We build a distinct package for each distrorelease.
27
We build packages for every supported Ubuntu release
28
<https://wiki.ubuntu.com/Releases>. Packages need no longer be updated
29
when the release passes end-of-life because all users should
30
have upgraded by then. (As of May 2008, Edgy Eft is no longer supported.)
32
We build a distinct package for each distrorelease. As of bzr 1.5, Dapper
33
uses ``python-support`` and later distributions use ``python-central``.
32
34
If you upload a release-specific version, you should add a suffix to the
33
35
package version, e.g. ``bzr.1.3-1~bazaar1~dapper1``.
35
Dapper uses the ``python-support`` framework and later distributions use
36
``python-central``. This has little effect on everyday packaging but does
37
mean that some of the control files are quite different.
39
37
Every package is first uploaded into the beta ppa. For final release
40
38
versions it is also copied to the main PPA.
42
40
The packaging information is kept in branches of bzr on Launchpad, named
44
<https://code.launchpad.net/~bzr/ubuntu/hardy/bzr/bzr-ppa>.
42
<https://code.launchpad.net/~bzr/bzr/packaging-hardy>.
46
<lp:~bzr/ubuntu/hardy/bzr/bzr-ppa>. These branches are intended to be used
44
<lp:~bzr/bzr/packaging-hardy>. These branches are intended to be used
47
45
with the ``bzr-builddeb`` plugin.
49
**You should almost always upload to the beta ppa first** and then either
50
upload again or copy the packages into the release ppa. That reduces the
51
risk of breaking the main archive from which people get bzr updates.
57
We build packages for every supported Ubuntu release
58
<https://wiki.ubuntu.com/Releases>. Packages need no longer be updated
59
when the release passes end-of-life because all users should
60
have upgraded by then.
62
As of August 2010, the following releases are supported:
67
* Jaunty (support ends October 2010)
69
* Dapper LTS (supported but no longer updated for new releases)
71
The ``rmadison bzr`` command will gives you an up-to-date summary
72
of which bzr releases are current in each Ubuntu release.
80
53
* You must have a GPG key registered to your Launchpad account.
82
On reasonably recent versions of Ubuntu you no longer need special dput
83
configuration, because you can just say ::
85
dput ppa:bzr/proposed <source.changes
88
However, you may still want to add these lines to ``~/.dput.cf`` prevent
89
inadvertently attempting to upload into Ubuntu or Debian, which will
90
give a somewhat unclear error::
55
* Configure ``dput`` to upload to our PPA with this section in your

fqdn = ppa.launchpad.net

allow_unsigned_uploads = 0

incoming = ~bzr/ubuntu

You may also want to add these lines to prevent inadvertently attempting
73
to upload into Ubuntu or Debian, which will give a somewhat unclear

Overview of packaging with builddeb
120
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
122
* First update the oldest supported branch, using ``bzr merge-upstream``.
124
* Run ``bzr builddeb -S -- -sa`` to build a source package, then put
127
(``-S`` says to make a source-only upload, which is
128
required for Launchpad's builders. ``--sa`` says to include the
129
``.orig.tgz`` even if this doesn't seem to be the first upload for an
130
upstream release: this is often needed when rebuilding something that's
131
previously been uploaded to Debian or Ubuntu or into a different PPA.)
133
* Now merge across that change into each supported branch with a
134
simple ``bzr merge``.
136
Locally testing using pbuilder
137
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
139
It may be useful to locally test builds inside pbuilder. You may want to
140
use the script from <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=255165>
141
to wrap it, and to give it sensible defaults for your local machine.
143
Update all packages in proposed before copping the main ppa
144
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
146
If one updates bzr, and there are plugins that are not compatible with the
147
new version of bzr, this can cause pain for users using the ppa. In order to
148
avoid this, we first get all packages up to date in the proposed ppa, and then
149
copy them to the main ppa.
160

export PACKAGE="bzr"

Rinse and repeat for all the plugins by changing VERSION and PACKAGE.

dput bzr-ppa ../bzr_1.17-1\~bazaar1\~hardy1\_source.changes

Alternatively, you can use Launchpad's "copy" feature to copy the
243
packages between repositories.
292
245
#. You should soon get an "upload accepted" mail from Launchpad, which
293
246
means that your package is waiting to be built. You can then track its

summary of current package versions with::

Testing the contents of the PPA
335
-------------------------------
337
A somewhat crude but useful way to test the contents of the PPA is to
338
install the relevant packages into an schroot::
340
schroot -c hardy-test -u root -- \
341
apt-get install -o 'APT::Install-Suggests="true"' \
342
-o 'APT::Install-Recommends="true"' \
345
This should make sure everything can be installed; it won't guarantee that

Packaging dependencies

----------------------
351
Some of our updates to bzr in previous releases require backports of our
352
dependencies. Specific branches holding these backports:
