在所有错误情况下，我需要采取什么措施来进行故障转储? [英] What actions do I need to take to get a crash dump in ALL error scenarios?

问题描述

我们在Windows上，我们希望针对应用程序意外退出的 all 方案进行故障转储(可能使用 MiniDumpWriteDump ).

We're on Windows and we want to get a crash dump (possibly using MiniDumpWriteDump) for all scenarios where our application exit's unexpectedly.

到目前为止，我们已经确定并设置了以下内容:

So far we have identified, and set up, the following:

• SetUnhandledExceptionFilter 用于未处理的异常(Win32以及常规" C ++异常.)
• _set_invalid_parameter_handler 用于CRT无效参数处理
• _set_abort_behavior 加上一个 SIGABRT 处理程序，以解决对 abort()
的调用

• SetUnhandledExceptionFilter for unhandled exception (Win32 as well as "normal" C++ ones.)
• _set_invalid_parameter_handler for the CRT invalid argument handling
• _set_abort_behaviorplus a SIGABRT handler to account for calls to abort()

有什么我们想念的吗?(对某些代码进行非法模块化，非法调用 ExitProcess ， TerminateProcess 或 exit 变体之一.)

Is there anything we missed? (Modulo some code non-legitimately calling ExitProcess, TerminateProcess or one of the exit variants.)

我会注意到，这里的问题与如何崩溃崩溃转储正交.例如，如果您要在发生 abort 的情况下进行崩溃转储，则必须始终使用 _set_abort_behaviour ，因为否则将中止 exit s.

I'll note that this question here is orthogonal to how a crash dump is then obtained. E.g., if you want a crash dump in case of abort, you always must use _set_abort_behaviour because otherwise abort just exits.

我还将注意到，在Windows7 +上，不是设置 SetUHEF 并仅设置通常是可行的方法.

I'll also note that on Windows7+, not setting SetUHEF and just setting up the "correct" WER dump settings in the registry is often a viable way.

推荐答案

我完全使用您列出的内容，加上 _set_purecall_handler ，以及以下方便的代码段:

I use exactly the ones you've listed, plus _set_purecall_handler, plus this handy snippet of code:

void EnableCrashingOnCrashes()
{
    typedef BOOL (WINAPI *tGetPolicy)(LPDWORD lpFlags);
    typedef BOOL (WINAPI *tSetPolicy)(DWORD dwFlags);
    static const DWORD EXCEPTION_SWALLOWING = 0x1;

    const HMODULE kernel32 = LoadLibraryA("kernel32.dll");
    const tGetPolicy pGetPolicy = (tGetPolicy)GetProcAddress(kernel32, "GetProcessUserModeExceptionPolicy");
    const tSetPolicy pSetPolicy = (tSetPolicy)GetProcAddress(kernel32, "SetProcessUserModeExceptionPolicy");
    if(pGetPolicy && pSetPolicy)
    {
        DWORD dwFlags;
        if(pGetPolicy(&dwFlags))
        {
            // Turn off the filter
            pSetPolicy(dwFlags & ~EXCEPTION_SWALLOWING);
        }
    }
}
