Error when opening mundo if undo history is in `undofile`/`undodir`
calebeby opened this issue · comments
Here are the steps I did:
- Add to vim config:
set undodir=~/.vimdid set undofile - Edit a file, creating some edit history:
nvim ~/.vimrc - Close file
- Open file again
- Open undo tree in file
Then this error pops up:

pynvim.api.common.NvimError: Vim(undo):E830: Undo number 2 not found
I repeatedly press <esc> to close the error message and it keeps popping up, exactly the same, with the same undo number in the message.
If I switch to the editor view and make edits to the file, the undo tree is refreshed and I can go back to the undo tree without errors. It shows all the previous history correctly.

Let me know if there's any more information that would help diagnose the issue!
Can confirm, with a minimal vimrc
set nocompatible
call plug#begin('~/.vim/bundle')
Plug 'https://github.com/tpope/vim-sensible'
Plug 'https://github.com/simnalamburt/vim-mundo'
call plug#end()
You don't need to even write or close the file to trigger the error.
git bisect shows that it was broken by c0d814b from #122.
The workaround is just manually checkout the previous working commit in the plugin directory (assuming a plugin manager): 595ee33
Since every :PlugUpdate breaks this again, a slightly more permanent fix is to use my fork which I will keep at 595ee33 until this issue is fixed:
Plug 'TamaMcGlinn/vim-mundo'
I will delete my fork when this issue is fixed, so you get an error and will know to switch back.

Thank you @simnalamburt, works great!
