[Pysparse-users] ll_mat.__getitem__ still leaks lots of memory

[Rob S. <rs...@MI...>]

I saw that Łukasz Pankowski submitted a fix for a memory leak in
ll_mat. I updated my copy of pysparse (from the new-setup-py branch),
but I'm still getting a memory leak.

Here's an easy way to reproduce it:

from pysparse.sparse.spmatrix import ll_mat
mat = ll_mat(1000,1000)
mat[0,0] = 1
for i in xrange(100000): m = mat[0,:]
for i in xrange(100000): m = mat[0,:]
...

If I repeat that last line indefinitely, I lose about 400 MB of memory
each time.
