[New-bugs-announce] [issue15286] normpath does not work with local literal paths

[Manuel de la Pena]

New submission from Manuel de la Pena <manuel at canonical.com>:

Local literal paths are those paths that do use the \\?\ that allows to have paths longer that the MAX_PATH set by Windows (http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247%28v=vs.85%29.aspx#short_vs._long_names).

While UNC (http://en.wikipedia.org/wiki/Path_%28computing%29) paths should not be normalized, local paths that do use the \\?\ prefix should so that developers that use such a trink to allow longer paths on windows do not have to wrapp the call in the following way:

LONG_PATH_PREFIX = '\\?\'
path = path.replace(LONG_PATH_PREFIX, '')
result = LONG_PATH_PREFIX + os.path.normpath(path)

The possible solution would be for the normalization to work and return the path normalized with the prefix added.
