[Release] C7/Co2 AutoPatch Server Emulator

[Y u k i]

Crystal Seven AutoPatch Server

Image from the today´s stress test, connected in a infinite loop to it, checking the ressurce usage and for fails. Nothing happened in 20min :3

We moved away from the official TQ AutoPatch.exe so we have no use for this anymore. I thought, since it works perfectly fine (Distributed our first 5 Patches during 2 Weeks without restart / crash / leak across a load of players, I should release it for you guys. Its nothing fancy, I didnt even implement a own socket system - I´ve written it in around two hours because the ACME-EO one didnt run on our vps. More information below! Have fun!

• TQ´s Patch Protocol - Works with the official AutoPatch.exe
• Very little ressource usage
• From our observations: Stable
• Readable Code

How does it work?

Please... figure it out. I dont feel like explaining the obvious, i even let my data there so you can check for yourselfe.

PHP Code:

class ConnectionThread
    {
        private TcpListener Client;
        const string SERVERVERSION = "http://79.133.51.70/crystalseven/version.txt";
        const string UPDATE = "UPDATE";
        byte[] READY = { 52, 45, 41, 44, 59 };
        const string HOST = "79.133.51.70";
        const string PATH = "crystalseven/downloads/patches/";
        const char JUNK = (char)0x0000;
        static WebClient Web = new WebClient();

        public ConnectionThread(TcpListener client)
        {
            Client = client;
        }

        public void HandleConnection()
        {
            byte[] buffer;
            try
            {
                using (TcpClient client = Client.AcceptTcpClient())
                {
                    using (NetworkStream ns = client.GetStream())
                    {
                        Console.WriteLine("{0}  -  Connection", DateTime.Now);

                        buffer = new byte[1024];
                        ns.Read(buffer, 0, buffer.Length);
                        int ClientVersion = int.Parse(Encoding.ASCII.GetString(buffer).Substring(0, 4).Trim(JUNK));
                        int ServerVersion = int.Parse(Web.DownloadString(SERVERVERSION));

                        if (ServerVersion == ClientVersion)
                        {
                            Console.WriteLine("{0} || Client @ {1} Version: {2} ==> READY", DateTime.Now, ((IPEndPoint)client.Client.RemoteEndPoint).Address.ToString(), ClientVersion);
                            client.Client.Send(Encoding.ASCII.GetBytes("READY"));
                        }
                        else if (ServerVersion > ClientVersion)
                        {
                            Console.WriteLine("{0} || Client @ {1} Version: {2} ==> UPDATE", DateTime.Now, ((IPEndPoint)client.Client.RemoteEndPoint).Address.ToString(), ClientVersion);
                            ClientVersion++;
                            client.Client.Send(Encoding.ASCII.GetBytes(UPDATE + " " + HOST + " " + PATH + ClientVersion + ".exe"));
                        }
                    }

                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
            }
        }
    } 


There is no config file! Everything is hardcoded! You might wanna change the values!

Nice job dom, valuable release.

Ooooooo, Thanks I had no idea on how to do it xD

I don't know wether you had issues with the download process using the WebClient class. Recently I had to use it and after some googling I found that by doing

WebClient.Proxy = null;

, it speeds up the download a lot.

Further releases will be here. Epvp is already one version behind.

You can now fully configure it in a config.ini file instead of recompiling it
