Constants

View Source 
const CurrentFormat uint32 = 3

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.

Functions

func WriteExtensionPayload added in v0.47.0 

func WriteExtensionPayload(protoWriter protoio.Writer, payload []byte) error

WriteExtensionPayload writes an extension payload for current extension snapshotter.

Types

type ExtensionPayloadReader added in v0.47.0 

type ExtensionPayloadReader = func() ([]byte, error)

ExtensionPayloadReader read extension payloads, it returns io.EOF when reached either end of stream or the extension boundaries.

type ExtensionPayloadWriter added in v0.47.0 

type ExtensionPayloadWriter = func([]byte) error

ExtensionPayloadWriter is a helper to write extension payloads to underlying stream.

type ExtensionSnapshotter added in v0.45.2 

type ExtensionSnapshotter interface {
	// 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

	// SnapshotExtension writes extension payloads into the underlying protobuf stream.
	SnapshotExtension(height uint64, payloadWriter ExtensionPayloadWriter) error

	// RestoreExtension restores an extension state snapshot,
	// the payload reader returns `io.EOF` when reached the extension boundaries.
	RestoreExtension(height uint64, format uint32, payloadReader ExtensionPayloadReader) error
}

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

	// PruneSnapshotHeight prunes the given height according to the prune strategy.
	// If PruneNothing, this is a no-op.
	// If other strategy, this height is persisted until it is
	// less than <current height> - KeepRecent and <current height> % Interval == 0
	PruneSnapshotHeight(height int64)

	// SetSnapshotInterval sets the interval at which the snapshots are taken.
	// It is used by the store that implements the Snapshotter interface
	// to determine which heights to retain until after the snapshot is complete.
	SetSnapshotInterval(snapshotInterval uint64)

	// Restore restores a state snapshot, taking the reader of protobuf message stream as input.
	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).
