[jira] [Created] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update
localStorage / SQLDatabase no longer persistent after iOS 5.01 Update
---------------------------------------------------------------------
Key: CB-330
URL: https://issues.apache.org/jira/browse/CB-330
Project: Apache Callback
Issue Type: Bug
Components: iOS
Affects Versions: 1.4.0, 1.3.0, 1.5.0
Environment: iOS 5.01
PhoneGap (Any version)
Xcode 4
Build.PhoneGap
Reporter: Amirudin Bin Mohamed Ghani
Assignee: Shazron Abdullah
Priority: Blocker
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.

This is gonna be a problem for us, not a big one, but a problem none the
less. Basically every time a user restarts the app they will have to
download all user images rather than getting them from cache. Phonegap is
working on a plugin that we can instal which will fix it. You can test it
on the new ipad to see what the user experience is like.

Hi,
I am wondering if Apple will approve apps that overwrite webkit database
files. Has anyone submitted such apps and got approved?
Thanks,

Paul DeFalco commented on CB-330:
---------------------------------
I was having trouble with trying to add a column to a table and found this thread with help from phonegap support. I know very little about Objective C and just use xCode to build my phonegap - Sencha Touch app.
When I try to implement the plugin in xCode I'm getting warnings similar to "Incompatible Objective-C types assigning 'struct PGPlugin ', expected 'struct CDVLocalStorage '".
The fix seems to be working but I don't like seeing all of those warnings.
Can anyone help?

-------------------------------------
@Angelo thanks for the report, it really helps.
This appears to be the same problem I commented on here: https://issues.apache.org/jira/browse/CB-347?focusedCommentId=13261034&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13261034
Can we continue there since this is really a CB-347 fix issue.

[jira] [Issue Comment Edited] (CB-330) localStorage / SQLDatabase
no longer persistent after iOS 5.01 Update

Yoh Suzuki edited comment on CB-330 at 3/22/12 12:13 AM:
---------------------------------------------------------
The plugin appears to be working correctly for me, but when I install over top on the phone (i.e. do an ad-hoc update, even with the same build), I don't have anything in localStorage the very next time the app is started. Closing the program immediately and relaunching it gives me what I previously had in localStorage. This does not happen with an older iOS.
@shazron -- you mentioned that "on a new install and first run, it will try to restore a non-existent backup, this is normal." Will this be fixed? This leaves localStorage unreliable.

The plugin appears to be working correctly for me, but when I install over top on the phone (i.e. do an ad-hoc update, even with the same build), I lose my localStorage. This does not happen with an older iOS. Is anyone else experiencing this issue?

@shazron
is this warning normal:
"Incompatible pointer types assigning to 'CDVPluginResult *' from 'PluginResult *'"
Also in the readme.txt: did you mean "didFinishLaunchingWithOptions" instead of "applicationDidFinishLaunching"
and "initWithWebView:self.webView" instead of "initWithWebView:theWebView" ?

----------------------------------
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

-------------------------------------
@Samuel you are correct. I will add the nil check here as well: https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVLocalStorage.m#L269 This fix should take care of the library/caches dupe database issue as well. I've examined the flow and if it has the problem in the .plist, this code block should take care of it based on the folder existing: https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVLocalStorage.m#L273-276 and the folder can only exist if the key exists (which we will check for now).

[jira] [Commented] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update
Posted by "Siep de Vries (Commented) (JIRA)" <ji...@apache.org>.

Siep de Vries commented on CB-330:
----------------------------------
I tested the (previous) plugin and it seems to work nice, taking above comments in consideration. I however have a question. In the code, I see quite some calls like (IsiOSVersion(@"5.1")) ? @"Library/Caches" : @"Library/WebKit" to determine which path should be used. I must say, I'm not familiar with the call IsiOSVersion, but what happens if Apple plans to rollout iOS5.2 or iOS6.0? Will these checks then return the old paths instead of the new paths?

[jira] [Issue Comment Edited] (CB-330) localStorage / SQLDatabase
no longer persistent after iOS 5.01 Update
Posted by "Yoh Suzuki (Issue Comment Edited) (JIRA)" <ji...@apache.org>.

Yoh Suzuki edited comment on CB-330 at 3/23/12 12:03 AM:
---------------------------------------------------------
This may be a silly question (I'm not an Objective-C programmer, nor am I familiar with native iOS development), but inside of verifyAndFixDatabaseLocations, if it requires a change to the plist (i.e. dirty), it writes out the plist file with the change to WebKitLocalStorageDatabasePathPreferenceKey.
Will this change take effect immediately? If not (i.e. if it requires an app restart to take effect), then this could be why localStorage data is missing until the second launch after installing over top.
Edit: OK, I see the [appPreferences synchronize], which I assume is supposed to make the change take effect immediately.

Yoh Suzuki commented on CB-330:
-------------------------------
@emile - I observed that in order to kill my app from the task manager, it first hits my breakpoint in onResignActive (because you actually have to leave the app in order to see it in the task manager), and then my breakpoint in onAppTerminate (when I kill it in the task manager). The act of holding the power button to turn the phone off also triggers onResignActive.
I figured this covers most scenarios, though there may be other situations (like losing power to the phone somehow, as you mentioned). If one of these other situations becomes a problem, I will definitely start making manual backup calls from JavaScript as you suggest. Thanks!
(In that scenario, the trick will be to not call backup too often. If I'm going to setItem 20 different things, I'd like to call backup just once after they're all set, especially if localStorage contains lots of data. Maybe a quick solution would be a buffered call to Cordova.exec backup.)

