* [3.10] Fix typos in the Include directory (GH-28745) (GH-28789)Christian Clauss2021-10-071-1/+1
| | | (cherry picked from commit 8e8f7522171ef82f2f5049940f815e00e38c6f42)
* bpo-42747: Remove Py_TPFLAGS_HAVE_AM_SEND and make ↵Miss Islington (bot)2021-07-231-14/+12
| | | | | | | | | | | | | | | Py_TPFLAGS_HAVE_VERSION_TAG no-op (GH-27260) (GH-27306) * Remove code that checks Py_TPFLAGS_HAVE_VERSION_TAG The field is always present in the type struct, as explained in the added comment. * Remove Py_TPFLAGS_HAVE_AM_SEND The flag is not needed, and since it was added in 3.10 it can be removed now. (cherry picked from commit a4760cc32d9e5dac7be262e9736eb30502cd7be3) Co-authored-by: Petr Viktorin <encukou@gmail.com>
* bpo-44378: Fix a compiler warning in Py_IS_TYPE() (GH-26644)Miss Islington (bot)2021-06-111-1/+3
| | | | | | | Py_IS_TYPE() no longer uses Py_TYPE() to avoid a compiler warning: no longer cast "const PyObject*" to "PyObject*". (cherry picked from commit 304dfec8d3c0763734ea8b5fa2af1d9e1ce69ffa) Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-43916: Add Py_TPFLAGS_DISALLOW_INSTANTIATION type flag (GH-25721)Victor Stinner2021-04-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new Py_TPFLAGS_DISALLOW_INSTANTIATION type flag to disallow creating type instances: set tp_new to NULL and don't create the "__new__" key in the type dictionary. The flag is set automatically on static types if tp_base is NULL or &PyBaseObject_Type and tp_new is NULL. Use the flag on the following types: * _curses.ncurses_version type * _curses_panel.panel * _tkinter.Tcl_Obj * _tkinter.tkapp * _tkinter.tktimertoken * _xxsubinterpretersmodule.ChannelID * sys.flags type * sys.getwindowsversion() type * sys.version_info type Update MyStr example in the C API documentation to use Py_TPFLAGS_DISALLOW_INSTANTIATION. Add _PyStructSequence_InitType() function to create a structseq type with the Py_TPFLAGS_DISALLOW_INSTANTIATION flag set. type_new() calls _PyType_CheckConsistency() at exit.
* bpo-43977: Use tp_flags for collection matching (GH-25723)Mark Shannon2021-04-301-0/+7
| | | | | | | | | | | | | * Add Py_TPFLAGS_SEQUENCE and Py_TPFLAGS_MAPPING, add to all relevant standard builtin classes. * Set relevant flags on collections.abc.Sequence and Mapping. * Use flags in MATCH_SEQUENCE and MATCH_MAPPING opcodes. * Inherit Py_TPFLAGS_SEQUENCE and Py_TPFLAGS_MAPPING. * Add NEWS * Remove interpreter-state map_abc and seq_abc fields.
* bpo-43908: Add Py_TPFLAGS_IMMUTABLETYPE flag (GH-25520)Erlend Egeberg Aasland2021-04-281-0/+3
| | | | | | Introduce Py_TPFLAGS_IMMUTABLETYPE flag for immutable type objects, and modify PyType_Ready() to set it for static types. Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-43753: Add Py_Is() and Py_IsNone() functions (GH-25227)Victor Stinner2021-04-101-0/+9
| | | | | | | Add the Py_Is(x, y) function to test if the 'x' object is the 'y' object, the same as "x is y" in Python. Add also the Py_IsNone(), Py_IsTrue(), Py_IsFalse() functions to test if an object is, respectively, the None singleton, the True singleton or the False singleton.
* bpo-43688: Support the limited C API in debug mode (GH-25131)Victor Stinner2021-04-021-14/+33
| | | | | | | | | | | | | The limited C API is now supported if Python is built in debug mode (if the Py_DEBUG macro is defined). In the limited C API, the Py_INCREF() and Py_DECREF() functions are now implemented as opaque function calls, rather than accessing directly the PyObject.ob_refcnt member, if Python is built in debug mode and the Py_LIMITED_API macro targets Python 3.10 or newer. It became possible to support the limited C API in debug mode because the PyObject structure is the same in release and debug mode since Python 3.8 (see bpo-36465). The limited C API is still not supported in the --with-trace-refs special build (Py_TRACE_REFS macro).

