Thanks for the clarification, Anil, I didn't realize the difference between roles and permissions.

I agree.  I think we should leave as is.

There may be confusion about the model in place:
*  specific permissions are checked on actions
*  roles are defined as sets of permissions
*  users are assigned roles
I think this is pretty conventional, and I think there's value in keeping with that.

Personally I would leave as is.  Having multiple roles/authorities per
action, is kind of useful if you want to extend roller.  The overhead is
also minimal compared with what struts does internally.

Does anyone else on the team have a view? #5 below I'm no longer sure on
so I'm withdrawing that proposal but feedback on #1-#4 below is most

I don't see the need for this change and I would leave those permissions
in
place. They existed to support and may still be used to support real uses cases like private blogging, where only registered users can see blogs and
only those with special permissions can comment.

Even if they do not work fully now, they give people a way to hook their own rules into their own custom versions of Roller, perhaps by adding new code, ServletFilters, etc. And they are a starting point for people who
want private blogging to be fully supported in Roller.

  OK, checking Global Permission, we have these three levels:
      /** Allowed to login and edit profile */
      public static final String LOGIN  = "login";

      /** Allowed to login and do weblogging */
      public static final String WEBLOG = "weblog";

/** Allowed to login and do everything, including site-wide admin */
      public static final String ADMIN  = "admin";

We don't use "weblog" though, we save it as "editor" in the userrole
table. We also don't use "login" for anything other than to make it the minimum required setting on pages that don't require an ADMIN setting.
All
newly registered users are given "editor" as a minimum, meaning we could raise minimum from "login" to "editor" and do away with the login role
without any difference in application behavior.

On top of this, we allow the roles additional subroles per the
roller.properties file:

# Role name to global permission action mappings
role.names=editor,admin
role.action.editor=login,comment,weblog
role.action.admin=login,comment,weblog,admin

"comment" is also never used in the application, further, in the above list we're inconsistently assigning admin to admin but weblog to editor.
   Since the permissions are all Russian doll (login < comment <
weblog/editor < admin), it's sufficient to just store the highest role,
as
the lower ones are all implied, i.e., we don't need these properties.

My proposal is to:

1.) Replace the above LOGIN/WEBLOG/ADMIN strings with a two-value
enumeration, EDITOR and ADMIN. Later, if we have user demand for LOGIN
and
COMMENT, and somebody actually coding in logic that uses those values, we can easily add in the enumerations for them. (I don't like LOGIN much,
however, if we don't trust them not to blog they shouldn't be lurking
around the UI.)

2.) The "userrole" database table will be dropped, replaced with a new varchar column ROLE in the Roller_User table. I'll update the migration
script to copy the user's highest role into that column.

3.) The three properties "role.name, role.action.editor, and
role.action.admin" will be removed.

4.) List<String> requiredGlobalPermissionActions() will return a single
enumeration constant instead (EDITOR or ADMIN), stating the minimum
accepted value.

5.) WeblogPermissions looks fine, except I'll just switch the string
array
of EDIT_DRAFT, ADMIN, POST, to an enumeration constant with the same
values
and have requiredWeblogPermissionActions() return an enumeration
constant
instead.

How does this sound?  I have other things to work on so I'll wait 72
hours
before proceeding to give time for others to evaluate this change.

Glen

If the methods return just a single permission instead of a collection
of
permissions, at least for GlobalPermissionActions, that means we can
move
to "Russian doll" type role levels, where each permission level includes all the permission levels below it (de facto the way Roller runs now).
If
we can officially be on that, that means we can toss out the userrole
table
and just place a single column "rolename" (indicating the highest role a
person has) in the roller_user table, a very sleek change.  (I'm not
talking about Roller_Permission, i.e., permissions a user has on each
blog
-- that table is still needed, but the userrole table indicating whether
one's a global admin or not.)

I don't have a strong opinion, but this seems like change just for the

especially when compared to all the database calls that are made during
JSP

Hi team, one or both of these methods are heavily called within the

application, indeed for almost every action run:

       public List<String> requiredWeblogPermissionActions() {
return Collections.singletonList(WeblogPermission.xxxxx);
       }

       public List<String> requiredGlobalPermissionActions() {
return Collections.singletonList(GlobalPermission.xxxxxx);
       }

I've checked every implementation of both methods within the
application
-- about 20-25 in all -- every one returns just a single permission
requirement, not a list of items.

I think it would be good to optimize these methods by having them
return
just a string or a fast and lightweight enumeration constant. The only
thing lost I can see would be the ability to require multiple
permissions,
but again within the app today and through 12-14 years of Roller it
just
hasn't been needed.  WDYT?

Glen
