Functions

func DescribeFacades

func DescribeFacades() []params.FacadeVersions

DescribeFacades returns the list of available Facades and their Versions

func IsMethodAllowedDuringUpgrade

func IsMethodAllowedDuringUpgrade(rootName, methodName string) bool

func NewAllWatcher

func NewAllWatcher(st *state.State, resources *common.Resources, auth common.Authorizer, id string) (interface{}, error)

NewAllWatcher returns a new API server endpoint for interacting with a watcher created by the WatchAll and WatchAllModels API calls.

Types

type EntitiesWatcher

type EntitiesWatcher interface {
	state.StringsWatcher

	// MapChanges maps the received strings to their according tag strings.
	// The EntityFinder interface representing state or a mock has to be
	// upcasted into the needed sub-interface of state for the real mapping.
	MapChanges(in []string) ([]string, error)
}

EntitiesWatcher defines an interface based on the StringsWatcher but also providing a method for the mapping of the received strings to the tags of the according entities.

type LoginValidator

type LoginValidator func(params.LoginRequest) error

LoginValidator functions are used to decide whether login requests are to be allowed. The validator is called before credentials are checked.

type Pinger

type Pinger interface {
	Ping()
	Stop() error
}

pinger describes a resource that can be pinged and stopped.

func NewPinger

func NewPinger(st *state.State, resources *common.Resources, authorizer common.Authorizer) (Pinger, error)

NewPinger returns an object that can be pinged by calling its Ping method. If this method is not called frequently enough, the connection will be dropped.

type Server

type Server struct {
	// contains filtered or unexported fields
}

Server holds the server side of the API.

func NewServer

func NewServer(s *state.State, lis net.Listener, cfg ServerConfig) (*Server, error)

NewServer serves the given state by accepting requests on the given listener, using the given certificate and key (in PEM format) for authentication.

The Server will close the listener when it exits, even if returns an error.

func (*Server) Dead

func (srv *Server) Dead() <-chan struct{}

Dead returns a channel that signals when the server has exited.

func (*Server) Kill

func (srv *Server) Kill()

Kill implements worker.Worker.Kill.

func (*Server) Stop

func (srv *Server) Stop() error

Stop stops the server and returns when all running requests have completed.

func (*Server) Wait

func (srv *Server) Wait() error

Wait implements worker.Worker.Wait.

type ServerConfig

type ServerConfig struct {
	Cert        []byte
	Key         []byte
	Tag         names.Tag
	DataDir     string
	LogDir      string
	Validator   LoginValidator
	CertChanged chan params.StateServingInfo

	// This field only exists to support testing.
	StatePool *state.StatePool
}

ServerConfig holds parameters required to set up an API server.

type SrvAllWatcher

type SrvAllWatcher struct {
	// contains filtered or unexported fields
}

SrvAllWatcher defines the API methods on a state.Multiwatcher. which watches any changes to the state. Each client has its own current set of watchers, stored in resources. It is used by both the AllWatcher and AllModelWatcher facades.

func (*SrvAllWatcher) Next

func (*SrvAllWatcher) Stop

func (w *SrvAllWatcher) Stop() error
