Bug Report + Fix: os.path.normpath

[Andrew Cooke]

Hi,

On NT using 1.5.2 I see the following:

import os.path
print os.path.normpath(r'.\\a\b')
\a\b

which looks wrong (I expect a\b, which is the output for r'.\a\b')

To fix this, change:
        elif comps[i] == '' and i > 0 and comps[i-1] <> '':
            del comps[i]
to
        elif comps[i] == '':
            del comps[i]

within normpath in Libs\ntpath.py (it's obvious where once you look at
the routine)

I can't work out what the check is for in the old version, as the
modified code seems to work OK for all cases I can think of - but I'm
worried it is there for a reason.

The same code appears in posixpath and so the same error will be seen on
Unix.

Cheers,

Andrew
