| os.path.join('c:', r'\\server\share') returns c:\\server\share rather than \\server\share. Interestingly os.path.join('c:a', r'\\server\share') returns r'\\server\share'. IMHO, r'\\server\share' should be returned in all cases. |

| Logged In: YES user_id=1188172 This is a difficult issue, since as far as I recall Windows allows two or more backslashes in a row in the middle of normal paths. |

| Logged In: YES user_id=1188172 I'd recommend not to change the behaviour, but add a note in the docs that UNCs are not recognized as such in os.path.join. |

| Logged In: YES user_id=22785 If the current behavior is kept, then os.path.join can't be relied upon to return the 2nd (or 3rd+) argument if that argument is an absolute path. This is one of the things I rely on os.path.join to do and would need to write my own version. Also, the behavior is quite different if the first agument contains more than simply the drive letter. I know this is a difficult issue and that is why I would like to see it fixed in the standard library. My question is whether there is a rationale for the current behavior. |

| Seems to be fixed in python3.1. See #5799. This is not backported for 2.x yet. (Or it won't happen) |

| Can the fix be backported to 2.7 or can this be closed? |

| I say close it since it is a change in behavior and shouldn't go in a point release. I'm happy to see it fixed in 3.1. |

| It seems that joining UNC path to a directory root fails: Python 2.7.3 (default, Sep 26 2012, 21:51:14) [GCC 4.7.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from ntpath import join >>> join('c:\\', '\\\\server\\mount\\dir') 'c:\\\\server\\mount\\dir' When the first argument contains also something else everything works fine: >>> join('c:\\dir', '\\\\server\\mount\\dir') '\\\\server\\mount\\dir' I would say this is a bug. Obviously fixing this changes behavior, but I have hard time believing that anyone relies on the current buggy output. On the other hand, I was today reported a bug in my software that was caused by this. Funny thing was that the bug was in code that was added as a workaround for issue #3426 (i.e. use `join(os.getcwdu(), path)` instead of `abspath(path)` when path is Unicode). Luckily adding another workaround for this issue is pretty easy. |
