What did you do?

This is a follow up to #44035. Thanks very much @heschik for addressing that issue in golang/tools@706a59c.

I've just tried this out, but I'm still not seeing workspace edits for go.mod. Given your change had test coverage, I suspect this is a configuration issue of some sort but I can't see what that might be.

I started with the same setup as before:

-- go.mod --
module example.com/repro

go 1.16
-- main.go --
package main

import (
	"fmt"

	_ "golang.org/x/tools/imports"
)

func main() {
	fmt.Println("hello, world!")
}

i.e. the requirement on golang.org/x/tools/imports is missing from go.{mod,sum}.

Loading main.go in Vim (using govim) gives error diagnostics as expected:

main.go|6 col 4| could not import golang.org/x/tools/imports (no required module provides package "golang.org/x/tools/imports")
main.go|6 col 4| golang.org/x/tools is not in your go.mod file

If we ask for suggested fixes at main.go:6 we get a code action response with the gopls.add_dependency command.

If we execute the gopls.add_dependency command, go.{mod,sum} change beneath the editor and gopls, i.e. we don't see any workspace edits, despite the changes in golang/tools@706a59c.

Log files:

Is there something we (govim) are not doing right here?

As a side note, I suspect the tempModfile option is no longer valid given that we have allowModfileModifications? Because I initially had tempModfile: true and this resulted in the error message:

-modfile is unsupported for this Go version

But I can raise this as a separate issue if needs be.

What did you expect to see?

gopls.add_dependency resulting in workspace edits for go.{mod,sum}.

What did you see instead?

The files changing beneath the editor, and that change getting detected by the govim file watcher

Sending workspace edits for a closed file causes VSCode to open it and leave the edits unsaved, which is undesirable, particularly for go.sum. To avoid that, gopls still directly edits closed files. You should see workspace edits if you open go.mod first.

I did try out Pauls example (using the defaults; tempModFile: true / allowModfileModifications: false) according to:

  1. Open main.go
  2. Apply the suggested fix, i.e. calling execute for the provided gopls.go_get_package:
[Trace - 23:56:03.030 PM] Sending request 'workspace/executeCommand - (5)'.

golang.org/x/tools/imports","AddRequire":true}]}
  1. Send didChangeWatchedFiles for go.mod and go.sum as the file watcher detects the updates:
[Trace - 23:56:04.156 PM] Sending notification 'workspace/didChangeWatchedFiles'.
Params: {"changes":[{"uri":"file:///private/var/folders/j4/l2j99h6d5qd6knjlllql0bb80000gn/T/tmp.7WMpQpFw/go.mod","type":2}]}

Then I get a couple of other go.sum diagnostics back for both main.go and go.mod:

Is there something I'm missing out? (full log at https://gist.github.com/leitzler/d189c42bdb0dae8562682b47325938e2).

Just to add to the above, I expected that applying the suggested fix would have the ~same effect as running go get golang.org/x/tools v0.1.0 before I open main.go.

If I do run go get before, then I only get one diagnostic (warning) telling me that the require line should be direct (ideally gopls would fix that as well executing gopls.go_get_package).

@leitzler: I don't see how your problem is related to workspace edits, but it is a real (and rather embarrassing) mistake on my part, so I'll file a new bug. Thanks for the report.
