Victor Stinner 9e23f0a27c [3.7] bpo-36389: _PyObject_IsFreed() now also detects uninitialized memory (GH-12770) (GH-12788) ... * bpo-36389: _PyObject_IsFreed() now also detects uninitialized memory (GH-12770) Replace _PyMem_IsFreed() function with _PyMem_IsPtrFreed() inline function. The function is now way more efficient, it became a simple comparison on integers, rather than a short loop. It detects also uninitialized bytes and "forbidden bytes" filled by debug hooks on memory allocators. Add unit tests on _PyObject_IsFreed(). (cherry picked from commit 2b00db6855) * bpo-36389: Change PyMem_SetupDebugHooks() constants (GH-12782) Modify CLEANBYTE, DEADDYTE and FORBIDDENBYTE constants: use 0xCD, 0xDD and 0xFD, rather than 0xCB, 0xBB and 0xFB, to use the same byte patterns than Windows CRT debug malloc() and free(). (cherry picked from commit 4c409beb4c)		2019-04-11 22:30:31 +02:00
