Constants

View Source 
const CurrentFormat uint32 = 1

CurrentFormat is the currently used format for snapshots. Snapshots using the same format must be identical across all nodes for a given height, so this must be bumped when the binary snapshot output changes.

Variables

	// ErrUnknownFormat is returned when an unknown format is used.
	ErrUnknownFormat = errors.New("unknown snapshot format")

	// ErrChunkHashMismatch is returned when chunk hash verification failed.
	ErrChunkHashMismatch = errors.New("chunk hash verification failed")

	// ErrInvalidMetadata is returned when the snapshot metadata is invalid.
	ErrInvalidMetadata = errors.New("invalid snapshot metadata")

Functions

func WriteExtensionItem added in v0.46.0

Types

type ExtensionSnapshotter added in v0.46.0 

type ExtensionSnapshotter interface {
	Snapshotter

	// SnapshotName returns the name of snapshotter, it should be unique in the manager.
	SnapshotName() string

	// SnapshotFormat returns the default format the extension snapshotter use to encode the
	// payloads when taking a snapshot.
	// It's defined within the extension, different from the global format for the whole state-sync snapshot.
	SnapshotFormat() uint32

	// SupportedFormats returns a list of formats it can restore from.
	SupportedFormats() []uint32
}

ExtensionSnapshotter is an extension Snapshotter that is appended to the snapshot stream. ExtensionSnapshotter has an unique name and manages it's own internal formats.

type Snapshotter 

type Snapshotter interface {
	// Snapshot writes snapshot items into the protobuf writer.
	Snapshot(height uint64, protoWriter protoio.Writer) error

	// Restore restores a state snapshot from the protobuf items read from the reader.
	// If the ready channel is non-nil, it returns a ready signal (by being closed) once the
	// restorer is ready to accept chunks.
	Restore(height uint64, format uint32, protoReader protoio.Reader) (SnapshotItem, error)
}

Snapshotter is something that can create and restore snapshots, consisting of streamed binary chunks - all of which must be read from the channel and closed. If an unsupported format is given, it must return ErrUnknownFormat (possibly wrapped with fmt.Errorf).
