This document describes the processes for making and announcing a Bazaar
5
release, and managing the release process.
7
See also: `Bazaar Developer Document Catalog <index.html>`_.
16
To start a new release cycle:
18
#. Send mail to the list with the key dates, who will be the release
19
manager, and the main themes or targetted bugs. Ask people to nominate
20
objectives, or point out any high-risk things that are best done early,
21
or that interact with other changes.
23
#. Add a new "series" in Launchpad at <https://launchpad.net/bzr/+addseries>. There is one
24
series for every *x.y* release.
30
TODO: Things to cover:
32
* Early communication to downstream teams (e.g. Launchpad) about changes in dependencies.
33
* Reminder re lifecycle and where we're up to right now
34
* Summary of recent successes and pending work
35
* Reminder re release objectives
36
* Reminder re things needing attention, e.g. bug triage, reviews, testing of certain things, etc.
42
TODO: Get material from http://bazaar-vcs.org/FeatureFreeze.
46
Preparing the tree for release
47
------------------------------
49
.. Was previously at http://bazaar-vcs.org/ReleaseChecklist
51
.. TODO: Still needs more clarity on what's in a RC versus a final
54
This is the procedure for making a new bzr release:
56
#. If the release is the first candidate, make a new branch in PQM.
57
(Contact Robert Collins for this step).
59
Register the branch at https://launchpad.net/products/bzr/+addbranch
61
#. Run the automatic test suite and any non-automated tests. (For example, try a download over http; these should eventually be scripted though not automatically run.). Try to have all optional dependencies installed so that there are no tests skipped. Also make sure that you have the c extensions compiled (``make`` or ``python setup.py build_ext -i``).
63
#. In the release branch, update ``version_info`` in ``./bzrlib/__init__.py``
65
#. Add the date and release number to ``./NEWS``, and a one-paragraph
66
summary of changes in this release.
68
#. Commit these changes to the release branch, using a command like::
70
bzr commit -m "(jam) Release 0.12rc1."
72
The diff before you commit will be something like::
74
=== modified file 'NEWS'
75
--- NEWS 2006-10-23 13:11:17 +0000
76
+++ NEWS 2006-10-23 22:50:50 +0000
79
+bzr 0.12rc1 2006-10-23
84
=== modified file 'bzrlib/__init__.py'
85
--- bzrlib/__init__.py 2006-10-16 01:47:43 +0000
86
+++ bzrlib/__init__.py 2006-10-23 22:49:46 +0000
88
# Python version 2.0 is (2, 0, 0, 'final', 0)." Additionally we use a
89
# releaselevel of 'dev' for unreleased under-development code.
91
-version_info = (0, 12, 0, 'dev', 0)
92
+version_info = (0, 12, 0, 'candidate', 1)
94
if version_info[3] == 'final':
95
version_string = '%d.%d.%d' % version_info[:3]
97
#. Submit those changes to PQM for merge into the appropriate release
100
#. When PQM succeeds, pull down the master release branch.
102
Making the source tarball
103
-------------------------
105
#. Change into the source directory and run ::
109
#. Now we'll try expanding this tarball and running the test suite
110
to check for packaging problems::
112
make check-dist-tarball
115
Publishing the release
116
----------------------
118
Now you have the releasable product. The next step is making it
119
available to the world.
121
#. In <https://launchpad.net/bzr/> click the "Release series" for this
122
series, to take you to e.g. <https://launchpad.net/bzr/1.1>. Then
123
click "Register a release", and add information about this release.
125
#. Within that release, upload the source tarball and the GPG signature.
127
#. Link from http://bazaar-vcs.org/Download to the tarball and signature.
129
#. Update http://doc.bazaar-vcs.org/ to have a directory of documentation
130
for this release. (Controlled by the ``update-bzr-docs`` script on
131
escudero, and also update the ``latest`` symlink in
132
``/srv/bazaar.canonical.com/doc/``.)
134
#. Announce on the `Bazaar home page`__
136
__ http://bazaar-vcs.org/
139
Announcing the release
140
----------------------
142
Now that the release is publicly available, tell people about it.
144
#. Announce to ``bazaar-announce`` and ``bazaar`` mailing lists.
145
The announce mail will look something like this:
147
| Subject: bzr 0.11 release candidate 1
149
| INTRO HERE. Mention the release number and date, and why the release. (i.e. release candidate for testing, final release of a version, backport/bugfix etc).
152
| http://bazaar-vcs.org/releases/src/bzr-VERSION.tar.gz
154
| http://bazaar-vcs.org/releases/src/bzr-VERSION.tar.gz.sig
156
| DESCRIBE-CHANGES-IN-OVERVIEW-HERE
158
| DESCRIBE-when the next release will be (if there is another - i.e. this is a release candidate)
160
| Many thanks to all the contributors to this release! I've included the
161
| contents of NEWS for VERSION below:
163
To generate the data from NEWS, just copy and paste the relevant news section and clean it up as appropriate. The main clean-up task is to confirm that all major changes are indeed covered. This can be done by running ``bzr log`` back to the point when the branch was opened and cross checking the changes against the NEWS entries.
165
(RC announcements should remind plugin maintainers to update their plugins.)
167
* For point releases (i.e. a release candidate, or an incremental fix
168
to a released version) take everything in the relevant NEWS section. For
169
example, for 0.11rc2 take everything in NEWS from the bzr 0.11rc2 line to the bzr 0.11rc1 line further down.
171
* For major releases (i.e. 0.11, 0.12 etc), take all the combined NEWS sections from within that version: for 0.11 take all of the 0.11 specific section, plus 0.11rc2, plus 0.11rc1 etc.
