運行 Go 程序時與垃圾收集器相關的恐慌

Question

我從 GitHub 安裝了一個 Go 程序，當我運行它時，出現錯誤，

panic: Something in this program imports go4.org/unsafe/assume-no-moving-gc to declare that it assumes a non-moving garbage collector, but your version of go4.org/unsafe/assume-no-moving-gc hasn't been updated to assert that it's safe against the go1.18 runtime. If you want to risk it, run with environment variable ASSUME_NO_MOVING_GC_UNSAFE_RISK_IT_WITH=go1.18 set. Notably, if go1.18 adds a moving garbage collector, this program is unsafe to use.

似乎沒有太多與此相關的信息。 我在 Go 的編碼經驗為零。

任何幫助深表感謝。 我很樂意提供您可能需要的任何額外信息。

PS：我安裝的程序是 metabignor，它是用go install github.com/j3ssie/metabigor@latest 。

Answer 1

您也可以使用go get -u go4.org/unsafe/assume-no-moving-gc升級assume-no-moving-gc來解決這個問題。

Answer 2

恐慌錯誤是由您導入的庫觸發的。

https://github.com/go4org/unsafe-assume-no-moving-gc/blob/main/untested.go

func init() {
    dots := strings.SplitN(runtime.Version(), ".", 3)
    v := runtime.Version()
    if len(dots) >= 2 {
        v = dots[0] + "." + dots[1]
    }
    if os.Getenv(env) == v {
        return
    }
    panic("Something in this program imports go4.org/unsafe/assume-no-moving-gc to declare that it assumes a non-moving garbage collector, but your version of go4.org/unsafe/assume-no-moving-gc hasn't been updated to assert that it's safe against the " + v + " runtime. If you want to risk it, run with environment variable " + env + "=" + v + " set. Notably, if " + v + " adds a moving garbage collector, this program is unsafe to use.")
}

如錯誤所述，您需要設置此環境變量

ASSUME_NO_MOVING_GC_UNSAFE_RISK_IT_WITH=go1.18

或者，將 go 運行時升級到 go1.19
