defx#do_action('drop') or defx#do_action('drop', 'split') sometimes make vim stucked

[Freed-Wu]

e.g.

gvim will get stucked util be forced to quit.

this is vimrc.

autocmd FileType defx nnoremap <buffer><expr> gi
            \ defx#do_action('drop', 'split')

OS: gentoo/Linux vim: gvim8.2

this error never appear in windows OS 10. there exists other circumustances to encouter this error. and defx#do_action('multi', [['drop', 'split'], 'quit']) will not trigger this error. cheers.

They are needed to reproduce? I need real minimal vimrc.

[Shougo]

And please upload the reproduce instructions. If not, I need to close the issue.

Note: I need 100% reproduce-able instructions. I don't need sometimes reproduce-able instructions. I can only fix reproduce-able problems.

[Shougo]

And have you tested the vimrc in the screenshot? I have tested it and not highlights.

[Shougo]

I have tested it in Vim8 and it is not reproduced for me. If you don't reply, I will close the issue.

[Freed-Wu]

syntax highlight is because /etc/vim/vimrc(the default system vimrc). I copy one line from system vimrc to test vimrc then delete the system vimrc. (in gif, i :scriptnames to display /etc/vim/vimrc have not be sourced.)

            \ defx#do_action('drop', 'split')

before test, I

cd /home/wzy/.config/nvim
mv init.vim init.vim.bak
touch init.vim
touch empty.txt

that edit init.vim as example.

and need

cd /home/wzy/.vim
ln -s /home/wzy/.config/nvim/init.vim vimrc

(in gif i cd .vim and ls -al to display it)

my vim is 8.2.0114(i :version to display it)

I use ttyrec and ttygif to record a gif.

open vim, then Defx /home/wzy/.config/nvim, then move cursor at line where init.vim at, press gi to see init.vim its content is as above example. then move cursor to empty.txt, press gi, vim will get stucked. i have to close this terminal by force. the ttyrec stop together.

the error is very strange. at first, i drop some file in defx will get vim stucked. so after backup my init.vim to init.vim.bak, i spend a bit time to delete many lines in my original init.vim to get the minimal vimrc. the map about go is spare but for true i leave it. except go, deleting any line will make the gvim cannot get stucked. especially that two plugins. if you can reproduce this error it will be good. if can not i will try to use defx#do_action('multi', [['drop', 'split'], 'quit']) to replace defx#do_action('drop', 'split') to avoid this error. and this error never appear in Windows OS 10. it confused me.

The plugins are really needed?? Please answer my question.

[Freed-Wu]

yes, and directory /home/wzy/.config/nvim/ must be deposited by git before test. i copy init.vim to other directory without deposition of git, test again will not see exclamatory mark on the left provided by signify, and the error will not appear, too.

and don't load plugin Leaderf will not result in this error. i test. it looks like they all don't have problem, but when they be loaded together, vim get stucked probably.

[Shougo]

OK. I get it. But your instruction is not reproducible for me. I will rewrite your instruction. Please wait.

[Shougo]

I have cloned your configuration repository. https://github.com/Freed-Wu/myInit.vim

cd ~/src/myInit.vim
mv init.vim init.vim.bak
touch init.vim
touch empty.txt

that edit init.vim as example.

cd /src/myInit.vim
rm vimrc
ln -s ~/src/myInit.vim/init.vim vimrc

[Shougo]

1. open vim
2. execute :Defx command
3. move cursor at line where init.vim
4. press gi to see init.vim its content is as above example
5. move cursor to defx window by <C-w>w
6. move cursor to empty.txt, press gi
7. vim will get stucked. i have to close this terminal by force. the ttyrec stop together.

[Shougo]

I have created the instructions to reproduce, but it cannot be reproduced for me. So I will close the issue later.

[Shougo]

Please don't use your configuration in /home/wzy/.config/nvim/. It is not reproduce-able for me.

[Shougo]

No response. I will close it later.
