[ovirt-devel] Is only master branch of ovirt-engine analyzed on coverity scan?

I see the github project ovirt-engine (https://github.com/oVirt/ovirt-engine) is registered on Coverity Scan for routine analysis (https://scan.coverity.com/projects/ovirt-engine?tab=project_settings). My question is - 1) do we only build and analyze the master branch on Coverity? 1a) If yes, why do we not analyze the other branches? 1b) If no, how to detect which alert on coverity is for which branch? Thanks, Nasif
