[issue15293] AST nodes do not support garbage collection

2014-05-24 Thread Benjamin Peterson 

Benjamin Peterson added the comment:

How are you reproducing the bug? In Python 2, the AST base class doesn't have a 
__dict__, and it's subtypes do support GC.

[issue15293] AST nodes do not support garbage collection

2014-05-22 Thread Charles-François Natali 

Charles-François Natali added the comment:

Would it be possible to backport this to 2.7?
We've been bitten by this at work (pyflakes introduces reference cycles in AST).

2012-07-08 Thread Antoine Pitrou 

New submission from Antoine Pitrou pit...@free.fr:

Add the following to test_ast:

diff --git a/Lib/test/test_ast.py b/Lib/test/test_ast.py
--- a/Lib/test/test_ast.py
+++ b/Lib/test/test_ast.py
@@ -199,6 +199,7 @@ class AST_Tests(unittest.TestCase):
 x.foobar = 42
 self.assertEqual(x.foobar, 42)
 self.assertEqual(x.__dict__[foobar], 42)
+x.x = x
 
 with self.assertRaises(AttributeError):
 x.vararg


and you'll get a reference leak.
