Golang Backups Examples

Example #1

File: backup.go Project: bac/juju

func (h *backupHandler) upload(backups backups.Backups, resp http.ResponseWriter, req *http.Request) (string, error) {
	// Since we want to stream the archive in we cannot simply use
	// mime/multipart directly.
	defer req.Body.Close()

	var metaResult params.BackupsMetadataResult
	archive, err := httpattachment.Get(req, &metaResult)
	if err != nil {
		return "", err
	}

	if err := validateBackupMetadataResult(metaResult); err != nil {
		return "", err
	}

	meta := apiserverbackups.MetadataFromResult(metaResult)
	id, err := backups.Add(archive, meta)
	if err != nil {
		return "", err
	}

	if err := sendStatusAndJSON(resp, http.StatusOK, &params.BackupsUploadResult{ID: id}); err != nil {
		return "", errors.Trace(err)
	}
	return id, nil
}

Example #2

File: backup.go Project: bac/juju

func (h *backupHandler) download(backups backups.Backups, resp http.ResponseWriter, req *http.Request) (string, error) {
	args, err := h.parseGETArgs(req)
	if err != nil {
		return "", err
	}
	logger.Infof("backups download request for %q", args.ID)

	meta, archive, err := backups.Get(args.ID)
	if err != nil {
		return "", err
	}
	defer archive.Close()

	err = h.sendFile(archive, meta.Checksum(), resp)
	return args.ID, err
}
