My Chrome Browser just updated it self from v39 to v40 (40.0.2214.91 m) and my application I'm developing just stopped working.
It seems they removed webkitPersistentStorage from the Worker navigator object. It is still there in the main navigator object.
The data type of the object was DeprecatedStorageQuota in the Worker navigator and still is so in the main navigator.
Can anyone tell me how to access this object the correct way? I guess they removed it because it was deprecated, but why only from workers and not the main thread? And where has this functionality gone now?
I need it to download files in the background (in a Web Worker) (this is not a normal web application used on the Internet, it's for an unmanned embedded systems appliance).
I just independently found this: https://crbug.com/604292. It was deleted by accident a long time ago (though my rough calculations put this deletion at at Chrome 39, not 40; see Comment 1) and not many people noticed apparently.
Unfortunately, because it is deprecated, we made the decision to not put it back in, so this will not be fixed. Instead, the standardized WorkerNavigator.storage will be available (but that is currently experimental only).