Thanks Shazron for working on this bug !
Just a question: this plugin change the working location of WebKit localstorage files, or it just regularly backup the files with a copy inside the Document folder ?

--------------------------
@Shazron PS: My first wild guess is that something is not right with the process of adding the files. I add them by doubleclicking on the Plugins folder and choosing Add existing files.
- I then select the files and get a popup asking me how to add them.
- I check the box that says 'Copy items into destination folder (if necessary)'
- I leave the radiobox choice about folders on 'Recursively create groups for any added folders'
- And I press 'Add'

----------------------------------
@edgar, if you read the code of the plugin you will see that logically no data should be lost at all.
// onAppTerminate is fired on UIApplicationWillTerminateNotification
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onAppTerminate) name:UIApplicationWillTerminateNotification object:nil];
http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIApplicationDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UIApplicationDelegate/applicationWillTerminate:
This method lets your application know that it is about to be terminated and purged from memory entirely. You should use this method to perform any final clean-up tasks for your application, such as freeing shared resources, saving user data, invalidating timers, and storing enough application state to reconstitute your application’s interface when it is relaunched. Your implementation of this method has approximately five seconds to perform any tasks and return. If the method does not return before time expires, the system may kill the process altogether.
five seconds should be enough i think
So in theory this fixed should be good to support people who are using localStorage and Sql storage.
And the problem i had should be to the error i did by placing the plugin call in the wrong place.
However i agree with you having some sort of a "natural" persistent storage
thanks everyone

Ah I see what the issue is. I looked at the console in xCode organizer. It appears that the application gets a new ID or there is an inconsistency in the ID and I'm getting deny file-write-create /private/var/mobile/Applications/F2BE3CCA-AB36-4498-A7B0-81CB6D643512. On subsequent closing down and reopening of the app, I no longer see that message:

@Yoh are you calling PhoneGap.exec(null, null, "CDVLocalStorage", "backup", []); anytime you modify the localStorage?

[jira] [Issue Comment Edited] (CB-330) localStorage / SQLDatabase
no longer persistent after iOS 5.01 Update

Davide Bertola edited comment on CB-330 at 3/25/12 8:42 AM:
------------------------------------------------------------
Hi, I solved this issue in my app before coming across the jira bug. My strategy is simple.
I move the default webkit databases (from both Caches/ for 5.0.1+ or Library/Webkit for older iOS)
from their location to a safe location inside Documents folder.
I do this only if the "source" database exists, and if "destination" in the safe location does not exists.
Then I update the app preferences to pick up the databases from my Documents folder.
This should be safe and simpler than backing up and restoring stuff around.
This is the code I call from my application:didFinishLaunchingWithOptions:
{code}
/* Fix problem with ios 5.0.1+ and Webkit databases described at the following urls:
* https://issues.apache.org/jira/browse/CB-347
* https://issues.apache.org/jira/browse/CB-330
* My strategy is to move any existing database from default paths
* to Documents/ and then changing app preferences accordingly

It is possible to remove the data storage quota limit for WebkitSQL by running simple sqlite queries on the sql files. I am currently doing this with my plugin https://github.com/davibe/Phonegap-SQLitePlugin using it from javascript code to open Databases.db and run the following queries:
{code}
update origins set quota = '999999999999' where origin = 'file__0';
update databases set estimatedSize = '999999999999' where name = '" + dbName + "';
Where db name is the name of the db being patched.
{code}
About the mentioned Phonegap SQLitePlugin.
I tried to use my sqlite plugin instead of the database interface offered by webkit. I have read Edgar Canas suggesting this. I can tell from my experience that for some reason It's much slower. The bottleneck seems to be passing long queries (I store jsons that are over 1Mb) from the webview to native code. WebkitSQLite does not suffer from this.
By the way I have plans porting it to Cordova, any suggestions are welcome.
was (Author: davibe):
Hi, I solved this issue in my app before coming across the jira bug. My strategy is simple.
I move the default webkit databases (from both Caches/ for 5.0.1+ or Library/Webkit for older iOS)
from their location to a safe location inside Documents folder.
I do this only if the "source" database exists, and if "destination" in the safe location does not exists.
Then I update the app preferences to pick up the databases from my Documents folder.
This should be safe and simpler than backing up and restoring stuff around.
This is the code I call from my application:didFinishLaunchingWithOptions:
{code}
/* Fix problem with ios 5.0.1+ and Webkit databases described at the following urls:
* https://issues.apache.org/jira/browse/CB-347
* https://issues.apache.org/jira/browse/CB-330
* My strategy is to move any existing database from default paths

--------------------------
@Shazron, after retrying for a third time I seem to have gotten something right, or done something else wrong. The old error messages have gone. I now get only one error regarding "isAtLeastiOSVersion".
I've seen the solution provided by @Sean to include a snippet defining isAtLeastiOSVersion in appDelegate.h. But that has not made a difference.
I seem to be so close yet so far from launching my app.
Undefined symbols:
"_IsAtLeastiOSVersion", referenced from:

Samuel Michelot commented on CB-330:
------------------------------------
I think I have found a bug. The verifyAndFixDatabaseLocations is called on the first install, even if it's on iOS4.3.
The consequences are that the LocalStorage files are stored in the Caches folder, even if we are before iOS 5.1.
Is it normal?

