Nix maintainers team

Motivation

The goal of the team is to help other people to contribute to Nix.

Meeting protocol

The team meets twice a week:

  • Discussion meeting: Fridays 13:00-14:00 CET

    1. Triage issues and pull requests from the No Status column (30 min)
    2. Discuss issues and pull requests from the To discuss column (30 min)
  • Work meeting: Mondays 13:00-15:00 CET

    1. Code review on pull requests from In review.
    2. Other chores and tasks.

Meeting notes are collected on a collaborative scratchpad, and published on Discourse under the Nix category.

Project board protocol

The team uses a GitHub project board for tracking its work.

Issues on the board progress through the following states:

  • No Status

    During the discussion meeting, the team triages new items. To be considered, issues and pull requests must have a high-level description to provide the whole team with the necessary context at a glance.

    On every meeting, at least one item from each of the following categories is inspected:

    1. critical
    2. security
    3. regression
    4. bug

    Team members can also add pull requests or issues they would like the whole team to consider.

    If there is disagreement on the general idea behind an issue or pull request, it is moved to To discuss, otherwise to In review.

  • To discuss

    Pull requests and issues that are deemed important and controversial are discussed by the team during discussion meetings.

    This may be where the merit of the change itself or the implementation strategy is contested by a team member.

    As a general guideline, the order of items is determined as follows:

    • Prioritise pull requests over issues

      Contributors who took the time to implement concrete change proposals should not wait indefinitely.

    • Prioritise fixing bugs over documentation, improvements or new features

      The team values stability and accessibility higher than raw functionality.

    • Interleave issues and PRs

      This way issues without attempts at a solution get a chance to get addressed.

  • In review

    Pull requests in this column are reviewed together during work meetings. This is both for spreading implementation knowledge and for establishing common values in code reviews.

    When the overall direction is agreed upon, even when further changes are required, the pull request is assigned to one team member.

  • Assigned for merging

    One team member is assigned to each of these pull requests. They will communicate with the authors, and make the final approval once all remaining issues are addressed.

    If more substantive issues arise, the assignee can move the pull request back to To discuss to involve the team again.

The process is illustrated in the following diagram:
