Releasing Bazaar
================
This document describes the processes for making and announcing a Bazaar
release, and managing the release process. This is just one phase of the
`overall development cycle <cycle.html>`_, but it's the most complex part.
This document gives a checklist you can follow from start to end in one
go.
.. contents::
Preparing the tree for release
------------------------------
.. Was previously at http://bazaar-vcs.org/ReleaseChecklist
#. Make a local branch for preparing this release. (Only for the first
release in a series, otherwise you should already have a branch.) ::
bzr branch trunk prepare-1.14
#. Download the pqm plugin and install it into your ``~/.bazaar/plugins``::
bzr branch lp:bzr-pqm ~/.bazaar/plugins/pqm
#. Configure pqm-submit for this branch, with a section like this in
``~/.bazaar/locations.conf``::
[/home/mbp/bzr/prepare-1.14]
pqm_email = Canonical PQM <pqm@bazaar-vcs.org>
submit_branch = http://bazaar-vcs.org/bzr/bzr.1.14
public_branch = http://bazaar.your-domain.com/bzr
submit_to = bazaar@lists.canonical.com
smtp_server = mail.your-domain.com:25
Please see <http://doc.bazaar-vcs.org/latest/developers/HACKING.html#an-overview-of-pqm>
for more details on PQM
#. In the release branch, update ``version_info`` in ``./bzrlib/__init__.py``.
Double check that ./bzr ``_script_version`` matches ``version_info``. Check
the output of ``bzr --version``.
#. Add the date and release number to ``./NEWS``
#. To check that all bugs mentioned in ``./NEWS`` are actually marked as
closed in Launchpad, you can run ``tools/check-newsbugs.py``::
./tools/check-newsbugs.py NEWS
#. Summarize into one or two paragraphs what's new in this release.
#. Commit these changes to the release branch, using a command like::
bzr commit -m "Release 1.14."
The diff before you commit will be something like::
=== modified file 'NEWS'
--- NEWS 2008-09-17 23:09:18 +0000

+bzr 1.7 2008-09-23
+------------------
+
+This release includes many bug fixes and a few performance and feature
+improvements. ``bzr rm`` will now scan for missing files and remove them,
+like how ``bzr add`` scans for unknown files and adds them. A bit more
+polish has been applied to the stacking code. The b-tree indexing code has
+been brought in, with an eye on using it in a future repository format.
+There are only minor installer changes since bzr-1.7rc2.

# Python version 2.0 is (2, 0, 0, 'final', 0)." Additionally we use a
# releaselevel of 'dev' for unreleased under-development code.

+version_info = (1, 7, 0, 'final', 0)
# API compatibility version: bzrlib is currently API compatible with 1.7.
#. Tag the new release::
bzr tag bzr-1.14
#. Push those changes to a bzr reposistory that is public and accessible on
the Internet. PQM will pull from this repository when it attempts to merge
your changes. Then submit those changes to PQM for merge into the
appropriate release branch::
bzr push
bzr pqm-submit -m "(mbp) prepare 1.14"
#. When PQM succeeds, pull down the master release branch.
Making the source tarball
-------------------------
#. Change into the source directory and run ::
make dist
This also makes a zip file, which is easier to access on Microsoft
Windows.
#. Now we'll try expanding this tarball and running the test suite
to check for packaging problems::
make check-dist-tarball
Publishing the release
----------------------
Now you have the releasable product. The next step is making it
available to the world.
#. In <https://launchpad.net/bzr/> click the "Release series" for this
series, to take you to e.g. <https://launchpad.net/bzr/1.14>. Then
click "Register a release", and add information about this release.
#. Within that release, upload the source tarball and zipfile and the GPG
signature. Or, if you prefer, use the
``tools/packaging/lp-upload-release`` script to do this.
#. Link from http://bazaar-vcs.org/Download to the tarball and signature.
#. Announce on the `Bazaar home page <http://bazaar-vcs.org/>`_.
#. Check that the documentation for this release is available in
<http://doc.bazaar-vcs.org>. It should be automatically build when the
branch is created, by a cron script ``update-bzr-docs`` on
``escudero``.
Announcing the release
----------------------
Now that the release is publicly available, tell people about it.
#. Make an announcement mail.
For release candidates, this is sent to the ``bazaar-announce`` and
``bazaar`` lists. For final releases, it should also be cc'd to
``info-gnu@gnu.org``, ``python-announce-list@python.org``,
``bug-directory@gnu.org``. In both cases, it is good to set
``Reply-To: bazaar@lists.canonical.com``, so that people who reply to
the announcement don't spam other lists.
The announce mail will look something like this::
Subject: bzr x.yy released!
<<Summary paragraph from news>>
The Bazaar team is happy to announce availability of a new
release of the bzr adaptive version control system.
Bazaar is part of the GNU system <http://gnu.org/>.
Thanks to everyone who contributed patches, suggestions, and
feedback.
Bazaar is now available for download from
http://bazaar-vcs.org/Download as a source tarball; packages
for various systems will be available soon.
<<NEWS section from this release back to the last major release>>
Feel free to tweak this to your taste.
#. Make an announcement through <https://launchpad.net/bzr/+announce>
#. Update the IRC channel topic. Use the ``/topic`` command to do this,
ensuring the new topic text keeps the project name, web site link, etc.
#. Announce on http://freshmeat.net/projects/bzr/
This should be done for both release candidates and final releases. If
you do not have a Freshmeat account yet, ask one of the existing
admins.
#. Update `<http://en.wikipedia.org/wiki/Bazaar_(software)>`_ -- this should be done
for final releases but not for Release Candidates.
#. Update the python package index: <http://pypi.python.org/pypi/bzr> - best
done by running ::
python setup.py register
Remember to check the results afterwards.
To be able to register the release you must create an account on
<http://pypi.python.org/pypi> and have one of the existing owners of
the project add you to the group.
Merging the released code back to trunk
---------------------------------------
Merge the release branch back into the trunk. Check that changes in NEWS
were merged into the right sections. If it's not already done, advance
the version number in ``bzr`` and ``bzrlib/__init__.py``. Submit this
back into pqm for bzr.dev.
You should also merge (not pull) the release branch into
``lp:~bzr/bzr/current``, so that branch contains the current released code
at any time.
