To-Do

  • Remove old remote-settings client, which uses endpoints and logic that are not supported

  • Update implementations in consumer applications

Follow-ups

  • Increase poll frequency of new remote-settings client
  • Add v2 service support
  • Add signature agility
  • Add glean telemetry

This is looking good overall, but I had a couple suggestions. Also, I think the branch needs a rebase or something, because there's some extra commits here that don't seem like they belong.

Is anyone using this? It seems like this could only affect Rust consumers since it's not exported via UniFFI, but those are all getting updated by this PR right?

Ah, perhaps I'm misunderstaning something. But I found this reference in kotlin in firefox and thought I would need a temporary alias to transition things.

I think your reference is correct, but I don't think the type alias will prevent the breaking change. For that to happen, UniFFI would also need to create a type alias in the generated code and I don't think there's a good way to do that currently.

I think the best solution is to just accept the breakage and create PRs for iOS and Desktop/Android that replaces RemoteSettingsConfig2 with RemoteSetttingsConfig. Sorry about this step, it's pretty annoying, but the replacements should be pretty straightforward at least.

All good. I opened a patch to get the client code updated. I think that will take care of everything.

Rebased and adjusted based on PR feedback. Still have an open question on the config alias.

The changes in this repo look good to me, so I'm approving this one. However, don't merge it before you have PRs ready for the other repos since I don't think there's a way to avoid making this a breaking change.

Assuming I'm right about the alias, you'll need to update this line.
