在新的jenkins项目中配置git repo时出现此错误:

Failed to connect to repository : Error performing command:  ls-remote -h file:///c:\Dev\git\rx HEAD

我在我的Windows机器上有一个本地git repo,并且从同一台机器上的命令提示符克隆相同的路径.我不知道可能是什么问题(git.exe在系统路径上)

我在.NET进程中进行了转储(使用-ma选项和procdump.exe中高CPU的触发器),我希望在运行的线程中看到关于我的代码正在做什么的线索.我明白了:

*** procdump  -ma -c 65 -s 2 -n 3 service.exe
*** Process exceeded 65% CPU for 2 seconds. Thread consuming CPU: 4396 (0x112c)'

指示的线程在转储时执行:

我有这段代码,想要了解:

template <unsigned...>
struct sum;

template<unsigned size>
struct sum<size>
{
    enum {value = size};
};

template<unsigned size, unsigned... sizes>
struct sum<size, sizes...>
{
    enum { value = size + sum<sizes...>::value }; 
};

int _tmain(int argc, _TCHAR* argv[])
{
    sum<1, 2>::value;
    return 0;
}

我不明白为什么未实现的和(取无符号......就像最后一个结构专门化,是不是存在冲突？)必须存在,以及如何使用模板部分中的相同参数来专门化和(e.g. sum<size, sizes...>如同template <unsigned size, sizes...>为什么波纹管不起作用？

template<unsigned size>
struct sum
{
    enum {value = size};
};

template<unsigned size, unsigned... sizes>
struct sum
{
    enum { value = size + sum<sizes...>::value; }; 
};
