Contributions Daily Meeting

  • 3 Maintainers should attend to a Contributions Daily Meeting where we sort and label new issues (is:issue label:status/0-needs-triage), and review every Pull Requests
  • Every pull request should be checked during the Contributions Daily Meeting
    • Even if it’s already assigned
    • Even PR labelled with contributor/waiting-for-corrections or contributor/waiting-for-feedback
  • Issues labeled with priority/P0 and priority/P1 should be assigned.
  • Modifying an issue or a pull request (labels, assignees, milestone) is only possible:
    • During the Contributions Daily Meeting
    • By an assigned maintainer
    • In case of emergency, if a change proposal is approved by 2 other maintainers (on Slack, Discord, Discourse, etc)

PR review process:

  • The status needs-design-review is only used in complex/heavy/tricky PRs.
  • From 1 to 2: 1 comment that says “design LGTM” (by a senior maintainer).
  • From 2 to 3: 3 LGTM approvals by any maintainer.
  • If needed, a specific maintainer familiar with a particular domain can be requested for the review.
  • If a PR has been implemented in pair programming, one peer's LGTM goes into the review for free
  • Amending someone else's pull request is authorized only in emergency, if a rebase is needed, or if the initial contributor is silent

We use PRM to manage locally pull requests.

Update and Merge Pull Request.

The maintainer giving the final LGTM must add the status/3-needs-merge label to trigger the merge bot.

By default, a squash-rebase merge will be carried out. To preserve commits, add bot/merge-method-rebase before status/3-needs-merge.

The status status/4-merge-in-progress is only used by the bot.

If the bot is not able to perform the merge, the label bot/need-human-merge is added.
In such a situation, solve the conflicts/CI/... and then remove the label bot/need-human-merge.

To prevent the bot from automatically merging a PR, add the label bot/no-merge.

The label bot/light-review decreases the number of required LGTM from 3 to 1.

This label is used when:

  • Updating the vendors from previously reviewed PRs
  • Merging branches into the master
  • Preparing the release
