commit 4b91fe2402b37104a0c599b633ed6b381f92d336
Author: Adrien Bustany <abustany gnome org>
Date: Wed Jun 2 12:57:02 2010 -0400
Steroids: Simplify update
This command changes the way updates are done using DBus FD passing.
Instead of doing first a Prepare call and then get a FD where to write
the query, the client directly passes a FD to the server, and writes the
query to it. This reduces the number of DBus roundtrips.
