What version of Go are you using (go version)?

go version go1.14.6 darwin/amd64

Does this issue reproduce with the latest release?


What operating system and processor architecture are you using (go env)?


What did you do?

I keep my local gopls regularly updated from master. Sometime in the past 24h, a commit was introduced that has caused significant performance / hanging issues with gopls for me locally. Nothing is logged when this happens.

Commits Tried:

90696ccd - hanging/100% CPU
b4d825fe - hanging/100% CPU
d55f2edd - hanging/100% CPU

fec4f28e - working normally

What did you expect to see?

Normal gopls functionality.

What did you see instead?

100% CPU in activity monitor, VSCode not performing autocompletes/cannot code navigate/cannot save files due to waiting for code actions.

This may have been fixed in: golang/tools@ee49e49 - I am running from 9099c90c and it seems to be working again.
