+# Summary
+[summary]: #summary
+
+Require pull requests for all Nixpkgs commits.
+
+# Motivation
+[motivation]: #motivation
+
+There are currently 197 people with commit access to Nixpkgs, all of whom can push directly to any branch without a pull request.
+Such pushes generally[^1] do not notify anybody and do not trigger CI.
+
+[^1]: There's no GitHub mechanism that takes care of notifying other people and there's no builtin way to get notified for new commits linked to [the direct push issue](https://github.com/NixOS/nixpkgs/issues/118661), but third-party tooling could be implemented to get notified explicitly for direct pushes
+
+This makes such commits susceptible to:
+- Be anonymous[^2]
+- Include malicious code
+- Be broken
+- Have poor code quality
+
+[^2]: GitHub does not require committers to match the pushing GitHub account, [here's](https://github.com/infinisil/github-test/commit/0553a1afe8ee38d45ef38c7055a7b6c3ee08f3d3) an example.
+
+While requiring pull requests isn't a panacea, it does help by:
+- Running CI (though there's no requirement for it to succeed, see [future work][future])
+- Requesting reviews from [Nixpkgs maintainers](https://github.com/NixOS/rfcs/pull/39) via CI
+- Requesting reviews from [code owners](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners)
+- Tying commits to a GitHub account
+- Being discoverable in the pull request list using various filterable and sortable metadata such as (manually and [automatically](https://github.com/NixOS/nixpkgs/blob/e0d40b94732d0a077ea8e409d394bcd36750584e/.github/labeler.yml) assigned) [labels](https://github.com/NixOS/nixpkgs/labels), update time, authors, reviews, etc.
+
+
+# Detailed design
+[design]: #detailed-design
+
+Turn on GitHub's "Require a pull request before merging" [branch protection rule](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/managing-a-branch-protection-rule#creating-a-branch-protection-rule) for all branches whose commits get propagated into channels.
+This includes:
+- `master`: Used for unstable channels and branched into new release branches
+- `release-*`: Used for stable channels
+
+Staging branches are intentionally not included, because they will already require a pull request when they inevitably need to get merged into one of the above branches.
+The same applies to similar long-term branches like `haskell-packages`.
+
+A NixOS GitHub organization owner needs to implement this change and should therefore review this proposal.
+
+## Disable the direct push detection workflow
+
+There is a [GitHub Actions workflow to detect directly pushed commits](https://github.com/NixOS/nixpkgs/blob/0b411c1e040870e89a3e598437e708979137b665/.github/workflows/direct-push.yml).
+When detected, it creates a comment in the commit pointing out that this is discouraged and linking to [this issue](https://github.com/NixOS/nixpkgs/issues/118661), where it's easy to see all direct pushes.
+The script occasionally has false positives[^3], which creates some unnecessary commit comment notifications.
+
+[^3]: https://github.com/NixOS/nixpkgs/issues/240314
+
+With this proposal accepted it won't be possible to directly push commits anymore, making that workflow unnecessary.
+It can be removed and the above two issues can be closed.
+
+# Examples and Interactions
+[examples-and-interactions]: #examples-and-interactions
+
+## Direct pushes listing
+
+Out of the 112217 commits to master in the last year[^4], _at most_ 58 (0.0517%) of them were direct pushes.
+
+[^4]: Unix epoch 1658361600 to 1689897600
+
+To determine whether a commit was pushed directly, the GitHub API was queried for pull requests associated with that commit (see [`associatedPullRequests`](https://docs.github.com/en/graphql/reference/objects#commit)).
+If this list includes a merged pull request to the Nixpkgs master branch, the commit is known to be merged with a pull request.
+Otherwise the commit could be directly pushed or be a false positives, which is why the above count is only an upper bound.
+All obvious false positives ([example](https://github.com/NixOS/nixpkgs/commit/b09d18903c24b8aca88100df86aa2fdd5f05dfcd)) have been removed from this count and listing already.

+
+## Emergency changes
+
+Sometimes channels have blocking breakages and need to be fixed as soon as possible (citation needed).
+Currently this can be done with direct pushes, but a pull request will be required with this proposal.
+The time required to fix such breakages however is barely affected: Since there is currently no requirement for pull requests to be approved or pass CI, they can get merged immediately after opening if necessary.
+
+## Staging workflow
+
+The staging workflow is not affected because it [already uses pull requests](https://github.com/NixOS/nixpkgs/pull/241951) for all merges into the affected branches.
+
+# Drawbacks
+[drawbacks]: #drawbacks
+
+- Even trivial changes that don't need a review now require a pull request, which takes more effort and creates noise for reviewers.
+- It takes slightly longer to push a quick fix in emergency situations.
+
+# Alternatives
+[alternatives]: #alternatives
+
+- It would be possible to implement a third-party interface to de-anonymize future commits (even if pushed directly to master) using the [push event GitHub webhook](https://docs.github.com/en/webhooks-and-events/webhooks/webhook-events-and-payloads#push), which includes the `sender` field to match the pushing GitHub user.
+  - This would not solve the other problems with direct pushes though: It still wouldn't notify others, trigger CI or be discoverable.
+
+# Prior art
+[prior-art]: #prior-art
+
+The previous [RFC 79](https://github.com/NixOS/rfcs/pull/79) attempted to do the same, but:
+- It had a mistaken estimate for the percentage of direct master commits, calculating it to be 46.85% in the last year.
+  The mistake was assuming that all non-merge commits were direct pushes.
+  This made it seem like the change was much more impactful than it actually would've been.
+- It was too ambitious by also proposing to require accepting reviews for all pull requests.
+
+# Unresolved questions
+[unresolved]: #unresolved-questions
+
+# Future work
+[future]: #future-work
+More restrictions could be implemented in the future:
+- Require all pull requests to have at least one approval, therefore preventing people from merging their own pull requests (it's not possible to approve your own pull request)
+- Require an approval by a code owner, properly establishing code ownership over all parts of Nixpkgs
+- Require CI to pass, maybe using GitHub's new [merge queue's](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/managing-a-merge-queue)
