* bpo-43770: Refactor PyType_Ready() function (GH-25336)Victor Stinner2021-04-111-0/+4
| | | | | | * Split PyType_Ready() into sub-functions. * type_ready_mro() now checks if bases are static types earlier. * Check tp_name earlier, in type_ready_checks(). * Add _PyType_IsReady() macro to check if a type is ready.
* bpo-43268: Replace _PyThreadState_GET() with _PyInterpreterState_GET() ↵Victor Stinner2021-02-191-5/+5
| | | | | | | | | | | (GH-24576) Replace _PyThreadState_GET() with _PyInterpreterState_GET() in functions which only need the current interpreter, but don't need the current Python thread state. Replace also _PyThreadState_UncheckedGet() with _PyThreadState_GET() in faulthandler.c, since _PyThreadState_UncheckedGet() is just an alias to _PyThreadState_GET() in practice.
* bpo-42979: Enhance abstract.c assertions checking slot result (GH-24352)Victor Stinner2021-01-271-0/+6
| | | | | | | | * bpo-42979: Enhance abstract.c assertions checking slot result Add _Py_CheckSlotResult() function which fails with a fatal error if a slot function succeeded with an exception set or failed with no exception set: write the slot name, the type name and the current exception (if an exception is set).
* bpo-42745: Make the type cache per-interpreter (GH-23947)Victor Stinner2020-12-261-0/+3
| | | | | | | | | | | Make the type attribute lookup cache per-interpreter. Add private _PyType_InitCache() function, called by PyInterpreterState_New(). Continue to share next_version_tag between interpreters, since static types are still shared by interpreters. Remove MCACHE macro: the cache is no longer disabled if the EXPERIMENTAL_ISOLATED_SUBINTERPRETERS macro is defined.
* bpo-35059: Enhance _PyObject_GC_TRACK() macros (GH-20931)Victor Stinner2020-06-171-14/+34
| | | | | * Rename _PyObject_GC_TRACK_impl() to _PyObject_GC_TRACK() * Rename _PyObject_GC_UNTRACK_impl() to _PyObject_GC_UNTRACK() * Omit filename and lineno parameters if NDEBUG is defined.
* bpo-40989: Make _PyTraceMalloc_NewReference() internal (GH-20915)Victor Stinner2020-06-161-0/+6
| | | | Make the _PyTraceMalloc_NewReference() function fully internal: remove it from the public C API and don't export it anymore.
* bpo-40989: PyObject_INIT() becomes an alias to PyObject_Init() (GH-20901)Victor Stinner2020-06-151-6/+31
| | | | | | | | | | | | | | The PyObject_INIT() and PyObject_INIT_VAR() macros become aliases to, respectively, PyObject_Init() and PyObject_InitVar() functions. Rename _PyObject_INIT() and _PyObject_INIT_VAR() static inline functions to, respectively, _PyObject_Init() and _PyObject_InitVar(), and move them to pycore_object.h. Remove their return value: their return type becomes void. The _datetime module is now built with the Py_BUILD_CORE_MODULE macro defined. Remove an outdated comment on _Py_tracemalloc_config.
* bpo-40170: Convert PyObject_IS_GC() macro to a function (GH-19464)Hai Shi2020-04-141-0/+9
|
* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-1/+3
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-40170: PyType_HasFeature() now always calls PyType_GetFlags() (GH-19378)Victor Stinner2020-04-071-1/+10
| | | | | | | | 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-40170: PyObject_GET_WEAKREFS_LISTPTR() becomes a function (GH-19377)Victor Stinner2020-04-061-0/+7
| | | | | | | | Convert the PyObject_GET_WEAKREFS_LISTPTR() macro to a function to hide implementation details: the macro accessed directly to the PyTypeObject.tp_weaklistoffset member. Add _PyObject_GET_WEAKREFS_LISTPTR() static inline function to the internal C API.
* bpo-39542: Declare _Py_AddToAllObjects() in pycore_object.h (GH-18368)Victor Stinner2020-02-051-0/+1
| | | | | | _Py_AddToAllObjects() is used in bltinmodule.c and typeobject.c when Py_TRACE_REFS is defined. Fix Py_TRACE_REFS build.
* bpo-39542: Move object.h debug functions to internal C API (GH-18331)Victor Stinner2020-02-031-0/+9
| | | | | | | | Move the following functions from the public C API to the internal C API: * _PyDebug_PrintTotalRefs(), * _Py_PrintReferenceAddresses() * _Py_PrintReferences()
* bpo-36854: Move _PyRuntimeState.gc to PyInterpreterState (GH-17287)Victor Stinner2019-11-201-1/+1
| | | | | * Rename _PyGC_InitializeRuntime() to _PyGC_InitState() * finalize_interp_clear() now also calls _PyGC_Fini() in subinterpreters (clear the GC state).
* bpo-36854: gcmodule.c gets its state from tstate (GH-17285)Victor Stinner2019-11-201-4/+6
| | | | | | | | | * Add GCState type for readability * gcmodule.c now gets its gcstate from tstate * _PyGC_DumpShutdownStats() now expects tstate rather than runtime * Rename "state" to "gcstate" for readability: to avoid confusion between "state" and "tstate" for example. * collect() now only expects tstate: it gets gcstate from tstate. * Pass tstate to _PyErr_xxx() functions
* bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)Victor Stinner2019-10-071-1/+0
| | | | | | | | | | | | | | | | | | | | | 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.
* bpo-38353: Cleanup includes in the internal C API (GH-16548)Victor Stinner2019-10-021-1/+1
| | | | Use forward declaration of types to avoid includes in the internal C API. Add also comment to justify other includes.
* Revert "bpo-36818: Add PyInterpreterState.runtime field. (gh-13129)" (GH-13795)Victor Stinner2019-06-041-4/+3
| | | This reverts commit 396e0a8d9dc65453cb9d53500d0a620602656cfe.
* bpo-36818: Add PyInterpreterState.runtime field. (gh-13129)Eric Snow2019-06-011-3/+4

* bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853)Victor Stinner2019-04-171-2/+2
| | | | | | | | | | | | | | | | | | | | Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros of pyport.h when Py_BUILD_CORE_MODULE is defined. The Py_BUILD_CORE_MODULE define must be now be used to build a C extension as a dynamic library accessing Python internals: export the PyInit_xxx() function in DLL exports on Windows. Changes: * Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply Py_BUILD_CORE directy in pyport.h. * ceval.c compilation now fails with an error if Py_BUILD_CORE is not defined, just to ensure that Python is build with the correct defines. * setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define. * setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather than Py_BUILD_CORE_BUILTIN define * PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.
* bpo-36389: Add _PyObject_CheckConsistency() function (GH-12803)Victor Stinner2019-04-121-0/+4
| | | | | | 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-35059: Add _PyObject_CAST() macro (GH-10645)Victor Stinner2018-11-221-2/+2
| | | | 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 Stinner2018-11-221-24/+46
| | | | | | | | | | | | | * 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-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-211-0/+56
Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
