[Python-Dev] PyObject_CallFunction and 'N' format char

Sun Jun 25 02:09:09 CEST 2006

 Sorry this is slightly offtopic, but I think it's important...
 According to recent experiments tracking down a memory leak, it
seems that PyObject_CallFunction(func, "N", object) and
PyObject_CallFunction(func, "O", object) are doing exactly the same
thing. However, documentation says "The C arguments are described
using a Py_BuildValue() style format string.". And of course
Py_BuildValue consumes one object reference, according to the
documentation and practice. However, PyObject_CallFunction does _not_
consume such an object reference, contrary to what I believed for
years. God knows how many leaks I may have introduced in my
bindings... :|
 Any comments?
