Shell command history messing up when switching windows/slices

[afrixs]

My shell command history gets messed up when I switch among the terminals while running long-running commands in them. This happens when HISTCONTROL=ignoreboth is set in .bashrc or when set -g @resurrect-save-shell-history 'on' is set in .tmux.conf.
Since resurrect-save-shell-history is an experimental part of a tmux plugin, I'm going to concern on the basic usecase with HISTCONTROL=ignoreboth set.

How I reproduce it:
.bashrc:

case $- in
    *i*) ;;
      *) return;;
esac
HISTCONTROL=ignoreboth

.tmux.conf: empty

commands:
tmux
Ctrl+C
top
Ctrl+C (stops top)
prefix+c
ls
prefix+0
Up arrow (displays top)
Enter (runs top)
prefix+1
ls
prefix+0
Ctrl+C (stops top)
Up arrow (displays ls, should display top)

System: Ubuntu 18.04.2 LTS
Terminal: reproduced both in Ubuntu terminal and Konsole
$TERM (inside mux): screen-256color
$TERM (outside mux in both in Ubuntu terminal and Konsole): xterm-256color
tmux -V: tmux next-3.0
logs:
tmux-server-32284.log

Bug does not occur after removing HISTCONTROL=ignoreboth from .bashrc.

Note: while dealing with this issue I created a hack which overcomes it, so for those who experience similar problems and want to use the command history temporarily while the bug is not fixed, this is a script that performs custom history saving (it uses $HOME/.tmux/resurrect/ path for saved history files to be compatible with @resurrect-save-shell-history but this path can be changed if you don't use tmux_resurrect), just put it into .bashrc. Note2: the history starts working correctly in each individual terminal after executing the first command (ie. " echo >> 0" with the leading space)

This sounds like a Bash problem, not a tmux problem?

found some bugs in the workaround, gonna fix it in the evening

There is no way for tmux to affect the shell history, it is entirely within the shell's control. You will need to ask the Bash developers.

Ok, going to report it there. Just adding the corrected workaround script if someone finds this thread with the same problem (see the notes at the top of the script)
