[Python-modules-team] Bug#691713: python-pyrrd: Fails to create/use databases with spaces in the filename

[Elena Grandi]

Package: python-pyrrd
Version: 0.1.0-1
Severity: normal
Tags: upstream

Dear Maintainer,

When using the external backend, pyrrd does not properly sanitize the 
filename parameter passed to the shell and, for example, fails to use / 
create a database with spaces in the filename.

A simple example adapted from the doctests::

    >>> from pyrrd.rrd import DataSource, RRA, RRD
    >>> filename = 'a test.rrd'
    >>> dataSources = []
    >>> roundRobinArchives = []
    >>> dataSource = DataSource(dsName='speed', dsType='COUNTER', heartbeat=600)
    >>> dataSources.append(dataSource)
    >>> roundRobinArchives.append(RRA(cf='AVERAGE', xff=0.5, steps=1, rows=24))
    >>> myRRD = RRD(filename, ds=dataSources, rra=roundRobinArchives, start=92080440
    0)
    >>> myRRD.create()
    rrdtool create a test.rrd --start 920804400 --step 300 DS:speed:COUNTER:600:U:U 
    RRA:AVERAGE:0.5:1:24
    Traceback (most recent call last):
      File "<input>", line 1, in <module>
      File "/usr/lib/python2.7/dist-packages/pyrrd/rrd.py", line 175, in create

        raise ExternalCommandError(stderr.strip())
