directories each time it ran, at least on Windows.
Several changes: explicitly closed all files; wrapped long
lines; stopped suppressing errors when removing a file or
directory fails (removing /shouldn't/ fail!); and changed
what appeared to be incorrect usage of os.removedirs() (that
doesn't remove empty directories at and /under/ the given
path, instead it must be given an empty leaf directory and
then deletes empty directories moving /up/ the path -- could
be that the conceptually simpler shutil.rmtree() was really
actually intended here).
(http://www.cygwin.com/faq/faq_3.html#SEC41).
Also check whether onerror has actually been called so this test will
fail on assertion instead of on trying to chmod a non-existent file.
the documented behavior: the function passed to the onerror()
handler can now also be os.listdir.
[I could've sworn I checked this in, but apparently I didn't, or it
got lost???]
and test_support.run_classtests() into run_unittest()
and use it wherever possible.
Also don't use "from test.test_support import ...", but
"from test import test_support" in a few spots.
From SF patch #662807.
