sandbox

How does Google App Engine sandbox work? What would I have to do to create my own such sandbox (to safely allow my clients to run their apps on my engine without giving them the ability to format my disk drive)? Is it just class loader magic, byte manipulation or something? You would probably need a combination of a restrictive classloader and a thorough understanding of the Java Security Architecture . You would probably run your JVM with a very strict SecurityManager specified. In the Java case, I think it's mostly done by restricting the available libraries. Since Java doesn't have pointer

I have Auto-Renewable In-App Purchase item in my application which is in development stage. I could able to test the complete transaction till 2 days ago with different sandbox test accounts (+abc@def.com).

However, I wanted to give the new build a once-over testing, including retesting our in-app purchase (there is only a single purchasable item in the app). And now the app crashes when doing the initial retrieval of the product information. It never crashed in this way before, and the code hasn't changed since we successfully tested the in-app purchase in sandbox mode many times. (In fact, no code changed at all between the initially

I realize that I'm a bit late to the game here in getting sandbox-ready, but so it goes. I'm developing for OS X 10.9. The app displays Calendar event data, but does not allow editing, so I have enabled the Calendars capability. The app works great with sandboxing enabled when I run it from Xcode, but when I export it signed with Developer ID, the app runs, but can't access the Calendar data. What's more, the system never asks me to allow the app to access Calendar data. When I run the app, it launches, but doesn't show any data. In Console, sandboxd throws a bunch of errors that look like
