Committers are individuals with repository write access. While everyone can and is encouraged to contribute by reviewing code, committers are responsible for final approval and merge. Committers must ensure that any code merged meets a high quality bar, has been properly discussed, and the design rationale adequately explained and documented. Making a judgement on when these requirements have been met is fundamental to the role.

When reviewing a pull request, committers have a range of options. They are entrusted to use their judgement along with any guidelines or recommendations set by the Technical Committee (TC). Options include:

  • Straight-forward approval. The contribution doesn't require an RFC or further review by others. Committers should only use this for cases where they have sufficient expertise and are confident no additional review is needed.
  • Approval, but please get an additional LGTM from other named reviewers.
  • Request for changes.
  • Request for further design rationale be written up and shared (but a full RFC isn't necessary).
  • Request that an RFC be written up and submitted.

Where Committers disagree on the path forwards for a given PR and are unable to reach an agreement, the review moves to the TC.

Committers are proposed by and voted on by the TC. Committers should:

  • Be active contributors to the project, with a history of high quality contributions, including code reviews.
  • Be familiar with the project processes and rules, and be able to apply them fairly.
  • Be responsive to feedback from TC members on their review approach and interpretation of project policy.
  • Work to ensure that stakeholders are properly consulted on any code or design changes.

If you meet the above criteria and are interested in becoming a committer, then approach a TC member to see if they would be willing to propose you. TC members may also reach out to you to ask if you would be interested in becoming a committer.

Under certain exceptional circumstances, the Steering Committee may vote to revoke a committer's status. This may happen in cases such as a committer failing to act as a good citizen within the project and the issue cannot be resolved through discussion. It may also be a natural function of “pruning the tree” as an individual's involvement in the project changes over time.

The list of committers is maintained within the project's Git repository and is available in the COMMITTERS file in the repository root.
