* [3.8] bpo-36389: Backport debug enhancements from master (GH-16796)Victor Stinner2019-10-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612) bpo-36389, bpo-38376: The _PyObject_CheckConsistency() function is now also available in release mode. For example, it can be used to debug a crash in the visit_decref() function of the GC. Modify the following functions to also work in release mode: * _PyDict_CheckConsistency() * _PyObject_CheckConsistency() * _PyType_CheckConsistency() * _PyUnicode_CheckConsistency() Other changes: * _PyMem_IsPtrFreed(ptr) now also returns 1 if ptr is NULL (equals to 0). * _PyBytesWriter_CheckConsistency() now returns 1 and is only used with assert(). * Reorder _PyObject_Dump() to write safe fields first, and only attempt to render repr() at the end. (cherry picked from commit 6876257eaabdb30f27ebcbd7d2557278ce2e5705) * bpo-36389: Fix _PyBytesWriter in release mode (GH-16624) Fix _PyBytesWriter API when Python is built in release mode with assertions. (cherry picked from commit 60ec6efd96d95476fe5e38c491491add04f026e5) * bpo-38070: Enhance visit_decref() debug trace (GH-16631) subtract_refs() now pass the parent object to visit_decref() which pass it to _PyObject_ASSERT(). So if the "is freed" assertion fails, the parent is used in debug trace, rather than the freed object. The parent object is more likely to contain useful information. Freed objects cannot be inspected are are displayed as "<object at xxx is freed>" with no other detail.

* [3.8] bpo-37879: Suppress subtype_dealloc decref when base type is a C heap ↵Petr Viktorin2019-09-121-0/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | type (GH-15323, GH-16004) (GH-15966) The instance destructor for a type is responsible for preparing an instance for deallocation by decrementing the reference counts of its referents. If an instance belongs to a heap type, the type object of an instance has its reference count decremented while for static types, which are permanently allocated, the type object is unaffected by the instance destructor. Previously, the default instance destructor searched the class hierarchy for an inherited instance destructor and, if present, would invoke it. Then, if the instance type is a heap type, it would decrement the reference count of that heap type. However, this could result in the premature destruction of a type because the inherited instance destructor should have already decremented the reference count of the type object. This change avoids the premature destruction of the type object by suppressing the decrement of its reference count when an inherited, non-default instance destructor has been invoked. Finally, an assertion on the Py_SIZE of a type was deleted. Heap types have a non zero size, making this into an incorrect assertion. https://github.com/python/cpython/pull/15323.

| | | | | | | Replace two Python function calls with a single one to ensure that no memory allocation is done between the invalid object is created and when _PyObject_IsFreed() is called. (cherry picked from commit 3bf0f3ad2046ac674d8e8a2c074a5a8b3327797d)

| | | | | _Py_AddPendingCall(). (gh-13714)" (GH-13780) This reverts commit 6a150bcaeb190d1731b38ab9c7a5d1a352847ddc.
* bpo-36974: Make tp_call=PyVectorcall_Call work for inherited types (GH-13699)Petr Viktorin2019-06-021-5/+25
| | | | | | | | | | | | | | | | | | When inheriting a heap subclass from a vectorcall class that sets `.tp_call=PyVectorcall_Call` (as recommended in PEP 590), the subclass does not inherit `_Py_TPFLAGS_HAVE_VECTORCALL`, and thus `PyVectorcall_Call` does not work for it. This attempts to solve the issue by: * always inheriting `tp_vectorcall_offset` unless `tp_call` is overridden in the subclass * inheriting _Py_TPFLAGS_HAVE_VECTORCALL for static types, unless `tp_call` is overridden * making `PyVectorcall_Call` ignore `_Py_TPFLAGS_HAVE_VECTORCALL` This means it'll be ever more important to only call `PyVectorcall_Call` on classes that support vectorcall. In `PyVectorcall_Call`'s intended role as `tp_call` filler, that's not a problem.

| | | | | Add new trashcan macros to deal with a double deallocation that could occur when the `tp_dealloc` of a subclass calls the `tp_dealloc` of a base class and that base class uses the trashcan mechanism. Patch by Jeroen Demeyer.
* bpo-36611: Disable serialno field of debug memory allocators (#12796)Victor Stinner2019-04-121-2/+2
| | | | | | | | | | | Omit serialno field from debug hooks on Python memory allocators to reduce the memory footprint by 5%. Enable tracemalloc to get the traceback where a memory block has been allocated when a fatal memory error is logged to decide where to put a breakpoint. Compile Python with PYMEM_DEBUG_SERIALNO defined to get back the field.

* bpo-33608: Factor out a private, per-interpreter _Py_AddPendingCall(). ↵Eric Snow2019-04-121-1/+1
| | | | | (gh-12360) This is effectively an un-revert of #11617 and #12024 (reverted in #12159). Portions of those were merged in other PRs (with lower risk) and this represents the remainder. Note that I found 3 different bugs in the original PRs and have fixed them here.
* bpo-36389: Change PyMem_SetupDebugHooks() constants (GH-12782)Victor Stinner2019-04-111-4/+4
| | | | | 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().
* bpo-36389: _PyObject_IsFreed() now also detects uninitialized memory (GH-12770)Victor Stinner2019-04-111-0/+23
| | | | | | | | | 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().
* bpo-35059: Enhance _PyObject_AssertFailed() (GH-10642)Victor Stinner2018-11-211-1/+1

| | | | | | | | | * Add Py_STATIC_INLINE() macro to declare a "static inline" function. If the compiler supports it, try to always inline the function even if no optimization level was specified. * Modify pydtrace.h to use Py_STATIC_INLINE() when WITH_DTRACE is not defined. * Add an unit test on Py_DECREF() to make sure that _Py_NegativeRefcount() reports the correct filename.
