StateVector.get calling fetch can't handle bits

A call to StateVector.get that results in a fetch() raises a TypeError when the bits argument is used:

>>> from gwpy.timeseries import StateVector
>>> StateVector.get('L1:ISI-ETMX_ODC_CHANNEL_OUT_DQ', 'May 22 2014 14:00', 'May 22 2014 15:00', bits=range(8), verbose=True)
<class 'gwpy.timeseries.statevector.StateVectorDict'>
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/duncan.macleod/opt/gwpysoft/lib/python2.6/site-packages/gwpy/timeseries/core.py", line 344, in get
    **kwargs)[str(channel)]
  File "/home/duncan.macleod/opt/gwpysoft/lib/python2.6/site-packages/gwpy/timeseries/core.py", line 1026, in get
    verbose=verbose, **kwargs)
  File "/home/duncan.macleod/opt/gwpysoft/lib/python2.6/site-packages/gwpy/utils/deps.py", line 82, in wrapper
    return func(*args, **kwargs)
TypeError: fetch() got an unexpected keyword argument 'bits'

There are two possible fixes as far as I can see

  • overwrite StateVector.get to handle bits itself, or
  • overwrite StateVectorDict.fetch to handle bits
