TabNine hangs with ctags when YCM semantic triggers #7

Closed yous closed 3 years ago

yous commented 6 years ago

I think TabNine processes tags file also, and this cause some bugs. Because it's in global gitignore, TabNine doesn't know it should be excluded.

This would reproduce the problem:

git clone --depth 1 https://github.com/gcc-mirror/gcc.git
cd gcc
ctags -R

I'm using Homebrew Vim 8.1.500. The minimal test.vimrc:

set nocompatible
call plug#begin()
Plug 'zxqfl/tabnine-vim'
call plug#end()

I used Exuberant Ctags 5.8.

$ ctags --version

Run vim -u test.vimrc gcc/cfgrtl.c and go to line 279. Press o to append after that line, then type bb_note->. Then Vim hangs. When I press Ctrl-C, the following messages are displayed:

This is related to YCM semantic trigger. When I add custom semantic triggers to invoke on every word longer than or equal to 4 letters:

let g:ycm_semantic_triggers = {
      \ 'c': ['re![_a-zA-Z]\w{3,}'],
      \ 'cpp': ['re![_a-zA-Z]\w{3,}'] }

Press o on line 279, and type bb_note, one space, and one backspace, then Vim hangs.
