Freezes since the latest update

[kantord]

Since the latest update, the plugin freezes on the second search.

On the first search, everything works fine but if I do a second search without exiting vim, it freezes forever.

I'm on NVIM v0.4.4

Thanks for the report.

Could you try with the minimal vimrc please?

1. Insert the following code into /tmp/vimrc:

   if !filereadable('/tmp/vim/autoload/plug.vim')
   exe 'silent !mkdir -p /tmp/vim/autoload && curl -fLo /tmp/vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
   endif
   set runtimepath+=/tmp/vim
   call plug#begin('/tmp/vim/bundle')
   Plug 'eugen0329/vim-esearch'
   call plug#end()
   PlugInstall | q
   filetype plugin indent on

2. Run nvim as nvim -u /tmp/vimrc

My steps are:

1. Press \\fa<enter>
2. Press \\fb<enter> and enter the pattern again.

My result is no freezes encountered (yet).

UPD Also provide your os name and any hints about the size of expected results please. If you have matches in minified js or svg files, it can result in some freezes, as vim itself tends to be slow when rendering huge files, but they still should be relatively small, not permanent.

Could you run this command in the console mkdir -p /tmp/vim/autoload && curl -fLo /tmp/vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim please?

Using this vimrc, it doesn't freeze

[eugen0329]

That's strange, as the last two commits affect only <c-c> click in the prompt and existing swap messages when writing.

Probably, the issue is with a vim plugin you use. You can try to binary search it by disabling plugins listed in :au WinEnter,WinLeave,BufWinEnter,BufWinLeave or I'll try you vimrc tomorrow.

It is because of this plugin: https://github.com/TaDaa/vimade

[eugen0329]

Can't reproduce with:

if !filereadable('/tmp/vim/autoload/plug.vim')
  exe 'silent !mkdir -p /tmp/vim/autoload && curl -fLo /tmp/vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
endif
set runtimepath+=/tmp/vim
call plug#begin('/tmp/vim/bundle')
Plug 'eugen0329/vim-esearch'
Plug 'TaDaa/vimade'
call plug#end()
PlugInstall | q
filetype plugin indent on

Also tried your config with these two plugins injected.

More ideas to reproduce:

1. Try to inspect htop output to see whether any remote plugins or lsp providers are stuck. I encounter the similar deadlock when I write a regular file or switch a tab, so this is probably a neovim bug.

2. Try to reproduce the bug on a different machine with a different os using your latest configs. You can use this Vagrantfile example to access it faster.

   Vagrant.configure('2') do |config|
   config.vm.box = 'ubuntu/focal64'
   
   config.vm.provision 'shell', inline: '
   curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim.appimage
   chmod u+x nvim.appimage
   mv nvim.appimage /usr/local/bin/nvim
   '
   end

Also provide your :version output, g:esearch configs and your os version please.

Sorry, I don't have Vagrant and I don't know if I'll have time to set it up. But I did a little bit more of trial and error and now it looks like if I enable the vim-buffet extension (which has to do with tabs) then I can consistently re-produce it.

BTW here's the list of all changes to my dotfiles since I installed vim-esearch: https://github.com/kantord/perfect-arch-config/compare/7c802d0c7eada9d86af7dd0efeba5a4172fd9d7d...master#diff-87302fb5f87b2db92b62050c696feff05c177e37d6a805297579189dff0df95fR7

Here is the place in vim-buffet. It gets into an infinite loop when i run the search 3rd time.

It seems that it has nothing to do with the version of the plugin you use:

if !filereadable('/tmp/vim/autoload/plug.vim')
  exe '!mkdir -p /tmp/vim/autoload && curl -fLo /tmp/vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
endif
set runtimepath+=/tmp/vim
call plug#begin('/tmp/vim/bundle')
Plug 'eugen0329/vim-esearch', {'commit': '3409f596097b552aa367d2a85a6193ba49f15c1b'}
Plug 'bagrat/vim-buffet'
call plug#end()
PlugInstall | q
filetype plugin indent on

In case you don't have much time to communicate with the author, you can add let g:buffet_hidden_buffers = ["terminal", "quickfix", "nofile"] workaround configuration to your init.vim.
