The following section is a draft, and the policy for reviewing is still
|
|
being discussed in issues such as
|
|

The Nixpkgs project receives a fairly high number of contributions via GitHub
|
|
pull requests. Reviewing and approving these is an important task and a way
|
|
to contribute to the project.
|
|
</para>
|
|
<para>
|
|
The high change rate of Nixpkgs makes any pull request that remains open for
|
|
too long subject to conflicts that will require extra work from the submitter
|
|
or the merger. Reviewing pull requests in a timely manner and being
|
|
responsive to the comments is the key to avoid this issue. GitHub provides
|
|
sort filters that can be used to see the
|
|
<link
|
|
xlink:href="https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+is%3Aopen+sort%3Aupdated-desc">most
|
|
recently</link> and the
|
|
<link
|
|
xlink:href="https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+is%3Aopen+sort%3Aupdated-asc">least
|
|
recently</link> updated pull requests. We highly encourage looking at

<para>

|
When reviewing a pull request, please always be nice and polite.
|
|
Controversial changes can lead to controversial opinions, but it is important
|
|
to respect every community member and their work.
|

</para>
|
|
<para>
|
|
GitHub provides reactions as a simple and quick way to provide feedback to
|
|
pull requests or any comments. The thumb-down reaction should be used with
|
|
care and if possible accompanied with some explanation so the submitter has
|
|
directions to improve their contribution.
|
|
</para>
|
|
<para>
|
|
pull request reviews should include a list of what has been reviewed in a
|
|
comment, so other reviewers and mergers can know the state of the review.

All the review template samples provided in this section are generic and

name and the source hash.

If you consider having enough knowledge and experience in a topic and would
|
|
like to be a long-term reviewer for related submissions, please contact the
|
|
current reviewers for that topic. They will give you information about the
|
|
reviewing process. The main reviewers for a topic can be hard to find as
|
|
there is no list, but checking past pull requests to see who reviewed or
|
|
git-blaming the code to see who committed to that topic can give some hints.

In a case a contributor definitively leaves the Nix community, they should
|
|
create an issue or post on
|
|
<link
|
|
xlink:href="https://discourse.nixos.org">Discourse</link> with
|
|
references of packages and modules they maintain so the maintainership can
|
|
be taken over by other contributors.
