[issue9524] CTRL_C_EVENT and CTRL_BREAK_EVENT cannot be registered by signal.signal() method on windows

2010-08-05 Thread Valentine Gogichashvili 

New submission from Valentine Gogichashvili :

When executing the following code on Windows 7 64-bit ::

  import sys
  import signal
  import time
  print 'Version:'
  print sys.executable or sys.platform, sys.version
  print
  print

  def h(s, f): print s

  signal.signal(signal.CTRL_BREAK_EVENT, h)

we get the following output::

  Version:
  C:\Python27\python.exe 2.7 (r27:82525, Jul  4 2010, 07:43:08) [MSC   
v.1500 64 bit (AMD64)]

  Traceback (most recent call last):
  File "signal_ctrl_break_event.py", line 14, in 
signal.signal(signal.CTRL_BREAK_EVENT, h)
  RuntimeError: (0, 'Error')

When trying to register a handler for a signal.CTRL_C_EVENT the exception is as 
follows::

  File "signal_ctrl_c_event.py", line 6, in 
signal.signal(signal.CTRL_C_EVENT, h)
  ValueError: signal number out of range

[issue9534] OrderedDict.__del__ destructor throws AttributeError when process ends up with the exception trace

2010-08-06 Thread Valentine Gogichashvili 

New submission from Valentine Gogichashvili :

When the process is dying with the exception trace dump, I am getting the 
following notification from the destructor of the OrderedDict class::

  Exception AttributeError: "'NoneType' object has no attribute 'print_exc'" in 
 ignored

In the source of the OrderedDict the only operation that is not included in the 
try..catch is the dict.clear(self) actually. So I suppose that this problem is 
in dict.clear() implementation...

Valentine Gogichashvili  added the comment:

Unfortunately I do not have a short script. It is happening during the failure 
in quite a big script. I am afraid, it will too time consuming for me to write 
it... 

Actually by the content of the OrderdDict instance that is throwing this 
exception it seems like it is the one, that is used by ConfigParser internally.
