Xen devel - Sep 2009 - [PATCH] Fix memory leaks in libxc python bindings

Hi,

Reference counters are not correctly decreased for python object in several
places in python bindings for libxc. Most of them are around PyList_Append(),
which unlike PyList_SetItem() does increment reference counter of the object
being added to a list.

I am curious how did you find this? Is there a python
''valgrind'' that
can help track this? Or is there a python flag to be report such abnormalities?

None that I know of. I just used the source code. I found it because long
running xend managed by libvirt was consuming increasing amount of memory.
From the only repeatedly executed command virsh list I got to xm info and
xc_physinfo(). And then I just looked for all other calls to PyDict_* and
PyList_Append and fixed them.