* bpo-39573: Convert Py_TYPE() and Py_SIZE() back to macros (GH-23366)Victor Stinner2020-11-181-9/+4
| | | | | | | | | This change partically reverts commit ad3252bad905d41635bcbb4b76db30d570cf0087 and the commit fe2978b3b940fe2478335e3a2ca5ad22338cdf9c. Many third party C extension modules rely on the ability of using Py_TYPE() to set an object type: "Py_TYPE(obj) = type;" or to set an object type using: "Py_SIZE(obj) = size;".
* bpo-42085: Introduce dedicated entry in PyAsyncMethods for sending values ↵Vladimir Matveev2020-11-101-0/+14
| | | | (#22780)
* bpo-42294: Add borrowed/strong reference to doc glossary (GH-23206)Victor Stinner2020-11-091-2/+3
| | | | | | Add "borrowed reference" and "strong reference" to the documentation glossary. Enhance also Py_INCREF() and Py_NewRef() documentation.
* bpo-42262: Add Py_NewRef() and Py_XNewRef() (GH-23152)Victor Stinner2020-11-051-3/+27
| | | | Added Py_NewRef() and Py_XNewRef() functions to increment the reference count of an object and return the object.

* Revert "bpo-40170: PyType_HasFeature() now always calls PyType_GetFlags() ↵Victor Stinner2020-07-081-2/+10
| | | | | (GH-19378)" (GH-21390) This partially reverts commit 45ec5b99aefa54552947049086e87ec01bc2fc9a.
* bpo-39573: Convert Py_REFCNT and Py_SIZE to functions (GH-20429)Victor Stinner2020-05-271-2/+17
| | | | | | | | | | | Convert Py_REFCNT() and Py_SIZE() macros to static inline functions. They cannot be used as l-value anymore: use Py_SET_REFCNT() and Py_SET_SIZE() to set an object reference count and size. Replace &Py_SIZE(self) with &((PyVarObject*)self)->ob_size in arraymodule.c. This change is backward incompatible on purpose, to prepare the C API for an opaque PyObject structure.
* bpo-39573: Convert Py_TYPE() to a static inline function (GH-20290)Dong-hee Na2020-05-251-1/+5

* bpo-38787: C API for module state access from extension methods (PEP 573) ↵Petr Viktorin2020-05-071-0/+5
| | | | | | | | | (GH-19936) Module C state is now accessible from C-defined heap type methods (PEP 573). Patch by Marcel Plch and Petr Viktorin. Co-authored-by: Marcel Plch <mplch@redhat.com> Co-authored-by: Victor Stinner <vstinner@python.org>

* bpo-40170: PyType_HasFeature() now always calls PyType_GetFlags() (GH-19378)Victor Stinner2020-04-071-4/+0
| | | | | | | | PyType_HasFeature() now always calls PyType_GetFlags() to hide implementation details. Previously, it accessed directly the PyTypeObject.tp_flags member when the limited C API was not used. Add fast inlined version _PyType_HasFeature() and _PyType_IS_GC() for object.c and typeobject.c.
* bpo-39573: Make Py_IS_TYPE() take constant parameters (GH-18799)Andy Lester2020-03-061-2/+3
| | | Add _PyObject_CAST_CONST() macro: cast a pointer to (const PyObject *).

