[New-bugs-announce] [issue26658] test_os fails when run on Windows ramdisk

[Jeremy Kloth]

New submission from Jeremy Kloth:

The Win32JunctionTests class fails when the test suite is run on an ImDisk[1]_ virtual disk.  The junctions are created successfully, however os.stat() fails on them (winerror 123).  os.lstat() does succeed.

I'm inclined to believe that this is a bug in the ImDisk device driver, but when testDown() is run, it fails to remove the newly created junction to the test directory.  By leaving the junction in place, when the test runner completes it removes the entire temporary test directory containing the junction thus removing the Lib test directory!

I suggest that at least changing the tearDown() method to use os.path.lexists() to ensure that the junction is removed regardless of its target existing or not.
