non-exist package should not cause problem

[chinglinwen]

The issue is come from here: golang/go#36899 (comment) , as stamblerre suggest, I'm not sure what's the real problems though.

It's true, that cfg package is not exist, it's somewhat old package exist once, now deleted. or changed naas to example.com/naas I can't remember. and it should not cause problem I think.

What version of Go, VS Code & VS Code Go extension are you using?

• Run go version to get version of Go
  • go version go1.15 linux/amd64
• Run gopls -v version to get version of Gopls if you are using the language server.

Describe the bug

A clear and concise description of what the bug.

It may relate to #236

However I try with extreme case that full of undefined names ( and no such import etc), in that way, it will show the saving box ( about 10 seconds I guess ), and got three times vscode disconnect(auto reconnect though).

A clear and concise description of what you expected to happen.

not sure if relate to this issue, if it relate, here's the expected to happen.

• The saving box gone(so needs faster timeout? I'm not sure), no more discconect.

Steps to reproduce the behavior:

• create a directory named afinalizer
• with this content: https://mclo.gs/quI970t
• under $GOPATH/src/example.com/pkg/afinalizer ( if it relate)

try save and close(sometimes close not responding) etc

logs: https://mclo.gs/QM2qthv

Thanks for filing this new issue. One thing to try might be to reinstall gopls, because the version number you shared is a little unexpected (it should say v0.6.2, not master at the top). Can you please try running GO111MODULE=on go get golang.org/x/tools/gopls@v0.6.2?

@hyangah may be able to shed more light on the nature of the error message, but it looks like that you are still using that nonexistent package in your code. See this error message, for example:

[Trace - 12:41:19.646 PM] Received notification 'textDocument/publishDiagnostics'.
310 | Params: {"uri":"file:///home/wen/gocode/src/example.com/naas/example/test/test.go","diagnostics":[{"range":{"start":{"line":13,"character":1},"end":{"line":13,"character":27}},"severity":1,"source":"compiler","message":"could not import example.com/naas/pkg/cfg (no required module provides package \"example.com/naas/pkg/cfg\")"}]}
311

Do the issues go away after restarting gopls or do they persist?

[chinglinwen]

@stamblerre It's stranges that after do go get golang.org/x/tools/gopls@v0.6.2, it seems, it close fast as I expect about 1 seconds, though saving box happen sometimes ( not all times as before ).

And I can see the format works now(format in one second), even it's not valid code ( afinalizer.go ).

after above go get command, I don't find the build info changed though (https://www.diffchecker.com/yfjJOx9I)

$ gopls -v version

here some logs, if it helpful
as it works now ( no delay anymore ), I try reload window to see if it happens again, and even I do reload, it works too.

https://mclo.gs/qvm81pF

currently I have no other case to try to see if saving got issue again.

hope this help someone else too.

[chinglinwen]

Saving box still shows up, so above comment is false positive?

@chinglinwen Sorry for being late. Do you still experience the issue? I didn't have a chance to look into the logs but found they are no longer accessible.

Recently we rewrote our troubleshooting guide - please follow the instruction and share the traces if you still need help. If you manage to address the issue or no longer can reproduce the issue, feel free to close the issue.

[chinglinwen]

I've try reproduce again, can't reproduce the issue, so closing it.
