* bpo-43908: Document Static Types in the C API (GH-25710)Victor Stinner2021-04-291-0/+2
| | | Update also PyTypeObject structure definition in the doc.
* bpo-40522: Replace PyThreadState_GET() with PyThreadState_Get() (GH-24575)Victor Stinner2021-02-191-1/+1
| | | | | Use directly the PyThreadState_Get() function in public header files, since PyThreadState_GET() macro is just an alias to it in pratice in these files.
* bpo-39465: Fix _PyUnicode_FromId() for subinterpreters (GH-20058)Victor Stinner2020-12-251-3/+4
| | | | | | | | | | | | | | | | | Make _PyUnicode_FromId() function compatible with subinterpreters. Each interpreter now has an array of identifier objects (interned strings decoded from UTF-8). * Add PyInterpreterState.unicode.identifiers: array of identifiers objects. * Add _PyRuntimeState.unicode_ids used to allocate unique indexes to _Py_Identifier. * Rewrite the _Py_Identifier structure. Microbenchmark on _PyUnicode_FromId(&PyId_a) with _Py_IDENTIFIER(a): [ref] 2.42 ns +- 0.00 ns -> [atomic] 3.39 ns +- 0.00 ns: 1.40x slower This change adds 1 ns per _PyUnicode_FromId() call in average.
* bpo-40170: Hide impl detail of Py_TRASHCAN_BEGIN macro (GH-23235)Hai Shi2020-11-241-1/+3
| | | | | The Py_TRASHCAN_BEGIN macro no longer accesses PyTypeObject attributes, but now can get the condition by calling the new private _PyTrash_cond() function which hides implementation details.
* bpo-40170: Fix PyType_Ready() refleak on static type (GH-23236)Victor Stinner2020-11-111-0/+1
| | | | | | | | | bpo-1635741, bpo-40170: When called on a static type with NULL tp_base, PyType_Ready() no longer increments the reference count of the PyBaseObject_Type ("object). PyTypeObject.tp_base is a strong reference on a heap type, but it is borrowed reference on a static type. Fix 99 reference leaks at Python exit (showrefcount 18623 => 18524).
* bpo-42085: Introduce dedicated entry in PyAsyncMethods for sending values ↵Vladimir Matveev2020-11-101-0/+3
| | | | (#22780)
* Add _PyType_GetModuleByDef (GH-22835)Petr Viktorin2020-11-031-0/+2
| | | | | See https://mail.python.org/archives/list/capi-sig@python.org/thread/T3P2QNLNLBRFHWSKYSTPMVEIL2EEKFJU/ for discussion. https://bugs.python.org/issue42100
* bpo-41991: Remove _PyObject_HasAttrId (GH-22629)Serhiy Storchaka2020-10-101-1/+0
| | | It can silence arbitrary exceptions.
* bpo-40989: Make _PyTraceMalloc_NewReference() internal (GH-20915)Victor Stinner2020-06-161-4/+0
| | | | Make the _PyTraceMalloc_NewReference() function fully internal: remove it from the public C API and don't export it anymore.
* bpo-39583: Remove superfluous "extern C" bits from Include/cpython/*.h ↵Skip Montanaro2020-06-011-8/+0
| | | | (GH-18413)
* bpo-39465: Remove _PyUnicode_ClearStaticStrings() from C API (GH-20078)Victor Stinner2020-05-131-1/+1
| | | | Remove the _PyUnicode_ClearStaticStrings() function from the C API. Make the function fully private (declare it with "static").
* bpo-38787: C API for module state access from extension methods (PEP 573) ↵Petr Viktorin2020-05-071-0/+1
| | | | | | | | | (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-39947: Hide implementation detail of trashcan macros (GH-18971)Victor Stinner2020-03-131-15/+18
| | | | | | Py_TRASHCAN_BEGIN_CONDITION and Py_TRASHCAN_END macro no longer access PyThreadState attributes, but call new private _PyTrash_begin() and _PyTrash_end() functions which hide implementation details.
* bpo-39571: Fix clang warning on PyTypeObject typedef (GH-18385)Victor Stinner2020-02-071-2/+2
| | | Only define PyTypeObject type once.
* bpo-39542: Convert PyType_Check() to static inline function (GH-18364)Victor Stinner2020-02-051-2/+0
| | | | 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 Stinner2020-02-051-0/+16
| | | | | | | | | | | | | | 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 Stinner2020-02-051-0/+86
| | | | | | | | 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-39543: Remove unused _Py_Dealloc() macro (GH-18361)Victor Stinner2020-02-051-10/+0
| | | | | | | | | | | | The macro is defined after Py_DECREF() and so is no longer used by Py_DECREF(). Moving _Py_Dealloc() macro back from cpython/object.h to object.h would require to move a lot of definitions as well: PyTypeObject and many related types used by PyTypeObject. Keep _Py_Dealloc() as an opaque function call to avoid leaking implementation details in the limited C API (object.h): remove _Py_Dealloc() macro from cpython/object.h.
* bpo-39489: Remove COUNT_ALLOCS special build (GH-18259)Victor Stinner2020-02-031-11/+0
| | | | | | | | | | | 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
* bpo-38631: Add _Py_NO_RETURN to functions calling Py_FatalError() (GH-18278)Victor Stinner2020-01-301-1/+1
| | | | | | | | | Add _Py_NO_RETURN to functions calling Py_FatalError(): * _PyObject_AssertFailed() * dummy_dealloc() * faulthandler_fatal_error_thread() * none_dealloc() * notimplemented_dealloc()
* bpo-37645: add new function _PyObject_FunctionStr() (GH-14890)Jeroen Demeyer2019-11-051-0/+1
| | | | | | | | | | | | Additional note: the `method_check_args` function in `Objects/descrobject.c` is written in such a way that it applies to all kinds of descriptors. In particular, a future re-implementation of `wrapper_descriptor` could use that code. CC @vstinner @encukou https://bugs.python.org/issue37645 Automerge-Triggered-By: @encukou
* bpo-37249: add declaration of _PyObject_GetMethod (GH-14015)Jeroen Demeyer2019-06-141-0/+3

* bpo-36974: implement PEP 590 (GH-13185)Jeroen Demeyer2019-05-291-7/+8
| | | | | Co-authored-by: Jeroen Demeyer <J.Demeyer@UGent.be> Co-authored-by: Mark Shannon <mark@hotpy.org>
* bpo-36389: Add _PyObject_CheckConsistency() function (GH-12803)Victor Stinner2019-04-121-0/+15
| | | | | | Add a new _PyObject_CheckConsistency() function which can be used to help debugging. The function is available in release mode. Add a 'check_content' parameter to _PyDict_CheckConsistency().
* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-111-3/+0
| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".
* bpo-35134: Create Include/cpython/object.h (GH-10679)Victor Stinner2018-11-261-0/+454
* 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.
