Flaw in ticket assignee list

[Emmanuel Blot]

I just bumped into an issue which looks like a regression (since the upgrade to Trac trunk from 0.10.3, using r4665):

The drop-down list used to assign an owner to a ticket is not filled as (I) expected. Only a few names among all the users registered on the system appear in the drop-down list.

The drop-down list content is built from the list of users that own the TICKET_MODIFY permission.

When the TICKET_MODIFY permission is only set for the special authenticated user, it seems that the list is not populated - w/ the exception of the users that own 'parent' permissions, for example the list of the administrators as TRAC_ADMIN permission leads to grant TICKET_MODIFY permission.

Many others have already been authenticated on the system:

select * from session where authenticated=='1';

reports 34 users.

Additional comment from cboos:

This is likely a regression introduced by [4625]

Confirmed by #5328.

Increasing the priority, as this should be fixed for 0.11

#5616 marked as another duplicate

If either cmlenz or athomas could have a look… Thanks!

#5689 looks like another duplicate.

FYI, I have users in 'poweruser' group, which has TRAC_ADMIN right. They are listed in the drop down. But other authenticated users with TRAC_MODIFY are not.

cboos is right, this is a regression from [4625]. The problem is that the optimized code did not take 'authenticated' into account.

Fixed using a brute-force inefficient solution in [5849], and I will reopen #4245.
