Logging in Sage doesn't work at all:
{{{
sage: log_text()
---------------------------------------------------------------------------
AttributeError Traceback (most recent call
last)
<ipython-input-1-732188d3c286> in <module>()
----> 1 log_text()
/home/itaibn-nobackup/sage/devel/local/lib/python2.7/site-
packages/sage/misc/log.pyc in __init__(self, dir, debug, viewer)
93 self._dir = dir
94 self._filename = os.path.join(dir, self._filename())
---> 95 self._output = __IPYTHON__.output_hist
96 self._input = __IPYTHON__.input_hist_raw
97 self._text = ''
AttributeError: 'bool' object has no attribute 'output_hist'
}}}
This is because the module `misc.log` uses the variable `__IPYTHON__`,
which meant something different in older versions of IPython.
