the c function test3() is called, which calls test2(), which calls test1(). In test1(), there is a NULL pointer assignment, which will cause segmentation fault. To get the core dump, "ulimit -c unlimited" and "echo "core" > /proc/sys/kernel/core_pattern" are run. The code is ...

4.6 #35: Using defer inside a loop(在loop循环中使用defer语句) 在每个for循环的迭代作用域中调用defer是不会在迭代结束的时候执行,只有最内层函数调用返回的时候才会执行defer,如果每次迭代都打开了一个文件描述符,想要及时关闭: 每次迭代之后就主动关闭,不借助于defer的能力 放在一个函数闭包内,当闭包执行完之后...

In this tutorial, we will demonstrate how the CPU time is spent quantitatively inside Go’s CockroachDB withOpenResty XRay. We will show the most CPU-intensive Go code paths in it.OpenResty XRaywill automatically analyze and interpret the Go (golang) language level CPU flame graph. ...
