Here's how I think I make sure it doesn't truncate:

  shopt -s histappend
  shopt -s cmdhist
  export HISTCONTROL=ignoreboth
  export HISTFILESIZE=-1
  export HISTFILE=~/.bash_eternal_history
  export HISTSIZE=-1
  export HISTTIMEFORMAT="%d/%m/%y %T "
  export HISTIGNORE="history:ls:l:ll:pwd:exit:clear"

It's almost a megabyte now... By when did it start to truncate for you?

somewhere around a few thousand lines. I want it to support tens of millions. I have a fast enough computer, storage is effectively free. I've tried all those things - everything short of doing a bunch of bpf filters and setting breakpoints on the binary myself.

honestly, with these modern systems this shouldn't be a problem any more. I look forward to it.

Yeah i have lots. Try my solution might work for you also.
