test-docker-packaging: test packages built using docker
For now this only tests debian packages, but it could easily be
extended to also test rpms.
#require test-repo slow docker
$ OUTPUTDIR=`pwd`
$ export OUTPUTDIR
$ cd "$TESTDIR"/..
$ make docker-debian-jessie > $OUTPUTDIR/build.log 2>&1
$ cd $OUTPUTDIR
$ ls *.deb
mercurial-*.deb (glob)
We check debian package contents with portable tools so that when
we're on non-debian machines we can still test the packages that are
built using docker.
$ ar x mercurial*.deb
$ tar tf data.tar* | grep localrepo | sort
./usr/lib/python2.7/site-packages/mercurial/localrepo.py
./usr/lib/python2.7/site-packages/mercurial/localrepo.pyc
$ rm -f *.deb build.log
