不能使用单声道软调试器远程调试，因为“调试程序代理：DWP握手失败”错误 [英] Can't use Mono Soft Debugger Remote Debugging because 'debugger-agent: DWP handshake failed' error

问题描述

我在我的应用程序嵌入单。该应用程序是一个支持插件控制台应用程序。插件是.NET程序集。所有工作的伟大，但我想他们调试。要启用调试在我的C code，我有：

I've embedded mono in my application. The application is console application that supports plug-ins. Plug-ins are .NET assemblies. All work great, but i want to debug them. To enable debugging in my C-code i have:

mono_set_dirs (ASSEMBLIES_DIR_NAME, ASSEMBLIES_DIR_NAME);
assembly_add_to_bundle(API_ASSEMBLY);

soft_debug = getenv("MYAPP_SOFT_DEBUG");
if (soft_debug != NULL) {
   char *options; 
   options = malloc(17 + strlen(soft_debug));
   sprintf(options, "--debugger-agent=%s", soft_debug); 

   mono_jit_parse_options (1, &options); 
   free (options); 

   mono_debug_init (MONO_DEBUG_FORMAT_MONO);
}

domain = JIT_INIT();

...

在code以上inits单声道运行时，这就是我对我所做的启用调试。 要启用调试在MonoDevelop的身边，我已经创建了一个加载项并实施必要的类。而其中，开始调试从RemoteSoftDebuggerSession来源。这是我的OnRun方式：

The code above inits mono runtime and it's all i've done to enable debugging. To enable debugging at MonoDevelop side i've created an Add-in and implemented necessary classes. The one that starts debugging is derived from RemoteSoftDebuggerSession. Here is my OnRun method:

protected override void OnRun (DebuggerStartInfo startInfo)
{
   var dsi = (MyAppDebuggerStartInfo) startInfo;
   var procStartInfo = new ProcessStartInfo(@"C:\MyApp\myapp.exe") {                
    UseShellExecute = false,
    RedirectStandardOutput = true,
    RedirectStandardError = true,
    WorkingDirectory = @"C:\MyApp",
    Arguments = dsi.AppName
   };

   procStartInfo.EnvironmentVariables.Add("MYAPP_SOFT_DEBUG",                       
      String.Format("transport=dt_socket,address={0}:{1}", 
         dsi.Address, dsi.DebugPort));

   this._myapp = Process.Start(procStartInfo);
   this._runner.EnableRaisingEvents = true;
   base.ConnectOutput(this._runner.StandardOutput, false);
   base.ConnectOutput(this._runner.StandardError, true);

   this._runner.Exited += delegate { this.EndSession(); };
   base.StartListening(dsi);
}

现在的问题是，当我开始调试的myapp打印调试代理：DWP握手失败和调试结束。 所有我能想出的是，正好13个字节发送到MYAPP.EXE和13字节：收到。

The problem is when i start debugging myapp prints "debugger-agent: DWP handshake failed" and debugging ends. All i could figure out is that exactly 13 bytes are sent to myapp.exe and 13 bytes are recieved (the number of chars in "DWP-Handshake").

推荐答案

问题就解决了​​。麻烦的是VirtualMachineManager.ListenInternal（2）在该行方式：

Problem is solved. The trouble was in VirtualMachineManager.ListenInternal(2) method in this lines:

dbg_sock.Disconnect (false);
dbg_sock.Close ();

出于某种原因，这是未处理的异常（上断开）在这里。的try-catch解决了这个问题。现在，所有的伟大工程！

For some reason it was unhandled exception (on Disconnect) here. try-catch solved the problem. Now all works great!
