That last part is subject to being adjusted, allowing individuals to commit directly on non-controversial changes on parts they’re familiar with. +@subsection Addressing Issues + +Peer review (@pxref{Submitting Patches}) and tools such as +@command{guix lint} (@pxref{Invoking guix lint}) and the test suite +(@pxref{Running the Test Suite}) should catch issues before they are +pushed. Yet, commits that ``break'' functionality might occasionally +go through.

The responsibility for both these +things primarily lies with those involved, but like everything this is +a group effort. + +Some issues can directly affect all users---for instance because they +make @command{guix pull} fail or break core functionality, because they +break major packages (at build time or run time), or because they +introduce known security vulnerabilities. + +@cindex reverting commits +The people involved in authoring, reviewing, and pushing such +commit(s) should be at the forefront to mitigate their impact in a +timely fashion: by pushing a followup commit to fix it (if possible), +or by reverting it to leave time to come up with a proper fix, and by +communicating with other developers about the problem. + +If these persons are unavailable to address the issue in time, other +committers are entitled to revert the commit(s), explaining in the +commit log and on the mailing list what the problem was, with the goal +of leaving time to the original committer, reviewer(s), and author(s) +to propose a way forward. + +Once the problem has been dealt with, it is the responsibility of +those involved to make sure the situation is understood. If you are +working to understand what happened, focus on gathering information +and avoid assigning any blame.
