示例1: metadataUnchanged
// metadataUnchanged returns true if the content of metadata for stream in stor is the same
// as generatedMetadata, ignoring the "updated" attribute.
func metadataUnchanged(stor storage.Storage, stream string, generatedMetadata []byte) (bool, error) {
mdPath := ProductMetadataPath(stream)
filePath := path.Join(storage.BaseToolsPath, mdPath)
existingDataReader, err := stor.Get(filePath)
// If the file can't be retrieved, consider it has changed.
if err != nil {
return false, nil
}
defer existingDataReader.Close()
existingData, err := ioutil.ReadAll(existingDataReader)
if err != nil {
return false, err
}
// To do the comparison, we unmarshall the metadata, clear the
// updated value, and marshall back to a string.
existingMetadata, err := removeMetadataUpdated(existingData)
if err != nil {
return false, err
}
newMetadata, err := removeMetadataUpdated(generatedMetadata)
if err != nil {
return false, err
}
return existingMetadata == newMetadata, nil
}示例2: SignFileData
func SignFileData(stor storage.Storage, fileName string) error {
r, err := stor.Get(fileName)
if err != nil {
return err
}
defer r.Close()
fileData, err := ioutil.ReadAll(r)
if err != nil {
return err
}
signedName, signedContent, err := sstesting.SignMetadata(fileName, fileData)
if err != nil {
return err
}
err = stor.Put(signedName, strings.NewReader(string(signedContent)), int64(len(string(signedContent))))
if err != nil {
return err
}
return nil
