Disable Zsh history completely

I would like to disable Zsh history (arrow up) and zle history search (namely esc+p) completely. How can I achieve this?

My current .zshrc:

unsetopt hist_append
unsetopt hist_expand
HISTFILE=
HISTSIZE=SAVEHIST=0

Currently I have history buffer of one, but I'd like to have history of zero.

21-10-2016 Update:

I've added

bindkey -r "^[p"
bindkey -r "^Xr"
bindkey -r "^Xs"
bindkey -r "^[[A"
bindkey -r "^[[B"
bindkey -r "^[n"

to get rid of history features that I use (esc+p is deeply hardwired to my backbone - so difficult to unlearn).

I use following entries in my .zshrc:

alias disablehistory="function zshaddhistory() {  return 1 }"

If function zshaddhistory is defined, it can control whether history line will be saved.

Therefore, alias disablehistory will just define function that always returns 1 (don't save).

alias disablehistory="function zshaddhistory() {  return 1 }"

alias enablehistory="unset -f zshaddhistory"

enablehistory just unsets function set by previous alias.

If you want to disable history completely, permanently define zshaddhistory in your .zshrc

Try configuring your ZSH setup to run a postexec function that empties/deletes your .zhistory file. It's a hacky workaround but should probably work.

I don't see anything in the zsh man page that completely disables history. Even setting HISTSIZE=0 seems to reset the value of HISTSIZE to 1.

You'll probably have better luck changing the key bindings with bindkey so that history features never occur. For example, bindkey -r "^[[A" for my up-arrow key (note that I actually typed a caret and two brackets, not an escape key).
