Fixes #3713

server.go Outdated
if e := t.WriteStatus(stream, st); e != nil {
channelz.Warningf(logger, s.channelzID, "grpc: Server.processUnaryRPC failed to write status %v", e)
}
st, _ := status.FromError(err)

Let's use toRPCErr instead for this conversion.

Oh no.. maybe not. That doesn't guarantee a status is returned. It can return io.EOF. It is nicer than status.FromError in that it handles other types of errors, though.

OK, this is good enough, then, since we don't expect it to not be a status in most cases. But please use status.Convert instead and remove the st variable.
