如何在Windows 7中打开GCStress？ [英] How to turn GCStress on in Windows 7?

问题描述

我正在调试 GC 堆腐败，并进入了我的步骤想尝试在WinDbg + PageHeap + AppVerifier + GCStress下运行程序。

I am debugging a GC heap corruption and came to the step where I want to try running the program under WinDbg + PageHeap + AppVerifier + GCStress.

我在文章中找到了 软件崩溃：故障模块mscorwks.dll，版本1.1.4322.2379 我可以这样启用GCStress：

I found in the article Software crash: faulting module mscorwks.dll, version 1.1.4322.2379 that I can enable GCStress like this:

reg.exe add "HKLM\SOFTWARE\Microsoft\.NETFramework" /f  /v HeapVerify  /t REG_DWORD  /d 1  
reg.exe add "HKLM\SOFTWARE\Microsoft\.NETFramework" /f  /v StressLog  /t REG_DWORD  /d 1  
reg.exe add "HKLM\SOFTWARE\Microsoft\.NETFramework" /f  /v GCStress  /t REG_DWORD  /d 3  
reg.exe add "HKLM\SOFTWARE\Microsoft\.NETFramework" /f  /v FastGcStress  /t REG_DWORD  /d 2

（我正在尝试这种方法。它需要程序永远启动。我从注册表中删除了最后两个条目以使其正常工作，这可能是方法本身有问题。）

(I am trying this method. It takes the program forever to launch. I deleted the last two entries from the registry to have it work, probably something is wrong with the approach itself.)

或者文章访问冲突在.NET 4运行时gc_heap :: garbage_collect中没有非管理模块 描述了另一种方法：

Or the article Access Violation in .NET 4 Runtime in gc_heap::garbage_collect with no unmanaged modules described the other method:

(DWORD) StressLog = 1  
(DWORD) LogFacility = 0xffffffff  
(DWORD) StressLogSize = 65536

哪种方式是正确的或是另一个正确的方式

Which way is correct or is there another correct way?

推荐答案

我在Koders上搜索GCStress 。原来，通过查看 .NET的源代码：

enum  GCStressFlags {
    GCSTRESS_NONE               = 0,
    GCSTRESS_ALLOC              = 1,    // GC on all allocations and 'easy' places
    GCSTRESS_TRANSITION         = 2,    // GC on transitions to preemtive GC
    GCSTRESS_INSTR_JIT          = 4,    // GC on every allowable JITed instruction
    GCSTRESS_INSTR_NGEN         = 8,    // GC on every allowable NGEN instruction
    GCSTRESS_UNIQUE             = 16,   // GC only on a unique stack trace
};
