(original) (raw)

Hello,

Can someone explain me why gc(CPython) can not collect recursive closure's cycle reference? There is no \_\_del\_\_ here, why gc can not collect?

Thanks a lot.

For example:

#!/usr/bin/env python

import ipdb

import gc

gc.set\_debug(gc.DEBUG\_LEAK)

def A():

N = \[1\]

def aa(n):

if n in N:

return 1

else:

return n \* aa(n-1)

x = 33 + aa(10)

#ipdb.set\_trace()

print x

if \_\_name\_\_ == '\_\_main\_\_':

while xrange(1000):

A()

Best
