What did you do?

Support for autocompletion of unimported packages was introduced in this ticket #31906, but it seems not working, not sure if this feature has been deprecated. When you create a new package and import a value from such package in another one placed in the same workspace, no member is shown in the completions suggestions pop up. Attached a video as an example:

completion_unimported_packages.mov

What did you expect to see?

A list of candidates from unimported packages.

What did you see instead?

No candidates at all until I manually import a package.

Hi @dppascual, thank you for the report.

I think I know what this is. The unimported completion cache is built asynchronously in the background. If you added the v1 package recently, it will not show up in unimported completion.

If you restart gopls, you should get unimported completion for this package. Can you confirm?

Assuming that works, there is still a UX problem here: gopls knows that metadata has been invalidated, and so should invalidate the unimported completion cache eagerly.
