[google] 使用breakpad生成dump文件

什么是Google Breakpad？

Google Breakpad is a cross platform crash handler which generates minidumps when your application crash. Users can send these minidumps to you and it contains valuable information allowing you to figure out why it crashed on them.

获取源码：

git clone https://chromium.googlesource.com/breakpad/breakpad

安装python

这里面略过了，但是记住要使用Python2.x,，Python3.x会报错

什么是gyp

GYP（Generate Your Projects）是由 Chromium 团队开发的跨平台自动化项目构建工具，Chromium 便是通过 GYP 进行项目构建管理。

https://chromium.googlesource.com/external/gyp

git clone https://chromium.googlesource.com/external/gyp

安装gyp

cd gyp
python setup.py install

拷贝gyp文件夹到breakpad\src\tools文件夹下

使用gyp生成breakpad的sln工程文件

E:\git\breakpad\src\tools\gyp>set GYP_MSVS_VERSION=2015
E:\git\breakpad\src\tools\gyp>gyp.bat --no-circular-check "../../client/windows/breakpad_client.gyp"
Warning: Missing input files:
..\..\client\windows\unittests\..\..\..\testing\googlemock\src\gmock-all.cc
..\..\client\windows\unittests\..\..\..\testing\googletest\src\gtest-all.cc
..\..\client\windows\unittests\..\..\..\testing\googletest\src\gtest_main.cc

然后会在目录E:\git\breakpad\src\client\windows下生成breakpad_client.sln工程。

测试工程

#include <stdio.h>
#include "client/windows/handler/exception_handler.h"

using namespace google_breakpad;

    const wchar_t* dump_path,
    const wchar_t* minidump_id,
    void* context,

    MDRawAssertionInfo* assertion,
    bool succeeded)
{
    if (succeeded)
    {
        printf("dump guid is %ws\n", minidump_id);
    }
    else
    {
        printf("dump failed\n");
    }
    fflush(stdout);
    return succeeded;
}

void errFun(int * p)
{
    *p = 1;
}

int main()
{
    google_breakpad::ExceptionHandler oExceptionHandler(
        L".",
        NULL,
        s_bMinidumpCallback,
        NULL,
        google_breakpad::ExceptionHandler::HANDLER_ALL
    );

    int * p = NULL;
    errFun(p);
    return 0;
}
