test out the patch set and opine on the technical merits of the patch. Project
maintainers take into account the peer review when determining if there is
consensus to merge a pull request (remember that discussions may have been

+
+#### Conceptual Review
+
+A review can be a conceptual review, where the reviewer leaves a comment
+ * `Concept (N)ACK`, meaning "I do (not) agree in the general goal of this pull
+ request",
+ * `Approach (N)ACK`, meaning `Concept ACK`, but "I do (not) agree with the
+ approach of this change".
+
+A `NACK` needs to include a rationale why the change is not worthwhile.
+NACKs without accompanying reasoning may be disregarded.
+
+#### Code Review
+
+After conceptual agreement on the change, code review can be provided. It is
+starting with `ACK BRANCH_COMMIT`, where `BRANCH_COMMIT` is the top of the
+topic branch. The review is followed by a description of how the reviewer did
+the review. The following
language is used within pull-request comments:
- - (t)ACK means "I have tested the code and I agree it should be merged", involving
+ - "I have tested the code", involving
change-specific manual testing in addition to running the unit and functional
tests, and in case it is not obvious how the manual testing was done, it should
be described;
- - NACK means "I disagree this should be merged", and must be accompanied by
- sound technical justification (or in certain cases of copyright/patent/licensing
- issues, legal justification). NACKs without accompanying reasoning may be
- disregarded;
- - utACK means "I have not tested the code, but I have reviewed it and it looks
+ - "I have not tested the code, but I have reviewed it and it looks
OK, I agree it can be merged";
- - Concept ACK means "I agree in the general principle of this pull request";
- Nit refers to trivial, often non-blocking issues.
-Reviewers should include the commit hash which they reviewed in their comments.
