For many teams it is important to customize the conditions that make a change submittable (e.g. to enforce non-author code reviews). The way to do this in Gerrit is via labels and submit rules.
In this talk I explain how labels and submit rules work and what you can do with them.
For submit rules the focus is on Prolog-less submit rules which are based on a new extension point. Using this extension point to implement submit rules is a good alternative to writing Prolog submit rules which often cause trouble because most people are not familiar enough with Prolog. I will show an example implementation of a Prolog-less submit rule and explain how you can develop your own custom submit rules.
