| <p>rustc is maintained by the <a href="https://www.rust-lang.org/governance/teams/compiler">Rust compiler team</a>. The people who belong to |
| this team collectively work to track regressions and implement new features. |
| Members of the Rust compiler team are people who have made significant |
| contributions to rustc and its design.</p> |
| <h2 id="discussion"><a class="header" href="#discussion">Discussion</a></h2> |
| <p>Currently the compiler team chats in Zulip:</p> |
| <ul> |
| <li>Team chat occurs in the <a href="https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler"><code>t-compiler</code></a> stream on the Zulip instance</li> |
| <li>There are also a number of other associated Zulip streams, |
| such as <a href="https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp"><code>t-compiler/help</code></a>, where people can ask for help |
| with rustc development, or <a href="https://rust-lang.zulipchat.com/#narrow/stream/238009-t-compiler.2Fmeetings"><code>t-compiler/meetings</code></a>, |
| where the team holds their weekly triage and steering meetings.</li> |
| </ul> |
| <h2 id="reviewers"><a class="header" href="#reviewers">Reviewers</a></h2> |
| <p>If you're interested in figuring out who can answer questions about a |
| particular part of the compiler, or you'd just like to know who works on what, |
| check out <a href="https://github.com/rust-lang/rust/blob/master/triagebot.toml">triagebot.toml's assign section</a>. |
| It contains a listing of the various parts of the compiler and a list of people |
| who are reviewers of each part.</p> |
| <h2 id="rust-compiler-meeting"><a class="header" href="#rust-compiler-meeting">Rust compiler meeting</a></h2> |
| <p>The compiler team has a weekly meeting where we do triage and try to |
| generally stay on top of new bugs, regressions, and discuss important |
| things in general. |
| They are held on <a href="https://rust-lang.zulipchat.com/#narrow/stream/238009-t-compiler.2Fmeetings">Zulip</a>. It works roughly as follows:</p> |
| <ul> |
| <li><strong>Announcements, MCPs/FCPs, and WG-check-ins:</strong> We share some |
| announcements with the rest of the team about important things we want |
| everyone to be aware of. We also share the status of MCPs and FCPs and we |
| use the opportunity to have a couple of WGs giving us an update about |
| their work.</li> |
| <li><strong>Check for beta and stable nominations:</strong> These are nominations of things to |
| backport to beta and stable respectively. |
| We then look for new cases where the compiler broke previously working |
| code in the wild. Regressions are important issues to fix, so it's |
| likely that they are tagged as P-critical or P-high; the major |
| exception would be bug fixes (though even there we often <a href="./bug-fix-procedure.html">aim to give |
| warnings first</a>).</li> |
| <li><strong>Review P-critical and P-high bugs:</strong> P-critical and P-high bugs are |
| those that are sufficiently important for us to actively track |
| progress. P-critical and P-high bugs should ideally always have an |
| assignee.</li> |
| <li><strong>Check S-waiting-on-team and I-nominated issues:</strong> These are issues where feedback from |
| the team is desired.</li> |
| <li><strong>Look over the performance triage report:</strong> We check for PRs that made the |
| performance worse and try to decide if it's worth reverting the performance regression or if |
| the regression can be addressed in a future PR.</li> |
| </ul> |
| <p>The meeting currently takes place on Thursdays at 10am Boston time |
| (UTC-4 typically, but daylight savings time sometimes makes things |
| complicated).</p> |
| <h2 id="team-membership"><a class="header" href="#team-membership">Team membership</a></h2> |
| <p>Membership in the Rust team is typically offered when someone has been |
| making significant contributions to the compiler for some |
| time. Membership is both a recognition but also an obligation: |
| compiler team members are generally expected to help with upkeep as |
| well as doing reviews and other work.</p> |
| <p>If you are interested in becoming a compiler team member, the first |
| thing to do is to start fixing some bugs, or get involved in a working |
| group. One good way to find bugs is to look for |
| <a href="https://github.com/rust-lang/rust/issues?q=is%3Aopen+is%3Aissue+label%3AE-easy">open issues tagged with E-easy</a> |
| or |
| <a href="https://github.com/rust-lang/rust/issues?q=is%3Aopen+is%3Aissue+label%3AE-mentor">E-mentor</a>.</p> |
| <p>You can also dig through the graveyard of PRs that were |
| <a href="https://github.com/rust-lang/rust/pulls?q=is%3Apr+label%3AS-inactive">closed due to inactivity</a>, |
| some of them may contain work that is still useful - refer to the |
| associated issues, if any - and only needs some finishing touches |
| for which the original author didn't have time.</p> |
| <h3 id="r-rights"><a class="header" href="#r-rights">r+ rights</a></h3> |
| <p>Once you have made a number of individual PRs to rustc, we will often |
| offer r+ privileges. This means that you have the right to instruct |
| "bors" (the robot that manages which PRs get landed into rustc) to |
| merge a PR |
| (<a href="https://bors.rust-lang.org/">here are some instructions for how to talk to bors</a>).</p> |
| <p>The guidelines for reviewers are as follows:</p> |
| <ul> |
| <li>You are always welcome to review any PR, regardless of who it is |
| assigned to. However, do not r+ PRs unless: |
| <ul> |
| <li>You are confident in that part of the code.</li> |
| <li>You are confident that nobody else wants to review it first. |
| <ul> |
| <li>For example, sometimes people will express a desire to review a |
| PR before it lands, perhaps because it touches a particularly |
| sensitive part of the code.</li> |
| </ul> |
| </li> |
| </ul> |
| </li> |
| <li>Always be polite when reviewing: you are a representative of the |
| Rust project, so it is expected that you will go above and beyond |
| when it comes to the <a href="https://www.rust-lang.org/policies/code-of-conduct">Code of Conduct</a>.</li> |
| </ul> |
| <h3 id="reviewer-rotation"><a class="header" href="#reviewer-rotation">Reviewer rotation</a></h3> |
| <p>Once you have r+ rights, you can also be added to the <a href="https://github.com/rust-lang/rust/blob/36285c5de8915ecc00d91ae0baa79a87ed5858d5/triagebot.toml#L528-L577">reviewer rotation</a>. |
| <a href="https://github.com/rust-lang/triagebot/">triagebot</a> is the bot that <a href="https://forge.rust-lang.org/triagebot/pr-assignment.html">automatically assigns</a> incoming PRs to reviewers. |
| If you are added, you will be randomly selected to review |
| PRs. If you find you are assigned a PR that you don't feel comfortable |
| reviewing, you can also leave a comment like <code>r? @so-and-so</code> to assign |
| to someone else — if you don't know who to request, just write <code>r? @nikomatsakis for reassignment</code> and @nikomatsakis will pick someone |
| for you.</p> |
| <p>Getting on the reviewer rotation is much appreciated as it lowers the |
| review burden for all of us! However, if you don't have time to give |
| people timely feedback on their PRs, it may be better that you don't |
| get on the list.</p> |
| <h3 id="full-team-membership"><a class="header" href="#full-team-membership">Full team membership</a></h3> |
| <p>Full team membership is typically extended once someone made many |
| contributions to the Rust compiler over time, ideally (but not |
| necessarily) to multiple areas. Sometimes this might be implementing a |
| new feature, but it is also important — perhaps more important! — to |
| have time and willingness to help out with general upkeep such as |
| bugfixes, tracking regressions, and other less glamorous work.</p> |
