go1.7rc6 darwin/amd64 autocompletion panic

[mattetti]

I tried to update to the latest and hopefully final RC of Go 1.7 and I noticed that autocompletion broke.

I know that the binary output changed in 1.7 and I updated all the go tools vscode reported using. The README says gocode version is used for autocompletion and I wonder if the API changed?
The extension panics but I can't find any specific errors or trace anywhere.

I am using a local build in debug mode and found what I think is the root cause, gocode is hanging when asking for autocompletion:

gocode -f=json autocomplete "path/to.my/file_test.go" c42

Doesn't return

This looks suspiciously similar to #322 which was fixed. However nsf/gocode#305 seems to indicate gocode doesn't yet support 1.7 With 1.7 out in a few days, this might cause some serious issues for VSCode users.

Good news everyone, I found the root cause. The problem is that I updated Go to 1.7 but Gocode was running its daemon in the background and wasn't aware of the change of version. Gocode uses a server/client architecture and VSCode was trying to communicate with the server but the request was hanging. Restarting gocode solved the problem and everything is great again!

tl;dr: restart gocode

If you encounter this issue, in your terminal, type:
gocode close

Then restart Code and everything should be working well again.

'gocode' is not recognized as an internal or external command,
operable program or batch file.

Actually only updating gocode worked for me (restarting didn't)

If use windows

cd $HOME$/lib/bin

gocode close

example:

cd D:\Development\Go\Lib\bin
gocode close
