You're absolutely correct, which is why I think the current set up is
already the best we can have:
- Automatic imports
- Automatic exports (exporting to a separate branch).
Sorry I didn't include the info about the exports layout on my previous
reply. It was meant to be a generic list of advantages of manual vs.
automatic exports, and what I meant by that point is that in automatic
ones the files are named correctly (e.g. <languagecode>.po) and are
placed in the right location, which is something that often does not
happen with manual exports.
Now in the particular case of Ubuntu docs we've got the following layout:
But Launchpad expects the common gettext layout, i.e. flat, with all .po
files and .pot file in one same folder:
Which in turn means the ubuntu-docs layout is not directly supported. I
only realised that after I had initially suggested to use automatic
exports to trunk, so I apologise for suggesting a non-working option. I
think it would still work if we were to set symlinks linking to the
right paths, but unless someone would like to volunteer for
investigating this approach, I'd suggest leaving trunk exports for now.
In summary, though, I'd still recommend the current setup (automatic
imports, automatic exports to separate branch) for this and future releases.

It still offers advantages.
Compare (manual export):
1. Go to the docs project Launchpad URL
2. Request the full translations download (only project maintainers can
3. Wait for Launchpad to request (it might take from minutes, to hours
to days, depending on Launchpad's load)
4. Check your e-mail, retrieve the download link
5. Fetch translations from the download link, wait for download to complete
6. Uncompress tarball, fix filenames and paths if necessary
7. Put translations in the ubuntu-docs tree
8. Commit translations:
bzr commit -m"Updated translations from Launchpad"
Vs (automatic export to separate branch):
1. Checkout latest translations:
bzr checkout --lightweight
2. Put the translations in the ubuntu-docs tree. E.g. (where PODIR is
the checkout location of the previous command, and DOCSDIR where the
ubuntu-docs tree lives)
for f in "$PODIR/ubuntu-help/"*.po
LANG=`basename $f .po`
echo "Copying $f to $DOCSDIR/ubuntu-help/$LANG"
cp $f $DOCSDIR/ubuntu-help/$LANG
3. Commit translations:
bzr commit -m"Updated translations from Launchpad"
The second option (automatic export to separate branch) you can do in a
matter of a few minutes in a synchronous manner, while the first option
might take hours and you'll be depending on Launchpad and you'll have to
finish your work asynchronously.

I'm not a bzr expert either, so I'm not in the position to provide an
authoritative answer. In any case, I'll just add a few points to the
- With the 3-step approach above, you would not be merging revisions
with bzr, simply copying the files from the latest revision and adding a
commit. In that case, the size concern would not apply.
- I'm not sure how translation commits affect history in terms of size,
be it from merging an external branch or from having daily commits to
trunk. Note that daily commits only add .po files which have had
modifications in Launchpad since the last commit, so in days where no
one translates in Launchpad, you'd have no daily commit. The same if
e.g. only Italian translators do work: you'd then only have a commit for
it.po. Also note that this is similar with the GNOME approach:
translations are committed to trunk directly (with the difference that
it's translators who do the commits, instead of Launchpad).

I can automate the whole process without manual intervention, basically
scripting the 3 steps outlined above.
In fact, I already do it and that's how I update translations on
http://126.96.36.199/ (btw, back online) daily. The only thing that's
missing is for me to set up a cron job to run once a day, which I'll do
whenever I've got some time.
