示例1: prepare

// prepare is the internal version of Prepare - it prepares the
// environment but does not open it.
func (p *environProvider) prepare(cfg *config.Config) (*config.Config, error) {
	ecfg, err := p.newConfig(cfg)
	if err != nil {
		return nil, err
	}
	p.mu.Lock()
	defer p.mu.Unlock()
	name := cfg.Name()
	if ecfg.stateId() != noStateId {
		return cfg, nil
	}
	// The environment has not been prepared,
	// so create it and set its state identifier accordingly.
	if ecfg.stateServer() && len(p.state) != 0 {
		for _, old := range p.state {
			panic(fmt.Errorf("cannot share a state between two dummy environs; old %q; new %q", old.name, name))
		}
	}
	state := newState(name, p.ops, p.statePolicy)
	p.maxStateId++
	state.id = p.maxStateId
	p.state[state.id] = state
	// Add the state id to the configuration we use to
	// in the returned environment.
