New submission from Campbell Barton <ideasma...@gmail.com>: This patch was made on python r74276
Often when writing in C/Python I want to append to a list within a C loop of an unknown length. When this is done for newly created PyObject (which is quite common) - you need to assign each item to a variable and then decref it. eg: PyObject *item= PyFloat_FromDouble(x); PyList_Append(list, item); Py_DECREF(item); I have seen people make mistakes with this (in pygame code and blender3d), and run PyList_Append(list, PyFloat_FromDouble(x)), ofcourse this is not the fault of python/c api that devs do not read docs properly but I think it would be very convenient to have an append that works in a similar way to PyList_SET_ITEM This simple patch allows... PyList_APPEND(list, PyFloat_FromDouble(x)) doc included. ---------- files: py3_APPEND.diff keywords: patch messages: 91167 nosy: ideasman42 severity: normal status: open title: PyList_APPEND (append without incref) versions: Python 3.2 Added file: http://bugs.python.org/file14619/py3_APPEND.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6616> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
