Sometimes we make a Fedora release in which translations crash anaconda,
and that sucks, and I'd like us not to do that. I have the beginnings of
an idea of how not to do that and I'd like some feedback.
We have a handful of tests against translations in anaconda, but it's
not just anaconda that's translated. Given that errors in translations
in any library used by anaconda can crash anaconda, I feel that it's
important to test the translations in all of the code we maintain to
make sure that mistakes from translators aren't going to make anything
blow up.
The transifex/zanata model is nice in that the code repository isn't
crudded up with constant translation commits, but its biggest pitfall is
that translations, and mistakes in translations, can be changed right up
until the moment we create a release tarball. For that reason I'd like
the tests to be run both as part of the jenkins CI and just before a
release is built. The input would be the source tarball: the output of
make dist for anaconda, make archive for blivet, etc.
This would not be as simple as moving tests/gettext/ into its own repo
and adding a script or two. Most of the tests in tests/gettext/ test
translatable strings rather than translated strings, and tests against
translatable strings are mostly anaconda-specific.
The tests I would like to move out of anaconda and run against every
project are:
- gettext/gettext_warnings.sh, which mostly catches busted format
strings (including errors on our end where the string needs named
parameters)
- the translation portion of glade/check_markup.py
(I could go either on this, since it should really only be
anaconda that has markup strings, but I think it should at least be
something that is run at package build time)
- a new test in reaction to 1283599 in which the translator screwed
up the Plural-Forms header in lt.po in blivet.
Which leave these staying behind:
- click.py, which ensures "clickable" anaconda info bars have
something to click
- contexts.py, which ensures that strings with keyboard accelerators
have a translation context. Stuff from outside anaconda shouldn't be
adding keyboard accelerators
- gettext_potfiles.py, which ensures we keep POTFILES.in up to date.
anaconda is the only one using autotools so the only one with a POTFILES.in
- style_guide.py, which checks that we say "host name" instead of
"hostname" and stuff like that. I dunno, maybe every project should get
that treatment? Argue your case.
Discussion question: should this stuff go in a for-real package in
Fedora? The pros would be easier release-time testing (could be an
automatic part of rc-release or similar), integration with make ci, and
Chris wouldn't need to configure any new stuff in jenkins. Cons would be
that there's another package in Fedora and that testing translations in
make ci would be adding yet more things out of our control.
As far as how all of this looks, I was thinking just a directory of
checkers (maybe convert gettext_warnings.sh to python for consistency)
and a script that runs them all. I suppose how the script finds the
checkers depends on how real of a program we want it to be, whether it
would need an argument to the directory or could just search via python
imports.
