Issue1111

Code:

def load_modules(dir, module_prefix = None):
    files = os.listdir(dir)
    files.sort()
    for filename in files:
        if not filename.endswith('.py') or not filename[0:1].isupper():
            continue

        file = filename[:-3]
        if module_prefix == None:
            mod = __import__(file, fromlist=filename)
        else:
            mod = __import__('%s.%s' % (module_prefix, file),
fromlist=filename)

        c = getattr(mod, file)
        o = c()
        info(o) // prints information about the module/class

path = "/home/wesleys/sbox/blpython/src/lib/OSS/bladelogic"
load_modules(path, "OSS.bladelogic")

Running this code in python (2.5.1) works as expected, with jython it
fails.. 

2.2.1:
Traceback (innermost last):
  File "test_logic.py", line 48, in ?
  File "test_logic.py", line 38, in load_modules
TypeError: __import__() takes no keyword arguments

2.5a1:
Traceback (most recent call last):
  File "test_logic.py", line 48, in <module>
    load_modules(path, "OSS.bladelogic")
  File "test_logic.py", line 38, in load_modules
    mod = __import__('%s.%s' % (module_prefix, file), fromlist=filename)
TypeError: __import__() takes no keyword arguments

You can work around this bug (in ImportFunction.__call__) by using positional 
rather than keyword arguments.  Pass {} for globals and locals in order to get 
to fromlist.

The function doesn't verify the number of positional arguments it's passed, 
either:

Jython trunk:
>>> __import__('sys', {}, {}, [], 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
<module 'sys' (built-in)>

Python 2.5:
>>> __import__('sys', {}, {}, [], 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __import__() takes at most 5 arguments (14 given)

Thanks,

had to change my code for loading the modules to:

        # Work around for http://bugs.jython.org/issue1111
        # mod = __import__(modules, {}, {}, [ filename ], -1)
        mod = __import__(module_name)
        components = module_name.split('.')
        for comp in components[1:]:
            mod = getattr(mod, comp)

Works for 2.2.1 and 2.5a1.

BTW, from the documentation regarding __import__ I saw these notes:
Changed in version 2.5: The level parameter was added. Changed in
version 2.5: Keyword support for parameters was added.

Don't know if level is supported by jython, but just in case :)

Relative imports are near the top of my todo list (though the things
above it may take a week or two more.  I've assigned this bug to myself
to get at the same time.

Fixed in trunk r5384.  The level keyword is accepted but not yet acted upon.
