Swift macOS Process.run()端口泄漏 [英] Swift macOS Process.run() port leak

问题描述

当前代码:

#!/usr/bin/swift

import Foundation

func runSleepProcess() {
    let sleepProcess = Process()
    sleepProcess.executableURL = URL(fileURLWithPath: "/bin/sleep")
    sleepProcess.arguments = ["0"]
    try? sleepProcess.run()
    sleepProcess.waitUntilExit()
}

while true {
    runSleepProcess()
}

在活动监视器中，似乎马赫端口的使用在每个循环中增加了1.运行外部进程时，这是预期的行为吗?如果没有，如何解决泄漏?谢谢.

Looking in activity monitor, it seems that the mach port usage increases by 1 each loop. Is this expected behavior when running an external process? If not, how do I fix the leak? Thanks.

推荐答案

这不是预期的行为，并且已经报告了此问题.解决方法是使用posix_spawn代替Process.

It's not expected behaviour and this problem is already reported. The workaround for this is using posix_spawn instead of Process.
