Py_SetProgramName is deprecated since 3.11 and there is no planned direct replacement. There is a recommendation of using PyConfig, which implies a more verbose approach, so we drop the lines instead of replacing it. This: Py_SetProgramName(L"module-test"); can be replaced by: PyStatus status; PyConfig config; PyConfig_InitPythonConfig(&config); status = PyConfig_SetString(&config, &config.program_name, program_name); if (PyStatus_Exception(status)) { goto exception; } status = Py_InitializeFromConfig(&config); if (PyStatus_Exception(status)) { goto exception; } exception: PyConfig_Clear(&config); Py_ExitStatusException(status); Note: PyConfig's approach is not part of the Stable ABI, meaning it will not be possible to use it once Py_SetProgramName is removed in 3.13 Change-Id: I0734d502469ae4f28f4c211bdfbfdbeae82b1375 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@qt.io>
