Notebook "load" or "attach" does not work

[nbruin]

If in a notebook I use:

%sh
cat > hello.spyx << EOF
def hello(name):
    """
    Print hello with the given name.
    """
    print("Hello %s"%name)
EOF

and then

load "hello.spyx"

the notebook hangs. In the server log I get:

  ...
  File "/usr/local/sage/default/local/lib/python2.5/site-packages/sage/server/notebook/worksheet.py", line 957, in _load_file
    t = self.do_sage_extensions_preparsing(t,
UnboundLocalError: local variable 't' referenced before assignment

This is not due to the file not being found: If I try to load or attach a non-existent file, I get an appropriate error message.

Component: notebook

Now, instead of an error, one gets a not implemented error. I've changed this from
defect to feature request.

Note the correct input should be:

%sh
cd
cat > hello.spyx << EOF
def hello(name):
    """
    Print hello with the given name.
    """
    print("Hello %s"%name)
EOF

load "hello.spyx"

I can reproduce the problem, but the error message has changed:

load "hello.spyx"
Error loading /tmp/Work2/sage-2.8.1/sage-2.8.1/hello.spyx -- file not
found

The spyx file can actually be found in $SAGE_ROOT/data/extcode/sage/hello.spyx

This bug also seems to be duplicate of #236.
