[Python-modules-team] Bug#700571: python-psutil: Import fail

[Kevin Deldycke]

Package: python-psutil
Version: 0.5.1-1
Severity: important

As you can see below, the psutil package for Python distributed with Debian 7.0 doesn't work out of the box on my machine:

  server:~# python
  Python 2.7.3 (default, Jan  2 2013, 13:56:14)
  [GCC 4.7.2] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  >>> import psutil
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "/usr/lib/pymodules/python2.7/psutil/__init__.py", line 62, in <module>
      import psutil._pslinux as _psplatform
    File "/usr/lib/pymodules/python2.7/psutil/_pslinux.py", line 94, in <module>
      TOTAL_PHYMEM = _psutil_linux.get_sysinfo()[0]
  AttributeError: 'module' object has no attribute 'get_sysinfo'
  >>>

This machine is a virtual server powered by OpenVZ, which makes it lacks some meminfo:

  server:~# cat /proc/meminfo
  MemTotal:       16424968 kB
  MemFree:        16327960 kB
  SwapTotal:             0 kB
  SwapFree:              0 kB

This is the root cause of psutil failure.

Now, if I install a fresh version of psutil, it works:

  server:~# pip install psutil
