Garbage generation (1.4.2 - Mac OS 10.9.5 - Python 2.7.5)

[paschembri]

The use of the local["xyz"] seems to generate uncollectable garbage. I tried the following :

>>> from plumbum import local
>>> ls = local['ls']
>>> ls['-l']()
...
>>> del ls
>>> import gc
>>> gc.collect()
10
>>> gc.garbage
[<subprocess.Popen object at 0x10b459790>]

Then I tried just with subprocess :

>>> import subprocess
>>> subprocess.check_output(['ls', '-l'])
...
>>> import gc
>>> gc.collect()
0
>>> gc.garbage
[]

I also tried with

>>> ls.run('-l')

and it also generates garbage.

I'll look into it ; could you confirm that you have the same behavior ?
