* bpo-45256: Avoid C calls for most Python to Python calls. (GH-28937)Mark Shannon2021-10-181-153/+97
| | | | | | * Avoid making C calls for most calls to Python functions. * Change initialize_locals(steal=true) and _PyTuple_FromArraySteal to consume the argument references regardless of whether they succeed or fail.
* bpo-43760: Add PyThreadState_EnterTracing() (GH-28542)Victor Stinner2021-10-151-10/+7
| | | | | | | | | | Add PyThreadState_EnterTracing() and PyThreadState_LeaveTracing() functions to the limited C API to suspend and resume tracing and profiling. Add an unit test on the PyThreadState C API to _testcapi. Add also internal _PyThreadState_DisableTracing() and _PyThreadState_ResetTracing().

* bpo-45340: Don't create object dictionaries unless actually needed (GH-28802)Mark Shannon2021-10-131-36/+36
| | | | | | | | | | | | | | * Never change types' cached keys. It could invalidate inline attribute objects. * Lazily create object dictionaries. * Update specialization of LOAD/STORE_ATTR. * Don't update shared keys version for deletion of value. * Update gdb support to handle instance values. * Rename SPLIT_KEYS opcodes to INSTANCE_VALUE.
* pycore_pystate.h no longer redefines PyThreadState_GET() (GH-28921)Victor Stinner2021-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | Redefining the PyThreadState_GET() macro in pycore_pystate.h is useless since it doesn't affect files not including it. Either use _PyThreadState_GET() directly, or don't use pycore_pystate.h internal C API. For example, the _testcapi extension don't use the internal C API, but use the public PyThreadState_Get() function instead. Replace PyThreadState_Get() with _PyThreadState_GET(). The _PyThreadState_GET() macro is more efficient than PyThreadState_Get() and PyThreadState_GET() function calls which call fail with a fatal Python error. posixmodule.c and _ctypes extension now include <windows.h> before pycore header files (like pycore_call.h). _PyTraceback_Add() now uses _PyErr_Fetch()/_PyErr_Restore() instead of PyErr_Fetch()/PyErr_Restore(). The _decimal and _xxsubinterpreters extensions are now built with the Py_BUILD_CORE_MODULE macro defined to get access to the internal C API.
* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-121-2/+2
| | | | | | | * Move _PyObject_CallNoArgs() to pycore_call.h (internal C API). * _ssl, _sqlite and _testcapi extensions now call the public PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs(). * _lsprof extension is now built with Py_BUILD_CORE_MODULE macro defined to get access to internal _PyObject_CallNoArgs().
* bpo-45439: Rename _PyObject_CallNoArg() to _PyObject_CallNoArgs() (GH-28891)Victor Stinner2021-10-111-5/+5
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* Restore PEP 523 functionality. (GH-28871)Mark Shannon2021-10-111-4/+2
