golang 结构体内部变量被引用实验

结论

struct 的某个 filed 被引用的时候 struct 本身就不会被垃圾回收器回收。

操作步骤

$ go run memtest.go -cpuprofile cpu.pprof -memprofile mem.pprof

goimports_fix() {
    hash goimports 2>&- || { echo >&2 "goimports not in PATH."; exit 1; }

    for file in `git diff --cached --name-only --diff-filter=d | grep -v vendor | grep '\.go$'`
    do
        if [[ ! -z `git diff --name-only ${file} | grep '\.go$'` ]]
