#5922: doctesting sage tree does not work when SAGE_ROOT is a symbolic link
---------------------+------------------------------------------------------
Reporter: was | Owner: mabshoff
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.2
Component: doctest | Keywords:
---------------------+------------------------------------------------------
If you make a symbolic link to SAGE_ROOT, then doctesting will not work at
all:

}}}
The reason for this is related to *my* bugfix for testing files outside
the tree. Basically, that we're in the tree is not detected correctly in
the case of symlinks, so the doctest program decides we are not in the
tree, hence tries to import the function. This, of course, fails.
Ideas for solutions:
1. Use a different command line option for testing outside tree.
2. Improve detection of whether or not in Sage tree.
