Hello,

For Linux some users complain from time to time that SmartGit does not store its settings when Linux is shut down while SmartGit is running. SmartGit stores its settings when it is cleanly exited - either by closing all windows (main shells), by invoking the exit menu item or by the display's Close-listener.

Could it be that the display's Close-listener is not invoked if Linux sends a SIGTERM signal to tell the application to exit? How much time a Linux application usually has to react on the SIGTERM signal? Thanks in advance.

This is a good example on how to handle SIGTERM - https://airtower.wordpress.com/2010/06/16/catch-sigterm-exit-gracefully/ . In general there is no limitation for the time the handler should take but note that it will eventually receive SIGKILL if it takes too long. It's worth trying whether your CloseListener is called when killing the process with console kill. I have never looked into whether SWT does smth like that.
