No, there is the following caveat when cyclic Python references are involved: __dealloc__ is always called, but there is no guarantee that pure Python attributes are still set (they may be cleared, that is, set to None, in order to break cycles). Cython (cdef) attributes are still set. __del__ will not always be called, some garbage objects are skipped to break cycles. If __del__ is being called then all Python attributes are still set. TLDR: use __dealloc__ to destroy wrapped C++ objects. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
