New issue 3272 by [email protected]: Python 3.3 test failures
http://code.google.com/p/sympy/issues/detail?id=3272
There are many test failures in Python 3.3. It's still in alpha stage, so
you have to download it from python.org (see
http://python.org/download/releases/3.3.0/). Unfortunately, there are
binaries only for Mac OS X and Windows, so on Linux you'll have to compile
it (but don't worry, it's straight forward to compile, and doesn't take
long).
Here is a preliminary of some of the test failures. It isn't all of them
because the test hang, and the doctests crash.

KeyboardInterrupt
The last traceback is because I had to interrupt in the hanging test in
test_expand.py. I haven't tried running the remaining tests yet. For the
doctests, we get:
sympy/concrete/products.py[4] ....
[OK]
sympy/concrete/summations.py[6] ......
[OK]

TypeError: metaclass conflict: the metaclass of a derived class must be a
(non-strict) subclass of the metaclasses of all its bases
and the test runner crashes at that point.
The likely reason for most of the test failures is that Python 3.3 enables
hash randomization by default, which means that the hash of objects is now
randomly determined when the interpreter starts up. Therefore, we need to
run the tests in Python 3.3 multiple times to make sure that everything
really works.
Also, we need to see if it's possible to print the random hash seed with
the tests and input it manually, to aid fixing future failures caused by
this.
