gocode panicked

[osleg]

With autocomplete on there are some (rare) cases where I get gocode panicked. Use :messages / see above for error details

Here a screen shot

This happens in 2 cases:

1. If the package referred is not imported yet like above, eg

package main

type A struct {
  sync.Mutex
  i int
}

func main() {
  a := A{}
  a.M   // Gocode panic occurs
}

2. When running vim/go under non unix GOOS, eg

$ GOOS=windows vim

And then this code

package main

import "sync"

type A struct {
  sync.Mutex
  i int
}

func main() {
  a := A{}
  a.M   // Gocode panic occurs
}

I cannot reproduce the both problems with https://github.com/mdempsky/gocode.
And it is not deoplete-go's issue.

I'm using the latest gocode from the same repository above.
And I feel like it does deoplete issue since running gocode directly on the file does provide results:
Without GOOS:

$ gocode -f json --in main.go autocomplete 96
[0,[{"class":"func","package":"","name":"main","type":"func()"},{"class":"package","package":"","name":"sync","type":""},{"class":"type","package":"","name":"A","type":"struct"},{"class":"var","package":"","name":"a","type":"A"}]]

With GOOS:

$ GOOS=windows gocode -f json --in main.go autocomplete 96
[1,[{"class":"type","package":"sync","name":"Map","type":"struct"},{"class":"type","package":"sync","name":"Mutex","type":"struct"}]]

Offset 96 is right after the . on line 12 a.M| where | is cursor position
Hence gocode doesn't actually panicking when trying to parse the data whether with GOOS or without.

If so, why I don't reproduce the problem?
Please upload the minimal init.vim to reproduce it.

And deoplete-go is open source project. You can research the problem.

Hm... I removed deoplete and then installed it again and it works 🤔 probably was something wrong with my install

[osleg]

@Shougo was about to do minimal vimrc but it started to work 🤷‍♂️

[Shougo]

Oh... I see. I think gocode close is needed.
