Issue1110

when I try to install lastest version django on lastest jython version, 
get "couldn't make directories". It seems ntpath.isdir failed.

This is a bug/"feature" in the MSVCRT stat function, which Jython uses through jna-
posix.

#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>

int main(void) {
  struct stat foo;
  int retval = stat("c:\\Documents and Settings\\", &foo);
  fprintf(stderr, "stat returned %d\n", retval);
  perror("stat");
}

% ./stat
stat returned -1
stat: No such file or directory

If you remove the trailing \, it works fine.

I think this problem still exists in 2.5alpha3

Here is my workarounds

in lib\os.py:

def makedirs(path, mode='ignored'):
    """makedirs(path [, mode=0777])

    Super-mkdir; create a leaf directory and all intermediate ones.

    Works like mkdir, except that any intermediate path segment (not
    just the rightmost) will be created if it does not exist.
    The optional parameter is currently ignored.
    """
    sys_path = sys.getPath(path)
    if File(sys_path).mkdirs():
        return
    if(sys_path[-1]=='\\'):
        if File(sys_path[:-2]).mkdirs():
            return

    # if making a /x/y/z/., java.io.File#mkdirs inexplicably fails. So 
we need
    # to force it
    
    # need to use _path instead of path, because param is hiding
    # os.path module in namespace!
    head, tail = _path.split(sys_path)
    if tail == curdir:
        if File(_path.join(head)).mkdirs():
            return
        if(_path.join(head)[-1]=='\\'):
            if File(_path.join(head)[:-2]).mkdirs():
                return
                
    raise OSError(0, "couldn't make directories", path)

This issue still exists in 2.5b1; I am experiencing the issue when
trying to install Django on jython.

I am attaching a patch to install_egg_info.py which solves the problem
on my Windows machine.

Fix implemented in revision 6164.
