This document describes the processes for making and announcing a Bazaar
5
release, and managing the release process. This is just one phase of the
6
`overall development cycle <cycle.html>`_, but it's the most complex part.
7
This document gives a checklist you can follow from start to end in one
12
Preparing the tree for release
13
------------------------------
15
.. Was previously at http://bazaar-vcs.org/ReleaseChecklist
17
#. Make a local branch for preparing this release. (Only for the first
18
release in a series, otherwise you should already have a branch.) ::
20
bzr branch trunk prepare-1.6
22
#. Configure pqm-submit for this branch, with a section like this in
23
``~/.bazaar/locations.conf``::
25
[/home/mbp/bzr/prepare-1.4]
26
pqm_email = Canonical PQM <pqm@bazaar-vcs.org>
27
submit_branch = http://bazaar-vcs.org/bzr/bzr.1.4
28
submit_to = bazaar@lists.canonical.com
30
#. In the release branch, update ``version_info`` in
31
``./bzrlib/__init__.py``. Check the output of ``bzr --version``.
33
#. Add the date and release number to ``./NEWS``
35
#. Summarize into one or two paragraphs what's new in this release.
37
#. Commit these changes to the release branch, using a command like::
39
bzr commit -m "Release 0.12rc1."
41
The diff before you commit will be something like::
43
=== modified file 'NEWS'
44
--- NEWS 2008-09-17 23:09:18 +0000
45
+++ NEWS 2008-09-23 16:14:54 +0000
53
+This release includes many bug fixes and a few performance and feature
54
+improvements. ``bzr rm`` will now scan for missing files and remove them,
55
+like how ``bzr add`` scans for unknown files and adds them. A bit more
56
+polish has been applied to the stacking code. The b-tree indexing code has
57
+been brought in, with an eye on using it in a future repository format.
58
+There are only minor installer changes since bzr-1.7rc2.

# Python version 2.0 is (2, 0, 0, 'final', 0)." Additionally we use a
69
# releaselevel of 'dev' for unreleased under-development code.
71
-version_info = (1, 7, 0, 'candidate', 2)
72
+version_info = (1, 7, 0, 'final', 0)
75
# API compatibility version: bzrlib is currently API compatible with 1.7.
78
#. Submit those changes to PQM for merge into the appropriate release
82
bzr pqm-submit -m "(mbp) prepare 1.6"
84
#. When PQM succeeds, pull down the master release branch.
87
Making the source tarball
88
-------------------------
90
#. Change into the source directory and run ::
94
This also makes a zip file, which is easier to access on Microsoft
97
#. Now we'll try expanding this tarball and running the test suite
98
to check for packaging problems::
100
make check-dist-tarball
103
Publishing the release
104
----------------------
106
Now you have the releasable product. The next step is making it
107
available to the world.
109
#. In <https://launchpad.net/bzr/> click the "Release series" for this
110
series, to take you to e.g. <https://launchpad.net/bzr/1.1>. Then
111
click "Register a release", and add information about this release.
113
#. Within that release, upload the source tarball and zipfile and the GPG
114
signature. Or, if you prefer, use the
115
``tools/packaging/lp-upload-release`` script to do this.
117
#. Link from http://bazaar-vcs.org/Download to the tarball and signature.
119
#. Announce on the `Bazaar home page <http://bazaar-vcs.org/>`_.
121
#. Check that the documentation for this release is available in
122
<http://doc.bazaar-vcs.org>. It should be automatically build when the
123
branch is created, by a cron script ``update-bzr-docs`` on
127
Announcing the release
128
----------------------
130
Now that the release is publicly available, tell people about it.
132
#. Make an announcement mail.
134
For release candidates, this is sent to the ``bazaar-announce`` and
135
``bazaar`` lists. For final releases, it should also be cc'd to
136
``info-gnu@gnu.org``, ``python-announce-list@python.org``,
137
``bug-directory@gnu.org``. In both cases, it is good to set
138
``Reply-To: bazaar@lists.canonical.com``, so that people who reply to
139
the announcement don't spam other lists.
141
The announce mail will look something like this:
143
| Subject: bzr x.yy released!
145
| <<Summary paragraph from news>>
147
| Thanks to everyone who contributed patches, suggestions, and
150
| bzr x.yy is now available for download from
151
| http://bazaar-vcs.org/Download as a source tarball; packages
152
| for various systems will be available soon.
154
| <<NEWS section from this release back to the last major release>>
156
#. Make an announcement through <https://launchpad.net/bzr/+announce>
158
#. Update the IRC channel topic. Use the ``/topic`` command to do this,
159
ensuring the new topic text keeps the project name, web site link, etc.
161
#. Announce on http://freshmeat.net/projects/bzr/
163
This should be done for both release candidates and final releases. If
164
you do not have a Freshmeat account yet, ask one of the existing
167
#. Update http://en.wikipedia.org/wiki/Bzr -- this should be done for
168
final releases but not for Release Candidates.
170
#. Update the python package index: <http://pypi.python.org/pypi/bzr> - best
173
python setup.py register
175
Remember to check the results afterwards.
177
To be able to register the release you must create an account on
178
<http://pypi.python.org/pypi> and have one of the existing owners of
179
the project add you to the group.
182
Merging the released code back to trunk
183
---------------------------------------
185
Merge the release branch back into the trunk. Check that changes in NEWS
186
were merged into the right sections. If it's not already done, advance
187
the version number in ``bzr`` and ``bzrlib/__init__.py``. Submit this
188
back into pqm for bzr.dev.
194
* `Packaging into the bzr PPA <ppa.html>`_ to make and publish Ubuntu
196
* `Bazaar Developer Document Catalog <index.html>`_
197
* `Development cycles <cycle.html>`_: things that happen during the cycle
198
before the actual release.
