Various socket spec failures
----------------------------

                 Key: JRUBY-2039
                 URL: http://jira.codehaus.org/browse/JRUBY-2039
             Project: JRuby
          Issue Type: Bug
          Components: Core Classes/Modules
    Affects Versions: JRuby 1.1RC1
            Reporter: Ola Bini
            Assignee: Ola Bini


There are nine different failures in specs for sockets, that can't be 
attributed to bad specs (some specs reference AF_UNIX without guarding against 
it, which is wrong).

The nine failures I have in mind are condensed in this file:

{noformat}

require 'socket'

describe "Socket#unpack_sockaddr_in" do
  it "decodes the host name and port number of a packed sockaddr_in" do
    sockaddr = Socket.sockaddr_in 80, '127.0.0.1'
    Socket.unpack_sockaddr_in(sockaddr).should == [80, '127.0.0.1']
  end

  it "raises an ArgumentError when the sin_family is not AF_INET" do
    sockaddr = Socket.sockaddr_un '/tmp/x'

    lambda { Socket.unpack_sockaddr_in sockaddr }.should 
raise_error(ArgumentError)
  end
end

describe "Server class hierarchy" do
  it "contains UNIXServer" do
    UNIXServer.superclass.should == UNIXSocket
  end
end

describe "The socket class hierarchy" do
  it "has a UNIXSocket in parallel to Socket" do
    Socket.ancestors.include?(UNIXSocket).should == false
    UNIXSocket.ancestors.include?(Socket).should == false
    UNIXSocket.superclass.should == BasicSocket
  end
end

describe "Socket#getservbyname" do
  it "identifies service ports " do
    Socket.getservbyname('http').should == 80
    Socket.getservbyname('http', 'tcp').should == 80
    Socket.getservbyname('http', 'udp').should == 80
    Socket.getservbyname('daytime').should == 13
  end

  it "raises a SocketError when the service or port is invalid" do
    lambda { Socket.getservbyname('invalid') }.should raise_error(SocketError)
  end
end


describe "BasicSocket#setsockopt" do
  before(:each) do
    @sock = Socket.new(Socket::AF_INET, Socket::SOCK_STREAM, 0)
  end
  
  it "sets the socket linger to 0" do
    linger = [0, 0].pack("ii")
    @sock.setsockopt(Socket::SOL_SOCKET, Socket::SO_LINGER, linger).should == 0
  end
end

describe "BasicSocket#getsockopt" do
  before(:each) do
    @sock = Socket.new(Socket::AF_INET, Socket::SOCK_STREAM, 0)
  end
  
  it "gets a socket option" do
    n = @sock.getsockopt(Socket::SOL_SOCKET, Socket::SO_TYPE)
    n.should == [Socket::SOCK_STREAM].pack("i")
  end

  it "raises a SystemCallError with an invalid socket option" do
    lambda { @sock.getsockopt Socket::SOL_SOCKET, -1 }.should \
      raise_error(Errno::ENOPROTOOPT)
  end
end
