Translation Templates from Branch

This is an attempt to guide you through a manual test of the nascent mechanism to produce translation templates based on a bzr branch.

It still needs lots of work.

Enabling local branch access

mkdir -p /var/tmp/bazaar.launchpad.dev/static
mkdir -p /var/tmp/ppa

There's a bug somewhere in Windmill that may break access to local branches through http.

To see if this is biting you, look in your Apache error log (/var/log/apache2/error.log) for a traceback ending with something like this (your home directory and the version numbers will vary):

  File "/home/me/canonical/lp-sourcedeps/eggs/windmill-1.3beta3_lp_r1440-py2.5.egg/windmill/dep/_mozrunner/global_settings.py", line 42, in <module>
    def findInPath(fileName, path=os.environ['PATH']):
  File "/usr/lib/python2.5/UserDict.py", line 22, in __getitem__
    raise KeyError(key)
KeyError: 'PATH'

Near the top of the traceback you'll find mention of a Launchpad branch, probably canonical/lp-branches/devel or canonical/lp-branches/trunk. From that branch, remove two imports:

• From lib/lp/testing/__init__.py remove this import:

from windmill.authoring import WindmillTestClient

• From lib/canonical/testing/layers.py remove this:

from windmill.bin.admin_lib import (
    start_windmill, teardown as windmill_teardown)

Now restart Apache.

Getting branch updates noticed

• Create a Launchpad source tree, and cd into it.
• Substituting your email address, run (parts may fail, but it's probably okay):

utilities/start-dev-soyuz.sh
utilities/soyuz-sampledata-setup.py -e <your@email.address>
make run_codehosting >/dev/null 2>&1 &

• Open launchpad.dev in browser, log in as <your@email.address>, with password "test"

• Create project "bf-test" for ppa-user at https://launchpad.dev/projects/+new

• Register hosted branch "bf-test" for trunk at https://code.launchpad.dev/bf-test/trunk/+addbranch

• Link branch to trunk at https://launchpad.dev/bf-test/trunk/+linkbranch

• Enable translations for project at https://launchpad.dev/bf-test/+edit

• Enable template imports for trunk at https://translations.launchpad.dev/bf-test/trunk/+translations-settings

• Create branch. Just paste into a terminal (you may be prompted for your GPG passphrase):

    pushd /tmp
    bzr init bf-test
    cd bf-test
    cat <<EOF >test.c
#include <gettext-po.h>
#include <stdio.h>
main(){puts(_("Hi"));}
EOF
    mkdir po
    echo test.c >po/POTFILES.in
    bzr add test.c
    bzr add po
    bzr add po/POTFILES.in
    bzr commit -m "Setting up fake intltool branch."
    bzr push lp://dev/bf-test --remember --use-existing-dir
    popd

• Back in your branch: make sync_branches

Now you should have a TranslationTemplatesBuildJob sitting in the BranchJob table. You should see a very wide line of data coming out of:

psql launchpad_dev -c '
    select *
    from branchjob
    join job on job.id=branchjob.job
    join buildqueue on buildqueue.job=job.id
    where branchjob.job_type=6'

Preparing the slave

Follow the instructions for setting up a local buildd slave at BuildFarm/TryOutBuildSlave. Skip the part where it tells you to run Launchpad, since you're already running it.

Unfortunately the branch_url parameter you see in the json_data will not work on a dev system. So we have to hack it up a bit:

psql launchpad_dev -c "
    update branchjob
    set json_data = '{\"branch_url\": \"http://code.launchpad.dev/bf-test\"}'
    where
        branchjob.job_type=6 and
        json_data like '%http://bazaar.launchpad.dev/~ppa-user/bf-test/bf-test%'"

XXX: Actually that won't work either because the slave doesn't know about code.launchpad.dev. Have to get bazaar.launchpad.dev working.
