Constants ¶

const ( // DefaultServiceName is the default Windows service name. DefaultServiceName = "WarpDL" // DefaultDisplayName is the default Windows service display name. DefaultDisplayName = "WarpDL Download Manager" // DefaultDescription is the default Windows service description. DefaultDescription = "High-performance parallel download manager" )
Service name constants for Windows service registration.
Variables ¶

var ( // ErrAlreadyRunning is returned when Start() is called on a running daemon. ErrAlreadyRunning = errors.New("daemon is already running") // ErrNotRunning is returned when Shutdown() is called on a stopped daemon. ErrNotRunning = errors.New("daemon is not running") // ErrShutdownTimeout is returned when shutdown exceeds the configured timeout. ErrShutdownTimeout = errors.New("shutdown timed out") )
Sentinel errors for the daemon runner.

Types ¶
type Config ¶
type Config struct {
// ServiceName is the Windows service name.
ServiceName string
// DisplayName is the Windows service display name.
DisplayName string
// Port is the TCP port for fallback connections.
// Use 0 for an ephemeral port.
Port int
// ConfigDir is the directory for configuration files.
ConfigDir string
// ShutdownTimeout is the maximum time to wait for graceful shutdown.
// A zero value means no timeout.
ShutdownTimeout time.Duration
}
Config holds the configuration for the daemon runner.
type Dependencies ¶
type Dependencies struct {
// ListenerFactory creates network listeners.
// If nil, net.Listen is used.
ListenerFactory func(network, address string) (net.Listener, error)
// ShutdownFunc is called during shutdown to clean up resources.
// If nil, no cleanup function is called.
ShutdownFunc func() error
}
Dependencies holds the external dependencies for the daemon runner. This enables dependency injection for testing.
type Runner ¶
type Runner struct {
// contains filtered or unexported fields
}
Runner manages the daemon lifecycle.
func New ¶
func New(config *Config, deps *Dependencies) *Runner
New creates a new daemon runner with the given configuration and dependencies. If config is nil, default values are used. If deps is nil, default dependencies (using net.Listen) are used.
