Q A
Branch? 6.1
Bug fix? no
New feature? yes
Deprecations? no
Tickets Fix #44414
License MIT
Doc PR symfony/symfony-docs#...

This PR is a proposal for #44414.

When pulling translations from Loco, we save the Last-Modified response header in each MessageCatalogue thanks to the new CatalogueMetadataAwareInterface.

When pulling translations one more time from Loco, we send the previous Last-Modified response header as If-Modified-Since request header if it's available.
If Loco returns a 304, we don't update current translations. If it's not the case, we keep the original behaviour.

Catalogue metadata can be used to store metadata about the catalogue itself and not about translations.
Actually, only .xliff format is supported (read/write).

WDYT?

Thanks!

I had to add declarations prop-group/prop, otherwise it breaks because we have some validations on XLIFF files.

I'm not sure to understand why PHPUnit tests are failing:

Symfony\Component\DependencyInjection\Exception\InvalidArgumentException: Invalid definition for service "translation.provider_factory.loco": "Symfony\Component\Translation\Bridge\Loco\LocoProviderFactory::__construct()" requires 5 arguments, 4 passed

The file src/Symfony/Bundle/FrameworkBundle/Resources/config/translation_providers.php has been updated and service reference translator have been added as 5th argument to translation.provider_factory.loco service, but it fails.

Do someknow what's going on here? Thanks!

Hey!

I think @rvanlaak has recently worked with this code. Maybe they can help review this?

Cheers!

Here are some little comments.
I guess we need to update the changelog of Translation component, because this PR add support of prop-group and prop XLIFF tags?

WDYT @stof @nicolas-grekas?

Thanks for your comments :)

We still have the issue when running tests, and this issue only happens in CI:

Symfony\Component\DependencyInjection\Exception\InvalidArgumentException: Invalid definition for service "translation.provider_factory.loco": "Symfony\Component\Translation\Bridge\Loco\LocoProviderFactory::__construct()" requires 5 arguments, 4 passed

ping @nicolas-grekas @stof, do you know what can happens here? Thanks!

Looks great already. Do you have an idea whether the other translation providers also support the If-Modified-Since header?

Code is ok for me, but we will need @nicolas-grekas or @stof help to fix the failing test, I have difficulties to understand what is wrong here

Adding BC layers for the added constructor parameters should help fixing the failing tests, at least the high-deps one.
For low-deps, we may need to bump the symfony/translation requirement in Loco Bridge's composer.json to ^6.1 to make it always has the new interfaces.

New constructor parameters should be mentioned in CHANGELOG/UPGRADE files also

Thanks for your comments @chalasr, the symfony/translation dependency bump was the key! :)

The failures are unrelated IMO.

I guess the full test case can be removed?

I think it would be nice to ensure the LocoProviderFactory still works even without the TranslatorBag. WDYT?
