如何:使用WinDBG的调试死锁



WinDbg / SOS小抄




CLRStack [-a] [-l] [-p] [-n]提供
A堆栈只托管代码痕迹。




  • -p选项显示的参数给
    管理功能。


  • -l选项显示在一个框架
    局部变量的信息。该SOS
    调试扩展无法检索
    本地名称,所以输出为当地
    名称格式为
    =。


  • -a(全部)选项是
    -l和-pcombined。

  • $ B $快捷方式b
  • -n选项禁用
    源文件名和行号的显示。如果
    中的调试器选项$指定b $ B SYMOPT_LOAD_LINES,SOS将
    查找符号每个托管
    帧,如果成功会显示
    相应的源文件名和
    线号。该-n(没有行号)
    参数可以被指定为禁止
    这种行为。




该SOS调试扩展没有在x64和
基于IA-64平台不
显示的过渡帧。

更新:(感谢@Liran):要查看所有线程调用堆栈在你的应用程序,运行以下命令:

 〜* E!clrstack 

(这基本上意味着遍历所有的线程,并执行他们每个人)命令!clrstack。


When I issued clrstack command, I got the following output. It is the callstack of a blocking thread which owns a deadlock and results in a deadlock. Is that its exact purpose? Does it have any other purposes (without any parameters). Where can I get more information?

!clrstack

How to: Debug Deadlocks Using Windbg?

WinDbg / SOS Cheat Sheet

CLRStack [-a] [-l] [-p] [-n] Provides a stack trace of managed code only.

  • The -p option shows arguments to the managed function.

  • The -l option shows information on local variables in a frame. The SOS Debugging Extension cannot retrieve local names, so the output for local names is in the format = .

  • The -a(all) option is a shortcut for -l and -pcombined.

  • The -n option disables the display of source file names and line numbers. If the debugger has the option SYMOPT_LOAD_LINES specified, SOS will look up the symbols for every managed frame and if successful will display the corresponding source file name and line number. The -n (No line numbers) parameter can be specified to disable this behavior.

The SOS Debugging Extension does not display transition frames on x64 and IA-64-based platforms.

Update: (Thanks to @Liran): To see the call stacks for all the threads in your application, run the following command:

 ~*e!clrstack 

(which basically means, "iterate over all of the threads, and execute the command '!clrstack' on every one of them").
