Swingset will soon change from "all dynamic vats are metered" to "dynamic vats are unmetered by default", so set "metered: true" to retain the current behavior for ZCF vats.
In addition, metering is going to be removed from the "local" (Node.js) vat-worker, so "metered: true" will require "xs-worker" (xsnap) instead. This changes the
tests/swingsetTests
runners to use xs-worker.Note that this upcoming change means any application which uses Zoe to spawn ZCF vats must run with
config.defaultManagerType='xs-worker'
, otherwise vat creation will fail when Zoe asks for a metered vat. Our two primary applications (the chain and the solo machine) both do this already.refs #3518
