示例1: generateTimestamp
// generateTimestamp generates a new timestamp from the previous one in the store - this assumes all
// the other roles have already been set on the repo, and will set the generated timestamp on the repo as well
func generateTimestamp(gun string, builder tuf.RepoBuilder, store storage.MetaStore) (*storage.MetaUpdate, error) {
var prev *data.SignedTimestamp
_, currentJSON, err := store.GetCurrent(gun, data.CanonicalTimestampRole)
switch err.(type) {
case nil:
prev = new(data.SignedTimestamp)
if err := json.Unmarshal(currentJSON, prev); err != nil {
logrus.Error("Failed to unmarshal existing timestamp for GUN ", gun)
return nil, err
}
case storage.ErrNotFound:
break // this is the first timestamp ever for the repo
default:
return nil, err
}
meta, ver, err := builder.GenerateTimestamp(prev)
switch err.(type) {
case nil:

case signed.ErrInsufficientSignatures, signed.ErrNoKeys:
