Program falsely detects crash after reboot as well as SIGHUP/SIGKILL/SIGTERM.

I would appreciate a switch to disable the crash detected pop up, this gets in the way of some automation software I'm writing for a disabled user who needs to be able to recover after a power outage or normal reboot without someone clicking the 'crash detected' window.

He cannot see the window and is probably going to do poorly with the introduction of a screen reader program so those aren't options either.

Regardless, I believe this software should be able to start up cleanly after a reboot while running. Is there a way to correct this behavior? Or can someone guide me on how to correctly close the program without using the GUI from CLI in linux?

Hello. Are you using X11? If so, xte "keydown Control_L" "key Q" "keyup Control_L" from a background shell may close foreground Gqrx window correctly without leaving "dirty shutdown" flag in a config file. Or you may add a new command to shutdown Gqrx to the remote interface (add a new branch here https://github.com/gqrx-sdr/gqrx/blob/master/src/applications/gqrx/remote_control.cpp#L214-L263)

It appears as though "xte" is not installed by default on my arch linux installation (arch has gqrx 2.16, Debian is stuck on 2.15.something for now)

Although I think I'm just going to script copying a known-good config over top of the last default config to remove the crash flag! I didn't realize that would be so simple to remove the crash flag.

It would still be good for the program to handle a reboot without thinking it crashed though, it should be able to accept those signals gracefully without thinking it crashed. like if I start it from cli and then ctrl-c it, that's not a crash...

Right now I'm going to just

echo "[General]" >> /home/username/.config/gqrx/default.conf
echo "configversion=3" >>  /home/username/.config/gqrx/default.conf
echo "crashed=false" >>  /home/username/.config/gqrx/default.conf

to brute force a fix for myself...but I feel like sighup/sigterm/ a regular reboot should not generate a crash...

Ideas?

I'd prefer to stay with mainline code and not run a custom branch that has unique shutdown remote commands, would you all be open to a remote control shutdown command? What command would you like? "Q PROGRAM" or something?

Edit I mean would you be open to a pull request for the exit shutdown command?

I would recommend

0x87 set_powerstat 0 

Per https://www.mankier.com/1/rigctl to maintain compatibility with rigctld

It looks like it's possible (although not simple) to handle Unix signals in a Qt application: https://doc.qt.io/qt-6/unix-signals.html

However, I'd prefer to avoid platform-specific code like that if possible.

The set_powerstat idea sounds reasonable.
