Apache::Htgroup - Manage Apache authentication group files


  use Apache::Htgroup;
  $htgroup = Apache::Htgroup->load($path_to_groupfile);
  &do_something if $htgroup->ismember($user, $group);
  $htgroup->adduser($user, $group);
  $htgroup->deleteuser($user, $group);


Manage Apache htgroup files

Please note that this is not a mod_perl module. Please also note that there is another module that does similar things (HTTPD::UserManage) and that this is a more simplistic module, not doing all the things that one does.


The following methods are provided by this module.


    $htgroup = Apache::Htgroup->load($path_to_groupfile);

Returns an Apache::Htgroup object.


    $htgroup = Apache::Htgroup->new();
    $htgroup = Apache::Htgroup->new( $path_to_groupfile );

Creates a new, empty group file. If the specified file already exists, loads the contents of that file. If no filename is specified, you can create a group file in memory, and save it later.


    $htgroup->adduser( $username, $group );

Adds the specified user to the specified group.


    $htgroup->deleteuser($user, $group);

Removes the specified user from the group.


    $groups = $htgroup->groups;

Returns a (reference to a) hash of the groups. The key is the name of the group. Each value is a hashref, the keys of which are the group members. I suppose there may be some variety of members method in the future, if anyone thinks that would be useful.

It is expected that this method will not be called directly, and it is provided as a convenience only.

Please see the section below about internals for an example of the data structure.



If you have not already called save(), you can call reload() and get back to the state of the object as it was loaded from the original file.



Writes the current contents of the htgroup object back to the file. If you provide a $file argument, save will attempt to write to that location.


    $foo = $htgroup->ismember($user, $group);

Returns true if the username is in the group, false otherwise


Although this was not the case in earlier versions, the internal data structure of the object looks something like the following:

 $obj = { groupfile => '/path/to/groupfile',
          groups => { group1 => { 'user1' => 1,
                                  'user2' => 1, 
                                  'user3' => 1
                      group2 => { 'usera' => 1,
                                  'userb' => 1, 
                                  'userc' => 1

Note that this data structure is subject to change in the future, and is provided mostly so that I can remember what the heck I was thinking when I next have to look at this code.

Adding groups

A number of folks have asked for a method to add a new group. This is unnecessary. To add a new group, just start adding users to a new group, and the new group will magically spring into existance.

     Revision 1.9  2001/11/10 20:53:44  rbowen
     Moved Htgroup to lib subdir. Appropriate changesin MANIFEST,
     Makefile.PL. Updated README.

     Revision 1.19  2001/11/10 20:45:15  rbowen
     Moved it to the lib subdirectory, and added some code folds. No
     functional code change.
     Revision 1.18  2001/08/02 02:47:23  rbowen
     Added LICENSE.
     Revision 1.17  2001/07/12 02:37:18  rbowen
     Patch from Ben Tilly in order to compensate for the fact that Apache
     does not like group lists that run over 8k, but is ok with breaking a
     group listing over several lines. Long lines are split over several
     Revision 1.16  2001/07/12 02:19:58  rbowen
     Doc changes. Regenerated README. Removed since there's a
     decent test suite.
     Revision 1.15  2001/07/12 02:15:01  rbowen
     Revision 1.14  2001/02/24 21:27:50  rbowen
     Added space between "group:" and the first user, as per the documentation.
     Revision 1.13  2001/02/23 04:13:12  rbowen
     Apparently Perl 5.005_02 was getting grumpy about my use of Revision
     to set the VERSION number. Fixed.
     Revision 1.12  2001/02/23 03:16:58  rbowen
     Fixed bug in reload that was effectively breaking everything else.
     It would let you build files from scratch, but not load existing
     files correctly. Added test suite also, which should help
     Revision 1.11  2001/02/21 03:14:04  rbowen
     Fixed reload to work as advertised. groups now calls reload internally
     the first time you call it.
     Version 0.9 -> 1.10 contains a number of important changes.
     As mentioned above, the API has changed, as well as the internal
     data structure. Please read the documentation very carefully.
