运行Go程序时与垃圾收集器相关的恐慌

Question

我从GitHub安装了一个Go程序，当我运行它时，我得到了错误，

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.

似乎与此相关的信息并不多。我对围棋没有编码经验。

任何帮助都是非常感谢的。我很乐意提供你可能需要的任何额外信息。

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

Answer 1

您还可以通过使用assume-no-moving-gc来解决这个问题来升级go get -u go4.org/unsafe/assume-no-moving-gc。

Answer 2

您导入的库会触发恐慌错误。

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.")
}

正如错误所说的，您需要设置这个env var。

ASSUME_NO_MOVING_GC_UNSAFE_RISK_IT_WITH=go1.18

或者，将go运行时升级到go1.19
