+Summary: Socet.Select on Write
+
+After update to 1.1.8 (Win32) version Socket.Select does not working on
+Select Write Mode properly
+After Accepted connecion
+Socket.Select(ConnectionListRead, ConnectionListWrite, null, 100);
+
+ConnectionListRead has two socket availabe for read
+ConnectionListWrite has no socket ready for write
+?
+no problem with older version of runtime and core lib
+
+----------------------------- CODE --------------------------------
+using System;
+using System.Collections;
+using System.Net;
+using System.Net.Sockets;
+using System.Threading;
+
+class SocketTest
+{
+
+ public static int Main()
+ {
+ IPEndPoint ipEndpoint = new IPEndPoint(IPAddress.Any, 80);
+ Socket ListeningSocket = new Socket(ipEndpoint.AddressFamily,
+SocketType.Stream, ProtocolType.Tcp);
+
+ ListeningSocket.Blocking = false;
+ ListeningSocket.Bind (ipEndpoint);
+ ListeningSocket.Listen(1000);
+
+
+ // Pooling
+
+ ArrayList AcceptedClientList = new ArrayList();
+
+ while(true)
+ {
+ Socket Client = null;
+
+ if ( ListeningSocket.Poll(0, SelectMode.SelectRead) )
+ {
+ try
+ {
+ Client = ListeningSocket.Accept ();
+ Client.Blocking = false;
+
+ Console.WriteLine(&quot;Accpet Connection from: &quot; +
+Client.RemoteEndPoint.ToString());
+ AcceptedClientList.Add(Client);
+
+
+ }
+ catch(Exception ex)
+ {
+ Console.WriteLine(&quot;Excpetion: &quot; + ex.Message);
+ }
+
+ }
+
+ if(AcceptedClientList.Count == 0) continue;
+
+ ArrayList ConnectionListRead = new ArrayList(AcceptedClientList);
+ ArrayList ConnectionListWrite = new ArrayList(AcceptedClientList);
+
+ Socket.Select(ConnectionListRead, ConnectionListWrite, null, 100);
+
+ int i = 0;
+
+ foreach ( Socket sock in ConnectionListRead )
+ {
+ Console.WriteLine(&quot;Can Read: &quot; + sock.RemoteEndPoint.ToString() + &quot; i=&quot;
++ i++);
+ }
+
+ i = 0;
+ foreach ( Socket sock in ConnectionListWrite )
+ {
+ Console.WriteLine(&quot;Can Write: &quot; + sock.RemoteEndPoint.ToString() + &quot; i=&quot;
++ i++);
+ }
+
+
+ break;
+
+ }
+
+ return 0;
+ }
+}
+--------------------------- END CODE -------------------------------------
+
+Actual Results:
+Accpet Connection from: 127.0.0.1:1225
+Can Read: 127.0.0.1:1225 i=0
+Can Read: 127.0.0.1:1225 i=1
+
+Expected Results:
+Accpet Connection from: 127.0.0.1:1224
+Can Read: 127.0.0.1:1224 i=0
+Can Write: 127.0.0.1:1224 i=0
+
+
+How often does this happen?
+1.1.8 Windows Version not tested on Unix/Linux Platform
