Describe the bug

VSCode is running on macOS, vscode-go is running on linux/amd64 (I'm using the remote-ssh extension).

I just upgraded to gopls 0.60. Now vscode is yelling at me about the workspace needing go.mod changes, presumably due to the -mod=readonly change introduced to gopls 0.60. The status bar reads "Error loading workspace", and has a permanent spinner.

I'm not aware of anything I can do configuration-wise to solve this problem, so I think this might count as a bug. Not entirely sure.

Error loading workspace: go [-e -json -compiled=true -test=true -export=false -deps=true -find=false -- builtin github.com/myorg/platform/api/compiled/go/...]: exit status 1: go: updates to go.mod needed, disabled by -mod=readonly

Any help would be appreciated. Thank you.

Do you see any diagnostics on the files in your workspace, likely on a go.mod file? You can check by opening the Problems pane via the Command Palette (Ctrl+Shift+P -> Problems: Focus on Problems View). If there is a diagnostic, it will have an associated suggested fix which you can apply.

Hi @stamblerre

Yes, looks like there is a diag line in there. The fix seems a bit busted though, it's two empty entries. I'm a little wary of clicking on them. 😅

I guess I could run "go mod tidy" manually. It seems a little unfortunate though, from a workflow perspective. Is this expected to be the normal workflow for vscode-go going forward with gopls >= 0.60?

Thank you!

The fix seems a bit busted though, it's two empty entries. I'm a little wary of clicking on them. 😅

I'm not sure I understand this--what empty entries are you referring to? All that fix will do is run go mod tidy in your module, which is the same as running it on the command line.

And yes, the go command is defaulting to -mod=readonly which means that, in the future, any go build or go test command will break until your module is tidied. gopls is just adopting this behavior a little bit early--before Go 1.16.

@stamblerre Notice the menu dropdown. I'm assuming there are two fixes listed there, but they are both blank, i.e. they don't describe what they do, their name, or anything. So I'm being asked to click on a menu item which is blank. I suspect there's supposed to be some text there.

[stamblerre]

Oh I didn't realize that was a drop-down menu. Thank you for pointing that out--I will transfer this to the gopls issue tracker and make sure we get a fix in for that.

[zhaytee]

Sounds good. Thanks for letting me know about the expected workflow going forward!
