[New-bugs-announce] [issue7315] os.path.normpath doesn't normalize ../path/something.py

[James]

New submission from James <purpleidea at gmail.com>:

os.path.normpath doesn't normalize paths that start with ../
you would expect the final output line in the secpnd run to read:
"normpath: badnormpath.py" instead of: "normpath: ../tmp/badnormpath.py"

example:

james at home:~$ cd tmp/
james at home:~/tmp$ cat badnormpath.py 
#!/usr/bin/python

import os.path

print '__file__: %s' % __file__
print 'normpath: %s' % os.path.normpath(__file__)

james at home:~/tmp$ ./badnormpath.py 
__file__: ./badnormpath.py
normpath: badnormpath.py
james at home:~/tmp$ ./../tmp/badnormpath.py 
__file__: ./../tmp/badnormpath.py
normpath: ../tmp/badnormpath.py
james at home:~/tmp$
