[Pyode-user] memory leaks

[Chris B. <chr...@gm...>]

Hi, the following code appears to leak Body and dict objects. Memprof
is available from 'svn co
http://svn.navi.cx/misc/trunk/python/memprof' (if anyone has a better
way of profiling python memory usage let me know!).


import ode

import memprof
sampler =3D memprof.Sampler()

sampler.run()
for i in range(1000):
    w =3D ode.World()
    body =3D ode.Body(w)
    # creating geom leads to 'dict' object leaks (_geom_c2py_lut ?)
    geom =3D ode.GeomCCylinder()
    # setBody leads to 'Body' object leaks
    geom.setBody(body)
    # no 'Body' leak if we set it back to None
    #geom.setBody(None)
    sampler.run()


I've looked at the pyode code. It appears that nothing is ever removed
from the global dictionary _geom_c2py_lut. Should this be done in geom
__dealloc__ ?

Similarly should geomobject __dealloc__ do 'del self.body'? Maybe it's
not necessary and geoms are being removed, it would appear that they
aren't from the profile, and yet what else other than the geom.body
reference could be keeping Body objects alive?

Thanks,
Chris
