示例1: CreateIntentForCollection

// CreateIntentForCollection builds an intent for the given database and collection name
// along with a path to a .bson collection file. It searches the file's parent directory
// for a matching metadata file.
//
// This method is not called by CreateIntentsForDB,
// it is only used in the case where --db and --collection flags are set.
func (restore *MongoRestore) CreateIntentForCollection(db string, collection string, dir archive.DirLike) error {
	log.Logvf(log.DebugLow, "reading collection %v for database %v from %v",
		collection, db, dir.Path())
	// first make sure the bson file exists and is valid
	_, err := dir.Stat()
	if err != nil {
		return err
	}
	if dir.IsDir() {
		return fmt.Errorf("file %v is a directory, not a bson file", dir.Path())
	}

	baseName, fileType := restore.getInfoFromFilename(dir.Name())
	if fileType != BSONFileType {
		return fmt.Errorf("file %v does not have .bson extension", dir.Path())
	}

	// then create its intent
	intent := &intents.Intent{
		DB:       db,
		C:        collection,
		Size:     dir.Size(),
		Location: dir.Path(),
	}
	intent.BSONFile = &realBSONFile{path: dir.Path(), intent: intent, gzip: restore.InputOptions.Gzip}

	// finally, check if it has a .metadata.json file in its folder
	log.Logvf(log.DebugLow, "scanning directory %v for metadata", dir.Name())
	entries, err := dir.Parent().ReadDir()
	if err != nil {
		// try and carry on if we can
		log.Logvf(log.Info, "error attempting to locate metadata for file: %v", err)
		log.Logv(log.Info, "restoring collection without metadata")
		restore.manager.Put(intent)
		return nil
	}
	metadataName := baseName + ".metadata.json"
	if restore.InputOptions.Gzip {
		metadataName += ".gz"
	}
	for _, entry := range entries {
		if entry.Name() == metadataName {
			metadataPath := entry.Path()
			log.Logvf(log.Info, "found metadata for collection at %v", metadataPath)
			intent.MetadataLocation = metadataPath
			intent.MetadataFile = &realMetadataFile{path: metadataPath, intent: intent, gzip: restore.InputOptions.Gzip}
			break

	restore.manager.Put(intent)

	return nil
