When I add an object created locally to a mapping or sequence (that will
be returned from a function into an running instance of the Python
interpreter), I need to call Py_DECREF on the object, right?
Unfortunately, I really feel like the following code leaks memory...
--- for example ---
PyObject* list = Py_Buildvalue("[]");
while(go) {
PyObject* num = Py_BuildValue("i", 10);
PyList_Append(list, num);
Py_DECREF(num);
}
return list;
/* The responsibility of decrementing the list now lies within the scope
of Python. */
--- end example ---
Secondly, __and most importantly__, does anyone have any tools and/or
recommendations for detecting memory leaks when writing extension
modules in C? I've been using printf() and showing the OBJECT->ob_refcnt
(which, is always 1 when I'm "done" with the pointer?) but this seems
fairly newb.
I'm mostly asking so I can cleanup any craziness in my code before I try
and release pyiw (the Python bindings for Wireless Networking in Linux).
I really want it to be as clean as possible before showing anyone
else. :)
