Current code:
#!/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()
}
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.
It's not expected behaviour and this problem is already reported. The workaround for this is using posix_spawn
instead of Process
.
