Lucas Nussbaum recently posted some graphics showing the number of packages that are grabbed from Debian and kept untouched, modified, out of sync, etc, etc.

But, "statistics are tricky":


$ wget http://patches.ubuntu.com/p/php5/php5_5.2.6-1ubuntu3.patch

$ lsdiff -i '*out' php5_5.2.6-1ubuntu3.patch | wc -l
44



I believe people familiar with test suites know what that means...

Update: it means that the test suite files (outputs, expected results, and so on) are on the .diff.gz, thus contaminating it

Oh, and:


$ out=$(mktemp); filterdiff -i '*tests*' php5_5.2.6-1ubuntu3.patch > $out
$ du -h php5_5.2.6-1ubuntu3.patch $out
436K php5_5.2.6-1ubuntu3.patch
372K /tmp/tmp.eAxRv20298


...what a waste of space

Another advantage of using the vcs-$VCS fieldcheckbashisms as a perl module fun

I'm sorry, I'm not familiar enough with these packages to understand what you're trying to get at; could you spell out the implications of the information you show please?
