gopls flags:
update flags: proxy

go version: 1.20.5
environment: Visual Studio Code darwin

ATTENTION: PLEASE PROVIDE THE DETAILS REQUESTED BELOW.

Describe what you observed.

gopls server started crashing after update. It crashes right after launching VSCode or installing Go extension.

I've tried:

  • downgrade to previous release of gopls
  • downgrade to previous of that
  • update go (1.19.8->1.20.5)
  • Go extension nightly version
  • Update/Reinstall VSCode
  • reinstall gopls via CLI
  • Checked out other issues on Github, a lot of crashes, nothing that looks like my case

I would be grateful for a tip on how to make this work on any version (except for switching to vim).

To my surprise, only my "favourite" project makes gopls panic. I've created hello-world app, go.mod, go.work and everything seems fine in that window.

gopls server output (the one that's panicking):

Thank you for the stack trace. Transferring to the gopls issue tracker.

I'm not quite sure how this panic could be reached: it indicates a bug in either the type checker or importer. Is your project open-source?

We can put in a workaround for the crash, but it would be unsatisfying if we didn't understand how it is reached.

The CL above should make this panic more useful. Could you please build gopls @ master, and provide us the improved panic?

git clone https://go.googlesource.com/tools
cd tools/gopls
go install

Thank you!

This may be a consequence of #61561.

Closing this as I am pretty sure it is a consequence of #61561, and should have been largely mitigated by gopls@v0.13.0 (and fixed using go@master).
