使用回调调用MiniDumpWriteDump

Question

我想使用MiniDumpWriteDump函数来创建一些自定义转储文件(主要是,我想导出包含线程调用堆栈的最少信息量的转储文件),但是我很难定义需要传递的结构回调函数的参数

[StructLayout(LayoutKind.Explicit)]
internal struct MINIDUMP_CALLBACK_OUTPUT
{
    [FieldOffset(0)]
    public ulong ModuleWriteFlags;
    [FieldOffset(0)]
    public ulong ThreadWriteFlags;
}

public struct MINIDUMP_CALLBACK_INFORMATION
    {
        public IntPtr CallbackRoutine;
        public IntPtr CallbackParam;
    }

public delegate bool MINIDUMP_CALLBACK_ROUTINE(
        IntPtr CallBackParam, 
        MINIDUMP_CALLBACK_INPUT input, 
        MINIDUMP_CALLBACK_OUTPUT output);

[DllImport("dbghelp.dll")]
public static extern bool MiniDumpWriteDump(IntPtr hProcess, Int32 ProcessId, IntPtr hFile, int DumpType,
    IntPtr ExceptionParam, IntPtr UserStreamParam, IntPtr CallStackParam);

电话看起来像这样:

MINIDUMP_CALLBACK_INFORMATION mci;
MINIDUMP_CALLBACK_ROUTINE r = new MINIDUMP_CALLBACK_ROUTINE(MyCallback);
GC.KeepAlive(r);
mci.CallbackRoutine = Marshal.GetFunctionPointerForDelegate(r);
mci.CallbackParam = IntPtr.Zero;    
IntPtr structPointer = Marshal.AllocHGlobal(Marshal.SizeOf(mci));    
Marshal.StructureToPtr(mci, structPointer, true);    
MiniDumpWriteDump(process[0].Handle, process[0].Id,
                        fs.SafeFileHandle.DangerousGetHandle(),
                        (int)MINIDUMP_TYPE.MiniDumpNormal,
                        Marshal.GetExceptionPointers(),
                        IntPtr.Zero,
                        structPointer);

Marshal.FreeHGlobal(structPointer);

所以我的问题是如何定义MINIDUMP_CALLBACK_INPUT:

C中存在问题的结构的定义是:

typedef struct _MINIDUMP_CALLBACK_INPUT 
{
    ULONG                       ProcessId;
    HANDLE                      ProcessHandle;
    ULONG                       CallbackType;
    union 
    {
        MINIDUMP_THREAD_CALLBACK        Thread;
        MINIDUMP_THREAD_EX_CALLBACK     ThreadEx;
        MINIDUMP_MODULE_CALLBACK        Module;
        MINIDUMP_INCLUDE_THREAD_CALLBACK IncludeThread;
        MINIDUMP_INCLUDE_MODULE_CALLBACK IncludeModule;
    } u;
} MINIDUMP_CALLBACK_INPUT

typedef struct _MINIDUMP_MODULE_CALLBACK 
{
    PWCHAR                      FullPath;
    ULONGLONG                   BaseOfImage;
    ULONG                       SizeOfImage;
    ULONG                       CheckSum;
    ULONG                       TimeDateStamp;
    VS_FIXEDFILEINFO            VersionInfo;
    PVOID                       CvRecord;
    ULONG                       SizeOfCvRecord;
    PVOID                       MiscRecord;
    ULONG                       SizeOfMiscRecord;
} MINIDUMP_MODULE_CALLBACK

这不是您问题的直接答案，而是一种解决方法......

您知道ClrDump库可以满足您的需要吗？几年前我在一个项目中使用过它，它对我来说效果很好。

在网站上阅读：

ClrDump 可以生成小型小型转储，其中包含足够的信息来恢复应用程序中所有线程的调用堆栈。

我将 API 封装在以下类中：

internal class ClrDump
{
  [return: MarshalAs(UnmanagedType.Bool)]
  [DllImport("clrdump.dll", CharSet=CharSet.Unicode, SetLastError=true)]
  public static extern bool CreateDump(uint ProcessId, string FileName, MINIDUMP_TYPE DumpType, uint ExcThreadId, IntPtr ExtPtrs);

  [return: MarshalAs(UnmanagedType.Bool)]
  [DllImport("clrdump.dll", CharSet=CharSet.Unicode, SetLastError=true)]
  public static extern bool RegisterFilter(string FileName, MINIDUMP_TYPE DumpType);

  [DllImport("clrdump.dll")]
  public static extern FILTER_OPTIONS SetFilterOptions(FILTER_OPTIONS Options);

  [return: MarshalAs(UnmanagedType.Bool)]
  [DllImport("clrdump.dll", SetLastError=true)]
  public static extern bool UnregisterFilter();


  [Flags]
  public enum FILTER_OPTIONS
  {
    CLRDMP_OPT_CALLDEFAULTHANDLER = 1
  }

  [Flags]
  public enum MINIDUMP_TYPE
  {
    MiniDumpFilterMemory = 8,
    MiniDumpFilterModulePaths = 0x80,
    MiniDumpNormal = 0,
    MiniDumpScanMemory = 0x10,
    MiniDumpWithCodeSegs = 0x2000,
    MiniDumpWithDataSegs = 1,
    MiniDumpWithFullMemory = 2,
    MiniDumpWithFullMemoryInfo = 0x800,
    MiniDumpWithHandleData = 4,
    MiniDumpWithIndirectlyReferencedMemory = 0x40,
    MiniDumpWithoutManagedState = 0x4000,
    MiniDumpWithoutOptionalData = 0x400,
    MiniDumpWithPrivateReadWriteMemory = 0x200,
    MiniDumpWithProcessThreadData = 0x100,
    MiniDumpWithThreadInfo = 0x1000,
    MiniDumpWithUnloadedModules = 0x20
  }
}

然后，在初始化代码中的某个位置，我调用了 RegisterFilter 方法，该方法为当前进程中未处理的异常注册一个内部过滤器。如果进程因未处理的异常（可以是本机异常或托管异常）而崩溃，过滤器将捕获它并创建一个小型转储（具有指定的文件名）。这是一个示例代码：

StringBuilder sb = new StringBuilder();
sb.Append(Path.GetFileNameWithoutExtension(Application.ExecutablePath));
sb.Append("_");
sb.Append(DateTime.Now.ToString("yyyyMMddHHmmssFF"));
sb.Append(".dmp");
string dmpFilePath = Path.Combine(Path.GetTempPath(), sb.ToString());
ClrDump.RegisterFilter(_dmpFilePath, ClrDump.MINIDUMP_TYPE.MiniDumpNormal);

您可以阅读本文来了解不同的 MINIDUMP_TYPE 选项，但我认为基本选项 (MiniDumpNormal) 可以满足您的需求。
