pkg/schema/filewriter.go:265–272

writeFileMap uploads chunks of r to bs while populating fileMap and finally uploading fileMap. The returned blobref is of fileMap's JSON blob. It uses rolling checksum for the chunks sizes.

(ctx context.Context, bs blobserver.StatReceiver, file *Builder, r io.Reader)
