I'm implementing https://bugzilla.mozilla.org/show_bug.cgi?id=1956132 right now in order to unblock the UniFFI upgrade/FF android nightly bump. To get this merged ASAP, I'm just going to create a new RemoteSettingsService instance, meaning that Suggest and Relevancy will both create a separate instance.

This isn't ideal, instead we should be creating an app-wide remote settings service and sharing it between Suggest, Relevancy, and any other Rust components that need it.

• Hooked the RustSharedRemoteSettingsService code to the Region module.
  The new system updates the app context as the home region changes.

• Updated RemoteSettingsService.updateConfig to be sync rather than
  async wrapped. It should execute quickly and I want to have
  confidence that the config is actually updated when that function
  returns.

• Updated/Simplified the SuggestBackendRust.sys.mjs testing code. Now
  we just need to track if we should disable the Rust backend for the
  tests or not.

TODO:

• vendor app-services
• check ./mach test browser/components/urlbar/tests/quicksuggest/unit/test_quicksuggest_remoteSettingsFilter.js

Backed out for causing bc failures @browser_quicksuggest_dynamicSuggestions.js and @browser_glean_telemetry_reenter.js.

• Backout link
• Push with failures @browser_quicksuggest_dynamicSuggestions.js
• Push with failures @browser_glean_telemetry_reenter.js
• Failure Log @browser_quicksuggest_dynamicSuggestions.js
• Failure Log @browser_glean_telemetry_reenter.js.

I tried looking through those failure logs, but I don't understand them at all and the tests pass when I run them locally. Drew: can you point me in the right direction here?

browser_quicksuggest_dynamicSuggestions.js hung, and the last thing in the log is this line. So it hung either on the next line waiting for QuickSuggest.init() or after that in the call to QuickSuggest.rustBackend._test_setRemoteSettingsConfig().

I can't reproduce it either. I tried running the test by itself and then all browser tests up to and including that test. It looks like the hang only happened on Windows, so maybe there's something specific about the CI Windows machines -- not Windows itself but the timings or something is different on them.

If you're not on Windows either and you have a Windows machine/VM handy, I would try reproducing it there. The next thing I would do (or concurrently) is add more logging to QuickSuggestTestUtils around those lines and also to the code under test, just some console.log() calls with messages you can easily search for in the logs. Then push to try and see what it logs.

(In reply to Drew Willcoxon :adw from comment #6)

or after that in the call to QuickSuggest.rustBackend._test_setRemoteSettingsConfig().

Sorry, QuickSuggest.rustBackend._test_setRemoteSettingsService() I mean.

https://hg.mozilla.org/mozilla-central/rev/874e3a717cc7

I pushed out a try run with the same tasks yesterday and they all passed except one. This makes me think it's a timing thing and my hunch is it's caused by many different operations queued to the RemoteSettingsService.

I added back my the change to browser/components/urlbar/QuickSuggest.sys.mjs that makes it so we wait for ingestion to finish before changing the remote settings service URL in _test_reinit. The theory here is that the slowdown is caused by multiple suggest features all hitting the remote settings service at the same time. I'm not sure if that's right or wrong, but I don't think that change can hurt anything. I made another try run and that error didn't show up, although a test still failed because the overall timeout expired.

I'm not totally sure about if this is fixed, but it does feel very intermittent to me. I'm going to try landing this again early next week.

Revert for causing browser-chrome crashes.

That LateWriteObserver crash is very similar to one I hit when I was integrating desktop with the Rust revision that used the new RS API in Suggest. I fixed it by adding a blocker on AsyncShutdown.profileChangeTeardown and nulling the JS reference to the SuggestStore (#store) so that the store is dropped in Rust earlier in the app shutdown process, source here.

It looks like ContentRelevancyManager already uses the same shutdown blocker barrier, so that should be early enough in the shutdown process, but it doesn't null its #storeManager, so doing that might fix it.

I think that's spot on. I'm thinking we might be able to shutdown things more explicitly, since I added some code that closes the connection when RelevancyStore.close() is called. We might just need it hook that up to the shutdown blocker that Drew mentioned.

I think I've finally figured this one out. The issue is that we always shutdown the relevancy store -- even if it was never enabled. The latest try run looks good, I'm going to try to land this again.
