[Fofredux-devel] big, possibly painful, change

[Kevin <ke...@dr...>]

In the process of fixing bug #1499270,  I fundamentally changed how 
unique items are handled by the update logic and database.   There is a 
new column on the item table named 'hash'.   The value is an SHA1 hash 
of the items link, title, and contents.  The column is indexed for fast 
searching.  This should eliminate the performance problems with feed 
updates on a database with many items items.  (greater then 20K)

Let me know if anyone finds a case where this logic is flawed.
