Re: python-libvirt for 0.9.3 leaking file descriptors

i've reported this issue before, so i guess this is a regression. looks
like the python bindings for 0.9.3 are leaking file descriptors:

root@cloud1:~# python
Python 2.6.6 (r266:84292, Dec 26 2010, 22:31:48) 
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import libvirt
libvirt.getVersion()

9003

def openclose():

...     c = libvirt.open('qemu:///system')
...     c.close()
... 

import os
os.system('lsof -p %d | wc -l' % os.getpid())

37

openclose()
os.system('lsof -p %d | wc -l' % os.getpid())

40

openclose()
os.system('lsof -p %d | wc -l' % os.getpid())

43

every time I open and close a connection to libvirt, i loose 3 file
descriptors. these are a socket and two fifo pipes. i'm using the -3
build on debian sid.

can someone test this on a fedora machine? curious if this is something
inside libvirt or a problem with the build...

thanks,

Hello Igor,

I don't see this problem on my FC15, I'm using the git HEAD.
