Hello all,
I am currently using cython for a project related to openmoko cell
phone : http://charlie137-2.blogspot.com/2008/07/introducing-tichy.html
I noticed that the memory is constantly increasing when I use cython. I
tracked down the problem to the case where I create a subclass of a
cython class and then redefine a cpdef method, asking it to call the
parent method, but ONLY if the cpdef method then call an other cpdef
method !
Here is the smallest example I could come with that fails :
== test.pyx ==
cdef class A:
cpdef func(self):
return
cpdef test(self):
self.func()
== main.py ==
import test
import gc
class B(test.A):
def test(self):
test.A.test(self)
b = B()
for i in range(10):
b.test()
gc.collect()
print len(gc.get_objects())
The output will show that some objects are not released.
Is it a known bug ? Is there a way to avoid it ?
