Just to be sure I answer your question fully:
case 1) the original 0.9.1 ipython code gives this error if I start it
with -gthread and push ctrl-c
##########################
CODE (in Shell.py, around linenr. 840):
update_tk(self.tk)
self.IP.runcode()
time.sleep(0.01)
return True
ERROR:
KeyboardInterrupt - Press <Enter> to
continue.---------------------------------------------------------------------------
IOError Traceback (most recent call last)
c:\python25\lib\site-packages\IPython\Shell.pyc in on_timer(self)
840 update_tk(self.tk)
841 self.IP.runcode()
--> 842 time.sleep(0.01)
843 return True
844
IOError: [Errno 4] Interrupted function call
#################
case 2) catching the exception (with some prints):
###############
CODE:
try:
update_tk(self.tk)
self.IP.runcode()
time.sleep(0.01)
return True
except Exception, e:
print type(e)
print(e)
return True
ERROR:
KeyboardInterrupt - Press <Enter> to continue. <type 'exceptions.IOError'>
[Errno 4] Interrupted function call
#########################
case 3) if I understood correctly this is what you wanted to see:
#####################
CODE:
update_tk(self.tk)
self.IP.runcode()
try:
time.sleep(0.01)
return True
except Exception ,e:
print type(e)
print e
return True
ERROR:
KeyboardInterrupt - Press <Enter> to continue. <type 'exceptions.IOError'>
[Errno 4] Interrupted function call
##########################
case 3a) occasionally (1 in ~20 times), if you interrupt the code while
it is not in the sleep, then everything works fine. It gives this message:
############################
CODE: (same as case 3, and probably the same for 1 and 2)
ERROR:
KeyboardInterrupt - Press <Enter> to continue.
###########################
I hope this answers your question. If you want me to check any more
things, please ask.
