Question

we want to use gerrit for code reviews but we are missing some settings in the webview.

• is it possible to forbid committers to review/verify their own
  commits?
• is it possible that two reviewers give +1 an accumulate it
  to a +2 so it can be submitted?

thanks

Answer 1

• is it possible to forbid committers to review/verify their own commits?

Yes, setup autobuild to verify all commits. You can set this up by using the Gerrit Trigger for Jenkins or gReview for Bamboo. That way nobody has to verify commits. Additionally, you can setup superusers so only a select group can actually merge the final reviewed change.

is it possible that two reviewers give +1 an accumulate it to a +2 so
it can be submitted?

No, two +1 doesn’t make the +2 necessary to submit. Here’s what the doc says:

The label that the reviewer selects determines what can happen next.
The +1 and -1 level are just an opinion where as the +2 and -2 levels
are allowing or blocking the change. In order for a change to be
accepted it must have at least one +2 and no -2 votes. Although these
are numeric values, they in no way accumulate; two +1s do not equate
to a +2.
