Hi.
I already discussed this feature with Lucas Nussbaum at Debconf11. It
would be nice to have a gatherer for patch-tracker.d.o data in UDD. I
already wrote a patch for patch-tracker.d.o to export the data we could
be interested into in a JSON file. The patch is still waiting for review
and I'll ping Sean in the next days.
I also wrote patches for UDD, and I'm attaching them here. They're still
incomplete, need to be adjusted for the actual setup of UDD (which I do
not know enough), still have some FIXME for potential SQL injection.
Moreover, SQL schemas have to be fixed and the whole infrastructure for
getting JSON data from patch-tracker.d.o must be set up.
But, in the meantime, people can have a look at the code to understand
what's going on.
I'm also attaching a draft of the SQL schema (which probably still lacks
things, most notably sane indexes). A gzipped test data file (based on a
snapshot of a few days ago) can be found here:

Thanks, Gio.

+DESCRIPTION
+ patch-tracker.d.o is a web service that shows the patches that get
+ applied to the Debian packages at build time. A summary of the shown
+ data is stored and published as JSON file, so it can be included
+ in UDD.
+
+ We import such information assigning a unique integer ID to each
+ pair (package, release). Two tables are then used to store the
+ data:
+ * patch-tracker-table: keeps general information about the
+ package (name, version, release) and about the patching method
+ it uses (the series type - i.e., whether it uses quilt, dpatch
+ or other systems, including the 'native' and 'no_series' values;
+ and the number of lines added and removed outside the debian/
+ directory by the .diff.gz or .debian.tar.gz patch);
+ * patches-table: keeps information about the specific patches
+ (the package to which belongs, its name and the number of lines
+ added and removed); it will probably extended in the future to
+ store also DEP 3 metadata.
+
+CONFIGURATION:
+ path: The path of the JSON statistics from patch-tracker.d.o.
+ patch-tracker-table, patches-table: The names of the database
+ tables used to describe the packages and patches.
