Socket#connect_nonblock working?

[ioquatix]

I print out the status from

  def connect_nonblock(sockaddr, exception: true)
    fcntl(Fcntl::F_SETFL, Fcntl::O_NONBLOCK)

    if sockaddr.is_a?(Addrinfo)
      sockaddr = sockaddr.to_sockaddr
    end

    status = Truffle::Socket::Foreign.connect(descriptor, sockaddr)

    if status < 0
      if exception
        Truffle::Socket::Error.write_nonblock('connect(2)')
      else
        :wait_writable
      end
    else
      0
    end
  end

and it's always -1.

The exact same code works fine on MRI.

What's odd is that the server accepts the connection but it continues to return -1:

Server accepting...
Client connect...
status=-1
Server read...
status=-1
status=-1
status=-1
status=-1
status=-1
status=-1

Okay so I found out the problem. You are not correctly handling Errno::EISCONN.

Fixed by #1465.
