======================
  Ceph Release Process
======================

1. Build environment
====================

There are multiple build envrionments, debian based packages are built via pbuilder for multiple distributions.  The build hosts are listed in the ``deb_hosts`` file, and the list of distributions are in ``deb_dist``.  All distributions are build on each of the build hosts.  Currently there is 1 64 bit and 1 32 bit build host.

The RPM based packages are built natively, so one distribution per build host.  The list of hosts is found in ``rpm_hosts``.

Prior to building, it's necessary to update the pbuilder seed tarballs::

    ./update_all_pbuilders.sh

2. Setup keyring for signing packages
=====================================

::

    export GNUPGHOME=<path to keyring dir>

    # verify it's accessible
    gpg --list-keys

The release key should be present::

  pub   4096R/17ED316D 2012-05-20
  uid   Ceph Release Key <sage@newdream.net>


3. Set up build area
====================

Clone the ceph and ceph-build source trees::

    git clone http://github.com/ceph/ceph.git
    git clone http://github.com/ceph/ceph-build.git

In the ceph source directory, checkout next branch (for point releases use the {codename} branch)::

    git checkout next

Checkout the submodules::

    git submodule update --init

4.  Update Build version numbers
================================

Substitute the ceph release number where indicated below by the string ``0.xx``.

Edit configure.ac and update the version number. Example diff::

	-AC_INIT([ceph], [0.54], [ceph-devel@vger.kernel.org])
	+AC_INIT([ceph], [0.55], [ceph-devel@vger.kernel.org])
 
Update the version number in the debian change log::

	DEBEMAIL user@host dch -v 0.xx-1

Commit the changes::

	git commit -a

Tag the release::

	../ceph-build/tag-release v0.xx


5. Create Makefiles
===================

The actual configure options used to build packages are in the
``ceph.spec.in`` and ``debian/rules`` files.  At this point we just
need to create a Makefile.::

	./do_autogen.sh


6. Run the release scripts
==========================

This creates tarballs and copies them, with other needed files to
the build hosts listed in deb_hosts and rpm_hosts, runs a local build
script, then rsyncs the results back tot the specified release directory.::

	../ceph-build/do_release.sh /tmp/release


7. Create RPM Repo
==================

Copy the rpms to the destination repo

       mkdir /tmp/rpm-repo
       ../ceph-build/push_to_rpm_repo.sh /tmp/release /tmp/rpm-repo 0.xx

Next add any additional rpms to the repo that are needed such as leveldb and
and ceph-deploy.  See RPM Backports section

Finally, sign the rpms and build the repo indexes

  ../ceph-build/sign_and_index_rpm_repo.sh /tmp/release /tmp/rpm-repo 0.xx


8. Create Debian repo
=====================

The key-id used below is the id of the ceph release key from step 2::

	mkdir /tmp/debian-repo
	../ceph-build/gen_reprepro_conf.sh /tmp/debian-repo key-id
	../ceph-build/push_to_deb_repo.sh /tmp/release /tmp/debian-repo 0.xx main


Next add any addition debian packages that are needed such as leveldb and
ceph-deploy.  See the Debian Backports section below.

Debian packages are signed when added to the repo, so no furthur action is
needed.


9.  Push repos to ceph.org
==========================

For a development release::

	rcp ceph-0.xx.tar.bz2 ceph-0.xx.tar.gz \
	     ceph_site@ceph.com:ceph.com/downloads/.
	rsync -av /tmp/rpm-repo/0.xx/ ceph_site@ceph.com:ceph.com/rpm-testing
	rsync -av /tmp/debian-repo/ ceph_site@ceph.com:ceph.com/debian-testing

For a stable release, replace {CODENAME} with the release codename (e.g., ``argonaut`` or ``bobtail``)::

        rcp ceph-0.xx.tar.bz2 \
            ceph_site@ceph.com:ceph.com/downloads/ceph-0.xx.tar.bz2
        rcp ceph-0.xx.tar.gz  \
            ceph_site@ceph.com:ceph.com/downloads/ceph-0.xx.tar.gz
        rsync -av /tmp/rpm-repo/0.xx/ ceph_site@ceph.com:ceph.com/rpm-{CODENAME}
        rsync -auv /tmp/debian-repo/ ceph_site@ceph.com:ceph.com/debian-{CODENAME}

10. Update Git
==============

Point release
-------------

For point releases just push the version number update to the
branch and the new tag:

    git push origin {codename}
    git push origin v0.xx

Development and Stable releases
-------------------------------

For a development release, update tags for ``ceph.git``::

    git push origin v0.xx
    git push origin HEAD:last
    git checkout master
    git merge next
    git push origin master
    git push origin HEAD:next

Similarly, for a development release, for both ``teuthology.git`` and ``ceph-qa-suite.git``::

    git checkout master
    git reset --hard origin/master
    git branch -f last origin/next
    git push -f origin last
    git push -f origin master:next

Stable release
--------------

Also, for ``ceph.git``:

Just push the new tag::

	git push origin v0.xx
