Optional component which makes it possible to easily add new permissions to a Trac environment. These can be used for example in configurable TracWorkflows, when one wants to add a permission specific to a transition, via the .permissions key.
To add new permissions, create a new section [extra-permissions] in trac.ini. Every entry in that section defines a meta-permission and a comma-separated list of permissions. For example:
[extra-permissions] extra_admin = extra_view, extra_modify, extra_delete
This entry will define three new permissions EXTRA_VIEW, EXTRA_MODIFY and EXTRA_DELETE, as well as a meta-permission EXTRA_ADMIN that grants all three permissions.
If you don't want a meta-permission, start the meta-name with an underscore (_):
[extra-permissions] _perms = extra_view, extra_modify
