XmlRpcSerializer.DeserializeResponse() #90

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?

 I'm calling Server.Login()
 DeserializeResponse() is called with a MemoryStream
 AllowInvalidHTTPContent is false
 when the using XmlTextReader statement ends it is disposed
 this has the side affect of calling stm.Close()
 this stream was created by XmlRpcClientProtocol.Invoke()
 and it expects it to remain usable
 Line "deserStream.Position = 0;" generates the exception
 System.ObjectDisposedException

What is the expected output? What do you see instead?

 no exception

What version of the product are you using? On what operating system?

 Version 2.5.0 Release
 Windows XP

Please use labels and text to provide additional information.

  I can prevent the exception by moving this block from inside the if(AllowInvalidHTTPContent) to just before it so that it always copies

     // Never dispose the original input stream
     Stream newStm = new MemoryStream();
     Util.CopyStream(stm, newStm);
     stm = newStm;
     stm.Position = 0;

  I am compiling C# with VS 8 and .NET 3.5
