Live branches

Show branch content within the main web application, rather than sequestered on bazaar.l.n

Moving parts:

• loggerhead serves machine-readable branch content (files, diffs, revision metadata, etc)
• same-origin proxy that republishes this through code.launchpad.net (probably in Apache)
• javascript updates to show content within the page
• branch page redesign to make it work well

New things to show on the branch page:

• per-revision lists of changed file
• per-revision diffs
• files in the tip of the branch
• more than the 10 most recent revisions

Issues:

• republished information must be safe against xss-type attacks from user content

Specific work items:

• return JSON from loggerhead (currently returns HTML snippets)
• in Launchpad add javascript (i.e. client-side) templating/rendering of that JSON content. Use hidden HTML node in page, copy and populate with values from JSON, add new node to page.

• proxy data from loggerhead through on https://code.launchpad.net/
