In most cases FirewallPluginDb has opened reader/writer contexts for its db access, but not in all. Once instance in which this can fail is when the port AFTER_UPDATE event handler is called. This method might call get_fwg_attached_to_port() outside of a transaction, which currently automatically opens one. This will explicitly fail when a transaction guard is hit with an exception: RuntimeError: Must not be called in a transaction To avoid this, we add a reader context to get_fwg_attached_to_port() and while we're at it we're adding this to all FirewallPluginDb methods that do a model_query db query - just to be on the safe side.
