Misc news on the QA infrastructure
The PTS gained package descriptions and other changes to help increase
its usefulness for more folks. The watch file upload web interface
(called rolex and written by Vasudev Kamath) was deployed to help make it
easier to help fixing watch files. The PTS gained links to archives of
the mailing lists used by Debian teams for commonly used list servers and
to the dedup (see below), clang and screenshots services. More work on
the semantic aspects of the PTS was done, a new wnpp site was setup and
DEP-12 about upstream metadata was setup. These items are discussed in
more detail below.
The Debian QA infrastructure always needs more folks working on it, so if
you have some spare time, please check out the code and come join us on
the debian-qa mailing list and IRC channel.
Shrinking the archive with dedup.debian.net
A manual or binary placed twice in a package can needlessly grow a
package without anyone noticing. Many such cases are easy opportunities
to shrink binary packages by replacing one copy with a link to the other.
dedup.debian.net lists files shared between packages and summarizes
the potential gain. Being a diagnostics tool it also lists e.g.
duplication of copyright files, so unless the gain is significant looking
into details is likely not worth the effort.
It can also be used to discover embedded copies. It therefore also looks
at gzip decompressed contents and decompressed PNG image data where
applicable. That way it can find compressed GPL copies for example. This
tool is very much work in progress, so ideas for improvement and other
kind of feedback are very much welcome.
The service is linked from the PTS for packages with large amounts of
duplicate files and there are tips for reducing duplication available.

DEP 12 started
The Debian Enhancement Proposal number 12 (DEP 12), for per-package
machine-readable metadata about Upstream, was started. It will specify
the syntax of the debian/upstream file in source packages. Discussion
takes place on the debian-qa mailing list.

implemented in, the UI toolkit they use, or the field of
