6 ao_sleep crash - ID: 1550365

Last Update: Comment added ( jplauril )

Details:

Hi,
this crashes pys60 1.3.1 on N70 when joystick is
pressed sufficiently fast:

import appuifw, e32
appuifw.app.body=appuifw.Listbox([u'press joystick'],
lambda: e32.ao_sleep(100))
lock=e32.Ao_lock()
appuifw.app.exit_key_handler=lock.signal
lock.wait()
appuifw.app.exit_key_handler=None

I don't know if this is the same bug that I stumbled on
when using bluetooth or not: #1540691 (Crash using BT
socket and keypad)

Date: 2007-06-12 19:00 Sender: jplauril Same problem with active scheduler nesting as in http://sourceforge.net/tracker/index.php?func=detail&aid=1550413&group_id=154155&atid=790646 Fix: Don't have long-running callbacks.
Date: 2006-10-11 12:42 Sender: vbartoni Logged In: YES user_id=1178755 Correction. It's not needed to press fast, crash causes 19th press on joystick's ok at N70 with 1.3.1 pyS60. Same behaviour at 1.3.11 sdk. N80 needs about 40-ish presses.

Date: 2006-10-05 06:37 Sender: otsov Logged In: YES user_id=1371303 This is a known "feature" with "e32.ao_sleep()". There is an active scheduler loop ongoing and you are most probably exiting before this loop is finished. This results in stray signal and hence panic. This "feature" should have been solved by using "e32.Ao_timer" which can be cancelled if there is a pending call. Unfortunaly "e32.Ao_timer" contains also a bug at the time of writing (search the Forum Nokia Discussion Board for a temporary solution). See also API doc on "e32.Ao_timer" type. "e32.Ao_timer" will be fixed - no fix will be available for "e32.ao_sleep" - a programmer needs to be sure that there is not an ongoing sleep prior exiting. This should be documented also to "e32.ao_sleep" API description.