* bpo-39573: Add Py_SET_SIZE() function (GH-18400)Victor Stinner2020-02-071-0/+5
| | | Add Py_SET_SIZE() function to set the size of an object.
* bpo-39573: Add Py_SET_TYPE() function (GH-18394)Victor Stinner2020-02-071-0/+6
| | | Add Py_SET_TYPE() function to set the type of an object.
* bpo-39573: Add Py_SET_REFCNT() function (GH-18389)Victor Stinner2020-02-071-0/+5
| | | | Add a Py_SET_REFCNT() function to set the reference counter of an object.
* bpo-39245: Make Vectorcall C API public (GH-17893)Petr Viktorin2020-02-061-1/+3
| | | | | | | | | | | | | | | | | * Add backcompat defines and move non-limited API declaration to cpython/ This partially reverts commit 2ff58a24e8a1c7e290d025d69ebaea0bbead3b8c which added PyObject_CallNoArgs to the 3.9+ stable ABI. This should not be done; there are enough other call APIs in the stable ABI to choose from. * Adjust documentation Mark all newly public functions as added in 3.9. Add a note about the 3.8 provisional names. Add notes on public API. * Put PyObject_CallNoArgs back in the limited API * Rename PyObject_FastCallDict to PyObject_VectorcallDict
* bpo-39542: Define PyTypeObject earlier in object.h (GH-18366)Victor Stinner2020-02-051-20/+16
| | | Replace "struct _typeobject" with PyTypeObject in object.h.
* bpo-39542: Convert PyType_Check() to static inline function (GH-18364)Victor Stinner2020-02-051-9/+22
| | | | Convert PyType_HasFeature(), PyType_Check() and PyType_CheckExact() macros to static inline functions.
* bpo-39542: Make PyObject_INIT() opaque in limited C API (GH-18363)Victor Stinner2020-02-051-14/+1
| | | | | | | | | | | | | | In the limited C API, PyObject_INIT() and PyObject_INIT_VAR() are now defined as aliases to PyObject_Init() and PyObject_InitVar() to make their implementation opaque. It avoids to leak implementation details in the limited C API. Exclude the following functions from the limited C API, move them from object.h to cpython/object.h: * _Py_NewReference() * _Py_ForgetReference() * _PyTraceMalloc_NewReference() * _Py_GetRefTotal()
* bpo-39542: Exclude trashcan from the limited C API (GH-18362)Victor Stinner2020-02-051-87/+0
| | | | | | | | Exclude trashcan mechanism from the limited C API: it requires access to PyTypeObject and PyThreadState structure fields, whereas these structures are opaque in the limited C API. The trashcan mechanism never worked with the limited C API. Move it from object.h to cpython/object.h.
* bpo-39542: Make _Py_NewReference() opaque in C API (GH-18346)Victor Stinner2020-02-051-19/+2
| | | | | | | | | | _Py_NewReference() becomes a regular opaque function, rather than a static inline function in the C API (object.h), to better hide implementation details. Move _Py_tracemalloc_config from public pymem.h to internal pycore_pymem.h header. Make _Py_AddToAllObjects() private.
* bpo-39542: Simplify _Py_NewReference() (GH-18332)Victor Stinner2020-02-031-27/+15
| | | | | | | | | * Remove _Py_INC_REFTOTAL and _Py_DEC_REFTOTAL macros: modify directly _Py_RefTotal. * _Py_ForgetReference() is no longer defined if the Py_TRACE_REFS macro is not defined. * Remove _Py_NewReference() implementation from object.c: unify the two implementations in object.h inline function. * Fix Py_TRACE_REFS build: _Py_INC_TPALLOCS() macro has been removed.
* bpo-39542: Move object.h debug functions to internal C API (GH-18331)Victor Stinner2020-02-031-7/+0
| | | | | | | | Move the following functions from the public C API to the internal C API: * _PyDebug_PrintTotalRefs(), * _Py_PrintReferenceAddresses() * _Py_PrintReferences()
* bpo-39489: Remove COUNT_ALLOCS special build (GH-18259)Victor Stinner2020-02-031-18/+2
| | | | | | | | | | | Remove: * COUNT_ALLOCS macro * sys.getcounts() function * SHOW_ALLOC_COUNT code in listobject.c * SHOW_TRACK_COUNT code in tupleobject.c * PyConfig.show_alloc_count field * -X showalloccount command line option * @test.support.requires_type_collecting decorator
* Py_DECREF: only pass filename if Py_REF_DEBUG is defined (GH-17870)Victor Stinner2020-01-081-5/+10
| | | | | | | Filename and line numbers are not needed when Py_REF_DEBUG are not defined. The static inline _Py_DECREF() function was introduced by commit 2aaf0c12041bcaadd7f2cc5a54450eefd7a6ff12.
* Typo fix in file Include/object.h (GH-14556)Hansraj Das2019-07-051-2/+2
| | | | * accross -> across * Extra space removed in comment
* 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
| | | Co-authored-by: Mark Shannon <mark@hotpy.org>
* 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
