* Typo fix in file Include/object.h (GH-14556)Hansraj Das2019-07-051-2/+2

* bpo-32388: Remove cross-version binary compatibility requirement in tp_flags ↵Antoine Pitrou2019-05-291-8/+10
| | | | | | | | (GH-4944) It is now allowed to add new fields at the end of the PyTypeObject struct without having to allocate a dedicated compatibility flag in tp_flags. This will reduce the risk of running out of bits in the 32-bit tp_flags value.
* bpo-36974: implement PEP 590 (GH-13185)Jeroen Demeyer2019-05-291-0/+5

* bpo-36922: implement PEP-590 Py_TPFLAGS_METHOD_DESCRIPTOR (GH-13338)Jeroen Demeyer2019-05-281-0/+3

* bpo-35983: skip trashcan for subclasses (GH-11841)Jeroen Demeyer2019-05-101-14/+37
| | | | | 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-36465: Make release and debug ABI compatible (GH-12615)Victor Stinner2019-04-241-7/+2
| | | | | | | | | | | | | | Release build and debug build are now ABI compatible: the Py_DEBUG define no longer implies Py_TRACE_REFS define which introduces the only ABI incompatibility. A new "./configure --with-trace-refs" build option is now required to get Py_TRACE_REFS define which adds sys.getobjects() function and PYTHONDUMPREFS environment variable. Changes: * Add ./configure --with-trace-refs * Py_DEBUG no longer implies Py_TRACE_REFS
* bpo-36527: silence -Wunused-parameter warnings in object.h (GH-12688)Dmitry Marakasov2019-04-061-0/+3

