Functions

func CopyFile

func CopyFile(srcPath, dstPath string) (err error)

CopyFile atomically copies a file using the update registry's tmp dir.

func DelayedRestart

func DelayedRestart(delay time.Duration)

DelayedRestart triggers a restart of the application by shutting down the module system gracefully and returning with RestartExitCode. The restart may be further delayed by up to 10 minutes by the internal task scheduling system. This only works if the process is managed by portmaster-start.

func DisableUpdateSchedule

func DisableUpdateSchedule() error

DisableUpdateSchedule disables the update schedule. If called, updates are only checked when TriggerUpdate() is called.

func GetFile

func GetFile(identifier string) (*updater.File, error)

GetFile returns the latest generic file identified by the given identifier.

func GetPlatformFile

func GetPlatformFile(identifier string) (*updater.File, error)

GetPlatformFile returns the latest platform specific file identified by the given identifier.

func RestartNow

func RestartNow()

RestartNow immediately executes a restart. This only works if the process is managed by portmaster-start.

func TriggerRestartIfPending

func TriggerRestartIfPending()

TriggerRestartIfPending triggers an automatic restart, if one is pending. This can be used to prepone a scheduled restart if the conditions are preferable.

func TriggerUpdate

func TriggerUpdate() error

TriggerUpdate queues the update task to execute ASAP.
