Functions

func Configure

func Configure(st *state.State, snapName string, patch map[string]interface{}, flags int) *state.TaskSet

Configure returns a taskset to apply the given configuration patch.

func ConfigureHookTimeout

func ConfigureHookTimeout() time.Duration

func ConfigureInstalled

func ConfigureInstalled(st *state.State, snapName string, patch map[string]interface{}, flags int) (*state.TaskSet, error)

ConfigureInstalled returns a taskset to apply the given configuration patch for an installed snap. It returns snap.NotInstalledError if the snap is not installed.

func ContextTransaction

func ContextTransaction(context *hookstate.Context) *config.Transaction

ContextTransaction retrieves the transaction cached within the context (and creates one if it hasn't already been cached).

func EarlyConfig

func EarlyConfig(st *state.State, preloadGadget func() (sysconfig.Device, *gadget.Info, error)) error

EarlyConfig performs any needed early configuration handling during managers' startup, it is exposed as a hook to devicestate for invocation. preloadGadget if set will be invoked if the system is not yet seeded or configured, it should either return ErrNoState, or return the gadget.Info for the to-be-seeded gadget and details about the model/device as sysconfig.Device.

func Init

func Init(st *state.State, hookManager *hookstate.HookManager) error

func MockConfigcoreRun

func MockConfigcoreRun(f func(sysconfig.Device, config.Conf) error) (restore func())

func RemapSnapFromRequest

func RemapSnapFromRequest(snapName string) string

RemapSnapFromRequest renames a snap as received from an API request

func RemapSnapToResponse

func RemapSnapToResponse(snapName string) string

RemapSnapToResponse renames a snap as about to be sent from an API response
