This plugin provides a Prolog predicateadd_owner_approval/3 that appendslabel('Owner-Approval', need(_)) to a provided list.
Owner approval is determined based on OWNERS files located in the same repository. They are resolved against the state present in the existing master branch.
The OWNERS files are represented by the following YAML structure:
inherited:trueowners:-user-a@example.com-user-b@example.com
This translates to inheriting owner email address from any parent OWNER files and to allowuser-a@example.com anduser-b@example.com to approve the change.
The plugin analyzes the latest patch set by looking at each patch and building an OWNERS hierarchy. It stops once it finds an OWNERS file that has “inherited” set to false (by default it’s true.)
For example, imagine the following tree:
/OWNERS/example/src/main/OWNERS/example/src/main/java/com/example/foo/Foo.java/example/src/main/resources/config.properties/example/src/test/OWNERS/example/src/test/java/com/example/foo/FooTest.java
If you submit a patch set that changes/example/src/main/java/com/example/foo/Foo.java then the plugin will first open/example/src/main/OWNERS and if inherited is set to true combine it with the owners listed in/OWNERS.
If for each patch there is a reviewer who gave aCode-Review +2 then the plugin will not add any labels,otherwise it will addlabel('Owner-Approval', need(_)).
Here’s a sample rules.pl that uses this predicate to enable the submit rule.
submit_rule(S):-gerrit:default_submit(D),D=.. [submit | Ds],findall(U,gerrit:commit_label(label('Code-Review',2),U),Approvers),gerrit_owners:add_owner_approval(Approvers,Ds,A),S =.. [submit | A].There is a second plugin,gerrit-owners-autoassign which depends ongerrit-owners. It will automatically assignall of the owners to review a change when it's created or updated.
