Sync issue: Implement single instance about lutris HOT 8 CLOSED

yes, that's a though one. The installer opened from the web is another instance that the already running client. The installer would need to notify other instances of the new game with, for example, DBus. And I know nothing about DBus :/

And if you allow only one instance ?

No. Not going to happen any time soon.

I mean, it will eventually happen, but when it will, the DBus communication mechanism will be implemented, because I see it as a requirement in order to limit to one instance of the client

Some info and code snippets for what you want to do :

Otherwise, maybe we could do it the stupid way : create a file when running Lutris, if another instance is launched it checks if the file exists, writes its arguments in it and closes. The first instance then reads the file and treats the args. Like so :

if File exists: 
    write args into File
    end process
else
    create empty File

on_check_File_size_frequently {
    if File.size > 0
        process args
    else
        return
}

on_exit {
    remove File
}

Thanks for the link! Tried out the demo, works flawlessly. I originally thought that you had to register a DBus service as root, but it's not the case here.
Makes me want to have a deeper look into Dbus, we may have this for Lutris 0.3.5 ;)

(Note that Gtk has this built in via GtkApplication as used in my PR)

Argh.
Well, Google, you did a bad job this time.

I'll let @strycore see what he wants to do with that. (Ehh, I suppose the advantage of not using GtkApplication is that it simplifies porting to another toolkit.)
