Functions

func SpawnDaemon 

func SpawnDaemon(cfg *config.Instance) (cleanup func(), err error)

SpawnDaemon spawns a daemon subprocess for service isolation (e.g., TUI mode). It waits for the service API to become available and returns a cleanup function. The cleanup function sends SIGTERM and waits for graceful shutdown with timeout. Returns a no-op cleanup function if service was already running.

Types

type Service 

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

func NewService 

func NewService(args ServiceArgs) (*Service, error)

func (*Service) Pid 

func (s *Service) Pid() (int, error)

Pid returns the process ID of the current running service daemon.

func (*Service) Restart 

func (s *Service) Restart() error

Restart is intentionally idempotent: if Running reports no live PID, Stop and waitForPIDExit are skipped and Start is called directly. When a PID is still active, Restart follows the full Stop -> waitForPIDExit -> Start sequence so pidRunning has confirmed the old process is gone before the replacement starts.

func (*Service) Running 

func (s *Service) Running() (bool, error)

Running returns true if the service is running.

func (*Service) ServiceHandler 

func (s *Service) ServiceHandler(cmd *string) error

func (*Service) Start 

func (s *Service) Start() error

Start a new service daemon in the background.

func (*Service) Stop 

func (s *Service) Stop() error

Stop the service daemon.

func (*Service) WaitForAPI 

func (s *Service) WaitForAPI(cfg *config.Instance, maxWait, checkInterval time.Duration) error

WaitForAPI waits for the service API to become available with health monitoring. Returns nil if API became available, error if timeout or process crashed.

type ServiceArgs 

type ServiceArgs struct {
	Platform platforms.Platform
	Config   *config.Instance
	Entry    ServiceEntry
	NoDaemon bool
}

type ServiceEntry 

type ServiceEntry func() (*service.StartResult, error)
