illegal link suceeds (Posix)

[agroce]

import shutil
import pyfakefs.fake_filesystem
import os

ROOT_PATH = "/Volumes/ramdisk/test"

fs = pyfakefs.fake_filesystem.FakeFilesystem()
fs.CreateDirectory('/Volumes')
fs.CreateDirectory('/Volumes/ramdisk')
fs.CreateDirectory('/Volumes/ramdisk/test')
os0 = pyfakefs.fake_filesystem.FakeOsModule(fs)
opener0 = pyfakefs.fake_filesystem.FakeFileOpen(fs)

if False:
    os0 = os
    shutil.rmtree(ROOT_PATH)
    os.mkdir(ROOT_PATH)
    opener0 = open

component0 = "alpha" 
component1 = "" 
path0 = ROOT_PATH 
path1 = ROOT_PATH 
path0 += os.path.sep + component0 
component0 = "beta" 
path0 += os.path.sep + component1 
path1 += os.path.sep + component0 
file0 = opener0(path1,'w') 
os0.link(path1,path0) 

OS raises OSError: [Errno 2] No such file or directory

Correctly raises no error under Windows, raises no error under Posix instead of OSError 2.

If I leave out:

• symlinks
• rename
• tell
• nlinks
• getsize

Then things look very good on the latest version, no failures so far in testing. In the big regression set, it actually went backwards from 400+ failures to 1000+, but it looks like these are all to do with symlinks, maybe.

symlinks - sigh...
