ADB Python-Daemon子进程没有连接

Question

我有一个简单的python守护进程，它将在执行我的主要测试时在后台运行。这段代码在我的Ubuntu盒上运行得很好，但是由于在我的Mac上试用了它，所以我无法让它工作。

    #! /usr/bin/env python

import daemon
import time as t
import subprocess


def logging():
    while True:
        n = str(10)
        m = str(1)
        i = t.time()
        cpu = open("filepath/to/file" + str(i) + ".txt", "w")
        ram = open("filepath/to/file" + str(i) + ".txt", "w")
        disk = open("filepath/to/file", "a")
        subprocess.call(['adb', 'shell', 'top', '-m', n, '-n', m], stdout=cpu, stderr=cpu)
        subprocess.call(['adb', 'shell', 'cat /proc/meminfo'], stdout=ram)
        subprocess.call(['adb', 'shell', 'df', '/data'], stdout=disk)


def run():
    with daemon.DaemonContext():
        logging()


if __name__ == "__main__":
    run()

每当我执行这段代码时，stderr就会给出以下输出：

* daemon not running; starting now at tcp:5037
ADB server didn't ACK

我能够连接到我的设备与亚行和运行我的主要测试。这个守护进程似乎不想在Mac上与亚行合作。

30.0.1-6435776

任何帮助都是非常感谢的！

我找到了一项利用线程而不是守护进程的工作。有关代码，请参阅下面。

import subprocess
import os
from threading import Thread
from datetime import datetime


def run():
    while True:
        m = str(1)
        now = datetime.now().strftime('%Y-%m-%d %H:%M:%S.%f')
        cpu = open("/path/to/file" + str(now) + ".txt", "w")
        ram = open("/path/to/file" + str(now) + ".txt", "w")
        disk = open("/path/to/file/DISK.txt", "a")
        subprocess.call(['adb', 'shell', 'top', '-n', m], stdout=cpu, stderr=cpu)
        subprocess.call(['adb', 'shell', 'cat /proc/meminfo'], stdout=ram)
        subprocess.call(['adb', 'shell', 'df', '/data'], stdout=disk)


def run2():
    subprocess.call(['pytest', 'file.py', '-v', '-s'])
    os._exit(1)


if __name__ == "__main__":
    t1 = Thread(target=run)
    t2 = Thread(target=run2)
    t1.setDaemon(True)
    t2.setDaemon(True)
    t1.start()
    t2.start()
    while True:
        pass

此线程使用多线程在后台运行“后台”进程(run)，而主pytest进程运行(run2)。然后，当pytest进程结束时，我使用os._exit(1)来终止后台进程(运行)。