Any ideas? I did everything the README says, if I comment out the lines:
//[[UIApplication sharedApplication] endBackgroundTask: backgroundTaskID];
//backgroundTaskID = UIBackgroundTaskInvalid;
it works, but that honestly doesn't seem like a great idea.

[jira] [Issue Comment Edited] (CB-330) localStorage / SQLDatabase
no longer persistent after iOS 5.01 Update

-----------------------------------------------------------
@Yoh you are right the plugin is meant to backup when the app resignActive or beingClosed by the OS.
However you need explicitly backup after you call setItem or window.localStorage.foo=bar to support cases like when the users kill the app manually from the task manager, or when the user turn OFF/ON the phone, or maybe when the mobile turns off or whatever weird case my turn off the app without a backup.
I would suggest you implement something function mySetIem (bar) {
// window.localeStorage.foo = bar;
// backup: Cordova.exec(null, null, "CDVLocalStorage", "backup", []);
}
this will allow your storage to be more robust exept for the cases that you and @Brad hilighted, when we install on top of exsisting app,
Let's wait for @shazron to advise so we don't waste time.

is there any "step by step" list on how to apply the fix to an existing phonegap project (PG not CDV) ?

@edgar verifyAndFixDatabaseLocations is for a separate issue CB-347, and it would (and should) only run at startup anyway and it does - it runs before the webview loads and calls any javascript.

Shazron Abdullah commented on CB-330:
-------------------------------------
@edgar You have a valid point regarding intermediate changes (the manual app terminate scenario), I'll work a fix in to prevent mitigate this risk. To create a feature request, on the top right of jira, there is a "Create Issue" button - then you choose the "Issue Type" as "Feature Request". Make sure you add the right "components" (platforms) that you desire the feature to be in.
To further mitigate this risk - I can add callbacks in the backup and restore functions, so if you choose to periodically backup - you can wait for the callbacks to return before continuing.

Emile khattar commented on CB-330:
----------------------------------
that's what i thought, but i read Error not warning so i asked.
I fully aware what the bug is about, and what does this plugin do. But i find it a hassle to backup every-time i modify the localStorage.
let me have a look @CB-347

-------------------------------------
Thanks - I'll check on this tomorrow. Can you try testing using localStorage - that should work. Please attach your error log as well for me to verify that I am getting the same error results.

[jira] [Commented] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update
Posted by "Yoh Suzuki (Commented) (JIRA)" <ji...@apache.org>.

Yoh Suzuki commented on CB-330:
-------------------------------
This may be a silly question (I'm not an Objective-C programmer, nor am I familiar with native iOS development), but inside of verifyAndFixDatabaseLocations, if it requires a change to the plist (i.e. dirty), it writes out the plist file with the change to WebKitLocalStorageDatabasePathPreferenceKey.
Will this change take effect immediately? If not (i.e. if it requires an app restart to take effect), then this could be why localStorage data is missing until the second launch after installing over top.

[jira] [Commented] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update
Posted by "Daniel (Commented) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CB-330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13234470#comment-13234470 ]
Daniel commented on CB-330:
---------------------------
I still have issues with this plugin when running in the iOS 5.1 simulator.
I perform the following steps:
1. Start application with plugin installed
2. Create data into localstorage
3. Double press home button (now the task manager comes up with nothing in it)
4. Single press home button (we are taken back to the springboard, while application is still running in the background)
5. Double press home button (now the task manager comes up with the application running)
6. Hold the icon of the app and force it to close
7. Start the application again.
At this moment all data from localstorage is still present. Now I add extra data and i repeat steps 3,4,5,6,7
After two or three times you will see the message "Program ended with exit code: 0" in your debug log and the debugger disconnected from the process.
If I again add some new data and repeat steps 3,4,5,6,7 the newly created data is gone when the application at step 7.
Anyone else who is also able to reproduce the same?

--------------------------
Sorry to be so spammy. I noticed in the blog that you referenced that version 1.6.1 is out and fixes all these problems. So I am ignoring the problem above.
1.6.1 brings new issues, but I'll complain about those elsewhere.

@edgar You have a valid point regarding intermediate changes (the manual app terminate scenario - then clobbering of the existing database with latest changes with older backed up data on next startup), I'll work a fix in to mitigate this risk. To create a feature request, on the top right of jira, there is a "Create Issue" button - then you choose the "Issue Type" as "New Feature". Make sure you add the right "components" (platforms) that you desire the feature to be in.
To further mitigate this risk - I can add callbacks in the backup and restore functions, so if you choose to periodically backup - you can wait for the callbacks to return before continuing.

Shazron Abdullah commented on CB-330:
-------------------------------------
The steps 4 to 6 are incorporated in 1.6.1:
initialized at startup: https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVViewController.m#L167
which calls this init function to apply the fix:
https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVLocalStorage.m#L107
which fixes it here:
https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVLocalStorage.m#L243
also step 6 is here:
https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVLocalStorage.m#L309
This all happens before the UIWebView is loaded. Run the diagnostic plugin and report back - like I said, it might be an edge case in YOUR setup, I won't know until I see that report.

