[Python-Dev] Unexpected increase of globals() refcount

[Chandra Srinivasan]

Hi,
I ran the following code in the Python interpreter and am trying to determine if the behavior I see is expected:

import sys
print sys.getrefcount(globals())
class Foo(object):
   def __init__(self):
      pass
print sys.getrefcount(globals())

The first print statement above prints '4' and the second one prints '5'. However, if I remove the __init__ method from the class, the refcount stays the same.

If I change the above code like this, the ref count stays the same:

import gc
import sys
print sys.getrefcount(globals())
class Foo(object):
   def __init__(self):
      pass
del Foo
while gc.collect():
  pass
print sys.getrefcount(globals())

Can you let me know if this is a bug in the Python interpreter?
