Subject [jira] Created: (ETCH-80) Windows 7 / .NET 3.5 SP1 runtime setsockopt error

Windows 7 / .NET 3.5 SP1 runtime setsockopt error
-------------------------------------------------

                 Key: ETCH-80
                 URL: https://issues.apache.org/jira/browse/ETCH-80
             Project: Etch
          Issue Type: Bug
          Components: csharp-binding
    Affects Versions: 1.0.2
         Environment: Windows 7, Visual Studio 2008 SP1
            Reporter: James E. King, III
            Priority: Critical


When starting a client or server in this environment an exception is thrown and the socket
closes with the following stack - this stops everything:

System.Net.Sockets.SocketException: An unknown, invalid, or unsupported option or level was
specified in a getsockopt or setsockopt call
      at System.Net.Sockets.Socket.SetSocketOption(SocketOptionLevel optionLevel, SocketOptionName
optionName, Int32 optionValue, Boolean silent)
      at System.Net.Sockets.Socket.SetSocketOption(SocketOptionLevel optionLevel, SocketOptionName
optionName, Int32 optionValue)
      at Etch.Util.TcpTransport.SetUpSocket() in c:\BambooAgent\xml-data\build-dir\ETCH-RELEASE\binding-csharp\runtime\src\main\csharp\Etch\Util\TcpTransport.cs:line
193
      at Etch.Util.Connection`1.Run0(Boolean first) in c:\BambooAgent\xml-data\build-dir\ETCH-RELEASE\binding-csharp\runtime\src\main\csharp\Etch\Util\Connection.cs:line
116

Fix:

In TcpTransport, a call is made to SetSocketOption with SocketOptionLevel.Tcp set.  The correct
SocketOptionLevel is .Socket, and this will fix the issue.  By setting it to .Tcp, the socket
sends a SO_BROADCAST which is invalid for TCP.
