* bpo-35992: Use PySequence_GetItem only if sq_item is not NULL (GH-11857)Miss Islington (bot)2019-02-171-2/+5
| | | | | | Not using `__class_getitem__()` fallback if there is a non-subcriptable metaclass was caused by a certain asymmetry between how `PySequenceMethods` and `PyMappingMethods` are used in `PyObject_GetItem`. This PR removes this asymmetry. No tests failed, so I assume it was not intentional.

| | | | | | | | | | | Fix a crash in slice_richcompare(): use strong references rather than stolen references for the two temporary internal tuples. The crash (or assertion error) occurred if a garbage collection occurred during slice_richcompare(), especially while calling PyObject_RichCompare(t1, t2, op).

* [3.7] bpo-9263: _PyObject_Dump() detects freed memory (GH-10061) (GH-10662)Victor Stinner2018-11-222-23/+76
| | | | | | | | | | | | | | | | | | | | | | | | * bpo-9263: _PyObject_Dump() detects freed memory (GH-10061) _PyObject_Dump() now uses an heuristic to check if the object memory has been freed: log "<freed object>" in that case. The heuristic rely on the debug hooks on Python memory allocators which fills the memory with DEADBYTE (0xDB) when memory is deallocated. Use PYTHONMALLOC=debug to always enable these debug hooks. (cherry picked from commit 82af0b63b07aa8d92b50098e382b458143cfc677) * bpo-9263: Fix _PyObject_Dump() for freed object (#10661) If _PyObject_Dump() detects that the object is freed, don't try to dump it (exit immediately). Enhance also _PyObject_IsFreed(): it now detects if the pointer itself looks like freed memory. (cherry picked from commit 2cf5d32fd9e61488e8b0be55a2e92a752ba8b06b)
