示例1: assertEnvironDestroyed
func assertEnvironDestroyed(c *gc.C, env environs.Environ, store configstore.Storage) {
_, err := store.ReadInfo(env.Name())
c.Assert(err, jc.Satisfies, errors.IsNotFound)
_, err = env.Instances([]instance.Id{"invalid"})
c.Assert(err, gc.ErrorMatches, "environment has been destroyed")
}示例2: StateInfo
// StateInfo is a reusable implementation of Environ.StateInfo, available to
// providers that also use the other functionality from this file.
func StateInfo(env environs.Environ) (*state.Info, *api.Info, error) {
st, err := bootstrap.LoadState(env.Storage())
if err != nil {
return nil, nil, err
}
config := env.Config()
if _, hasCert := config.CACert(); !hasCert {
return nil, nil, fmt.Errorf("no CA certificate in environment configuration")
}
// Wait for the addresses of at least one of the instances to become available.
logger.Debugf("waiting for addresses of state server instances %v", st.StateInstances)
var addresses []string
for a := LongAttempt.Start(); len(addresses) == 0 && a.Next(); {
insts, err := env.Instances(st.StateInstances)
if err != nil && err != environs.ErrPartialInstances {
logger.Debugf("error getting state instances: %v", err.Error())
return nil, nil, err
}
addresses = getAddresses(insts)
}
if len(addresses) == 0 {
return nil, nil, fmt.Errorf("timed out waiting for addresses from %v", st.StateInstances)
}
stateInfo, apiInfo := getStateInfo(config, addresses)
return stateInfo, apiInfo, nil
}
