This seems to be some problem with ipython, because if I push a
function that works, e.g.:
def get_tests():
    pass
    #from sympy.utilities.runtests import PyTestReporter, SymPyTests
    #r = PyTestReporter(verbose, tb, colors)
    #t = SymPyTests(r, kw, post_mortem)
    #t.add_paths(["sympy/core"])
    #tests = t.collect_tests_in_file(t._tests[0])
    #return tests
from IPython.kernel import client
mec = client.MultiEngineClient()
mec.reset()
ids = mec.get_ids()
mec.push_function({"get_tests": get_tests})
try:
    print mec.execute("get_tests()")
except:
    t, v, tr = sys.exc_info()
    print t
    print v
    print tr
    print dir(v)
    v.raise_exception()


Then it prints:

[0] In [1]: get_tests()
[1] In [1]: get_tests()
[2] In [1]: get_tests()
[3] In [1]: get_tests()
[4] In [1]: get_tests()
[5] In [1]: get_tests()
[6] In [1]: get_tests()
[7] In [1]: get_tests()


But if I push the following function:

def get_tests():
    pass
    from sympy.utilities.runtests import PyTestReporter, SymPyTests

Then it prints the error from my previous email. The problem is
however that sympy is not in my sys.path so it should raise a regular
import error exception.

To prove my theory, here is a simple script, that fails for me:


----------
import sys

def fails():
    e = 1/0

from IPython.kernel import client
mec = client.MultiEngineClient()
mec.reset()
ids = mec.get_ids()
mec.push_function({"f": fails})
try:
    print mec.execute("get_tests()")
except:
    t, v, tr = sys.exc_info()
    print v
    v.raise_exception()
-----------


I am using python2.6, since this is what is default in ubuntu now. If
you have time, I'll provide you with ssh access to my computer so that
you can debug this yourself.

I originally wanted to go for a beer tonight, but this makes me
reconsider. :) I need to get the parallel testing working soon, since
I won't have a time for this later.
