示例1: test_map_w_gced_element
# 需要导入模块: from transaction.weakset import WeakSet [as 别名]
# 或者: from transaction.weakset.WeakSet import map [as 别名]
def test_map_w_gced_element(self):

_orig = w.as_weakref_list
def _as_weakref_list():
# simulate race condition during iteration of list
# object is collected after being iterated.
result = _orig()
del dummy3[:]
gc.collect()
return result
w.as_weakref_list = _as_weakref_list
