Comment (by cnassau):
Replying to [comment:6 leif]:
> Well, I meant `/jehova` shouldn't be "resolved" to `//`. The problem
with `sage-location` is just a consequence of doing so.
But `/jehova` ***does*** resolve to `/`, not `//`.
It seems {{{pwd}}} is to blame here:
{{{
cn@jehova:/waste/cn/sage> pwd
/waste/cn/sage
cn@jehova:/waste/cn/sage> pwd -L
/waste/cn/sage
cn@jehova:/waste/cn/sage> pwd -P
//waste/cn/sage-5.6
}}}
But maybe this is {{{HIS}}} way to let me know, that {{{HE}}} doesn't want
to point to '/', either...
I wonder why {{{./sage}}} uses the {{{-P}}} variant:
{{{
# Make SAGE_ROOT absolute
SAGE_ROOT=`cd "$SAGE_ROOT" && pwd -P`
if [ $? -ne 0 ]; then
echo >&2 "$0: cannot determine SAGE_ROOT directory"
exit 1
fi
}}}
Probably this is normalizing the path somehow, which is probably a good
thing and shouldn't be changed.
The real question is if there is a problem with using 'os.path.samefile'
in 'sage-location'. According to the python docs that function only works
under unix but that probably covers all Sage supported platforms for the
foreseeable future, doesn't it?
