os.path.basename() - only Windows OR *nix?

[Thomas Ploch]

Hello,

I have a cgi script that handles fileuploads from windows and *nix
machines. i need os.path.basename(filename) to get the pure filename.

For *nix, thats not a problem, but for windows, it always returns the
full path:

#/usr/bin/env python

import cgi, os
import cgitb; cgitb.enable()

form = cgi.FieldStorage()
filename = os.path.basename(form['uploadfile'].filename)

print 'Content-Type: text/html\n\n'
print filename

-----------------

For 'C:\text\text.txt', the output is 'C:\text\text.txt', which should
be 'text.txt', the same happens for 'C:\\text\\text.txt'. I think its
the escapes that makes python not splitting it. All Unix style paths get
converted the right way.

Is there an easy way around this, or do I really have to write a parser
including _all_ Python escapes?

Let me guess : your cgi script is running on *n*x ?-)

Probably.

>>fnames = "C:\\dir\\data.ext", "/dir/data.txt", "dir:data"
import ntpath, posixpath, macpath
def basename(filename):

.... for m in ntpath, posixpath, macpath:
.... if m.sep in filename:
.... return m.basename(filename)
.... else:
.... # XXX
.... raise SomeException('could not do the job')
....

>>for f in fnames:

.... print f, basename(f)
....
C:\dir\data.ext data.ext
/dir/data.txt data.txt
dir:data data

>>>

Might need some improvements, but you get the idea...

Pretty hard to get this one, heh? :-D

Good that you decided I was worth the information.

Thnaks a lot. :)
