Please post a ticket on trac. I suspect it will affect only linux/OS X.

Not sure the best approach to fix it at this point.

Cheers,
Jonathan

This problem seems to be fixed with the latest SVN version of the SVN repo installer. Or at least worked around.

Judging by the bug report, you probably don't need me to tell you how to check it out, but the next guy googling might Smile

Code:
cd ~/.xbmc/plugins/programs
svn co http://xbmc-addons.googlecode.com/svn/trunk/plugins/programs/SVN%20Repo%20Installer/

Had the same problem as you using every other version of the repo installer. This works like a charm on Karmic x64.

the answer is in: do NOT link with external python.

http://trac.xbmc.org/ticket/7291

perhaps someone could mark this with [SOLVED].

That's hardly a solution... I thought we were moving towards more external libs, not less...

Perhaps xbmc should provide a 'better' function that resembles / imitates the behavior we DO need.

sure, but that is something for trac tickets to handle, in my opinion.

This is the intended behavior of os.getcwd(). It returns the path of the directory the python interpreter was started from, in this case, the path to XBMC.

The same thing would happen on windows if we used external python there, too.

The solution is to set a plugin constant to os.path.dirname(sys.argv[0]) or os.path.dirname(__file__) or use the inspect module, or to call os.path.dirname(sys.argv[0]) each time you want the path to your plugin.

IMO something like __base_dir__ = os.path.dirname(sys.argv[0]); BASE_DIR = sys.modules["__main__"].__base_dir__ is the most attractive and readable way of doing things.

Your alternatives:
PHP Code:
#default.py
import sys
import os
import inspect

#plugin constants
__plugin__ = 'Test'
__base_dir1__ = os.path.dirname(sys.argv[0])
__base_dir2__ = os.path.dirname(__file__)


if __name__ == '__main__':
    print '\n\ndefault.py'
    print 'os.getcwd():', os.getcwd()
    print 'sys.argv[0]:', sys.argv[0]
    print '__file__:', __file__
    print 'inspect.currentframe().f_code.co_filename', inspect.currentframe().f_code.co_filename


    import resources.lib.bar 

PHP Code:
#bar.py
import sys
import os
import inspect

print '\n\nBAR.PY'
print 'os.getcwd():', os.getcwd()
print 'sys.argv[0]:', sys.argv[0]
print '__file__:', __file__
print 'inspect.currentframe().f_code.co_filename', inspect.currentframe().f_code.co_filename
print ''
print 'Getting the Head Directory of your Addon from bar.py:'
print 'os.path.dirname(sys.argv[0])', os.path.dirname(sys.argv[0])
print 'sys.modules["__main__"].__base_dir1__', sys.modules['__main__'].__base_dir1__
print 'sys.modules["__main__"].__base_dir2__', sys.modules['__main__'].__base_dir2__
