The following script explains how to create Debian GNU/Linux packages for Ceph from a clone of the sources.

releasedir=/tmp/release rm -fr releasedir mkdir -p $releasedir

remove all files not under git so they are not

included in the distribution.

git clean -dxf

git describe provides a version that is

a) human readable

b) is unique for each commit

c) compares higher than any previous commit

d) contains the short hash of the commit

vers=`git describe --match "v*" | sed s/^v//`

creating the distribution tarbal requires some configure

options (otherwise parts of the source tree will be left out).

./autogen.sh ./configure --with-rocksdb --with-ocf --with-rest-bench \ --with-nss --with-debug --enable-cephfs-java \ --with-lttng --with-babeltrace

use distdir= to set the name of the top level directory of the

tarbal to match the desired version

make distdir=ceph-$vers dist

rename the tarbal to match debian conventions and extract it

mv ceph-$vers.tar.gz $releasedir/ceph_$vers.orig.tar.gz tar -C $releasedir zxf ceph_$vers.orig.tar.gz

copy the debian directory over and remove -dbg packages

because they are large and take time to build

cp -a debian $releasedir/ceph-$vers/debian cd $releasedir perl -ni -e 'print if(!(/^Package: .*-dbg$/../^$/))' ceph-$vers/debian/control perl -pi -e 's/--dbg-package.*//' ceph-$vers/debian/rules

always set the debian version to 1 which is ok because the debian

directory is included in the sources and the upstream version will

change each time it is modified.

dvers="$vers-1"

update the changelog to match the desired version

cd ceph-$vers chvers=`head -1 debian/changelog | perl -ne 's/.*\(//; s/\).*//; print'` if [ "$chvers" != "$dvers" ]; then DEBEMAIL="contact@ceph.com" dch -b -v "$dvers" "new version" fi

create the packages

a) with ccache to speed things up when building repeatedly

b) do not sign the packages

c) use half of the available processors

PATH=/usr/lib/ccache:$PATH dpkg-buildpackage -j$(($(nproc) / 2)) -uc -us

The release directory contains the source and binary packages.

The first time around, using 12 2.1Ghz processors:

• disk space: ~200MB
• time: ~20 minutes

The second time around (i.e. ccache retrieves the results of the previous compilation)

• disk space: ~200MB
• time: ~10 minutes

Building after ccache -C and with the -dbg packages:

• disk space: ~840MB
• time: ~25 minutes

About 5 minutes is spent on compressing the 2GB of he ceph-test-dbg package.
