Jeremy Hylton	30c9f3991c	Variety of small INC/DECREF patches that fix reported memory leaks ... with free variables. Thanks to Martin v. Loewis for finding two of the problems. This fixes SF buf 405583. There is also a C API change: PyFrame_New() is reverting to its pre-2.1 signature. The change introduced by nested scopes was a mistake. XXX Is this okay between beta releases? cell_clear(), the GC helper, must decref its reference to break cycles. frame_dealloc() must dealloc all cell vars and free vars in addition to locals. eval_code2() setup code must INCREF cells it copies out of the closure. The STORE_DEREF opcode implementation must DECREF the object it passes to PyCell_Set().	2001-03-13 01:58:22 +00:00
Jeremy Hylton	fbd849f201	PEP 227 implementation ... A cell contains a reference to a single PyObject. It could be implemented as a mutable, one-element sequence, but the separate type has less overhead.	2001-01-25 20:04:14 +00:00
