I can reproduce this with:
- Vim 9.0.1355
- Git 2.34.1
- Ubuntu 22.04
I made sure my vimrc was not a factor by creating a file named vim
in my home directory:
#!/bin/bash
exec /usr/local/bin/vim -N -u NONE -i NONE "$@"
and starting git like this:
$ PATH=$HOME:$PATH git difftool
:r!git diff
I did notice that with my normal vimrc, the ":r!git diff" command
does not hang Vim, but instead inserts these three lines into the
buffer:
Vim: Warning: Output is not to a terminal
^[[24;1H^[[23;2t^[[23;1t^[[J2 files to edit
fatal: external diff died, stopping at src/search.c
where those ^[ are Vim's rendering of escape characters and
src/search.c is the only modified file in my Vim repo, where I ran
these commands. The difference is probably due to some workarounds
in my vimrc for other problems Vim has with launching sub-shells.
I haven't tried to identify the settings that affect this problem.
Regards,
Gary
