"[deoplete@yarp] Exception ignored in:" after recent yarp change

[mrbiggfoot]

Problem: after updating yarp plugin, start vim with deoplete, then exit it using ":qa!". There's a good chance that you will see this:

[deoplete@yarp] Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in: Exception ignored in:

Does not happen every time but quite often. The count of "Exception ignored in:" can vary. The yarp commit that causes it is this:

commit 1e53a01493ab41c6bd82737571826c9b378d8b0e
Author: roxma <roxma@qq.com>

    Add yarp#core#try_notify

    yarp.py

        - environ['NVIM_YARP_MODULE'] = module
        - assert __name__ == "__main__"

    autoload/yarp/core.vim

        - add yarp#core#try_notify()
        - unlet mod.channel in yarp#core#on_exit

I'm not sure whether it is a yarp or deoplete problem, so CC'ing @Shougo.

I have similar problem. After exiting vim with q! I see this:

But exit with file save (wq) works good.

I cannot reproduce the issue

I need more information, vim8 version, os environment, minimal vimrc and reproducing steps

[poslegm]

@roxma unfortunately your PR not helped for me. And after installing it I have [deoplete@yarp] Exception: method deoplete_init not found message on vim startup.

Vim version: 8.1.22 OS: Arch Linux Minimal .vimrc:

call plug#begin('~/.vim/plugged')
" ============= Vim-Plug begin ===============
if has('nvim')
  Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
else
  Plug 'Shougo/deoplete.nvim'
  Plug 'roxma/nvim-yarp'
  Plug 'roxma/vim-hug-neovim-rpc'
endif
" =============== Vim-Plug end ===============
call plug#end()
let g:deoplete#enable_at_startup = 1

Reproducing steps:

1. Open vim: vim .vimrc
2. Type :q!

[roxma]

I've push an update, please try the latest version

[poslegm]

@roxma latest version of your PR don't solve this issue.

But I found the cause of the problem. In file autoload/yarp/core.vim you moved code block

if has_key(self, 'job')
    return
endif

to the beginning of the function yarp#core#jobstart. I returned it to its original position and the errors was gone.