-------------------------------------
@Siep the naming of that macro is misleading - it really should be "IsAtLeastiOSVersion" - I'll change it.
@Emile - thanks! this is what late night coding does to you, you forget to test for < 1.5 :) Will fix.

-------------------------------------
I see what's going on. I was handling it for the localStorage case (and it works, according to my testing, with localStorage only. See my comment earlier about path not exists only for the first time).
WebSQL puts the db into another structure. I've done some testing, and listed the directory structures that I need to handle in the plugin. I've attached the screenshots.

[jira] [Commented] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update

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) :
http://cl.ly/3x0P0x3I3z0w040Z2K0Y
Maybe we shouldn't apply the fix if the value is null, or only call this method when iOS >=5.1 ?

[jira] [Issue Comment Edited] (CB-330) localStorage / SQLDatabase
no longer persistent after iOS 5.01 Update

------------------------------------------------------------
Hi, I solved this issue in my app before coming across the jira bug. My strategy is simple.
I move the default webkit databases (from both Caches/ for 5.0.1+ or Library/Webkit for older iOS)
from their location to a safe location inside Documents folder.
I do this only if the "source" database exists, and if "destination" in the safe location does not exists.
Then I update the app preferences to pick up the databases from my Documents folder.
This should be safe and simpler than backing up and restoring stuff around.
This is the code I call from my application:didFinishLaunchingWithOptions:
{code}
/* Fix problem with ios 5.0.1+ and Webkit databases described at the following urls:

What do you think ?
Also, I have a suggestion for this plugin.
It is possible to remove the data storage quota limit for WebkitSQL by running simple sqlite queries on the sql files. I am currently doing this with my plugin https://github.com/davibe/Phonegap-SQLitePlugin using it from javascript code to open Databases.db and run the following queries:
{code}
update origins set quota = '999999999999' where origin = 'file__0';
update databases set estimatedSize = '999999999999' where name = '" + dbName + "';
Where db name is the name of the db being patched.
{code}
About the mentioned Phonegap SQLitePlugin.
I tried to use my sqlite plugin instead of the database interface offered by webkit. I have read Edgar Canas suggesting this. I can tell from my experience that for some reason It's much slower. The bottleneck seems to be passing long queries (I store jsons that are over 1Mb) from the webview to native code. WebkitSQLite does not suffer from this.
By the way I have plans porting it to Cordova, any suggestions are welcome.

The plugin appears to be working correctly for me, but when I install over top on the phone (i.e. do an ad-hoc update, even with the same build), I lose my localStorage. I don't know my way around Objective-C or native iPhone development, but can anyone offer suggestions as to where to start? Is anyone else experiencing this issue?

-------------------------------------
@emile - it's normal, since you never created any WebSQL databases, those files were not created. I've got to clean the error logging up so it's not as verbose. This plugin is just a backup and restore system (I still don't think you know what this bug is about?), plus the fix for CB-347.

@Shazron - In Cordova 1.5.0, I do not see applicationDidFinishLaunching, and I do not see a UIWebView* inside of didFinishLaunchingWithOptions to pass to CDVLocalStorage initWithWebView. Was your recommendation meant for pre-Cordova projects?

Samuel Michelot commented on CB-330:
------------------------------------
After some testing, it looks like the plugin doesn't do the migration from WebKit folder to the Caches folder. It should happens when users upgrade to iOS5.1. I know that sometime, the WebKit folder is completely deleted during the iOS5.1 update, but sometime, it's still there...
Here is an example of code to handle that migration : https://gist.github.com/2009491 (just for inspiration, because it migrate everything to the Document folder, it's for the PGSQLitePlugin)

Yoh Suzuki commented on CB-330:
-------------------------------
@emile - I am not calling Cordova.exec(null, null, "CDVLocalStorage", "backup", []); (for 1.5.0) from JavaScript because the plugin's backup function is called in native code before the app closes. Setting breakpoints in Xcode confirms this. (I believe calling it from JavaScript is an option for those who don't want change AppDelegate.m in steps 4 and 5 of the plugin installation instructions.)

[jira] [Commented] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update
Posted by "Dewang Shah (JIRA)" <ji...@apache.org>.

Dewang Shah commented on CB-330:
--------------------------------
This issue seems to have returned after iOS 6. Looking at the code in CDVLocalStorage, there is a check for the version to be < 6.0
NSString* original = [[appLibraryFolder stringByAppendingPathComponent :
(IsAtLeastiOSVersion(@"5.1") && !IsAtLeastiOSVersion(@"6.0")) ? @"Caches":@"WebKit/LocalStorage"]
stringByAppendingPathComponent:@"file__0.localstorage"];
As a result data for a new app on iOS 6 is now lost when the app is closed and then restarted. Strangely enough the data is only lost on the first run. From the second run onwards data is persisted.

@Shazron - In Cordova 1.5.0, I do not see applicationDidFinishLaunching, and I do not see a UIWebView* inside of didFinishLaunchingWithOptions to pass to CDVLocalStorage initWithWebView. Was your recommendation meant for pre-Cordova projects?

