PI52578: USING -NONE IN A DYNAMIC VIEW CONFIG_SPEC UNDER UNIX DOES NOT HIDE THE SELECTION

APAR status

• Closed as Permanent restriction.

Error description

• The config spec rule "element <scope> <rule> -none" is ignored
  in a Unix dynamic view. The
  element is still visible when doing regular 'ls'
  
  The expected result for an element is:
  unix ls : not visible
  cleartool ls : <no version selected>
  
  The same rules under Microsoft Windows is returning the expected
  result:
  dir : not visible
  cleartool ls : <no version selected>

  * PROBLEM DESCRIPTION:                                         *
  * The "ls" command lists the contents of a directory (i.e.,    *
  * the names it contains) and the config spec rule doesn't      *
  * apply to that directory, just some sub-directory/file, so    *
  * returning the contents of the directory element is correct   *
  * behavior.  When trying to use one of the names in the        *
  * directory, the config spec rule comes into play for that     *
  * name, so you can't stat it or read it, which, again, is      *
  * correct behavior.  If you want to not see the name(s) in a   *
  * directory element, you have to do "cleartool rmname" to get  *
  * rid of it...just like any other file system (where you can   *
  * read a dir contents and get a name that then might return an *
  * error if you use it if you don't have sufficient access to   *
  * the object named).                                           *

Problem conclusion

• The problem on Unix/Linux...using the config spec rule -none
  hides the element, but the name of the element is still in its
  containing directory.  Therefore, using a Unix/Linux /bin/ls
  command will show the name, since the user has access to the
  containing directory and /bin/ls just lists names.  However, if
  you try to get stat information about the "hidden" element, for
  instance by using "/bin/ls -l", the stat will fail (since the
  element is hidden) and, from my experiments, every platform
  handles that situation slightly differently, although AIX and
  HPUX seem to be the same.  For instance, I used a config spec
  rule of "element /vobs/atria/uts/fs -none" and then did "cd
  /vobs/atria/uts" and did a "/bin/ls -l" with these results:
  
  AIX and HPUX:
      []: /bin/ls -l
      ./fs not found
      total 6
      drwxrwxr-x 1 atria ccdev 22 Jun 05 2014 .
      drwxrwx--- 32 atria ccdev 2290 Jul 28 2014 ..
  
  Solaris 10:
      []: /bin/ls -l

      drwxrwx--- 32 atria ccdev 2290 Jul 28 2014 ..
  
  SLES 10:
      []: /bin/ls -l
      /bin/ls: fs: No such file or directory

  RHEL 5.10:
      []: /bin/ls -l
      total 3
      drwxrwxr-x 1 atria ccdev 22 Jun 5 2014 .
      drwxrwx--- 32 atria ccdev 2290 Jul 28 2014 ..
      ?--------- ? ? ? ? ? fs
  
  RHEL 6.7:
      []: /bin/ls -l
      ls: cannot access fs: No such file or directory
      total 3
      drwxrwxr-x. 1 atria ccdev 22 Jun 5 2014 .
      drwxrwx---. 32 atria ccdev 2290 Jul 28 2014 ..
      ??????????? ? ? ? ? ? fs
  
  Note, Solaris 10 actually does what we are after, but the others
  include error messages or a line for the name (with no
  attributes), or both.
