Types ¶
type ArtifactRootfsReader ¶
type ArtifactRootfsReader struct {
// contains filtered or unexported fields
}
func NewArtifactExtractor ¶
func NewArtifactExtractor() ArtifactRootfsReader
func (*ArtifactRootfsReader) Close ¶
func (e *ArtifactRootfsReader) Close() error
Close the artifact file
func (*ArtifactRootfsReader) Extract ¶
func (e *ArtifactRootfsReader) Extract() error
Extract the contents of the artifact You MUST call Extract() from a different goroutine than the one reading rootfs data using the Reader().
func (*ArtifactRootfsReader) Open ¶
func (e *ArtifactRootfsReader) Open(path string) error
Open an artifact for extraction
func (*ArtifactRootfsReader) PayloadSize ¶
func (e *ArtifactRootfsReader) PayloadSize() int64
Returns the file size of the extracted rootfs image
func (*ArtifactRootfsReader) Reader ¶
func (e *ArtifactRootfsReader) Reader() *io.PipeReader
Returns a reader for the contents of the rootfs image contained in the artifact
type UpdateFileStorer ¶
type UpdateFileStorer struct {
FileSize int64
FileContentReader *io.PipeReader
// contains filtered or unexported fields
}
Custom UpdateStore for extracting files from artifacts This is required in order to extract the update files (i.e, the rootfs image) from an artifact using the `areader`, for the purposes of calculating the delta patch between a base and target artifacts. This supports only extracting a single file! Multi-file updates are not supported.
func NewUpdateFileStorer ¶
func NewUpdateFileStorer() UpdateFileStorer
func (UpdateFileStorer) FinishStoreUpdate ¶
func (m UpdateFileStorer) FinishStoreUpdate() error
func (*UpdateFileStorer) Initialize ¶
func (m *UpdateFileStorer) Initialize(artifactHeaders, artifactAugmentedHeaders artifact.HeaderInfoer, payloadHeaders handlers.ArtifactUpdateHeaders) error
func (UpdateFileStorer) PrepareStoreUpdate ¶
func (m UpdateFileStorer) PrepareStoreUpdate() error
func (*UpdateFileStorer) StoreUpdate ¶
type UpdateFileStorerFactory ¶
type UpdateFileStorerFactory struct {
// contains filtered or unexported fields
}
Required factory object for calling `SetUpdateStorerProducer` method on installer handlers
func NewUpdateFileStorerFactory ¶
func NewUpdateFileStorerFactory(storer *UpdateFileStorer) UpdateFileStorerFactory
func (UpdateFileStorerFactory) NewUpdateStorer ¶
func (f UpdateFileStorerFactory) NewUpdateStorer(updateType *string, payloadNum int) (handlers.UpdateStorer, error)
