Get Rid of Role Folders

1 Requirements

Role folders are used as container for local roles.
Due to performance reasons I suggest to get rid of these role folders (except the role folder for global roles in the administration).
The following services would benefit from this removal:

• reduces the tree entries
• better performance for membership queries - one table join less - which are used in the calendar, courses, groups, session...
• better performance for every access check, since the tree query for role folders can be cut down.

4 Discussion

JF 12 May 2014: We appreciate this improvement and schedule it for 4.5.

5 Implementation

Stefan Meyer , 4 Nov 2014: This feature has been implemented for ILIAS 5.0.

• Maintainers of repository plugins with auto generated roles should check their code if it relies on the existance of role folders. The new method ilObjRole::createDefaultRole() should be used for the creation of default roles.
