Message1650

sys.settrace cannot be changed. In the pydev debugger, I'd like to give users a warning if they're trying to change sys.settrace while running the debugger, so, I was trying to change it after setting up the debugger to give a warning (and only then call the original function), but this doesn't seem to work.

The code below shows what's happening:

original = sys.settrace
sys.settrace = lambda *args,**kwargs:None
print '%s should differ %s' % (original, sys.settrace)

Is there some other way to change it under jython? (I've tried changing sys.__dict__['settrace'], but the final result is the same)
