Python线程名称未显示在ps或htop上

Question

当我为Python线程设置名称时，它不会显示在htop或ps上。ps输出仅显示python为线程名称。有什么方法可以设置线程名称，使其显示在类似它们的系统报告上？

from threading import Thread
import time


def sleeper():
    while True:
        time.sleep(10)
        print "sleeping"

t = Thread(target=sleeper, name="Sleeper01")
t.start()
t.join()

ps -T -p {PID}输出

  PID  SPID TTY          TIME CMD
31420 31420 pts/30   00:00:00 python
31420 31421 pts/30   00:00:00 python

Answer 1

首先安装prctl模块。（在debian /
ubuntu上只需输入sudo apt-get install python-prctl）

from threading import Thread
import time
import prctl

def sleeper():
    prctl.set_name("sleeping tiger")
    while True:
        time.sleep(10)
        print "sleeping"

t = Thread(target=sleeper, name="Sleeper01")
t.start()
t.join()

此打印

$ ps -T
  PID  SPID TTY          TIME CMD
22684 22684 pts/29   00:00:00 bash
23302 23302 pts/29   00:00:00 python
23302 23303 pts/29   00:00:00 sleeping tiger
23304 23304 pts/29   00:00:00 ps
