Shazron Abdullah commented on CB-2301:
--------------------------------------
Ah I see where the crash might happen now -- when the app is
backgrounded/locked, it does a backup of your localStorage, this call is async
but I don't think this is where the crash happens. I'm thinking it happens on
restore somehow:
https://github.com/apache/cordova-ios/blob/2ba2b39339336e274dd8583f260ff0d85e8e48b2/CordovaLib/Classes/CDVLocalStorage.m#L419
At least with your new information we can build a test-case to perhaps repro
it:
1. Set your config.xml BackupWebStorage project setting to the default
('cloud').
2. Read and/or write to localStorage on the resume event
(http://docs.phonegap.com/en/2.3.0/cordova_events_events.md.html#resume, see
iOS Quirks)
> EXC_BAD_ACCESS on resume/wake on iOS device

> Key: CB-2301
> URL: https://issues.apache.org/jira/browse/CB-2301
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS
> Affects Versions: 2.2.0
> Environment: iPhone 5 running iOS 6.0.2 and Phonegap 2.2.0. (Xcode
> 4.5.2 on Mountain Lion)
> Reporter: Ross Holdway
> Assignee: Shazron Abdullah
> Priority: Critical
> Labels: cordova, ios, phonegap
>
> I have implemented a websocket connection (using socket.io) within my app
> which it uses to communicate with the server. On locking and waking the
> device, it disconnects and reconnects correctly, but on leaving the device
> locked for 1 minute or longer when unlocking, the application will crash
> sometimes instantly, or sometimes after reconnecting with the server.
> If I do the same, but run my app within mobile Safari, it does not crash,
> leading me to believe this is an issue with Phonegap/Cordova.
> On app crash, within Xcode I get within WebThread -
> WebCore::ThreadTImers::sharedTimerFiredInternal() an EXC_BAD_ACCESS (code=1)
> error
> Screenshot of crash state in Xcode
> -http://pictat.com/i/2013/1/28/24904screenshot.jpg
> Hopefully someone will have an idea as to what could be causing this, or
> recommend some tests for me to run etc because I'm really clueless on how to
> proceed with fixing this!
> Many Thanks,
> Ross
