pull request
A term for a request on GitHub to merge some changes into a codebase. Pull requests are the primary place where code review happens for GitHub projects.
Abbreviation for a request to review a piece of code.
Abbreviation for passing a code review. In some cases, the r+ is conditional on additional changes being made, but subsequent review is not necessary after making them.
Abbreviation for failing a code review. This usually means that more work is needed rather than rejecting the code outright. After the requested changes are made, another code review is required.
