Each file in Fuchsia has a set of owners. These are tracked in files named
OWNERS. One of these files is present in the root of the repository, and many directories have their own
OWNERS files too.
OWNERS file lists a number of individuals (by their email address) who are familiar with and can provide code reviews for the contents of that directory.
It's important to have at least two individuals in an
OWNERS file. Having areas of Fuchsia with a single owner leads to single points of failure and having multiple owners ensures that knowledge and ownership is shared over areas of Fuchsia.
Fuchsia requires changes to have an
Code-Review +2 review, which anyone in the ‘OWNERS’ file can provide. In addition, many
OWNERS files contain a
* allowing anyone to provide such a
Gerrit has a “find owners” button that will list all the owners for all the files modified in a given change. More information on this is available on the Gerrit find-owners plugin page.
Fuchsia uses the Gerrit file syntax for
OWNERS files, with the addition of a comment indicating the default Monorail component to use when filing issues related to the contents of this directory.
