Trac: "Waiting On" plugin?

Sometimes an issue can't be re开发者_JAVA百科solved until someone else does something, or until some event occurs. Is there an add-on for trac that adds a field for these situations?

I use a needinfo keyword for such issues.

Look at AdvancedTicketWrokflowPlugin on trac-hacks. You can use set_owner_to_previous and set_status_to_previous to implement a needinfo state in your ticket workflow. In fact, a needinfo action is the example given on that page.

Have you seen the MasterTickets plugin? It adds a "blocked by" field, which is the equivalent of "waiting on". This is for dependencies between bugs, where Bug 101 can't be solved until Bug 102 is.
