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

Dear Maintainer,

python-pyrrd as currently found in wheezy and sid has a bug, known upstream 
(<https://code.google.com/p/pyrrd/issues/detail?id=26>) which breaks 
the RRD.fetch method, preventing the user from getting data out of an RRD.

With some boilerplate taken from the package doctests, this is a 
way to trigger the bug:

    >>> import os, tempfile
    >>> from pyrrd.rrd import DataSource, RRA, RRD
    >>> dss = []
    >>> rras = []
    >>> rrdfile = tempfile.NamedTemporaryFile()
    >>> dss.append(DataSource(dsName='speed', dsType='COUNTER', heartbeat=600))
    >>> rras.append(RRA(cf='AVERAGE', xff=0.5, steps=1, rows=24))
    >>> rras.append(RRA(cf='AVERAGE', xff=0.5, steps=6, rows=10))
    >>> rrd = RRD(rrdfile.name, ds=dss, rra=rras, start=920804400)
    >>> rrd.create()
    >>> rrd.bufferValue('920805600', '12363')
    >>> rrd.bufferValue('920805900', '12363')
    >>> rrd.update()
    >>> rrd.fetch()
    Traceback (most recent call last):
      File "<input>", line 1, in <module>
      File "/usr/lib/python2.7/dist-packages/pyrrd/rrd.py", line 226, in fetch
        return self.backend.fetch(*data)[returnStyle]
    TypeError: fetch() takes exactly 2 arguments (3 given)
