Apparently one can create a command-line-arguments package with zero CompiledGoFiles:

xtools$ echo "" > b.go
xtools$ go list -e  -compiled -json  ./b.go
{
    "Dir": "/Users/adonovan/w/xtools",
    "ImportPath": "command-line-arguments",
    "Match": [
        "./b.go"
    ],
    "Incomplete": true,
    "Stale": true,
    "StaleReason": "build ID mismatch",
    "GoFiles": [
        "b.go"
    ],
    "InvalidGoFiles": [
        "b.go"
    ],
    "Error": {

27 reported crashes this week... I really need to make some progress on this one.

Comment From: adonovan

The bug indicates that there are multiple .go files in a command-line-arguments package. This is perfectly valid for go list a.go b.go when multiple .go files (and only .go files) are given as argument patterns, but it should never happen in gopls. Gopls has only one call to packages.Load, in Snapshot.load, and its query arguments come from the loop over scopes, which asserts that if there is a fileLoadScope (file=foo.go), then it must be the sole one.

Crazy thought: Is it possible for strings of the form "*.go" or "file=foo.go" to arise from the other kinds of scopes? If so, it would have to be a packageLoadScope; the others all have other suffixes. These strings are created in reloadWorkspace, from the PkgPath values in the shouldLoadRange map. They all originate from Metadata.PkgPath and Metadata.ForTest. Is it possible for a PkgPath to end in .go? Yes (see below). Is this common? Very much not.

So I think the answer must lie in go list. Perhaps @matloob has some insight.

xtools$ cat h.go/h.go 
package ff
xtools$ go list -json ./h.go

Comment From: matloob

The go command explicitly checks to see if a ".go" pattern is not a directory when making a command-line-arguments package. See https://cs.opensource.google/go/go/+/master:src/cmd/go/internal/load/pkg.go;l=2791;drc=94aeedc33a4434f0d410be7c42e0bbcdaedd790f . Otherwise the pattern is treated as matching a package. The linked code also links to issue #34653, where a bug was reported (and fixed) about ".go" packages not being supported.

Comment From: siddharthab

Hi @adonovan, thank you for keeping this issue open and continuing to investigate.

I was hitting an issue with gopls and traced it down to this bug. A second compiled Go file comes from CGo in my case. Reproduction is fairly simple. Filed it as #69564.

Comment From: findleyr

@siddharthab brilliant, your example reproduces this bug:

> cat main.go
//go:build ignore

package main

import (
        "C"
        "fmt"
)

func main() {
        fmt.Println("hello")
}

> gopackages -json main.go

Reopening since this has been observed in gopls/v0.17.1. (We should automate that; #71045.)
