* bpo-38500: Add _PyInterpreterState_SetEvalFrameFunc() (GH-17340)Victor Stinner2020-03-124-4/+12
| | | | | | | | | | | | PyInterpreterState.eval_frame function now requires a tstate (Python thread state) parameter. Add private functions to the C API to get and set the frame evaluation function: * Add tstate parameter to _PyFrameEvalFunction function type. * Add _PyInterpreterState_GetEvalFrameFunc() and _PyInterpreterState_SetEvalFrameFunc() functions. * Add tstate parameter to _PyEval_EvalFrameDefault().
* bpo-38631: _PyGILState_Init() returns PyStatus (GH-18908)Victor Stinner2020-03-101-1/+1
| | | | _PyGILState_Init() now returns PyStatus rather than calling Py_FatalError() on failure.
* bpo-34822: Simplify AST for subscription. (GH-9605)Serhiy Storchaka2020-03-101-30/+11
| | | | | | | | | * Remove the slice type. * Make Slice a kind of the expr type instead of the slice type. * Replace ExtSlice(slices) with Tuple(slices, Load()). * Replace Index(value) with a value itself. All non-terminal nodes in AST for expressions are now of the expr type.
* bpo-39877: Deprecate PyEval_InitThreads() (GH-18892)Victor Stinner2020-03-101-2/+2
| | | | Deprecated PyEval_InitThreads() and PyEval_ThreadsInitialized(). Calling PyEval_InitThreads() now does nothing.
* bpo-39877: PyGILState_Ensure() don't call PyEval_InitThreads() (GH-18891)Victor Stinner2020-03-101-0/+1
| | | | | | | | PyGILState_Ensure() doesn't call PyEval_InitThreads() anymore when a new Python thread state is created. The GIL is created by Py_Initialize() since Python 3.7, it's not needed to call PyEval_InitThreads() explicitly. Add an assertion to ensure that the GIL is already created.
* bpo-39877: Py_Initialize() pass tstate to PyEval_InitThreads() (GH-18884)Victor Stinner2020-03-091-0/+2

* bpo-39877: Remove useless PyEval_InitThreads() calls (GH-18883)Victor Stinner2020-03-091-3/+0
| | | | Py_Initialize() calls PyEval_InitThreads() since Python 3.7. It's no longer needed to call it explicitly.
* bpo-38249: Expand Py_UNREACHABLE() to __builtin_unreachable() in the release ↵Serhiy Storchaka2020-03-091-3/+7

* bpo-39882: Py_FatalError() logs the function name (GH-18819)Victor Stinner2020-03-072-1/+11
| | | | | | | | | | | | The Py_FatalError() function is replaced with a macro which logs automatically the name of the current function, unless the Py_LIMITED_API macro is defined. Changes: * Add _Py_FatalErrorFunc() function. * Remove the function name from the message of Py_FatalError() calls which included the function name. * Update tests.
* bpo-39877: _PyRuntimeState.finalizing becomes atomic (GH-18816)Victor Stinner2020-03-071-6/+17
| | | | | | | | | | | | Convert _PyRuntimeState.finalizing field to an atomic variable: * Rename it to _finalizing * Change its type to _Py_atomic_address * Add _PyRuntimeState_GetFinalizing() and _PyRuntimeState_SetFinalizing() functions * Remove _Py_CURRENTLY_FINALIZING() function: replace it with testing directly _PyRuntimeState_GetFinalizing() value Convert _PyRuntimeState_GetThreadState() to static inline function.
* 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-39639: Remove the AST "Suite" node and associated code (GH-18513)Batuhan Taşkaya2020-03-041-7/+1
| | | | | | | | The AST "Suite" node is no longer used and it can be removed from the ASDL definition and related structures (compiler, visitors, ...).

