Subject: Unable to restore suspended function
Date: Thu, 25 May 2023 23:30:56 -0400 (EDT) [thread overview]
Message-ID: <b2a87d75-91e4-56cc-1cf4-c0e25c6787d7@farley.org> (raw)
I have a simple function to page output of ls. With Zsh 5.8.1 (and
earlier), I could suspend it then restore it with fg. With Zsh 5.9, it
enters some odd state where I have to call fg a few times before it
exits (FreeBSD). It never restores less. I tested this with FreeBSD
and Linux. It works as expected with both FreeBSD's sh and bash.
Test environment (bare bones with no Zsh files in /tmp/zsh):
mkdir /tmp/zsh
env -i ZDOTDIR=/tmp/zsh TERM=${TERM} HOME=${HOME} USER=${USER} zsh
pll() { /bin/ls -lF "${@}" | less; }
Test output (FreeBSD):
% pll /tmp/zsh
total 0
(END)
---- Ctrl+z ----
zsh: done /bin/ls -lF "${@}" |
zsh: suspended
% fg
[1] + done /bin/ls -lF "${@}" |
continued
zsh: done /bin/ls -lF "${@}" |
zsh: suspended (tty output)
zsh: done /bin/ls -lF "${@}" |
zsh: suspended (tty output)
% fg
(END)zsh: done /bin/ls -lF "${@}" |
zsh: suspended (tty input)
zsh: done /bin/ls -lF "${@}" |
zsh: suspended (tty input)
% fg
[1] + done /bin/ls -lF "${@}" |
continued
zsh: done /bin/ls -lF "${@}" |
zsh: suspended (tty output)
zsh: done /bin/ls -lF "${@}" |
zsh: suspended (tty output)
% fg
[1] + done /bin/ls -lF "${@}" |
continued
Linux is similar but never exits. It just outputs the "tty output"
blocks each time fg is called.
