Creating tickets in Trac with XmlRpc and C# .NET

Programmatically creating tickets in a Trac system using the recommended approach of XmlRpc is actually fairly straight-forward. The documentation and various sources were confusing to me at first, so I thought I would document the steps I went through to set it up. For me, I had a basic Trac instance on Windows set up, with the AccountManagerPlugin enabled.

Go here: http://trac-hacks.org/wiki/XmlRpcPlugin.
From the command-line, run the easy_install option that suits you, I ran easy_install -Z -U http://trac-hacks.org/svn/xmlrpcplugin/trunk
As per the link above, enable the plugin in trac.ini, and if you’re using the AccountManagerPlugin, make sure you follow the instructions.
Fire up Trac - you should now have the XmlRpcPlugin running in Trac.
Go to the Admin section in Trac, and to Permissions. You will need to add the XML_RPC permission to the user account that requires it - in my case I added it to my own login for testing purposes:
If you browse to your Trac instance /rpc (e.g. http://localhost:8000/rpc) you will see the full XmlRpc API, with all possible methods to implement.
Create a new Visual Studio project, and implement the methods you want. I just implemented two methods, CreateTicket and AddAttachment as follows (according to the example shown here):

public struct TicketAttributes
{
}

[XmlRpcUrl("http://localhost:8000/login/xmlrpc")]
public interface TracXmlRpcProxy : IXmlRpcProxy
{

    [XmlRpcMethod("ticket.create")]
    int CreateTicket(string summary, string description, TicketAttributes attributes, bool notify, DateTime when);

    [XmlRpcMethod("ticket.putAttachment")]
    string AddAttachment(int ticketId, string filename, string description, byte[] data, bool replace = true);
}

class Program
{
    static void Main(string[] args)
    {
        TracXmlRpcProxy proxy;

        // Fill these in appropriately
        string user = "matt";
        string password = "password!";

        /// Create an instance of the Trac interface
        proxy = XmlRpcProxyGen.Create();

        // If desired, point this to your URL. If you do not do this,
        // it will use the one specified in the service declaration.
        // proxy.Url = "https://trac-rules.org/xmlrpc";

        // Attach your credentials
        proxy.Credentials = new System.Net.NetworkCredential(user, password);

        TicketAttributes attr;
        //attr.comment = "This is the comment that goes with the new page";
        int ticketId = proxy.CreateTicket("Xml Rpc Test", "This is an XML RPC Test", attr, false, DateTime.Now);

        byte[] fileData = File.ReadAllBytes("C:\Temp\test.jpg");
        proxy.KeepAlive = false;
        proxy.AddAttachment(ticketId, "test.jpg", "Test description", fileData, true);

        Console.WriteLine("Ticket ID: " + ticketId);
    }
}

One thing to note with the above is the proxy.KeepAlive = false: this HAS to be set before sending the attachment otherwise you get the following error: “The server committed a protocol violation. Section=ResponseStatusLine”.
