Method SetModTime

backend/hasher/object.go:150–155

SetModTime sets the modification time of the file. Also prunes the cache entry when modtime changes so that touching a file will trigger checksum recalculation even on backends that don't provide modTime with fingerprint.

(ctx context.Context, mtime time.Time)

// touching a file will trigger checksum recalculation even
// on backends that don't provide modTime with fingerprint.
func (o *Object) SetModTime(ctx context.Context, mtime time.Time) error {
	if mtime != o.Object.ModTime(ctx) {
		_ = o.f.pruneHash(o.Remote())
	}
	return o.Object.SetModTime(ctx, mtime)
}

// Open opens the file for read.
// Full reads will also update object hashes.
