Allow check_permission to work with TICKET_VIEW_* permissions

[Norman Rasmussen]

I would like to use this to restrict certain workflow items to the ticket's OWNER only, see #3567 as an example.

This plugin is already a standard permission policy. If it doesn't work, the problem is in how the workflow system checks permissions.

Sorry, I don't think you understand, here's the rule I'm trying to set up in the workflow system:

accept.permissions = TICKET_VIEW_OWNER

I'm trying to limit accept to the current owner of the ticket. (without forcing set_owner_to_self)

As far as I can see the plugin return None for 'TICKET_VIEW_OWNER'. It's only designed to grant 'TICKET_VIEW' if the user has 'TICKET_VIEW_OWNER' and is the owner - I want 'TICKET_VIEW_OWNER' to be granted if the user is the owner.

I don't want to assign the user 'TICKET_VIEW_OWNER' because then they will only be able to see their own tickets. I actually want something like TICKET_IS_OWNER.

I will look at making a patch first, then give some more feedback.

This sounds fine, but isn't related to privatetickets. The place to implement such a selector is in a workflow plugin.

VirtualTicketPermissionsPlugin now handles this.
