I still can't repro, so all I can do is show a cleaned up error.

I can repro in gvim in windows.

puremourning commented 4 years ago

in fact, it's worse because vim gets stuck in a mode where you can't do anything, it just keeps saying "Not allowed in a popup window"

minimal vimrc:

" windows default encoding is not supported
set encoding=utf-8

set guifont=Lucida_Console:h9:cDEFAULT

" If you using neovim and python isn't loading, copy your python setup from your
" vimrc here:

" let g:python3_host_prog = '/path/to/python3/with/neovim/module'
"
" But remember that neovim is not officially supported, so please reproduce in
" Vim.

" Enable debugging
let g:ycm_keep_logfiles = 1
let g:ycm_log_level = 'debug'

" If the base settings don't repro, paste your existing config for YCM only,

"popup_clear()" can't close terminal popup windows #5745

puremourning commented 4 years ago

I can repro in macOS on latest vim too.

puremourning commented 4 years ago

I think this was broken when we added completion in empty buffers.

We need to blacklist some more buftypes:

popup
nofile

try this patch:

diff --git a/autoload/youcompleteme.vim b/autoload/youcompleteme.vim

Use this patch, I have not yet repro it.

puremourning commented 4 years ago

I think this is a workaround while we try and understand this.

let g:ycm_filetype_blacklist = {
      \ 'ycm_nofiletype': 1
      \ }

@habamax FYI. It looks like the patch to add empty-filetype support caused this really weird regression. I don't think that's strictly the issue, but it's highlighted a problem where the &filetype of popup windows shimmers:

Parsing file FileType cpp
Clear signature help File Ready to parse
Parsing file Resend
Clear signature help File Ready to parse
Enter buffer 2 ,  , popup
Reparse required for 2 ,  , popup : 0
Enter buffer 2 ,  ,
Reparse required for 2 ,  ,  : 1
Reqruies reparse 2 ,  ,
Parsing file OnBufferEnter
Clear signature help File Ready to parse
Enter buffer 1 , cpp ,

See there that buffer 2 goes from popup to ` buftype (Enter buffer 2 , &filetype , &buftype `). Ultimately this makes us try and parse the signature help popup and any preview popup that goes with it. I think it might be a vim bug, but we may have to revert the YCM change in the interim, or try and turn it off by default.

I have tried to get this error with python, golang and godot and couldn't repro anything similar there.

About reverting the patch -- yeah, would be unfortunate for me, but I always can use forked unreverted repo.

puremourning commented 4 years ago

I'm thinking that we could blacklist ycm_nofiletype for now (and you can "undo" that in your vimrc)

yeah, sure!
