* bpo-45061: Detect Py_DECREF(Py_True) bug (GH-28089)Victor Stinner2021-08-312-7/+11
| | | | | Add a deallocator to the bool type to detect refcount bugs in C extensions which call Py_DECREF(Py_True) or Py_DECREF(Py_False) by mistake.

* bpo-44990: Change layout of evaluation frames. "Layout B" (GH-27933)Mark Shannon2021-08-253-25/+11
| | | Places the locals between the specials and stack. This is the more "natural" layout for a C struct, makes the code simpler and gives a slight speedup (~1%)

* Fix a SystemError in code.replace() (#27771)Guido van Rossum2021-08-161-3/+5
| | | | | | | While the comment said 'We don't bother resizing localspluskinds', this would cause .replace() to crash when it happened. (Also types.CodeType(), but testing that is tedious, and this tests all code paths.)

| | | | | | | | | | | | | | | | | (GH-27530) * Unify the C and Python implementations of OrderedDict.popitem(). The C implementation no longer calls ``__getitem__`` and ``__delitem__`` methods of the OrderedDict subclasses. * Change popitem() and pop() methods of collections.OrderedDict For consistency with dict both implementations (pure Python and C) of these methods in OrderedDict no longer call __getitem__ and __delitem__ methods of the OrderedDict subclasses. Previously only the Python implementation of popitem() did not call them.

| | | | | | | | | | | | | | * Convert "specials" array to InterpreterFrame struct, adding f_lasti, f_state and other non-debug FrameObject fields to it. * Refactor, calls pushing the call to the interpreter upward toward _PyEval_Vector. * Compute f_back when on thread stack, only filling in value when frame object outlives stack invocation. * Move ownership of InterpreterFrame in generator from frame object to generator object. * Do not create frame objects for Python calls. * Do not create frame objects for generators.

| | | | | | | | (GH-27165) The non-GC-type branch of subtype_dealloc is using the type of an object after freeing in the same unsafe way as GH-26274 fixes. (I believe the old news entry covers this change well enough.) https://bugs.python.org/issue44184
* bpo-42073: allow classmethod to wrap other classmethod-like descriptors (#27115)Łukasz Langa2021-07-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch by Erik Welch. bpo-19072 (#8405) allows `classmethod` to wrap other descriptors, but this does not work when the wrapped descriptor mimics classmethod. The current PR fixes this. In Python 3.8 and before, one could create a callable descriptor such that this works as expected (see Lib/test/test_decorators.py for examples): ```python class A: @myclassmethod def f1(cls): return cls @classmethod @myclassmethod def f2(cls): return cls ``` In Python 3.8 and before, `A.f2()` return `A`. Currently in Python 3.9, it returns `type(A)`. This PR make `A.f2()` return `A` again. As of #8405, classmethod calls `obj.__get__(type)` if `obj` has `__get__`. This allows one to chain `@classmethod` and `@property` together. When using classmethod-like descriptors, it's the second argument to `__get__`--the owner or the type--that is important, but this argument is currently missing. Since it is None, the "owner" argument is assumed to be the type of the first argument, which, in this case, is wrong (we want `A`, not `type(A)`). This PR updates classmethod to call `obj.__get__(type, type)` if `obj` has `__get__`. Co-authored-by: Erik Welch <erik.n.welch@gmail.com>