* bpo-35134: Don't define types twice in header files (GH-10754)Victor Stinner2018-11-271-12/+16
| | | | | | Fix the following clang warning: Include/cpython/pystate.h:217:3: warning: redefinition of typedef 'PyThreadState' is a C11 feature [-Wtypedef-redefinition]
* bpo-35134: Create Include/cpython/object.h (GH-10679)Victor Stinner2018-11-261-485/+6
| | | | | | | | * Move object.h code surrounded by "#ifndef Py_LIMITED_API" to a new Include/cpython/object.h header file. * "typedef struct _typeobject PyTypeObject;" is now always defined in object.h, but if Py_LIMITED_API is not defined, Include/cpython/object.h also defines the structure. * Complete the printfunc comment to mention Py_LIMITED_API define.
* bpo-35059: Add _PyObject_CAST() macro (GH-10645)Victor Stinner2018-11-221-11/+17
| | | | Add _PyObject_CAST() and _PyVarObject_CAST() macros to cast argument to PyObject* and PyVarObject* properly.
* bpo-35059: Convert _PyObject_GC_TRACK() to inline function (GH-10643)Victor Stinner2018-11-221-12/+15
| | | | | | | | | | | | | * Add _PyObject_ASSERT_FROM() and _PyObject_ASSERT_FAILED_MSG() macros. * PyObject_GC_Track() now calls _PyObject_ASSERT_FAILED_MSG(), instead of Py_FatalError(), if the object is already tracked, to dump more information on error. * _PyObject_GC_TRACK() no longer checks if the object is already tracked at runtime, use an assertion instead for best performances; PyObject_GC_Track() still checks at runtime. * pycore_object.h now includes pycore_pystate.h. * Convert _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() macros to inline functions.
* bpo-35059: Enhance _PyObject_AssertFailed() (GH-10642)Victor Stinner2018-11-211-3/+5
| | | | | | Enhance _PyObject_AssertFailed() * Exchange 'expr' and 'msg' parameters * 'expr' and 'func' arguments can now be NULL
* bpo-35230: dict: Remove some macros (GH-10513)INADA Naoki2018-11-141-2/+0
| | | | Remove _Py_REF_DEBUG_COMMA, DK_DEBUG_INCREF, and DK_DEBUG_DECREF. Convert DK_INCREF and DK_DECREF to static inline functions.
* bpo-35059: Convert _Py_Dealloc() to static inline function (GH-10223)Victor Stinner2018-10-301-6/+15
| | | | | Convert _Py_Dealloc() macro into a static inline function. Moreover, it is now also defined as a static inline function if Py_TRACE_REFS is defined.
* bpo-35059: Convert Py_XINCREF() to static inline function (GH-10224)Victor Stinner2018-10-291-13/+17
| | | | Convert Py_XINCREF() and Py_XDECREF() macros into static inline functions.
* bpo-35059: Convert Py_INCREF() to static inline function (GH-10079)Victor Stinner2018-10-291-29/+42
| | | | | * Convert Py_INCREF() and Py_DECREF() macros into static inline functions. * Remove _Py_CHECK_REFCNT() macro: code moved into Py_DECREF().
* bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ ↵Pablo Galindo2018-10-281-4/+4
| | | | | | | (GH-10152) Configuring python with ./configure --with-pydebug CFLAGS="-D COUNT_ALLOCS -O0" makes "make smelly" fail as some symbols were being exported without the "Py_" or "_Py" prefixes.
* bpo-35053: Define _PyTraceMalloc_NewReference in object.h (GH-10107)Victor Stinner2018-10-251-0/+4
| | | | | | _PyTraceMalloc_NewReference() is now called by _Py_NewReference(), so move its definition to object.h. Moreover, define it even if Py_LIMITED_API is defined, since _Py_NewReference() is also exposed even if Py_LIMITED_API is defined.
* bpo-9263: Dump Python object on GC assertion failure (GH-10062)Victor Stinner2018-10-251-0/+47
| | | | | | | | | | | | | | | | | | | | | | | Changes: * Add _PyObject_AssertFailed() function. * Add _PyObject_ASSERT() and _PyObject_ASSERT_WITH_MSG() macros. * gc_decref(): replace assert() with _PyObject_ASSERT_WITH_MSG() to dump the faulty object if the assertion fails. _PyObject_AssertFailed() calls: * _PyMem_DumpTraceback(): try to log the traceback where the object memory has been allocated if tracemalloc is enabled. * _PyObject_Dump(): log repr(obj). * Py_FatalError(): log the current Python traceback. _PyObject_AssertFailed() uses _PyObject_IsFreed() heuristic to check if the object memory has been freed by a debug hook on Python memory allocators. Initial patch written by David Malcolm. Co-Authored-By: David Malcolm <dmalcolm@redhat.com>
* bpo-35059: Add Py_STATIC_INLINE() macro (GH-10093)Victor Stinner2018-10-251-2/+2
| | | | | | | | | * 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.
* bpo-35053: Add Include/tracemalloc.h (GH-10091)Victor Stinner2018-10-251-0/+3
| | | | | | | * Modify object.h to ensure that pymem.h is included, to get _Py_tracemalloc_config variable. * Move _PyTraceMalloc_XXX() functions to tracemalloc.h, they need PyObject type. Break circular dependency between pymem.h and object.h.
* bpo-35053: Enhance tracemalloc to trace free lists (GH-10063)Victor Stinner2018-10-251-0/+3
| | | | | | | | | | | | tracemalloc now tries to update the traceback when an object is reused from a "free list" (optimization for faster object creation, used by the builtin list type for example). Changes: * Add _PyTraceMalloc_NewReference() function which tries to update the Python traceback of a Python object. * _Py_NewReference() now calls _PyTraceMalloc_NewReference(). * Add an unit test.
* bpo-9263: _PyObject_Dump() detects freed memory (GH-10061)Victor Stinner2018-10-231-0/+1
| | | | | | | | | _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.
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-251-2/+11
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()
* bpo-32544: Speed up hasattr() and getattr() (GH-5173)INADA Naoki2018-01-161-1/+3
| | | | | AttributeError was raised always when attribute is not found. This commit skip raising AttributeError when `tp_getattro` is `PyObject_GenericGetAttr`. It makes hasattr() and getattr() about 4x faster when attribute is not found.
* bpo-32030: Add more options to _PyCoreConfig (#4485)Victor Stinner2017-11-211-1/+0
| | | | | | Py_Main() now handles two more -X options: * -X showrefcount: new _PyCoreConfig.show_ref_count field * -X showalloccount: new _PyCoreConfig.show_alloc_count field
