Bug ID: 469328
Summary: Applications launched from Hotkeys/Shortcuts are
missing standard-streams (stdin, stdout, stderr) in
Wayland
Classification: Applications
Product: systemsettings
Version: 5.27.4
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_khotkeys
Assignee: k...@michael-jansen.biz
Reporter: qemxa2jneu.bugs.kde....@ruekov.eu
CC: plasma-b...@kde.org
Target Milestone: ---
SUMMARY
When an application is launched from a hotkey in Wayland (havent tested X11),
it doesnt have stdin, stdout, stderr attached which can result in problems when
these applications try to use them for e.g. logging.
This problem was noticed when using wl-clipboard which works when running it
from a script, but doesnt when running from a shortcut (e.g. as part of a
script)
STEPS TO REPRODUCE with wl-clipboard
1. Write script which uses wl-copy (e.g. wl-copy "foobar")
2. Add script as shortcut
3. Launch Keybind (press it!)
4. Check clipboard content
GENERAL STEPS TO REPRODUCE
1. Write script to test for stdin/stdout/stderr
# Test for stdout
if [ -t 1 ]; then
echo "stdout exists" >> /tmp/output
else
echo "stdout does not exist" > /tmp/output
fi
2. Launch directly and check /tmp/output
stdout exists
3. Launch via shortcut / keybind and check /tmp/output
stdout does not exist
EXPECTED RESULT
The standard streams should be connected e.g. stdout & stderr to system journal
or at least /dev/null
