I'm creating a script to monitor my mouse/keyboard activity. The intent is to update a timestamp whenever I move the mouse or press a button the keyboard. I've threaded the mouse and keyboard check methods and the main thread will check if we have passed the timeout/inactive duration and click at a specified location if we have.
Unfortunately, the keyboard monitoring is not working. The pynput.keyboard.Listener object seems to never join().
I'm not particularly comfortable with multithreading but I think I need it for this script. Please share a better way if there is one. I want to be able to run this script/class as a thread in another script later.
from pynput.keyboard import Listener
import pyautogui as gui
import threading, time
from datetime import datetime, timedelta
class activity(threading.Thread):
def __init__(self, timeout: int = 60):
self.stop_flag = False
self.timeout = timedelta(seconds=timeout)
self.last_timestamp = datetime.now()
def update_timestamp(self):
self.last_timestamp = datetime.now()
print('timestamp updated')
# For monitoring if the keyboard is active
def keybd_monitoring(self, lock: threading.Lock) -> None:
with Listener(on_release=lambda x: True) as listener:
listener.join()
lock.acquire()
self.update_timestamp()
lock.release()
print('Keyboard pressed')
if self.stop_flag:
return
# For monitoring if the mouse is active
def mouse_monitoring(self, lock: threading.Lock) -> None:
last_position = gui.position()
while not self.stop_flag:
time.sleep(3)
curr_position = gui.position()
if last_position != curr_position:
last_position = curr_position
lock.acquire()
self.update_timestamp()
lock.release()
print('Mouse Moved')
def stop(self):
self.stop_flag = True
# For monitoring if the mouse/keyboard have been used in the last TIMEOUT seconds
def run(self):
try:
width, height = gui.size()
lock = threading.Lock()
mouse = threading.Thread(target=self.mouse_monitoring, args=(lock,))
keybd = threading.Thread(target=self.keybd_monitoring, args=(lock,))
mouse.start()
keybd.start()
while not self.stop_flag:
time.sleep(.1)
if datetime.now() > self.last_timestamp + self.timeout:
curr_position = gui.position()
gui.click(int(width*.6),height)
gui.moveTo(curr_position)
finally:
self.stop()
if mouse.is_alive():
mouse.join()
if keybd.is_alive():
keybd.join()
if __name__ == '__main__':
act = activity()
act.run()
I've made it work without the monitoring functions being in a class. I'm still curious if it could work within a class.

You should use a classmethod instead of a staticmethod for joinQ.
You also had a rdyq (bar.py last line) instead of the expected rdyQ and Python is case-sensitive.

Python variables and attributes are case sensitive, so "rdyq" is not the same as "rdyQ".
You set the name with a capital q, so maybe this will fix it?
Factory.rdyQ.put(i)
I recommend using_underscores_for_variables as you avoid issues camelCase can cause.
I have a python tool, that has basically this kind of setup:
main process (P1) -> spawns a process (P2) that starts a tcp connection
-> spawns a thread (T1) that starts a loop to receive
messages that are sent from P2 to P1 via a Queue (Q1)
server process (P2) -> spawns two threads (T2 and T3) that start loops to
receive messages that are sent from P1 to P2 via Queues (Q2 and Q3)
The problem I'm having is that when I stop my program (with Ctrl+C), it doesn't quit. The server process is ended, but the main process just hangs there and I have to kill it.
The thread loop functions all look the same:
def _loop(self):
while self.running:
res = self.Q1.get()
if res is None:
break
self._handle_msg(res)
All threads are started as daemon:
t = Thread(target=self._loop)
t.setDaemon(True)
t.start()
In my main process, I use atexit, to perform clean-up tasks:
atexit.register(self.on_exit)
Those clean-up tasks are essentially the following:
1) set self.running in P1 to False and sent None to Q1, so that the Thread T1 should finish
self.running = False
self.Q1.put(None)
2) send a message to P2 via Q2 to inform this process that it is ending
self.Q2.put("stop")
3) In P2, react to the "stop" message and do what we did in P1
self.running = False
self.Q2.put(None)
self.Q3.put(None)
That is it and in my understanding, that should make everything shut down nicely, but it doesn't.
The main code of P1 also contains the following endless loop, because otherwise the program would end prematurely:
while running:
sleep(1)
Maybe that has something to do with the problem, but I cannot see why it should.
So what did I do wrong? Does my setup have major design flaws? Did I forget to shut down something?
EDIT
Ok, I modified my code and managed to make it shut down correctly most of the time. Unfortunately, from now and then, it still got stuck.
I managed to write a small working example of my code. To demonstrate what happens, you need to simple start the script and then use Ctrl + C to stop it. It looks like the issue appears now usually if you press Ctrl + C as soon as possible after starting the tool.

