[Bug]: GNU stty: 'standard input': unable to perform all requested operations

[xiaozhuai]

What did you expect to happen?

No warnning.

What happened?

It shows

stty: 'standard input': unable to perform all requested operations

How to repro:

1. Input ls -al
2. Press Enter
3. Press Up
4. Press Enter

But the following is ok with no warning

1. Input ls -al
2. Press Enter
3. Press Up
4. Press Tab
5. Press Enter

BTW, I use bash on macOS, and install bash-preexec using brew.

[ -f /opt/homebrew/etc/profile.d/bash-preexec.sh ] && . /opt/homebrew/etc/profile.d/bash-preexec.sh
eval "$(atuin init bash)"

Atuin doctor output

BTW, I use bash on macOS, and install bash-preexec using brew.

[ -f /opt/homebrew/etc/profile.d/bash-preexec.sh ] && . /opt/homebrew/etc/profile.d/bash-preexec.sh
eval "$(atuin init bash)"

The setup might not be working correctly. Your result of atuin doctor contains the following message:

[Shell] If you are using Bash, Atuin requires that either bash-preexec or ble.sh be installed. An older ble.sh may not be detected. so ignore this if you have it set up! Read more here: https://docs.atuin.sh/guide/installation/#bash

This implies that the bash-preexec is not detected in interactive sessions. What is the result of the following commands (in a session where the error message arises)?

$ ls -la /opt/homebrew/etc/profile.d/bash-preexec.sh
$ declare -p __bp_imported

If you also use ble.sh, it might also be related to ble.sh. I received a report to ble.sh with the same error message in macOS but couldn't get the details. Although I don't have a macOS system, it doesn't seem to reproduce in all the macOS environments since I only received the report twice (including this) although there are many macOS users. If it is related to ble.sh, I need your help to identify the cause.

If you use ble.sh, could you check the results of the following commands?

$ type -a stty
$ declare -p _ble_term_stty_flags_{enter,leave}
$ type ble/bin/stty

[xiaozhuai]

$ ls -la /opt/homebrew/etc/profile.d/bash-preexec.sh
$ declare -p __bp_imported

I didn't install ble.sh

$ type -a stty
$ declare -p _ble_term_stty_flags_{enter,leave}
$ type ble/bin/stty

Ok, I got it. I install gnu coreutils, which provide a stty in /opt/homebrew/opt/coreutils/libexec/gnubin/stty.
After I remove /opt/homebrew/opt/coreutils/libexec/gnubin from PATH, it works without warning.
But when I exec atuin doctor, the warning is still there, is it safe to ignore?

Why atuin didn't work with gnu coreutils?

[xiaozhuai]

The stty is bsd stty provided by macOS.
The gstty is gnu stty provided by coreutils package in homebrew.

OK. It is known that stty from GNU coreutils doesn't work in macOS. You should set PATH up so that /bin/stty is found first. For example, you can put a symbolic link to /bin/stty in ~/bin or some directory appearing in PATH earlier than /opt/homebrew/opt/coreutils/libexec/gnubin.

The first picture of #2027 (comment) tells that bash-preexec is correctly loaded in your session, so you can ignore the above warning message. The detection by atuin doctor is not perfect, so it might raise a false-positive error.

Why atuin didn't work with gnu coreutils?

Because Atuin uses stty in its integration for bash-preexec. If stty in the system is not working, it causes a problem.

[xiaozhuai]

@akinomyoga Thank you very much.

If stty in the system is not working, it causes a problem.

I've tried gnu's stty, it works well. Anything I can do to help?

Given the existence of this issue, I don't think this statement is accurate.

Using a mixed userspace is unlikely to work well across tools. Please use the BSD/macOS stty - I can't think of a reason as to why you'd prefer to use the GNU one?
