Types

type Config 

type Config struct {

	// StateDir is the directory to use for state.
	StateDir string `protobuf:"bytes,1,opt,name=state_dir,json=stateDir,proto3" json:"stateDir,omitempty"`
	// DistDir is the directory to use for plugin distribution files

	// contains filtered or unexported fields
}

Config is the Process PluginHost controller configuration.

func NewConfig 

func NewConfig(
	stateDir,
	distDir string,

func (x *Config) MarshalProtoJSON(s *json.MarshalState)

MarshalProtoJSON marshals the Config message to JSON.

func (*Config) MarshalProtoText 

func (x *Config) MarshalProtoText() string

func (*Config) MarshalToSizedBufferVT 

func (m *Config) MarshalToSizedBufferVT(dAtA []byte) (int, error)

func (*Config) MarshalToVT

func (*Config) UnmarshalJSON 

func (x *Config) UnmarshalJSON(b []byte) error

UnmarshalJSON unmarshals the Config from JSON.

func (*Config) UnmarshalProtoJSON 

func (x *Config) UnmarshalProtoJSON(s *json.UnmarshalState)

UnmarshalProtoJSON unmarshals the Config message from JSON.

func (*Config) UnmarshalVT 

func (m *Config) UnmarshalVT(dAtA []byte) error

func (*Config) Validate 

func (c *Config) Validate() error

Validate validates the configuration. This is a cursory validation to see if the values "look correct."

type Controller 

type Controller = host_controller.Controller

Controller is the plugin host controller tytpe.

type Factory 

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

Factory constructs a plugin host.

func NewFactory 

func NewFactory(bus bus.Bus) *Factory

NewFactory builds the factory.

func (*Factory) Construct 

func (t *Factory) Construct(
	ctx context.Context,
	conf config.Config,
	opts controller.ConstructOpts,
) (controller.Controller, error)

Construct constructs the associated controller given configuration.

func (*Factory) ConstructConfig 

func (t *Factory) ConstructConfig() config.Config

ConstructConfig constructs an instance of the controller configuration.

func (*Factory) GetConfigID 

func (t *Factory) GetConfigID() string

GetConfigID returns the configuration ID for the controller.

func (*Factory) GetControllerID 

func (t *Factory) GetControllerID() string

GetControllerID returns the unique ID for the controller.

func (*Factory) GetVersion 

func (t *Factory) GetVersion() semver.Version

GetVersion returns the version of this controller.

type ProcessHost 

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

ProcessHost implements the plugin host with native processes.

func NewProcessHost 

func NewProcessHost(le *logrus.Entry, stateDir, distDir string) (*ProcessHost, error)

NewProcessHost constructs a new ProcessHost.

func NewProcessHostController 

func NewProcessHostController(
	le *logrus.Entry,
	b bus.Bus,
	c *Config,
) (*host_controller.Controller, *ProcessHost, error)

NewProcessHostController constructs the ProcessHost and PluginHost controller.

func (*ProcessHost) DeletePlugin 

func (h *ProcessHost) DeletePlugin(ctx context.Context, pluginID string) error

DeletePlugin clears cached plugin data for the given plugin ID.

func (*ProcessHost) Execute 

func (h *ProcessHost) Execute(ctx context.Context) error

Execute is a stub as the process host does not need a global management goroutine.

func (*ProcessHost) ExecutePlugin 

func (h *ProcessHost) ExecutePlugin(
	rctx context.Context,
	pluginID, instanceKey, entrypoint string,
	pluginDist, pluginAssets *unixfs.FSHandle,
	hostMux srpc.Mux,
	rpcInit plugin_host.PluginRpcInitCb,
) error

ExecutePlugin executes the plugin with the given ID. If the plugin was already initialized, existing state can be reused. The plugin should be stopped if/when the function exits. Return ErrPluginUninitialized if the plugin was not ready. Should expect to be called only once (at a time) for a plugin ID. pluginDist contains the plugin distribution files (binaries and assets).

func (*ProcessHost) GetPlatformId
