Hi all, This is probably a question for someone from the LC team who works on the engine. If anyone else is familiar with how LC quits on macOS please chime in though.
Scenario: I am running tests with the Sparkle.framework on macOS (which I already use) with the goal of silently and automatically downloading updates for an application that will be installed the next time the user quits the application. You can see similar behavior in apps such as Slack. Sparkle support: Sparkle supports this type of behavior if you set some properties. It checks and downloads an update to the local cache and then installs the update when the hosting app graceful terminates. Problem: I have confirmed that Sparkle downloads the updates to the cache but the update is never installed when I quit. I'm wondering if this is due to the use of exit(t_exit_code) in -applicationWillTerminate in mac-core.mm. Additional Info: While researching the problem I found an issue in the Sparkle Github project which had some interesting information in it. The author of the issue mentions that the app terminates by calling exit(0): https://github.com/sparkle-project/Sparkle/issues/1047#issuecomment-298029934 The maintainer says that Sparkle only supports graceful termination via Cocoa notification: https://github.com/sparkle-project/Sparkle/issues/1047#issuecomment-298041354 So I started looking through the LiveCode source code to see how LiveCode terminates an app when `quit` is called in LiveCode Script. If found mac-core.mm which has the main run loop which calls `[NSApp terminate: self];` when it is time to quit: https://github.com/livecode/livecode/blob/develop/engine/src/mac-core.mm#L360 That looks right. But farther down in applicationWillTerminate I found a call to `exit(t_exit_code)`; https://github.com/livecode/livecode/blob/develop/engine/src/mac-core.mm#L416 I'm wondering if that call to exit() is what is causing problems as my understanding is that exit() immediately causes an app to terminate. Perhaps exit() should only be called if t_exit_code > 0? -- Trevor DeVore ScreenSteps www.screensteps.com _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
