How to kill a thread?

[John Dohn]

Hi there,

How can I kill a threading.Thread subclass from MainThread?

My threads are waiting for data in Queue.get() method:
class MyThread(threading.Thread):
def run(self):
while True:
data = queue.get()# <- here it waits most of the time
... process data

>From the main thread I start several working threads:
thr = MyThread()
thr.start()
... feed the queue
and at the end for each thread I'd like to do something like thr.kill() or
thr.stop() or thr.destroy() or ... you got the point. I can't figure out
how.

Is there a way to do it?

Thanks!

At the end I did:

def run(self):
while True:
if exit_event.isSet():
# Thread exiting
return
try:
data = q_in.get(timeout = .5)
except Queue.Empty:
continue
# ... process data

And then in the MainThread I do exit_event.set() and wait for all threads to
exit. It's a pretty awkward solution but works.

BTW Guys, is something like Thread.kill() planned for the future? Or is
there a reason not to have it?

Thanks

You'll need some AJAX progress bar (hint: google for this term ;-) that will
be getting updates from the server or request an update every second or so.

The question is if your upload code can provide progress tracking? If it's
just a call to some xyz.upload("/here/is/my-500M-file.bin") that only
returns after several minutes of uploading without giving you any updates on
how fast things go you're probably out of luck.
OTOH if it can do e.g.callbacks for progress reporting or if it can run in a
separate thread that you could query somehow you can hook that to that AJAX
thing of your choice.
