port mapper gives out ports from 63000-65000 for the tests fix another race http test uses port.MustGetPort rbf: remove :0 port request ocd happy test fix for grpc listener address already in use test/disco allocates BindGRPC port from the port mapper dump stack on each GetPort verify each port is usable right away server/config.go has Config.Validate() now panic if gossip port is 0. validate server.Config fix another gossip port 0 builds quiet, don't dump stack on each port alloc builds happy linter even gossip fallback should not be zero but rather use the port mapper
