hstr stops working on linux >=6.2.0 (depending on kernel config)

[leapfog]

Just wanted to leave a note, that hstr stops working with linux kernel 6.2.0, when CONFIG_LEGACY_TIOCSTI isn't set. So maybe you want to add that information to a trouble shooting guide or FAQ or something.

(re: "stops working": the history can still be browsed, but cannot be inserted anymore)

I didn't saw the new parameter for bash export HSTR_TIOCSTI=y I think that now it should work.

[Dennysium]

I have the same problem on Ubuntu, since the upgrade to 24.04. That is kernel 6.8.0-31-generic and hstr 3.1.0 from the Ubuntu repos.

[jakedane]

@Dennysium it's your configuration. Compare hstr --show-configuration output with what you have in your .bashrc file.

[Dennysium]

@Dennysium it's your configuration. Compare hstr --show-configuration output with what you have in your .bashrc file.

Thank you. I have appended the hstr --show-configuration output to my .bashrc, but still having the problem.

[Dennysium]

I have updated a second pc to Ubuntu 24.04 (This is a Kubuntu machine). I have appended the output of hstr --show-configuration to my .bashrc file and run source ~/.bashrc. I have the described problem.

[jakedane]

The NO_TIOCSTI issues were fixed with hstr 3.1.0. There's no problem with hstr on Ubuntu 24.04 for me. If it doesn't work for you, your configuration is wrong. Did you scrub the old configuration? It only works with bash or zsh.

[Dennysium]

@jakedane Thank you for the clarification. I run bash, this is my bashrc. The latter part is what I appended from hstrt --show-configuration:

[Dennysium]

Just one more important note: Whe I use Ctrl + R ton invoke hstr, it works as expected. It does not work with hstr searchterm

[sbrl]

On Linux DEVICE_NAME 6.9.4-artix1-1 #1 SMP PREEMPT_DYNAMIC Wed, 12 Jun 2024 21:17:50 +0000 x86_64 GNU/Linux, hstr behaves as I would expect with the following in my .bashrc:

if [ "${NO_HH}" != "true" ] && [[ $- =~ .*i.* ]]; then
    # hh / hstr configuration (https://github.com/dvorka/hstr/)
    export HSTR_CONFIG=hicolor  # get more colors

    hstr_loc="";
    if which hh >/dev/null 2>&1; then
        hstr_loc="hh";
    elif which hstr >/dev/null 2>&1; then
        hstr_loc="hstr";
    fi

    hstr_mode="$($hstr_loc --is-tiocsti)";

    if [[ "${hstr_mode}" == "n" ]]; then
        # erk, no tiocsti available.
        function hstrnotiocsti {
            { READLINE_LINE="$( { </dev/tty ${hstr_loc} ${READLINE_LINE}; } 2>&1 1>&3 3>&- )"; } 3>&1;
            READLINE_POINT=${#READLINE_LINE}
        }
        # if this is interactive shell, then bind hstr to Ctrl-r (for Vi mode check doc)
        if [[ $- =~ .*i.* ]]; then bind -x '"\C-r": "hstrnotiocsti"'; fi
        export HSTR_TIOCSTI=n

    else
        # tiocsti is enabled, bind as normal
        bind '"\C-r": "\C-a '"${hstr_loc}"' \C-j"';
    fi

    unset hstr_mode
    unset hstr_loc
fi

....in other words, hstr puts the command you select into the command prompt for you to review, and then hitting enter again will execute the command.

....if you are like me and have a version-controlled bin and .bashrc, then this may be useful if you simultaneously use machines with kernel versions both above and below 6.2.0.

Edit: it's mysteriously stopped working today. Investigating.

[pavel-kalmykov]

For the record, it does not work with kernel 6.9.3-76060903-generic and zsh either. My .zshrc file has the same contents as in hstr --show-configuration.

[epistax1s]

July 18, 2024

Kernel version: 6.8.0-38-generic hstr version: 3.1.0 (2023-04-18T08:50:00) I have placed hstr --show-configuration in my ~/.zshrc file.

It still doesn't work. The command is just printed but not executed (it worked on earlier versions of Linux).

[caretech-ca]

Same issue here: command is echoed, not executed.

Mint 22, using bash Kernel version: 6.8.0-40-generic #40-Ubuntu SMP PREEMPT_DYNAMIC hstr version: "3.1.0" (2023-04-18T08:50:00)

hstr --show-configuration contents are appended to ~/.bashrc

It works from a root prompt ( sudo -i ) but not as regular user.

[mortan]

Same behavior for me (commands are echo'd but not executed):

uname -r
6.10.7-arch1-1

ZSH shell.

Is there any workaround for this problem?

Edit: ok this seems to work: https://github.com/dvorka/hstr/issues/452#issuecomment-1625158519
