Shazron Abdullah commented on CB-330:
-------------------------------------

@Edgar native db support is a good idea, please file a feature request - since 
all platforms will need to support this, and we need to have a discussion 
between all devs for this new feature.

The time to the next version being out (Mar 26th) is short, and adding a whole 
new feature that people depend on, is not a trivial effort. This fix is for 
people that need to get this fixed immediately (those that have apps already in 
the App Store and users are already complaining). That's why I took the time to 
make this a plugin that previous versions of Cordova could use as well.

This method does not lose data - if you see where the backup is done in the 
code, it is done on app pause and terminate, and is synchronous.

> Dear Dev
> WebKit data (localstorage or local SQLite) are now stored in Library/ Caches 
> folder (instead of Library/WebKit folder). This is a big problem for all apps 
> using UIWebView and storing user data, because they will no longer be backed 
> up and may be deleted. There are a lot of apps using localstorage or SQLite 
> as a critical feature. 
> The SQLite database gets deleted because the database is saved in a location 
> on the filesystem which Apple does not consider to contain persistent data.
> *Steps to Reproduce:* 
> In a UIWebView, create a new DB or use localStorage with JavaScript. 
> You can see that the WebKit data is now stored in Library/Caches :  
> *Expected Results:*
> We should at least specify the directory of WebKit data (and to set it 
> to Documents/ for critical data) 
> *Actual Results:* 
> The WebKit data are stored in Library/Caches folder, and can be 
> deleted 
> *Regression:*
> To migrate database location from Library/Caches to some other location such 
> as Documents.
