示例1: processService
func (context *statusContext) processService(service *state.Service) (status params.ServiceStatus) {
serviceCharmURL, _ := service.CharmURL()
status.Charm = serviceCharmURL.String()
status.Exposed = service.IsExposed()
status.Life = processLife(service)
latestCharm, ok := context.latestCharms[*serviceCharmURL.WithRevision(-1)]
if ok && latestCharm != serviceCharmURL.String() {
status.CanUpgradeTo = latestCharm
}
var err error
status.Relations, status.SubordinateTo, err = context.processServiceRelations(service)
if err != nil {
status.Err = err
return
}
networks, err := service.Networks()
if err != nil {
status.Err = err
return
}
var cons constraints.Value
if service.IsPrincipal() {
// Only principals can have constraints.
cons, err = service.Constraints()
if err != nil {
status.Err = err
return
}
}
// TODO(dimitern): Drop support for this in a follow-up.
if len(networks) > 0 || cons.HaveNetworks() {
// Only the explicitly requested networks (using "juju deploy
// <svc> --networks=...") will be enabled, and altough when
// specified, networks constraints will be used for instance
// selection, they won't be actually enabled.

Enabled: networks,
Disabled: append(cons.IncludeNetworks(), cons.ExcludeNetworks()...),
}
}

}示例2: assertConstraints
func (s *DeployLocalSuite) assertConstraints(c *gc.C, service *state.Service, expect constraints.Value) {
