Victor Stinner ace47d7efd Issue #18408: PyEval_EvalFrameEx() and PyEval_CallObjectWithKeywords() now fail
with an assertion error if they are called with an exception set
(PyErr_Occurred()).

If these functions are called with an exception set, the exception may be
cleared and so the caller looses its exception.

Add also assertions to PyEval_CallObjectWithKeywords() and call_function() to
check if the function succeed with no exception set, or the function failed
with an exception set.

Victor Stinner 26f91999b4 Close #18469: Replace PyDict_GetItemString() with _PyDict_GetItemId() in structseq.c
_PyDict_GetItemId() is more efficient: it only builds the Unicode string once.
Identifiers (dictionary keys) are now created at Python initialization, and if
the creation failed, Python does exit with a fatal error.

Before, PyDict_GetItemString() failure was not handled: structseq_new() could
call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could
also crash.

Victor Stinner 78e2c985ac Issue #18408: Fix show_warning(), clear also the exception raised by
_Py_DisplaySourceLine()

For example, _PyGC_DumpShutdownStats() calls PyErr_WarnExplicitFormat() while
the import machinery does not work anymore, _Py_DisplaySourceLine() fails when
trying to import the io module.

Don't pass a NULL traceback to PyException_SetTraceback(): pass Py_None.
Passing NULL would raise a new exception.

Brett Cannon 0075110ab2 Issue #18364: Stop using the ImportError._not_found hack.
The private attribute was leaking out of importlib and led to at least
one person noticing it. Switch to another hack which won't leak
outside of importlib and is nearly as robust.
