I have verified that Inline::Python also does not handle cyclic garbage
collection:
===== test.pl =====
use strict;
use warnings;
use Inline::Python;
Inline::Python::eval_python("import destructor_test");
my $obj = Inline::Python::py_call_function("destructor_test", "get_object");
my $other = Inline::Python::py_call_function("destructor_test",
"get_object", $obj);
Inline::Python::py_call_method($obj, "attach", $other);
===== destructor_test.py =====
def get_object(other=None):
c = Class()
c.attach(other)
return c
class Class(object):
def __del__(self):
print "Destructor"
def attach(self, other):
self.other = other
==============================
Running test.pl prints no output, therefore the python destructor is not
getting called. If I remove the calls to "attach", both are deleted
correctly.
