gopls version: (devel) (go1.20.6)
gopls flags:
update flags: proxy
extension version: 0.39.1
go version: 1.20.6
environment: Visual Studio Code darwin
initialization error: undefined
issue timestamp: Mon, 31 Jul 2023 20:31:59 GMT

I'm writing a code generator that makes heavy use of templates, and gopls crashed after I generated an invalid struct like type Thing struct { OtherThing Thing, ...} because I forgot to make those fields a pointer. I managed to fix the generator and it produced a valid result, but within 5 seconds VSCode froze entirely, and after it recovered is when I was prompted with the gopls crash message

I've also attached errors that were sandwiched between the stack traces, since they show up everytime gopls restarts, but they may not be related. The errors are a result of me using the "files.associations" setting in vscode and setting "*.go.gtpl": "go" in order go get better syntax highlighting in go templates that generate go code. Again, this may or may not be related to the crash since it hasn't been a problem for me so far.

Thanks, this looks like a bug in the copylock analyzer!

Hmm, it doesn't naively reproduce, as the type-checker likely breaks cycles in most cases.

In any case, transferring to the go issue tracker.

Just to be sure: is this reproducible? I would guess it is not, as we should only encounter cyclical types when there are type errors, and you likely don't have any type errors any more. If it is reproducible, please let us know as I'd have more questions.

I can confirm that I'm able to reproduce it, but I can't quite figure out what's causing the issue enough to produce a minimal example. If I generate just the offending type(s), then it errors but doesn't crash. When I generate the rest of the code, it crashes when certain functions (that use those types) are generated, but other functions (that also use the types) don't cause it to crash.

I am able to make gopls crash consistently with the following:

type A struct {
	a A
}

type B struct {
	a A
	b B
}

func okay(x A) {}                  // <- safe
func sure()    { var x A; nop(x) } // <- safe

var fine B     // <-- safe
func what(x B) {}                  // <-- crashes
func bad()     { var x B; nop(x) } // <-- crashes
func good()      { nop(B{}) }                   // <-- safe
func stillgood() { nop(B{b: B{b: B{b: B{}}}}) } // <-- safe
func nope() { nop(B{}.b)}  // <-- crashes

func nop(any) {} // only used to get around unused variable errors

Thanks so much for the repro! I've confirmed that this is reproducible with just the analysis framework.
