Issue1879935

On windows XP prof SP2:


C:\Python23>python.exe
Python 2.3.5 (#62, Feb  8 2005, 16:23:02) [MSC v.1200 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.path.isabs('/a')
True
>>> os.path
<module 'ntpath' from 'C:\Python23\lib\ntpath.pyc'>
>>>



C:\dist>jython.bat
Jython 2.3a0 on java1.6.0_04
Type "copyright", "credits" or "license" for more information.
>>> import os
>>> os.path.isabs('/a')
False
>>> os.path
<module 'javapath' from 'C:\dist\Lib\javapath.py'>
>>>

Another difference: os.path.isabs('\\') on cPython returns True while on Jython returns False.
I guess there are other differences like these.

Note: on Windows '\\' is an alias for the current drive letter. For example: if the current working directory is D:\Documents, os.path.realpath('\\') returns "D:\\" (which is obviously absolute).

fixed in r4171: we use the platform dependent path module (ntpath on 
Windows) now

I installed the most updated Jython version from the trunk and I'm still
noticing the same problem.

It seems that the ntpath module is not actually used:

>>> import os
>>> os.path
<module 'javapath' from 'C:\dist\Lib\javapath.py'>
>>>

That's the problem you're having then, the fact that ntpath isn't being 
used. I'm not sure why it wouldn't work on your environment. Are you 
sure that's trunk?

What version of Windows are you using? What is the value of 
java.lang.System.getProperty('os.name')

Here's what I get:

C:\Documents and Settings\Administrator\Desktop\jython-
trunk>.\jython.bat
Jython 2.3a0+ (trunk, Jun 8 2008, 14:43:44)
[Java HotSpot(TM) Client VM (Sun Microsystems Inc.)] on java1.6.0_05
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.path
<module 'ntpath' from 'C:\Documents and 
Settings\Administrator\Desktop\jython-tr
unk\dist\Lib\ntpath.py'>
>>> os.path.isabs('/a')
True
>>>

You're right, I'm sorry.
I wasn't using the latest trunk version.
A question: what happens on other systems than Windows? Is javapath.py
still used?

posixpath is used on everything else but windows -- which is pretty much 
what CPython does (except it checks for os2 and windows ce)

javapath shouldn't be in use by Jython at all, actually (which should 
have told me you're not on trunk). The module is still included for 
backwards compat.

I'll assume the other related bugs are still fixed