I think you're corrupting your multiprocessing.Queue by calling p.terminate() on on the child process. The docs have a warning about this:
Warning: If this method is used when the associated process is using a
pipe or queue then the pipe or queue is liable to become corrupted and
may become unusable by other process. Similarly, if the process has
acquired a lock or semaphore etc. then terminating it is liable to
cause other processes to deadlock.
In some cases, it looks like p is terminating before your MediatorSender._loop method can consume the sentinel you loaded into it to let it know that it should exit.
Also, you're installing a signal handler that expects to work in the main process only, but the SIGINT is actually received by both the parent and the child processes, which means signal_handler gets called in both processes, could result in ms.stop getting called twice, due to a race condition in the way you handle setting ms.running to False
I would recommend just exploiting that both processes receive the SIGINT, and have both the parent and child handle KeyboardInterrupt directly. That way, each then have each shut themselves down cleanly, rather than have the parent terminate the child. The following code demonstrates that, and in my testing never hung. I've simplified your code in a few places, but functionally it's exactly the same:

If you prefer to use a signal handler rather than catching KeyboardInterrupt, you just need to make sure the child process uses its own signal handler, rather than inheriting the parent's:

Maybe you should try to capture SIGINT signal, which is generated by Ctrl + C using signal.signal like this:
#!/usr/bin/env python
import signal
import sys
def signal_handler(signal, frame):
print('You pressed Ctrl+C!')
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
print('Press Ctrl+C')
signal.pause()

This usually works for me if I am using the threading module. It will not work if you use the multiprocessing one though. If you are running the script from the terminal try running it in the background, like this.
python scriptFoo.py &
After you run the process it will output the PID like this
[1] 23107
Whenever you need to quit the script you just type kill and the script PID like this.
kill 23107
Hit enter again and it should kill all the subprocesses and output this.
[1]+ Terminated python scriptFoo.py
As far as I know you cannot kill all the subprocesses with 'Ctrl+C'
I have an interactive console program in windows. I need to press keystroke like 'e' 'c' to the cmd window. It's convenient for human operating , but very difficult for program automation.
And now, I would like to wrap the console program, in order to make it more easy to be manipulated in other program like python.
However, the console program uses 'getch()' to get keyboard input , which is not standard input. So, I can't simply send key into stdin.
Did anyone ever come across this problem?
Thanks.

As far as I know, getch() does use standard input. COuld it be that the application did receive that input, but you don't receive its output? That's a common problem, as output often gets buffered if it is not directed at a terminal. Can you adjust the program to flush its output after each line?
I see a number of problems with your python code: you don't create a pipe for stderr, and the proc variable appears to be local to the start method.
You might want to leave the subprocess output inherited from the python process for the time being. That should suppress buffering and rules out any errors in the ThreadWorker as well.
All you need to do is:
Write a file with each step in a new line:
for instance:
step 1
step 2
step 3
then call the program like this:
program.exe < input.txt

I was looking for some example of python xlib global keybinding that would work with gtk3, just as it is done for gtk2 at http://www.siafoo.net/snippet/239. Very similar code here:
from Xlib.display import Display
from Xlib import X

import gobject
class GlobalKeyBinding (gobject.GObject, threading.Thread):
__gsignals__ = {
'activate': (gobject.SIGNAL_RUN_LAST, gobject.TYPE_NONE, ()),
}
def __init__ (self):
gobject.GObject.__init__ (self)
threading.Thread.__init__ (self)
self.setDaemon (True)
self.keymap = gtk.gdk.keymap_get_default ()
self.display = Display ()
self.screen = self.display.screen ()
self.root = self.screen.root

gtk.gdk.MOD3_MASK, gtk.gdk.MOD4_MASK, gtk.gdk.MOD5_MASK,
gtk.gdk.SUPER_MASK, gtk.gdk.HYPER_MASK)
self.known_modifiers_mask = 0
for modifier in gdk_modifiers:
self.known_modifiers_mask |= modifier
def add_grab_key(self,accelerator,signal):
if not accelerator:
return
keyval,modifiers=gtk.accelerator_parse(accelerator)
if not keyval or not modifiers:
return
keycode=self.keymap.get_entries_for_keyval(keyval)[0][0]
self.keybindings[signal]=[accelerator,
keycode,
int (modifiers)]
#grab_key operation forces X to exclusivelly send given keycode (like apostrophe char) to current X client (unless other X client grabbed it before).
#`X.AnyModifier' parameter tells to register the keycode for all modifiers, thus Ctrl-', Alt-', Shift-', ' will all be sent to this X client.
# given keyval is grabbed by current X client until `ungrab_key' is called.
return self.root.grab_key (keycode, X.AnyModifier, True, X.GrabModeAsync, X.GrabModeSync)

Unfortunately I didn't find one, thus I decided to reimplement it to use gtk3 (ubuntu 12.04). Below is the result. It does not have runtime errors, but unfortunatelly it does not grab any input.

Maybe You have some ideas how to make it work?
best regards,

Hey i implemented same code and working great, you can try this. but there is no warranty. If you find missing parts please tell me.
