Functions

func SignExisting

func SignExisting(src io.Reader, dst io.Writer, key []byte, overwrite bool) error

Special fast-track to just sign, nothing else. This skips all the expensive and complicated repacking, and simply adds the manifest.sig file.

func WriteSignature

func WriteSignature(tw *tar.Writer, message []byte,
	signer artifact.Signer) error

Types

type Updates

type Updates struct {
	// Both of these are indexed the same, so Augment at index X corresponds
	// to Update at index X.
	Updates  []handlers.Composer
	Augments []handlers.Composer
}

type WriteArtifactArgs

type WriteArtifactArgs struct {
	Format            string
	Version           int
	Devices           []string
	Name              string
	Updates           *Updates
	Scripts           *artifact.Scripts
	Depends           *artifact.ArtifactDepends
	Provides          *artifact.ArtifactProvides
	TypeInfoV3        *artifact.TypeInfoV3
	MetaData          map[string]interface{} // Generic JSON
	AugmentTypeInfoV3 *artifact.TypeInfoV3
	AugmentMetaData   map[string]interface{} // Generic JSON
}

type Writer

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

Writer provides on the fly writing of artifacts metadata file used by the Mender client and the server.

func NewWriter

func NewWriter(w io.Writer, c artifact.Compressor) *Writer

func NewWriterSigned

func NewWriterSigned(w io.Writer, c artifact.Compressor, manifestChecksumStore artifact.Signer) *Writer

func (*Writer) WriteArtifact

func (aw *Writer) WriteArtifact(args *WriteArtifactArgs) (err error)
