heads up: MO files are disappearing in Juno

[Tom Fifield]

Hi,

This is just a heads up from upstream that the compiled message catalogues (MO files) for translations previously bundled with horizon will be removed for the Juno release. PO files will remain.

MO files are effectively binary files easily generated from the PO files per language, using gettext. A script has also been provided for conveniences (run_tests.sh --compilemessages) - but direct use of gettext is also fairly straightforward.

Other distributions, including debian upstream, are compiling these messages as part of their packaging

To ensure that your users continue to be able to use translations in openstack-dashboard, it might be worth checking if you rely on the upstream MO files, and if you do, generating them in-package instead.

Something like this also works:
cd horizon && django-admin compilemessages && cd ..
cd openstack_dashboard && django-admin compilemessages && cd ..
# remove unnecessary .po files
find . -name "django*.po" -exec rm -f '{}' \;

Horizon developer doc will cover the installation step including how to compile message catalogs.

The detail instruction is available in the horizon developer documentation since Oct 2014
(after https://review.openstack.org/#/c/126169/ was merged).

One year passed from then. I think we can close the bug.
