New issue 2041 by asmeurer: Doctest failures in Python 2.6.6
http://code.google.com/p/sympy/issues/detail?id=2041
See
http://groups.google.com/group/sympy/browse_thread/thread/de060bae007f0acb
for more information. The issue is that in Python 2.6.6, there are doctest
failures that do not exist in any other Python (including Python 2.6.5). I
have attached a file with all the failures. An example of some of the
failures is:
________________________________________________________________________________
_________________ sympy.assumptions.assume.AssumptionsContext

File "/Users/aaronmeurer/Documents/python/sympy/sympy-scratch2/sympy/assumptions/assume.py",
line

Failed example:
global_assumptions
Expected:
AssumptionsContext()
Got:
AssumptionsContext([])

986, in sympy.core.basic.Basic.match
Failed example:
e.match(p**q)
Expected:
{p_: x + y, q_: x + y}
Got:
{q_: x + y, p_: x + y}

And there are more. The problem is that if you change the doctest to give
what Python 2.6.6 wants, it will fail everywhere else. For example, right
now
$python2.7 bin/doctest sympy/assumptions/assume.py
passes, while
$python2.6.6 bin/doctest sympy/assumptions/assume.py
fails. But if you apply
diff --git a/sympy/assumptions/assume.py b/sympy/assumptions/assume.py
index f87d44f..0e31611 100644

Then
$python2.6.6 bin/doctest sympy/assumptions/assume.py
passes while
$python2.7 bin/doctest sympy/assumptions/assume.py
fails. So I do not know how to fix these things. By the way, the failures
in Python 2.6.6 release are exactly the same as the ones I attached to the
above named email to the mailing list from Python 2.6.6 rc1.
