Subject: bug in rmdir(2)
Date: Wed, 28 Sep 2005 20:31:53 +0000
Message-Id: <092820052031.26647.433AFDB9000034B50000681722073000330A050E040D0C079D0A@comcast.net>

POSIX requires resolving a filename with a trailing slash as
though . were implicitly present, and requires rmdir(2) to fail
with EINVAL if the final component is '.'.  Therefore, both of
these cases should fail rather than removing the directory:

$ mkdir a b
$ rmdir a/ b/.
$ ls a b      # Oops, rmdir("a/") and rmdir("b/.") incorrectly succeeded
ls: a: No such file or directory
ls: b: No such file or directory