| | | | | | | | | | | | Move CPython C API from Include/fileutils.h into a new Include/cpython/fileutils.h header file which is included by Include/fileutils.h. Exclude the following private symbols from the limited C API: * _Py_error_handler * _Py_GetErrorHandler() * _Py_DecodeLocaleEx() * _Py_EncodeLocaleEx()
* bpo-35134: Add Include/cpython/bytesobject.h file (GH-18494)Victor Stinner2020-02-124-140/+145
| | | | | | | | | Add Include/cpython/bytearrayobject.h and Include/cpython/bytesobject.h header files. Move CPython C API from Include/bytesobject.h into a new Include/cpython/bytesobject.h header file which is included by Include/bytesobject.h. Do a similar change for Include/bytearrayobject.h.
* bpo-35081: Move dtoa.h header to the internal C API (GH-18489)Victor Stinner2020-02-122-5/+8
| | | | | | | Move the dtoa.h header file to the internal C API as pycore_dtoa.h: it only contains private functions (prefixed by "_Py"). The math and cmath modules must now be compiled with the Py_BUILD_CORE macro defined.
* bpo-35081: Move bytes_methods.h to the internal C API (GH-18492)Victor Stinner2020-02-121-0/+4
| | | | | Move the bytes_methods.h header file to the internal C API as pycore_bytes_methods.h: it only contains private symbols (prefixed by "_Py"), except of the PyDoc_STRVAR_shared() macro.
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bulk of this patch was generated automatically with: for name in \ PyObject_Vectorcall \ Py_TPFLAGS_HAVE_VECTORCALL \ PyObject_VectorcallMethod \ PyVectorcall_Function \ PyObject_CallOneArg \ PyObject_CallMethodNoArgs \ PyObject_CallMethodOneArg \ ; do echo $name git grep -lwz _$name | xargs -0 sed -i "s/\b_$name\b/$name/g" done old=_PyObject_FastCallDict new=PyObject_VectorcallDict git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g" and then cleaned up: - Revert changes to in docs & news - Revert changes to backcompat defines in headers - Nudge misaligned comments

* bpo-39245: Make Vectorcall C API public (GH-17893)Petr Viktorin2020-02-062-15/+26
| | | | | | | | | | | | | | | | | * 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-39127: Make _Py_HashPointer's argument be const (GH-17690)Andy Lester2020-02-051-1/+1

* 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.
* Add PyInterpreterState.fs_codec.utf8 (GH-18367)Victor Stinner2020-02-051-0/+1
| | | | | | Add a fast-path for UTF-8 encoding in PyUnicode_EncodeFSDefault() and PyUnicode_DecodeFSDefaultAndSize(). Add _PyUnicode_FiniEncodings() helper function for _PyUnicode_Fini().
* 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 Stinner2020-02-052-11/+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 Stinner2020-02-054-45/+62
| | | | | | | | | | | | | | 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 Stinner2020-02-052-87/+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-39542: Make _Py_NewReference() opaque in C API (GH-18346)Victor Stinner2020-02-053-54/+36
| | | | | | | | | | _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 Stinner2020-02-032-7/+9
| | | | | | | | 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 Stinner2020-02-033-30/+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
* 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-38631: Avoid Py_FatalError() in init_slotdefs() (GH-18263)Victor Stinner2020-01-301-0/+1
| | | | | | Rename init_slotdefs() to _PyTypes_InitSlotDefs() and add a return value of type PyStatus. The function is now called exactly once from _PyTypes_Init(). Replace calls to init_slotdefs() with an assertion checking that slotdefs is initialized.
* bpo-39320: Handle unpacking of **values in compiler (GH-18141)Mark Shannon2020-01-271-2/+2
| | | | | | | | | | | | | * Add DICT_UPDATE and DICT_MERGE bytecodes. Use them for ** unpacking. * Remove BUILD_MAP_UNPACK and BUILD_MAP_UNPACK_WITH_CALL, as they are now unused. * Update magic number for ** unpacking opcodes. * Update dis.rst to incorporate new bytecodes. * Add blurb entry.
