Samuel Michelot commented on CB-330:
------------------------------------
Thanks for your quick answer Shazron. But after new testing, I can confirm that
there is a problem (at least in the iOS 4.3 simulator). To reproduce the
problem, I need to delete the app, then reinstall it, and launch it twice in
the iOS 4.3 simulator.
I added this log in the verifyAndFixDatabaseLocations :
NSLog(@"Error in database locations?: Old Value=%@, newValue=%@", value,
newBundlePath);
And I got this on the second launch (on the first launch, the fix is not
applied) :
Error in database locations?: Old Value=(null),
newValue=/Users/sam/Library/Application Support/iPhone
Simulator/4.3.2/Applications/E8484BD2-0BDF-4058-8121-CF14483F8440/Library/Caches
2012-04-17 15:52:30.896 Mosa_fr_es[10279:12e03] Fix applied for database
locations?: YES
And you can see in the following screenshot that 2 DB are created (in WebKit
for the first launch, and in Caches for the second launch) :

Maybe we shouldn't apply the fix if the value is null, or only call this method
when iOS >=5.1 ?

> 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.
