#199 memory leak in sphere objects

Reported by yt_analysis (last edited )

Imported Ticket

  • Summary: memory leak in sphere objects
  • Component: yt
  • Milestone: 2.0
  • Reporter: britton
  • Owner: mturk
  • Resolution: worksforme
  • Status: closed
  • Created: 1236789728000000
  • Description: The following sequence of commands will result in a memory leak.

pf = EnzoStaticOutput('something')

sphere = pf.h.sphere(center,radius)

sphere['Density']

sphere.clear_data()

del sphere

Note: adding this before sphere.clear_data() helps, but does not appear to totally fix the problem. Adding it after that call has the same effect.

for g in pf.h.grids: g.clear_data()

  • Newvalue: This seems to be related to the child masks being kept around. I've committed a helpful fix, which doesn't completely fix the problem, in r1258, and we're bumping to the next version where we'll rethink child masks.
