我有一個(gè) C++ 類,它將 Python 模塊作為文件導(dǎo)入,并在返回接收到的數(shù)據(jù)之前連續(xù)調(diào)用它的函數(shù):ProgramLiveProcess::ProgramLiveProcess() { //Start Python to run the Program Python code Py_Initialize(); //Import the Program live processing module program_live_processing_module = PyImport_ImportModule(MODULE_NAME); //Get the objects for the functions to call live_process = PyObject_GetAttrString(program_live_processing_module, "Program_LiveProcess");}//Creates Python list from intensities arrayPyObject* ProgramLiveProcess::get_intensities_list(unsigned int intensities[INTENSITIES_DATA_SIZE]) { PyObjec* tr = PyList_New(0); for (int i = 0; i < INTENSITIES_DATA_SIZE; i++) { PyObject* ta = PyLong_FromLong(intensities[i]); PyList_Append(tr, ta); } return tr;}//TODO: Make this actually work//Frees objects in intensities Python list and the list itselfvoid ProgramLiveProcess::free_intensities_list(PyObject* i_list) { //std::cout << std::to_string(i_list->ob_refcnt) << std::endl; for (int i = 0; i < INTENSITIES_DATA_SIZE; i++) { PyObject* ta = PyList_GET_ITEM(i_list, i); Py_DECREF(ta); } Py_DECREF(i_list);}processed_data* ProgramLiveProcess::send_to_program_live_process(unsigned int intensities[INTENSITIES_DATA_SIZE], bool use_sensor_1) { //Call the Program_LiveProcess function PyObject* intensities_py = get_intensities_list(intensities); PyObject* calculate_args = PyTuple_Pack(2, intensities_py, use_sensor_1 ? Py_True : Py_False); //True or false depending on if using sensor 1 or 2 PyObject* processed_data_tuple = PyObject_CallObject(live_process, calculate_args); Py_DECREF(calculate_args); free_intensities_list(intensities_py); //Get the data from the function PyObject* s0p = PyTuple_GetItem(processed_data_tuple, 0); PyObject* s0t = PyTuple_GetItem(processed_data_tuple, 1);}雖然程序接收數(shù)據(jù)很好,但在不同條件下運(yùn)行時(shí),我在內(nèi)存泄漏和崩潰方面遇到了不一致的情況。雖然我無(wú)法提供堆棧跟蹤,但我想知道我在創(chuàng)建或取消引用 Python 對(duì)象方面是否做錯(cuò)了什么。通常,程序僅在我注釋掉 free_intensities_list 調(diào)用時(shí)運(yùn)行。
將列表作為參數(shù)發(fā)送時(shí)驗(yàn)證 Python 引用計(jì)數(shù)
尚方寶劍之說(shuō)
