I want to have the ability to relaunch my app programmatically, e.g.
after update or crash. I have checked the Sparkle Update's
implementation of relaunch and I found a little helper app called
"relaunch" (put into Resources). The main executable launches the
helper app passing its own path and process id in parameters. Then the
main executable terminates and the helper app waits for that by
polling until the main process id becomes invalid. Then the helper app
relaunches the main app using -[NSWorkspace openFile].
This seems to be a good implementation (correct me if I'm wrong) and
it works like a charm in Sparkle Update (sparkle.andymatuschak.org).
However, when I tried to reuse this "relaunch" helper app, it does
work, but I've got a weird problem: On top of the relaunched main app,
the Terminal window appears with message:
Last login: Fri Feb 6 08:17:53 on ttys001
/[path to the main app] ; exit;
[my computer name]:~ [user name]$ [path to the main app] ; exit;
When I try to close the terminal window, I've got message: "Closing
this window will terminate the running processes: login, bash, [my
app]". And it's not lying :).
I'm not strong in things like console apps, UNIX etc. What am I doing
wrong? How to prevent the Terminal window from appearing? Thanks!
