===================
  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 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
====================

Checkout ceph and ceph-build::

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

Checkout next branch::

    git checkout next

Checkout the submodules (only needed to prevent errors in recursive make)::

    git submodule update --init

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

Edit configure.ac and change version number::

    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, creates the yum repository
rpm and indexes.::

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

8. Create debian repo
=====================

::

    mkdir /tmp/debian-repo
    mkdir /tmp/debian-repo/conf
    ../ceph-build/gen_reprepro_conf.sh debian-testing main \
		 `cat ceph-build/deb_dists`
    ../ceph-build/push_to_deb_repo.sh /tmp/release /tmp/debian-repo main

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

For a development release::

    rsync -av /tmp/repo/0.52/ 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``)::

    rsync -av /tmp/repo/0.52/ ceph_site@ceph.com:ceph.com/rpm-{CODENAME}
    rsync -auv /tmp/debian-repo/ ceph_site@ceph.com:ceph.com/debian-{CODENAME}

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

Development release
-------------------

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

    git push origin HEAD:testing
    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 testing origin/next
    git push -f origin testing
    git push -f master:next

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

For ``ceph.git``:

    git push origin stable
