This plugin is meant to help you with your agile process using Trac. One of the key practices of agile development, is prioritizing the backlog. That can be difficult to do in Trac, as it doesn't have any way of doing fine-grained ranking of tickets. This plugin helps resolve that short-coming.
TracBacklog adds a new navigational element to your navigation bar. Clicking on it will take you to the unscheduled backlog (all active tickets that aren't currently assigned to a milestone). On the right hand side, is a listing of open milestones. The idea is that you drag-n-drop tickets within the list itself to change their rank. Once you're happy with the ranking (i.e., you've worked with your customer to prioritize the outstanding tickets), you drag-n-drop tickets onto a milestone to assign it into the milestone. This effectively treats milestones as sprints, which works well for us... and I hope it works well for you!
The unscheduled backlog is created from tickets that are not assigned to any milestone. You can also view each milestone and see and individual backlog for it, but all tickets are ranked absolutely (they maintain their absolute ranking when you drag them in and out of a milestone). Furthermore, if you are trying this on an existing project, the initial rank for each ticket will be it's ticket id. You'll want to spend some time sorting your tickets, and you may want to consider pulling them all into the unscheduled backlog when you do that (so that you can order the all the tickets against each other).
It requires simplejson 2.0 or better, and Trac 0.11 or better.
$ easy_install -U TracBacklog
From a tarball:
python setup.py install
Enable the plugin in trac.ini:
[components] backlog.* = enabled
Users can customize the fields they see in the Backlog preference pane.
Also, you will need to run trac-admin upgrade on your database, since the plugin needs to create a table and some default values for your tickets.