@emile - I am not calling Cordova.exec(null, null, "CDVLocalStorage", "backup", []); (for 1.5.0) from JavaScript because the backup is called in native code in onResignActive and onAppTerminate. Setting breakpoints in Xcode confirms this. (I believe calling it from JavaScript is an option for those who don't want change AppDelegate.m in steps 4 and 5 of the plugin installation instructions.)

-------------------------------------------------------------
After some testing, it looks like the plugin doesn't do the migration from WebKit folder to the Caches folder. It should happens when users upgrade to iOS5.1 before that fix (before upgrading the app with the backup fix). I know that sometime, the WebKit folder is completely deleted during the iOS 5.1 update, but sometime, it's still there...
Here is an example of code to handle that migration : https://gist.github.com/2009491 (just for inspiration, because it migrate everything to the Document folder, it's for the PGSQLitePlugin)

Sean commented on CB-330:
-------------------------
@Davide I really like your idea of just changing the location of where data is saved. I added your code as the block that runs when didFinishLaunchingWithOptions runs but I get a compile error I think you might understand. I've never worked with this language so fixing it is not obvious to me.
NSString *localStorageSubdir = (IsAtLeastiOSVersion(@"5.1")) ? @"Caches" : @"WebKit/LocalStorage";
The error I get is:
Undefined symbols for architecture armv6:
"_IsAtLeastiOSVersion", referenced from:
-[AppDelegate application:didFinishLaunchingWithOptions:] in AppDelegate.o
ld: symbol(s) not found for architecture armv6
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Any help you, or anyone, can send my way is greatly appreciated.

Edgar Canas commented on CB-330:
--------------------------------
@Shazron, new to this.. where do I file a feature request?
Yes the solution you have works as a intermediate, problem is as Emile mentioned if the app is killed manually or even if the app dies or resets for whatever reason you will loose whatever data you had done before the last backup, since a backup will only be done when the apps gets closed/reopened. Any type or reset that being soft or app reset it will overwrite the exiting data with the previous backup, which is not a desired option. Is there a way you can update the app so that it checks for modify time or something before the data gets overwritten with an outdated backup?
The other option that I was looking at is to do a backup after every transaction but my database is around 7-20mb so not sure how efficient/quick would be do do frequent backups after any database change.

Hi @Sharon,
I'm wondering should:
return [ super webViewDidStartLoad:theWebView ];
actually be:
return [self.viewController webViewDidStartLoad:theWebView];
I get an error with the first version of the code, on PG 1.4.1.

[jira] [Updated] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update
Posted by "Shazron Abdullah (Updated) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CB-330?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shazron Abdullah updated CB-330:
--------------------------------
Attachment: CDVLocalStoragePlugin.zip
Updated plugin:
1.Updated README, with an extra step to make it easier for users that want the CB-347 fix only
2.Success/failure callbacks for the backup/restore JavaScript calls
3. verifyAndFixDatabaseLocations takes into account whether the folder path is actually there (iOS 5.1 does not mean the dbs will always be in /Library/Cache - quite inconsistent)

Edgar Canas commented on CB-330:
--------------------------------
Shazron, just wondering as to why the solution is only doing a copy instead of actually building a native client similar to: https://github.com/davibe/Phonegap-SQLitePlugin
Unless I missed something the solution above only does a backup and restore?
The problem with doing a backup and restore is that well you can loose data depending of when a backup is done, a better solution would be to run the database right from the documents folder similar, this way you don't need to do any backups and you are certain you will always get the latest file. The native client plugin seems to work fine except for null values.
Can we get native DB support into Cordova instead of having to worry to when to do backups and restores?

----------------------------------
i am not sure if onResignActive and onAppTerminate are being fire when the app is killed by the kernel or manually by the user.
We need to have a look at the apple docs. Unfortunately i don't have an ios5.1 device in my hand to do more tracing, and on the simulator i can't reproduce

Yoh Suzuki commented on CB-330:
-------------------------------
The plugin appears to be working correctly for me, but when I install over top on the phone (i.e. do an ad-hoc update, even with the same build), I lose my localStorage. I don't know my way around Objective-C or native iPhone development, but can anyone offer suggestions as to where to start? Is anyone else experiencing this issue?

Attachment: CDVLocalStoragePlugin.zip
The plugin is attached, with instructions for PhoneGap versions <= 1.4.1, and a separate one for 1.5.0 only. In 1.6.0 (coming in a couple of weeks), this will already be included.
Please test and let me know any feedback.

--------------------------------
verifyAndFixDatabaseLocations works but it requires the app to be closed via task manager then opened up again. Otherwise on the first try it will fail to load the database.

[jira] [Issue Comment Edited] (CB-330) localStorage / SQLDatabase
no longer persistent after iOS 5.01 Update

---------------------------------------------------------
The plugin appears to be working correctly for me, but when I install over top on the phone (i.e. do an ad-hoc update, even with the same build), I lose my localStorage. This does not happen with an older iOS. Is anyone else experiencing this issue?

