[Merge] lp:~jtv/launchpad/recife-kill-updatetranslation-browser into lp:~launchpad/launchpad/recife

 

Jeroen T. Vermeulen has proposed merging lp:~jtv/launchpad/recife-kill-updatetranslation-browser into lp:~launchpad/launchpad/recife with lp:~jtv/launchpad/recife-pre-killUpdateTranslation-browser as a prerequisite.

Requested reviews:
  Launchpad code reviewers (launchpad-reviewers): code


= Getting Rid of updateTranslation, Part II: Browser Code =

This eliminates updateTranslation from the browser code responsible for accepting and saving translations entered in the web UI.  It's for the Recife feature branch.  It moves the entire family of views over to the new data model, and partly the last remaining unmigrated view as well.  updateTranslation is a behemoth of such complexity and intelligence that we had to replace it rather than try to maintain it.

I didn't try to get it all done in this branch, or it would get too big.  Unfortunately that means that I had to disable one test and hobble another: having one leg in the old data model and one in the new is bound to break some tests.  I created a kanban card for re-activating the disabled test—the other one we'll find back automatically as it will break once it becomes ready to move over.

A very pedestrian-looking part of the migration is where we replace getCurrentTranslationMessage calls with getCurrentTranslation ones.  The latter is suited for the new model, whereas the former is a holdout from the old world.  I also use a traits class here and there that abstracts the difference between the two "translation sides": Ubuntu translations and upstream translations.  In the Recife model, a single TranslationMessage can be shared between Ubuntu and a project so it may be current on either side, or both, or neither.  The traits allow code to ask things like "does this TranslationMessage have the flag set that designates it as the current translation for this side?"—without having to care which of the flags for which of the two sides that is.

The browser method with The Big Change is _storeTranslations.  I extracted some methods to reduce cyclomatic complexity and increase testability.  That makes the replacement for updateTranslation look simpler than perhaps it is.  Still, simplicity is a good thing!

You'll notice one case where the POTemplate passed to getCurrentTranslation is None.  That's because a TM's potemplate is not there to tell us exactly which potemplate it belongs to (normally it can be shared between any number of templates) but rather whether it is diverged to a specific potemplate (and if so of course, which one).  So passing None means "I'm not interested in diverged messages; give me only the shared ones i.e. the ones with potemplate set to None."

I also made the getCurrentTranslationMessageOrDummy side-sensitive.  It always used to look for the current translation message on the Ubuntu side, which is not very helpful in the new model.  Now it looks for the current translation message on whatever side the given POFile is on.

The only good way to test this is to run the full Translations test suite.  We'll Q/A it with the rest of the feature branch.  There's a bit of pre-existing lint left, but only of a kind where I'm not confident that the linter is right: complaints about the number of blank lines between methods when there is a free-floating comment that needs a blank line on top and another below.
