memory leak in opencv python interface (Bug #1177)

I tried this code on openCV 2.2, the result is the same memory leak.

But I wonder if eendebakpt's code is resonable?
I know openCV integrate a numpy interface for their image,
but I think reasonable to call the function to convert numpy array to Matrix ( cv.fromarray(anumpyarray) ),
and eventually a cv.GetImage(mymatrix).

So far if you add a line in your exemple the memory leak disappear. (at least on 2.2, I notice I patched my version so the cv.fromarray() doesn't leak, which I think should have been integrated in 2.3)

eendebakpt you can try the following, I let you confirm, and also change the status following your idea.

import sys
import cv
import numpy as np

frame=np.zeros( (640,480)).astype('uint8')

n=0
while True:
n=n+1
if n>500:
break;
print('%d' % n)
frame0=frame.copy()
mat=cv.fromarray(frame0) # if you add this line,
sz=cv.GetSize(mat) # there is no more memory leak
#no need for a del in my opinion.

cheers.

Adding the line suggested by joemanu indeed removes the memory leak (2.3rc). However, if passing numpy arrays to the opencv functions directly is an option, then there should be no memory leaks (or at least functions to clear the memory).
I changed the status to minor, but leave it as a defect.
