BackTalk to Document The Zope Book (2.6 Edition)/Maintaining Zope

A comment to the paragraph below was recently added via http://zope.org/Documentation/Books/ZopeBook/2_6Edition/MaintainingZope.stx#2-40

---------------

    If you want to automatically pack the ZODB you could tickle the
    appropriate URL with a small python script (the traditional
    filesystem based kind, not Zopes "Script (Python)")::

      #!/usr/bin/python
      import sys, urllib
      host = sys.argv[1]
      days = sys.argv[2]
      url = "%s/Control_Panel/Database/manage_pack?days:float=%s" % \
            (host, days)
      try: 
          f = urllib.urlopen(url).read()
      except IOError:
          print "Cannot open URL %s, aborting" % url
      print "Successfully packed ZODB on host %s" % host

       Is it really possible to pack anonymously through-the-web?
       Shouldn't everything in the control panel require authentication?

      % Anonymous User - Dec. 6, 2003 12:58 pm:
       I just checked with zope 2.6.2... authentication is required to tickle that URL.

      % Anonymous User - Mar. 10, 2004 6:35 am:
       http://user:password@host:port/...

       Automatically pack the ZODB with user/password 
       This works! Please change the script above, because
       the original script makes no sense.

       #!/usr/bin/python
       import sys, urllib

       host = sys.argv[1]
       days = sys.argv[2]
       user = sys.argv[3]
       pwd  = sys.argv[4]

       class MyUrlOpener(urllib.FancyURLopener):
           def prompt_user_passwd(self, host, realm):
              return (user,pwd)
           def __init__(self, *args):
              self.version = "Zope Packer"
              urllib.FancyURLopener.__init__(self, *args)

       def main():
           urllib._urlopener = MyUrlOpener()
           url = "%s/Control_Panel/Database/manage_pack?days:float=%s" % \
                  (host, days)
           try:
             f = urllib.urlopen(url).read()
           except IOError:
             print "Cannot open URL %s, aborting" % url
             print "Successfully packed ZODB on host %s" % host

       if __name__ == '__main__':
           main()