Shazron Abdullah commented on CB-330:
-------------------------------------
@Yoh - "on a new install and first run, it will try to restore a non-existent backup, this is normal." -- this is because in a new app, there is nothing to restore. I've fixed it so it doesn't report anything, except on success (to be released soon).
@Daniel - (programmatically modify the localstorage/websql location) - yes. You can do that by looking how in the code for verifyAndFixDatabaseLocations. I'm reluctant to support that because of the risk of side effects out of my control (who knows what things possibly WebKit or UIKit relies on... until its too late)
@Emile - this upcoming version should streamline the backup/restore. I'm checking for file modification dates now, and it will only proceed if a backup or restore is newer.
@Yoh - see CB-347, I suggested to someone to move code to applicationDidFinishLaunching instead of webViewDidStartLoad and that fixed the problem. I'll add this in the README

---------------------------
Would it be possible to programmatically modify the localstorage location? This would be a perfect solutions for applications that do not need to worry about migrating data from previous locations (which is the case for my project).

---------------------------
I also have the armv6 as a target architecture (iPhone 3G) and adding this plugin to the project gives me the following compilation error:
21-Mar-2012 10:32:48 [exec] Ld build/Release-iphoneos/Eppy.app/Eppy normal armv6
21-Mar-2012 10:32:48 [exec] (1 failure)
21-Mar-2012 10:32:48 [exec] Undefined symbols for architecture armv6:
21-Mar-2012 10:32:48 [exec] "_OBJC_CLASS_$_CDVLocalStorage", referenced from:
21-Mar-2012 10:32:48 [exec] objc-class-ref in AppDelegate.o
21-Mar-2012 10:32:48 [exec] ld: symbol(s) not found for architecture armv6
21-Mar-2012 10:32:48 [exec] collect2: ld returned 1 exit status
Would it be an idea to only link to this header file if iOS >= 5.1? In that case I would expect the app to compile fine for older devices. (Since there will never be an iOS 5.1+ for armv6/iPhone 3G)

[jira] [Commented] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update

Emile khattar commented on CB-330:
----------------------------------
@Yoh you are right the plugin is meant to backup when the app resignActive or beingClosed by the OS.
However you need explicitly backup after you call setItem or window.localStorage.foo=bar to support cases like when the users kill the app manually from the task manager, or when the user turn OFF/ON the phone, or maybe when the mobile turns off or whatever weird case my turn off the app without a backup.
I would suggest you implement something mySetItem () {
// window.localeStorage.foo = bar;
// backup: Cordova.exec(null, null, "CDVLocalStorage", "backup", []);
}
this will allow your storage to be more robust expect for the we have @Brad and you and me when we install on top of exsisting app,
Let's wait for @shazron to advise so we don't waste time.

Hi Sean,
I faced the same issue. You need to place the following code fragment in AppDelegate.h file:
{code}
/*
* Returns YES if it is at least version specified as NSString(X)
*/
#define IsAtLeastiOSVersion(X) ([[[UIDevice currentDevice] systemVersion] compare:X options:NSNumericSearch] != NSOrderedAscending)

Zach Smith commented on CB-330:
-------------------------------
Ok I have applied this to 1.4.1. The app builds, seems to work fine, but when the home button is hit (in the simulator) I get "EXC_BAD_ACCESS" on line:
[[UIApplication sharedApplication] endBackgroundTask: backgroundTaskID];
from onResignActive in CDVLocalStorage.m
Any ideas?

[jira] [Issue Comment Edited] (CB-330) localStorage / SQLDatabase
no longer persistent after iOS 5.01 Update

------------------------------------------------------------
Hi, I solved this issue in my app before coming across the jira bug. My strategy is simple.
I move the default webkit databases (from both Caches/ for 5.0.1+ or Library/Webkit for older iOS)
from their location to a safe location inside Documents folder.
I do this only if the "source" database exists, and if "destination" in the safe location does not exists.
Then I update the app preferences to pick up the databases from my Documents folder.
This should be safe and simpler than backing up and restoring stuff around.
This is the code I call from my application:didFinishLaunchingWithOptions:
{code}
/* Fix problem with ios 5.0.1+ and Webkit databases described at the following urls:

What do you think ?
Also, I have a suggestion for this plugin.
It is possible to remove the data storage quota limit for WebkitSQL by running simple sqlite queries on the sql files. I am currently doing this with my plugin https://github.com/davibe/Phonegap-SQLitePlugin using it from javascript code to open Databases.db and run the following queries:
{code}
update origins set quota = '999999999999' where origin = 'file__0';
update databases set estimatedSize = '999999999999' where name = '" + dbName + "';
Where db name is the name of the db being patched.
{code}
About the mentioned Phonegap SQLitePlugin.
I tried to use my sqlite plugin instead of the database interface offered by webkit. I have read Edgar Canas suggesting this. I can tell from my experience that for some reason It's much slower. The bottleneck seems to be passing long queries (I store jsons that are over 1Mb) from the webview to native code. WebkitSQLite does not suffer from this.
By the way I have plans porting it to Cordova, any suggestion is welcome.

@edgar You have a valid point regarding intermediate changes (the manual app terminate scenario - then clobbering of the existing database with latest changes with older backed up data on next startup), I'll work a fix in to prevent mitigate this risk. To create a feature request, on the top right of jira, there is a "Create Issue" button - then you choose the "Issue Type" as "New Feature". Make sure you add the right "components" (platforms) that you desire the feature to be in.
To further mitigate this risk - I can add callbacks in the backup and restore functions, so if you choose to periodically backup - you can wait for the callbacks to return before continuing.

