x/tools/gopls: comments duplicated with CRLF files

[fonini]

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

$ go version
go version go1.15.5 windows/amd64

Does this issue reproduce with the latest release?

Yes

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

go env Output

What did you do?

I'm using VSCode with the latest gopls (0.5.4).
When I save a Go file in the VScode editor (Windows with CRLF), the comment section is getting duplicated.

What did you expect to see?

The file to be saved correctly.

What did you see instead?

The comment section being duplicated.

[tomqwpl]

Also see this issue. I think I upgraded the language server in the last couple of days, not sure how I tell what version I'm running.

[fonini]

@tomqwpl You can run gopls version

[tomqwpl]

Running that in a terminal window within VSCode gives:

  golang.org/x/tools/gopls v0.5.4
      golang.org/x/tools/gopls@v0.5.4 h1:PkQWDfzw8CxoseHDQniF2GhzmndN8KnQL6gcG2gnF3Y=

What I wasn't sure about was whether this was what was being used by VSCode.

[hyangah]

@tomqwpl The easiest is to check from the UI (https://github.com/golang/vscode-go/blob/master/docs/ui.md#language-server-status). Another way is to check Go: Locate Configured Go Tools output to find the path to the gopls binary.

[tomqwpl]

Go: Locate Configured Go Tools produces nothing in the output, but clicking on the go version number in the status bar brings up a menu with "open gopls trace v0.5.4", so that appears to be what I have. Which makes sense, since I upgraded a couple of days ago after a prompt.

I don't always see these symptoms. And when I do, changing the comment to be a single line, rather than a multi line comment makes it go away.

For example, right now I have this:

// Config describes a common configuration block
// for a database connection
type Config struct {
	// Type is the type of database. Currently supported database types
	// are:
	//   postgres
	Type   string      `json:"type"`
	Config StoreConfig `json:"config"`
}

If I press save, the "for a database connection" line is duplicated, so I get two copies. Press save again, and the whole thing is duplicated, so I have 4 copies of that line, and so on. The first line is not duplicated.
Change that to a single line comment and the problem goes away.

[hyangah]

I confirm this is reproducible with the latest version of gopls (v0.5.4)
