Functions

func DeployResources

func DeployResources(
	applicationID string,
	chID charmstore.CharmID,
	csMac *macaroon.Macaroon,
	filesAndRevisions map[string]string,
	resources map[string]charmresource.Meta,
	conn base.APICallCloser,
) (ids map[string]string, err error)

DeployResources uploads the bytes for the given files to the server and creates pending resource metadata for the all resource mentioned in the metadata. It returns a map of resource name to pending resource IDs.

func NewAPIClient

func NewAPIClient(apiCaller base.APICallCloser) (*client.Client, error)

NewAPIClient is mostly a copy of the newClient code in component/all/resources.go. It lives here because it simplifies this code immensely.

func NewLatestCharmHandler

func NewLatestCharmHandler(st *state.State) (charmrevisionupdater.LatestCharmHandler, error)

NewLatestCharmHandler returns a LatestCharmHandler that uses the given Juju state.

func NewResourceOpener

func NewResourceOpener(st *corestate.State, unitName string) (opener resource.Opener, err error)

NewResourceOpener returns a new resource.Opener for the given unit.

The caller owns the State provided. It is the caller's responsibility to close it.

TODO(mjs): This is the entry point for a whole lot of untested shim code in this package. At some point this should be sorted out.

type DeployResourcesFunc

type DeployResourcesFunc func(
	applicationID string,
	chID charmstore.CharmID,
	csMac *macaroon.Macaroon,
	filesAndRevisions map[string]string,
	resources map[string]charmresource.Meta,
	conn base.APICallCloser,
) (ids map[string]string, err error)

DeployResourcesFunc is the function type of DeployResources.
