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.