Yoh Suzuki commented on CB-330:
-------------------------------
@Shazron - That works!!! You are so awesome! Thank you so much!
I think verifyAndFixDatabaseLocations in your snippet need some parameters?
{code}
CDVLocalStorage* localStorage = [[CDVLocalStorage alloc] init];
[localStorage verifyAndFixDatabaseLocations:nil withDict:nil];
[localStorage release];
{code}
Also, do you think we can take out the call to verifyAndFixDatabaseLocations inside of initWithWebView, since we're doing it in application:didFinishLaunchingWithOptions?

-------------------------
@Daniel thank you very much. That worked for me. Unfortunately, the data in local storage did not persist after I killed the running app on my iPad and restarted it. Did you experience this?
Thanks in advance.

Shazron Abdullah commented on CB-330:
-------------------------------------
@Emile This is about persistence (try to read the original description again). The location of the databases are in Library/Caches which is not guaranteed to be be there in the case of an app upgrade, or iOS system cleanup (as per Apple rules). Previously it was guaranteed since it was in Library/WebKit.

@Yoh yup - was missing the params, sorry. Yes, it should only be called once, you can take out that call - but with the way the plugin is anyway, it will get called again (since every time you init the object, that gets called). All this will be cleaned up properly

Hi Shazron, I get two errors after setting up the CDVPlugin.
The error occurs while compiling AppDelegate.m and again while compiling CDVLocalStorage.h
In both cases, XCode says:
Cordova/CDVPlugin.h file not found.
I'm not sure what to do about this, since I am not an Objective-C programmer. Something that puzzles me in particular is that the content of the file CDVPlugin.h is nothing more than a bunch of comments and the command #import <Cordova/CDVPlugin.h>. To me it doesn't make sense that a file would try to import itself...

@Yoh you are right the plugin is meant to backup when the app resignActive or beingClosed by the OS.
However you need explicitly backup after you call setItem or window.localStorage.foo=bar to support cases like when the users kill the app manually from the task manager, or when the user turn OFF/ON the phone, or maybe when the mobile turns off for whatever reason without a backup.
I would suggest you implement something function mySetIem (bar) {
// window.localeStorage.foo = bar;
// backup: Cordova.exec(null, null, "CDVLocalStorage", "backup", []);
}
this will allow your storage to be more robust exept for the cases that you and @Brad hilighted, when we install on top of exsisting app,
Let's wait for @shazron to advise so we don't waste time.

-----------------------------------
Hi, I solved this issue in my app before coming across the jira bug. My strategy is simple.
I move the default webkit databases (from both Caches/ for 5.0.1+ or Library/Webkit for older iOS)
from their location to a safe location inside Documents folder.
I do this only if the "source" database exists, and if "destination" in the safe location does not exists.
Then I update the app preferences to pick up the databases from my Documents folder.
This should be safe and simpler than backing up and restoring stuff around.
This is the code I call from my application:didFinishLaunchingWithOptions:
{code}
/* Fix problem with ios 5.0.1+ and Webkit databases described at the following urls:
* https://issues.apache.org/jira/browse/CB-347
* https://issues.apache.org/jira/browse/CB-330
* My strategy is to move any existing database from default paths
* to Documents/ and then changing app preferences accordingly

What do you think ?
Also, I have a suggestion for this plugin.
It is possible to remove the data storage quota limit for WebkitSQL by running simple sqlite queries on the sql files. I am currently doing this with my plugin https://github.com/davibe/Phonegap-SQLitePlugin using it from javascript code to open Databases.db and run the following queries:
{code}
update origins set quota = '999999999999' where origin = 'file__0';
update databases set estimatedSize = '999999999999' where name = '" + dbName + "';
Where db name is the name of the db being patched.
{code}
I tried to use my sqlite plugin instead of the one offered by webkit entyrely. I have read someone suggesting this. I can tell from my experience that for some reason It's much slower. The bottleneck seems to be passing long queries (I store jsons that are over 1Mb) from the webview to native code. WebkitSQLite does not suffer from this.

---------------------------------------
Hello,
I've read the entire thread, and installed Cordova-1.6.0 but i still have the issue reproducing itself.
Is there anything to do to Cordova 1.6.0 besides installing it in order to fix the issue ?
Is there some code or files i should search for to be sure I've installed correctly ?
Thanks,
Andy

----------------------------------
I thought the issue was fixed by just upgrading to Phonegap 1.6.1. It worked only after doing steps 4 to 6 described in the CDVLocalStoragePlugin-Readme.
This workaround should be documented somewhere (Wiki or Readme), because it's a crucial issue for every iOS App using WebSQL/Localstorage.

-------------------------------------
@Paul those warnings should be harmless (in your version's case with the compat. headers CDVLocalStorage is a CDVPlugin is a PGPlugin) - unfortunately to make it work on all versions I have to leave this warning in, if not it gets more complex with compile conditionals, and more instructions.
@Richard you are correct: https://github.com/apache/incubator-cordova-ios/blob/1.4.1/PhoneGap-based%20Application/Classes/AppDelegate.m#L173 (or change super to self, that should work I think as well). Sorry - a bit challenging testing for all versions!

-------------------------------------
Re: "Then I update the app preferences to pick up the databases from my Documents folder.
This should be safe and simpler than backing up and restoring stuff around."
I considered this but ultimately rejected it because of the possibility of side-effects. I mentioned this earlier here: https://issues.apache.org/jira/browse/CB-330?focusedCommentId=13236224&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13236224
I realize that CB-347 I am already modifying it - but that's only to "patch" their bug, not to re-direct the storage location which Apple may/may not frown upon.

