Subject [jira] [Commented] (CB-330) localStorage / SQLDatabase no longer persistent after iOS 5.01 Update
Date Wed, 21 Mar 2012 06:11:47 GMT

    [ https://issues.apache.org/jira/browse/CB-330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13234143#comment-13234143

Emile khattar commented on CB-330:
----------------------------------

OK, i see cb347 is what verifyAndFixDatabaseLocations is doing.
So we still have the case when the user kills the app from the task manager, since onAppTerminate
and onResignActive are not being called. 
So i am thinking of backuping up everytime the localStorage is modified. Unless you propose
a better fix.

Thanks

> 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.
