Panics with unknown export format version -1 about gocode HOT 16 OPEN

Hm, turns out my test case was wrong, it works for me with Go 1.11beta2 and mdempksy's fork at https://github.com/mdempsky/gocode

from gocode.

The fork at https://github.com/mdempsky/gocode fixes this issue.

Okay, I found it, it's called indexed export format and has been introduced recently: https://groups.google.com/forum/#!msg/golang-codereviews/6vqMfk1krNU/lzoJtkbuCQAJ

Some more info: https://groups.google.com/forum/#!topic/golang-dev/Lj_B-O6OMv8

Gocode is no longer maintained, you can try a fork, such as: https://github.com/mdempsky/gocode

from gocode.

I'm getting this as well after switching to Go 1.11beta1. Switching back to Go 1.10 seems like has no effect. Maybe it's a coincidence, I don't know. I'm on latest MacOS X.

Also, I was using GOOS=js GOARCH=wasm for the build when I start getting those crashes, if it's related.

Any suggestions on how to debug this issue?

from gocode.

Another detail, that may be relevant: my Go 1.11 installation is a binary installation (I didn;t compile it myself).

Package files seems to have totally different encoding that crashes gocode. I can't find docs or commits that explain the diff, though.

Here is an output of pkg files for fmt for Go 1.10 and Go 1.11.

There is no version info and that's causing a crash.

Yeah I ran my own go 1.10+dev when I started seeing this.

from gocode.

So the proper solution would be to implement a parser for the indexed export format. I started to work on this, but it might take longer than by people who already worked with it. It actually requires a lot of copying and adapting from internal packages of Go codebase.

from gocode.

Is it correct that until gcode understands the new format, it is broken for Go >= 1.11?

from gocode.

I've opened an issue over at mdempsky#43

from gocode.

I do not understand why this issue is closed... I am keep getting panic with go 1.11

from gocode.

It's not closed

from gocode.

oh, yes... sorry

from gocode.

Same issue here, even with go-langserver. Not working with go 1.11.

from gocode.

I'm having the same issue after upgrading to go 1.11

from gocode.

Hi! Is there a workaround for this issue. I am seeing the same with go version go1.11 darwin/amd64
