Comment (by SimonKing):
I am not sure what the two doc tests are supposed to demonstrate, as they
just test against errors being raised.
Anyway, with #11791 (plus dependencies plus something more, so, someone
else should cross verify), I get
{{{
sage: from sage.misc.sageinspect import sage_getsourcelines
sage: class Foo: pass
....:
sage: sage_getsourcelines(Foo) # Is it intended to fix this?
Traceback (most recent call last):
...
IOError: could not find class definition
sage: import inspect
sage: inspect.findsource(Sets.ParentMethods) # Why is Python's inspect
module tested??
Traceback (most recent call last):
...
IOError: could not find class definition
sage: L = sage_getsourcelines(Sets.ParentMethods) # works just fine
sage: print ''.join(L[0])
class ParentMethods:
# # currently overriden by the default implementation in
sage.structure.Parent
# def __call__(self, *args, **options):
# return self.element_class(*args, **options)
# Todo: simplify the _element_constructor definition logic
...
"""
if category is None:
category = self.category()
from sage.combinat.free_module import CombinatorialFreeModule
return CombinatorialFreeModule(base_ring, self, category =
category.Algebras(base_ring))
}}}
The code line that is changed in your patch is not touched by #11791. So,
how does it actually change things?