173
#. 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.
175
#. Announce on http://freshmeat.net/projects/bzr/
177
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.
179
#. Update http://en.wikipedia.org/wiki/Bzr -- this should be done for final releases but not Release Candidates.
181
#. Package maintainers should update packages when they see the
186
#. Post to http://mail.python.org/mailman/listinfo/python-announce-list for major releases
188
#. Update the python package index: <http://pypi.python.org/pypi/bzr> - best
191
python setup.py register
193
Remember to check the results afterwards.
195
To be able to register the release you must create an account on
196
<http://pypi.python.org/pypi> and have one of the existing owners of
197
the project add you to the group.
200
Merging the released code back to trunk
201
---------------------------------------
203
Merge the release branch back into the trunk. Check that changes in NEWS
204
were merged into the right sections. If it's not already done, advance
205
the version number in ``bzr`` and ``bzrlib/__init__.py``. Submit this
206
back into pqm for bzr.dev.
209
Updating the PPA for a new release
210
----------------------------------
212
We build Ubuntu ``.deb`` packages for Bazaar as an important part of the release
213
process. These packages are hosted in a `Personal Package Archive (PPA)`__ on
214
Launchpad, at <https://launchpad.net/~bzr/+archive>.
216
__ https://help.launchpad.net/PPAQuickStart
218
We build packages for every supported Ubuntu release
219
<https://wiki.ubuntu.com/Releases>. Packages need no longer be updated
220
when the release passes end-of-life because all users should
223
The ``debian/`` directory containing the packaging information is kept in
224
branches on Launchpad, named like
225
<https://code.launchpad.net/~bzr/bzr/packaging-hardy>.
227
Preconditions for building these packages:
229
* You must have a Launchpad account and be a member of the `~bzr`__ team
231
__ https://edge.launchpad.net/~bzr/+members>
233
* You must have a GPG key registered to your Launchpad account.
235
* Configure ``dput`` to upload to our PPA with this section in your
239
fqdn = ppa.launchpad.net
241
incoming = ~bzr/ubuntu
243
allow_unsigned_uploads = 0
245
* You need a Ubuntu (or probably Debian) machine, and ::
247
sudo apt-get install build-essential devscripts dput quilt patch
249
Here is the process; there are some steps which should be automated in
252
#. You will need a working directory for each supported release, such as
253
``~/bzr/Packaging/hardy``
255
#. Download the official tarball of the release to e.g. ``~/bzr/Releases``
257
#. Copy the original tarball into your per-disto directory, then untar it
258
and if necessary rename it::
260
cp -l ~/bzr/Releases/bzr-1.3.tar.gz bzr_1.3.orig.tar.gz
261
tar xfvz bzr_1.3.orig.tar.gz
264
#. Change into that directory and check out the packaging branch::
268
bzr+ssh://bazaar.launchpad.net/~bzr/bzr/packaging-hardy \
271
#. For Bazaar plugins, change the ``debian/control`` file to express a
272
dependency on the correct version of ``bzr``.
274
For bzrtools this is typically::
276
Build-Depends-Indep: bzr (>= 1.3~), rsync
277
Depends: ${python:Depends}, bzr (>= 1.3~), bzr (<< 1.4~), patch
279
#. Make a new ``debian/changelog`` entry for the new release,
280
either by using ``dch`` or just editing the file::
282
dch -v '1.3-1~bazaar1' -D hardy
284
dch will default to the distro you're working in and this isn't checked
285
against the version number (which is just our conversion), so make sure
288
**Caution:** Release candidates must insert a tilde to make them sort
289
before the final release, like this: ``bzr-1.4~rc2-1~bazaar1``.
291
Make sure you have the correct email address for yourself, version
292
number, and distribution. It should look something like this::
294
bzr (1.3-1~bazaar1) hardy; urgency=low
296
* New upstream release.
298

300
If you need to upload the package again to fix a problem, normally you
301
should increment the last number in the version number, following the
302
distro name. Make sure not to omit the initial ``-1``, and make sure
303
that the distro name in the version is consistent with the target name
304
outside the parenthesis.
306
#. Commit these changes into the packaging branch::
308
bzr ci -m '1.3-1~bazaar1: New upstream release.' debian
310
#. Build a source package::
314
This will create a ``.changes`` file in the per-distro directory,
315
and should invoke gpg to sign it with your key.
316
Check that file is reasonable: it should be uploading to the intended
317
distribution, have a .orig file included, and the right version number.
319
#. Upload into the PPA::
321
dput bzr-ppa ../bzr__1.3-1\~bazaar1\_source.changes
323
Don't forget the ``bzr-ppa`` component or dput will try to upload into
324
the main archive by default. You can disable this by adding this
325
section to your ``.dput.cf``::
328
fqdn = SPECIFY.A.PPA.NAME
330
#. Copy the uploaded package over to other Ubuntu releases, taking advantage
331
of Launchpad's Copy Package feature <https://launchpad.net/~bzr/+archive/+copy-packages>
333
**Caution:** Make sure the dependencies are the same between Ubuntu releases,
334
Dapper has different dependencies, but others might change in time.
335
If you upload a release-specific version, you should add a ~release1 to
336
the package version, for example:: bzr.1.3-1~bazaar1~dapper1
338
#. You should soon get an "upload accepted" mail from Launchpad, which
339
means that your package is waiting to be built. You can then track its
340
progress in <https://launchpad.net/~bzr/+archive> and
341
<https://launchpad.net/~bzr/+archive/+builds>.
343
If you add all the bzr PPAs to your ``sources.list`` then you can see a
344
summary of current package versions with::
346
apt-cache madison bzr
