels which indicate the type, status, and focus area of the issue. Any issue without these three tags will be automatically have a triage label applied indicating that it needs human intervention to be correctly tagged. These triage tagged issues will be regularly reviewed and tagged as appropriate.

Kind Labels¶

The ‘kind’ label set is used for classifying the type of contribution or request/report to separate enhancements and new features from bugs, etc.

kind/bug - something is broken, and it needs fixing
kind/enhancement - polish to an existing feature or interface
kind/feature - something brand new
kind/refactoring - refactoring of existing code, no functional changes

Status Labels¶

The status of an issue or PR should be tracked using the following labels:

status/planning - the issue planning phase, this issue may potentially need more information (or just more thinking) to proceed to a work in progress
status/WIP - this issue or PR is currently being worked on and in the case of a PR, it should not be merged until this tag is removed
status/review - PR is complete and ready for review, or when applied to an issue it is thought to be resolved but needs verification

We use the same set of status tags for PRs and issues to keep things simple, but not every PR or issue needs to go through every state. For example, it’ll be common for a PR to be submitted with the label ‘status/review’, and get merged without needing to go through the rest of the states.

Note that there are no status/complete, status/wontfix, status/duplicate, or other terminal status indicators. This is intentional to keep the tail end of bookkeeping from getting onerous. These sorts of terminal states and their justifications (e.g. the reason why it’s a wontfix, or a reference to the duplicate issue) should be indicated in the closing comment by the issue closer.

Area Labels¶

The ‘area’ label is used for tagging issues and pull requests to a particular focus area. This allows for easy searching within that particular domain, as well as more organized release notes.

area/admin - Changes to admin functionality of the Galaxy webapp.
area/API
area/cleanup - General code cleanup.
area/cwl - changes related to supporting the common workflow language in Galaxy
area/database - Change requires a modification to Galaxy’s database.
area/dataset-collections
area/datatypes - Changes to Galaxy’s datatypes
area/datatype-framework - Changes to Galaxy’s datatype and metadata framework
area/dependencies - Changes related to Python or JavaScript dependencies of Galaxy itself
area/documentation
area/framework
area/GIEs
area/histories
area/i18n
area/libraries - Change related to data libraries.
area/jobs
area/objectstore
area/performance
area/reports
area/security
area/system - Changes to scripts used to run or manage Galaxy.
area/testing
area/testing/api
area/testing/integration
area/testing/selenium
area/tool-framework
area/tool-dependencies - Changes to dependency resolution (including Conda).
area/tools - Changes to specific tools in Galaxy.
area/toolshed- Changes to the tool shed client or server.
area/UI-UX
area/upload
area/util
area/visualizations
area/webhooks
area/workflows
area/workflows/subworkflows

New labels should be proposed by opening a pull request against this document in the dev branch of Galaxy.

Other Useful Labels¶

While the three labels sets indicating kind, status, and area are required there are several other labels that are be useful and/or have special purpose.

procedures is a special tag that indicates that the issue is related to project governance, and it overrides the need for the trio of kind/status/area tags, and these are never auto-flagged for triage. More details are available in the ORGANIZATION document.
planning is also a special tag that indicates the issue is related to larger-scale issue planning. These issues are typically meta-issues containing checklists and references to other issues which are subcomponents and stepping stones necessary for issue resolution. These can utilize the area/* tags but are not required to. Status and type make little sense here.
roadmap is a reserved tag for the primary project roadmap. This is a meta-issue that is not expected to be completed, but rather serves as an entry point to the high level development of the project.
friendliness/beginner can be used to indicate a nice entry-level issue that only requires limited understanding of the larger Galaxy framework and ecosystem. This is useful for encouraging new contributors.
friendliness/intermediate can be used to indicate an advanced level issue that requires decent understanding of the larger Galaxy framework and system.
friendliness/unfriendly can be used to mark issues that require deep understanding of the framework and/or exquisite programming abilities.
minor is a special tag used to generate release notes. It should only be applied to pull requests made by committers that fix functionality modified during the same release cycle. Such fixes are unimportant for release notes. No pull request issued by someone outside the committers group should have this tag applied because these pull requests must be highlighted in the release notes.
major is a special tag used to generate release notes. In practice this should be applied to at most a couple dozen pull requests each release and is used to prioritize important items of note for the top of release notes sections.
merge tag used to indicate PR that only merges a change that has been previously added. Used to filter things out of release notes.
feature-request is used to indicate a request for change or feature.
triage is a tag automatically added by a GalaxyBot to indicate that the issue needs to be evaluated and properly tagged.
hacktoberfest is a tag that encourages contributions to Galaxy codebase by including these issues in the Hacktoberfest event. Similar to friendliness/beginner tag in other characteristics.

The Roadmap¶

We will maintain a single roadmap tagged meta-issue which will describe (at a very high level) the current major areas of focus for the project. This is similar to our PRIORITIES 2014/15 cards on Trello. Using Task Lists, this issue will link to sub-issues which will go into much more detail, might have its own checklists to even more subcomponent cards, and so on.

This roadmap issue will be assigned to every release milestone, forcing periodic review of the roadmap.

Voting¶

Users can vote for issues by commenting with a +1. It’s possible to sort the issue list by ‘most commented’ which would be a good indicator of what issues are ‘hot’, though this doesn’t necessarily indicate a high vote. It’s possible that that this is good enough and in some ways potentially more useful to find ‘hot’ issues than a flat vote count.

Automation¶

For now, we will rely on a few simple automation rules:

All issues, unless tagged procedures or planning will automatically be tagged triage, indicating that they require attention.
All PRs that are not assigned to a milestone will be tagged triage to indicate that they require attention prior to merge.
