Hi,

how can I kill a thread that does not respond anymore?

I start the the thread like this:

thread.start_new_thread(bt_scan,())

Here's quite a thread about thread: http://discussion.forum.nokia.com/fo...d.php?t=118547
What do you mean by "does not respond"?

Ok, I call the finddevices() function from the lightblue module to do a bluetooth scan. Normaly this function delivers after 10-30 sec a list with all found BT devices, but sometimes it does not deliver anything, it just hangs and the thread cannot close automatically.

I thought to ta start the finddevices function in the second thread and wait at least 120 sec and then close the first thread and I thought that with closing the first thread, the second thread would also close but it doesn't. os.getpid() deliverers the same id for each thread, so it could not be killed. How can I kill or abort the hanging thread?

def bt_mainthread():
	global bt_busy
	thread.start_new_thread(bt_scan,())
	time.sleep(1)
	while bt_busy and (bt_scan_time < 120):
		time.sleep(1)
	if bt_scan_time > 119:
		blues.off()
		time.sleep(5)
		blues.on()
		time.sleep(5)
		bt_busy = False
		
def bt_scan():
	global btscan, btquery_list, bt_busy, bt_scan_time
	bt_busy = True
	bt_scan_time = 0
	try:
		btscan = lightblue.finddevices()
	except:
		btscan = []
	btquery_list = []
	for i in range(len(btscan)):
		btquery_list.append(query_bt(btscan[i]))
	bt_busy = False

def loop():
   global bt_busy, bt_scan_time
   if config['BT_SCAN'] > 0 and not bt_busy:
	bti += 1
	if (bti > config['BT_SCAN']*1) and not bt_busy:
	   bti = 0
	   thread.start_new_thread(bt_mainthread,())

			
   if bt_busy:
	bt_block += 1
	bt_scan_time += 1

Did you come up with a solution to this?

PyS60 does not have a function for this. But looks like it's possible on Symbian:

So native extension is needed.

Hello,

I have problems killing a thread in python. The whole app. seems to crash.
I tried this:

import thread

def subthread():
    global bla1, bla2, bla3
    while subthread_active:
        # do something

# start the subthread
subthread_active = True
thread.start_new_thread(subthread, ())

# stop the subthread
subthread_active = False

As a result of "subthread_active = False" the whole application is chrashing.

[miohtama]

def subthread():
    global bla1, bla2, bla3
    while subthread_active:
        # do something

# start the subthread
subthread_active = True
thread.start_new_thread(subthread, ())

# stop the subthread
subthread_active = False

You need to give CPU time to the main thread or the application is stuck in the subthread. Call e32.ao_sleep() or similar in the worker loop. Also, subthread_active must be a global variable.