Daniel commented on CB-330:
---------------------------
Hi Davide!
Thanks for posting your code here! Although I understand why Shazron decided to go and implement a more 'Apple compliant fix', I like the idea of changing the localstorage location itself much more. It feels more robust compared to going back and forth using backup-data.
First I put your code in the {code}webViewDidFinishLoad{code} method. However that was not working for me after restarting the program. Then I used your code in the {code}didFinishLaunchingWithOptions{code} method which worked perfectly.
I did modify one line of your code, because otherwise it creates 2 localstorage files in the Application/Documents folder:
{code}
// your code
NSString *ourLocalStorageDb = [documents stringByAppendingPathComponent:@"file__0.localstorage"];
// changed to
NSString *ourLocalStorageDb = [ourLocalStoragePath stringByAppendingPathComponent:@"file__0.localstorage"];
{code}

[jira] [Updated] (CB-330) localStorage / SQLDatabase no longer

(was: I also have the armv6 as a target architecture (iPhone 3G) and adding this plugin to the project gives me the following compilation error:
21-Mar-2012 10:32:48 [exec] Ld build/Release-iphoneos/Eppy.app/Eppy normal armv6
21-Mar-2012 10:32:48 [exec] (1 failure)
21-Mar-2012 10:32:48 [exec] Undefined symbols for architecture armv6:

21-Mar-2012 10:32:48 [exec] collect2: ld returned 1 exit status
Would it be an idea to only link to this header file if iOS >= 5.1? In that case I would expect the app to compile fine for older devices. (Since there will never be an iOS 5.1+ for armv6/iPhone 3G)

Shazron Abdullah commented on CB-330:
-------------------------------------
@Yoh it should be application:didFinishLaunchingWithOptions, correct - and yeah it's tricky because its designed to be a plugin that is resident (which is all handled properly in 1.6.0). All you need is for it to run it once to call verifyAndFixDatabaseLocations (for CB-347 fix) and also instantiate it in webviewDidStartLoad for CB-330 fix.
I'll clean this up, but for now (to fix CB-347) in application:didFinishLaunchingWithOptions do:
{code}
CDVLocalStorage* localStorage = [[CDVLocalStorage alloc] init];
[localStorage verifyAndFixDatabaseLocations];
[localStorage release];
{code}

[jira] [Issue Comment Edited] (CB-330) localStorage / SQLDatabase
no longer persistent after iOS 5.01 Update
Posted by "Davide Bertola (Issue Comment Edited) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CB-330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13237796#comment-13237796 ]

------------------------------------------------------------
Hi, I solved this issue in my app before coming across the jira bug. My strategy is simple.
I move the default webkit databases (from both Caches/ for 5.0.1+ or Library/Webkit for older iOS)
from their location to a safe location inside Documents folder.
I do this only if the "source" database exists, and if "destination" in the safe location does not exists.
Then I update the app preferences to pick up the databases from my Documents folder.
This should be safe and simpler than backing up and restoring stuff around.
This is the code I call from my application:didFinishLaunchingWithOptions:
{code}

What do you think ?
Also, I have a suggestion for this plugin.
It is possible to remove the data storage quota limit for WebkitSQL by running simple sqlite queries on the sql files. I am currently doing this with my plugin https://github.com/davibe/Phonegap-SQLitePlugin using it from javascript code to open Databases.db and run the following queries:
{code}
update origins set quota = '999999999999' where origin = 'file__0';
update databases set estimatedSize = '999999999999' where name = '" + dbName + "';
Where db name is the name of the db being patched.
{code}
About the mentioned Phonegap SQLitePlugin.
I tried to use my sqlite plugin instead of the database interface offered by webkit. I have read Edgar Canas suggesting this. I can tell from my experience that for some reason It's much slower. The bottleneck seems to be passing long queries (I store jsons that are over 1Mb) from the webview to native code. WebkitSQLite does not suffer from this.
By the way I have plans porting it to Cordova, any suggestion is welcome.

I think I have found a bug. The verifyAndFixDatabaseLocations is called on the first install, even if it's on iOS4.3.
The consequences are that the LocalStorage files are stored in the Caches folder, even if we run in iOS version before 5.1 (tested in the simulator in 4.3).
Is it normal?

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.

[jira] [Updated] (CB-330) localStorage / SQLDatabase no longer

Posted by "Shazron Abdullah (Updated) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CB-330?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shazron Abdullah updated CB-330:
--------------------------------
Attachment: CDVLocalStoragePlugin.zip
Attached the latest version of the plugin. Backs up both the localStorage and WebSQL databases, and fixes CB-347.
Note that on a new install and first run, it will try to restore a non-existent backup, this is normal.

[jira] [Commented] (CB-330) localStorage / SQLDatabase no longer
persistent after iOS 5.01 Update

----------------------------------
@Yoh turning of the phone didn't work for me all the times, inconsistent results in this case.(at least for me)
Ok i agree you can implement your own backup logic i think it is case by case driven.
It looks hard to fully mimic the localStorage setItem/getIten and unfortunately we can't re-compile webkit so we have to survive with these workaround untill we have a better persistent storage apis from cordova.
Keep us posted with your observations
