Hi

I'm planning to add rev_parent_id column to revision table in order to put revisions in a tree structure (using the Adjacency List Model). This field is the key to rev_id in the same table. I've made corrections to several files (take a look at http://svn.wikimedia.org/viewvc/mediawiki/branches/roman/trunk/phase3/mainte...). I need this patch for incremental diff (and blamemaps) however it could be also used for example to render history as a tree (think slashdot discussion). Please cc your reply to my email: rnosov at gmail dot com

Best regards Roman
