Doh! It turned out the strange effect was due to my particular build
process.
My Python
Can be run like this:
ghaer...@ws124~/src/gh/test$ python3 setup.py build_ext --inplace
running build_ext
building 'foo' extension
gcc -fno-strict-aliasing -g -fwrapv -O0 -Wall -Wstrict-prototypes -
arch i386 -m32 -I/opt/jetstream/include/python3.1 -c foo.c -o build/
temp.macosx-10.4-i386-3.1-pyde
Maybe somebody can enlighten me here. I can't figure out why doing a
rich comparison on my object decreases the total reference count by 1.

For the most part, I understand the theory behind reference counting in
Python C code. But there is one thing that I am confused about and I
have not been able to clear it up.
Let say that you have the following function (over-simplified):

t found an easy way to determine if said
dictionary contents are still in use (so it is ok to delete them from
the dictionary). I've thought about creating a dict subclass that counts
the number of assignments and deletions but that seems cumbersome (an
bug-prone).

Hi,
I have a problem with the reference count after an error occurs
in a script which I execute as follows..
PyObject* lDict = PyDict_New();
PyDict_SetItemString(lDict, "item", (PyObject*)iItem->mPyObject);
PyObject* lResult = PyEval_EvalCode(mCode, ScnGlobal::sDictionary,
lDict);

Because the name 'A' is no longer associated with the class object.
However, self has a reference to the cla

i'm starting work and a simple database layer and wanted to use the

Hi all, i'm working on an app that embed python 2.3
with Gnu/Linux, and i'd like to have some precisions:
I'm making python's modules to extend my
application's functions with a built in script editor.
At now all works very well, but i'd like to know if
