示例1: Read
// Read reads the snapshot named by snapname and returns the snapshot.
func Read(snapname string) (*raftpb.Snapshot, error) {
b, err := ioutil.ReadFile(snapname)
if err != nil {
log.Printf("snap: snapshotter cannot read file %v: %v", snapname, err)
return nil, err
}
var serializedSnap snappb.Snapshot
if err = serializedSnap.Unmarshal(b); err != nil {
log.Printf("snap: corrupted snapshot file %v: %v", snapname, err)
return nil, err
}
if len(serializedSnap.Data) == 0 || serializedSnap.Crc == 0 {
log.Printf("snap: unexpected empty snapshot")
return nil, ErrEmptySnapshot
}
crc := crc32.Update(0, crcTable, serializedSnap.Data)
if crc != serializedSnap.Crc {
log.Printf("snap: corrupted snapshot file %v: crc mismatch", snapname)
return nil, ErrCRCMismatch
}
var snap raftpb.Snapshot
if err = snap.Unmarshal(serializedSnap.Data); err != nil {
