Merge lp:~wallyworld/launchpad/dupe-project-warning-317258 into lp:launchpad

[Ian Booth]

Display a warning if a user wants to select a duplicate bug affecting a different project.

== Implementation ==

When a bug search is done for the bug picker, a new optional related_bug parameter is passed in. The json search results data contains a new 'different_pillars' attribute which is true if the search result bug and related bug do not have any target pillars in common.

The ui displays a warning if the bug data says that the proposed dupe and the context bug have no pillars in common.

== Demo and QA ==

http://people.canonical.com/~ianb/different-project-warning.png
http://people.canonical.com/~ianb/different-project-warning2.png

== Tests ==

Enhance bug picker and duplicate bug yui tests.
Enhance getBugData() unit tests.

== Lint ==

Checking for conflicts and issues in changed files.

[Curtis Hovey (sinzui)]

I think the code is good, as is the text. I don't think we want two warning messages to have different font weights. I don't think we need to make the message bold.

review: Approve (code)
