New submission from Barney Gale <[email protected]>:
>>> os.path.normpath('a/./b/../c//.')
'a/c'
>>> pathlib.Path('a/./b/../c//.')
PosixPath('a/b/../c')
pathlib takes care not to change the meaning of the path when normalising. That
means preserving '..' entries, as these can't be simplified without resolving
symlinks etc.
normpath(), on the other handle, /always/ eliminates '..' entries, which can
change the meaning of the path.
We could add a new argument to `normpath()` and `abspath()` that leaves '..'
entries intact. This was closed as "won't fix" back in bpo-2289, but I think
it's worth re-considering.
This enhancement would be helpful for my longer-term work to make pathlib an
OOP wrapper of os + os.path, rather than a parallel implementation.
