	GetConnName() string
	SendInput(input *BlockInputUnion) error
}

Controller interface that all block controllers must implement

func MakeDurableShellController added in v0.14.0 

func MakeDurableShellController(tabId string, blockId string, controllerType string, connName string) Controller

func MakeShellController added in v0.11.6 

func MakeShellController(tabId string, blockId string, controllerType string, connName string) Controller

Constructor that returns the Controller interface

func MakeTsunamiController added in v0.11.6 

func MakeTsunamiController(tabId string, blockId string, connName string) Controller

type DurableShellController added in v0.14.0 

type DurableShellController struct {
	Lock *sync.Mutex

	ControllerType string
	TabId          string
	BlockId        string
	ConnName       string
	BlockDef       *waveobj.BlockDef
	VersionTs      utilds.VersionTs

	InputSessionId string // random uuid

	JobId           string
	LastKnownStatus string
	// contains filtered or unexported fields
}

func (*DurableShellController) GetConnName added in v0.14.0 

func (dsc *DurableShellController) GetConnName() string

func (*DurableShellController) GetRuntimeStatus added in v0.14.0 

func (dsc *DurableShellController) GetRuntimeStatus() *BlockControllerRuntimeStatus

func (*DurableShellController) SendInput added in v0.14.0 

func (dsc *DurableShellController) SendInput(inputUnion *BlockInputUnion) error

func (*DurableShellController) Start added in v0.14.0 

func (dsc *DurableShellController) Start(ctx context.Context, blockMeta waveobj.MetaMapType, rtOpts *waveobj.RuntimeOpts, force bool) error

Start initializes or reconnects to a durable shell for the block. Logic: - If block has no existing jobId: starts a new job and attaches it - If block has existing jobId with running job manager: reconnects to existing job - If block has existing jobId with non-running job manager:

  • force=true: detaches old job and starts new one
  • force=false: returns without starting (leaves block unstarted)

After establishing jobId, ensures job connection is active (reconnects if needed)
