I'm seeing a lot of general cases where one bug can't be worked on or completed until another is fixed. In many cases, this problem is nested where several bugs must be cleared before a particular target bug can be worked on. For planning purposes, it would be extremely useful to have a "depends on" field where we could list the bugs that must be fixed before this bug can be fixed. Having them in a separate field would allow people to do useful queries such as "bugs with no dependencies", "bugs with dependencies", or "all bugs depending on bug xxxx". An interesting co-feature would be to automatically bump the priority of prerequisite bugs when a dependent bug is higher priority (although I don't know if that would be politically acceptable around here :-)

OK, done! Dependency stuff is now in bugzilla. Though I haven't done the priority munging stuff; it doesn't feel right to me. And I haven't yet added the ability to query by dependency; I'm still thinking about what the right thing to do is.

Verif. See also bug #16743 for dealing with the priority issue. Query by dependency is a part of the recently added advanced querying, although currently broken on bug #30823.
