Torsten Landschoff added the comment:
Prompted by Emanuel's comment I ran the test with repetitions. This does not
actually test his assertion that I missed a decref since he referred to the
error case when setting the __doc__ key of the instance dict fails. But I was
curious none the less.
I was shocked that this failed with
```
torsten@defiant:~/mirror/cpython$ make test TESTOPTS="-R 3:2 test_property"
...
test test_property failed -- Traceback (most recent call last):
File "/home/torsten/mirror/cpython/Lib/test/test_property.py", line 172, in
test_property_decorator_doc_writable
self.assertEqual(sub.__class__.spam.__doc__, 'Eggs')
AssertionError: 'Spam' != 'Eggs'
```
But this was not introduced by my changes, rather it is an existing bug in the
tests: test_property_decorator_doc_writable modifies a class created on module
level so the second repetition sees the already updated class.
fix_repetitions.diff contains a fix for this problem (by defining the class
locally in the test method).
While at it I introduced a refleak on purpose and this is correctly reported by
the tests. Good to know how to test for this :-)
