Hi,
I'm forwarding this message from sage-support to Cython-devel, where
it points out a probable bug in the Cython compiler (with fix).

Subject: [sage-support] cython and filenames
To: sage-support <[EMAIL PROTECTED]>
Here is a snippet of code from cython.py in the main tree
(SAGE_ROOT/devel/sage/sage/misc/cython.py)
def cython(filename, verbose=False, compile_message=False,
use_cache=False, create_local_c_file=False, annotate=True,
sage_namespace=True):
if not filename.endswith('pyx'):
print "File (=%s) should have extension .pyx"%filename
clean_filename = sanitize(filename)
====> base = os.path.split(os.path.splitext(clean_filename)[0])[1]
====> abs_base =
os.path.abspath(os.path.split(os.path.splitext(clean_filename)[0])[0])
It seems to me that the marked lines, in addition to being
hard to parse, do not have the intended effect. This is
because in the creation of clean_filename, the call to
the sanitize function converts all slashes and dots into
underscores, which are not 'picked up' by the calls to
the os.path.* functions.
Is this really what is intended?
Kate
