SuperSocket中的Server的初始化和启动

一、初始化的过程

static void Main(string[] args)
{
  var bootstrap = BootstrapFactory.CreateBootstrap();

            if (!bootstrap.Initialize())
            {
                Console.WriteLine("Failed to initialize!");
                Console.ReadKey();
                return;
            }
}

supersocket\socketengine\defaultbootstrap.cs

DefaultBootStrap.cs
  public virtual bool Initialize()
        {
            return Initialize(c => c);
        }

  public virtual bool Initialize(Func<IServerConfig, IServerConfig> serverConfigResolver)
        {
            return Initialize(serverConfigResolver, null);
        }

 public virtual bool Initialize(Func<IServerConfig, IServerConfig> serverConfigResolver, ILogFactory logFactory)
{
   foreach (var factoryInfo in workItemFactories)
            {
                IWorkItem appServer = InitializeAndSetupWorkItem(factoryInfo);
            }
}

private IWorkItem InitializeAndSetupWorkItem(WorkItemFactoryInfo factoryInfo)
        {
   setupResult = SetupWorkItemInstance(appServer, factoryInfo);

}

internal virtual bool SetupWorkItemInstance(IWorkItem workItem, WorkItemFactoryInfo factoryInfo)
{
return workItem.Setup(this, factoryInfo.Config, factoryInfo.ProviderFactories.ToArray());
}

supersocket\socketbase\appserverbase.cs

 bool IWorkItem.Setup(IBootstrap bootstrap, IServerConfig config, ProviderFactoryInfo[] factories)
{
     Bootstrap = bootstrap;
if (!SetupFinal())
                return false;

} 

private bool SetupFinal()
{
  return SetupSocketServer();
}

  private bool SetupSocketServer()
{
   m_SocketServer = m_SocketServerFactory.CreateSocketServer<TRequestInfo>(this, m_Listeners, Config);
}

supersocket\socketengine\socketserverfactory.cs

 public ISocketServer CreateSocketServer<TRequestInfo>(IAppServer appServer, ListenerInfo[] listeners, IServerConfig config)
            where TRequestInfo : IRequestInfo
{
 case(SocketMode.Tcp):
                    return new AsyncSocketServer(appServer, listeners);
}

二、启动的过程

 var bootstrap = BootstrapFactory.CreateBootstrap();
 var result = bootstrap.Start();

supersocket\socketengine\defaultbootstrap.cs

//Initialize servers
foreach (var factoryInfo in workItemFactories)
{
IWorkItem appServer = InitializeAndSetupWorkItem(factoryInfo);

if (appServer == null)
return false;

if (factoryInfo.IsServerManager)
serverManager = appServer;
else if (!(appServer is IsolationAppServer))//No isolation
{
//In isolation mode, cannot check whether is server manager in the factory info loader
if (TypeValidator.IsServerManagerType(appServer.GetType()))
serverManager = appServer;
}

m_AppServers.Add(appServer);
}

public StartResult Start()
{
    foreach (var server in m_AppServers)
    {
        if (!server.Start())
                {}
     }
}

supersocket\socketbase\appserver.cs

   public override bool Start()
{
   if (!base.Start())
                return false;
}

supersocket\socketbase\appserverbase.cs

m_SocketServer = m_SocketServerFactory.CreateSocketServer<TRequestInfo>(this, m_Listeners, Config);

   public virtual bool Start()
{
if (!m_SocketServer.Start())
            {
                m_StateCode = ServerStateConst.NotStarted;
                return false;
            }
}
 

SuperSocket\SocketEngine\AsyncSocketServer.cs

public override bool Start()
{
if (!base.Start())
                    return false;
}    

supersocket\socketengine\socketserverbase.cs

var listener = CreateListener(ListenerInfos[i]);

d:\sourcecode\github\supersocket\socketengine\tcpsocketserverbase.cs

protected override ISocketListener CreateListener(ListenerInfo listenerInfo)
{
return new TcpAsyncSocketListener(listenerInfo);
}

d:\sourcecode\github\supersocket\socketengine\tcpasyncsocketlistener.cs

public TcpAsyncSocketListener(ListenerInfo info)
: base(info)
{
m_ListenBackLog = info.BackLog;
}

d:\sourcecode\github\supersocket\socketengine\socketlistenerbase.cs

protected SocketListenerBase(ListenerInfo info)
{
Info = info;
}

public SocketServerBase(IAppServer appServer, ListenerInfo[] listeners)
{
AppServer = appServer;
IsRunning = false;
ListenerInfos = listeners;
Listeners = new List<ISocketListener>(listeners.Length);
}

public TcpSocketServerBase(IAppServer appServer, ListenerInfo[] listeners)
: base(appServer, listeners)

public virtual bool Start()
{
 if (listener.Start(AppServer.Config))
    {
     }
}
 

SuperSocket\SocketEngine\TcpAsyncSocketListener.cs

d:\sourcecode\github\supersocket\socketengine\socketlistenerbase.cs

public ListenerInfo Info { get; private set; }

protected SocketListenerBase(ListenerInfo info)
{
Info = info;
}

  public override bool Start(IServerConfig config)
{
 m_ListenSocket = new Socket(this.Info.EndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
if (!m_ListenSocket.AcceptAsync(acceptEventArg))
                    ProcessAccept(acceptEventArg);
}
